product after polyethylene production, accounting for 15% of the total output of plastics. the self-designed pvc production plant inchinawas trial manufactured in jinxi chemical plant of liaoning in 1956. in 1958, the 3kt plant was formally industrialized and the output of 530.9kt was 1984.
pvc was industrialized in the early 30s. from 30s onwards, in a very long time, pvc production has been in the world of plastic content occupied the first. in the late 60s, polyvinyl chloride was replaced by polyvinyl chloride. although pvc plastics are retreated to second, the output of pvc still accounts for more than 1/4 of the total plastic production.
before 60s, the production of mono vinyl chloride was mainly calcium carbide acetylene, because the production of calcium carbide consumed a large amount of electric energy and coke, high cost. at the beginning of the 60s ethylene oxychlorination process for vinyl chloride production industrialization, all countries turn to cheaper oil as raw material. in addition, most of the raw materials of pvc (about 57% wt%) are the associated by-products of chlorine, which are not only rich in raw materials, but also one of the most important products for developing chlor alkali industry and balancing chlorine. as a result, the proportion of pvc in plastic has been reduced, but it still maintains a high growth rate.
pvc plastics products are widely used, but in the middle of 70s, it was recognized that the monomer vinyl chloride (vcm) remained in pvc resin and products is a serious
