ACR iyo PVC waxay leeyihiin midab isku mid ah, xiriir la taaban karo iyo waafaqid wanaagsan, iyo sifooyinkeeda shaqo waa:
1. At heerkulka processing, waxa ay kor u qaadi kara synchronous iyo lebbiska plasticization ee alaabta PVC, hagaajinaysaa xasiloonida kulaylka, si wax ku ool ah looga hortago coking maxaliga ah ee alaabta, yaraynaysaa heerkulka samaynta, gaabin waqti plasticization, iyo hagaajinta wax soo saarka.
ah
2. Hagaajinta dareeraha alaabta PVC, kor u habaynta siman, kordhinta dhalidda alaabta, iyo in la yareeyo xidhashada farsamada ee mishiinada processing.
ah
3.Si weyn u yareeya kaydinta waxyaallaha kala duwan ee dusha sare ee mashiinka, oo si weyn u wanaajiya muuqaalka alaabta la dhammeeyey ama alaabta la dhammeeyey sida siman.
Alaabtan waxaa inta badan loo isticmaalaa alaabada hufan ee PVC sida filimada PVC iyo xaashida PVC.Waxa kale oo loo isticmaali karaa alaabada wakiilka xumboynta ee PVC.
25Kg/bac.Alaabta waa in la nadiifiyaa inta lagu jiro gaadiidka, rarista iyo dejinta si looga hortago soo-gaadhista qorraxda, roobka, heerkulka sare iyo qoyaanka, iyo si looga fogaado waxyeello soo gaadha xirmada.Waa in lagu kaydiyaa bakhaar qabow oo qalalan iyada oo aan qorraxdu toos ahayn iyo heerkul ka hooseeya 40oC muddo laba sano ah.Laba sano ka dib, wali waa la isticmaali karaa ka dib marka laga gudbo kormeerka waxqabadka.
