Yadda anodized aluminum

Mass samar da aluminum Tsarin da sassa saboda da musamman Properties wannan abu. Yana yana da mafi ƙasƙanci musamman nauyi, resistant zuwa yawa lalatattu yanayin da saukin sarrafa. Amma tsawon rai kayayyakin bukatar anodized aluminum.

Me shi ake bukata

A lokacin hulda da wani karfe tare da oxygen a yanayin auku a farfajiya na topsheet hadawan abu da iskar shaka. Wannan shi ake kira da samuwar da oxide fim, wanda ya hana yaduwa a ciki da karfe tsatsa.

Dangane da kayan surface hadawan abu da iskar shaka tsari ne daban-daban. Iron da karfe da aka kusan kafa na oxide film, amma daraja karafa (zinariya, da azurfa, platinum) an kare da lalata. Aluminum daukan tsakiyar matsayi, don haka da bukatar wucin gadi halittar fim. Wannan yana da muhimmanci musamman idan yi na windows zai nema a irin wannan profile. Anodized aluminum ne resistant zuwa waje yanayin dalilai wanda zai iya sa lalata da kuma m asarar yi Properties daga cikin tsarin.

fasahar

Domin samar da tasiri a kan airfoil surface m film na bukatar anodizing aluminum. Jigon da aiwatar ta'allaka ne a dauke kwayoyin na wani abu da yake mafi resistant da sakamakon oxygen a cikin tsarin da samfurin. Bugu da kari, yana yiwuwa a artificially cika da oxide Layer ba tare da Bugu da kari na sauran karafa.

Kõwane Hanyar kana bukatar ka cika a kan yanayin da tsari. Ya kunshi wadannan matakai:

1. Preparatory.
2. Kan aiwatar da anodization.
3. Matabbatarta Layer.

Ga kowane daga cikinsu zabi da ya dace kayan aiki da kuma kayayyaki. A sakamakon haka, ya kamata a sami wani high quality-Anodized aluminum. Wannan zai ba da damar amfani da profile domin samar da facade da taga kayayyaki.

A shiri lokaci

Samfurin surface ne sosai tsabtace daga turɓãya, datti da tarkace. Idan akwai magudi ko inji lalacewa, suna shafe ta ko da a gaban anodization. Bugu da ari, ya kamata a cire tsohon oxide Layer, in ba haka ba za su tsoma baki tare da samuwar wani uniform m film.

Bayan da machining (nika da degreasing), da profile dole ne a sanya a cikin wani alkaline bayani. Don yadda ya kamata anodized aluminum, dole ne ka farko cika da "etch" surface. Formation mikrokavern magudi kuma qara overall yanki na m Layer. Bugu da ari bayani na samfurin da aka yi a wani acidic bayani. Bayan kammala dukkan bulan na aluminum ya kamata a taku ta fannin rinsed.

anodizing

Bayan wucewa ta cikin shiri lokaci yana yiwuwa ya fara da anodizing tsari. Don yin wannan, aluminum kayayyakin an nutsa cikin zurfin musamman wanka. A hanya aka yi tare da taimakon crane kayan aiki (na manyan Tsarin) ko da hannu ta hanyar wayoyi.

Game da wanka zane ya kamata a tattauna dabam. Yana buga wani m damar a lokacin farin ciki-walled bakin karfe ga abin da cathode 2 da aka sanya. Profile nutsewa fasahar dole ne irin wannan cewa electrolyte a cikin wanka a lamba tare da dukan yankin na samfur. Kamar yadda irin wannan wani ruwa sulfuric acid da aka yi amfani da, wanda sanya musamman bukatar a samar aminci. Idan samfur yana mai rikitarwa sanyi, shi ne mafi alhẽri amfani da oxalic acid.

Bayan nutsewa profile electrolysis fara da nunawa wani m Layer. Its kauri ya dogara da abun da ke ciki na electrolyte, zafin jiki da kuma na yanzu yawa. A mafi girma da karshen adadi, da ya fi girma da oxide film kafa a kan surface. Da zarar kammala Layer kauri iya bambanta daga 2 zuwa 7 microns, dangane da aiwatar da sigogi.

kayyade

Duk da haka, a wannan daina ma farkon anodizing aluminum - dole a gyara kafa surface Layer. Yana zai zama na attaching a porous tsarin abin da sauri ba tare da lura exfoliates. Bayan haka, ba dole wasu halaye na taurin.

Kayyade iya cika ta da ajiye da samfurin a cikin wani sabo ruwa kawo a tafasa yanayin. A cewar wani fasahar surface da aka bi da tare da zafi tururi. A cikin wani hali akwai wani kin amincewa da oxide fim da kuma ta kwayoyin fili tare da aluminum surface.

Idan a nan gaba profile za a fentin, ba za ka iya yi da bunqasar. Lokacin da ake ji da fasaha na caramel foda, da fim za a kare a sakamakon zafi magani.

Mun samu daga abin da anodized aluminum. Irin karfe machining - tabbacin da tsatsa a kan surface daga cikin samfurin. anodizing fasahar ne kullum inganta, da kuma a yau ba za ka iya yi da zane na aluminum kayayyakin da taimako na cathodic dauki.
