Cov thoob khib nyiab sab nraum zoov tsis tu ncua raug cuam tshuam rau ib puag ncig hnyav, suav nrog nag, av noo, UV rays, thiab kub hloov pauv. Txhawm rau kom ntseeg tau tias lawv cov kav ntev thiab lub neej ntev, cov chaw tsim khoom siv ntau yam kev tiv thaiv corrosion thiab kev tiv thaiv xeb. Kab lus no qhia txog cov kev siv ntau tshaj plaws los tiv thaiv cov thoob khib nyiab ntawm cov khoom.
Galvanization
Galvanization yog cov txheej txheem siv dav hauv cov hlau saum npoo yog coated nrog ib txheej ntawm zinc. Cov zinc txheej no ua haujlwm los tiv thaiv cov dej noo thiab oxygen kom tsis txhob ncav cuag cov hlau hauv qab, yog li txo qhov kev pheej hmoo ntawm xeb thiab xeb. Galvanized cov thoob khib nyiab yog qhov zoo tagnrho rau kev siv sab nraum zoov vim lawv tsis kam tiv thaiv huab cua thiab lawv lub peev xwm los tswj cov txheej txheem kev ncaj ncees nyob rau lub sijhawm.
Hmoov Txheej
Hmoov txheej yog lwm txoj kev nrov uas suav nrog kev siv cov hmoov qhuav rau saum npoo ntawm cov thoob khib nyiab, uas yog tom qab ntawd ua kom sov los ua cov txheej txheem tiv thaiv. Cov txheej no tsis tsuas yog ntxiv cov xim thiab ua kom tiav, tab sis kuj muab kev tiv thaiv zoo heev rau chipping, khawb, thiab corrosion. Powder-coated cov thoob khib nyiab yog cov khoom siv ruaj khov thiab zoo haum rau cov chaw tsheb loj.
Stainless hlau thiab Anti-Corrosive xim
Stainless hlau yog ib txwm tiv taus xeb vim nws cov ntsiab lus chromium, uas tsim cov txheej txheem oxide tiv thaiv. Thaum cov hlau tsis muaj steel siv rau hauv cov thoob khib nyiab sab nraum zoov, nws muaj kev tiv thaiv ntev ntev yam tsis tas yuav muaj txheej txheej ntxiv. Tsis tas li ntawd, cov tshuaj tiv thaiv corrosive qee zaum siv rau cov hlau nto kom ntxiv dag zog rau lawv cov kev tiv thaiv xeb thiab kev puas tsuaj ib puag ncig.
Kev siv cov txheej txheem xws li galvanization, hmoov txheej, thiab stainless hlau kev tsim kho kom ntseeg tau tias cov thoob khib nyiab sab nraum zoov nyob ruaj khov thiab tiv taus corrosion. Cov txheej txheem no cuam tshuam rau lub neej ntev ntawm cov ntim khoom, ua rau lawv muaj txiaj ntsig zoo rau kev tswj xyuas qhov chaw huv thiab huv si.
