Kev soj ntsuam qhov pom kev niaj hnub: Rau cov khoom siv grooved siv nyob rau saum toj no - cov kav dej hauv av, kev soj ntsuam pom pom tau pom zoo txhua lub hlis twg; rau cov neeg nyob hauv cov kav dej faus, kev tshuaj xyuas txhua xyoo yog qhia.
Cov Cheeb Tsam Tseem Ceeb: Cov khoom tseem ceeb- xws li cov ntsiab lus txuas thiab sealing gaskets - yuav tsum tau kuaj xyuas tshwj xeeb txhua 3 mus rau 6 lub hlis txhawm rau tiv thaiv kev foob tsis ua haujlwm.
Kev hloov kho rau cov xwm txheej tshwj xeeb: Kev saib xyuas lub sijhawm yuav tsum luv luv thiab kev tshuaj xyuas zaus nce ntxiv rau cov khoom siv grooved siv nyob rau hauv ib puag ncig corrosive lossis siab - kev ua haujlwm siab.
Raws li kev ua haujlwm ib txwm muaj, cov khoom siv grooved tuav tau zoo tuaj yeem ua haujlwm tau zoo rau ntau xyoo lawm yam tsis tas yuav tsum tau hloov qhov chaw.
