Tshuaj etching ntawm hlau txhais tau tias tshem tawm cov flux lossis oxide residues ntawm nws qhov chaw. Cov txheej txheem zoo li no suav nrog kev siv cov tshuaj chloride ntsev, alkali lossis kua qaub. Txawm hais tias siv cov tshuaj phem npaum li cas, hlau etching yuav tsum tau ceev faj heev thiab raug los ntawm ib tug neeg, vim hais tias cov tshuaj no yog heev txaus ntshai thiab yuav ua rau cov tshuaj burns yog hais tias lawv mus rau ntawm daim tawv nqaij. Txawm li cas los xij, nrog kev npaj kom raug, cov txheej txheem no tuaj yeem nqa tawm hauv tsev. Hlau etching tso cai rau koj rov tsim dua ib qho kev piav qhia, ntawv nyeem, qhov tob lossis kev kho kom zoo nkauj ntawm yuav luag txhua qhov chaw hlau. Cov khoom tau txais txiaj ntsig tiag tiag siv sijhawm los kawm txog cov thev naus laus zis no.

Lub ntsiab ntawm txheej txheem

Txhim kho cov hlau tuaj yeem ua tiav, uas feem ntau yog siv los ntxuav yooj yim, lossis ib nrab, uas feem ntau siv los kho cov khoom. Thaum kawgHauv qhov no, txhawm rau tiv thaiv thaj chaw uas yuav tsum tsis txhob raug kev kho mob zoo li no, siv lub npe hu ua tiv thaiv. Pickling ntawm cov hlau tuaj yeem ua tau tshuaj lom neeg lossis galvanically. Nyob rau hauv thawj rooj plaub, cov khoom yog immersed nyob rau hauv ib tug tov. Lub sijhawm ua haujlwm yog nyob ntawm qhov xav tau qhov tob etch thiab hom khoom nws tus kheej. Tom qab rho tawm, cov hlau yog ntxuav kom huv si nrog dej txias, uas qee zaum ntxiv cov kua dej qab zib. Ua tsaug rau qhov no, koj tuaj yeem paub tseeb tias cov kua qaub yuav tsis lwj qhov tshwm sim.

Nws tau siv nyob rau hauv Nruab Nrab Hnub nyoog los kho cov riam phom thiab cuab yeej cuab tam. Nyob rau hauv cov nqe lus ntawm lawv kev zoo nkauj, xws li cov khoom yog feem ntau tsis inferior mus rau lub creation ntawm txhais tes ntawm txawj jewelers. Rau hom kev kho hlau saum npoo no, txoj kev thib ob, uas yog, txoj kev galvanic, yog qhov zoo tshaj plaws. Txoj kev no zam kev tso tawm cov pa roj uas tsim kev puas tsuaj rau tib neeg, uas tshwm sim thaum lub sijhawm ua tshuaj lom neeg, thiab muaj txiaj ntsig zoo dua, vim nws ua rau nws tuaj yeem ua rau cov npoo ntawm cov qauv etched ntau qhov txawv.

Kev xyaum ua haujlwm

txhawm rau qhia koj lub peev xwm thiab pib cov txheej txheem no hauv tsev, thawj qhov koj yuav tsum tau ua yog nrhiav DC qhov chaw, qhov hluav taws xob uas yog kwv yees li ntawm 4-7 Volts. Qhov kev xaiv zoo tshaj plaws yog lub tsev siv hluav taws xob siv hluav taws xob nrog kev hloov pauv. Tom qab ntawd koj yuav tsum tau da dej ntawm cov khoom siv insulating, uas yuav muaj cov electrolyte. Raws li yav tas los, ib qho kev daws teeb meem ntawm cov ntsev zoo tib yam tuaj yeem siv tau, tab sis feem ntau yog rau qhov noCov hom phiaj siv ib qho kev daws teeb meem ntawm vitriol. Hlau yog siv rau hlau thiab hlau, thiab tooj liab yog siv rau tooj liab, tooj dag thiab tooj.

Hlau billet yuav tsum tau degreased ua ntej. Ua li no, solder ib tug tooj liab xaim rau nws, tuav nyob rau hauv uas nws yog txo rau 5 feeb rau hauv ib tug tov ntawm caustic sodium, rhuab mus rau ib tug kub ntawm 50 ° C. Tom qab ntawd lub workpiece raug xa mus rau ob peb feeb rau hauv cov kua nrog 15% sulfuric acid cov ntsiab lus, tom qab ntawd nws yog huv si ntxuav nrog dej kub. Qhov kev npaj kawg yog qhov kev npaj ntawm mastic. Nyob rau hauv ib lub thawv, sib tov var, rosin thiab ciab nyob rau hauv ib tug ratio ntawm 4: 2: 3 thiab yaj kom txog thaum ib homogeneous loj tau txais. Thaum nws txias lawm, qhwv nws nyob rau hauv ib tug muaj zog, nyias daim ntaub thiab khiav tshaj lub rhuab me ntsis workpiece kom txog rau thaum nws yog them nrog ib tug nyias txheej. Tom qab tag nrho cov no tau hardened, siv cov qauv xav tau nrog cov xim dej thiab txhuam tawm cov mastic nrog rab riam qhov twg cov indentations yuav tsum yog. Tam sim no muab nws tso rau hauv electrolyte los ntawm kev sib txuas ntawm lub davhlau ya nyob twg nrog tus ncej zoo rau nws, thiab dai ib qho khoom siv hlau los ntawm cov hlau nrog lub cim rho tawm thiab tseem txo qis rau hauv electrolyte. Tom qab ua tiav cov pickling, desolder cov hlau, yaug lub resulting masterpiece nrog turpentine thiab ua qhov kawg finishing (sib tsoo thiab polishing).
