Weatherability: Tus yuam sij rau cov yeeb yaj kiab tiv thaiv ntev

Nyob rau hauv ntau yam kev ua tau zoo ntawm cov yeeb yaj kiab tiv thaiv (viscosity, thickness, xim, elasticity, transmittance, thiab lwm yam.) Ib qho ntawm lawv yog huab cua muaj peev xwm, uas txhais tau hais tias huab cua huab cua yog nyob rau ntawm ib puag ncig huab cua tsis kam; vim li cas ho yog ib zaj yeeb yaj kiab tiv thaiv los qhia txog tus yam ntxwv no? Lub wearability ntawm zaj duab xis ua rau muaj kev cuam tshuam zoo ntawm cov yeeb yaj kiab tiv thaiv.

　　Tiv thaiv zaj duab xis nyob rau hauv kev siv cov txheej txheem ntawm kev tiv thaiv ntawm cov khoom tiav lawm kuj yuav tsum tau ncaj qha mus rau lub hnub, uas yuav tsum tau rau 6 lub hlis mus rau 1 xyoo los yog li ntawd nyob rau hauv cov txheej txheem feem ntau tsis tshwm sim nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj rau lub tiv thaiv zaj duab xis, tab sis yuav muaj kev hloov pauv hauv kev ua haujlwm. Nws kuj tseem yuav tsum tau muab dai rau hauv ib lub thawv hla dej hiav txwv rau ob peb lub hlis. Ib puag ncig uas tiv thaiv zaj duab xis ntsej muag yog qhov hnyav heev.

Cov yeeb yaj kiab tiv thaiv muaj kev ua haujlwm zoo heev thiab muaj ntau yam raws li tus neeg siv cov kev xav tau ntawm tensile hardness, modulus ntawm elasticity, elongation, thiab lwm yam. nyob rau hauv cov txheej txheem ntawm kev hloov khoom siv thiab kev ua, cov yeeb yaj kiab tiv thaiv yuav tsis buckle lossis poob.

Cov zaj duab xis tiv thaiv tau zoo heev huab cua tsis kam thiab adhesion stability; ntau tshaj li ob peb hnub los yog lub sij hawm ntev los lo nrog lub zog tev tawm yuav tsis muaj qhov nce ntxiv, yooj yim rau poob, thiab tsis pom thaum qhov kev tiv thaiv zoo li yuav tsis tawm qhov seem seem, yuav tsis tawm hauv qhov ntxoov ntxoo. ( Ntawm qhov tod tes, nws kuj yog ib hom kev tiv thaiv)

Cov yeeb yaj kiab tiv thaiv tau siv rau qee lub sijhawm tom qab nws qhov chaw protruded, tab sis ob sab ntawm lub qaij yog warping. Qhov laj thawj loj tshaj plaws rau qhov tshwm sim no yog tias cov yeeb yaj kiab tiv thaiv ntawm cov profiles siv hauv kev tshaj tawm cov kev sib tw siab thiab tom qab ntawd ntsib nyob rau hauv qhov kub thiab txias ib puag ncig yuav yog qhov tsis tsim nyog shrinkage tshwm sim.

Cov yeeb yaj kiab tiv thaiv ntawm qhov teeb meem no tshwm sim ntau dua thaum lub caij kub thiab los nag, yog li cov yeeb yaj kiab tiv thaiv hauv cov txheej txheem tsim khoom yuav tsum tau them sai sai rau qhov kub ntawm qhov sib txawv ntawm qhov cuam tshuam ntawm kev siv cov khoom. Txhawm rau kom tsis txhob muaj cov txheej txheem ua yeeb yaj kiab, muaj qhov tsis tsim nyog ntawm kev ncab.
