Situation analysis and prospect of new building materials industry in this section

I. Analysis of Development Situation China's new building materials industry has developed with the deepening of reform and opening up. 1979 to 1998 is an important historical period for the development of new building materials in China. After 20 years of development, China's new building materials industry has basically completed the development process from scratch, from small to large, and has formed a new industry nationwide, becoming an important product category and a new economic growth point in the building materials industry. The rapid development of economic construction and the continuous improvement of people's living standards provide good opportunities and broad markets for the development of new building materials. It is estimated that the output value of new building materials will account for nearly 20% of the total output value of building materials industry in 1999. At present, there are many new building materials enterprises all over the country, and driven by market demand, a nationwide newspaper-style building materials circulation network has been formed. Most foreign products have been produced in China, and the new building materials needed for three-star hotels have been self-sufficient in China; The development of decorative materials with different grades and colors has provided material guarantee for improving the living conditions of urban and rural people in China and changing the appearance of cities. China has formed a professional team of scientific research, design, education, production, construction and circulation of new building materials. 1, development of new wall materials China's new wall materials have developed rapidly. 1987 The output of new wall materials1845 million standard bricks, 1997 increased to 184988 million standard bricks, an increase of 10 times. The proportion of new wall materials in the total wall materials increased from 4.58% to 25.2%. There are many kinds of new wall materials, mainly including bricks, blocks and boards, such as clay hollow bricks, clay bricks mixed with waste materials, non-clay bricks, building blocks, aerated concrete, lightweight boards and composite boards. , but the number is small. In the final wall materials, the ratio of site to land is still small. Only by promoting the rapid development of various new bulk materials according to local conditions can we change the unreasonable product structure of wall materials and achieve the purposes of saving energy, protecting cultivated land, utilizing industrial waste residue and popularizing construction technology. After nearly 20 years of research and development of the first set of foreign production technology and equipment, China's wall material industry has embarked on the road of multi-variety development, and initially formed a wall material system based on blocks, such as concrete hollow blocks, gypsum boards, fiber cement sandwich panels and so on. However, the proportion of various lightweight boards and composite boards representing the modern level of wall materials is still very small, accounting for less than 1% of the total wall materials. Compared with developed countries, it is mainly manifested in: low product grade, small enterprise scale, backward technical equipment and poor supporting capacity. An important reason for the slow development of new wall materials is that there are no restrictions on solid clay bricks, and there are no specific measures to protect land resources. The cost of making clay bricks at the expense of destroying land is extremely low, which makes any new wall materials unable to compete with them in price. After the implementation of the new tax system of 1994, only 6% value-added tax is levied on clay brick production enterprises, but many new wall materials, especially light plates, have to pay the value-added tax bureau of 17%, which intensifies the unfavorable situation of the development of new wall materials. In view of this situation, the office of wall material innovation of three ministries and commissions and one bureau (Ministry of Construction, Ministry of Agriculture, Ministry of Land and Resources, and State Building Materials Bureau) actively guides all localities to vigorously carry out wall material innovation, and combined with local conditions, has issued a number of wall reform policies, which has effectively promoted the development of new wall materials. 2. Thermal insulation materials Before 1980, the development of thermal insulation materials in China was very slow. A few thermal insulation materials factories can only produce a small number of products, such as expanded perlite, expanded vermiculite, slag wool, superfine glass wool, microporous calcium silicate and so on. The variety, specifications and quality of products can not meet the needs of national construction. Compared with foreign advanced level, it is at least 30 years behind. For example, before 1980, there were only three factories producing cotton residue in China, and the annual average production capacity was less than 1 10,000 tons. There were only three companies producing calcium silicate insulation materials, with an annual output of about 8,000 cubic meters. Since the reform and opening up, China's insulation materials have made great progress, and have developed into a relatively complete variety of insulation materials production and technical system that has begun to take shape. 1996 The national output is about 800,000 tons, including 200,000 tons of mineral wool, 40,000 tons of glass wool, 50,000 beans of foamed plastics, 6 million cubic meters of expanded perlite (including 450,000 tons) and 60,000 tons of other materials. The main gaps between China's thermal insulation materials and developed countries are as follows: ① The largest user of thermal insulation materials abroad is the construction industry, accounting for about 80% of the output. However, China's construction market has not been fully opened, and its application only accounts for 65,438+00% of the output. ② The overall level of production technology and management needs to be further improved, and the product quality is not stable enough. (3) Insufficient investment in scientific research, lagging application technology research and product development, especially the slow progress in application technology research and development of building insulation materials for many years, which has seriously affected the healthy development of the insulation materials industry. Strengthening the design, construction and application of new building materials such as new thermal insulation materials is an urgent task to develop new rural construction industry. It can be seen from the above situation that after more than 30 years' efforts, especially the rapid development in recent 20 years, many products have grown from scratch, from single to diversified, from low to high, forming a relatively complete variety of industries, mainly expanded perlite, mineral wool, glass wool, foam plastic, refractory fiber and calcium silicate insulation products, and the technical level and production equipment have also been greatly improved. Some products have reached the international advanced level in the 1990s. However, due to the late start of China's thermal insulation material industry and the low level of overall technology and equipment, the application technology in the construction field needs to be improved, which greatly affects the popularization and application of thermal insulation materials. In recent years, the phenomenon of repeated construction in thermal insulation materials industry is serious. Hundreds of production lines have been put into production within a few years, but little investment has been made in the development of application fields, resulting in low investment benefit and oversupply. 3. Waterproof sealing materials Waterproof materials are important functional materials needed by the construction industry and other related industries, and are an important part of the building materials industry. With the rapid development of China's national economy, not only industrial buildings and civil buildings put forward high-quality requirements for waterproof materials, but also industries and fields such as bridges, tunnels, national defense and military industry, agricultural water conservancy, transportation and so on need high-quality waterproof sealing materials. Since the reform and opening up, China's building waterproof materials have developed rapidly. Waterproof materials are out of the backward situation under the uniform hem of paper-based linoleum. At present, they have five categories of products: asphalt felt (including modified asphalt felt), synthetic polymer waterproofing membrane, building waterproof coating, sealing material, plugging material and rigid waterproof material. From 65438 to 0995, the output of new waterproofing membrane was 42 million square meters, accounting for about 5% of the output of waterproofing membrane. China has basically formed a waterproof material industrial system with complete varieties and matching product specifications and grades, and the development of technical equipment has begun to take shape. We basically have some varieties abroad. At present, compared with foreign advanced countries, China's waterproof materials mainly have the following problems: First, the product structure is unreasonable. At present, the output and usage of new waterproof sealing materials are very small, and paper tire linoleum still accounts for 95% of waterproof coiled materials; Second, the quality of products is generally low, and counterfeit and shoddy products flood the market; Third, the design and construction application technology needs to be improved, and the building leakage is still quite serious. Waterproof material industry urgently needs to adjust its structure and standardize its market. 4. Decoration materials There are many kinds of building decoration materials, which are updated quickly and are closely related to the improvement of people's living standards and living conditions. It is one of the building materials with great development potential. Its variety, quality and supporting level determine the level of architectural decoration, which is of great significance to beautify urban and rural buildings and improve people's living and working environment. Although the development of building decoration materials in China started late, it started at a high level, and its main production capacity was developed on the basis of introducing foreign advanced technology and equipment after the 1980s. At present, there are more than 4,000 varieties of colors, and an industrial system with relatively complete product categories has basically taken shape. 1995 the annual output value of decorative materials in China is about 40 billion yuan. 199 1- 1995, the annual growth rate of decoration materials in China is 30%. 1996 The output of main products is: wallpaper, wall 2 10/00000 square meters, plastic floor 36 million square meters, building paint 650000 tons, plastic pipe 90000 tons, plastic doors and windows nearly100000 square meters, and chemical fiber carpet 4.5 million square meters. At present, the decoration of three-star hotels is basically to help them produce, and 30%-40% of the decoration of four-star hotels can be self-sufficient. The main problems are: small scale of production enterprises, unstable product quality, outdated styles, low grade, poor matching and weak market competitiveness; The strength of scientific research and development is insufficient, and the ability of product upgrading is weak, which can not meet the market demand; The product structure is unreasonable, the proportion of middle and low-grade products is large, and the proportion of high-grade materials is low, which can not meet the needs of high-grade architectural decoration. Second, developing new building materials and products is the requirement of sustainable development strategy. For China, where per capita resources such as energy and cultivated land are only 1/4 of the world average, the coordinated development of national economy, society, resources and ecological environment is more important and urgent. At present, China's clay solid brick still accounts for nearly 80% of the total output of wall materials, and the problems of high energy consumption, land destruction and pollution are very serious. Each brick consumes 2.2 billion tons of clay resources, making bricks destroys about 6.5438+0.2 million mu of land, consumes 82 million tons of standard coal, and emits a lot of dust and carbon dioxide. Therefore, the development of organ newspaper building materials products is related to the implementation of China's sustainable development strategy and the healthy development of building materials industry. With the development of national economy and the gradual improvement of people's living standards, people's requirements for living and working places are also constantly improving. The experience of many countries proves that this is an inevitable trend of economic development and social progress. The progress of the construction industry requires not only the perfection of the quality and function of buildings, but also the beauty, which is harmless to human health. This requires the development of multifunctional and efficient new building materials and products. Only in this way can we meet the requirements of social progress. The use of new building materials and products can significantly improve the function of the building, increase the usable area of the building, improve the seismic capacity, facilitate mechanized construction and improve construction efficiency, and reduce the project cost under the same circumstances. Practice in Tianjin, Chengdu and other cities has proved that under the same conditions, the use of new building materials and products can increase the effective use area by nearly 10%, reduce the weight of buildings by more than 40%, and effectively improve the seismic capacity. If 10% of the 240 million square meters of urban housing completed every year adopts new materials, the effective use area can be increased by about 20 million square meters every year, and the comprehensive cost can be reduced by about 4%-7%. In addition, the development of new building materials also has significant effects on environmental protection and comprehensive utilization of resources. Taking the Eighth Five-Year Plan as an example, only developing new wall materials can save more than 22 million tons of standard coal for production and building heating. As the building materials industry with the strongest correlation with the construction industry, 70% of its products are used in the construction industry. The development of new building materials and products should be included in the architectural design and construction specifications, and the development of new building materials should be promoted by popularizing and applying new materials. Popularizing and applying new building materials not only has considerable social benefits, but also has remarkable economic benefits. For example, the cost of saving energy by using new thermal insulation materials in buildings is far greater than the increased cost of replacing clay solid bricks with new building materials. Therefore, developing new building materials and products is an important part of social progress and improving social and economic benefits. Three. The development prospect of new building materials and products According to the requirements of the cross-century development strategy of building materials industry, the development of new building materials will focus on new words and promote the adjustment of industrial structure. The output value of new building materials and products developed at a rate of about 20%-25% during the Ninth Five-Year Plan period, and by 2000, the output value was close to 654.38+0.3 billion yuan. Among them, the output value of independent accounting enterprises above township level is 80-90 billion yuan, accounting for 20% of the total output value of building materials industry. The quality of technology, equipment and products reached the international level in the 1970s, key enterprises reached the international level in the early 1980s, and advanced enterprises reached the international advanced level in the same period. . 1, some new building materials products in 2000 and 20 10 forecast (1) waterproof sealing materials.

New building materials industry will be the development focus of China during the Tenth Five-Year Plan (200 1-2005). The proportion of new wall materials in the total wall materials will increase from 28% at the end of the ninth five-year plan to 35%. The key point is to build a leading product production line with high grade, poor level and large scale. Hollow bricks focus on the development and utilization of load-bearing porous bricks with high slag content, high porosity, high thermal insulation performance and high strength and fair-faced wall bricks decorated with external walls; For concrete blocks, we will focus on the development of double-row or multi-row hole thermal insulation load-bearing blocks and exterior wall decorative blocks, focusing on the development of mechanized (extruded) light perforated slats, composite thermal insulation of exterior walls or assembled plates with decorative surfaces, and cooperate with the construction department to promote the application of light steel structure system and develop various assembled slats. Actively promote UPVC plastic pipes and other new plastic pipes. 80% of indoor drainage pipes, 90% of threading pipes and 50% of outdoor rainwater pipes are made of plastic pipes. Cast iron pipes are basically eliminated, and about 6.5438+0.6 million tons of various pipes and fittings are needed. 30% of indoor water pipes and 20% of indoor heating pipes use flexible plastic pipes. Urban water supply pipeline 50%; Plastic pipes are used in 80% water supply pipes in villages and towns, and plastic pipes are used in 15% sewer pipes. * * * About 200,000 tons of UPVC pipes are needed.

In accordance with the spirit of "grasping the big and letting the small go" and establishing "big enterprise groups" put forward by the 15th National Congress of the Communist Party of China, and in combination with local conditions, we will select a number of basic cities and powerful new building materials product production enterprise groups and bases for key development, and form large-scale new building materials product enterprise groups and production bases with large production scale and strong supporting capacity. Combined with the pilot work of housing industrialization, we will do a good job in the development of new building materials and products in a number of cities such as Beijing, Shanghai and Tianjin, and form a new material base with its own characteristics, reasonable leading products and product structure, and a certain scale and supporting capacity, which will play an exemplary role in other large and medium-sized cities across the country.

Edit this paragraph overview

"New building materials", referred to as "new building materials" for short, are new varieties of building materials that are different from traditional building materials such as bricks and tiles, lime sand and gravel. The scope of new building materials has been clearly defined in the industry, that is, new building materials mainly include four categories: new wall materials, new waterproof sealing materials, new thermal insulation materials and decorative materials.

Edit the third new building material in this paragraph: the substitute product of color steel plate.

—— Edit the fourth new building material in this paragraph: liquid wallpaper.

As the biggest wall decoration in building decoration, old building materials are wallpaper and latex paint. Compared with the old wallpaper: liquid wallpaper wallpaper

Firmly attached to the basic latex paint, never peeling. Using the sticking process, the glue peels off after aging.

There is no way to crack without joints. Joints crack easily.

Liquid wallpaper has stable performance, good durability, and discoloration-free wallpaper is prone to oxidation and discoloration.

Water-proof, scrub-resistant, and antistatic, dust is not easy to attach to wallpaper and is afraid of moisture, so special cleaners are needed to clean it.

It is very difficult to cover the secondary construction with paint.

The color can be adjusted at will, and the color is rich and relatively stable.

Rich patterns and personalized design. Passive color mode selection.

With pearlescent raw materials as pigments, wallpaper with color-changing effect is only effective for some high-end products.

Non-toxic and tasteless, safe to use, environmentally friendly and flammable.

Reasonable price, beautiful and fashionable price is relatively high.

Compared with traditional latex paint, the difference between liquid wallpaper and traditional paint is that liquid wallpaper belongs to water-based paint, which has strong stain resistance like traditional paint, good moisture-proof and antibacterial properties, and is not easy to get insects and age. The fifth new building material-carved metal board Dalian Jiahe carved metal insulation board has absorbed many advantages of modern wall materials at home and abroad. It is a kind of board with many functions, such as heat preservation, decoration, heat insulation, environmental protection, flame retardant, weather resistance, rain resistance, frost resistance, sound insulation, earthquake resistance, light weight, less land occupation and so on. It is the most popular and best-selling new lightweight energy-saving and environment-friendly building material in the world. Dalian Jiahe board has a variety of texture finishes such as brick pattern, spray pattern, wood grain, orange peel pattern, stripe and cultural stone pattern to choose from, and the coating will not fade for ten years. The plate specification is: 3000-6000*385* 16mm, and the standard specification is: 3800 * 385 * 16. 1. The energy saving effect is remarkable: 1. Dalian Jiahe plate is made of 0.30mm thick aluminum-zinc plated steel plate. The theoretical life of aluminum-zinc plated steel plate is 50 years, and the recovery rate is 99.9%, which effectively realizes energy reuse. 2. The middle insulation layer is made of high-density rigid foamed polyurethane, which is the most technologically advanced and environmentally friendly insulation material in the world. At the same time, after being used at high temperature for 25 years, the thermal insulation performance of rigid polyurethane foam is reduced by less than 3%, and the protective effect of aluminum foil paper on the back is more effective, which ensures that Jiahe panel wall energy-saving system can maintain stable and good thermal insulation and energy-saving effects for a long time under various environmental conditions. 3. The unique design structure of Dalian Jiahe wall energy-saving system completely eliminates the phenomenon of "cold bridge". Effectively avoid indoor humidity, mildew and other phenomena, achieve the effect of heat preservation and insulation, and achieve the purpose of energy saving and consumption reduction. Second, the decorative effect is stronger. 1. The outer surface of Dalian Jiahe board can be pressed into various textures by special technology, with diverse and vivid patterns and rich colors, which can meet different architectural styles. While beautifying the city, it also greatly improves the taste of architecture and blends with nature. 2. polyester paint layer and fluorocarbon layer with high weatherability are used on the surface of Dalian Jiahe board, which has excellent weatherability, corrosion resistance, acid and alkali resistance and self-cleaning, and can ensure the beautiful effect of building facade for a long time. 3. The unique technological structure and technology of Jiahe Board can meet the design requirements of different aesthetic standards and fully bring different levels of visual enjoyment. Third, the construction is simpler. 1. The installation system of Dalian Jiahe Plate adopts dry hanging method, and relevant special fittings are used. The construction process is simple, and there is no need for complicated pretreatment of the external surface of the building. Because it is not affected by the seasonal environment, the construction period is greatly shortened. 2. The construction process is dust-free and noise-free, occupying a small space, and does not produce construction waste, especially in the energy-saving transformation of existing buildings, which will not have any impact on the lives and work of residents. Fourth, the cost performance is better 1. The use of thermal insulation materials should not only consider the thermal conductivity, but also measure the weight of different thermal insulation materials when they reach the same thermal resistance. The thicker the insulation material, the more inconvenient the construction, the larger the volume and the more structural load, which indirectly leads to the increase in cost. Jiahe board is light in weight, reducing the load of wall structure, and combining with the air layer in the system in various ways to achieve double energy-saving effect, which can effectively meet the energy-saving requirements of different regions. 2. Dalian Jiahe Board has a long service life because its surface layer is a metal surface layer, which can effectively prevent large-scale soil erosion caused by brick burning and quarrying, without subsequent phenomena such as falling off, bulging and cracking, and without environmental pollution caused by radioactive substances such as tiles, stones and curtain walls. It is a new building material with safety, environmental protection, green energy saving and long-term benefit to human society.
