Polishing anodized tsari

Polishing anodized shi ne don electrolyze da conductive acidic electrolyte ta halin yanzu, don haka kamar yadda anodize da aluminum karfe surface hada da anode, da kuma ta halitta girma a lokacin farin ciki da kuma m alumina m fim a kan aluminum surface. Wannan fim ɗin oxide ba ƙari ba ne kuma ba zai kwaɓe ba. Fim ɗin oxide mai haske ne kuma marar launi, kuma tsarin microcrystalline shine saƙar zuma hexagonal. Ba zai iya amfani da launi na halitta na aluminum kawai don haskaka ƙarfin ƙarfe mai ƙarfi ba, har ma da launi daidai a cikin micropores don ba wa bangon labule kyakkyawan launi, wanda ke faɗaɗa filin aikace-aikacen hangen nesa.

Ayyuka:

Ƙwararren aluminum oxide na anodized tare da daidaitaccen fim ɗin oxide mai kauri (3um) ba zai canza launi ba, lalata, anodize ko tsatsa na dogon lokaci. Za a iya amfani da murfin alumina na anodized tare da fim mai kauri (10um) a waje kuma ana iya fallasa shi zuwa rana na dogon lokaci ba tare da canza launi ba.

sifa:

Bayanin bayanin martabar alumini mai launi mai launi na Tri acid shine mahimman bayanan aluminum don babban kayan ado a cikin kayan ado na ciki, harabar otal, asibiti da makaranta. Yana da ƙarfin ƙarfe mai ƙarfi, bambancin launi da kwanciyar hankali.

Taƙaitaccen bayanin kwararar tsari:

(1) Degreasing: saboda tabon mai manne da extruded aluminum profile a lokacin sarrafawa, ajiya da kuma sufuri zai samar da wani fim mai a saman da substrate, a daya hannun, shi zai tasiri adhesion tsakanin surface rufe Layer da. karfe a cikin substrate, a gefe guda, zai rage ƙarfin da ke tsakanin spraying Layer da substrate, don haka ana buƙatar maganin ragewa. Ana amfani da Sulfuric acid (H2SO4) don cire mai, kuma babban taro shine 100g / L. ƙayyadaddun ƙaddamarwa ya dogara da kayan aiki da buƙatun ingancin bayanin martaba na aluminum. Ba a maye gurbin ruwan tanki kuma kawai yana buƙatar ci gaba da ci gaba a lokuta na yau da kullun. Yayin da ake aiwatar da aikin ragewa a cikin dakin da zafin jiki kuma an ƙara mai hana acid hazo, ana haifar da wani adadin ƙwayar acid a cikin wannan tsari. Wannan tsari yana haifar da maye gurbin acid acid.

(2) Tsabtace wucewa guda uku: bayan cire man fetur, ana yin wankan ruwa a cikin tankin wanke ruwa. Akwai tankunan wanke ruwa guda 3 gabaɗaya, kuma ana ɗaukar hanyar wankin ruwan da ke gaba da juna. Sabili da haka, ana samar da ruwa mai tsabta na acid a cikin wannan tsari.

(3) Lalacewar Alkali da tsaftacewa na biyu: cire fim din oxide akan saman bayanin martabar aluminum ta hanyar lalatawar alkali mai ƙarfi. Tsarin lalatawar alkali shine halayen exothermic, don haka ana saita na'urar anti-lalata a cikin tankin lalata alkali, kuma ana amfani da jaket ɗin ruwan sanyi don kwantar da ruwa mai lalata alkali. 40g / L sodium hydroxide bayani da ake amfani da alkali lalata. Za a haifar da hazo a lokacin da ake lalata alkali kuma za a shiga hasumiya ta hazo na alkali don sha da maganin tsarkakewa. Bayan lalatawar alkali, yana buƙatar tsaftace shi da ruwa, tsaftacewa mataki biyu da wanke ruwa mai ƙarfi don cire ragowar alkali a saman da samar da ruwan sha na alkaline.

(4) Neutralization da tsaftacewa mataki daya: ash rataye a kan substrate surface bayan alkali lalata, don haka 50g / L sulfuric acid bayani ake bukata domin acid pickling neutralization. Manufar neutralization shine daidaita ƙimar pH na farfajiyar ƙasa. Tun lokacin da aka aiwatar da tsarin tsaka-tsaki a cikin dakin da zafin jiki, ƙwayar sulfuric acid ba ta da yawa, kuma an ƙara mai hana acid hazo, an haifar da ƙananan ƙwayar acid a cikin wannan tsari; Bayan an cire shi, ana buƙatar wanke shi da ruwan famfo, kuma ana amfani da hanyar leaching don cire ragowar acid a saman don samar da ruwa mai wanke acid.

(5) Oxidation da tsaftacewa na biyu: an kafa fim din aluminum oxide mai yawa a saman aluminum don hana lalata. A anodizing electrolyte ne 150g / L sulfuric acid. Ka'idar oxidation ita ce samar da oxygen da hydrogen ta hanyar lantarki ta ruwa. Oxygen na farko yana amsawa a saman bayanin martaba na aluminum don samar da fim din aluminum oxide. A lokaci guda, lokacin da hydrogen ya cika, za a fito da acid sulfuric don samar da hazo na acid kuma a shiga hasumiya ta hazo na acid don maganin tsarkakewa.

Zazzabi na ruwan tanki mai iskar shaka zai tashi a ƙarƙashin aikin na yanzu kai tsaye. Don sarrafa wani zafin jiki na tanki na iskar shaka (tsarin yana buƙatar kiyaye yanayin ruwa a kusan 20 ℃), an saita murhu mai lalatawa a cikin tankin oxidation kuma ana amfani da jaket na ruwa don kwantar da ruwan tanki na iskar shaka. .

Bayan oxidation, za a yi amfani da ruwan famfo don wankewa. Ka'idar tsaftacewa iri ɗaya ce da "wanke ruwa mai mataki biyu" bayan lalatawar alkali don cire ragowar acid a saman da samar da ruwan sha mai tsabta na acidic.

(6) Dyeing da countercurrent tsaftacewa: bisa ga abokin ciniki ta bukatun, da aluminum profile bukatar da za a rina bayan hadawan abu da iskar shaka. Dangane da launuka daban-daban, an saita tankunan rini guda shida a cikin aikin. Ana yin rini ta hanyar rini na nutsewa a cikin ɗaki. Ana jika shi a cikin tankin rini na tsawon mintuna 1 ~ 3 gwargwadon zurfin launi, sannan a fitar da shi ya bushe. Rini na aikin sun ƙunshi rini mai haɗaɗɗiyar ƙarfe, dextrin, sodium acetate, da sauransu. bisa ga rahoton gwajin SGS na rini, ba a gano wani ƙarfe mai nauyi kamar gubar, mercury, cadmium da chromium hexavalent a cikin rini ba. Bayan rini, za a yi amfani da ruwa mai tsabta don tsaftacewa. Tsarin tsaftacewa na baya-bayan nan yana samar da tsabtace ruwa mai tsabta.

(7) Matsakaicin zafin jiki na al'ada, matsakaicin matsakaicin zafin jiki da tsaftacewa mataki biyu: manufar rufewa shine canza tsarin crystal na alumina membrane kuma sanya tsarin tsarin crystal na alumina membrane m. A cikin wannan aikin, za a gudanar da hatimin zafin jiki na al'ada da matsakaicin matsakaicin zafin jiki bisa ga zurfin bayanin martaba, za a yi maƙalar zafin jiki na yau da kullum don launi mai haske da matsakaicin matsakaicin matsakaici don launi mai duhu. Ana amfani da nickel acetate azaman wakili na rufe pore. Lokacin da ƙimar pH ta kusan 5.8, nickel acetate yana hydrolyzed don samar da nickel hydroxide, wanda aka tallata a buɗewar micropore, wanda zai iya cimma manufar rufewar pore daidai. Matsakaicin zafin jiki na rufe rami yana ɗaukar dumama lantarki. Akwai tsagi mai rufewa guda biyu: tsagi na rufe zafin jiki na al'ada da tsagi na matsakaicin zafin jiki. Ruwan tsagi baya buƙatar maye gurbinsa, amma kawai yana buƙatar ci gaba da haɓakawa a lokuta na yau da kullun.

Bayan matsakaicin matsakaicin zafin jiki, za a tsaftace rami sau biyu tare da ruwan zafi don cire ragowar nickel acetate a saman. Tsabtace ruwan zafi yana ɗaukar dumama lantarki don sarrafa zafin ruwa. Wannan tsari yana samar da tsabtace ruwa mai tsabta.

(8) bushewa: cire damshin da ke saman sassan da ke rufewa, sannan a yi amfani da dumama wutar lantarki don bushewa.
