Nekuunza iyo monomer copolymerization mucheni huru yevinyl chloride, polima nyowani ine maviri monomer link inowanikwa, iyo inonzi copolymer.Iwo makuru emhando uye zvimiro zvecopolymers evinyl chloride uye mamwe monomers ndeaya anotevera:
(1) vinyl chloride vinyl acetate copolymer: kuiswa kwevinyl acetate monomer kunogona kuita basa rehuzhinji plasticizer, kureva, iyo inonzi "yemukati plasticization", iyo inogona kudzivirira evaporation, kutama, kudhirowa uye zvimwe zvikanganiso zvegeneral plasticizers. , uye inogonawo kuderedza kunyunguduka viscosity, kuderedza kupisa kwekugadzirisa uye kuvandudza kushanda kwekugadzirisa.Kazhinji, zviri mukati mevinyl acetate mucopolymer ndeye 3 ~ 14%.
Izvo zvakanyanya kuipa kwevinyl chloride vinyl acetate copolymer ndiko kudzikiswa kwesimba rekusimba, tembiricha yekupisa yekupisa, kuramba kupfeka, kugadzikana kwemakemikari uye kugadzikana kwekupisa.
⑵ vinyl chloride vinylidene chloride copolymer: iyo plasticization, kupfavisa tembiricha, solubility uye intramolecular plasticization yeiyi copolymer zvakangofanana neiyo yevinyl chloride vinyl acetate copolymer.Iyo inoratidzirwa nekudzika kwemvura uye gasi transmittance, yakanyanya solubility muketone solvents, uye kuramba kuderedzwa kweanonhuhwirira, saka inogona kunyatso shandiswa mukupfeka.Mukuwedzera, inoshandiswawo kugadzira shrink mafirimu.Nekuda kwekushomeka kwekupisa kwekupisa uye kugadzikana kwechiedza zvichienzaniswa nevinyl chloride vinyl acetate copolymer, uye yakakwirira monomer mutengo, haishandiswe zvakanyanya sevinyl chloride vinyl acetate.
(3) vinyl chloride acrylate copolymer: iyo yemukati plasticizing mhedzisiro yeiyi copolymer yakaenzana neiyo yevinyl chloride vinyl acetate, ine yakanaka yekudziya kugadzikana.Inogona kushandiswa kugadzira yakaoma uye yakapfava zvigadzirwa, uye kugadzirisa processability, kukanganisa kupikisa uye kutonhora kuramba.Inogonawo kushandiswa kugadzira, kubatanidza, nezvimwe.
(4) vinyl chloride maleate copolymer: zvinyorwa zve maleate mune iyi copolymer inenge 15%, uye mukati meplasticizing effect yakafanana neiyo yevinyl chloride acrylate.Iine yakanaka processability.Kuderedzwa kwezvinhu zvemuviri uye zvemagetsi zvidiki, uye kupisa kwekudzivirira kwakakwira kupfuura iyo yeanowanzo copolymers.
(5) vinyl chloride olefin copolymer: copolymerization ye ethylene, propylene uye mamwe maolefin monomers anogona kugadzira copolymer resins ine yakanakisa fluidity, kugadzikana kwekupisa, kukanganisa kupikisa, kujeka, kupisa kupisa uye zvichingodaro.
Kupeta kusanganisa mhinduro kugadzirisa
Folding graft reactive polymerization
Iko kugadziridzwa nekuunza mamwe mamonomers mucheni yepadivi yePVC kana vinyl chloride cheni mukati mengetani yemapolymers epadivi anonzi graft reactive polymerization.
4. Low tembiricha polymerization
Kushandura kurongeka kwemaketani ekubatanidza muketani huru yePVC kana kushandura kurongeka pakati pePVC cheni zvinoreva kushandura nzira yepolymerization.Iyi shanduko inonzi yakaderera-temperature polymerization.
