PVC ipolymer yakaumbwa nemahara radical polymerization yevinyl chloride monomers (VCM) ine ekutanga senge peroxide uye azo macomputer kana pasi pekuita kwechiedza nekupisa.
PVC yaimbove yakakura kwazvo kuburitsa mapurasitiki epasi rose, ndeimwe yemapurasitiki mashanu (PE polyethylene, PP polypropylene, PVC polyvinyl chloride, PS polystyrene, ABS).Inoshandiswa zvakanyanya.Muzvinhu zvekuvaka, zvigadzirwa zvemaindasitiri, zvinodiwa zuva nezuva. , dehwe repasi, tile yepasi, dehwe rekugadzira, pombi, waya uye tambo, firimu rekurongedza, mabhodhoro, furo zvinhu, zvekuisa chisimbiso, fiber uye zvimwe zvinhu zvinoshandiswa zvakanyanya.
PVC yakawanikwa kare muna 1835 muUnited States.PVC yakagadziriswa mukutanga kwe1930s.Kubva kuma1930, kwenguva yakareba, kugadzirwa kwePVC kwakatora nzvimbo yekutanga mukushandiswa kwepurasitiki yenyika.
Maererano zvakasiyana-siyana chikumbiro scope, PVC inogona kukamurwa kuva: mukuru PVC resin, yakakwirira polymerization dhigirii PVC resin, crosslinked PVC resin.According nzira polymerization, PVC inogona kupatsanurwa muzvikamu zvina zvikuru: kuturika PVC, emulsion PVC, yakawanda PVC, mhinduro PVC.
Polyvinyl chloride ine mabhenefiti ekudzoreredza murazvo (flame retardant value inopfuura makumi mana), yakakwirira chemical resistance (kupikisa concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid uye 20% sodium hydroxide), simba rakanaka remuchina uye kuvharisa magetsi. .
Kubva 2016 kusvika 2020, kugadzirwa kwePVC kwepasirese kwanga kuri kuwedzera. Maererano nehuwandu hweBloomberg, kugadzirwa kwePVC yeChina kunotora 42% yekugadzirwa kwepasirese, zvichibva pakuti kugadzirwa kwePVC kwepasi rose kunofungidzirwa kuve 54.31 miriyoni matani muna 2020.
Mumakore achangopfuura, kushandiswa kwePVC indasitiri kwakakura zvishoma nezvishoma.Pasi pemamiriro ekuti mudzimba PVC kugadzirwa uye vhoriyamu yekunze haiwedzere zvakanyanya, kukura kwedhata kwekushandiswa kuri pachena kunokonzeresa kukwidziridzwa kwekudiwa kwakasimba mushure mekuvandudzwa kwehukama pakati pekupa uye kudiwa. Muna 2018, kushandiswa kuri pachena ethylene mumhepo yeChinese yaive 889 miriyoni matani, ichiwedzera ne1.18 miriyoni matani kana 6.66% zvichienzaniswa negore rakapera.Pazvose, simba redu rekugadzira rinopfuura zvakanyanya kudiwa, uye chiyero chekushandiswa kwehuwandu hwekugadzira hachina kukwirira.
Iyo kambani Shin-etsu Chemical Company
Yakavambwa muna 1926, Shin-etsu parizvino ine muzinda kuTokyo uye ine nzvimbo dzekugadzira munyika gumi neina pasi rose.
Shinetsu Chemical yakagadzira yayo yakakura-yemhando yepolymerization tekinoroji uye NONSCALE kugadzirwa kwemaitiro, ichitungamira iyo PVC indasitiri.Zvino, muUnited States, Europe neJapan misika mikuru mitatu, seyakakura kwazvo pasi rose PVC vagadziri vane hukuru hwekugadzira hunyanzvi, yakagadzikana kupihwa kwepamusoro. -zvinhu zvemhando yepamusoro kune nyika.
Shin-yue Chemical ichave nePVC yekugadzira inokwana matani 3.44 miriyoni muna 2020.
