Chikopa chochita kupanga cha PVC ndi mtundu wazinthu zophatikizika zomwe zimapangidwa pophatikiza polyvinyl chloride kapena utomoni wina wokhala ndi zowonjezera zina, kuzikuta kapena kuziyika pa gawo lapansi ndikuzikonza. Zimafanana ndi zikopa zachilengedwe ndipo zimakhala ndi makhalidwe ofewa komanso kuvala kukana.
Pa kupanga PVC chikopa yokumba, particles pulasitiki ayenera kusungunuka ndi kusakaniza mu dziko wandiweyani, ndiyeno wogawana TACHIMATA pa T / C oluka nsalu m'munsi malinga ndi makulidwe chofunika, ndiyeno kulowa thobvu ng'anjo kuyamba thovu, kotero kuti amatha kukonza zinthu zosiyanasiyana ndi zofunika zosiyanasiyana zofewa. Panthawi imodzimodziyo, imayamba chithandizo chapamwamba (kudaya, kujambula, kupukuta, matte, kugaya ndi kukweza, etc., makamaka malinga ndi zofunikira zenizeni).
