Single layer and multi layer co extrusion sheet (plate) production line
Modification and application of polycarbonatePolycarbonate (PC) is a kind of polymer containing magnetic acid enzyme in the molecular chain. It is one of the five general engineering plastics: * production and consumption is only second to dry nylon, and it is the third in engineering materials. PC was put into production by Germany first company in 1546, and has been industrialized for more than 40 years. The method of exchange and phosgenation can be used to produce low and medium density tree brain. Phosgene method can be used to produce the products of manufacturer, medium and body protection. PC can be processed by many methods just like other methods. Such as injection molding, extrusion molding, plastic molding and secondary processing. PC is mainly used in electronic and electrical, automobile industry, mechanical industry, medical equipment, packaging materials and other fields, including: 1 optical disc: more than 90% of the optical discs in the market are produced by optical grade PC, and the optical media has accounted for 25% of the PC demand@ Automotive Materials: PC is mainly used in automotive lighting system, instrument panel, defroster, bumper and other fields. In addition, PC materials with good impact resistance and light transmittance are used in almost all automobile lighting systems. 9 building materials: the thermal insulation performance of PC board is 25% higher than that of glass, the impact strength is 250 times of glass, and the weight is only 1 / 2 of glass. In recent years, PC board has been widely used in various shapes of large area lighting roofs and lighting facilities of high-rise buildings. Others can also be used for packaging materials, glasses materials, medical devices, etc.
In recent 10 years, due to the increasing demand of optical media and automobile, PC production has been growing rapidly. In 2006, the total production capacity of PC in the world has reached 380000. GE Plastics and Bayer are the two largest manufacturers, controlling 60% of the world's PC production capacity (36% and 23% respectively). The third manufacturer is Dow Chemical Co., Ltd., which accounts for 11% of the total, and the other manufacturers account for 30%. The global demand for PC will continue to grow at an average annual rate of 8%, the demand in Asia will grow by more than 10%, and the demand in China will grow by 10% ~ 15%. Among them. The demand for PC in the electronics and electrical industry is particularly strong, accounting for about 1 / 3 of the demand in the ancient world.
At present, there are more than 20 sets of main PC devices in the world. In order to meet the demand of the global PC market, all PC suppliers plan to expand their production in the next few years. By 2010, Bayer will invest 6 billion US dollars in Asia; In Thailand, China, India and other places to build and expand PC devices, the PC capacity of matafu in the East will be expanded to 250000 tons, and the second day double ship a device will be built locally. In the new year, the company built a PC combined plant in India, with an initial capacity of 50000 V and a post machine capacity of 100000 v. the company's P capacity in Beitang, Meizhou, USA, will increase from 200000 to 350000 G Merging materials company
Invest 254 million US dollars in Shanghai Qingjing Chemical Industrial Zone, China, to build 200000 c assembly camp and PA (Double Volume 4) assembly and production of makrclan brand P, so as to meet the growing demand, and plan to expand the annual output to 200000 V in 207
By 2006, the total PC production of Baer had exceeded 1.2 million. Buren company had 20 years of experience in building additional PC devices and 100000 new devices in the United States, bringing its total power to 305000. Teiren company had built 50000 C devices in Jiaxing, China. 1g. Dow Mengzhen Baner company (50 / 50 joint venture) increased production and construction by 650000 / unit in Lishui, South Korea. Finished at the end of 2001, producing clibre brand PC of Dow Chemical Company. Mitsubishi Gas Chemical Company (MGC) also plans to invest about US $126 million to build a 100000 1 / PC project in China. Japan chemical company transfers non phosgene PC technology to kamaacprpet company of Russia and builds 65000 tapc units in Kazan. The technology uses (C0 and a) as starting materials. There is no need for phosgene and erjiajiayuan tea agent to produce C. The FC reading unit was built in November 201. Kmmrgm company is the second transferor of Xiangcheng technology. Qimeixu company (a joint venture of Qimei and Asahi Huacheng 9% 10) in Taiwan has built 65000 units in Tainan using this process. Qimeixu company is building a second PC production line in Tainan with a production capacity of 75000 T / 2, It was put into production in 2006. The investment cost of the non phosgene PC plant is lower than that of the conventional PC technology, and the construction investment of the first plant (Tainan) is US $100 million (excluding the patent fee).
