Kev ua tau zoo ntawm cov khoom siv sealing

Kev ua tau zoo ntawm cov ntaub ntawv sealing yog ib qho tseem ceeb los xyuas kom meej sealing zoo.Kev xaiv cov ntaub ntawv sealing feem ntau yog nyob ntawm qhov chaw ua haujlwm ntawm cov khoom sib khi, xws li kub, siab, ua haujlwm nruab nrab thiab kev txav mus los.Cov kev cai yooj yim rau cov ntaub ntawv sealing yog raws li hauv qab no:

1. Nws muaj qee yam khoom siv, xws li lub zog tensile, elongation, thiab lwm yam;

2. Zoo elasticity thiab hardness, me me compression teeb;

3. Kub thiab kub tsis kam, tsis muaj decomposition thiab softening ntawm qhov kub thiab txias, tsis hardening ntawm tsawg kub;

4. Tau tshaj qhov nruab nrab ua haujlwm, tsis muaj o, decomposition, hardening, thiab lwm yam;

5. Cov pa oxygen zoo thiab kev laus ua haujlwm, ruaj khov;

6. Hnav tsis kam, tsis muaj corrosion ntawm hlau;

7. Yooj yim tsim thiab tus nqi qis;
