Kev lag luam txhuas profile hauv Chongqing tau tsim kho sai heev nyob rau xyoo tas los no, thiab maj mam ntsib thoob plaws lub tebchaws. Kev siv tshuab anodizing yog ib qho ntawm cov txheej txheem siv ntau hauv kev lag luam txhuas profile hauv Chongqing. Ntau tus neeg siv tshiab tsis paub ntau txog cov txheej txheem anodizing, yog li cia peb muab cov lus qhia ntxaws ntxaws rau koj.
Cov txheej txheem ntws ntawm kev kho oxidation rau cov khoom siv txhuas hauv Chongqing;
1. Kev kho qhov chaw.
Kev kho qhov chaw, tseem hu ua kev kho ua ntej ntawm qhov chaw, yog tshem tawm cov av ntawm qhov chaw ntawm cov txhuas profile los ntawm kev siv cov tshuaj lom neeg thiab cov khoom siv, kom nws tuaj yeem raug rau lub cev txhuas profile, uas yooj yim rau kev kho oxidation ntawm qhov chaw ntawm cov txhuas profile hauv theem tom qab.
2. Cov txheej txheem degreasing nto.
Lub hom phiaj ntawm cov txheej txheem degreasing yog tshem tawm cov roj nplua nyeem hauv kev lag luam, cov roj tiv thaiv xeb thiab cov av qias neeg uas lo rau ntawm qhov chaw ntawm cov txhuas profile, kom ntseeg tau tias cov txhuas profile muaj kev xeb alkali sib xws thiab kev huv ntawm cov alkali corrosion tank. Txhim kho qhov zoo ntawm cov txhuas profile.
3. Cov txheej txheem etching acid.
Cov txheej txheem etching acid ntawm qhov chaw yog ua tiav kev kho mob acid etching tom qab tshem cov roj ntawm cov txhuas profile, thiab lub hom phiaj tseem ceeb ntawm kev tshem tawm yog tshem tawm cov oxide uas tsim los ntawm kev oxidation ntawm lwm cov hlau ntawm qhov chaw ntawm cov txhuas profile thiab cov zaj duab xis oxide uas tsim los ntawm cov profile; Tom qab kev kho mob acid corrosion, nws yog ib qho tsim nyog los ntxuav nws tam sim ntawd, thiab qhov kub ntxuav yuav tsum tau tswj 50 ℃ ua ntej kom tsis txhob muaj cov cim ntws ntawm qhov chaw ntawm cov profile, thiab tom qab ntawd ntxuav nws nrog dej ntws. Vim tias cov txhuas profile muaj tooj liab, qhov chaw yuav tsaus tom qab kev kuaj acid corrosion, thiab nws yuav tsum tau muab tso rau hauv cov kua qaub nitric rau 3-5 feeb kom ua rau qhov chaw ci nyiaj.
4. Cov txheej txheem alkaline etching.
Lub hom phiaj tseem ceeb ntawm cov txheej txheem alkali etching yog tshem tawm cov khoom seem thiab cov txheej metamorphosed ntawm qhov chaw ntawm cov txhuas profile thaum lub sijhawm oxidation, thiab tshem tawm cov khawb tsis zoo uas tshuav ntawm qhov chaw ntawm cov txhuas profile thaum lub sijhawm kneading. Kev kho alkaline etching ntawm qhov chaw ntawm txhuas profile ua lub luag haujlwm tseem ceeb hauv qhov zoo ntawm txhuas profile.
5. Cov txheej txheem neutralization.
Lub hom phiaj ntawm cov txheej txheem neutralization yog tshem tawm cov khoom sib xyaw lossis cov khoom tsis huv xws li tooj liab, manganese, hlau, silicon, thiab lwm yam uas tsis yaj hauv cov kua alkaline uas tshuav ntawm qhov chaw ntawm txhuas profile tom qab acid etching thiab alkali etching. Feem ntau, txoj kev neutralization ntawm cov kua alkaline uas tshuav ntawm txhuas profile tom qab alkali etching yog siv 30% -50% nitric acid kua. Rau cov hlau txhuas high-silicon, cov kua qaub sib xyaw ntawm nitric acid thiab hydrogen fluoride nrog qhov ntim piv ntawm 1: 3 raug xaiv. Silicon reacts nrog hydrogen thiab hydrofluoric acid los tsim cov kua fluosilicic, uas tawm ntawm qhov chaw txhuas.
6. Kev kho mob anodizing.
Txoj kev kho anodic oxidation yog tias cov tshuaj siv ua qhov nruab nrab, thiab qhov tawm ntawm lub taub hau raug xaiv los tsim cov zaj duab xis oxide rau ntawm qhov chaw ntawm txhuas profile, yog li ntawd txhuas profile muaj kev tiv thaiv corrosion super. Vim tias cov txheej tiv thaiv tau los ntawm anodic oxidation ntawm txhuas profile muaj qhov nyuaj thiab tiv thaiv corrosion siab dua, qhov tuab txheem yog 10-12μ m, uas tuaj yeem txhim kho qhov tiv thaiv oxidation ntawm txhuas profile thiab qhov zoo nkauj ntawm txhuas profile.
Cov txheej txheem anodic oxidation ua lub luag haujlwm tseem ceeb hauv kev zoo nkauj thiab kev ruaj khov ntawm Chongqing industrial aluminium profiles.
