Etching hlau nyob hauv tsev. Yuav ua li cas thiaj li siv cov duab rau khoom kho mob: cov lus qhia ua raws kauj ruam

Hlau etching tej zaum kuj hloov qhov casting thiab engraving, nws ua tus txheej txheem tseem ntau yooj yim. Koj tuaj yeem tau txais ib daim duab uas yog concave - nyem, los yog convex - bas-relief. Hlau etching tom tsev yuav ua tau tshuaj lom neeg thiab khes qaub. Cov kev xaiv thawj zaug yog ntau yam tshuaj lom thaum siv hauv tsev, yog li ua ntej peb yuav siv ob, nws tseem hu ua electrochemical.

Khoom siv

Nws yog ib qho tsim nyog yuav tsum tau siv lub hwj chim los yog lub tshuab hluav taws xob uas yuav xa tau los ntawm 4 mus rau 7 V. Ntxiv mus, koj xav tau ib da dej dielectric, nws yuav tsum muaj qhov tsim nyog thiab ob qho khoom siv hlau txuas nrog anode.

Yuav kom ua tau etching rau cov hlau txawv, yuav tsum tau siv raws li lub ntsha tov ntawm ferrous sulfate. Yog hais tias tus qauv yuav tsum tau rau ntawm qhov chaw ntawm tooj liab los yog tooj dag, cov kev siv ntawm tooj liab sulphate. Koj kuj siv tau ferric chloride. Qhov loj tshaj plaws yog hais tias cov dej yog distilled.

Npaj ib sab rau kev cuam tshuam

Rau etch yog uniform thiab nyob rau hauv txoj cai qhov chaw, qhov yuav tsum tau ntxuav ntawm cov av, thiab tseem degreased. Kev ua haujlwm yooj yim dua, ib txoj hlua tooj liab yog siv rau ib feem ntawm tin, vim nws yuav yooj yim los tuav qhov khoom. Los ntxuav qhov chaw, nws yog qhov yuav tsum tau txo cov khoom kom hloov mus rau hauv 10% sodium hydroxide, qhov kub ntawm 50 ° C, tom qab ntawd 15% sulfuric acid kua thiab tuav nws rau ob feeb, ces yaug nrog dej kub. Thaum txoj kev ua tiav lawm, cov qhov ntawm qhov khoom yuav raug muab ntxuav tag nrho, thiab tau kawg, koj kov tsis tau lawv nrog koj ob txhais tes.

Electrochemical etching ntawm hlau

Peb yuav tsum tau tiv thaiv cov chaw uas yuav tsum tsis txhob cuam tshuam. Ua li no, siv cov mastic tshwj xeeb rau cov cheeb tsam ntawm qhov chaw. Nws yog tsim los ntawm peb qhov chaw ntawm siv quav ciab thiab ob - rosins, lawv melted nyob rau hauv ib tug tin muaj peev xwm, stirring. Tom qab txhua yam pauv mus ua homogeneous pawg, nws raug tso cai cia txias thiab phua ua voos. Txhua ntawm lawv yog muab tso rau hauv qhov ncauj, yog li ntawd tom qab, thaum nias, ntau cov mastics raws li xav tau nkag mus los ntawm nws. Tom qab ntawd, lub workpiece, uas peb yuav etch, heats li. Tam sim no noj cov sib tov sib xyaw, uas tau muab tso rau hauv cheesecloth, thiab rub tus nto nrog ib txheej txheej.

Tom qab txias, tus mastic ua ruaj khov. Los ntawm saum toj no nws yog them nrog ib lub teeb dej-soluble xim. Nws tuaj yeem muaj dej los yog dej dawb. Tom qab hais tias lub txheej yuav tsum qhuav. Tom qab ntawd koj tuaj yeem thov daim duab, ntawm cov xim nws yuav zoo. Nws tuaj yeem pom muaj ib daim cwj mem los yog pauv ntawm daim ntawv. Tom qab ntawd qhov no contour yuav tsum tau kos nrog ib rab koob rau cov hlau nws tus kheej.

Tam sim no lub etching ntawm hlau los ntawm electrolysis pib, peb txuas ib bar rau lub anode - ntxiv, qhov lwm mus rau cathode - rho tawm. Mus rau thawj peb txuas qhov kev nthuav dav uas cov duab yuav tsum muaj ntaub ntawv, rau qhov thib ob ib qho phaj los ntawm cov hlau. Tom qab qhov no, cov txheej txheem ntawm etching lub hlau pib pib qhov twg cov duab raug scratched.

Yog tias koj xav tsim ib qho teeb duab multilevel, txhua yam yog ua raws li tib txoj kev raws li piav saum toj no. Tsuas yog cov txheeb xyuas txhua txhua lub sijhawm, thiab thaum twg qhov tsawg tshaj plaws ntawm lawv yog etched mus rau qhov tob uas yuav tsum tau, feem ntau yog muab tshem tawm thiab pleev xim rau nrog ib lub rhaub khib nrog ib txhuam. Thaum nws txhaws, txhua yam yog rov ua dua rau qib tom ntej ntawm daim duab. Nyob rau hauv txoj kev, ib qho duab pib maj.

Nyob rau hauv no txoj kev, hlau etching yog nqa tawm nyob rau tom tsev, tom qab uas lub saum npoo yog ntxuav nrog turpentine, thiab ces polished, muab cov khoom ua kom tiav zoo.

Tshuaj lom neeg etching

Tam sim no xav tau li cas los tsim ib daim duab ntawm ib lub qhov hlau tsis siv cov khoom siv hluav taws xob. Ua li no, peb xav tau cov tshuaj uas muaj muag nyob rau hauv cov khw muag khoom kho mob. Yog li, cia peb pib. Rau qhov etching peb yuav tsum tau:

• Ntsuj Plig Dawb Huv;
• Ib cov xim tsis thim rau hauv Ntsuj Plig Dawb Huv;
• Acetone;
• Resin, uas yog siv los npog ru tsev;
• Cov ntsev ntau;
• Copper vitriol.

Tu ib sab

Yuav pib nrog, qhov kev nthuav dav uas qhov duab tau npaj tseg yog muab xau tawm nrog cov nplua thiab zoo dua. Thaum cov nplais npaj txhij, koj xav tau ib qhov chaw uas cov qauv yuav siv, ua zoo nrog nplaum nplaum los sis ib yam zoo li ntawd. Tom qab ntawd, tus so ntawm qhov chaw, qhov twg cov tshuaj lom neeg yuav tsum tsis txhob cuam tshuam cov hlau, pleev xim rau xim. Nws tuaj yeem ua tau xim, qhov tseem ceeb tshaj plaws yog los ua kom tus Ntsuj Plig dawb.

Thaum twg cov xim nrig, koj tuaj yeem tshem tawm cov ntaub nplaum nplaum. Nyob rau hauv nws, ntshiab hlau, npaj txhij los tsim ib daim duab rau nws. Tam sim no ntawm no "mini-canvas" koj yuav tsum tso duab. Nws yog tsim nrog reinc, uas yog yaj hauv Neeg Ntsuj Plig, kom txog thaum nws ua kua, xws li xim. Nws siv txhuam txhawm rau kos duab. Dab tsi yog qhov zoo ntawm cov xim zoo li no yog tias yog tias tsis muaj dab tsi tsis ua hauj lwm hauv daim duab, koj tuaj yeem tshem nws los ntawm daim ntaub los yog paj rwb hauv Plig Dawb Huv. Yog tias muaj cov ntsiab lus me me heev hauv daim duab uas tsis tsim los ntawm txhuam, lawv tuaj yeem kho nrog ib rab koob, khawb tawm ntau heev tom qab so qhuav.

Nyob rau hauv no txoj kev, nws yog ib qhov ua tau kom etch lub riam, yawm sij, feem ntau, tej yam khoom siv hlau. Tam sim no, thaum lub teeb duab tiav lawm, koj tuaj yeem mus rau qhov kev cuam tshuam nws tus kheej.

Kev daws teeb meem

Peb xav tau ib liter dej nyob rau hauv uas dissolve 100 g ntawm tooj liab sulfate, thiab tom qab ntxiv ntsev. Nws yuav tsum tau poured kom txog thaum nws ceases yaj. Lub resulting cov dej yuav muaj xim xiav. Txawm li cas los, tom qab cov khoom siv hlau ntim rau hauv nws, lub xim yuav pib hloov mus rau ntsuab.

Yog li, peb hle lub tsho. Cov txheej txheem tshuaj pib tshwm sim tam sim ntawd. Hauv txhua qhov no, tsis muaj teeb meem cov khoom raug tso tawm, yog li cov hluav taws hauv qhov hluav taws xob hauv tsev tsis muaj teeb meem.

Kev ua thaum lub caij tshuaj lom neeg

Thaum lub sij hawm cov tshuaj tiv thaiv, ib cov quav hniav yog tsim, uas yuav dhau los ua ntau dua. Nws inhibits tag nrho txoj kev, yog li koj yuav tsum tau periodically ntxuav nws tawm nrog dej. Tsis txhob ua li no nrog kev pab los ntawm ntau yam txhuam, txhuam thiab lwm yam cuab yeej, vim hais tias koj tuaj yeem ua kom puas rau xim. Tab sis nws zoo nkaus li tuav tag nrho cov duab, thiab nws yuav thuam yog tias, thaum nqa tawm ntawm rab riam, piv txwv, kos duab rau ntawm nws, koj tsis zoo rau nws. Qhov no yog ib txoj hauj lwm zoo heev, xav tau ib sab tes thiab ua siab ntev.

Txij lub sij hawm thaum lub sij hawm uas cov hlau yuav nyob hauv kev daws, qhov tob ntawm tus qauv nyob ncaj qha. Tsis muaj cov txheej xwm tsis muaj nyob, yog li ntawd, txhua tus ascas yuav tsum tau saib xyuas nws cov tshuaj tiv thaiv. Thiab tsuas yog tom qab ua qhov no ob peb zaug, nws yuav hais tau tseeb nrog lub sij hawm twg yog qhov tsim nyog rau kev tshwm sim ntawm qhov kev xav tau ua ntej yuav xeeb tub.

Qhov zoo thiab qhov tsis zoo ntawm electrochemical thiab chemical etching

Rau qhov zoo ntawm electrochemical etching ntawm hlau nyob hauv tsev yog tias tsim qauv ntau dua, qhov no yog pom meej yog tias koj saib nws nrog kev nce. Txawm li cas los xij, qhov tsis zoo yog tias qhov no yuav tsum muaj qhov hluav taws xob, uas yuav tsis yog rau txhua tus.

Qhov zoo ntawm cov tshuaj lom etching muaj qhov tseeb tias txhua yam koj xav tau yuav yuav tom khw kho vajtse. Cov khoom xyaw no pheej yig thiab, qhov tseem ceeb dua, koj tsis tas yuav nrhiav qhov chaw rau lub hwj huam los yog lwm cov khoom siv tawm ntawm 4 mus rau 7 V. Txawm li cas los xij, cov duab tsis zoo ntawm daim duab yog rho tawm.
