Izinhlanganisela ze-PVC zisekelwe ekuhlanganiseni kwe-PVC polymer RESIN kanye nezithasiselo ezinikeza ukwakheka okudingekayo ukuze kusetshenziswe ekugcineni (Amapayipi noma Amaphrofayili Aqinile noma Amaphrofayili Aguquguqukayo noma AmaSpredishithi).I-compound yakhiwa ngokuxubana ngokuseduze ndawonye izithako, ezibuye ziguqulelwe ku-athikili ethi "gelled" ngaphansi kwethonya lokushisa namandla okugunda.Kuye ngohlobo lwe-PVC nezithasiselo, i-compound ngaphambi kwe-gelation ingaba i-powder egelezayo (eyaziwa ngokuthi ingxube eyomile) noma i-liquid ngendlela yokunamathisela noma isisombululo.
Izinhlanganisela ze-PVC uma zakhiwe, kusetshenziswa ama-plasticizers, zibe izinto eziguquguqukayo, ngokuvamile ezibizwa nge-PVC-P.
Ama-PVC Compounds uma enziwa ngaphandle kwe-plasticizer yezinhlelo zokusebenza eziqinile aqokwa i-PVC-U.
I-PVC Compounding ingafingqwa ngale ndlela elandelayo:
Impushana eqinile ye-PVC ehlanganisiwe eyomile (ebizwa ngokuthi i-Resin), equkethe nezinye izinto ezinjengama-stabilizer, izithasiselo, izigcwalisi, iziqinisi, nezinciphisi zamalangabi, kumele ixutshwe kakhulu emshinini wokuhlanganisa.Ukuxuba okuhlakazekayo nokusabalalisa kubalulekile, futhi konke kuhambisana nemikhawulo yokushisa echazwe kahle.
Ngokusho kokwakhiwa, i-resin ye-PVC, i-plasticizer, i-Filler, i-stabilizer nezinye izinsiza zifakwa ekuxubeni kwe-mixer eshisayo.Ngemuva kwemizuzu engu-6-10, khipha ku-mixer ebandayo (imizuzu engu-6-10) ukuze uhlanganise.Inhlanganisela ye-PVC kufanele isebenzise i-mixer ebandayo ukuvimbela impahla ukuthi ihlangane ngemva kwe-mixer eshisayo.
Ingxubevange emva kokwenziwa kwepulasitiki, ukuxutshwa nokuhlakazwa ngokulinganayo endaweni engaba ngu-155°C-165°C bese kufakwa kwingxube Yokubanda.Inhlanganisela ye-PVC encibilikayo bese ihlanganiswa.Ngemuva kokufakwa kwe-pelletizing, izinga lokushisa lama-granules lingehla libe ngu-35°C-40°C.Khona-ke ngemva kwesisefo esidlidlizayo esipholiswe umoya, izinga lokushisa lezinhlayiyana lehla ngaphansi kwezinga lokushisa ukuze lithunyelwe esiseleni somkhiqizo wokugcina ukuze zipakishwe.
