Cov qauv tsim ntawm galvanized steel kav yog ua raws li cov ntsiab lus ntawm "matrix reinforcement + deg tiv thaiv." Los ntawm ntau- txheej sib koom ua ke, nws ua tiav qhov sib npaug ntawm lub zog siab thiab corrosion kuj. Nws txoj kev tsim kho tuaj yeem muab faib ua ob qhov tseem ceeb: lub hauv paus steel yeeb nkab thiab txheej txheej tiv thaiv galvanized. Txhua txheej suav nrog cov kev xav txog engineering tshwj xeeb.
Lub hauv paus steel yeeb nkab yog lub hauv paus ntawm cov qauv. Nws feem ntau yog ua los ntawm siab- zoo carbon structural steel los yog qis- alloy steel, txias- dov los yog kub- dov, muaj zog txhua yam thiab kev ua tau zoo. Cov yeeb nkab hla- ntu feem ntau yog ncig, tab sis nws kuj tuaj yeem ua rau hauv square, duab plaub, thiab lwm yam tsis xwm yeem raws li qhov yuav tsum tau ua. Cov phab ntsa tuab yog muab qhab nia raws li qhov ntsuas siab thiab daim ntawv thov scenario, kom ntseeg tau tias nws tuaj yeem tiv taus lub siab sab hauv thiab sab nraud thaum tsis txhob muaj cov khoom siv rov ua dua. Qhov txuas ntxiv ntawm cov khoom siv hauv paus yog qhov tseem ceeb. Welded steel kav yuav tsum xyuas kom meej tias lub zog weld tsis qis dua li ntawm cov khoom siv hauv paus, thaum seamless steel kav tshem tawm cov pob qij txha los ntawm kev tho, cov txheej txheem txias txias / dov, txo qhov kev pheej hmoo ntawm kev tawg thiab tawg los ntawm qhov chaw.
Cov txheej tiv thaiv galvanized yog txheej txheej tseem ceeb ntawm cov qauv, nrog kub -dip galvanizing yog cov txheej txheem tseem ceeb. Zinc txheej tsis yog tsuas yog ib txheej adhesion, tab sis yog ib qho kev sib xyaw ua ke tsim los ntawm cov tshuaj tiv thaiv metallurgical nrog substrate, muaj zinc- hlau alloy txheej (puab txheej) thiab cov zinc txheej ntshiab ( txheej txheej). Lub alloy txheej muaj siab hardness thiab muaj zog adhesion, resisting mechanical puas; cov zinc txheej ntshiab yog softer tab sis muaj zoo ductility, npog microscopic defects nyob rau hauv lub substrate thiab tsim ib tug nruam barrier. Lub uniformity ntawm zinc txheej thickness ncaj qha cuam tshuam rau kev tiv thaiv zoo. Cov qauv qhia tias qhov nruab nrab tuab ntawm zinc txheej rau cov qib zoo tib yam yuav tsum tsis txhob tsawg dua 65μm, thaum rau cov qib tuab nws tuaj yeem ncav cuag 85μm, ua kom ntev -lub sij hawm ruaj khov nyob rau hauv ib puag ncig nyuaj xws li cua thiab av.
Qhov no "rigid{0}} yoog raws" tus qauv tsim muab galvanized steel kav ob lub load- bearing toughness ntawm lub substrate thiab lub active corrosion tiv thaiv muaj peev xwm ntawm zinc txheej, ua rau nws ib tug classic piv txwv ntawm cov yeeb nkab qauv uas sib npaug kev nyab xeeb thiab kev lag luam.
