New Polycarbonate Polyester Plastic Alloy

The industrialization of polyphenylene ether was a major achievement 7 years ago, and the first addition of the intermediate division to the injection of polyphenylene sulfide in the pilot test was passed in the provincial staff city. The expert team of the appraisal thinks that the pilot plant process is reasonable, the process is smooth, and the quality of the crystals is stable. If the logo already has industrial polyphenylene sulfate production technology with independent intellectual property rights, it fills the domestic gap.

Polyphenylene sulfide is a kind of high-performance special engineering plastics. It has excellent properties such as high temperature and radiation resistance, ablation resistance, and high stability of toughness. It is widely used in electric power machinery manufacturing and other national economic sectors as well as aerospace and other areas.

Zhuhuatuo Industrial Development Co., Ltd. developed a 501 pressurized synthetic plastic-grade polyphenylene sulfide resin device built by Tingjian Co., Ltd., and was sent to the national sample for a heart rate test after 72 tests, with a molecular weight of more than 66,000. 302 reached the leading domestic level. 40. Glass fiber-reinforced pellets were prepared with the resin, and various mechanical properties reached or exceeded the level of similar products of foreign oil companies of the United States and Philips.

The pilot plant uses methylpyrrolidone as a solvent, and the multi-aqueous sodium sulfide is directly fed. After the dehydration within the batch, the chlorobenzene can be added in different increments within a given time, and the stirring speed can be adjusted. Under pressure conditions, polyphenylene sulfide resin polycondensation, vacuum distillation recovery of methyl pyrrolidone solvent and catalyst, novel and practical, its technology at the leading domestic level, close to the same level of technology.

There are five major technological innovations in this experimental study.

In the past, access to national patents was a polyphenylene sulfide production and synthesis process condition control method that creatively used continuous or fractional feeding technology instead of secondary feeding technology, and successfully designed a broadly divided feeding process. Solve the difficulty in controlling the temperature during the process. This control method is easy to realize on the industrialization Maoji dynamic control, thus ensuring the product yield and quality, access to high molecular weight products.

Is a polyphenylene sulfide cattle production solvent and catalyst recovery technology. In particular, the solvent recovery process technology was successfully developed. The technology has the shortest recovery rate in the current sentence. There are new solvent recovery technologies with less impurities. Provides basic data for solvent design and design of process control systems.

The polysulfide dehydration technology in the production of polyphenylene sulfide has successfully used the Li 5 multi-water sodium sulfide azeotropic dewatering technology in the process. The heating and dehydration process is carried out in a polycondensation reactor and the polycondensation reaction temperature rise process. There is no need for special design, saving investment, saving energy in bamboo and reducing costs. Order, on page 30, the amount of material used is increasing year by year. At the same time, we have also made considerable progress in the type of products.

1 It is mainly used for transporting drainage water in urban areas and building drainage water supply. At present, there are more than 600 production companies in Taiwan, and the annual production capacity reaches 500,000 in actual production. 1. The production equipment in Jerusalem is basically domesticated.

Polyethylene pipes are to be used as transportation channels for city gas supply and drainage and building water supply. At present, there are about 150 domestic pipe production enterprises, of which the production of rural water supply and irrigation pipes for agriculture is close to home production. The annual production capacity reaches 450,000, and the actual production volume is about 360,000.

The domestic slush plastic composite bamboo cattle production enterprises are close to 3, and the production line reaches 3, of which more than one of the domestic production lines already accounts for 9, lap welding production lines account for 70 butt welding production lines account for 30, and the production capacity reaches 800 million.

There are nearly 100 domestic cross-linked polyethylene cattle production enterprises, and the production line has reached more than one of them. There are more than one imported production line, and the production capacity reaches 500 million.

At present, there are nearly 100 corpse production enterprises for random copolymer polypropylene pipes in China. There are about 120 production lines in which 1 production line is imported. The production capacity reaches 5.3 billion. Since the beginning of the 21st century, plastic pipes have been used to produce energy. The advantages of less environmental pollution and small product performance are increasingly favored by people, and the attention of the government and customs departments. As a result, plastic pipes will have great market potential in the future in China. Ordering, dipping, 5 new feed Polycarbonate Polyester plastic alloy Plastics-like transparent engineering alloys introduced by Pittsfield, Mass., USA have a series of novel features. The new class of plastics with a class name of 3.1. is polycarbonate. The usual aliphatic polyesters are made by combining them. The latter is an amorphous polyester. Completely mixed with polycarbonate.

3 surgical modified varieties, among them. 7200 uses factory glasses, 7300 is used for electronic consumer products, and 8300 with ultra high impact performance is in consumer products such as home appliances. The first large-scale application of plastic is Dragon 138, an optical company that uses 200 frames of sports glasses.

The company's product director, grasping; said that other transparent resins lack a plastic and has the advantages of toughness and chemical resistance. 7200 plastics also provide a matching internal release agent, 7300 plastic flow rate is higher! Used to make thin-walled components such as computer enclosures.

The high fluidity lowers the filling pressure and gives this plastic the function of in-mold mounting.

In addition, General Electric also introduced two impact modified plastics, namely 70 and 810. These two kinds of frequency material still maintain the transparency and resistance to chemical invasion. They use ten to manufacture communications equipment shell sled laces and outdoor vehicle plates. The heat distortion temperature of 70 is higher, which means it will also occupy a place in the new generation mobile phone cover.
