PVC waa polymer lagu sameeyay polymerization-ka bilaashka ah ee vinyl chloride monomers (VCM) oo leh hindiseyaal sida peroxide iyo xeryahooda azo ama ficilka iftiinka iyo kuleylka.
PVC loo isticmaalo in ay noqon wax soo saarka ugu weyn ee caag ah guud ahaan, waa mid ka mid ah shanta caag ah guud (PE polyetylen, PP polypropylene, PVC polyvinyl chloride, PS polystyrene, ABS) .It's aad u ballaaran loo isticmaalo.In qalabka dhismaha, alaabta warshadaha, daruuri maalin kasta. , Maqaarka sagxadda, foornada sagxadda, maqaar macmal ah, tuubo, fiilada iyo fiilada, filimka baakadaha, dhalooyinka, alaabta xumbo, alaabta wax lagu xiro, fiilooyinka iyo dhinacyada kale ayaa si ballaaran loo isticmaalaa.
PVC waxaa la helay horaantii 1835 gudaha Mareykanka.PVC waxaa la warshadeeyay horraantii 1930-meeyadii. Laga soo bilaabo 1930-meeyadii, muddo dheer, wax soo saarka PVC ayaa qabsaday meesha ugu horeysa ee isticmaalka caagga ah ee adduunka.
Marka loo eego baaxadda codsiga kala duwan, PVC waxaa loo qaybin karaa: xabagta PVC guud, shahaado polymerization sare PVC xabagta, crosslinked PVC resin.Sida hababka polymerization, PVC loo qaybin karaa afar qaybood oo waaweyn: PVC ganaax, emulsion PVC, PVC bulk, xal PVC.
Polyvinyl chloride waxay leedahay faa'iidooyinka ololka dib u dhigista (qiimaha dib u dhiga ololka ee ka badan 40), caabbinta kiimikada sare (iska caabinta hydrochloric acid, 90% sulfuric acid, 60% nitric acid iyo 20% sodium hydroxide), xoog farsamo oo wanaagsan iyo dahaarka korantada .
Laga soo bilaabo 2016 ilaa 2020, wax soo saarka PVC ee caalamiga ah ayaa kor u kacayay.Sida laga soo xigtay tirakoobka Bloomberg, wax soo saarka PVC ee Shiinaha ayaa xisaabiya 42% wax soo saarka caalamiga ah, taas oo ku salaysan wax soo saarka PVC ee caalamiga ah ayaa lagu qiyaasay 54.31 million tons 2020.
Sanadihii la soo dhaafay, isticmaalka warshadaha PVC ayaa si joogto ah u koray.Marka la eego shuruudaha in awoodda wax-soo-saarka PVC ee gudaha iyo mugga soo dejinta aysan si weyn u kordhin, kobaca xogta isticmaalka muuqata ayaa ka badan natiijada kordhinta baahida adag ka dib hagaajinta xiriirka ka dhexeeya sahayda iyo baahida.In 2018, isticmaalka muuqata ee isticmaalka Ethylene jawiga Shiinaha wuxuu ahaa 889 milyan oo tan, oo kordhay 1.18 milyan oo tan ama 6.66% marka la barbar dhigo sannadkii hore. Guud ahaan, awoodda wax-soo-saarkeena ayaa ka sarreysa baahida, iyo heerka isticmaalka ee awoodda wax-soo-saarku maaha mid sarreeya.
Shirkadda Kiimikada Shin-etsu
Waxaa la aasaasay 1926, Shin-etsu hadda waxay xarunteedu tahay Tokyo waxayna leedahay goobo wax soo saar oo ku yaal 14 waddan oo adduunka ah. Waa shirkadda ugu weyn ee wax soo saarka wafer ee adduunka iyo shirkadda ugu weyn ee wax soo saarka PVC.
