China Petroleum and Natural Gas Co., Ltd.’s first major technology project, the 5,000 tons/year hexene-1 industrialization unit, was completed at Daqing Petrochemical. As of the time of the press release yesterday, Daqing Petrochemical is stepping up preparations for the drive and the installation will begin soon. This set of hexene-1 devices built with the independent technology of Daqing Chemical Research Center will greatly ease the situation in which hexene-1 comonomer in China is heavily dependent on imports, and will change many of China's polyolefin bulk products and high-performance products. Less structural excess production pattern.
It is understood that hexene-1 is an excellent comonomer for polyethylene. The modified polyethylene resin has the advantages of high tensile strength, impact resistance and tear resistance, and is particularly suitable for the production of durable packaging films and agricultural cover films. A number of polyethylene production facilities in China have trial production of perhexene-1 copolymer grade polyethylene products, and the obtained copolymer products have much higher resistance to environmental stress cracking, elongation at break, tensile strength and impact strength than ethylene and 1- Butene copolymer products. The use of hexene-1 instead of 1-butene to produce high-performance linear low-density polyethylene and high-density polyethylene has become a major trend in the development of the polyethylene industry.
Over the years, foreign companies only sell products, do not sell technology, and have long monopolized the Hexene-1 market. The import price of hexene-1 is too expensive, which limits the development and industrialization of China's polyethylene brand, and also affects the upgrading of polyethylene products and the improvement of economic efficiency. The octane-1 and other OL-olefin comonomers are controlled by others, which has restricted the development of China's polyolefin industry.
It is understood that CNPC organized a project to tackle the problem in 1999. The Chemical Research Institute of Daqing Chemical Research Center bravely shouldered the task of this major project. After eight years of active exploration, the center has completed a small pilot study, 100-ton pilot scale amplification and development of technology packages. The main technical indicators have reached or exceeded the level of similar foreign technology. In June 2007, China National Petroleum invested 74 million yuan to set up a special science and technology project, and launched a self-developed 5,000 tons/year hexene-1 industrialized pilot project at Daqing Petrochemical.
At the same time, Daqing Chemical Research Center assumed and completed the construction of a 5,000-ton/year hexene-1 catalyst amplifying device, a catalyst preparation device, and a catalyst evaluation device. It has now produced a qualified catalyst, and formulated and refined the hexene-1 catalyst evaluation standard. And analysis standards. Currently, the center has completed the material balance calculation, separation sequence and energy integration optimization of the 20,000 tons/year hexene-1 process package. Researchers are stepping up the development of the 20,000 tons/year hexene-1 reactor. A complete set of technologies with completely independent intellectual property rights will be formed.
Interior car door handles is a small lever that you pull to release the door's hook from the vehicle frame's latch. There are different forms of inside door handles, though the area where it's mounted remains consistent with most types of vehicles.
The tailgate handle is an external component that triggers the latch mechanism and allows the tailgates to swing open.
Most handles are made of plastic, while some are metal, such as zinc alloy. Further, there are designs offering a mix of both like a plastic bezel and metal lever, or vice versa.
For the car door handle surface finish, there are tons of them available. The list includes the usual chrome-plated, primed, smooth or textured, chrome bezel and colored lever combination, paint to match, satin chrome, and polished.
