Polyvinyl chloride

Polyvinyl chloride, PVC, waa polymer uu sameeyay vinyl chloride monomer (VCM) ee peroxide, xeryahooda azo ama habka polymerization ee polymerization xagjirka ah ee iftiinka iyo kulaylka.Ethylene chloride homopolymer iyo vinyl chloride copolymer system waxa loo yaqaan resin vinyl chloride.PVC waxay mar ahaan jirtay wax soo saarka balaastiigga ugu weyn oo si ballaaran loo isticmaalo.Waxaa si ballaaran loo isticmaalaa qalabka dhismaha, alaabta warshadaha, baahida maalinlaha ah, maqaarka sagxadda, leben sagxadda, maqaar macmal ah, alaabta tuubada, fiilada iyo fiilada, filimka baakadaha, dhalooyinka, alaabta xumbo, alaabta wax lagu xiro, fiber iyo dhinacyo kale.Marka loo eego baaxadda kala duwan ee codsiga, PVC waxaa loo qaybin karaa: nooca guud ee PVC, resin PVC polymerization sare, resin PVC iskutallaab ah.Nooca guud ee xabagta PVC waxaa lagu sameeyay polymerization of vinyl chloride monomer iyadoo hoos timaada ficilka bilawga;polymerization sare ee xabagta PVC waxaa loola jeedaa polymerka nidaamka polymerization;iyo xabagta PVC ee isku xidhan waxay ka kooban tahay walax isku xidha oo ka kooban diene iyo polyene ee nidaamka polymerization monomer vinyl chloride.Marka loo eego habka iibka ee ethylene chloride monomer, waxa loo qaybin karaa habka calcium carbide, habka ethylene iyo soo dejinta (EDC, VCM) monomer habka (habka etylen iyo habka monomer dibadda laga keeno waxaa caadi ahaan loo yaqaan habka ethylene).Marka loo eego habka polymerization, PVC waxaa loo qaybin karaa afar qaybood: Habka joojinta PVC, habka emulsion PVC, habka bulk PVC, habka xalalka PVC.Joojinta PVC waa wax-soo-saarka ugu weyn, oo xisaabiya qiyaastii 80% wadarta PVC.Habka joojinta ee PVC waxaa loo qaybiyaa lix nooc: XS-1, XS-2..., XS-6;XJ-1, XJ-2..., XJ-6.Macnaha xaraf kasta ee qaabka: Habka joojinta X;Nooca dabacsan;nooca J-cidhiidhi ah.Sida laga soo xigtay maaddada caagagga, PVC caag ene caag ah inta badan waxaa loo qaybiyaa: ma plasticizer PVC, content caag ah waa 0;PVC adag, maadada balaastikada ah waxay ka yar tahay 10%;PVC-gaab adag, maadada caaga ah ee 10-30%;PVC jilicsan, maadada caaga ah ee 30-70%;polyvinyl
