Ama-compound e-PVC asekelwe ekuhlanganisweni kwe-PVC polymer RESIN kanye nezithasiselo ezinikeza ukwakheka okudingekayo ekusetshenzisweni kokugcina (Amapayipi noma Amaphrofayili Aqinile noma Amaphrofayili Aguquguqukayo noma Amashidi). I-compound yakhiwa ngokuxuba izithako ndawonye ngokuseduze, okuthi kamuva iguqulwe ibe yinto "efakwe ijeli" ngaphansi kwethonya lokushisa namandla okusika. Kuye ngohlobo lwe-PVC kanye nezithasiselo, i-compound ngaphambi kokufakwa kwejeli ingaba yimpuphu egeleza ngokukhululeka (eyaziwa ngokuthi ingxube eyomile) noma uketshezi ngesimo se-paste noma isixazululo.
Ama-PVC compounds uma ehlanganiswa, kusetshenziswa ama-plasticizer, abe izinto eziguquguqukayo, ngokuvamile ezibizwa ngokuthi i-PVC-P.
Ama-PVC compounds uma enziwe ngaphandle kwe-plasticizer ukuze asetshenziswe ngokuqinile abizwa ngokuthi i-PVC-U.
Ukuhlanganiswa kwe-PVC kungafingqwa kanje:
Impuphu yengxube eyomile ye-PVC eqinile (ebizwa ngokuthi i-Resin), equkethe nezinye izinto ezifana neziqinisi, izithasiselo, izigcwalisi, iziqinisi, kanye nezithiya zomlilo, kumele ixutshwe kakhulu emshinini wokuhlanganisa. Ukuxubana okuhlakazayo nokusabalalisa kubalulekile, futhi konke kuhambisana nemikhawulo yokushisa echazwe kahle.
Ngokusho kwefomula, i-resin ye-PVC, i-plasticizer, i-Filler, i-stabilizer kanye nezinye izinto ezisizayo zifakwa ekuxubeni kwe-hot mixer. Ngemva kwemizuzu engu-6-10 khipha ku-hot mixer (imizuzu engu-6-10) ukuze uxube kusengaphambili. I-PVC compound kumele isebenzise i-cold mixer ukuvimbela ukuthi izinto zinamathele ndawonye ngemva kwe-hot mixer.
Izinto ezihlanganisiwe ngemva kokufakwa kwepulasitiki, ukuxuba nokuhlakazeka ngokulinganayo cishe ku-155°C-165°C bese kufakwa engxubeni ye-Cold. Ukuhlanganiswa kwe-PVC okuncibilikayo kube sekufakwa i-pellet. Ngemva kokufakwa i-pellet, izinga lokushisa lama-granules lingehliswa liye ku-35°C-40°C. Ngemuva kwesihlungo esidlidlizayo esipholile nomoya, izinga lokushisa lama-particle lehla ngaphansi kwezinga lokushisa legumbi ukuze lithunyelwe esigungwini sokugcina somkhiqizo ukuze lipakishwe.
