Marka la soo bandhigo monomer copolymerization ee silsiladda ugu weyn ee vinyl chloride, polymer cusub oo ka kooban laba monomer ah ayaa la helay, kaas oo loo yaqaan copolymer.Noocyada ugu waaweyn iyo guryaha copolymers of vinyl chloride iyo monomers kale waa sida soo socota:
(1) vinyl chloride vinyl acetate copolymer: soo bandhigida vinyl acetate monomer waxay ciyaari kartaa doorka caagagga guud, taas oo ah, waxa loogu yeero "ballaarinta gudaha", taas oo ka fogaan karta uumiga, socdaalka, soo saarista iyo cilladaha kale ee caagagga guud. , iyo sidoo kale hoos u dhigi kartaa viscosity dhalaalay, yaraynaysaa heerkulka processing iyo hagaajinta waxqabadka processing.Guud ahaan, waxa ku jira vinyl acetate ee kobolymer-ka waa 3 ~ 14%.
Khasaaraha ugu weyn ee vinyl chloride vinyl acetate copolymer waa hoos u dhigida xoogga jilicsanaanta, heerkulka qallafsanaanta kulaylka, caabbinta xirashada, xasilloonida kiimikada iyo xasilloonida kulaylka.
⑵ vinyl chloride vinylidene chloride copolymer: balaastiga, heerkulka jilcinta, milanka iyo balaastiga intramolecular ee kopolimerkan asal ahaan waxa ay la mid yihiin kan vinyl chloride vinyl acetate copolymer.Waxaa lagu gartaa gudbinta biyaha hooseeya iyo gaaska, milanka sare ee dareeraha ketone, iyo iska caabinta milanka aromatics, sidaas darteed si wax ku ool ah ayaa loo isticmaali karaa daaha.Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa in lagu sameeyo filimo yar yar.Sababtoo ah caabbinta kulaylka liidata iyo xasilloonida iftiinka marka la barbar dhigo vinyl chloride vinyl acetate copolymer, iyo qiimaha monomer sare, looma isticmaalo sida vinyl chloride vinyl acetate.
(3) vinyl chloride acrylate copolymer: saamaynta balaastigga gudaha ee kopolymerkan waxa ay la mid tahay ta vinyl chloride vinyl acetate, oo leh xasilooni kulayleed wanaagsan.Waxaa loo isticmaali karaa in lagu soo saaro badeecooyin adag oo jilicsan, iyo hagaajinta hab-socodka, caabbinta saameynta iyo caabbinta qabow.Waxa kale oo loo isticmaali karaa dahaarka, isku xidhka, iwm.
(4) Vinyl chloride maleate copolymer: waxa ku jira maleate ee kopolymerkan waa ilaa 15%, saamaynta balaastikada gudaha waxa ay la mid tahay tan vinyl chloride acrylate.Waxay leedahay hab-socodka wanaagsan.Hoos u dhigista sifooyinka jireed iyo farsamada waa yar yahay, caabbinta kulaylkuna way ka sarraysaa kuwa copolymer-yada guud.
(5) vinyl chloride olefin copolymer: copolymerization of ethylene, propylene iyo monomers kale ee olefin waxay soo saari karaan resins copolymer leh dareere aad u fiican, xasilloonida kulaylka, caabbinta saamaynta, daahfurnaanta, caabbinta kulaylka iyo wixii la mid ah.
Wax ka beddelka xalka isku-dhafka isku-laabashada
Isku-laabashada ku-tallaalidda polymerization falcelinta
Wax ka beddelka iyadoo monomers kale la gelinayo silsiladda dhinaca ee PVC ama silsiladda vinyl chloride ee silsiladda dhinaca ee polymers-ka kala duwan waxaa loo yaqaan 'polymerization reactive reactive graft'.
4. polymerization heerkulka hooseeya
Beddelidda habaynta isku xirka silsiladaha silsiladda ugu weyn ee PVC ama beddelidda habka u dhexeeya silsiladaha PVC waxay la macno tahay beddelidda habka polymerization.Wax ka beddelkan waxa loo yaqaan polymerization-ku-hooseeya.
