Rubatsiro rwekugadzirisa PVC ipolymer ye thermoplastic graft inowanikwa kubva mukupomera kwe methyl methacrylate ne acrylate kuburikidza ne seed lotion. Inonyanya kushandiswa pakugadzira nekugadzira zvinhu zve PVC. Ine mhedzisiro yakanaka pakuvandudza kusimba kwe PVC. Inogona kugadzirira nzira ye multi-step polymerization ichishandisa seed lotion polymerization, kusanganisira polymerization yechinyakare ye lotion uye polymerization ye core shell shell shell. Kubatsira kwayo kuri mukukwanisa kudzora kuumbwa, saizi, ukobvu hwe shell, chiyero che shell ne core radius, hunhu hwepamusoro hwe particles, nezvimwewo zvichienderana nezvinodiwa zvakasiyana panguva ye synthesis reaction process, uye kugoverwa kwe particles size kwakafanana.
Zvinhu zvikuru zvinoshandiswa pakugadzira PVC iacrylic esters uye methyl methacrylate. Mukugadzirwa chaiko, acrylate inowanzo gadzirwa nepolymer nedzimwe monomers (dzakadai sestyrene, acrylonitrile, nezvimwewo) kuburikidza nelotion kuti igadzire polymer ine tembiricha yakaderera yekuchinja kwegirazi, kureva kuti, core ine elastomer properties, uye yozoiswa copolymer nemethyl methacrylate, styrene, nezvimwewo kuti igadzire polymer ine core shell structure. Hunhu hwakasimba hwelotion iyi polymerized lotion hunowanzoita 45% ± 3%, uye lotion inoomeswa uye inobviswa mvura kuti mvura yemuchigadzirwa isapfuure 1% (huremu hwehuwandu) kuti iwane zvigadzirwa zveupfu huchena.
Kugadziriswa kweganda remukati ndiko musimboti wetekinoroji yekugadzira resin yeACR. Chimiro cheganda remukati cheACR chinogona kukamurwa kuita mhando nhatu: chimiro cheganda remukati remukati resimbi, chimiro cheganda remukati resimbi ...
