Zovala zamagalimoto zimakhala ndi nsalu yamvula yapulasitiki (PE), nsalu zoyalira mpeni wa PVC ndi chinsalu cha thonje.Pakati pawo, nsalu zamvula zapulasitiki zakhala zikukwezedwa kwambiri m'magalimoto chifukwa cha ubwino wake wa kupepuka, kutsika mtengo, ndi kukongola, ndipo wakhala nsaru yoyamba kwa madalaivala kapena eni magalimoto.Nsalu ya mvula ya pulasitiki imapangidwa ndi polyethylene monga zopangira, ndipo imatsirizidwa kupyolera muzitsulo zinayi zojambula, kuluka, zokutira ndi zomalizidwa.Momwe mungasankhire nsalu yamvula yapulasitiki yomwe imakuyenererani?Nkhaniyi ifotokoza zizindikiro zitatu zofunika za nsalu za mvula zapulasitiki.

1. Zopangira

Ubwino wa zipangizo zopangira mwachindunji umatsimikizira mapangidwe a mvula ya pulasitiki.Polyethylene ndi tinthu tating'onoting'ono tomwe timayengedwa ndikufupikitsidwa mu naphtha.Zatsopano polyethylene particles ndi mandala ndi osakhazikika anthu, sanali poizoni ndi zoipa.Choncho, posankha mvula ya pulasitiki, yesetsani kusankha mvula yowonekera komanso yonyezimira.

2. Chilinganizo chogwira ntchito

Chifukwa polyethylene amatha kuchitapo kanthu ndi kuwala kwa ultraviolet ndi mpweya mumlengalenga.Choncho, kuwonjezera zowonjezera zina zogwira ntchito monga zowonjezera zotsutsana ndi UV ndi antioxidants ku nsalu yamvula yapulasitiki sikuti kumangowonjezera ubwino wapachiyambi wa pulasitiki wamvula, komanso kuchedwetsa ukalamba wake ndikuwonjezera kwambiri moyo wake.Pakuzama kwa kafukufuku ndi chitukuko, njira yolimbana ndi abrasion yapangidwa, makamaka pamavuto amakangano komanso zovuta zokoka mphepo zomwe zimakumana ndi kugwiritsa ntchito nsalu zamvula zamagalimoto.

3. Kulemera ndi kukula

Kulemera kwake ndi makulidwe ake zimayenderana, kukhuthala kwake kumapangitsa kuti phula likhale lolemera kwambiri, komanso kulimba kwake.
