PVC ke polymer e entsoeng ka polymerization ea mahala ea vinyl chloride monomers (VCM) e nang le li-initiators tse kang peroxide le metsoako ea azo kapa tlas'a ketso ea khanya le mocheso.
PVC e kileng ea e-ba sehlahisoa se seholo ka ho fetisisa lefatšeng sa polasetiki e akaretsang, ke e 'ngoe ea lipolasetiki tse hlano tse akaretsang (PE polyethylene, PP polypropylene, PVC polyvinyl chloride, PS polystyrene, ABS).E sebelisoa haholo.Ka thepa ea mohaho, lihlahisoa tsa indasteri, litlhoko tsa letsatsi le letsatsi , letlalo la fatše, tile ea fatše, letlalo la maiketsetso, phala, terata le cable, filimi ea ho paka, libotlolo, lisebelisoa tsa foam, thepa ea ho tiisa, likhoele le likarolo tse ling li sebelisoa haholo.
PVC e ile ea sibolloa khale ka 1835 United States.PVC e ne e entsoe ka indasteri mathoasong a lilemo tsa bo-1930. Ho tloha lilemong tsa bo-1930, ka nako e telele, tlhahiso ea PVC e nkile sebaka sa pele sa tšebeliso ea polasetiki lefatšeng.
Ho ea ka mefuta e fapaneng ea kopo, PVC e ka aroloa ka: kakaretso ea PVC resin, polymerization degree PVC resin, crosslinked PVC resin. Ho ea ka mekhoa ea polymerization, PVC e ka aroloa ka mekhahlelo e mene e meholo: PVC e emisitsoeng, PVC ea emulsion, PVC e ngata, tharollo PVC.
Polyvinyl chloride e na le melemo ea ho thibela lelakabe (boleng bo thibelang lelakabe ho feta 40), khanyetso e phahameng ea lik'hemik'hale (ho hanana le concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid le 20% sodium hydroxide), matla a matle a mochini le ho kenella ka motlakase. .
Ho tloha 2016 ho isa 2020, tlhahiso ea PVC ea lefats'e e ne e ntse e eketseha. Ho ea ka lipalo-palo tsa Bloomberg, tlhahiso ea PVC ea Chaena e etsa karolo ea 42% ea tlhahiso ea lefats'e, ho latela hore tlhahiso ea PVC ea lefats'e e hakanngoa hore e ka ba lithane tse limilione tse 54.31 ka 2020.
Lilemong tsa morao tjena, tšebeliso ea indasteri ea PVC e ntse e eketseha butle-butle.Tlas'a boemo ba hore matla a tlhahiso ea PVC ea malapeng le bophahamo ba thepa ha e eketsehe haholo, kholo ea data ea tšebeliso e bonahalang e bakoa ke ho eketseha ha tlhokahalo e thata ka mor'a ho ntlafatsa kamano pakeng tsa phepelo le tlhokahalo. ethylene sebakeng sa Sechaena e ne e le lithane tse limilione tse 889, e eketseha ka lithane tse limilione tse 1.18 kapa 6.66% ha e bapisoa le selemo se fetileng.
Khampani ea Lik'hemik'hale ea Shin-etsu
E thehiloe ka 1926, Shin-etsu e se e le ntlo-khōlō Tokyo 'me e na le libaka tsa tlhahiso linaheng tse 14 ho pota lefatše.
Shinetsu Chemical e thehile theknoloji ea eona e kholo ea polymerization le ts'ebetso ea tlhahiso ea NONSCALE, e etellang pele indasteri ea PVC. Hona joale, United States, Europe le Japane limmaraka tse tharo tse kholo, e le baetsi ba PVC ba kholo ka ho fetisisa lefatšeng ba nang le matla a maholo a tlhahiso, phepelo e tsitsitseng ea lihlahisoa tse phahameng. -masebediswa a boleng ho lefatshe.
Shin-yue Chemical e tla ba le tlhahiso ea PVC ea lithane tse ka bang limilione tse 3.44 ka 2020.
