Taw qhia rau Hlau etching txheej txheem ntws

Cov txheej txheem etching ntawm ntau hom ntawm cov hlau sib txawv, tab sis cov kauj ruam dav dav yog raws li hauv qab no:

Hlau etching phaj → Degreasing → Dej ntxuav → Cov ntaub ntawv ntxuav → Cov ntaub ntawv ntxuav → Dej ntxuav → Cov ntaub so kom sov Polishing (Polishing) → Txau Pob tshab Xim → Kom Qhuav → Kev Ntim Khoom Siv → Tiav Ntim Ntim.

1. Pre etching kho
Cov txheej txheem ua ntej cov hlau etching yog kev kho mob ua ntej, uas yog ib txoj kev tseem ceeb los xyuas kom zoo adkesion ntawm silk npo memk thiab daim npog ntsej muag hlau. Yog li ntawd, nws yog ib qho tsim nyog los kom huv si tshem cov roj stains thiab oxide zaj duab xis ntawm cov hlau etching nto. Cov phiaj xwm kev tshem tawm roj yuav tsum tau txiav txim siab raws cov roj paug ntawm cov haujlwm hluav taws xob tsis huv ntawm kev tshuaj ntsuam xyuas cov roj hluav taws xob kom ntseeg tau. Qhov zoo tshaj plaws etching daws yuav tsum tau xaiv raws li hom hlau thiab cov tuab ntawm cov yeeb yaj kiab oxide kom ntseeg tau kom huv si. Ua ntej kev luam ntawv, nws yuav tsum tau qhuav. Yog tias muaj cov dej noo, nws tseem yuav cuam tshuam cov kua mem kua txiv, thiab txawm cuam tshuam cov nyhuv ntawm cov qauv tom ntej thiab distortion, cuam tshuam rau cov nyhuv zoo nkauj.
2. Vijtsam Luam Ntawv
Luam tawm luam ntawv yuav tsum tau tsim cov qauv txheem duab kos duab luam ntawv cov ntxaij vab tshaus raws li kev luam ntawv. Nyob rau hauv cov txheej txheem ntawm cov qauv kho kom zoo nkauj, tshuaj ntsuam kev lag luam tsuas yog lub luag haujlwm tiv thaiv kev tiv thaiv. Thaum ua ntawv thov cov nplaum, nws yog qhov tsim nyog yuav tsum tau thov ntau zaus nyob rau hauv thiaj li yuav txhim kho cov qauv siv cov khoom siv thicker thiab etch qauv nrog cov ntsiab lus siab. Cov nplaum ua yeeb yaj kiab ntawm lub phaj tawg hauv qhov kev txiav txim siab ntawm lub teeb, yog li cov qauv kev ua yeeb yaj kiab, ua rau pom kev zoo nkauj ua yeeb yaj kiab, ua rau pom kev sib dhos rau cov xim av, ua rau pom kev ua yeeb yaj kiab uas tsis pom zoo
Txhim kho lub vijtsam lo lo ntxhuav nrog cov qauv ntawm lub vijtsam luam ntawv, siv cov qauv tshuaj tiv thaiv cov qauv hauv cov hlau uas xav tau, thiab tom qab ziab, nws tuaj yeem etched.
3. Post Etching Kev Kho Mob
Tom qab etching, cov kab xev silk yuav tsum tau muab tshem tawm. General acid resistant number case yog yooj yim soluble hauv alkali. Kev tshem tawm lub phaj etching nyob rau hauv sodium hydrocide tov ntawm {} g \/ l ntawm qhov kub ntawm {1}} degree rau ob peb feeb kom tshem tawm tus mem kua. Tom qab tshem tawm, yog tias yuav tsum muaj lub teeb ci ntsa iab, nws tuaj yeem ua polished thiab tom qab ntawd dyed. Tom qab dylying, kom tiv thaiv kev sib txawv thiab nce hnav thiab corrosion tsis kam, pob tshab cov xim tha xim tuaj yeem tau txau. Txog qee cov hlau uas muaj cov xim zoo tiv thaiv thiab tsis txhob pleev xim pob txha, pob zeb tawv tuaj yeem siv tsis tau, nyob ntawm cov kev xav tau tiag tiag.
