Flash taub qab vuam yog ib txoj kev siv dav rau kev koom nrog cov khoom siv hlau hauv ntau qhov kev lag luam.Txawm li cas los xij, ib qho teeb meem tshwm sim hauv cov txheej txheem no yog yellowing ntawm qhov chaw vuam.Qhov kev hloov pauv no tuaj yeem cuam tshuam tsis zoo rau qhov zoo thiab kev ncaj ncees ntawm cov vuam, ua rau nws yog qhov tseem ceeb los nrhiav kev daws teeb meem zoo los tiv thaiv lossis daws qhov teeb meem no.
Ua rau Yellowing:
Yellowing ntawm vuam qhov chaw nyob rau hauv lub pob tw vuam tuaj yeem raug ntaus nqi rau ntau yam.Qee qhov laj thawj tseem ceeb suav nrog:
- Oxidation:Kev raug oxygen ntau dhau thaum lub sijhawm vuam tuaj yeem ua rau tsim cov oxides ntawm cov hlau, uas ua rau yellowing.
- Thaum tshav kub kub thiab siab tsis txaus:Kev sib faib tsis sib xws ntawm cov cua sov thiab lub siab thaum lub sij hawm vuam tuaj yeem ua rau muaj xim tsis zoo hauv qee qhov chaw.
- Kev npaj khoom tsis txaus:Kev ntxuav tsis raug lossis tsis huv ntawm qhov chaw tuaj yeem ua rau yellowing thaum lub sij hawm vuam.
Cov kev daws teeb meem los tiv thaiv lossis chaw nyob daj:
Txhawm rau kom ntseeg tau tias qhov zoo tshaj plaws welds hauv flash pob tw vuam, cov kev daws teeb meem hauv qab no tuaj yeem siv los tiv thaiv lossis daws qhov teeb meem ntawm yellowing:
- Tswj Atmosphere:Vuam nyob rau hauv ib qho chaw tswj, xws li lub tshuab nqus tsev los yog ib qho chaw inert gas, tuaj yeem txo oxidation thiab txo qhov tsim ntawm oxides.Qhov no pab tswj lub ntuj xim ntawm cov hlau nto.
- Kev faib tawm cua sov thiab siab:Ua kom ntseeg tau tias muaj kev faib tawm ntawm cov cua sov thiab siab thoob plaws qhov chaw vuam yog qhov tseem ceeb.Qhov no tuaj yeem ua tiav los ntawm kev ua kom zoo dua cov vuam tsis zoo thiab siv cov khoom siv vuam zoo nrog kev tswj xyuas meej.
- Kev npaj cov khoom siv tau zoo:Ua tib zoo ntxuav thiab degrease cov hlau saum npoo ua ntej vuam.Kev npaj saum npoo kom zoo txo qhov kev pheej hmoo ntawm kev sib kis thiab txhawb nqa kev ua kom zoo dua qub thaum lub sijhawm vuam.
- Tom qab Weld Surface Treatment:Tom qab vuam, xav txog kev siv cov kev kho mob tom qab vuam, xws li pickling lossis passivation, kom tshem tawm cov oxides seem thiab rov qab zoo li qub ntawm cov hlau.
- Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb:Ua raws li kev tswj xyuas zoo thiab kev soj ntsuam xyuas kom paub meej tias muaj kev hloov xim tam sim ntawd.Kev txheeb xyuas sai tso cai rau kev kho sai sai.
- Kev xaiv khoom siv:Qee zaum, xaiv cov hlau uas muaj kev tiv thaiv zoo dua rau oxidation, xws li stainless hlau lossis lwm yam corrosion-resistant alloys, tuaj yeem pab txo cov teeb meem daj.
Hauv kev xaus, yellowing ntawm vuam qhov chaw nyob rau hauv lub pob tw vuam tshuab tuaj yeem tiv thaiv tau zoo lossis hais los ntawm kev sib xyaw ua ke ntawm cov khoom tsim nyog, tswj kev vuam, thiab kev kho tom qab vuam.Los ntawm kev siv cov kev daws teeb meem no, cov tuam ntxhab tuaj yeem ua kom ntseeg tau tias lawv cov pob qij txha welded ua tau raws li cov qauv kev xav tau zoo thiab tuav lawv qhov zoo li qub.
