How to use sodium silicate?

Water glass Water glass, commonly known as "sodium silicate", is a metal silicate substance, which is composed of alkali metal oxides and silicon dioxide and is easily soluble in water. Sodium silicate solution is commonly used in building engineering. Its chemical formula is Na2O nSiO2. Also known as water glass. It is a kind of water-soluble sodium silicate, the simplest chemical formula is Na2SiO3, and the actual composition is complicated. It is a mixture of various sodium silicates, and its chemical formula should be mNa2O nSiO2. Pure Na2SiO3 is a colorless orthorhombic crystal with melting point of 1088℃. Na2SiO3 5H2O pentahydrate is a white triclinic crystal with a melting point of 72.2℃ and a density of 1.749 g/cm3. Water loss at 100℃. Pure Na2SiO3 is solid, and the production method is as follows: adding Na2CO2 or Na2SO4 into quartz sand or quartzite powder, melting in a glass furnace, and obtaining solid water glass at the temperature of 1300- 1400 degrees. Solid sodium silicate is dissolved in water in a steamer with a pressure of 0.3-0.4 MPa, showing a viscous sodium silicate solution.

How to use glass water correctly? How to use glass water? How to use glass water

Last time, I introduced the functions and types of glass water for automobiles. At present, the quality of automobile glass water on the market is mixed, and the price difference is quite prominent. So, how do consumers correctly choose glass water for automobiles? This will be the problem we will discuss today.

According to auto parts experts, auto glass water is generally divided into 0℃ glass water used in summer and -20℃ and -35℃ glass water used in winter. Its main function is to effectively clean the dust and stains on the automobile windshield, and quickly remove shellac, bird droppings, oil stains and foreign frost.

In order to choose the right automobile glass water, we need to make clear the difference between good and bad automobile glass water.

High-quality automobile glass water is made of deionized water and various environmental additives, which has the functions of decontamination, drainage, antifreeze, antistatic and anticorrosion. It can effectively remove dust, lubricating oil, gasoline and diesel oil, residual wax polish, gum, bird droppings, shellac on expressway, etc. Rain on the windshield can be quickly dispersed to prevent drivers from blurring the windshield in heavy rain. It can neutralize the charge generated by the friction between the windshield and the wiper and the substances in the air, enhance the conductive effect of the glass surface, resist static electricity, and prevent the charge adsorption dirt from affecting the field of vision. The PH value is always neutral, does not contain various metal ions, and has no corrosive effect on automobile topcoat, rubber and various metals. Rain on the windshield can be quickly dispersed to avoid the windshield from being blurred under heavy rainfall. It can neutralize the charge generated by the friction between the windshield and the wiper and the substances in the air, enhance the conductive effect of the glass surface, resist static electricity, and prevent the charge adsorption dirt from affecting the field of vision. The PH value is always neutral, does not contain various metal ions, and has no corrosive effect on automobile paint, rubber and various metals. It can form a protective film on the windshield, which makes the automobile glass clearer and more transparent, and has no corrosion to the automobile paint surface and no swelling and dissolving effect on rubber.

In winter, the special glass water can also directly dissolve foreign frost at the low temperature of -35℃, and can be quickly smeared on the windshield to keep the glass clear and bright and restore a wide field of vision.

Poor quality glass water often appears precipitation, discoloration, taste change and so on. Because the alcohol content is too high, it will have a bad influence on the automobile paint surface, damage the luster and hardness of the automobile paint surface, and will swell and dissolve the rubber parts and plastic parts in contact, reduce the hardness of these parts and produce color difference. Because the automobile glass water will flow near the air inlet of the air conditioner after cleaning the glass, the volatile smell of the glass water will also enter the cab along the ventilation pipe of the automobile air conditioner, and the harmful smell of the deteriorated and moldy glass water and the glass water made of inferior chemical raw materials will become an invisible killer that harms the health of the owner.

I hope the above information is helpful to you.

Application of sodium silicate in chemical industry

Hello, I have consulted professionals who work in da li Sino-French Water Glass Factory. He said that water glass can be divided into sodium water glass and potassium water glass, commonly known as sodium silicate. Sodium silicate is an aqueous solution of sodium silicate with molecular formulas of Na2O nSiO2 and K2O·nSiOz. Potassium sodium silicate is an aqueous solution of potassium silicate, and its molecular formula is K2O·NSIO 2. Sodium silicate is mainly used in civil engineering. When the engineering technical requirements are high, potassium sodium silicate can also be used. High-quality pure water glass is a colorless and transparent viscous liquid, which is easily soluble in water. When containing impurities, it is light yellow or bluish gray.

The wide application of sodium silicate products makes this industry occupy an important position in the national economy. For example, Zhongfa sodium silicate is located at No.63-2, Yanfeng Industrial Zone, da li, Nanhai, which is the production place. The office is located in Building 3, Phase II of Yanbu Pingbu Market.

Sodium silicate is widely used, covering almost all sectors of the national economy.

In the stone industry, it is used to manufacture silicon-aluminum catalysts for petroleum catalysis and cracking;

In the chemical industry, silica gel, zeolite molecular sieve, precipitated silica and various silicates are the basic raw materials of silicide;

In the light chemical industry, it is an indispensable filler in washing powder and soap, and sodium silicate itself is also an efficient detergent. Citizens use softeners and settling aids for tap water.

In textile industry, it is used for dyeing, bleaching and sizing;

In the construction industry, it is used to manufacture quick-drying cement, acid-resistant cement, waterproof oil, soil curing agent, refractory materials, corrugated board and so on.

In mines, it is used for mineral processing, waterproofing and plugging;

In agriculture, it is used to make silicon fertilizer;

Wood has fire resistance after being soaked in sodium silicate;

Eggs can be preserved for a long time without deterioration after soaking in sodium silicate; High-modulus sodium silicate is an adhesive for paperboard and cartons.

What is the dosage of sodium silicate and the ratio of water?

Sodium silicate is liquid, which is called sodium silicate in the south and sodium silicate in the north. Sodium silicate is commonly known as sodium silicate, and liquid sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid. Solid sodium silicate is a colorless, slightly colored transparent or translucent glass block. Forms are divided into liquid, solid and water quenching. Theoretically, this substance is called "colloid".

Ordinary sodium silicate is a block or granular solid with a slight blue color. After being dissolved at high temperature and high pressure, it is a transparent or translucent viscous liquid with a slight color.

Na2O silica

The ratio of quartz sand to alkali, that is, the molar ratio of SiO2 _ 2 to Na2O, determines the modulus m of sodium silicate, which not only shows the composition of sodium silicate, but also affects its physical and chemical properties, so sodium silicate with different modulus has different uses. Widely used in ordinary casting, precision casting, paper making, ceramics, clay, mineral processing, old soil, washing and many other fields.

Water glass is widely used, covering almost all sectors of the national economy. In the chemical system, it is used to manufacture various silicate products such as silica gel, silica white, zeolite molecular sieve, sodium silicate, silica sol, layered silicon, instant powdered sodium silicate, potassium sodium silicate and so on. It is the basic raw material of silicon compound. In economically developed countries, there are more than 50 kinds of deep-processed products with sodium silicate as raw material, some of which have been applied in high-tech and sophisticated fields; In light industry, it is an indispensable raw material in detergents such as washing powder and soap, and it is also a water softener and settling aid. Used for dyeing, bleaching and sizing in textile industry; Metal preservatives widely used in casting, grinding wheel manufacturing and machinery industry; Used in the construction industry to manufacture quick-drying cement, acid-resistant cement waterproof oil, soil curing agent, refractory materials, etc. Silicon fertilizer can be made in agriculture; In addition, it can also be used as silica-alumina catalyst for petroleum catalytic cracking, filler for soap, adhesive for corrugated paper, metal preservative, water softener, detergent additive, refractory and ceramic raw materials, bleaching and dyeing of textiles, mineral processing in mines, waterproofing, plugging, wood fire prevention, food preservation and preparation of adhesives. The breakdown is as follows:

1. Brush the surface of the material to improve the weather resistance.

After coating or impregnating the material with water glass solution, it can penetrate into cracks and pores, and the cured silica gel can block capillary channels, improve the density and strength of the material, and thus improve the weather resistance of the material. However, sodium silicate should not be used for painting or impregnating gypsum products. Sodium silicate reacts with gypsum to produce sodium sulfate (Na2SO4), which crystallizes and expands in the pores of products, resulting in cracking and damage of gypsum products.

Step 2 reinforce the soil

Sodium silicate and calcium chloride solution are alternately injected into the soil, and the two solutions react quickly to form silica gel and calcium silicate gel, which play the role of cementing and filling pores and improve the strength and bearing capacity of the soil. It is often used to strengthen the foundation of silt, sand and fill, which is called double liquid grouting.

3, preparing a quick-setting waterproof agent

Sodium silicate can be mixed with a variety of alum to make a quick-setting waterproof agent, which can be used for local emergency repair such as plugging and joint filling. The setting speed of this alum waterproof agent ......

How to use "water glass" in waterproof treatment

When you say glass water, it should be sodium silicate. It is called sodium silicate in the south and sodium silicate in the north. Sodium silicate is commonly known as sodium silicate, and liquid sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid. Solid sodium silicate is a colorless, slightly colored transparent or translucent glass block. Forms are divided into liquid, solid and water quenching. Theoretically, this substance is called "colloid".

Toilet waterproof should pay attention to the following points:

In recent years, indoor waterproofing advocates the practice of rigid bottom layer and flexible surface layer, which is a more scientific practice. Especially the newly-built houses. The flexible waterproof layer on that floor is really a new waterproof material produced by the settlement of new buildings (which may crack the rigid waterproof layer).

At present, commonly used: acrylic (flexible and highly elastic) waterproof materials, there are two kinds of powder or paste. The same performance. The structure is simple. All building materials supermarkets sell them.
