Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ================================= Nanhua Machinery has produced the first set of core equipment for biodegradable plastics. Recently, the first set of 5 key pieces of equipment for PBAT (biodegradable plastic) production, manufactured by Nanjing Chemical Machinery Co., Ltd. (Nanhua Machinery), was installed at a client’s facility in Shandong. This set of equipment has a special structure, especially the final polycondensation tower. Its internal components feature a squirrel-cage design; during operation, the rotor at each end is used to drive the rotation of this squirrel cage. High precision is required for the machining and assembly of its components, with the maximum allowable assembly gap being only 7 to 15 millimeters. They designed and manufactured special tooling to feed the 12-meter-long, 30-ton cage into the casing process without touching or brushing it. They also addressed the complex structure of the pre-polymerization tower and the limited welding areas inside its cylinder ； The high requirements regarding the flatness of the tray plates present significant challenges; all 5 units meet the technical specifications to a high standard. The young team responsible for this project has an average age of 34.6 years. They meet weekly with the various workshops to discuss the manufacturing progress, exchange experiences, and overcome various challenges, thereby accumulating the skills and experience needed to take on more projects related to the manufacturing of biodegradable plastic equipment.
