ACR yog cov acrylic ester copolymer, uas yog tus tswv cuab-plhaub qauv. Piv nrog PVC, nws qhov hnyav molecular yog siab dua, feem ntau kwv yees li 1-8 lab (qhov nruab nrab hnyav molecular phaus), thiab nws qhov tseeb ntom yog 1.05 g / cm3-1.20 g / cm3. Nws yog tsim los ntawm ntau hom acrylic acid thiab crosslinking tus neeg sawv cev, emulsifier, initiator, molecular weight regulator thiab lwm cov ntaub ntawv nyoos, thiab tom qab ntau lub sij hawm emulsion polymerization, cov dawb micro tsis muaj tshuaj lom thiab tsis muaj tshuaj lom corrosive tau npaj. Piv txwv li, ACR-201 yog kev muab khoom noj los ntawm MMA thiab acrylate; acr-301 yog tsim ntawm MMA thiab EA thiab BA (butyrate methacrylate); ACR-401 yog tsim ntawm MMA thiab Ba, BMA (butyrate methacrylate) thiab EMA (ethyl methacrylate).
Muaj nuj nqi:
Rau qhov tshuab ntawm ACR siv los ua cov khoom ua haujlwm pab hloov kho PVC, qhov kev pom dav dav yog ACR ua raws li PVC resin hais los ntawm cov saw ntev ntev, hloov cov cua sov sab nraud thiab cov khoom txiav shear rau lub cob, txhawb nws txoj kev yaj thiab yas, txo qhov ua haujlwm kub, txhim kho lub yaj lub zog, txhim kho cov tsos kom zoo ntawm cov khoom, thiab tsis txo qhov kev txwv ntawm cov tawv PVC.
Nws muaj zoo sib xws nrog PVC thiab zoo dispersion. Nws yog entangled nrog PVC molecular saw los txhawb PVC melt plasticization, zoo txo PVC yaj ua kev ntsuas kub, thiab txhim kho cov weatherability ntawm cov khoom ntawm lub hauv paus ntawm kev txuag hluav taws xob me;
2. Nws tuaj yeem hloov pauv cov kev coj ua tsis zoo ntawm cov khoom siv PVC, txhim kho cov npliag ntawm PVC cov khoom, ua kom yooj yim rau extrude thiab xyuas kom ruaj khov ntawm kev ua haujlwm ntev;
3. Nws tuaj yeem txhim kho lub zog yaj ntawm PVC cov ntaub ntawv, tsis txhob yaj lub siab, daws cov teeb meem saum npoo xws li tawv nqaij shark, thiab txhim kho lub sab hauv kom zoo nkauj thiab zoo nkauj;
4. Nws tuaj yeem tiv thaiv kom tsis txhob muaj qhov cuam tshuam thiab txaus nti tshwm sim los ntawm extrusion thiab txhaj tshuaj molding, thiab zoo tiv thaiv cov teeb meem saum npoo xws li ripple thiab nees txaij hla;
5. Nws tuaj yeem txhim kho lub ntsej muag kom zoo nkauj ntawm cov khoom, vim hais tias cov yas tsis sib thooj, tib lub sijhawm, nws tuaj yeem pab txhim kho lub zog tensile, cuam tshuam lub zog, elongation thaum tawg thiab lwm yam cuab yeej muaj zog ntawm cov khoom;
6. Nws tuaj yeem txo qhov kev txo qis ntawm ntau yam sib ntxiv xws li stabilizer, xim thiab cov hmoov calcium nyob rau saum npoo ntawm PVC cov khoom lag luam.
7. Lub tshuab foaming tuaj yeem hloov kho lub cell ceev thiab qhov loj me, zoo heev txhim kho lub zog ntawm lub zog ntawm cov khoom siv PVC, zoo qhwv cov roj npuas foaming, tsim cov txheej txheem zoo nkauj honeycomb qauv, tiv thaiv cov roj ntawm kev khiav, thiab txo qhov ntom ntawm cov khoom;
8. Zoo hlau exfoliation, vim nws belongs rau cov ntaub ntawv polymer, yuav tsis ua rau nag lossis daus thiab lwm yam teeb meem xws li roj nplua nyeem.
9. Txhim kho qhov ua tau zoo dua qub ntawm PVC cov khoom lag luam, xws li cov lus muaj zog, lub zog tensile, cuam tshuam lub zog thiab elongation thaum tawg
10. Nws tuaj yeem tiv thaiv qhov tsis zoo ntawm qhov chaw xws li nyiaj xaim hlau ua los ntawm lub siab hloov thiab ntws caws pliav thaum lub sij hawm extrusion thiab txhaj tshuaj molding.
