Cov teebmeem ntawm ACR impact modifiers yog dab tsi?

ACR impact modifier yog ib qho acrylic copolymer nrog lub plhaub-core qauv, uas ua ntau lub luag haujlwm tseem ceeb hauv kev ua cov yas xws li PVC.
1. Kev txhim kho kev cuam tshuam
Los ntawm kev ua kom cov kab nyiaj thiab cov hlua khi los ntawm cov txheej txheem elastomer tseem ceeb, lub zog cuam tshuam raug nqus, txhim kho lub zog cuam tshuam ntawm cov khoom (tshwj xeeb tshaj yog nyob rau hauv qhov kub qis); Kev tsim qauv ntawm lub plhaub tseem ceeb tuaj yeem ua rau lub zog cuam tshuam ntau dua 6 zaug thiab tswj tau 90% kev tawv ntawm -40 ℃
2. Kev ua kom zoo dua ntawm kev ua haujlwm
Txhawb kom PVC plasticization, ua kom lub sijhawm ua tiav luv dua, txhim kho kev ntws thiab kev ruaj khov ntawm cov yaj; Txo qhov tshwm sim ntawm kev tawg ntawm cov yaj thiab txhim kho qhov zoo ntawm cov qauv sib txawv.
3. Kev txhim kho kev ua tau zoo tag nrho
Txhim kho qhov du ntawm cov khoom thiab tshem tawm cov qhov tsis zoo xws li ntses qhov muag thiab cov cim ntws; Txhim kho kev tiv thaiv huab cua, kev tiv thaiv cua sov, thiab kev ruaj khov tshuaj lom neeg, tshwj xeeb tshaj yog haum rau cov khoom sab nraum zoov
4. Cov txiaj ntsig tshwj xeeb ntawm daim ntawv thov
Kev sib raug zoo heev nrog PVC, sib npaug zos kom tsis txhob muaj kev sib sau ua ke; Piv rau cov hloov kho xws li CPE, ACR muaj qhov kub thiab txias ua haujlwm dav dua thiab kev hloov kho zoo dua; Pob tshab ACR tuaj yeem tswj tau lub teeb ci ntsa iab tshaj 85% thiab tsim nyog rau cov khoom pob tshab; Tus nqi ntxiv ib txwm yog 0.5-5phr, thiab yuav tsum zam kev sib xyaw ncaj qha nrog cov khoom siv alkaline. Tam sim no, Bangtai Petrochemical ACR tau dhau los ua ib qho ntawm cov hloov kho nyiam rau cov ntaub ntawv PVC tawv, cov kav dej, thiab cov khoom siv yas engineering.
5. Xaiv tus qauv ACR uas tsim nyog
Profile/Yeeb nkab: Cov qauv hnyav molecular siab yog qhov zoo dua, nrog qhov hnyav molecular ntau dua 500000, uas tuaj yeem ua rau lub zog yaj ntau dua 40% thiab ua kom zoo tiv thaiv kev tawg ntawm extrusion yaj; Cov khoom txhaj tshuaj pwm / cov khoom nyias-phab ntsa: Cov qauv hnyav molecular qis yog qhov pom zoo, nrog qhov hnyav molecular ntawm 300000 txog 500000 kom txo qhov viscosity yaj thiab nce qhov ceev ntawm kev sau los ntawm 25% -30%; Cov khoom pob tshab yuav tsum tau ua ke nrog MBS (solubility parameter 9.4-9.5) rau kev siv sib xyaw, nrog lub teeb transmittance ntawm> 85%
