Dab tsi yog qhov txawv ntawm PE ua npuas ncauj daim kab xev thiab EPDM ua npuas ncauj daim kab xev?

PE ua npuas ncauj daim kab xev thiab EPDM ua npuas ncauj daim kab xev yog ob lub npe nrov nplaum daim kab xev siv nyob rau hauv ntau yam kev lag luam rau ntau yam kev siv. Thaum ob daim kab xev muaj cov yam ntxwv zoo sib xws thiab cov txiaj ntsig, muaj qee qhov sib txawv tseem ceeb ntawm ob.

PE ua npuas ncauj daim kab xev yog ua los ntawm polyethylene, ib hom yas uas paub txog nws cov dej noo zoo heev thiab kav ntev. Nws yog ib qho kev sib txuas lus muaj zog thiab ntau yam kev sib txuas uas muaj kev sib txuas zoo rau ntau qhov chaw, suav nrog iav, hlau, thiab yas. PE npuas daim kab xev kuj yog huab cua-resistant, ua rau nws zoo tagnrho rau siv sab nraum zoov. Nws muaj nyob rau hauv ntau yam thicknesses thiab widths kom haum raws li nyias daim ntawv thov.

Ntawm qhov tod tes, EPDM ua npuas ncauj daim kab xev yog ua los ntawm cov khoom siv roj hmab hluavtaws hu ua ethylene propylene diene monomer. Nws yog cov ntaub nplaum mos thiab hloov tau yooj yim uas muaj cov khoom sib khi zoo heev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau huab cua thiab dej nruj sealing. EPDM ua npuas ncauj daim kab xev kuj tseem tiv taus huab cua, ozone, thiab UV hluav taws xob, kom ntseeg tau tias nws tseem siv tau rau lub sijhawm ntev.

Ib qho sib txawv loj ntawm ob daim kab xev nplaum yog lawv cov compressibility. PE ua npuas ncauj daim kab xev yog compressible ntau dua li EPDM ua npuas ncauj daim kab xev, uas txhais tau hais tias nws tuaj yeem yooj yim ua raws li qhov tsis sib xws thiab muab cov cushioning zoo dua. EPDM ua npuas ncauj daim kab xev, ntawm qhov tod tes, yog tsawg compressible tab sis muaj zoo insulating zog, ua rau nws zoo tagnrho rau siv nyob rau hauv hluav taws xob daim ntaub ntawv.

Lwm qhov sib txawv ntawm ob daim kab xev yog lawv cov nqi. PE ua npuas ncauj daim kab xev feem ntau tsis tshua kim tshaj li EPDM ua npuas ncauj daim kab xev, ua rau nws yog ib qho kev xaiv nrov ntawm cov lag luam thiab kev lag luam uas yuav tsum tau siv cov kev daws teeb meem zoo.

Hauv kev xaus, ob qho tib si PE ua npuas ncauj daim kab xev thiab EPDM ua npuas ncauj daim kab xev muab ntau yam txiaj ntsig thiab qhov zoo uas ua rau lawv zoo tagnrho rau kev siv sib txawv. Thaum PE ua npuas ncauj daim kab xev yog ntau compressible thiab nqi-zoo, EPDM ua npuas ncauj daim kab xev muaj zoo rwb thaiv tsev thiab sealing zog. Yog li ntawd, xaiv cov ntaub nplaum zoo yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom uas yuav tsum tau ua.
