19G is a newly developed product of Daqing Petrochemical Plastics Factory. After being successfully introduced to the market, 19G has gradually become the trump card of this factory. As of mid-September, the factory had produced a total of 10300 tons of 19G products, with an efficiency of more than 22 million yuan.


Daqing Petrochemical Plastics Plant has 6 sets of production plants, which can produce high-pressure, low-pressure, full-density polyethylene and other products. At present, more than 140 grades of polyethylene resin products have been successfully developed and produced. The polyethylene resin produced by two sets of high-pressure equipment is mainly used for processing agricultural greenhouse film, film and foaming material, and the structure is slightly simple.


In the new production situation, plastic factories change their ideas, take the market demand as the guide, strive to find more benefit growth points, and vigorously develop and produce high-end and efficient new brands of products. The factory organized the personnel of the new product R & D and technical service center to conduct market research in East China, Northeast and Southwest for many times, and found that the price of high-pressure polyethylene resin coating products was high and the market demand was high.The so-called coating material is that in the production of paper cups, raincoats and other products, polyethylene products are "lined" in the inner layer of the products with coating technology, which plays the role of dustproof and waterproof, and is mainly used in the production of medical protective clothing, food, aluminum foil thermal insulation and so on. Daqing Petrochemical Plastics Factory immediately organizes personnel for development and production according to market research information.


Under normal circumstances, the device can carry out pilot-scale simulation production when developing new products, but the high-pressure device in the plastic factory has the characteristics of high temperature and high pressure, and the production conditions are difficult to simulate, so the pilot-scale test can not be carried out. In the face of difficulties, the technical developers of the plastics factory decided to cooperate with Daqing Chemical Research Center, draw lessons from the experience of previous 18G product development, start with the polymerization reaction mechanism, and change the molecular chain structure by adjusting the polymerization reaction parameters. increase the melt strength to meet the user's requirements for processing conditions and product quality.In the process of production, the technicians of Daqing Petrochemical Plastics Plant have successively overcome the difficult problems such as reaction fluctuation and unstable product index, and realized the stable production of the products. Under difficult production conditions, the factory also "narrowed" the process index, adjusting the fluctuation range from plus or minus 0.1 to plus or minus 0.02, making the control of the process index more accurate and the product performance more stable. After continuous improvement and improvement by technicians, the performance of 19G products has become increasingly stable and has finally been successfully introduced to the market.


In order to deeply tap the efficiency of the products, Daqing Petrochemical Plastics Plant also put 19G into internal production to replace the purchased 1C7A as the raw material for the production of three-in-one composite paper bags to further reduce production costs. Up to now, the plastic factory has used 4.7 tons of 19G products in the production of three-in-one composite paper bags, saving 14000 yuan in the cost of purchased materials.
