Lub siab kub tsis kam ntawm PVC tawv yog nyob ntawm yam xws li nws hom, additives, ua kub thiab siv ib puag ncig. cov
Lub tshav kub kub ntawm cov tawv PVC zoo tib yam yog li 60-80 ℃. Qhov no txhais tau hais tias, nyob rau hauv ib txwm muaj xwm txheej, ib txwm PVC tawv tuaj yeem siv tau ntev ntawm 60 degrees yam tsis muaj teeb meem pom tseeb. Yog tias qhov kub siab tshaj 100 degrees, siv sij hawm luv luv yog qhov siv tau, tab sis yog tias nws nyob hauv qhov kub thiab txias ib puag ncig ntev, kev ua haujlwm ntawm PVC tawv yuav cuam tshuam. cov
Lub tshav kub tsis kam kub ntawm hloov PVC tawv tuaj yeem ncav cuag 100-130 ℃. Hom PVC tawv no feem ntau yog txhim kho los ntawm kev ntxiv cov khoom ntxiv xws li stabilizers, lubricants thiab fillers los txhim kho nws cov cua sov. Cov additives no tuaj yeem tsis tsuas yog tiv thaiv PVC los ntawm decomposing ntawm qhov kub thiab txias, tab sis kuj txo yaj viscosity, txhim kho processability, thiab nce hardness thiab kub tsis kam nyob rau tib lub sij hawm. cov
Qhov kub tsis kam ntawm PVC tawv kuj tseem cuam tshuam los ntawm kev ua haujlwm kub thiab kev siv ib puag ncig. Qhov siab dua qhov ua haujlwm kub, qhov qis dua qhov kub ntawm PVC. Yog tias PVC tawv siv rau lub sijhawm ntev hauv qhov kub thiab txias, nws cov cua sov kuj yuav txo qis. cov
Nyob rau hauv cov ntsiab lus, qhov kub tsis kam ntawm cov tawv PVC zoo tib yam yog nyob nruab nrab ntawm 60-80 ℃, thaum lub siab kub tsis kam ntawm hloov PVC tawv tuaj yeem ncav cuag 100-130 ℃. Thaum siv PVC tawv, koj yuav tsum xyuam xim rau nws qhov kub thiab txias, tsis txhob siv nws nyob rau hauv qhov kub thiab txias ib puag ncig, thiab xyuam xim rau kev tswj qhov kub thiab txias kom ntev nws cov kev pab cuam lub neej. cov
