Txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no thiab kev sib koom ua ke ntawm kev sib khi kev qhuab qhia ntawm cov tshuab sealing xav tau cov engineers thiab cov kws tshaj lij kom muaj kev paub ntau dua ntawm cov khoom sib khi. Kev xaiv tsim nyog thiab siv tau zoo ntawm ntau yam khoom sib khi yuav ua rau muaj txiaj ntsig zoo thiab kev lag luam. Kev paub txog cov ntaub ntawv sealing feem ntau muaj cov hauv qab no:
(1) Cov kev cai ntawm niaj hnub engineering rau sealing cov ntaub ntawv, kev faib thiab kev loj hlob qauv ntawm sealing cov ntaub ntawv rau mechanical seals;
(2) Kev xaiv cov ntaub ntawv sib khi (cov ntaub ntawv sib txhuam sib txuas, cov khoom siv sib khi, cov khoom siv roj hmab, cov khoom ntim, cov nplaum, O-rings, cov ntawv roj hmab asbestos);
(3) Kev faib tawm, kev ua tau zoo, kev qhia tshwj xeeb thiab hom ntawm cov khoom siv ceramic sealing;
(4) Kev faib tawm, kev ua tau zoo, kev qhia tshwj xeeb thiab hom graphite sealing cov ntaub ntawv;
(5) Kev faib tawm thiab kev ua haujlwm, kev qhia tshwj xeeb thiab hom roj hmab sealing cov ntaub ntawv;
(6) Kev faib tawm ntawm cov khoom siv polymer sealing, kev faib tawm thiab kev ua haujlwm ntawm cov khoom siv ntxhib engineering rau kev sib khi, cov lus qhia tshwj xeeb thiab cov npe ntawm cov khoom siv siab molecular sealing, kev faib tawm thiab kev ua haujlwm ntawm sealants, specifications thiab hom sealants;
(7) Lwm yam tsis-Jincheng sealing cov ntaub ntawv (tawv, ntaub, cardboard, asbestos);
(8) Kev faib tawm thiab kev ua tau zoo, cov lus qhia tshwj xeeb thiab cov npe ntawm cov khoom siv ferrous thiab non-ferrous hlau sealing;
(9) Cov ntaub ntawv sealing tshiab (cov graphite hloov tau, cov ntaub ntawv sib xyaw).
