Isilawuli se-foam se-PVC siyisengezo se-polymer esisetshenziselwa ukuthuthukisa ukusebenza kwemikhiqizo ye-foam ye-PVC. Imisebenzi yaso eyinhloko ukwandisa amandla okuncibilika, ukukhuthaza ukufana kwamaseli e-foam, ukuvimbela ukuwa kwamaseli, kanye nokwenza ngcono ukusebenza kokucubungula. Okulandelayo yisingeniso esiphelele kubalawuli be-foam ye-PVC:
1. Indima yomlawuli we-PVC foaming
Thuthukisa amandla okuncibilika: vimbela amabhamuza ukuthi angaqhumi noma ahlangane ngesikhathi senqubo yokugqwala, futhi wenze isakhiwo seseli sifane kakhulu.
Isakhiwo seseli esizinzile: kunciphisa ukuwa kweseli, kuthuthukisa amandla okusebenza kanye nekhwalithi yobuso bomkhiqizo.
Thuthukisa ukusebenza kokucubungula: Lungiselela izakhiwo ze-rheological ze-PVC melt ukuze ifaneleke kakhulu ezinqubweni ze-extrusion, rolling, noma i-injection molding foam.
Ukulungisa ubuningi be-foam: ukulawula usayizi kanye nokusabalala kwe-foam pores ukuze kufezwe umphumela okhanyayo ofiselekayo womkhiqizo.
2. Ukuhlukaniswa kweziguquli ze-PVC foaming
(1) Kuhlukaniswe ngokwesakhiwo samakhemikhali
Ama-ester e-Acrylic (uhlobo lwe-ACR): avame kakhulu, njenge-methyl methacrylate (MMA) – ama-copolymer e-butyl acrylate (BA), anemiphumela emihle kakhulu yokuqinisa ukuncibilika.
I-Styrene acrylonitrile (uhlobo lwe-SAN): Iyakwazi ukumelana nokushisa okuhle futhi ifanele izinqubo zokukhipha amagwebu okushisa okuphezulu.
I-MBS (i-methyl methacrylate butadiene styrene): Inomsebenzi wokulawula ukuqina kanye nokulawula igwebu.
(2) Kuhlukaniswe ngesimo somzimba
Uhlobo lweloshini: olusetshenziswa ngqo ekufakeni i-resin yokunamathisela i-PVC (njengesikhumba sokwenziwa, iphepha lodonga).
Uhlobo lwempuphu: esetshenziselwa ukufaka i-PVC eqinile (njengamabhodi e-foam afakwe i-laminated, amaphrofayili).
3. Amasimu okusetshenziswa komlawuli we-PVC foaming
| indawo yesicelo | imikhiqizo ejwayelekile | Izidingo zomlawuli |
| Ukuhlobisa izakhiwo | Ibhodi le-foam le-PVC, ibhodi lokugudla, iphrofayili yokhuni oluyimbumbulu | Amandla aphezulu okuncibilika, usayizi wembobo efanayo, kanye nokumelana nesimo sezulu okuhle |
| Ingaphakathi Lezimoto | Iphaneli yezinsimbi, iphaneli yomnyango, uphahla | Iphunga eliphansi, ukumelana nokushisa okuphezulu kanye nokumelana nokuguga |
| izinto zokupakisha | Ukupakishwa kwe-buffer, amathileyi okudla | Ayinabo ubuthi futhi ayihambisani nezindinganiso ze-FDA |
| Izinto zezicathulo kanye nesikhumba esenziwe | I-EVA/PVC foam sole, isikhumba esenziwe ngokwenziwa | Ukuthamba okuhle nokuqina okuphezulu |
4. Izici zokukhetha zomlawuli we-PVC foaming
Izindlela zokukhipha amagwebu (ukukhipha amagwebu mahhala, ukukhipha amagwebu esikhumbeni, ukukhipha amagwebu ngamakhemikhali, ukukhipha amagwebu ngokomzimba)
Ubuchwepheshe bokucubungula (ukukhipha, ukubumba ngomjovo, ukugoqa)
Ifomula ye-PVC (i-PVC eqinile, i-PVC ethambile, uhlelo lokugcwalisa)
Uhlobo lwe-ejenti yokufutha (i-ejenti yokufutha ye-AC OBSH、I-sodium bicarbonate, njll.
