Cov kav hlau dubthiabcov kav dej galvanizedyog ob lub yeeb nkab uas siv ntau tshaj plaws los thauj cov kua thiab cov pa roj. Yog li, qhov txawv ntawm yeeb nkab dub thiab yeeb nkab galvanized yog dab tsi.
Kev Tiv Thaiv Kev Xeb
Qhov sib txawv tseem ceeb ntawm cov kav hlau dub thiab cov kav hlau galvanized yog kev tiv thaiv corrosion.
Cov yeeb nkab hlau dub yog tsim los ntawm kev siv cov hlau tsis muaj zog. Nws muaj cov pa roj carbon tsawg. Qhov kev tiv thaiv xeb ntawm cov hlau tsis muaj zog tuaj yeem ua kom muaj zog ntxiv los ntawm kev ntxiv cov pa roj carbon.
Ntawm qhov tod tes, cov kav dej galvanized yog npog nrog ib txheej tiv thaiv ntawm zinc. Cov txheej txheem ntawm kev ntxiv ib txheej ntawm zinc hu ua galvanization, uas ua rau cov kav dej muaj cov khoom zoo tagnrho ntawm kev tiv taus corrosion siab dua.
Cov Txheej Txheem Tsim Khoom
Lwm qhov sib txawv tseem ceeb ntawm cov kav hlau dub thiab cov kav hlau galvanized yog cuam tshuam nrog lawv cov txheej txheem tsim khoom. Cov kav hlau dub yog tsim los ntawm kev ncab cov hlau tawm mus rau hauv lub raj tsis muaj qhov sib txuas lossis yuam cov npoo ua ke thiab kaw lawv nrog kev sib txuas.
Cov kav dej galvanized kub-dip yog tsim los ntawm cov kav hlau dub thiab nrog zinc txheej. Cov txheej txheem suav nrog kev ntxuav cov kav hlau acid kom tshem tawm cov xeb lossis oxidation, ntxuav nws nrog cov tshuaj ammonium chloride, zinc chloride, lossis kev sib xyaw ua ke ua ntej muab tso rau hauv lub dab dej galvanizing kub-dip.
Qhov tsos
Cov kav hlau dub tsaus dua li cov kav hlau galvanized. Cov hlau oxide uas tsim thaum lub sijhawm tsim khoom yog qhov ua rau nws zoo li grey. Cov kav hlau galvanized zoo li xim nyiaj-dawb vim yog galvanization. Cov txheej zinc ua rau muaj qhov tiav du thiab zoo dua.
Cov ntawv thov
Ob hom yeeb nkab no muaj cov yam ntxwv sib txawv uas zoo tagnrho rau qee yam kev siv. Qhov zoo sib xws ntawm cov yeeb nkab hlau dub ua rau nws yog qhov kev xaiv zoo tshaj plaws thiab muaj kev nyab xeeb rau kev thauj cov roj av thiab cov roj propane. Cov yeeb nkab hlau dub welded tsis yog tsuas yog pheej yig dua xwb, tab sis kuj yog qhov kev xaiv zoo rau kev xa cov roj av thiab kuj siv rau cov tshuab tua hluav taws.
Cov kav dej hlau dub paub tias yooj yim xeb los ntawm dej. Qhov no yog vim li cas feem ntau siv cov kav dej galvanized los nqa dej. Vim nws muaj peev xwm tiv taus xeb, nws kuj tseem siv tau rau ntau yam kev siv sab nraum zoov thiab kev lag luam. Nws cov kev siv tuaj yeem suav nrog kev ntaiv sab nraum zoov, cov ncej scaffolding, laj kab, cov kav dej phwj tuaj, cov paib kev, thiab kev ywg dej ua liaj ua teb.
Kev ruaj khov
Txawm hais tias nws yog qhov tseeb tias hlau twb yog cov khoom siv ruaj khov, cov kav dej galvanized muaj zog dua vim yog cov txheej zinc tiv thaiv.
Cov txheej zinc ua rau cov kav dej galvanized muaj sia nyob ntev txog li 40 lossis 50 xyoo.
Ntawm qhov tod tes, cov kav dej hlau dub tsis tau pleev xim thiab yog li ntawd tsis ruaj khov. Tsis tas li ntawd xwb, dej kuj yooj yim ua rau cov kav dej hom no xeb.
Tus nqi
Cov kav hlau dub pheej yig dua li cov kav hlau galvanized. Qhov no yog vim tsis muaj txheej zinc. Hloov chaw, cov kav hlau dub raug npog nrog hlau oxide thaum lub sijhawm tsim khoom. Xav txog kev xaiv cov kav hlau dub dua li cov kav hlau galvanized yog tias koj muaj peev nyiaj hauv siab thiab yog tias qhov ruaj khov tsis yog koj qhov kev xav tseem ceeb.
Qhov kev txiav txim siab zaum kawg yuav tsum nyob ntawm seb qhov project xav tau dab tsi.
