Goge aluminum da hannuwansu: yadda, kayayyakin aiki, da na'urorin

Aluminum ne mai gwada m karfe. Duk wani samfurin daga shi ƙarshe hasarar da asali tsari, a kan surface bayyana sawa, da oxides, da samfurin fades. Idan kana son ka ba da haihuwa abubuwa wani sabon nau'in, shi ya kamata goge aluminum. Don yin wannan, daya daga cikin wadannan hanyoyin da za a iya amfani da:

• electropolishing.
• sinadaran polishing.
• ado etching.

aluminum polishing hanyoyin: sinadaran Hanyar

Wannan fasaha ne tsabtace muhalli, sauki da kuma sauri fairly. Yana yiwuwa a gane, da acid-resistant karfe, wanda zai samar da tushen da polishing wanka. Idan girma na aikin shi ne gwada da kananan, yana yiwuwa su yi amfani da crucibles sanya na ain. A ganga mai cike da acid bayani:

• sulfuric.
• nitric.
• Phosphoric.

Products an saukar a cikin zafi bayani, da yawan zafin jiki ya kamata Range daga 90 zuwa 120 ° C, da karshe darajar zai dogara ne a kan maki na aluminum. Fallasa aluminum abun da ke ciki dole ne a cikin dakika 30 ko minti, maimaita mataki zuwa game da 6 sau. A tsakanin wanku, kuma da bukatar a kullum girgiza.

chemically goge aluminum ne mafi alhẽri a lokacin da amfani da wani drum juyawa gudu. Bayan kammala wannan jan a kan surface zai tuntube da jan tsare. Ya kamata a cire ta rinsing karkashin ruwan famfo tare da wani low zazzabi. Wannan ya kamata a yi a tarko. A na gaba mataki na samfurin sarrafa kashi 30 cikin dari nitric acid.

Ƙarin shawarwari a kan ayyukan

Aluminum polishing iya cika da alkaline mafita:

• trisodium phosphate.
• sodium nitrate.
• caustic soda.
• sodium nitrate.

Su zafin jiki dole ne mafi girma kamar yadda idan aka kwatanta da acidic hanya, da iyaka ne 120-140 ° C. Products dole tsayayya game 5-20 seconds. Lokacin da wannan dabara da ake amfani, da asarar zai zama daidai da aluminum na game 8 microns jimlar Layer kauri.

A amfani da electro-

Aluminum polishing iya yi a wata hanya dabam. Kamar wancan shi ne mai yiwuwa a samu m, kuma m surface, da tsabtace shi ne na high quality. Wutan ga irin ayyukan a mafi yawan lokuta mallaka sulfuric da phosphoric acid, da sauran aka gyara zasu dogara a kan abu.

Wutan iya cimma sheki bayan kammala. Domin aiwatar da zazzabi ya zama m fiye a cikin sama hali, da zazzabi da iyaka ne daidai da 60 zuwa 90 ° C.

Polishing dole ne a za'ayi domin minti 5, yayin da yanzu yawa na iya zama daidai da 10-50 A / dm². Tsari ga polishing cathodes shafi yin amfani da gubar, amma akwai sauran gami da samar da ga yin amfani da bakin karfe. Polishing bukatar yin amfani da duralumin dakatar, kazalika da electrolyte wanka da polyethylene, gubar ko ptfe aiki. Kana bukatar ka shirya wani alkaline electrolyte, su ne maras tsada.

A kan aiwatar da sigogi zai shafi abun da ke ciki na electrolyte, zazzabi iyaka iya bambanta daga 40 zuwa 95 ° C game da daukan hotuna, shi yana daga 3 zuwa 6 da minti, alhãli kuwa da halin yanzu yawa a anode ne mai iyaka na 3-20 A / dm². Zabar cathodes, nickel ne da za a fĩfĩta.

Features ado etching

aluminum polishing Hanyar iya zama ado. Wannan dabara hidima a matsayin subspecies na electropolishing. Aluminum gami suna etched da anodes gwamnatin phosphorus-chromium electrolyte. A surface na articles kafa crystalline juna wanda yana da nau'i na kwasfa ko sanyi. A cikin anode sanda rataya fita duk cikakkun bayanai, sa'an nan kuma ba za ka iya fara magani. Jān kafar da ya kamata a da za'ayi a wani irin ƙarfin lantarki na 25-30 V. By karshen irin ƙarfin lantarki yakan har zuwa 35-40 V, da anodic halin yanzu yawa ne daidaita da iyaka na 8-12 A / dm², yayin da yawan zafin jiki zai bambanta daga 50 zuwa 80 ° C.

Aƙalla 20 minutes daga baya bayyananne zane. Idan irin ƙarfin lantarki za su fara tashi kyauta, za mu iya ɗauka cewa tsari ne cikakke. Bayan karshen magudi kayayyakin an wanke, da bushe, shi ne da za'ayi anodizing kan su. Aluminum aka sa'an nan ya rasu kwayoyin Paint.

Fuskance aluminum za a iya samu ta hanyar wani Hanyar luster da anodic etching, da ake kira iskritom. Don wannan samfurin kafin da kuma bayan aiwatar ne hõre zafi magani a wani musamman makirci. Za ka iya amfani da anodic etching "Snowball", wanda ba ka damar haifar da wani Matte surface kyalkyali.

Abin da wata hanya mafi amfani a gida

A manna ga polishing ne daya daga cikin mafi yawan amfani da kayan aikin a cikin gida ga polishing aluminum. Wannan shi ne saboda gaskiyar cewa sinadaran qagaggun na daban-daban virulence, su ne m ga lafiyar dan adam. Polishing za a iya amfani da:

• sandpaper.
• scrubbing goge;
• lacquer.
• Rags.
• tsaftacewa kayayyakin ga irin barasa.

A lokacin da zabar sandpaper da muhimmanci kada su overdo shi tare da hatsi, domin in ba haka ba zai yi janye scratches. Don inganta lalacewa juriya da kuma wani mai sheki lacquer ne mafi alhẽri ga amfani.

Features na electrochemical polishing

Electrochemical polishing na aluminum samar domin aiwatar da layi daya aiki da kuma sinadaran lantarki da tasirinsa. Bisa ga fasahar da irin wannan hanyar da hidima a matsayin wani ɓangare na anode lantarki, shi an haɗa zuwa tabbatacce DC wadata Madogararsa. Workpiece tare da bari saukar halin yanzu a cikinta dole ne a nutsa cikin wani tafki wanda aka cika da electrolyte. Da muhimmancin da biyu lantarki fallasa jan cathodes.

Amfani da wani polishing inji

Machine ga polishing ne m wajen goya da aluminum na asali mai sheki. Za ka iya amfani da buff a 1000, wanda aka moistened da ruwa. Soso ko zane dole ne a yi amfani da sarrafa ruwa rabo. Bugu da ari hada polishing inji 1400 juyin minti daya. Lokacin da irin wannan SPRAY rate zai warwatsa a kusa da 1 m.

aluminum surface zai zama mai tsanani, ruwa zai ƙafe. Ka dole ne a shirya domin gaskiyar cewa cikin da'irar za a hammered aluminum "porridge". Saboda haka, kowane minti daya na inji ya kamata a tsaya ga kurkura nika dabaran da rigar soso a karkashin ruwan famfo. Don wannan karshen, wasu sana'a amfani na al'ada bryzgalku.

"Porridge" kamata a tsabtace ko da tare da cikakken bayani. Luster fita, idan za ku bugu da žari amfani kuma ji. Wannan mataki shi ne daya daga cikin mafi muhimmanci. Yana zai dogara ne daga gare ta 80% na karshe sakamakon. Ji ya mika 10 mm bayan da tushe da'irar kamata a moistened, watering ya bryzgalku. Daki-daki ne moistened tare da wani damp soso. A manna ake amfani da su Yaren mutanen Poland da m, da aikace-aikace kamata a da za'ayi a kan workpiece, maimakon a da'irar.

ƙarshe

aluminum goge da hannunsa na iya zama da dama wajen, amma daya daga cikin mafi inganci shi ne mai manna. Yana ba ya dauke da ammonia Additives kuma iya m tsaftace abu daga scratches da roughness. Tare da wannan tsarin shi ne zai yiwu a cimma asali luster. A m Layer zai ware oxidations bayyanar na dogon lokaci.
