Hlau Etching: Theory thiab kev xyaum

Tshuaj etching txhais tau tias tshem cov hlau los ntawm nws saum npoo lub oxides los yog flux residues. Xws li ib tug txheej txheem yuav siv cov kev daws ntawm tshuaj dawb ntsev ntawm alkali los yog acid tshuaj. Txawm li cas los zoo li cas ntawm nruj tshuaj ua hauj lawm yog siv, cov etching ntawm co yuav tsum tau lub utmost ceev faj thiab tib neeg cov neeg, txij thaum xws tshuaj yog txaus ntshai thiab nyob rau hauv kev sib cuag nrog cov tawv nqaij yuav ua rau kub yus. Cuaj kaum, nrog rau cov kev npaj ntawm tus txheej txheem nws yog tau mus nqa tawm nyob rau hauv tsev. Hlau etching tso cai rau cov me nyuam txawm zaj dab neeg, cov phau ntawv, qhov tob los yog nyem txog yam tshiab nyob zoo tej hlau nto. Cov khoom uas yog cov kev tshwm sim tiag tiag tsim nyog nws mus devote ib co dawb lub sij hawm kawm no technology.

Lub essence ntawm tus txheej txheem

Hlau etching yuav tsum yog tag nrho, uas yog feem ntau yog siv rau ib qho yooj yim purification thiab ib nrab, uas yog feem ntau siv rau cov kho kom zoo nkauj ntawm cov khoom. Nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv, los tiv thaiv tej qhov chaw uas yuav tsum tsis txhob raug rau qhov kev kho no, ib tug thiaj li hu ua thaum nws. Hlau etching yuav ua tau yog sib los yog galvanically. Nyob rau hauv rooj plaub thawj cov khoom los immersion rau hauv cov tshuaj. Cov kev kho mob lub sij hawm nyob rau hauv lub xav tau etching tob thiab lub hom ntawm cov khoom. Tom qab tshem cov hlau ntxuav kom huv si nrog dej txias, uas tej zaum kuj ntxiv ib qho aqueous tov ntawm dej qab zib. Qhov no ua rau nws tau mus yuav nco ntsoov hais tias ib co kua nplaum ntawm acid yuav tsis lwj qhov tshwm sim.

Hniav Hlau kos

Nws twb siv nyob rau hauv cov Nrab Hnub nyoog rau lub dai kom zoo ntawm riam phom thiab tej cuab yeej. Nyob rau hauv lawv kev zoo nkauj khoom uas feem ntau ua tsis tau zoo rau lub tsim yaam tshab ntawm txawj ob txhais tes ntawm Jewelers. Rau no hom ntawm cov hlau nto kev kho mob ntawm lub thib ob zoo tshaj plaws, uas yog, lub galvanic txoj kev. Qhov no txoj kev txhob tsim ntawm nkev kuab lom tog rau tib neeg uas tshwm sim thaum cov tshuaj kho mob, thiab yog npaum li cas zoo dua vim hais tias nws enables mus ua cov npoo dlaim phaj etched qauv.

Galvanic etching nyob rau hauv kev xyaum

Nyob rau hauv thiaj li yuav qhia lawv tej txuj ci thiab yuav pib txheej txheem no nyob rau hauv tsev, yog thawj zaug uas yog mus nrhiav qhov twg los ntawm DC voltage uas yog kwv yees li sib npaug zos rau 4-7 Volt. Zoo tagnrho - tsev neeg hwj chim mov nrog ib tug mus. Ces nws yog tsim nyog los tau ib tug tais ntawm ib tug insulating cov ntaub ntawv uas, uas yuav muab lub ntsha. Raws li cov tom kawg yuav tau siv ib tug nyeem tov ntawm ntau ntsev, tab sis feem ntau yog siv rau lub hom phiaj no yaj sulphate. Hlau yog siv rau hlau thiab hlau, thiab tooj liab - rau bronze, tooj dag thiab tooj liab. Cov hlau dawb paug yuav tsum tau degreased ua ntej. Rau lub hom phiaj no nws yog soldered tooj liab hlau tuav nws dipped rau 5 feeb mus rau hauv ib tug tov ntawm sodium hydroxide, preheated mus rau ib tug kub ntawm 50 ° C. Tom qab ntawd, preform yog pauv mus rau ib ob peb feeb rau ib cov kua nrog ib tug cov ntsiab lus ntawm 15% sulfuric acid, thiab ces kom huv si ntxuav nrog dej kub. Xeem npaj theem - qhov kev npaj ntawm mastic. Lub tin box mix suab, rosin thiab ciab nyob rau hauv ib tug kev faib ua feem ntawm 4: 2: 3 thiab yaj mus nrhiav tau ib tug homogeneous loj. Thaum nws tau txias, qhwv nws nyob rau hauv ib tug nyias daim ntaub thiab ib tug khoom tsav los ntawm me ntsis rhuab workpiece li ntev raws li nws yog them nrog ib tug uniform nyias txheej. Tom qab tag nrho cov no tau hardened, thov ib tug dej xim pleev xim rau yam qauv thiab txhuam putty riam qhov twg peb yuav tsum tau nyob rau hauv-tob. Tam sim no tso nws nyob rau hauv lub ntsha los ntawm plugging nyob rau hauv davhlau ya nyob twg rau qhov zoo ncej thiab cov hlau nrog lub Rho tawm kos npe rau ncua tej hlau kwv thiab kuj txo nws mus rau hauv lub ntsha. Thaum kawm tiav ntawm lub etching Unsolder hlau yaug tau Turpentine masterpiece thiab ua zaum kawg finishing (sib tsoo thiab polishing).
