ACR ua cov khoom siv hauv PVC yuav ua lub luag haujlwm zoo li cas, ACR cov txheej txheem pabcuam tuaj yeem txhawb nqa cov txheej txheem plasticisation, tsuas yog plasticization ntawm cov khoom zoo thiab cov khoom siv zoo, thiaj li tsim tau cov khoom zoo thiab cov khoom siv ntawm cov khoom siv PVC, vim yog cov khoom siv hauv PVC. muaj cov yam ntxwv hauv qab no, ACR kev pab cuam tuaj yeem ua rau PVC nrog kev txhawb nqa ntawm plasticization muaj nuj nqi.
Cov yam ntxwv ntawm ACR processing aids yog:
1.Lub melting kub yog qis dua PVC, ACR ua pab yaj ua ntej PVC hauv cov txheej txheem.
2.Vim nws zoo compatibility nrog PVC, nws muaj peev xwm lo PVC hais tom qab melting thaum lub sij hawm ua, nce kev sib txhuam sab hauv, txhim kho shear torque, ua kom sov sab hauv, ua kom kub tis nyob rau hauv cov khoom uniformly, thiab cov qib ntawm plastification yog uniform, uas. txhawb nqa cov txheej txheem plastification ntawm PVC cov ntaub ntawv.
3.Processing aids muaj qhov hnyav molecular loj txaus los ua kom cov yaj viscosity (los yog lub zog) thaum lub sij hawm ua, ua kom cov yaj siab, tiv thaiv qhov tshwm sim ntawm cov khoom slippage, yog li ua rau cov shear torque, kom lub tshav kub ntawm kev sib txhuam ntawm cov yaj thiab Cov hlau saum npoo nce siab heev, txhawb kev sib xyaw ntawm kev sib xyaw thiab qib ntawm plasticisation ntawm PVC sib tov.
ACR ua cov khoom siv yog tsim los ntawm kev sib txuas thev naus laus zis polymerization ntawm methyl methacrylate hauv alkyl propionate elastomers, nrog "core-plhaub" qauv. Lub "core" yog ib yam ntawm acrylic roj hmab polymer nrog tsawg degree ntawm cross-linking, thiab "plhaub" yog methyl methacrylate nplaum polymer nrog zoo compatibility nrog PVC.
Nws yog dav siv nyob rau hauv PVC cov khoom nyob rau hauv Tuam Tshoj, thiab kev ua hom ACR yog tsuas yog siv los txhim kho cov kev ua tau zoo ntawm PVC, uas yog feem ntau generated los ntawm copolymerisation ntawm methyl methacrylate nrog methacrylate esters thiab acrylate esters.
PVC hom, tab sis PVC resin nws tus kheej mus rau lub tshav kub thiab shear hloov yog tsis muaj zog, qhov tsim ntawm cov yaj tsis zoo li qub, ACR hloov kho, tuaj yeem txhim kho cov PVC, khoom nto gloss thiab lwm yam ntxwv.
Kev ua tau zoo ntawm cov khoom siv yas thiab cov khoom siv ua haujlwm muaj txiaj ntsig zoo nrog rau kev tsim cov khoom siv high-tech yas muaj qhov zoo los pab txhim kho nws cov kev ua tau zoo, thiab tau dhau los ua cov khoom siv dav dav. Ntawm lawv, cov khoom siv yas tau raug txhawb nqa, thiab ntau thiab ntau hom kev txhim kho cov khoom siv tau yooj yim dua.
