Etching metal pamba. Nzira yekushandisa mifananidzo kune hardware: nhanho-nhanho mirairo

Mucherechedzo uye dzimwe nguva zvinotsiva kukanda uye kuveraving, zvinogadzirisa hurongwa hwose huri nyore. Iwe unogona kuwana mifananidzo se concave - zororo, kana kuti convex-bas-relief. Mucheka uye mishonga kumba kunogona kuva chemakemikari uye galvanic. Nzira yekutanga inonyanya kuora kana inoshandiswa pamba, saka kutanga tichashandisa yechipiri, inonziwo electrochemical.

Zvishandiso

Zvinotora kutora simba kana shanduko inogona kutora kubva ku4 kusvika ku7 V. Mukuwedzera, unoda bhati dielectric, inofanira kunge ine chikamu chakakosha uye chinhu chechipiri chesimbi chakabatanidzwa kune anode.

Kuti uratidze chimiro chesimbi, zvakakosha kushandisa sero re electrolyte resimbi sulfate. Kana mufananidzo uchidikanwa pamhangura kana mumhangura, ipapo sarphate inoshandiswa. Iwe unogonawo kushandisa sirori chloride. Chinhu chikuru ndechokuti mvura yakasvibiswa.

Kugadzirira chikamu chekuita

Kuchengeta kwaiva yunifomu uye munzvimbo dzakarurama, chikamu chinoda kucheneswa tsvina, uye chikawedzera. Kuti uwane basa rakanaka, tambo yemhangura inotengeswa kune rumwe rutivi paatini, nokuti ichava yakakodzera kubata chinhu chacho. Kuti uchenese nzvimbo, inofanirwa kuderedza chinhu chakashandurwa kuva 10% sodium hydroxide, inotonhora iyo iri 50 ° C, uye mu 15% sulfuric acid solution uye inobata ipapo ipapo kwemaminitsi maviri, uye oshambidza nemvura inopisa. Kana iyo nzira yapera, nzvimbo yechinhu ichi ichacheneswa zvakakwana, uye zvechokwadi, haugoni kuvabata nemaoko ako.

Electrochemical etching yesimbi

Tinofanira kuchengetedza nzvimbo dzisingafaniri kugadzirwa. Kuti uite izvi, shandisa mastic chaiyo pane idzi nzvimbo dzepamusoro. Inogadzirwa kubva kumativi matatu emakisi uye maviri-rosins, anonyorerwa mumata, anogona. Mushure mokunge zvinhu zvose zvinoshanduka kuva mashoma akaenzana, zvinobvumidzwa kunononoka pasi uye kupatsanurana kuita zvidimbu. Mumwe nomumwe wavo akaiswa mujecha, kuitira kuti gare gare, kana achinyunyisa, seastics akawanda sezvaanoda anogona kupinda mukati maro. Mushure meizvozvo, basa rekushanda, iro ratinozoita, rinopisa. Iye zvino tora musanganiswa wakasikwa, wakaiswa mu cheesecloth, uye senya pasi neyunifomu yakasara.

Pashure pokunonoka, mastic inosimba. Kubva kumusoro iyo yakafukidzwa nepeji inopenya-yakasvibiswa. Inogona kuva mvuracolor kana gouache chena. Mushure mezvo kupfeka kunofanira kuoma. Ipapo iwe unogona kushandisa mufananidzo, pane pende iyo ichabata zvakanaka. Inogona kuenzanisirwa nepenzura kana kutumidzwa kuburikidza nepa carbon paper. Zvadaro mhirizhonga iyi inofanira kuve yakanyungudutswa neine tsanga kune iyo tsvina pachayo.

Iye zvino kubata kwesimbi ne electrolysis kunotanga, tinobatanidza bhari rimwe kune anode - pamwe, imwe kune cathode - kuderedza. Kune wekutanga tinobatanidza tsanangudzo iyo iyo mufananidzo ichashandiswa, kune yechipiri chero mapepa akaumbwa nesimbi. Mushure meizvi, kushandiswa kwekugadzira simbi kunotanga apo chifananidzo chacho chakanga chakatemwa.

Kana iwe uchida kugadzira mifananidzo yakawanda, zvose zvinoitwa nenzira imwecheteyo sezvatsanangurwa pamusoro apa. Chengetani chete dzinoongororwa nguva dzose, uye kana zviduku zvacho zvichisimudzirwa kune zvakadzika zvakadzama, chikamu chacho chinobviswa uye chinorongedzwa nemhepo inopisa mastic nebhurashi. Kana iyo yakaoma, zvose zvinodzokororwa zvakare kune imwe yero yechifananidzo. Pakugadzirisa, mufananidzo unogadzirwa zvishoma nezvishoma.

Nenzira iyi, simbi inoiswa mumusha, mushure mezvo iyo inoshambidzwa ne turpentine, uye iyo inoputika, ichipa chigadzirwa chizere.

Chemic etching

Iye zvino funga kuti ungagadzira sei mufananidzo pamusoro pesimbi kusina kushandisa magetsi. Kuti tiite izvi, tinoda makemikari ayo anotengeswa zvakasununguka mune zvigadzirwa zvema Hardware. Saka, ngatitange. Nokuti etching tichatoda:

• White Spirit;
• Pende isina kupera mu White Spirit;
• Acetone;
• Resin, iyo inoshandiswa kuvhara matenga;
• Kazhinji munyu;
• Vitriol yemhangura.

Kuchenesa chikamu

Kutanga, tsanangudzo iyo iyo chigadziro chagadzirirwa inotariswa nechepasiti sandpaper uye inopera. Kana nzvimbo yakagadzirira, unoda nzvimbo iyo iyo ichashandiswa, yakasungirirwa nematepi ekunamatira kana chimwe chinhu chakadai. Mushure meizvozvo, zvese zvepanyika, apo makemikari etching haafaniri kuchinja simbi, kupora pamusoro pepende. Inogona kuva chero ruvara, chinhu chikuru ndechokudzivisa kuMweya Mutsvene.

Apo pepa inomesa, unogona kubvisa tape yekunamatira. Pasi payo, simbi yakachena, yakagadzirira kuumba mufananidzo pairi. Iye zvino pane iyi "mini-ngoro" unoda kuisa mufananidzo. Iyo yakaitwa ne resin, iyo inopedzwa mu White Spirit, kusvikira yava yakaoma, sepende. Anoshandisa brashi kuti atange mufananidzo unoda. Chinhu chakanaka pamusoro pepende yakagadziridzwa ndeyokuti kana chimwe chinhu chisiri kushanda mukudhirowa, unogona kuchibvisa nekudhinda machira kana swaton coton mu White Spirit. Kana pane zvikamu zviduku zvakanyanya mumufananidzo izvo zvisina kusimbiswa nebhashira, zvinogona kugadziriswa neine tsono, kubvisa pane zvakanyanya mushure mekuoma.

Nenzira iyi, zvinokwanisika kuvhara banga, makii, mune rusange, chero chinhu chesimbi. Iye zvino, kana mufananidzo wacho wakagadzikana zvachose, unogona kuenderera mberi ku-etching pachako.

Etching solution

Tinoda litre yemvura umo inoparadza 100 g yemhangura sulfate, uye mushure mekuwedzera munyu. Inofanira kudururwa kusvikira yarega kuparara. Musanganiswa unoguma uchava nemuvara webhuruu. Zvisinei, mushure mekunge chinhu chesimbi chakanyudzwa mukati maro, ruvara ruchazotanga kuchinja.

Saka, tinosunura chikamu. Icho chemakemikari inotanga pakarepo. Muzvinhu izvi zvose zvinogadzirwa, hapana zvinhu zvinokuvadza zvinosunungurwa, saka simbi yakadaro yesimbi uye yakachengeteka iri yakachengeteka.

Zviito panguva yemakemikari anoita

Munguva yekuita, danda rinoumbwa, iro richava rakawanda. Iyo inhibisa mushonga wose, saka iwe unofanirwa kuigadzira nguva nenguva nemvura. Usaita izvi nerubatsiro rwezvipfeko zvakasiyana-siyana, mabhurusi nemamwe mathuluzi, nokuti unogona kukuvadza pende. Asi zvinoratidzika kuti zvakabata mufananidzo wose, uye zvichave zvichinyomba kana, kana uchiita kubata kwemuti, somuenzaniso, uchikwevera pairi, iwe unoriparadza nenzira isingaiti. Iri ibasa rakaoma, rinoda ruoko rwakasimba uye kushivirira.

Kubva panguva iyo metal inoramba ichigadzirisa muhuturo, zvakadzika zvemufananidzo zvinotarisana zvakananga. Nzira chaiyo isiripo, saka, tenzi mumwe nomumwe anofanira kuzviona iyeyo yemakemikari anoita. Uye kana mushure mokuita izvi kakawanda, zvinenge zvichikwanisika kutaura nechivimbo nguva ipi inofanirwa kuti kuratidzwa kwemuitiro unoda kuve wakagadziridzwa zvakadzika.

Kubatsira uye kusagadzikana kwe electrochemical and chemical etching

Kunobatsira kwe electrochemical etching yesimbi mudzimba ndechokuti nzira yakasikwa yakanyatsojeka, izvi zvinonyatsoonekwa kana iwe uchichitarisa nechiwedzera. Zvisinei, kusagadzikana ndechokuti nzira iyi inoda kuvepo kwechigadzirwa chemagetsi, chisingasviki kune munhu wose.

Zvakanakira zvemakemikari etching zvinosanganisira chokwadi chokuti zvinhu zvose zvaunoda zvinogona kutengwa pachitoro che hardware. Izvi zvinoshandiswa zvishoma uye, zvinonyanya kukosha, haufaniri kutarisa pane imwe nzvimbo yekubatsira magetsi kana mamwe mazvigoni anokwanisa kupa 4 kusvika ku7 V. Zvisinei, mhedziso isina kukwana yemufananidzo haigoni.
