Ngokusho kwesimo sokwakheka kwe-coextrusion material

Ngokwesimo sokwakheka kwe-coextrusion material, inqubo ye-extrusion yephrofayili yepulasitiki ingahlukaniswa ibe yi-pre coextrusion kanye ne-post coextrusion.I-pre coextrusion ibhekisela ekwakhekeni kwenhlanganisela yezinto ezimbili ngesikhathi sokwakheka okungaphelele;I-post coextrusion isho ukuthi into eyodwa yakheke ngokugcwele bese ihlanganiswa nenye into.Inzuzo ye-post coextrusion ukuthi imfucuza ingasetshenziswa futhi umnotho ungcono.

Ngokusetshenziswa kwe-extrusion

Inqubo ye-extrusion yephrofayili yepulasitiki ingahlukaniswa ibe yi-organic co extrusion kanye ne-inorganic co extrusion ngokusho kwezinto ezihlukene ze-extrusion.I-Organic coextrusion ihlanganisa i-pre coextrusion yento efanayo (njengezinto ezinhle nezinto ezigaywe kabusha), i-pre coextrusion yezinto ezihlukahlukene (ezifana ne-PMMA ne-PVC) kanye ne-post coextrusion ye-PVC ethambile futhi eqinile;I-Inorganic coextrusion ingahlukaniswa ibe i-aluminium-plastic composite coextrusion kanye ne-steel plastic composite coextrusion.

Leli phepha ligxile ku-post coextrusion, i-aluminium yepulasitiki eyinhlanganisela yephrofayili ye-coextrusion, i-coextrusion yephrofayili ehlanganisiwe yepulasitiki yensimbi kanye ne-coextrusion yemibala emibili.

Uma kuqhathaniswa nobuchwepheshe bendabuko be-FCE, ubuchwepheshe be-post coextrusion bunezinzuzo zenqubo elula, isicelo esiguquguqukayo, izinga eliphansi le-scrap, ukubuyisela kalula kanye namandla okunamathela alawulekayo.Njengamanje, ubuchwepheshe busetshenziswa kakhulu ekwenzeni iphrofayili ngomugqa wokuvala iminyango namafasitela.

Ubuchwepheshe bendabuko be-extrusion bephrofayili yepulasitiki yangaphambi kwe-coextrusion iyisinyathelo esisodwa sokwenza ubuchwepheshe.Izinto ezincibilikayo ezinokuziphatha okuhlukile kwe-rheological noma imibala zikhishwa kusuka kuma-extruder angaphezu kwamabili kuya kufa okufanayo okwakhiwa.Lokhu kuncibilika kugeleza kumashaneli ahlukene kudayizi yokwakheka, bese kuhlangana endaweni yokufa ukuze kukhishwe, bese kucolwa emkhonweni wokusetha ukuze kuphole futhi kusethwe.
