Dab tsi yog qhov tseem ceeb txiav txim siab rau corrosion tsis kam ntawm galvanized square hlab?
Cov ntsiab lus tseem ceeb yog zinc txheej thickness (tuab ntau dua los yog sib npaug ntawm kev tiv thaiv kev ua haujlwm (kev tiv thaiv kev ua haujlwm
Yuav ua li cas tuaj yeem zinc txheej nplaum ntawm galvanized square Hmab leeg raug sim?
Cov feem ntau siv "hla - Txiav kev sim" cuam tshuam nrog zinc txheej saum toj nrog lub zinc txheej saum toj nrog cov hniav (1mm sib txawv), thov kom tshem tawm sai sai. Yog hais tias lub zinc txheej tsis tshem tawm, tsob ntoo adhesion tau siv tau. Lwm txoj kev, tus "khoov tau" yog siv: khoov cov raj Square Raum 180 Degree. Yog hais tias zinc txheej tsis tawg lossis detach, lub raj kis.
Cov Qauv rau lub compressive thiab tensile lub zog ntawm galvanized square Hmab leeg?
Nyob ntawm cov khoom siv hauv paus (piv txwv li, Q235b hlau): tensile lub zog yog kwv yees li 375-500 mpa, tawm los ntawm 235 MPa; Compressive lub zog yog nyob ntawm cov specifications. Piv txwv li, rau 100 × 100 × 100 lub raj 5 hli square, lub axial compressive bearing muaj peev xwm yog kwv yees li ntawm kev ua lag luam engineering).
Dab tsi ua rau "dawb xeb" nyob saum npoo ntawm galvanized square Hmab leeg? Yuav ua li cas thiaj yuav zam tau?
Dawb xeb yog zinc oxide / zinc hydroxide tsim los ntawm oxidation ntawm zinc txheej. Nws yog feem ntau tshwm sim los ntawm cov chaw cia huab cua (av noo> 60%), qhov cua tsis zoo, lossis ntim ntim ua ntej cov txheej zinc ua ntej qhuav. Txhawm rau zam qhov no, muaj kev nyab xeeb qhov cua thiab qhov ziab khaub ncaws thaum lub sijhawm cia, tso ib qho desiccant hauv kev ntim khoom, thiab ua kom dhau los lossis sib khi ua ntej ua zaub mov xa tuaj.
Cov qauv hauv tebchaws twg yuav tsum muaj galvanized square qe sib ntsib? Cov qauv txheej txheem tseem ceeb siv hauv tsev yog GB / t 3091 {{1} {{{3} {} Welded Steel kav thiab lwm cov khoom siv galvanizing thiab lwm cov txheej txheem ntawm cov khoom lag luam steel. " Cov qauv no qhia cov lus qhia tshwj xeeb xws li Zinc Txheej Thickness, adhesion, thiab kev sib txawv.
