Kub-dip galvanizing defects Kub-dip galvanizing muaj qee qhov cuab kev tsis zoo vim cov me me ntawm cov flange ceev, cov duab tsis zoo, thiab qee qhov xav tau rau cov xov lag luam.
1, ntsia hlau xov tom qab plating nyuaj. Tom qab kub-dip galvanizing, qhov ntxiv zinc sticks hauv xov thiab tsis raug muab tshem tawm yoojyim, thiab lub thickness ntawm zinc txheej yog tsis ncaj, uas cuam tshuam cov phom ntawm txoj hlua. Nws tau npaj tseg hauv GB / T13912-1992 "Cov Kev Ntsuam Xyuas Cov Kub-Dhau Galvanizing ntawm Cov Khoom Hlau Hlau" thiab GB / T2314-1997 "Kev Siv Tiav Yam Yuav Tsum Tau Ua Fais Fab"; cov khoom sab nraud ntawm sab nraud yuav tsum tau muab tso ua ntej kub dip plating raws li GB196 Tus qauv qhia txog kev ua haujlwm los yog tanning, thaum lub xov tooj hauv lub cev yuav ua tiav ua ntej los yog tom qab kub dip txheej. Txawm li cas los, hauv kev xyaum, cov neeg muas zaub feem ntau xav tau tias sab hauv thiab sab nraud threads muaj ib cov txheej txheej, yog li cov neeg siv ntau yam kev ntsuas los daws qhov teeb meem ntawm kub dip galvanizing ntawm threaded fittings. Xws li txoj hlua rov qab tom qab plating; tshwj tseg nrog kev sib txawv loj; Centrifugal tsis ua haujlwm thiab lwm txoj kev. Tom qab nres tau yooj yim puas rau ntawm qhov txheej ntawm lub txheej, lossis txawm tias las ntswj cov hlau substrate, ua rau khib nyiab corrosion. Ua kom zoo tshaj qhov ntau ntawm cov txiv ntsej muag lossis cov khoom siv kom ruaj ntseg, nws yooj yim kom txo tau lub zog zoo, uas tsis tau tso cai rau siab siv.
2. Kub dip galvanizing ua haujlwm ntawm kev kub muaj peev xwm, uas txo cov neeg kho tshuab zog ntawm high-strength flange neeg rau. Tom qab 8.8 qib bolts, lub zog ntawm qee cov xov tom qab kub-dip galvanizing yog qis tshaj qhov tsim nyog; tom qab 9.8 qhab nees, lub zog ntawm cov kub-dip galvanized bolts yeej tsis tuaj yeem ua raws li cov kev cai.
3, tsis zoo ua haujlwm, muaj pa phem heev. Kev sib txuas lus kub-dip galvanizing txheej txheem ntawm kev kub ntxhov, hnyav ziab thiab zinc leaching mus rau hauv lub pas dej ua thaum lub workpiece yuav plated yuav precipitate ib tug muaj zog irritating hydrogen cov ntaubntawv roj; zinc pas dej yog nyob rau hauv high temperature rau ib lub sij hawm ntev, zinc pas dej ua zinc chav, qhov chaw ntawm tag nrho cov chaw ua haujlwm tsis zoo.
Txawm hais tias kub-dip galvanized fasteners muaj ntau yam tsis xws luag, qhov kub-dip galvanized txheej muaj zoo tuab, qhov ua kom zoo zog, thiab cov nyom ntev. Lub zog hluav taws xob, kev sib txuas lus thiab cov tsheb thauj mus los yeej ib txwm tau raug fwm.
Nrog rau kev tsim hluav taws xob thiab kev thauj mus los hauv Suav teb, kev tsim cov kub ntub sab galvanizing ntawm flange ceev yuav nce. Yog li ntawd, kev tsim cov khoom centrifugal tsis siv cov khoom, kev txhim kho kub dip galvanizing txheej txheem rau cov kev sib tw, thiab kev txhim kho ntawm qhov kub kub dip galvanized coatings rau fasteners Tseem ceeb heev.
