Taihua Chemical's chlor-alkali branch company is the backbone producer of domestic calcium carbide polyvinyl chloride (PVC). It has vigorously introduced new technologies to address the quality problems of calcium carbide process PVC products. The current product quality can be completely comparable to that of ethylene-based PVC. On January 4th, the company produced the Luohe brand suspension method universal PVC which won the title of “National Customer Satisfaction Product†in Shanxi Province in 2007.
At present, the domestic PVC production is generally divided into ethylene and calcium carbide. The polyvinyl chloride polyvinyl chloride production device has a large scale, excellent quality and obvious benefits, but its cost is greatly affected by the international oil price, and the conditions for construction are limited. The calcium carbide process PVC produced by coal chemical technology has shown its advantages due to its low production cost. There are more than 100 home appliance stone method PVC manufacturers in the urban areas of the Midwest. Shanxi Province is located inland and has poor oil resources. The development of calcium carbide method PVC is the only realistic choice. Taihua Co., Ltd.'s chlor-alkali branch adhered to the innovation of PVC production technology and adopted DCS distributed control system in its production. Compared with PVC produced by ethylene, the overall technical level has no difference.
In recent years, Taihua's rolling technology and technological innovation have increased the scale of calcium carbide process PVC from the previous 10,000 tons/year to the current 240,000 tons/year. In particular, the company adopts domestic and foreign advanced and applicable technologies to carry out independent innovation and cooperative R&D on the difficult problems existing in domestic calcium carbide PVC production at the high starting point technological transformation of 150,000 tons/year PVC equipment. There have been six innovation technologies. Directly used in production, it has achieved remarkable results in improving the conversion absorption rate of PVC, improving quality and reducing consumption, reducing costs, and safety and environmental protection. The company is also the first domestic company to introduce nanotechnology into the production of PVC, and has the most advanced new production control and design technologies such as domestic calcium carbide process PVC.
