- 1.PVC resin powder
Yimpahla eyisisekelo esetshenziswayo, isisekelo esinamagwebu, ekhiqiza ishidi elinegwebu le-PVC ngokuvamile lamukela i-Model SG-8 PVC resin.Lapho ucutshungulwa, isivinini se-gelatinization siyashesha, izinga lokushisa lokucubungula liphansi, izinga lomkhiqizo lizinzile, futhi ukuminyana kulula ukulawula.Ukuze uthuthukise ikhwalithi yomkhiqizo futhi ulawule ngokuqinile ukuguquguquka kokuminyana nokuqina komkhiqizo, i-SG-8 PVC resin ivame ukusetshenziswa ekukhiqizeni amashidi amahhala wegwebu kanye ne-Celuka Foam PVC.
- I-2.PVC stabilizer
Ukuze ugcwalise ngokugcwele izinto ezibonakalayo ngesikhathi senqubo yebhodi legwebu le-PVC, impahla ngokuvamile isezingeni eliphezulu lokushisa.Ngaphezu kwalokho, i-ejenti enegwebu iphinde ikhiqize ukushisa okubola ngesikhathi sokubola.Lezi zici zidinga ukuthi i-stabilizer ibe nokuzinza okwanele kokushisa ukuze kuqinisekiswe ikhwalithi yemikhiqizo kanye nokukhiqizwa okuzinzile kwesikhathi eside. - 3.Igwebu isilawuli
Yenziwe nge-methyl methacrylate, i-ethyl acrylate, i-butyl acrylate, ne-styrene.Isakhiwo sayo samangqamuzana siwumgogodla wegobolondo.Njengensiza yokucubungula ohlelweni lokubunjwa, inganciphisa ngempumelelo izinga lokushisa le-plasticizing, ikhuthaze umphumela we-plasticizing, ithuthukise ukusebenza kahle kwe-plasticizing, ithuthukise amandla okuncibilika, inciphise ukuncibilika kwe-ncibilika, ivimbele ukuphuka kwe-ncibilika, futhi ithuthukise ngokuphawulekayo ukushelela kwemikhiqizo. .Umgomo wokukhetha wesilawuli esinamagwebu uhlanganisa isivinini se-plasticizing, amandla okuncibilika, kanye nokuncibilika kwamanzi.Ngenxa yezimo ezihlukene zenqubo, amamodeli okulawula amagwebu kufanele akhethwe ngokuvumelana nezici ezihlukahlukene zempahla yomkhiqizo, njengeshidi elinegwebu, ishidi elinogwebu eliwugqinsi, ishidi elinogwebu elincanyana, ishidi lokhuni elinegwebu lepulasitiki, njll. Bangaqinisekisa ukufana kokuncibilika nokuhle. izinga eliphezulu lebhodi.Ngaphandle kwalokho, sidinga ukukhetha izinto zokugcoba ezingaphakathi nezangaphandle zekhwalithi enhle futhi sengeze iziqinisi ezanele zokushisa efomini. - 4.I-ejenti ekhipha amagwebu
I-ejenti ekhipha amagwebu into eyenza into ibe yisakhiwo seseli.Ingahlukaniswa ngekhemikhali ekhihliza amagwebu, i-ejenti eyenza amagwebu ngokomzimba, kanye ne-surfactant.Isetshenziselwa kakhulu ukulawula ukuminyana kanye nesilinganiso samabhodi e-PVC anegwebu. - 5.Ukugcwalisa
Kuhlelo lwefomula, umthamo ojwayelekile we-calcium carbonate ekhanyayo ngu-10 ~ 40 phr.Isigcwalisi asikwazi ukusetshenziswa nje kuphela njenge-ejenti enegwebu lenucleating kodwa futhi sinciphisa izindleko zezinto ezibonakalayo.Kodwa-ke, umthamo oweqile we-calcium carbonate ekhanyayo uzokwenza ukufana kweseli kube kubi kakhulu, bese kuthinta ukubukeka nekhwalithi yomkhiqizo.Ekugcineni kwenza ukuminyana komkhiqizo kube nzima ukulawula, kwandisa izindleko eziphelele, futhi kunciphisa ubulukhuni bomkhiqizo. - 6.I-Pigment
Isetshenziselwa ukufaka imibala ebhodini, ikakhulukazi emhlophe, ebomvu, ephuzi, eluhlaza okwesibhakabhaka, eluhlaza, emnyama, empunga, njll.
