Sealing cov ntaub ntawv yuav tsum ua tau raws li qhov yuav tsum tau ntawm lawv cov sealing muaj nuj nqi. Vim muaj qhov sib txawv ntawm cov xov xwm kaw thiab kev ua haujlwm ntawm cov khoom siv, qhov sib txawv adaptability yuav tsum tau rau cov ntaub ntawv sealing. Cov kev cai dav dav rau cov ntaub ntawv sealing yog:
1) Good material density, preventing leakage of the media.
2) Tsim nyog mechanical zog thiab hardness.
3) Zoo compressibility thiab resilience, nrog tsawg kawg deformation.
4) Tsis muaj softening lossis decomposition ntawm qhov kub thiab txias, thiab tsis muaj hardening los yog tawg ntawm qhov kub thiab txias.
5) Zoo corrosion kuj, muaj peev xwm ua tau ntev - lub sij hawm ua hauj lwm nyob rau hauv xov xwm xws li acids, alkalis, thiab roj, nrog tsawg heev hloov nyob rau hauv ntim thiab hardness, thiab tsis adhesion rau hlau nto.
6) Tsawg coefficient ntawm kev sib txhuam thiab zoo hnav tsis kam.
7) Yooj yim rau kev sib txuas nrog lub sealing nto.
8) Zoo aging kuj thiab durability.
9) Kev ua haujlwm yooj yim thiab tsim khoom, tus nqi qis, thiab cov khoom siv tau yooj yim.
