Chowongolera thovu cha PVC chili ndi kulemera kwakukulu kwa mamolekyulu ndipo chingathandize kwambiri kusungunuka kwa PVC. Chimatha kuphimba mpweya wotulutsa thovu, kupanga kapangidwe ka uchi wofanana, ndikuletsa mpweya kutuluka. Chowongolera thovu cha PVC ndi "industrial monosodium glutamate", chomwe chimagwiritsidwa ntchito pang'ono koma zotsatira zake sizingayang'aniridwe. Kagwiridwe ka ntchito ndi mtundu wa zinthu za PVC zimagwirizana mwachindunji ndi icho. Pambuyo pake, zidapezeka kuti nthawi zambiri, kuphatikiza anthu amkati mwa makampani, amamvetsetsa pang'ono kapena pang'ono za magulu ndi ntchito ya ACR.
Kawirikawiri, zinthu zothandizira processing za PVC ACR zitha kugawidwa m'magulu atatu:
1. Zothandizira pokonza zinthu pogwiritsa ntchito pulasitiki: Mtundu uwu umagwiritsidwa ntchito kwambiri pazinthu zolimba za PVC, makamaka polimbikitsa pulasitiki, kukonza mphamvu zosungunuka za rheological, kuwonjezera kufalikira kwa zinthu zina zothandizira, ndikukweza mtundu wa zinthu. Umagwiritsidwa ntchito pazinthu zambiri za PVC monga ma profiles, mapaipi, mbale (ma coil), ndi zina zotero.
2. Chowongolera thovu: Chowongolera thovu cha PVC, chifukwa cha kulemera kwake kwakukulu kwa mamolekyu, chingathe kusintha kwambiri mphamvu yosungunuka ya zinthu za PVC, kuphimba bwino mpweya wotulutsa thovu, kupanga kapangidwe kofanana ka uchi, ndikuletsa kutuluka kwa mpweya. Nthawi yomweyo, chowongolera thovu cha PVC chimathandizanso kufalikira kwa zowonjezera zina, kuphatikizapo zinthu zotulutsa thovu, kuti chiwongolere mtundu wa zinthu pamwamba ndikuwonjezera kunyezimira. Ndi choyenera matabwa otulutsa thovu, ndodo zotulutsa thovu, mapaipi otulutsa thovu, ma profiles otulutsa thovu, pulasitiki yamatabwa otulutsa thovu, ndi zina zotero.
3. Chithandizo chothandizira kukhetsa mafuta akunja: Chili ndi mphamvu zofanana ndi zachitsulo monga oxidized polyethylene sera, koma ndi chosiyana ndi PVC chifukwa chimagwirizana bwino. Chingathenso kuwonjezera mphamvu yopangira pulasitiki mpaka pamlingo winawake, kusintha mphamvu yosungunuka ya rheological, ndikusunga kukula kwa malo otulutsira mafuta panthawi yopangira mafuta popanda kusintha mphamvu yopangira kutentha. Chimaletsa mphamvu ya nthunzi yomwe imabwera chifukwa cha mvula ya mafuta muzinthu zowonekera. Choyenera kugwiritsa ntchito formula kapena zida zomwe zimafunikira kwambiri pokonza, makamaka mapepala owonekera, ma profiles a thovu, ma board a thovu, ndi mapulasitiki a matabwa a thovu.
4. Makamaka pankhani ya ukadaulo ndi zinthu, panthawi yokonza zinthu, kusinthasintha kwa kusungunuka kumatha kukonzedwa, zomwe zimathandiza kuti zinthu zotsalazo ziyende bwino pakati pa ma rollers awiri; Pakutulutsa chitoliro, mtundu wowonekera ukhoza kukonzedwa, mawonekedwe a "khungu la shark" amatha kuchotsedwa, ndipo kuchuluka kwa kusungunuka kumatha kuwonjezeredwa; Kutulutsa kowonekera kumatha kuchepetsa kwambiri kuchuluka kwa "maso a nsomba" mu chinthucho; Mwa kuwonjezera kusinthasintha kwa kusungunuka mu jekeseni, kuchuluka kwa jekeseni kumachepetsedwa, mawonekedwe a "mizere yoyera" amachepetsedwa, kunyezimira kwa pamwamba kumawonjezeka, ndipo mphamvu yowotcherera imawonjezeka. Ngati zothandizira zopaka mafuta ziwonjezedwa, mphamvu yochotsera filimu imatha kukwera, kuzungulira kwa jekeseni kumatha kufulumizitsidwa, ndipo zokolola zimatha kuwonjezeredwa kuti zipewe "chisanu" chomwe chimayambitsidwa ndi kutsetsereka kwakunja ndi mvula; Kuumba kophulika kumatha kusintha pulasitiki, kuchepetsa mawonekedwe a fisheye, kusintha kusinthasintha kwa kusungunuka, ndikupanga makulidwe a kuumba kukhala ofanana.
