ACR thiab PVC muaj cov polarity zoo sib xws, muaj kev sib raug zoo thiab kev sib raug zoo, thiab nws cov yam ntxwv ua haujlwm yog:
1. Thaum lub sijhawm ua haujlwm kub, nws tuaj yeem txhawb kev sib dhos thiab sib xws ntawm cov khoom siv PVC, txhim kho kev ruaj khov thermal, tiv thaiv cov khoom siv hauv zos, txo cov txheej txheem molding kub, luv lub sijhawm plasticization, thiab txhim kho kev ua haujlwm ntau lawm.
lub
2. Txhim kho qhov fluidity ntawm PVC cov ntaub ntawv, txhawb kev ua tiav du, nce cov khoom tsim tau, thiab txo qhov hnav ntawm cov tshuab ua haujlwm.
lub
3. Txo qhov tso cov khoom ntxiv rau ntawm qhov chaw ntawm lub tshuab, thiab txhim kho qhov zoo li ntawm cov khoom tiav lossis cov khoom tiav ib nrab xws li kev du.
Cov khoom no feem ntau yog siv rau cov khoom pob tshab PVC xws li PVC zaj duab xis thiab PVC daim ntawv. Nws kuj tseem siv tau rau hauv cov khoom siv ua npuas dej PVC.
25Kg/hnab. Cov khoom yuav tsum tau khaws cia kom huv si thaum lub sijhawm thauj mus los, thauj khoom thiab tshem tawm kom tiv thaiv kev raug tshav ntuj, nag, kub thiab av noo, thiab kom tsis txhob puas rau lub pob khoom. Nws yuav tsum tau khaws cia rau hauv qhov chaw txias, qhuav uas tsis muaj tshav ntuj ncaj qha thiab ntawm qhov kub qis dua 40oC rau ob xyoos. Tom qab ob xyoos, nws tseem siv tau tom qab dhau qhov kev tshuaj xyuas kev ua tau zoo.
