Kub Dip Galvanized Yeeb Nkab
Cov yeeb nkab galvanized kub-dip reacts cov hlau molten nrog cov hlau substrate los tsim ib txheej alloy, yog li ntawd cov substrate thiab txheej tau sib xyaw ua ke. Kub-dip galvanizing yog pickle cov yeeb nkab hlau ua ntej. Yuav kom tshem tawm cov hlau oxide ntawm qhov chaw ntawm cov yeeb nkab hlau, tom qab pickling, nws raug ntxuav los ntawm ammonium chloride lossis zinc chloride aqueous kua lossis cov kua aqueous sib xyaw ntawm ammonium chloride thiab zinc chloride, thiab tom qab ntawd xa mus rau lub tank txheej kub-dip. Kub-dip galvanizing muaj qhov zoo ntawm cov txheej sib xws, muaj zog lo thiab lub neej ntev. Cov yeeb nkab steel galvanized kub-dip raug cov tshuaj tiv thaiv lub cev thiab tshuaj lom neeg nrog cov kua plating molten los tsim cov txheej zinc-hlau alloy uas tiv taus corrosion nrog cov qauv nruj. Cov txheej alloy tau koom ua ke nrog cov txheej zinc ntshiab thiab cov yeeb nkab steel substrate, yog li nws muaj zog tiv taus corrosion.
Cov kav hlau galvanized kub-dip yog siv dav hauv kev tsim kho, tshuab, cov chaw tsuas thee, tshuaj lom neeg, hluav taws xob, tsheb ciav hlau, kev lag luam tsheb, txoj kev loj, choj, thawv, chaw ua si, tshuab ua liaj ua teb, tshuab roj av, tshuab nrhiav, kev tsim kho tsev cog khoom thiab lwm yam kev lag luam tsim khoom.

Lus Cim: Cov khoom siv kho tshuab ntawm cov hlau yog ib qho cim qhia tseem ceeb kom ntseeg tau tias qhov kev ua tau zoo kawg ntawm kev siv (khoom siv kho tshuab) ntawm cov hlau, uas nyob ntawm cov tshuaj lom neeg sib xyaw thiab kev kho cua sov ntawm cov hlau. Hauv cov qauv yeeb nkab hlau, cov khoom tensile (tensile zog, yield zog lossis yield point, elongation), hardness, toughness, thiab cov khoom kub thiab txias siab uas cov neeg siv xav tau yog teev raws li cov kev xav tau siv sib txawv.
