Cov khoom siv raw khoom siv yog cov khoom siv feem ntau siv rau kev teeb tsa cov kav dej, uas feem ntau txhim kho qhov airtightness ntawm cov kav dej sib txuas. Lub npe tshuaj ntawm cov khoom siv raw yog polytetrafluoroethylene. Tam sim no, cov siv lead ua dawb dawb polytetrafluoroethylene siv hauv HVAC thiab cov khoom siv dej thiab tso dej. Kuj tseem muaj cov hlua tshwj xeeb polytetrafluoroethylene rau cov raj xa hluav taws xob. Qhov tseeb, cov ntaub ntawv tseem ceeb yog polytetrafluoroethylene, tab sis qee cov txheej txheem sib txawv. Nws yog cov khoom siv sealing tshiab thiab zoo tagnrho.
Kev siv cov khoom siv raw:
1. Tshem tawm cov roj stain ntawm cov yeeb nkab xov thiab ziab nws.
2. Siv cov kua nplaum txaus rau ntawm cov yeeb nkab xov, ces sib sau ua ke thiab sawv ntsug.
3. Tighten thiab kho lub kaum sab xis hauv 3 feeb tom qab kev teeb tsa, thiab tsis txhob kho nws tom qab kho.
4. Nws yog siv rau steel, tooj liab thiab hlau kav. ambient kub yog siab tshaj 25 degree, thiab lub siab tuaj yeem kuaj 24 teev tom qab kev teeb tsa; Lub sijhawm thov rau stainless hlau, aluminium thiab alloy steel yuav tsum tau muab faib ua ob npaug.
