Asphyxiation Collection i Wuxi has developed a new generation of propylene polymerization reactors. The Powerless Mahua Company successfully researched and developed a new generation of propylene polymerization experts. The experts believe that this product has filled the gaps in China and laid a solid foundation for the integration of China's petrochemical plants and the international advanced level.

Propylene polymerizer is an indispensable key equipment for polypropylene production. It is also widely used in many fields such as chemicals, medicines and dyes. No market power Mahua Company conducted technical research on the new courses of the long cycle, full load and fast section of the propylene polymerization tank, which extended the replacement life of the polymer tank seal packing to more than one and a half years; the stirrer was symmetrical and bidirectional. With the structure, the single-bottle production is lifted by about 15%; the heat exchange device is changed from the finger-type tube to the U-tube, and the heat transfer efficiency is improved by 100%. According to scientific calculations, only one 12m3 polypropylene reactor can be used for one year. Create more than 1 million yuan of efficiency.

The advanced cracking furnace control technology has successfully developed cracking furnace advanced control technology through the identification of the Institute of Automation, East China University of Science and Technology. Recently, the technology passed the expert appraisal organized by relevant departments.

Yuan, and the prospect of popularization and application is very broad.

The melter for polythylene production was recently introduced, and a kind of melt filtration for poly production was successfully developed at Sinopec Nanhua Chemical Machinery Plant.

The melt diver is the key equipment for the production of old slices. It operates under conditions of temperature and pressure separation, and it can be heated, cooled, and driven in a multitude of ways. A slight deviation will directly affect the quality of the poly chip. Therefore, the equipment design and manufacturing requirements are extremely demanding. Nano Chemicals boldly uses a lined stainless steel liner, the outer shell is wrapped with a multi-layer container plate, and the inlet seals and joints are configured so that the melt filter is more secure. Compared with the imported stainless steel equipment, the equipment can save material costs by 60% and increase its strength.

Non-slip degumming and climbing successfully developed A kind of pipe anti-slip rubber seal ring widely used in water pipelines was successfully trial-produced in Hebei Langfang New Rubber General Factory (3531 factory) and it has been applied for national patent.

The inside circumference of the product is evenly distributed with a certain number of metal tooth pieces, and the support steel surround is added, which is used together with the T-shaped apron. Through the reverse saw tooth of the gold tooth block and the conical pinch formed between the pipe fittings, the socket of the pipe fitting can not be moved outwards, thereby playing the role of slipping off. The use of this product can reduce the cost of the library, lift off the safety factor of the paperwork, and thus suffer from the flaws of the construction unit.
