Hardness yog ib qho khoom siv feem ntau siv hauv cov khoom siv hlau.Covhlau hlau Hoobkasqhia txoj kev sim ceev thiab kev lag luam rau kev sim hardness.Txawm li cas los xij, rau qhov nyuaj ntawm cov khoom siv hlau, tsis muaj kev sib koom ua ke thiab cov ntsiab lus meej nrog rau txhua txoj hauv kev sim hauv tsev thiab txawv teb chaws.Feem ntau, qhov nyuaj ntawm cov hlau feem ntau suav hais tias yog cov khoom siv rau cov yas deformation, khawb, hnav, lossis txiav.
Loj kaujgalvanized hlaunyob rau hauv zinc immersion deb debugging, ua kom tus thawj ceev tsis hloov, raws li t = KD los txiav txim lub zinc immersion lub sij hawm (1), qhov twg: t yog zinc immersion lub sij hawm tas li, noj 4-7D yog txoj kab uas hla ntawm steel hlau mm , thiab tom qab ntawd kwv yees cov zinc immersion nrug.Los ntawm kev kho cov zinc dip nrug, zinc dip lub sij hawm ntawm steel hlau ntawm ntau yam specifications yuav luv luv los ntawm 5s nyob rau nruab nrab.Nyob rau hauv txoj kev no, zinc noj ib tuj ntawm steel hlau txo los ntawm 61kg txog 59.4kg.
Kub dip galvanizing yog nyob rau hauv kub yaj zinc kua dip plating, ntau lawm ceev, tuab tab sis tsis sib xws txheej, kev ua lag luam tso cai rau lub thickness ntawm 45 microns, mus txog 300 microns saum toj no.Nws yog xim tsaus nti, siv zinc hlau ntau dua, cov ntaub ntawv infiltration txheej nrog lub hauv paus hlau, thiab muaj corrosion kuj zoo.Kub dipgalvanizingtuaj yeem khaws cia rau ntau xyoo hauv qhov chaw sab nraum zoov.Kev tiv thaiv zinc txheej ntawm hlau matrix muaj ob lub hauv paus ntsiab lus: ntawm ib sab, txawm hais tias zinc muaj zog dua thiab yooj yim rau oxidize dua hlau, tab sis nws cov oxide zaj duab xis tsis yog xoob thiab compact li hlau oxide.Qhov ntom oxide txheej tsim rau ntawm qhov chaw inhibits ntxiv oxidation ntawm zinc nyob rau hauv sab hauv.
Tshwj xeeb tshaj yog tom qab passivation ntawm galvanized txheej, nto ntawm oxide txheej yog thicker thiab compact, nws tus kheej muaj siab oxidation kuj.Ntawm qhov tod tes, thaum nto ntawm lubgalvanizedtxheej txheej puas lawm, nthuav tawm cov hlau sab hauv matrix, vim zinc muaj zog dua hlau, zinc yuav dais lub luag haujlwm ntawm kev txi zinc anode, zinc yuav oxidized ua ntej hlau, thiaj li tiv thaiv cov hlau txheej yuav tsis puas.
