Isilawuli se-PVC foaming sinesisindo esikhulu sama-molecule futhi singathuthukisa ngempumelelo amandla okuncibilika kwe-PVC. Singakwazi ukufaka igesi ekhipha igwebu, sakhe isakhiwo sezinyosi esifanayo, futhi sivimbele igesi ukuthi ingaphumi. Isilawuli se-PVC foaming “yi-industrial monosodium glutamate”, esetshenziswa ngamanani amancane kodwa umphumela wayo awunakubukelwa phansi. Ukusebenza kanye nekhwalithi yemikhiqizo ye-PVC kuhlobene ngqo nayo. Kamuva, kwatholakala emsebenzini ukuthi izikhathi eziningi, kufaka phakathi abantu bangaphakathi embonini, banokuqonda okucishe kufane nokuhlukaniswa kanye nomsebenzi we-ACR.
Ngokuvamile, i-ACR yokusiza ekucubunguleni i-PVC ingahlukaniswa ngezigaba ezintathu:
1. Izinsiza zokucubungula uhlobo lwe-plasticization: Lolu hlobo lusetshenziswa kabanzi emikhiqizweni eqinile ye-PVC, ikakhulukazi ukukhuthaza i-plasticization, ukuthuthukisa izakhiwo ze-rheological ezincibilikayo, ukuthuthukisa ukuhlakazeka kwezinye izinsiza, nokuthuthukisa ikhwalithi ebonakalayo yemikhiqizo. Isetshenziselwa imikhiqizo eminingi ye-PVC efana namaphrofayili, amapayipi, amapuleti (ama-coil), njll.
2. Umlawuli we-Foam: Umlawuli we-foam we-PVC, ngenxa yesisindo sawo esikhulu sama-molecule, angathuthukisa kakhulu amandla okuncibilika kwezinto ze-PVC, ahlanganise ngempumelelo igesi ekhipha amagwebu, akhe isakhiwo sezinyosi esifanayo, futhi avimbele ukuphuma kwegesi. Ngesikhathi esifanayo, umlawuli we-foam we-PVC unenzuzo nasekusabalaleni kwezinye izithasiselo, kufaka phakathi ama-ejenti ekhipha amagwebu, ukuthuthukisa ikhwalithi yobuso bemikhiqizo nokuthuthukisa ukukhazimula. Ifanele amabhodi ekhipha amagwebu, izinduku ze-foam, amapayipi e-foam, amaphrofayili e-foam, amapulasitiki ezinkuni ekhipha amagwebu, njll.
3. Usizo lokucubungula uhlobo lokuthambisa lwangaphandle: Lunezakhiwo ezinhle zokusula insimbi ezifana ne-oxidized polyethylene wax, kodwa luhlukile ku-PVC ngoba luhambisana kahle. Lungaphinde lwandise ukusebenza kokucubungula ipulasitiki ngezinga elithile, luthuthukise izakhiwo ze-rheological ezincibilikayo, futhi lugcine ukwanda kokuphuma ngesikhathi sokucubungula ngaphandle kokushintsha ukusebenza kokwakha okushisayo. Luvimbela umphumela womhwamuko obangelwa ukuna kwe-lubricant emikhiqizweni esobala. Lufanele amafomula noma imishini enezidingo eziphezulu zokucubungula, ikakhulukazi amashidi asobala, amaphrofayili e-foam, amabhodi e-foam, kanye namapulasitiki e-foam wood.
4. Ngokukhethekile maqondana nobuchwepheshe nemikhiqizo, ngesikhathi sokucubungula ngokugoqa, ukuqina kokuncibilika kungathuthukiswa, okuvumela ukugoqa okubushelelezi kwezinto ezisele phakathi kwama-roller amabili; Ekukhipheni ipayipi, ikhwalithi ebonakalayo ingathuthukiswa, isimo "sesikhumba sikashaka" singasuswa, futhi izinga lokuphuma lingakhushulwa; Ukukhishwa okusobala kunganciphisa kakhulu inani "lamehlo enhlanzi" emkhiqizweni; Ngokwandisa ukuqina kokuncibilika ekubumbeni komjovo, ivolumu yomjovo iyancishiswa, isimo "semigqa emhlophe" siyancishiswa, ukukhanya kobuso kuyathuthukiswa, futhi amandla okushisela ayathuthukiswa. Uma kufakwa izinsiza zokucubungula ukugcoba, ukusebenza kahle kokususa ifilimu kungathuthukiswa, umjikelezo womjovo ungasheshiswa, futhi isivuno singandiswa ukuvimbela isimo "seqhwa" esibangelwa ukushelela kwangaphandle kanye nemvula; Ukubumba okuvuthayo kungathuthukisa ukwenziwa kwepulasitiki, kunciphise isimo se-fisheye, kuthuthukise ukuqina kokuncibilika, futhi kwenze ukujiya kokubumba kufane kakhudlwana.
