Thaum muaj coob tus neeg siv cov liabdaim ntawv tooj
, lawv yuav pom tias qhov chaw ntawm daim ntawv liab tooj liab muaj tev lossis dents.Daim ntawv tooj liab liab muaj hluav taws xob zoo, thermal conductivity, corrosion kuj thiab kev ua haujlwm, thiab tuaj yeem welded thiab brazed.Cov tev lossis lub qhov dej no tsis tuaj yeem siv.Rau vuam, daim ntawv tooj liab yog tev tawm thiab siv tsis tau, uas yuav ua rau tag nrho cov phaj khib nyiab ntau ntau.Tom ntej no, cia peb saib cov kev txheeb xyuas ntawm cov laj thawj ntawm kev tev ntawm daim ntawv tooj liab.
Thaum muaj coob tus neeg siv lub phaj tooj liab liab, lawv yuav pom tias qhov chaw ntawm daim ntawv tooj liab liab muaj tev lossis dents.Daim ntawv tooj liab liab muaj hluav taws xob zoo, thermal conductivity, corrosion kuj thiab kev ua haujlwm, thiab tuaj yeem welded thiab brazed.Cov tev lossis lub qhov dej no tsis tuaj yeem siv.Rau vuam, daim ntawv tooj liab yog tev tawm thiab siv tsis tau, uas yuav ua rau tag nrho cov phaj khib nyiab ntau ntau.Tom ntej no, cia peb saib cov kev txheeb xyuas ntawm cov laj thawj ntawm kev tev ntawm daim ntawv tooj liab.
1. Cov txheej galvanized tsis ua kom huv.Siv cov concentrated hydrochloric acid thiab hydrogen peroxide los tev tawm cov txheej txheem passivated galvanized.Ntau tus phooj ywg kho vajtse feem ntau ntsib tias cov khoom siv zinc alloy yog plated nrog cov txheej txheej tawg tom qab ironing cov ntawv hlau., yog vim li cas.
2. Lub tev tawm ntawm cov ntawv hlau galvanized qhia tau hais tias cov adhesion ntawm cov txheej yog tsis zoo, uas yog feem ntau tshwm sim los ntawm kev kho tsis raug ua ntej electroplating.Cov txheej txheem degreasing thiab degreasing yuav tsum tau kuaj xyuas kom pom tias cov degreasing tiav lawm.Tsis tas li ntawd, kev kho corrosion tsis muaj zog yuav tsum tau ua ua ntej electroplating, thiab lub workpiece yuav tsum tau electroplated tam sim ntawd tom qab tsis muaj zog corrosion, thiaj li hais tias cov adhesion ntawm cov txheej ntawm cov tshiab thiab active nto yuav zoo dua.
3. Nyob rau hauv cov txheej txheem ntawm kev ua, nws yuav tsum mus los ntawm ob peb txheej txheem dov.Nyob rau hauv txhua txoj kev, yog tias qhov chaw tsis huv, yuav muaj oxides txuas rau saum npoo ntawm lub phaj tooj liab.Tom ntej no dov yuav muab dov rau ntawm lub phaj tooj liab, uas ua rau cov phaj tooj liab tau ua tiav hauv cov khoom tiav.Cov oxide ntog tawm, uas ua rau cov pits, pitting, thiab lwm yam tsis xws luag.
4. Thaum lub sij hawm ua, qhov kub thiab txias yog siab dhau, thermal expansion coefficient ntawm cov hlau yog txawv, kev tu ntawm electroplating nto tsis zoo, thiab cov tooj liab txheej yog tuab heev.
5. Vim tias tsis muaj kev ntim khoom ntim thaum lub sijhawm thauj mus los, qhov sib txawv ntawm cov phaj tooj liab thiab cov phaj tooj liab yog qhov loj heev.Tom qab ntawd nyob rau hauv cov txheej txheem ntawm kev thauj mus los, vim lub tsheb pob thiab lwm yam kev mob, kev sib tsoo nto thiab kev sib txhuam yog tshwm sim!Lub phaj tooj liab nws tus kheej yog cov hlau mos, thiab nws yuav inevitably tev tawm hauv kev sib tsoo thiab kev sib txhuam.
Muaj ib qho tshwm sim ntawm bubbling ntawm lub phaj tooj liab thiab txheej tooj liab.Ua ntej tshaj plaws, peb yuav tsum txiav txim siab los ntawm qhov yooj yim mus rau qhov nyuaj.Ua ntej, peb yuav tsum saib seb puas muaj kev ua haujlwm.Kho qhov ua kom cov tshuaj, qhov ua kom zoo thiab yuav tsis muaj foaming.
