Ka ho hlahisa monomerization ea eona ka har'a ketane e kholo ea vinyl chloride, ho fumanoa polima e ncha e nang le lihokelo tse peli tsa monomer, e bitsoang copolymer.Mefuta e ka sehloohong le thepa ea li-copolymers tsa vinyl chloride le li-monomers tse ling ke tse latelang:
(1) vinyl chloride vinyl acetate copolymer: ho kenyelletsoa ha vinyl acetate monomer ho ka bapala karolo ea polasetiki e akaretsang, ke hore, seo ho thoeng ke "plasticization ea ka hare", e ka qobang ho tsoa mouoane, ho falla, ho ntšoa le mefokolo e meng ea li-plasticizers ka kakaretso. , hape e ka fokotsa viscosity e qhibilihang, ea fokotsa mocheso oa ho sebetsa le ho ntlafatsa ts'ebetso ea ts'ebetso.Ka kakaretso, litaba tsa vinyl acetate ka copolymer ke 3 ~ 14%.
Mathata a ka sehloohong a vinyl chloride vinyl acetate copolymer ke ho fokotseha ha matla a tsitsitseng, mocheso oa mocheso oa mocheso, ho hanyetsa ho roala, botsitso ba lik'hemik'hale le botsitso ba mocheso.
⑵ vinyl chloride vinylidene chloride copolymer: polasetiki, mocheso o nolofatsang, solubility le intramolecular plasticization ea copolymer ena ha e le hantle li tšoana le tsa vinyl chloride vinyl acetate copolymer.E khetholloa ke phetisetso ea metsi a tlase le khase, ho qhibiliha ho hoholo ha li-ketone solvents, le ho hanyetsa ho hlapolloa ha aromatics, kahoo e ka sebelisoa ka katleho ho li-coatings.Ho feta moo, e boetse e sebelisetsoa ho etsa lifilimi tse fokolang.Ka lebaka la ho hanyetsa mocheso o fokolang le botsitso bo bobebe ha bo bapisoa le vinyl chloride vinyl acetate copolymer, le litšenyehelo tse phahameng tsa monomer, ha e sebelisoe haholo e le vinyl chloride vinyl acetate.
(3) vinyl chloride acrylate copolymer: phello ea ka hare ea polasetiki ea copolymer ena e lekana le ea vinyl chloride vinyl acetate, e nang le botsitso bo botle ba mocheso.E ka sebelisoa ho etsa lihlahisoa tse thata le tse bonolo, le ho ntlafatsa ts'ebetso, ho hanyetsa tšusumetso le ho hanyetsa serame.E ka boela ea sebelisoa bakeng sa ho roala, ho kopanya, joalo-joalo.
(4) vinyl chloride maleate copolymer: litaba tsa maleate ho copolymer ena li ka bang 15%, 'me phello ea ka hare ea polasetiki e tšoana le ea vinyl chloride acrylate.E na le ts'ebetso e ntle.Ho fokotseha ha thepa ea 'mele le ea mechine e nyenyane,' me ho hanyetsa mocheso ho phahame ho feta li-copolymers tse tloaelehileng.
(5) vinyl chloride olefin copolymer: copolymerization ea ethylene, propylene le tse ling tse olefin monomers ka hlahisa li-copolymer resins ka mokelikeli o babatsehang, botsitso ba mocheso, ho hanyetsa tšusumetso, ho pepeseha, ho hanyetsa mocheso joalo-joalo.
Phetoho ea tharollo ea ho phutha
Ho phutha graft reactive polymerization
Phetoho ka ho kenya li-monomers tse ling ka har'a ketane e ka thoko ea PVC kapa vinyl chloride ketane ka har'a ketane e ka thoko ea li-polymers tse fapaneng e bitsoa graft reactive polymerization.
4. Polymerization ea mocheso o tlase
Ho fetola tlhophiso ea lihokelo tsa ketane ka har'a ketane e kholo ea PVC kapa ho fetola tlhophiso lipakeng tsa liketane tsa PVC ho bolela ho fetola mokhoa oa polymerization.Phetoho ena e bitsoa polymerization ea mocheso o tlase.
