Taw qhia rau cov kev sib txawv ntawm ntau hom ntawm etching

Stainless Hlau etching:

Tsis zoo li tooj liab los yog aluminium alloys, stainless hlau tsis yooj yim oxidized rau hauv huab cua, uas tsis muaj kev kho mob ua ntej yooj yim dua li cov tooj liab thiab aluminium alloys. Lub caij no, hlau Stainless muaj qhov ruaj khov nyob rau hauv cov kev daws teeb meem alkaline tuaj yeem siv rau kev kho mob saum npoo av, thiab tau kawg, acidic tu cov neeg sawv cev kuj tseem tuaj yeem siv rau kev ntxuav. Muaj cov cav etching thiab txau etching txoj kev rau cov hlau stainless. Yog tias yuav tsum muaj rau qhov tob ntawm qhov muag ntawm cov khoom, tsuag etching tuaj yeem xaiv; Ntawm qhov tsis sib xws, yog hais tias etching qhov tob ntawm cov khoom yog tsis siab, soaking txoj kev tuaj yeem xaiv.

Muaj ob tus qauv rau kev etching cov kev daws teeb meem ntawm cov hlau stainless:
① Cov tshuaj etching tsuas yog siv feem ntau ntawm etching factories yog kev ua tau zoo, sulfor acid, benzotriazole, urotropine, thiab acid dolts, thiab acid salts;
② Ib txoj hlab dej etching npaj nrog nitric acid, hydrochloric acid, thiab phosphoric acid. Tom qab no etching daws tau npaj, nws xav tau kom muaj hnub nyoog nrog cov hlau mos thiab tom qab ntawd nws tau kho rau cov txheej txheem ntau yam kev tsom xam cov txheej txheem.

Tooj liab Etching:
 Tooj liab etching tuaj yeem siv tau sib txuas nrog nrog stainless hlau tov. Tooj liab ntau dua li cov hlau thiab tuaj yeem txo cov hlau ions, yog li etching tooj liab tsis xav tau tov; Cov kua mis raug tshem tawm kuj siv cov alkali muaj zog, tab sis tooj liab muaj zog ntau dua rau oxidation thiab yuav tsum muaj kev kho mob kom tsis txhob muaj kev tshem tawm. Yog li tooj liab etching txheej txheem yog cov ntau dua li cov txheej txheem hlau tsis muaj tseeb;

 Muaj kev ywj pheej zoo ntawm kev ywj pheej hauv kev xaiv ntawm etching cov kev daws teeb meem rau tooj liab thiab cov alloys. Feem ntau siv cov tshuab etching suav nrog peb qhov chaw tsim hluav taws xob etching system etching copposide etching system etching system, thiab sulfuric acid hydrogen peroxide etching system. Peb lub chaw tsim hluav taws xob etching system thiab alkaline tooj liab chloride etching system yog feem ntau siv. Nyob rau hauv cov tshuab etching, sulfuric acid hydrogen peroxide etching system yog qhov yooj yim rau kev tsim nyog, thiab tooj hauv qhov kev daws teeb meem etching tseem yooj yim. Txawm li cas los xij, vim qhov tsis muaj zog ntawm nitrogen peroxide, nws tsuas yog txwv nyob rau hauv kev siv kev tsim. Txawm hais tias Ferric chloride etching system ua rau muaj kev npaj ib puag ncig high, nws tau siv tau yooj yim, tus nqi qis, thiab tswj hwm yooj yim.

Aluminium etching:
 Cov kev sib nqus tshwj xeeb ntawm kev daws teeb meem uas yuav tsum tau rau txhuas etching yog tsawg, thiab nws reactsects ua txhaum nrog kev daws teeb meem, tso tawm ntau npaum li cas ntawm kev kub. Qhov tsis tshua muaj lub ntiajteb txawj nqus tau qeeb txoj kev tshwm sim. Kev daws rau etching aluminium muaj qhov tsis tshua muaj lub ntiajteb txawj nqus thiab txo cov tshuaj pov tseg me me tsuas yog tso tawm. Yog li ntawd, etching Aluminium noj ntau npaum li cas ntawm cov tshuaj thiab ua ntau cov dej dej. Aluminium Ink Tshem Tawm yuav tsum nitric acid, hydrofluoric acid, thiab lwm yam pa luam yeeb, thiab cov pa roj ntsha tuab, thiab cov txheej txheem yog cov txheej txheem sib txawv.

 Cov txheej txheem etching rau alloys alloys muaj cov acidic thiab alkaline, nrog ferric acid tau siv ntau yam li cov acidic etching tshuab, thiab phosphate monofluoride tseem siv. Ntawm lawv, daim ntawv thov ntawm ferric chloride etching system yog ib qho. Qhov kev etching zoo ntawm alkaline etching yog qhov zoo dua li ntawm ferric chloride, thiab etching tus nqi yog qis dua, ua rau nws zoo dua etching txoj kev. Txawm li cas los xij, tus nqi tsim ntawm cov txheej txheem los tiv thaiv corrosion ntawm almaline etching, uas tam sim no tus neeg siv hluav taws xob muaj kev txwv ntawm Alkaline etching.
