Cov qauv zoo rau ua ntej- cov yeeb yaj kiab coated feem ntau tsom rau kev tswj lub cev, tshuaj, thiab cov yam ntxwv ntawm txheej zaj duab xis. Lub cev lub cev muaj xws li zaj duab xis thickness, adhesion, yooj, thiab cuam tshuam tsis kam. Zaj duab xis thickness yuav tsum tsis sib xws thiab ua tau raws li cov qauv tsim. Adhesion raug soj ntsuam siv tus ntoo khaub lig- txiav kev sim lossis rub- tawm kev xeem kom ntseeg tau tias txheej zaj duab xis tsis tev thaum ua thiab siv. Flexibility thiab cuam tshuam tsis kam yog raug sim los ntawm kev khoov, folding, los yog poob lub pob kuaj kom ntseeg tau tias kev ruaj ntseg ntawm txheej thaum thauj, ua, thiab siv.
Cov khoom siv tshuaj lom neeg thiab cov tsos mob zoo kuj yog cov khoom tseem ceeb ntawm cov qauv zoo. Cov khoom siv tshuaj lom neeg feem ntau yog ntsuas kev tiv thaiv corrosion, huab cua tsis kam, thiab tshuaj tiv thaiv, piv txwv li, los ntawm kev ntsuam xyuas cov nyhuv tiv thaiv thiab ua haujlwm ntev ntawm cov txheej txheem los ntawm kev ntsuam xyuas ntsev tsuag, kua qaub thiab alkali immersion tests, los yog ultraviolet aging tests. Cov tsos mob zoo xws li gloss, smoothness, xim sib xws, thiab tsis muaj qhov tsis xws luag xws li npuas, tawg, thiab tev. Los ntawm kev ua raws li cov qauv zoo no, ua ntej- cov yeeb yaj kiab coated tsis tsuas yog ua kom lawv cov kev tiv thaiv kev ua tau zoo thiab kav ntev,
