Ukwazi kangakanani ngabalawuli be-PVC foaming

1, Indlela ye-Foam:

Inhloso yokwengeza ama-polymer anesisindo sama-molecule aphezulu kakhulu emikhiqizweni ye-foam ye-PVC ukukhuthaza ukwenziwa kwe-PVC ibe yipulasitiki; Okwesibili ukuthuthukisa amandla okuncibilika kwezinto ze-foam ze-PVC, ukuvimbela ukuhlangana kwama-bubbles, nokuthola imikhiqizo ene-foam efanayo; Okwesithathu ukuqinisekisa ukuthi i-melt inoketshezi oluhle, ukuze kutholakale imikhiqizo ebukeka kahle. Ngenxa yokwehluka kwemikhiqizo, imishini, izinqubo, izinto zokusetshenziswa, kanye nezinhlelo zokugcoba ezisetshenziswa abakhiqizi bemikhiqizo ye-foam abahlukene, sithuthukise abalawuli be-foam abanokusebenza okuhlukile ukuze kuhlangatshezwane nezidingo ezahlukene zabasebenzisi.

1. Incazelo Yezinto Ezinegwebu

Ipulasitiki enegwebu, eyaziwa nangokuthi ipulasitiki enegwebu, iyinto ehlanganisiwe enepulasitiki njengesakhi esiyisisekelo kanye nenani elikhulu lamagwebu, okungashiwo ukuthi agcwele igesi.

2. Ukuhlukaniswa Kwezinto Zeshidi Le-Foam

Ngokwezilinganiso ezahlukene zokugqwala, ingahlukaniswa ibe yi-foam ephezulu kanye ne-foam ephansi, futhi ngokuya ngobulukhuni bomzimba we-foam, ingahlukaniswa ibe yi-foam eqinile, eqinile kanye nethambile. Ngokwesakhiwo seseli, ingahlukaniswa ibe yi-foam yamaseli avaliwe kanye ne-foam yamaseli avulekile. Ishidi le-foam le-PVC elisetshenziswa kakhulu lingelashidi le-foam eliphansi elivaliwe.

3. Ukusetshenziswa kwamashidi e-foam e-PVC

Amashidi e-foam e-PVC anezinzuzo ezifana nokumelana nokugqwala kwamakhemikhali, ukumelana nesimo sezulu, kanye nokuphelelwa ilangabi, futhi asetshenziswa kabanzi ezicini ezahlukahlukene, kufaka phakathi amaphaneli okubonisa, izimpawu, amabhodi okukhangisa, izingxenye, amabhodi okwakha, amabhodi efenisha, njll.

4. Izici ezibalulekile zokuhlola ikhwalithi yamashidi e-foam

Kwizinto zokufaka igwebu, ubukhulu kanye nokufana kwe-foam pores kuyizinto ezibalulekile ezithinta ikhwalithi yeshidi. Kumashidi e-foam okukhulisa kancane, ama-foam pores mancane futhi ayalingana, ishidi le-foam linokuqina okuhle, amandla aphezulu, kanye nekhwalithi enhle yobuso. Ngokombono wokunciphisa ubuningi bamashidi e-foam, ama-foam pores amancane nafanayo kuphela anethuba lokunciphisa ubuningi, kuyilapho igwebu elikhulu nelihlakazekile kunzima ukunciphisa ubuningi.
