Kev ua tau zoo ntawm cov khoom siv tshuab yog qhov tseem ceeb hauv kev ua kom muaj txiaj ntsig zoo ntawm cov tshuab

1. Mechanical foob cov ntaub ntawvyuav tsum muaj qee yam khoom siv xws li lub zog tensile, elongation, thiab lwm yam;

2. Elastic thiab hardness, compression mus tas li deformation;

3. Qhov kub thiab txias tsis kam, tsis muaj decomposition, softened, tsis kub nyob rau hauv high kub;

4. Hloov mus rau qhov nruab nrab ua haujlwm, tsis txhob ua o, yooj yim rau decompose thiab harden cov khoom siv foob;

5. Cov pa oxygen tsis kam thiab kev laus ua haujlwm, ua haujlwm ntev;

6. Hnav tsis kam, tsis muaj corrosion hlau;

7. Mechanical seal cov ntaub ntawv yuav tsum tau yooj yim tsim, thiab tus nqi qis;
