Dab tsi yog qhov txawv ntawm PE tarpaulin thiab PVC tarpaulin? PVC qhov tseeb yog ib hom vinyl polymer, thiab nws cov khoom yog ib hom ntawm cov khoom siv tsis muaj hliv. Kev ruaj khov, roj nplua nyeem, cov koomhaum pabcuam kev ua haujlwm, xim, tiv thaiv tus neeg sawv cev tiv thaiv thiab lwm yam ntxiv tau ntxiv rau PVC cov ntaub ntawv hauv kev siv tiag. PE, nrog tag nrho lub npe ntawm polyyetylene, yog qhov yooj yim tshaj plaws polymer organic compound. Tam sim no, nws yog qhov feem ntau siv cov khoom siv polymer hauv lub ntiaj teb. Nws yog polymerized los ntawm ethylene. Nws tuaj yeem muab faib ua high-density polyethylene, nruab nrab ntom polyethylene thiab ntom ntom polyethylene raws li qhov sib txawv.
Qhov sib txawv ntawm PE tarpaulin thiab PVC tarpaulin
Cov yam ntxwv ntawm PVC tarpaulin:
Nws yog nonflammability, siab zog, huab cua tsis kam thiab zoo heev geometric stability. PVC muaj muaj zog tiv taus oxidant, reductant thiab muaj zog acid. Txawm li cas los xij, nws tuaj yeem kho tau los ntawm cov tshuaj oxidizing acid, xws li muaj cov sulfuric acid thiab concentrated nitric acid, thiab nws tsis tsim nyog rau kev sib cuag nrog uas muaj ntxhiab hydrocarbon thiab chlorinated hydrocarbon.
Cov yam ntxwv ntawm PE tarpaulin:
PE yog mos thiab xav tau waxy. Piv nrog tus qub yas, nws yog qhov sib dua thiab pob tshab. Thaum nws hlawv, nplaim yog xiav.
