Transparent frosted PVC pulasitiki chovala ma CD thumba

Chikwama cha PVC zipper kwenikweni ndi mtundu wa thumba la pulasitiki. Chigawo chachikulu ndi polyvinyl chloride, yomwe imakhala yowala mumtundu, yosawononga dzimbiri komanso yolimba. Chifukwa chowonjezera zinthu zina zothandizira monga mapulasitiki ndi anti-aging agents popanga kuti apititse patsogolo kutentha kwake, kulimba, ductility, ndi zina zotero, ndi chimodzi mwa zinthu zodziwika kwambiri, zotchuka komanso zogwiritsidwa ntchito kwambiri padziko lonse lapansi. .

Pali njira zosavuta kusiyanitsa ubwino ndi kuipa kwa PVC zipangizo:

1. Fungo: Kuchuluka kwa fungo lake, m’pamenenso zinthuzo zimaipiraipira. Ena opanga mwadala amawonjezera zonunkhira kuti aphimbe fungo lopweteka, kotero thumba la pulasitiki lokhala ndi fungo lolemera limavulaza thupi, kaya likhale lonunkhira kapena lonunkhira.

Kukhudza kwachiwiri: Kuwala kowoneka bwino kwapamwamba, kumapangitsa kuti zinthu zikhale zoyera komanso zapamwamba kwambiri.

Kung’amba kutatu: Kung’amba kumatanthauza kulimba. Matumba ndi osauka ngati akanang'ambika mu mzere wowongoka ngati pepala. Chikwama chabwino cha pulasitiki choyikapo, ngakhale chosanjikiza chakunja chikung'ambika panthawi yong'ambika, wosanjikiza wamkati akadali wolumikizidwa.

Pali mafakitale ena opanga zovala amagwiritsa ntchito matumba apulasitiki obwezerezedwanso. Zovala zamatumba zapulasitiki zonyamula zovalazi ndi zopanda pake, ndipo ma reagents amankhwala amawonjezeredwa panthawi yopanga, ndikusiya zinthu zina zovulaza m'matumba. Malingana ndi makhalidwe a zipangizozi, muyezo woweruza khalidwe la matumba apulasitiki pazovala ndi chabe "fungo limodzi, maonekedwe awiri, ndi kukoka katatu" .Ngati filimu ya thumba la pulasitiki ili ndi zonyansa padzuwa kapena kuwala, ziyenera kukhala thumba la zobwezerezedwanso.
