Etching na aluminum a cikin gida

aluminum etching (kayayyakin da wannan ƙarfe) ne da za'ayi domin tsaftace shi daga cikin manya surface, ko da ba dole ba Layer na tsatsa. Har ila yau, har yanzu akwai ta iri-iri - art pickling lokacin da zama dole to sassaƙa mai juna a kan surface daga karfe sassa.

iri etching

Etching da karafa a general, kuma aluminum musamman, na iya zama na biyu main iri: sinadaran da electroplating. A karshen Hanyar ne da za'ayi kawai art.

A sinadaran: samfurin da aka sanya shi a cikin wani akwati wanda aka a baya zuba a cikin wani bayani da hydrochloric ko sulfuric acid. A cikin wannan hanya ta yin etching aluminum billet Alkali, misali sodium hydroxide.

A galvanic (in ba haka ba - electrolytic ko electrochemical) ya auku saboda wani lantarki baturi. A tsari kanta ne da za'ayi a cikin wani musamman wanka, inda akwai wani anode da wani cathode.

Next zuwa a yi la'akari kowane daga aluminum etch hanyoyin in more daki-daki. Har ila yau, gano wanda Hanyar ne mafi amintattu a gida.

Acid etching na aluminum

Saboda gaskiya cewa a cikin wannan tsari ake amfani da karfi acid, shi ne na farko Dole a cika tare da ƙara ranmu a lõkacin da aiki tare da su. Mai aiki dole ne sa safar hannu, mask, gaba-gaba. Yana da muhimmanci cewa dakin inda aiwatar da kanta suna da ventilated. Ba da ciwon wasu fasaha da kuma ba tare da wasu magunguna aiki tare acid da aka ba da shawarar.

Kamar yadda muka gani a sama, da samfurin da aka sanya shi a cikin wani aluminum ganga tare da wani acid. Mafi sau da yawa aluminum tare da sinadaran acid etching aiki da wadannan reagents: hydrochloric ko sulfuric acid. By maida martani su tare da hydrogen da aka saki karfe. Outwardly, shi ya dubi kamar haka: Product surface an rufe tare da kananan kumfa. Amma, bisa manufa, wannan za a iya hana ta ƙara a gaba da damar musamman sashi. Kamar wancan ne, da karfe ana kiyaye shi ta wani bakin ciki fim kumfa.

A matukar muhimmanci ga duk yadda ake gudanar acid pickling kayayyakin sanya daga aluminum dole ne a yi hanzari zuwa karfe surface kanta zauna m.

The bayyana Hanyar bada shawarar a cikin kwantena da aka yi da itace, ko kankare. A wannan yanayin da ciki surface dole ne a liyi tare da acid-resistant tiles haka kada su corrode da jirgin ruwa bango.

Wannan hanya ne amfani a yi shi ne ba da na kowa.

Etching na aluminum Alkali

A mafi yawan lokuta, a lokacin da wannan hanyar da ake amfani da wani ruwa-ruwa bayani daga sodium hydroxide (ba dole ba tare da ko ba tare da Additives).

Kuma aka yi amfani da su tsaftace surface na aluminum samfurin ko ba dole ba oxide man shafawa da kuma samu wani smoother (m ko Matte) surface.

Don me kuke bukatar haka sosai tsabtace? Don ƙãre samfurin (msl, na ado gine-gine da abubuwa, plaques) yana mai cikakken surface. Kuma ma, wannan hanya da ake amfani da gravure engraving.

Hanyar Alkali etching aluminum a hannu daya, shi ne isasshe low, amma shi ne sosai a lokacin cinyewa.

Features wannan hanyar

M mafita dauke daga hudu zuwa goma cikin dari na hydroxide. A zafin jiki a cikin etching wani Alkali ne game 40-90 digiri Celsius.

Idan dole, don samun wani haske kumfa shafi a kan wani workpiece, amfani da moisturizer ko musamman kari.

The talakawan zafin jiki a tsakiyar aiwatar - da sittin digiri. A karkashin irin wannan thermal yi ne a ingantaccen surface tsaftacewa.

Mafi kyau duka awo aluminum tsarki - 99,5%, da kuma taro na sodium hydroxide bayani - 10, 15, ko 20%.

Saboda haka, a lokacin da dauki aluminum narkar da a sodium hydroxide, da hydrogen da aka saki. A sakamakon haka ne a kumshin aluminate, kuma shi ne kawai wanzu a cikin Alkali bayani.

Bugu da ari matakai abin da ke faruwa a cikin etching wani Alkali

A wannan tsari, da adadin sodium hydroxide hankali zama karami. Kuma kamar haka ne rage-rage, kuma ya kwarara gudun da tsari, amma qara danko.

Bayar da cewa tanki ba ƙara sodium hydroxide, da dauki iya zama sosai m. Amma a karshen, ko wani brownish bayyananne bayani ga etching aluminum zama fari.

Kuma daga wannan lokacin aiwatar gudun aka ƙara.

A dauki aka precipitated alumina hydrate, wanda kama wani slurry. Kuma ma kasaftawa sodium hydroxide, wanda shi ne ma wajibi ne don etch aiwatar ci gaba.

Results a dauke Hanyar

Gwaje rubuce cewa sodium hydroxide bayani a karkashin ƙwazo da aikace-aikace a cikin etching aiwatar fara "sha" aluminum. Kuma shi ya faru idan dai da adadin caustic soda an rage wa rubu'i daga asali girma. Kuma bayan wannan tsari zai ci gaba da free caustic soda, komo acikin a cikin lambobin. Wannan, bi da bi, ya dogara da yawan zafin jiki, tsanani da kuma mita na yin amfani da Tashoshi (pauses).

A wannan yanayin, hydrate Falls sannu a hankali precipitate ko siffofin lu'ulu'u a kan kasa da kuma / ko bangarorin da ganga. A resultant hydrate ne isasshe m, kuma shi zai zama da wuya a cire. Wani lokaci sai ya yi jihãdi, kuma ya zaunar da kai tsaye a kan surface na dumama coils.

Akwai wani muhimmin batu, wadda ke da alaka da abun ciki na aluminum. A lokacin etching wannan karfe kayayyakin sodium hydroxide dole a bi da rabo daga aluminum hydroxide. Saboda mafi daga aluminum, don haka da tsari zai zama hankali. A m sharuddan da shi a fili yake cewa wajibi ne a kullum kara da adadin sodium hydroxide matsayin adadin aluminum a cikin jirgin ruwa.

Saboda haka, aluminum Alkali etching tsari za a iya ci gaba har abada. A asarar caustic soda zai faru ne kawai saboda ash shi tare da tururi.

Wannan hanya da aka zahiri amfani a m sharuddan. Amma akwai wasu nuances, wanda ya kamata ka manta da cewa daga lokaci zuwa lokaci don cire ƙẽƙashe laka hydrate. tsabtace da tace. tuna cewa ganga a wadda aiwatar a akai amfani da shi zai iya bauta wa ba fiye da shekaru biyu.

Ga sauran, wani rikitarwa a kan aikace-aikace na wannan hanya ba a saukar.

Total bayan sinadaran etching na aluminum workpiece surface shi wajibi ne don sosai kurkura kuma neutralize sauƙaƙa amfani 15-20% ƙarfi nitric acid bayani. Wannan tsari shine ake kira pickling.

A electroplating Hanyar

Na biyu Hanyar etching - galvanic. Shi ne mafi sauki da kuma lokaci ne da yawa sauri. Kuma sakamakon ne mai matukar high quality surface daga cikin samfurin, bayyananne shaci hoton (a Art Hanyar kamar yadda annabcin jinsunan).

A fasalin da wannan hanya shi ne cewa shi yana amfani da wani tushe na lantarki da makamashi (4-5 B).

Za ka kuma bukatar wanka da wannan size, saboda haka daidai da samfurin na aluminum. The abu na yi na baho, ya zama wani insulator. Abun da ke ciki na etching wanka don aluminum - wani bayani na jan karfe sulphate da sodium chloride.

Kafin fara aiwatar da preform dole ne a tsabtace da kuma degreased. Next, solder tin jan waya zuwa samfurin kuma ka runtse shi a sodium hydroxide bayani, sa'an nan - a wani sulfuric acid bayani. Bayan 2 minti kuma rinsed a karkashin iko da ruwan zafi ya kwarara. Yana haramta a wannan lokaci zuwa taba da samfurin.

Idan wasu sassa na workpiece ciyawa ne, ba wajibi ne su yi amfani da mastic. Sa'an nan za ka iya fara aiwatar.

Wannan hanya ya shafi biyu da ake kira goyan bayan, wanda dole ne a haɗe zuwa anode (m cajin) da kuma cathode (korau) ikon Madogararsa. Yana da muhimmanci cewa wadannan goyon bayan da aka sanya a fadin wanka. A kan goyon bayan da aka lazimta da anode na preform daga aluminum, da kuma na biyu - billet na wani daban-daban karfe.

Duk da wannan dama a cikin wanka da kuma kiyaye wani adadin lokaci. Sa'an nan wanke da turpentine da doobrabatyvaetsya nika da polishing.

art etching

Wannan irin plating Hanyar ne quite rare a zamanin yau. Tare da shi, za ka iya yin hakkin mallaka zane, zana rubutu, art kwafi, ado ga kowane workpiece na karfe.

Kuma sakamakon ne mai haske, kyakkyawan hoto. Abin da ya ce, marubucin yana da aiki, wanda zai iya barin kanka ko da sadaka.

asali image kanta, za ka iya zana naka, ko Buga (ta amfani da firinta Laser) a kan takarda. Next, a kan surface wani m tef sticked takarda da kurkura da ruwan zafi. Wadannan sakamakon na image kamata zama a kan m tef. Bar ta bushe. A halin yanzu, da bukatar shirya karfe surface ga abin da juna ne amfani - degrease ta barasa.

Sa'an nan manne da maƙale film patterned a farfajiya na workpiece, haka sakewa da shi daga iska kumfa. Barrantar zafi AWL haddi manne da kuma duk ba dole ba, fãce ga image kanta.

Etching ne da za'ayi a wata hanya wadda aka riga aka bayyana a sama - plated.

Lura: a lokacin da wannan tsari ne m don saki cutarwa gas, don haka mutane mafi fita daga cikin dakin.

Saboda haka, aluminum etch a gida ne m. Just zama tabbata ka bukatar ka yi dukan muhimmanci ranmu!
