Project introduction:

Chlorinated polyvinyl chloride (CPVC) is a kind of polymer material with excellent comprehensive properties. It is a new material synthesized from PVC and chlorine gas. It can solve the imbalance of chlor-alkali development in China and the low added value of chlorine products, the polyvinyl chloride of the three development problems of excess capacity and severe homogeneity.

The application prospect of CPVC is broad. It is widely used in industry, civil, fire and other fields. At present, the main synthesis process of CPVC is aqueous phase method in China, but this process has high energy and water consumption and will produce a lot of wastewater. Gas-solid synthesis of CPVC is an internationally recognized green technology, with short process flow, clean process without wastewater discharge, low production costs, etc. . But at present, only France has realized the industrialization of CPVC resin by gas-solid phase method. Both Hangzhou electrochemical Group Co. , Ltd and Jiangsu Le&Man Chemical import technology from AKMA .

Xinjiang Tianye United Tsinghua University and Shandong Gaoxin Chemical Co. , Ltd. to set up a laboratory-pilot-pilot-industrial demonstration device innovation platform, the world's first separate gas-solid circulating fluidized bed (Cfb) was creatively developed by process decoupling, and the difficulty of heat removal and easy mixing of materials were overcome by the activation method of domestic ultraviolet lamp, the problem of uneven chlorination. This technological breakthrough with independent intellectual property rights fills the gap of domestic green chlorinated polymers process, and creates a model for the high-quality development of chlor-alkali industry in China.

The project has completed the first set of gas-solid production capacity of 20,000 tons per year around the word. The products have been sold to Shandong, Jiangsu, Chongqing and other places, and they have been highly praised by downstream customers.
