PVC kugadzirisa rubatsiro ndeye thermoplastic graft polymer inowanikwa kubva ku polymerization yemethyl methacrylate uye acrylate kuburikidza nembeu lotion. Inonyanya kushandiswa kugadzirisa uye kugadzirwa kwePVC zvinhu. Iyo ine mhedzisiro yakanaka pakuvandudza kukanganisa kwemaitiro ePVC zvinhu. Inogona kugadzirira akawanda-nhanho polymerization nzira uchishandisa mbeu lotion polymerization, kusanganisira yechinyakare lotion polymerization uye core shell lotion polymerization. Kubatsira kwayo kuri mukukwanisa kudzora kuumbwa, saizi, ukobvu hwegoko, chiyero chegoko kune core radius, mashandiro epamusoro, nezvimwe zvezvimedu zvinoenderana nezvinodiwa zvakasiyana panguva yekuita synthesis reaction process, uye inokonzeresa saizi yekugovera yakaenzana. .
Iwo makuru ezvigadzirwa zvePVC kugadzirisa aids ndeye acrylic esters uye methyl methacrylate. Mukugadzirwa chaiko, acrylate inowanzoita polymerized nemamwe mamonomers (senge styrene, acrylonitrile, zvichingodaro) kuburikidza nelotion kuti igadzire polima ine yakaderera girazi tembiricha yekuchinja, kureva, musimboti une elastomer zvimiro, uyezve graft copolymerized nemethyl methacrylate. , styrene, nezvimwewo kugadzira polima ine core shell structure. Iyo yakasimba yemukati yeiyi lotion polymerized lotion inowanzoita 45% ± 3%, uye mafuta ekuzora anoomeswa uye anopera simba kuita kuti mvura irimo yechigadzirwa isadarike 1% (chikamu chemass) kuwana zvigadzirwa zvehupfu chena.
Core shell lotion polymerization ndiyo musimboti weACR resin kugadzira tekinoroji. Iyo yakakosha ganda chimiro cheACR inogona kukamurwa kuita mhando nhatu: yakaoma musimboti yakapfava ganda chimiro, yakapfava musimboti yakaoma ganda chimiro, uye yakaoma yakapfava yakaoma-matatu-layer chimiro. Nekudaro, iwo makuru akasiyana ari kutengeswa pamusika "soft core hard shell structure". ACR resin ane chimiro ichi ane kuita kwakanaka uye anoshandiswa zvakanyanya. Iyo core shell lotion polymerization ye "soft core hard shell structure" inzira iyo hard monomer inobatanidzwa pambeu yezvakapfava latex particles inoumbwa nedanho rekutanga re lotion polymerization. Rudzi uye chiyero cheemulsifiers, core-shell ratio, shell monomer feeding nzira, crosslinking degree yembeu latex particles (rubber core), saizi yembeu, uye mhando uye dosage ye crosslinking agent zvese zvine chekuita chakakosha pane iyo core-shell chimiro. yeACR latex particles uye yekupedzisira chigadzirwa kuita kweACR.
