The Weifang Yaxing Group Co., Ltd. chlorinated polyethylene (CPE) production technology and equipment development projects have recently passed expert appraisal. Experts believe that the software package has independent intellectual property rights, short device flow, low energy consumption, high degree of automation, good product quality, and the overall technology has reached the international advanced level.
It is understood that at the end of the 1980s, Weifang Yaxing Group Co., Ltd. introduced Hoechst's technology to build the first domestic CPE device, and bought off Hoechst CPE special technology. After more than 10 years of continuous development and innovation, it has carried out five large-scale technological transformations. Yaxing 'CPE production technology and equipment development' has achieved a major breakthrough, achieving large-scale equipment, product serialization, production automation, and a new CPE. Complete sets of technology and supporting large-scale equipment.
Its major innovations include the establishment of a new aqueous reaction system with hydrochloric acid and various additives as media, and the ability to flexibly develop new market demands by adjusting reaction medium concentration, dispersant system and initiator ratio and other process parameters. Products, currently CPE varieties have been developed from 5 to 17; the volume of chlorination reactor, one of the most important and highest-tech equipment in the CPE production process, has been increased to 40 cubic meters, which has solved the long-standing existence of China. The problem of low single-pot reactor yield is remarkable in energy saving and consumption reduction; the unique structure of separate stirrer, new pot temperature measurement system, enamel monitoring system, etc. are successfully designed, and it is important for filters, centrifuges, dryers, exhaust scrubbers, etc. The key auxiliary equipment has undergone a comprehensive renovation and transformation, forming a complete large-scale CPE production system with independent intellectual property rights; independent development of successful control software for the new reaction system, for the first time in the country to achieve raw material preparation, reaction system adjustment, chlorination, filtration The process control of the seven units of separation, dry grinding, coating, and waste water treatment is the core part of the process. - controlling the chlorination reaction product may be a package formulation, process parameters adjusted according to the production process more stable, and better product quality.
