At present, we often refer to the yellow pages as the phone book. At present, almost every city in the world has a telephone book (yellow pages) printed on this paper.

Free Chinese yellow pages, business directory, business guide, consumer guide, etc. What is popular on the internet now can also be regarded as various manifestations of the yellow pages; The Yellow Pages can be released and published to the public in print, CD-ROM, Internet and other forms.

The Yellow Pages 19 was born in the United States at the end of September. At that time, the telephone directory, like the current publications, was printed in white paper. Due to the lack of white paper in a printing factory, it was temporarily changed to yellow paper, but I didn't expect the printed effect to be better than white paper, so I printed it with yellow paper in the future. Other printing houses have followed suit, printing telephone books with yellow paper, and gradually formed a convention. Since then, telephone directories all over the world have been called "yellow pages"

The world's first yellow pages phone book appeared in the United States in 1880, and it has a history of more than 100 years. The Yellow Pages is an international industrial and commercial telephone directory arranged by enterprise nature and product category, which is equivalent to the household registration book of industrial and commercial enterprises in a city or region. The international practice is to print on yellow paper, so it is called yellow pages. At present, we often refer to the yellow pages as the phone book. At present, almost every city in the world has such a telephone book (yellow pages) printed on paper.

Paper media publishes classified advertisements and products in the form of telephone numbers, including simple information such as company address, telephone number, company name, postal code and contact person.

Its disadvantages:

1, users can query step by step according to the index classification, and similar yellow pages can be found in various regions, but it is very inconvenient to query in the face of huge text materials. Basically, the telephone is the main single mode of communication.

2. Traditional yellow pages products are limited by circulation and distribution channels, and the promotion of customers can only be achieved by how much they are distributed and how much they are expanded, so it is impossible to accurately predict the number of visitors.

3. Due to the limitation of publishing and printing time, the update speed is slow and can only be modified in the revision.

4. According to the purchase price of the enterprise, limited by the page size, the capacity of enterprise data is also limited.

Yellow pages used to be paper documents, but now most of them exist in electronic form.

Hoping to solve this problem,

Adopt it, adoption is my motivation,

The service is absolutely satisfactory.

I think some rubber products are sold by a spoonful. I want to ask if rubber products are poisonous. What are the uses? When making rubber products, rubber itself is not toxic, but some components are toxic. Therefore, most factories now use intelligent drug batching systems to avoid direct contact with the human body. When in use, some rubbers in contact with human body have high requirements, from the choice of rubber types (generally silicone rubber and PU) to the use of compounding agents. If it is commonly used, such as tires and sealing rings, it has little to do with the human body. There are also many uses, such as umbrellas, raincoats, wire sheaths, various balls and tires.

What rubber products are there at home? Rubber gasket sealing ring in condom pipeline, mobile phone cover window sealing strip, rubber plate, table tennis bat, rubber band, rubber gloves, rubber tube, basketball and football shoes, etc.

What are the production processes of rubber products? 1. The main raw materials of rubber products are raw rubber, various compounding agents, fibers and metal materials as skeleton materials. The basic production process of rubber products is summarized as follows: process: 1, plastication 2, mixing 3, calendering 4, extrusion 5, molding 6 and vulcanization.

Second, specifically:

The processing technology of rubber is mainly to solve the contradiction between plasticity and elasticity. Through various processing means, elastic rubber is changed into plastic rubber, and various additives are added to make semi-finished products, and then the semi-finished products with plasticity are vulcanized to become rubber products with high elasticity and good physical and mechanical efficiency.

1, production method of rubber

Latexes of rubber trees, rubber grasses and other plants are extracted and processed into an elastic, insulating, water-tight and air-tight material. High elastic polymer compound. It is divided into natural rubber and synthetic rubber. Natural rubber is made from rubber tree, rubber grass and other plants after extracting gum; Synthetic rubber is polymerized from various monomers. Rubber products are widely used in all aspects of industry or life.

2, the processing process

This process includes basic processes such as plastication, mixing, calendering or extrusion, molding, vulcanization, etc. Each process has different requirements for products, and is equipped with several auxiliary operations respectively. In order to add various necessary additives to rubber, it is necessary to plasticate raw rubber to improve its plasticity. Then, carbon black, various rubber additives and rubber are evenly mixed to prepare a rubber compound; Extrude a rubber material into a blank with a certain shape; Then it is combined with calendered textile materials (or metal materials) to form semi-finished products; Finally, the semi-finished product with plasticity is vulcanized to make the final product with high elasticity.

3. For products with high precision requirements, rubber products such as oil seals, O-rings and seals. , trimming, deburring, optional methods include manual trimming, mechanical trimming, and frozen trimming.

Manual trimming: high labor intensity, low efficiency and low qualified rate.

Mechanical trimming: there are mainly punching, grinding wheel trimming and circular knife trimming, which are suitable for specific products with low precision requirements.

Frozen edger: A special frozen edger, whose principle is to make the finished product's burr brittle at low temperature by using liquid nitrogen (LN2), and to remove the burr quickly by using specific frozen particles (small balls) to impact the burr. Frozen trimming has become the mainstream technical standard because of its high efficiency, low cost and wide range of applicable products.
