Cov yam ntxwv ntawm ACR cov txheej txheem pab muaj raws li hauv qab no
1. Qhov kub yaj ntawm ACR qis dua li ntawm PVC, thiab ACR melts ua ntej PVC.
2. Vim tias nws zoo sib xws nrog PVC, nws tuaj yeem ua raws PVC cov khoom tom qab yaj thaum lub sijhawm ua haujlwm, nce kev sib txhuam sab hauv, ua kom lub zog sib tsoo thiab ua kom muaj cua sov sab hauv, yog li qhov kub faib hauv cov khoom siv zoo ib yam thiab qib yas yas yog ib yam , yog li txhawb kev ua kom zoo ib yam yas ntawm cov khoom siv PVC.
3. Cov txheej txheem ua haujlwm muaj lub cev hnyav txaus los ua kom cov viscosity (lossis lub zog) ntawm cov yaj, ua kom lub siab yaj thiab tiv thaiv cov khoom los ntawm kev plam thaum lub sijhawm ua, yog li txhawm rau nce lub zog sib tsoo, zoo heev ua rau cov cua sov sib txhuam ntawm yaj thiab cov hlau saum npoo, thiab txhawb kev sib xyaw kom zoo sib xws thiab qib yas ntawm PVC sib xyaw.
Tam sim no, cov khoom yas tau nrov, cov khoom yas tau tsim tas li thiab siv, thiab muaj qhov xav tau zoo rau cov khoom siv ua yas. Kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis txhawb nqa txoj kev lag luam. ACR cov txheej txheem ua haujlwm feem ntau siv cov khoom siv ua haujlwm, nrog cov cua sov zoo, tiv taus kev laus, txhim kho kev ua haujlwm ntawm cov khoom, txhim kho kev ua tau zoo.
ACR kev pab ua haujlwm tau npaj los ntawm kev sib tsoo polymerization ntawm methyl methacrylate nrog alkyl acrylate elastomer, uas muaj&"; core-shell &"; qauv. Nws" core" yog ib hom kev sib txuas qis qis acrylic roj hmab polymer, thiab nws" plhaub" yog hom methyl methacrylate graft polymer nrog kev sib raug zoo nrog PVC. Kev ua ACR tau siv dav hauv PVC cov khoom lag luam hauv Suav teb. Lub hom phiaj tseem ceeb ntawm kev ua ACR yog txhawm rau txhim kho kev ua haujlwm ntawm PVC. Nws feem ntau yog tsim los ntawm kev sib koom ua ke copolymerization ntawm methyl methacrylate nrog methacrylate thiab acrylate. Txawm li cas los xij, kev hloov cua sov thiab txiav lub zog ntawm PVC cob nws tus kheej tsis muaj zog, ua rau tsis sib luag. ACR hloov kho tuaj yeem txhim kho qhov ci ntsa iab ntawm PVC thiab PVC cov khoom.
Kev ua tau zoo ntawm cov khoom yas muaj ntau yam ua nrog kev ua haujlwm pab. Kev tsim kho thev naus laus zis siab tau pab zoo rau cov khoom yas, uas txhim kho nws cov kev ua tau zoo thiab dhau los ua cov khoom siv dav. Ntawm lawv, cov khoom siv ua yas tau nrov npe, thiab ntau thiab ntau yam ntawm lawv ua rau nws yooj yim dua los txhim kho cov khoom siv.
