Qhov sib txawv ntawm PP / PU / PE

PP (polypropylene) yog cov khoom siv polymer nrog cov cua kub zoo, kua qaub thiab alkali tsis kam, corrosion kuj thiab txhua yam muaj zog, nrog rau zoo moldability thiab plasticity. PU (polyurethane) yog ib qho elastomer nrog zoo abrasion tsis kam, roj kuj thiab txhua yam muaj zog, nrog rau zoo ozone thiab UV tsis kam. PE (polyethylene) yog cov khoom siv yas uas muaj kev tiv thaiv zoo corrosion, acid thiab alkali tsis kam thiab txhua yam muaj zog, tab sis kuj muaj moldability zoo thiab plasticity.

Qhov kom zoo dua ntawm PP yog nws cov cua kub zoo thiab kev tiv thaiv corrosion, uas tuaj yeem siv dav hauv tshuaj, kho mob, zaub mov thiab lwm yam lag luam. Qhov kom zoo dua ntawm PU yog nws qhov zoo abrasion tsis kam thiab roj tsis kam, uas tuaj yeem siv dav hauv kev tsim khau, tsheb, rooj tog thiab lwm yam. qhov zoo ntawm PE yog nws qhov zoo corrosion kuj thiab molding, uas tuaj yeem siv dav hauv kev ntim khoom, kev tsim kho, kev ua liaj ua teb thiab lwm yam lag luam.

Qhov tsis zoo ntawm PP yog nws qhov tsis zoo ntawm qhov kub thiab txias tsis zoo thiab cuam tshuam tsis kam, thaum muaj kev cuam tshuam rau ultraviolet lub teeb thiab oxidation. Qhov tsis zoo ntawm PU yog nws tus nqi siab thiab yellowing nyob rau hauv lub sij hawm ntev UV raug. Qhov tsis zoo ntawm PE yog nws lub zog tsis muaj zog thiab tsis muaj zog, thaum muaj kev cuam tshuam rau ultraviolet lub teeb thiab oxidation.
