Ungakwenza ngcono kanjani ukumelana nokubanda kwefilimu elithambile le-PVC

Njengengxenye ebalulekile yefomula yemikhiqizo ethambile ye-PVC, ipulasitiki inethonya elikhulu ekusebenzeni kwemikhiqizo ethambile ye-PVC. Uma imikhiqizo ethambile ye-PVC (PVC ebandayo yokugcina umnyango wesitoreji) iyadingeka ukuthi isetshenziswe emazingeni okushisa aphansi, amapulasitiki anokumelana okuhle kwezinga lokushisa kufanele akhethwe. Njengamanje esetshenziswa njengamapulangwe angenakubanda ama-dibasizers anamafutha amaningi, ama-phthalic acid espers e-linear alcohols, amafutha acid espers e-dihydric adloadlic, kanye namafutha e-epoxy fatty monoes.

Njengoba sonke sazi, noma ngabe yi-PVC Plastic Hoses noma imikhiqizo ethambile ye-PVC efana namakhethini omnyango wePVC, ayoba nzima ebusika. Inani lamapulasitiki likhuphuke ngokufanele, futhi amapulasitiki angenakubanda angabanda angangezwa ngendlela efanele. I-DOA (DIOCYLL ADIPATE), i-Dida (dodecyl adipate), doz (dioctyl azelate), dos (dioctyl sebacate) yimimeleli amapulasitiki amelana nawo abandayo. Kusukela ukuhambisana kwama-Plasticis angenakubalwa okubandayo ane-PVC akukuhle kakhulu, eqinisweni, kungasetshenziswa kuphela njengesesitiki esisizayo ukuthuthukisa ukumelana okubandayo, futhi umthamo wawo uvame ukuba ngu-5 ~ 20% wepulasitiki oyinhloko.

Ucwaningo luveze ukuthi inhlanganisela yepulasitiki engamelana nokubanda ne-hexamethyl phosphoric triamide ingathuthukisa ubunzima obubandayo bokubanda nokugcwala okushisa okuphansi kwefilimu ethambile ye-PVC. Yize i-hexamethyl phosphoric treamide ngokwayo akuyona ipulasitiki engamelana nokubanda, inganciphisa ngempumelelo iphuzu elibandayo lamapulasitiki ahlukahlukene futhi lifinyelele inhloso yokuqinisa imiphumela engazweli ebandayo yefilimu ethambile ye-PVC.

Ngasikhathi sinye, kufanele futhi sicabangele ithonya lokushisa lokushisa, izinga lokushisa lokupholisa, nezinye izinto ekumelaneni okubandayo kwe-PVC, bese lihlangana ne-formula design enhle ukwenza ushintsho oluhambisanayo ngesikhathi lapho amazinga okushisa ehla kakhulu.
