On August 3rd, the reporter learned from Daqing Refining & Chemical Company that the new polypropylene product HA510M, which was successfully developed by the company in May this year, has been widely recognized by domestic and foreign manufacturers in the food packaging industry, and has been exported to Southeast Asia in several batches, becoming a new profit growth point of the company.
Adhering to the business philosophy of reputation first and quality first, Daqing Refining & Chemical Company strictly controls the product quality, runs quality control through every link and every detail of the production process, and is committed to making it a famous brand product of PetroChina with excellent quality, continuously expanding the product market space and improving the economic benefits of enterprises.
"HA510M polypropylene is the fist product in the film material series that the company focuses on. We have to ensure that it can't contain any impurities after being drawn into a film." Zou Chunzhi, a process engineer in the polypropylene production area of the third chemical industry, said.
Faced with this difficulty in quality control, this operation area first ensures the stability of melting index of polymer powder, creating conditions for subsequent extrusion granulation. In the granulation process, the mixing effect of powder and additives is improved, and two measures are taken simultaneously to ensure that the key parameters such as melt finger, bend and fisheye of products are superior to the quality requirements of foreign manufacturers.
