pvc resin for film adag
pvc resin loogu talagalay filim adag,
darajada filimka resin PVC, Xabagta PVC ee filimka, Xabagta PVC ee filimka hufan,
Filimyada PVC-ga adag waa baakado badan oo loo isticmaalo codsiyada baakadaha kala duwan.Alaabtu way fududahay in loo isticmaalo si ka duwan waxyaalaha kale ee caagga ah… astaamaheeda sida caddaynta, qaabaynta heerkulka hoose, daabacaadda sahlan ayaa ka dhigaysa badeecad ku habboon.
Wixii soo saarista iyo isticmaalka filimka hufan ee PVC adag, xabagta waxaa lagu gartaa qaybinta cidhiidhi ah ee resin polymerization degree si loo hubiyo in ay waxqabadka plasticizing aad u fiican iyo sifooyinka farsamo wanaagsan. .
Xabagta Polyvinyl chloride (PVC) waa polymer sare oo ay soo saarto polymerization of ethylene.polymerization hakinta waxaa loo isticmaalaa habka polymerization warshadaha ee caadiga ah.Caadiyan waa dhuuban oo lagu jilcinayo kuleylka.Marka la kululeeyo, badanaa waxay leedahay heerkul kala duwan oo dhalaalid ama jilicsan, waxayna ku jiri kartaa xaalad caag ah oo hoos timaada ficilka xoogagga dibadda.Warshadu waxay ku dari kartaa balaastiig ama qalab kale si ay u buuxiso shuruudaha wax soo saarka iyada oo loo eegayo shuruudaha waxqabadka alaabta caagga ah.
Fasalka S-1300 waxaa inta badan loo isticmaalaa in lagu soo saaro alaab dabacsan oo xoog badan, alaabta la riixo, qallafsanaanta qallafsan ee dabacsanaanta iyo walxaha dahaarka, iwm.
