PVC ndi polima wopangidwa ndi free radical polymerization ya vinyl chloride monomers (VCM) yokhala ndi zoyambitsa monga peroxide ndi mankhwala a azo kapena pansi pa kuwala ndi kutentha.
PVC anali linanena bungwe lalikulu kwambiri padziko lonse wa mapulasitiki ambiri, ndi imodzi mwa mapulasitiki asanu ambiri (Pe polyethylene, PP polypropylene, PVC polyvinyl kolorayidi, PS polystyrene, ABS) . , zikopa pansi, matailosi pansi, chikopa yokumba, chitoliro, waya ndi chingwe, ma CD filimu, mabotolo, thovu zipangizo, kusindikiza zipangizo, ulusi ndi mbali zina amagwiritsidwa ntchito kwambiri.
PVC idapezeka koyambirira kwa 1835 ku United States.PVC inali mafakitale kumayambiriro kwa zaka za m'ma 1930. Kuyambira zaka za m'ma 1930, kwa nthawi yaitali, kupanga PVC kwakhala pamalo oyamba pakugwiritsa ntchito pulasitiki padziko lapansi.
Malinga ndi kukula kwa ntchito zosiyanasiyana, PVC akhoza kugawidwa mu: ambiri PVC utomoni, mkulu polymerization digiri PVC utomoni, crosslinked PVC resin.Malinga ndi njira polymerization, PVC akhoza kugawidwa m'magulu anayi: kuyimitsidwa PVC, emulsion PVC, chochuluka PVC, njira PVC.
Polyvinyl kolorayidi ali ndi ubwino wa flame retardant (lawi retardant mtengo woposa 40), mkulu mankhwala kukana (kukana anaikira hydrochloric acid, 90% sulfuric acid, 60% nitric asidi ndi 20% sodium hydroxide), zabwino makina mphamvu ndi kutchinjiriza magetsi. .
Kuchokera mu 2016 mpaka 2020, kupanga PVC padziko lonse kunali kukwera.Malinga ndi ziwerengero za Bloomberg, kupanga PVC ku China kumapanga 42% ya kupanga padziko lonse lapansi, kutengera zomwe kupanga PVC padziko lonse lapansi kukuyembekezeka kukhala matani 54.31 miliyoni mu 2020.
M'zaka zaposachedwa, kugwiritsidwa ntchito kwa makampani a PVC kwakula pang'onopang'ono.Mkhalidwe woti mphamvu zopanga zapakhomo za PVC ndi kuchuluka kwa zolowa sizikuchulukirachulukira, kukula kwa data pakugwiritsa ntchito komwe kukuwoneka kumakhala chifukwa chakukula kwa kufunikira kokhazikika pambuyo pakusintha kwa ubale pakati pa kupezeka ndi kufunikira. ethylene mu chikhalidwe cha Chitchaina anali matani 889 miliyoni, akuwonjezeka ndi matani 1.18 miliyoni kapena 6.66% poyerekeza ndi chaka chathachi.
Malingaliro a kampani Shin-etsu Chemical Company
Yakhazikitsidwa mu 1926, Shin-etsu tsopano ili ku Tokyo ndipo ili ndi malo opangira maiko 14 padziko lonse lapansi.
Shinetsu Chemical yapanga luso lake lalikulu la polymerization ndi kupanga NONSCALE, kutsogolera PVC industry.Now, ku United States, Europe ndi Japan misika ikuluikulu itatu, monga opanga ma PVC akuluakulu padziko lonse lapansi okhala ndi mphamvu yayikulu yopanga, kukhazikika kokhazikika kwapamwamba. -zinthu zabwino kudziko lapansi.
Shin-yue Chemical idzakhala ndi mphamvu yopanga PVC yokwana matani pafupifupi 3.44 miliyoni mu 2020.

2. Occidental Petroleum Corporation
Occidental Petroleum Corporation ndi kampani yofufuza mafuta ndi gasi yochokera ku Houston yomwe ikugwira ntchito ku United States, Middle East, ndi South America. Kampaniyi imagwira ntchito m'magawo atatu: Mafuta ndi Gasi, Chemicals, Midstream ndi Marketing.
Makampani opanga mankhwala amapanga utomoni wa polyvinyl chloride (PVC), chlorine ndi sodium hydroxide (caustic soda) yamapulasitiki, mankhwala ndi mankhwala opangira madzi.

3.
Ineos Group Limited ndi kampani yapadziko lonse lapansi yamankhwala.Ineos imapanga ndikugulitsa zinthu zambiri za petrochemical, Ineos imapereka zinthu zambiri za PVC extrusion ndi kuumba jekeseni m'makalasi ambiri, zomangamanga zamapulogalamu, magalimoto, zamankhwala, zida zogwirira ntchito ndi mafakitale onyamula. padziko lonse lapansi.
Inovyn ndi mgwirizano wa vinyl chloride resin pakati pa Ineos ndi Solvay.Inovyn idzayang'ana kwambiri chuma cha Solvay ndi Ineos pamakampani onse a vinyl chloride ku Europe - polyvinyl chloride (PVC), caustic soda ndi zotumphukira za chlorine.

4.Westlake Chemistry
Westlake Corporation, yomwe idakhazikitsidwa mu 1986 ndipo ili ku Houston, Texas, ndi opanga mayiko osiyanasiyana komanso ogulitsa mafuta a petrochemical ndi zomangamanga.
Westlake Chemical inapeza wopanga PVC waku Germany Vinnolit mu 2014 ndi Axiall pa Ogasiti 31, 2016. Kampani yophatikizidwa idakhala yachitatu yopanga chlor-alkali yopanga komanso yachiwiri yopanga polyvinyl chloride (PVC) ku North America.

5. Mitsui Chemical
Mitsui Chemical ndi imodzi mwamakampani akuluakulu opanga mankhwala ku Japan.Yakhazikitsidwa mu 1892, ili ku Tokyo.The kampani makamaka chinkhoswe mu zofunika petrochemical zopangira, kupanga CHIKWANGWANI zopangira, mankhwala zofunika, utomoni kupanga, mankhwala, mankhwala ntchito, mankhwala abwino, malayisensi ndi mabizinesi ena.
Mitsui Chemical amagulitsa utomoni wa PVC, plasticizer ndi PVC zosinthidwa ku Japan ndi kunja, amafufuza mwachangu misika yatsopano, ndikukulitsa bizinesi nthawi zonse.
