Etching aluminiyamu panyumba

zotayidwa etching (zinthu za zitsulo izi) ikuchitika kuti kukonzamo padziko chapamwamba, kapena wosanjikiza zosafunika la dzimbiri. Ngakhale pali mitundu - luso pickling pamene zofunika kulembapo chitsanzo padziko mbali zitsulo.

mitundu ya etching

Etching zitsulo ambiri, ndipo zotayidwa makamaka, angakhale mitundu ikuluikulu iwiri: mankhwala ndi electroplating. The njira yamasika ikuchitika monga luso.

Mankhwala: mankhwala aikidwa mu chidebe amene poyamba anali anazitsanulira mwa njira ya acid amathiridwa kapena sulfuric. M'njira yomweyo anachita etching zotayidwa billet soda, eg ndi sodium hydroxide.

A galvanic (ayi - electrolytic kapena electrochemical) kumachitika chifukwa batire magetsi. Dongosololi yokha ikuchitika osamba wapadera, momwe muli ndi anode ndi cathode.

Kenako kuonedwa kuti aliyense wa njira zotayidwa etch mwatsatanetsatane. Komanso fufuzani njira yomwe ndi otetezeka kwambiri kunyumba.

Acid etching aluminiyamu

Chifukwa chakuti mu ndondomeko imeneyi ntchito asidi amphamvu kwambiri, ndi woyamba zofunika kutsatira kuchuluka tipewe ngozi pamene akugwira ntchito ndi iwo. The woyendetsa ayenera kuvala magolovesi, chigoba, thewera. Nkofunika kuti, chipinda cha alwendo njira yokha bwino mpweya wokwanira. Alibe maluso ena ndi popanda mankhwala ena ntchito ndi zidulo ali osavomerezeka.

Monga taonera, mankhwala aikidwa mu chidebe zotayidwa acid ndi. Nthawi zambiri zotayidwa ndi mankhwala asidi etching ntchito za reagents zotsatirazi: acid amathiridwa kapena sulfuric. Mwa kuchita nawo wa hydrogen adzamasulidwa zitsulo. Kunja, izo zikuwoneka motere: Mankhwala pamwamba ali ndi thovu laling'ono. Koma, mfundo imeneyi angathe kupewedwa powonjezera pasadakhale mphamvu zimathandiza wapadera. Choncho, zitsulo kutetezedwa ndi woonda filimu kuwira.

A mfundo yofunika kwambiri pa zonsezi pickling ntchito asidi anapanga zotayidwa ziyenela kuchitidwa mofulumira pamwamba zitsulo yokha anakhalabe zogwirizana.

The njira anafotokoza bwino mu muli matabwa kapena simenti. Pankhaniyi padziko mkati ayenera kuti alimbane ndi matailosi asidi zosagwira kuti kuwononga khoma chotengera.

Njira umagwiritsidwa ntchito kumapeto si sizachilendo.

Etching ya soda zotayidwa

Nthawi zambiri, pamene njira imeneyi ntchito njira amadzimadzi hydroxide ndi sodium (optionally kapena popanda zina).

Ndipo ntchito kuyeretsa padziko mankhwala zotayidwa kapena zosafunika okusayidi lubricant ndi kupeza see (glossy kapena matte) pamwamba.

N'chifukwa chiyani muyenera kotero bwinobwino kutsukidwa? Kwa chotsirizidwa (mwachitsanzo, kukongoletsa mapulani zinthu, mipukutuyi) anali pamwamba wangwiro. Ndiponso, njira imeneyi ntchito gravure chosema.

Njira soda etching zotayidwa pa dzanja limodzi, ndi mokwanira otsika, koma ndi nthawi yambiri.

Features njira

njira zona ali ku anayi peresenti khumi hydroxide lapansi. Kutentha mu etching ndi soda ndi za 40-90 madigiri Celsius.

Ngati ndi kotheka, kuti kuunika thovu ❖ kuyanika pa workpiece ndi ntchito moisturizer kapena enaake apadera.

Kutentha pafupifupi pakati pa ndondomeko - ndi madigirii sikisite. Zinali pansi pa ntchito matenthedwe ndi Mkhalidwe pamwamba kuyeretsa.

zokhazikitsidwa mulingo woyenera zotayidwa chiyero - 99,5%, ndipo anthu ambiri ndi sodium hydroxide njira - 10, 15, kapena 20%.

Choncho, pa zimene zotayidwa kusungunuka hydroxide ndi sodium, wa hydrogen limasuka. Chifukwa ndi gulu aluminate, ndipo kokha alipo mu njira soda.

njira Komanso zikuchitika mu etching ndi soda

Pa ndondomekoyi, kuchuluka kwa hydroxide ndi sodium pang'onopang'ono ang'onoang'ono. Ndipo chotero amachepetsa ndi otaya liwiro kwa ndondomekoyi, koma kumawonjezera kukhuthala.

Malinga thanki si kuwonjezera hydroxide sodium, zimene akhoza kukhala wochedwa. Koma pamapeto, kapena brownish bwino njira yothetsera etching zotayidwa limakhala loyera.

Ndipo kuyambira kuti ndondomeko liwiro ndi kuchuluka.

Anachita ndi woterowu aluminiyamu hydrate, zomwe zikuwoneka ngati slurry a. Ndi allocated hydroxide sodium, amenenso zofunika etch ndondomeko anapitiriza.

Zotsatira pa njira ankaona

Experimentally zalembedwa kuti ndi sodium hydroxide njira pansi wolimba tanthauzo lake mu ndondomeko etching akuyamba "kuyamwa" zotayidwa. Ndipo izo zimachitika malinga ndi kuchuluka kwa koloko caustic yafupika wachinayi buku pachiyambi. Ndipo pambuyo kuti ndondomeko adzapitiriza ufulu caustic koloko, silifuna chiwerengero chawo. Zimenezi zimadalira kutentha, mwamphamvu ndi pafupipafupi ntchito ya oyima (Kuimaima).

Pankhaniyi, hydrate Falls pang'onopang'ono precipitate yosiyanasiyana timibulu pansi ndi / kapena mbali za chidebe. The hydrate chotsatira ndi mokwanira wandiweyani ndipo kudzakhala kovuta kuchotsa. Nthawi zina ndi kuyesetsa kuthetsa mwachindunji padziko coils magetsi.

Pali mfundo ina yofunika limene limafotokoza kuti zili zotayidwa. Pa etching katundu zitsulo ndi sodium hydroxide imeneyi iyenera adatsata ndi chiŵerengero cha hydroxide zotayidwa. Chifukwa chakuti a zotayidwa, kotero ndondomeko adzakhala pang'onopang'ono. Zopindulitsa zikuonekeratu kuti m'pofunika zonse kuwonjezera kuchuluka kwa hydroxide ndi sodium monga kuchuluka kwa zotayidwa mu chotengeracho.

Choncho, zotayidwa soda etching ndondomeko akhoza anapitiriza kalekale. imfa ya koloko caustic kudzachitika pokhapo chifukwa cha phulusa ndi nthunzi.

Njira imeneyi kwenikweni ntchito zopindulitsa. Koma pali ena mokoma, imene muyenera Musaiwale kuti nthawi kuchotsa anaumitsa chitayiko hydrate; kuyeretsa sefa; kumbukirani kuti chidebe imene ndondomeko pa zonse ntchito zingatithandize osaposa zaka ziwiri.

Enawo, zosokonezeka aliyense pa ntchito njira imeneyi si chawululidwa.

Total pambuyo mankhwala etching wa zotayidwa workpiece pamwamba m'pofunika bwinobwino nadzatsuka ndi n'chongoletsa kuwalitsa ntchito 15-20% mphamvu asidi nitric njira. Zimenezi amatchedwa pickling.

njira electroplating

Njira ya chiwiri ya etching - galvanic. Ndi yosavuta ndi nthawi zambiri mofulumira. Ndi chifukwa mkulu kwambiri khalidwe padziko mankhwala, ndondomeko yonse ya chithunzi (pa njira Art monga plating mitundu).

Mbali ya njira iyi kuti akugwiritsa ntchito mphamvu zamagetsi (4-5 B).

Inunso muyenera kusamba kukula izi, kotero kuti zimagwirizana ndi mankhwala a zotayidwa. Chuma yomanga mphika, kuti akhale insulator. Zikuchokera etching kusamba kwa zotayidwa - njira ya sulphate mkuwa ndi sodium kolorayidi.

Asanayambe ndondomeko preform ayenera kutsukidwa ndi degreased. Kenako, solder malata mkuwa waya kuti mankhwala ndi kuchepetsa izo sodium hydroxide njira, ndiyeno - mu sulfuric asidi njira. Patapita mphindi 2 ndi rinsed lolamulidwa yotentha madzi kutuluka. Ankaletsa pa mfundo iyi kukhudza mankhwala.

Ngati mbali zina za udzu workpiece Sikuti iwo kutsatira utomoni wonunkhira. Ndiye inu mukhoza kuyamba ndondomeko.

Njira imeneyi imagwira ntchito awiri otchedwa zogwiriziza, zimene ziyenera Ufumuyo kwa anode (kuyang'anira zabwino) ndipo cathode (zoipa) mphamvu zoyendetsera. Nkofunika kuti zogwiriziza izi anaiika kudutsa kusamba. Thandizo ndi yomatidwa ndi anode wa preform ku zotayidwa, ndipo chachiwiri - billet wa zitsulo zosiyana.

Zonsezi igwera mu kusamba ndipo anakhalabe wina kuchuluka kwa nthawi. Kenako osambitsidwa ndi turpentine ndi doobrabatyvaetsya umapezeka ndi kupukuta.

art etching

Mtundu wa njira plating chotchuka kwambiri masiku ano. Ndi izo, inu mukhoza kuchita zojambula kukopera, zojambula mochita kugoba, luso zipsera, zokongoletsera iliyonse workpiece wa zitsulo.

Ndipo zotsatira zake zimakhala bwino kwambiri, chithunzi chokongola. Ndiko kunena kuti, ntchito za mlembi, chimene chikanakhoza kusiya nokha kapena ndalama.

ndi chithunzi chenicheni yokha, mudziŵa nokha kusindikiza kapena (ntchito laser chosindikizira) pa pepala. Kenako, padziko ndi zomatira tepi sticked pepala ndi muzimutsuka ndi madzi otentha. Potsatira zotsatira za chithunzi ukhalebe pa zomatira tepi. Siyani kuti ziume. Nthawiyi, kufunika kukonzekera pamwamba zitsulo kumene chitsanzo umagwiritsidwa - degrease mowa wake.

Ndiye kumata ndi kum'mamatira filimu unatengera padziko workpiece, motero kumasuka izo kwa thovu mpweya. Yolimidwa otentha choboolera owonjezera zomatira ndi onse zosafunika, kupatula wachithunzi yokha.

Etching ikuchitika m'njira yomwe kale tafotokozazi - yokutidwa.

Dziwani: pamene ndondomeko iyi ayenera kumasula mpweya zoipa, choncho anthu bwino kutuluka mchipindamo.

Choncho, zotayidwa etch kunyumba ndi zotheka. Ingokhalani otsimikiza muyenera kuchita mosamala zonse zofunika chitetezo!
