Galvalume hlauib qho alloy plating steel ntawv uas ua ke qhov zoo tshaj plaws ntawm qhov zoo ntawm zinc (tus kheej-saving zog, anti-alkaline) thiab txhuas (durability, kub tsis kam, acid kuj).
Qhov hnyav ntawm txheej plating yog ua los ntawm 55% txhuas (Al), 43.4% zinc (Zn), 1.6% silicon (Si). Lub ntim ntawm cov txheej plating yog tsim los ntawm ntau tshaj 80% ntawm txhuas yog li nws tuaj yeem siv tag nrho cov txiaj ntsig ntawm txhuas, thaum txo qis qhov tsis muaj zog (liab xeb ntawm cov khoom raug) los ntawm cov khoom ntiag tug ntawm zinc.
Zoo heev durability
Muab piv rau galvanized steel daim hlau ntawm tib lub plating thickness, lub durability yog 3 ~ 6 lub sij hawm zoo dua, thiab peb xyuas kom meej tias nws yuav tuav nws tag nrho cov kev ua tau zoo rau 20 xyoo nyob rau hauv standard thaj chaw.
Kev kub hauj lwm zoo heev
Cov ntsiab lus txhuas ntawm cov txheej plated yog 80% (ntim piv) thiab tuaj yeem siv tau rau lub sijhawm ntev txawm tias nyob rau hauv qhov kub thiab txias (315 degree) yam tsis muaj qhov cuam tshuam los yog oxidation.
Kev pleev xim zoo heev
Piv raugalvanized steel ntawv, cov xim adheres zoo rau lub plating txheej.
Zoo heev machinability
Machinability yog yuav luag zoo tib yam nrog galvanized steel los xij. Tshwj xeeb, muaj cov kab nrib pleb tsawg dua nyob rau hauv cov txheej txheem plated thaum lub sij hawm machining, ua rau cov khoom siv tau ntev dua.
