Isikhumba sokwenziwa sePVC luhlobo lwemathiriyeli edibeneyo eyenziwe ngokudibanisa i-polyvinyl chloride okanye ezinye iireyini ezinezongezo ezithile, ukwambathisa okanye ukulalisa kwi-substrate kwaye emva koko zicutshungulwe. Ifana nesikhumba sendalo kwaye ineempawu zokuthamba kunye nokumelana nokugqoka.
Ngexesha lenkqubo yemveliso yesikhumba eyenziweyo yePVC, amasuntswana eplastiki kufuneka anyibilike kwaye axutywe kwisimo esingqindilili, aze agqunywe ngokulinganayo kwisiseko selaphu elinithiweyo le-T / C ngokobunzima obufunekayo, kwaye emva koko ungene kwiziko eligwebu ugwebu ukuqalisa ukugwebu. ukuze ikwazi ukwenza iimveliso ezahlukeneyo kunye neemfuno ezahlukeneyo zokuthamba. Ngelo xesha, iqala unyango olungaphezulu (ukudaya, ukudibanisa, ukupholisa, i-matte, ukugaya kunye nokuphakamisa, njl., Ngokukodwa ngokweemfuno zemveliso zangempela).
Ukongeza kokwahlulwa ngokweendidi ezininzi ngokwe-substrate kunye neempawu zesakhiwo, i-PVC yesikhumba eyenziweyo yahlulwe ngokubanzi ngokwezi ndidi zilandelayo ngokwendlela yokucubungula.
(1) Isikhumba sokwenziwa sePVC ngokukhuhla indlela
① Indlela yokukrala ngokuthe ngqo ye-PVC yesikhumba sokwenziwa
② Indlela yokukrazula engathanga ngqo ye-PVC yesikhumba eyenziweyo, ekwabizwa ngokuba yindlela yokudlulisa i-PVC yesikhumba sokwenziwa (kubandakanywa nendlela yentsimbi yentsimbi kunye nendlela yokukhupha iphepha);
(2) Indlela yekhalenda yePVC eyenziwe ngesikhumba;
(3) Indlela ye-Extrusion ye-PVC eyenziwe ngesikhumba;
(4) Indlela yokugquma isikrini sePVC eyenziwe ngesikhumba.
Ngokosetyenziso oluphambili, lunokwahlulwa lube ziindidi ezininzi ezifana nezihlangu, iingxowa kunye neempahla zesikhumba, kunye nezinto zokuhombisa. Kuhlobo olufanayo lwesikhumba esenziwe ngePVC, sinokwahlulwa ngokweendlela ezahlukeneyo zokuhlela.
Umzekelo, ilaphu lemarike elenziwe ngethwathwa linokwenziwa libe lithwathwa eliqhelekileyo lokukhuhla okanye ufele olunogwebu.
