1.How ua li cas ntawm lub substrate (steel chev) cuam tshuam rau qhov cuam tshuam tsis kam ntawm galvanized chev?
Tsawg cov pa hlau (hlau me):
Nta: Zoo plasticity thiab siab ductility.
Kev Cuam Tshuam: Thaum muaj kev cuam tshuam, nws nqus lub zog feem ntau ntawm cov yas deformation (yog kho hniav, khoov) es tsis yog pob txha. Yog li ntawd, nws muaj kev cuam tshuam zoo heev.
Cov ntawv thov: Cov ntawv thov feem ntau, xws li kev tsim kho thiab tsev khoom siv, uas yuav tsum tau ua kom muaj zog.
Lub zog loj hlau (hss) thiab siab lub zog tag nrho cov hlau (HSLA):
Nta: Lub zog siab dua yog ua tiav los ntawm kev sib ntxiv ntawm cov ntsiab lus thiab tswj dov thiab txias txheej txheem.
Kev Cuam Tshuam: Muaj Zog, tab sis Toubness thiab Ductility yog feem ntau qis dua cov ntawm cov hlau qis. Thaum muaj kev cuam tshuam, nws zoo li yauv tsis muaj kev puas tsuaj tsis zoo, tab sis muaj kev pheej hmoo ntawm brittle backstrure. Kev cuam tshuam cov qauv nruj yuav tsum ua raws cov qauv tshwj xeeb (xws li Charpy V - negch cuam tshuam lub zog).
Daim ntawv qhia tag nrho cov hlau:
Nta: tsis muaj zog thiab hardness ua tiav los ntawm ntau dua txias dov.
Kev cuam tshuam: heev tsis zoo. Kev ua kom qis kawg tsis tshua muaj zog ua rau nws muaj kev sib tsoo lossis tawg thaum cuam tshuam. Cov khoom siv no feem ntau yuav tsum tau muaj kev txhawb nqa kom rov ua kom nws muaj kev nruj ua ntej galvanizing.
2.Yowa lub galvanizing txheej cuam tshuam rau qhov cuam tshuam tsis kam ntawm galvanized coils?
Hydrogen embrittlement kev pheej hmoo (qhov kev txhawj xeeb tseem ceeb):
Txheej txheem: thaum lub sij hawm pickling (pre -} galvanizing) thiab electroplating cov txheej txheem, hydrogen atoms yuav nkag mus rau hauv cov hlau.
Kev cuam tshuam: Hydrogen atoms sib txuam hauv cov tawv ntoo, ua rau cov steel ua kom qeeb, ua rau ncua kev ntxhov siab thiab kev cuam tshuam ntse hauv kev cuam tshuam tsis kam.
Kev daws: Niaj hnub nimno Galvanizing cov txheej txheem, tshwj xeeb tshaj yog cov analing kauj ruam thaum lub hot}}} Dip Galrogen, muaj txiaj ntsig kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm hydrogen embrittlement. Yog li ntawd, txoj kev pheej hmoo ntawm hydrogen embrittlement nyob rau hauv kom tsim nyog ua hdg coils yog tsawg heev.
3.Qhov dab tsi ua tus yam ntxwv ntawm txheej nws tus kheej muaj ntawm qhov cuam tshuam tsis kam ntawm galvanized coils?
Cov txheej dawb huv zinc yog qhov muag thiab tsis nyuaj. Nws tuaj yeem nqus tau ib qho me me ntawm kev cuam tshuam lub zog los ntawm nws tus kheej kev tiv thaiv me me yog los tiv thaiv corrosion ntau dua li ua kom muaj tshuab cuam tshuam.
4.How nws ua li cas sib txawv hauv cov xwm txheej sib txawv?
Zoo li qub lossis qeeb thauj (xws li cov khoom ntim khoom):
Cov kev ua tau zoo ntawm Galvanized coils yog yuav luag zoo li ntawm lawv substrate. Lub zinc txheej muaj tsawg heev rau lawv lub tensile thiab tawm dag zog.
Kev cuam tshuam muaj zog (xws li dauv thiab kev sib tsoo):
Qhov Zoo: Cov tawv hlau tawv me me ua kom rov qab tuav cov kev xav tau zoo tom qab Galvanizing, ua rau cov tub rog qis dua li pob txha.
Tsis zoo:
Yog hais tias lub substrate yog siab - lub zog steel lossis muaj inherently tsis txaus, uas tuaj yeem ua qhov pib ntawm cov kab nrib pleb hauv substrate.
Thaum tsis tshua muaj kub, tag nrho cov hlau ua nkig. Cov nyhuv ntawm zinc txheej ntawm lub substrate todnuse yuav tsum tau ntsuas kev tshuaj tiv thaiv tshwj xeeb.
Tom qab tsim (xws li stamping thiab dabtsi yog khoov):
Cov ntaub ntawv twb tau deformed thaum lub sijhawm ua, thiab nws cov kev cuam tshuam cuam tshuam tuaj yeem hloov pauv hauv kev ua haujlwm - qhov chaw tawv. Txawm li cas los xij, yog hais tias lub zinc txheej tuaj yeem ua raws li kev deformation ntawm substrate, nws yuav muaj cov nyhuv me me ntawm qhov cuam tshuam ntawm qhov ua tiav.
5.Txhua qhov kev cuam tshuam tsis kam ntawm Galvanized coils?
Piav kom meej koj cov kev xav tau: Ua ntej, txiav txim siab qhov yuav tsum muaj kev cuam tshuam nyuaj theem raws li qhov kawg cov khoom lag luam ua haujlwm (txawm tias nws yuav txias lossis yuav tsum tau txias lossis ua rau muaj kev thauj khoom zoo).
Xaiv cov khoom siv sib xyaw ua ke: sab laj nrog koj tus neeg xa khoom hlau los xaiv cov qib kawm thiab qauv (xws li ASTM, JIS, lossis GB) uas tau raws li koj qhov yuav tsum tau ua. Rau cov cheebtsam tseem ceeb, thov kom them cov ntawv tshaj tawm hluav taws xob tsis zoo.
Xaiv cov txheej txheem galvanizing kev txhim khu kev qha: kub - dip galvanizing feem ntau muab cov ntsiab lus sib luag dua electring zog thiab hydrogen embrittlement.
Ua cov txheej txheem siv tau: ua ntej kev ua haujlwm loj, kev kuaj kab mob, thiab lwm yam kev kuaj kom paub tseeb tias cov khoom siv galvanized ua tau raws li koj cov kev cai ua thiab daim ntawv thov.
