Thaum nws los txog rau kev tsim kho thiab kev tsim khoom, kev xaiv cov ntaub ntawv zoo yog qhov tseem ceeb heev. Ntawm ntau txoj kev xaiv muaj,cov hlau galvanizedthiab cov kauj hlau ib txwm yog ob qho kev xaiv nrov. Kev nkag siab txog lawv qhov sib txawv thiab qhov zoo tuaj yeem pab koj txiav txim siab zoo rau koj qhov project.
Dab tsi yog galvanized steel kauj:
Cov hlau galvanized yog cov hlau ib txwm uas muaj ib txheej zinc los tiv thaiv kev xeb. Cov txheej txheem no, hu ua galvanizing, suav nrog kev muab hlau rau hauv cov zinc uas yaj lossis txheej nws nrog zinc los ntawm electroplating. Qhov tshwm sim yog cov khoom siv ruaj khov uas tuaj yeem tiv taus cov xwm txheej ib puag ncig hnyav.
Dab tsi yog cov hlau kauj ib txwm muaj:
Cov hlau kauj ib txwm muajtsuas yog hlau tsis muaj txheej tiv thaiv. Txawm hais tias nws muaj zog thiab siv tau ntau yam, nws yooj yim xeb thiab xeb thaum raug dej noo thiab lwm yam ib puag ncig. Qhov no ua rau nws tsis haum rau kev siv sab nraum zoov lossis thaj chaw uas muaj dej noo ntau.
Qhov sib txawv loj
Kev tiv thaiv xeb: Qhov sib txawv tseem ceeb tshaj plaws yog kev tiv thaiv xeb. Cov hlau galvanized muaj kev tiv thaiv xeb zoo heev thiab zoo tagnrho rau kev siv sab nraum zoov, thaum cov hlau ib txwm xav tau kev saib xyuas tsis tu ncua kom tiv thaiv kev puas tsuaj.
Lub Neej: Vim yog kev tiv thaiv ntawm cov txheej zinc, lub neej ua haujlwm ntawm cov hlau galvanized ntev dua li cov hlau ib txwm muaj. Qhov no tuaj yeem ua rau txuag tau nyiaj ntau dhau, vim tias kev hloov pauv yuav tsawg dua.
Tus nqi: Thaum tus nqi pib ntawm cov hlau galvanized yuav siab dua vim yogcov txheej txheem galvanizing, lawv lub zog ruaj khov thiab txo qhov yuav tsum tau saib xyuas ua rau lawv yog qhov kev xaiv pheej yig dua hauv lub sijhawm ntev.
Txawm hais tias cov hlau galvanized thiab cov hlau dog dig muaj lawv cov kev siv, cov hlau galvanized sawv tawm vim lawv txoj kev tiv thaiv corrosion thiab lub neej ua haujlwm. Rau cov haujlwm raug rau cov huab cua, kev nqis peev rau hauv cov hlau galvanized tuaj yeem muab kev thaj yeeb nyab xeeb rau koj thiab kev txuag nyiaj mus sij hawm ntev.
