Cov ncauj lus kom ntxaws qhia txog Galvanized Steel Yeeb Nkab

Kub dip galvanized yeeb nkab
Kub dip galvanized kav yog tsim los ntawm reacting molten hlau nrog ib tug hlau substrate los tsim ib tug alloy txheej, yog li combining lub substrate thiab txheej. Kub dip galvanizing yog hais txog kev xaiv cov kav hlau ua ntej. Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov kav dej steel, tom qab pickling, cov kav hlau steel raug ntxuav hauv ammonium chloride los yog Zinc chloride aqueous tov los yog tov ammonium chloride thiab Zinc chloride aqueous tov tank, thiab ces xa mus rau kub dip plating tank. Kub dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion, thiab lub neej ua haujlwm ntev. Lub substrate ntawm kub-dip galvanized steel kav ua rau lub cev thiab tshuaj lom neeg cov tshuaj tiv thaiv nrog cov molten plating tov, tsim ib tug corrosion-resistant thiab nruj nreem txheej zinc hlau alloy txheej. Cov txheej txheej hlau yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel substrate, yog li nws cov corrosion kuj muaj zog.
Cold galvanized yeeb nkab
Cov kav dej txias galvanized yog galvanized los ntawm hluav taws xob, nrog me me ntawm galvanizing, tsuas yog 10-50g / m2, thiab lawv cov corrosion kuj txawv ntawm cov kav dej kub-dip galvanized. Feem ntau cov galvanized yeeb nkab manufacturers tsis siv hluav taws xob galvanizing (txias plating) kom zoo. Tsuas yog cov lag luam me nrog cov khoom siv tsis tu ncua thiab cov nplai me me siv electrogalvanizing, thiab tau kawg, lawv cov nqi kuj pheej yig dua. Lub Tsev Haujlwm Saib Xyuas Kev Tsim Kho tau tshaj tawm tias cov kav dej txias galvanized nrog rov qab thev naus laus zis yuav raug tshem tawm, thiab cov kav dej txias galvanized tsis raug tso cai siv los ua cov kav dej thiab roj. galvanized txheej ntawm txias galvanized steel kav yog ib txheej electroplating, uas yog nws tus kheej txheej nrog cov yeeb nkab steel substrate. Cov zinc txheej yog nyias nyias thiab tsuas yog ua raws li cov yeeb nkab steel substrate, ua rau nws yooj yim poob. Yog li ntawd, nws cov corrosion kuj tsis zoo. Hauv cov tsev tsim kho tshiab, nws raug txwv tsis pub siv cov kav dej txias galvanized ua cov kav dej.

Lus Cim: Cov khoom siv kho tshuab ntawm cov hlau yog cov cim tseem ceeb los xyuas kom meej qhov kev siv tau zoo tshaj plaws (cov khoom siv tshuab) ntawm cov hlau, uas nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov ntawm cov hlau. Nyob rau hauv cov qauv steel yeeb nkab, tensile zog (lub zog tensile, yield zog los yog yield point, elongation), hardness thiab toughness indicators, as well as high and low temperature properties, as well as the different use requirements.
