Kanema wa Nayiloni Wachikwama Coextrusion Wakusanjikiza Zisanu ndi ziwiri Wogula

Matumba a vacuum vacuum vacuum matumba ang'onoang'ono a vacuum, zikwama zotchingira zotchinga zapakatikati ndi matumba apamwamba otchingira otchinga kuchokera pazotchinga.Pankhani ya magwiridwe antchito, imatha kugawidwa m'matumba a vacuum otsika kutentha, matumba otsekemera osamva kutentha kwambiri, zikwama zotsekera zotsekera, zikwama zocheperako, matumba odzithandizira okha ndi zikwama za zipper.Chifukwa zinthu zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana pakulongedza zinthu, kusankha zinthu kuyenera kupangidwa molingana ndi zomwe zidapangidwa, kuphatikiza: kaya ndizosavuta kuwonongeka, zomwe zimapangitsa kuwonongeka (kuwala, madzi kapena mpweya, ndi zina), mawonekedwe azinthu, kuuma kwa zinthu. , zinthu zosungirako, kutentha kwa sterilization, etc. Chikwama chabwino cha vacuum sichiyenera kukhala ndi ntchito zambiri, koma chimadalira ngati chiri choyenera kwa mankhwalawa.

Pakuti mankhwala ndi mawonekedwe wokhazikika kapena pamwamba zofewa, monga mankhwala soseji, nyemba mankhwala, etc., si koyenera amafuna mkulu mawotchi mphamvu zakuthupi, koma ayenera kuganizira chotchinga katundu wa zinthu ndi zotsatira za yolera yotseketsa kutentha. pa zinthu.Chifukwa chake, pazogulitsa zotere, matumba onyamula a opa/pe nthawi zambiri amagwiritsidwa ntchito.Ngati kutentha kwapamwamba (pamwamba pa 100 ℃) kumafunika, mawonekedwe a opa/cpp angagwiritsidwe ntchito, kapena PE yosagwirizana ndi kutentha ingagwiritsidwe ntchito ngati wosanjikiza wosindikiza kutentha.
