high quality anodizing inji Semi auto aluminum anodizing line
①Aluminum profile surface jiyya:
Jiyya na bayanan martaba na aluminum, wanda kuma aka sani da pretreatment, shine amfani da abubuwa na zahiri da na sinadarai don cire datti a saman bayanan martabar aluminum, ta yadda jikin profile na aluminum ya fito fili, wanda ya dace da maganin oxidation daga baya na aluminum. bayanin martaba.
②Aluminum profile surface ragewa tsari:
Makasudin aiwatar da tsarin lalata don bayanan martabar aluminum shine don cire mai mai mai da masana'antu da mai mai hana lalata a saman bayanan martaba na aluminum, da datti da ƙazanta waɗanda ke manne da saman bayanan martaba, don tabbatar da lalata alkali uniform na bayanan martaba na aluminum, da don tabbatar da tsabtar tankunan alkali;da kuma inganta yanayin kula da ingancin bayanan martaba na aluminum.
③Aluminum profile etching tsari:
Tsarin etching na acid akan saman bayanan martabar aluminium shine don aiwatar da maganin lalatawar acid bayan lalata bayanan martabar aluminum.Babban manufar ita ce cire oxides da aka kafa bayan oxidation na sauran abubuwan ƙarfe a saman bayanan martaba na aluminum da kuma fina-finai na oxide da aka samo asali ta hanyar bayanan martaba;yana buƙatar zama nan da nan bayan maganin lalata acid.Yi wankan ruwa, kuma ana sarrafa zafin wankan ruwa a farkon 50 ° C don guje wa alamun kwarara a saman bayanin martaba, sannan a tsaftace tare da ruwa mai gudana.Tun da bayanin martabar aluminum ya ƙunshi nau'in jan ƙarfe, saman ya zama duhu bayan lalata acid, kuma yana buƙatar jiƙa a cikin maganin nitric acid na mintuna 3-5 don sa saman ya zama azurfa mai haske.
④ Alkalin etching tsari na aluminum profiles:
Babban manufar alkali etching tsari na aluminum profiles ne wajen guda daya da acid etching tsari, don cire saura abubuwa da metamorphic yadudduka a saman da aluminum profiles a lokacin hadawan abu da iskar shaka tsari, da kuma kawar da karce lahani bar a kan. surface na aluminum profiles a lokacin extrusion tsari;The surface alkali etching jiyya taka muhimmiyar rawa a cikin overall ingancin da aluminum profile surface.
⑤ Aluminum profile neutralization tsari:
Manufar tsarin neutralization na bayanin martabar aluminum shine don cire jan ƙarfe, manganese, baƙin ƙarfe, silicon da sauran abubuwan gami ko ƙazantattun abubuwan da suka rage a saman bayanin martabar aluminum bayan etching acid da alkali etching, waɗanda ba su iya narkewa a cikin maganin alkaline, kuma neutralize da aluminum profile.Lye da ya rage bayan maganin alkaline etching ana amfani dashi gabaɗaya don amfani da maganin nitric acid na 30% -50%.Don manyan siliki na aluminium, jefa a cikin gami, ta yin amfani da cakuda nitric acid da hydrogen fluoride a cikin girman rabo na 1:3 acid.Silicon yana amsawa tare da hydrogen da hydrofluoric acid don samar da fluorosilicic acid kuma ya bar saman aluminum.
⑥ Anodizing jiyya na bayanan martaba na aluminum:
Hanyar anodizing bayanin martabar aluminum shine yin amfani da mafita azaman matsakaici, kuma amfani da fitarwar tip don samar da fim ɗin oxide akan saman bayanin martabar aluminum, ta yadda bayanin martabar aluminium yana da juriya na lalata, saboda kariyar da aka samu. by anodized aluminum profile Yana da high taurin da lalata juriya, da kuma misali kauri ne 10-12μ, wanda zai iya mafi alhẽri inganta hadawan abu da iskar shaka juriya na aluminum profiles da kuma inganta aesthetics na profiles.
Sulfuric acid anodization yawanci yana amfani da 10-20% H2SO4 a matsayin electrolyte, da aiki zafin jiki ne 15-20 ℃, da halin yanzu yawa ne 1-2.5A / dm2, da electrolysis lokaci ya dogara da fim kauri bukatun, kullum 20-60min.Mafi yawan tushen wutar lantarki shine kai tsaye.Wutar lantarki da aka yi amfani da ita ya bambanta dangane da ƙarfin aiki, zazzabi da abun ciki na aluminum na electrolyte.Yawanci, shi ne 15-20V.Siffofin tsari suna da tasiri mai mahimmanci akan aikin membrane.
⑦ Aluminum profile surface sealing magani:
Bayan an yi amfani da bayanin martabar aluminum, za a samar da micropores a saman, wanda ke da sauƙi don zama oxidized da lalata yayin amfani.Dole ne a gudanar da magani bayan anodizing magani.Ramin tsari ya samo asali daga Turai), sulfuric acid anodizing yawanci yana amfani da 10-20% H2SO4 a matsayin electrolyte, da aiki zafin jiki ne 15-20 ℃, da halin yanzu yawa ne 1-2.5A / dm2, da electrolysis lokaci ya dogara da fim kauri. bukatun, gabaɗaya a cikin 20-60min.Mafi yawan tushen wutar lantarki shine kai tsaye.Wutar lantarki da aka yi amfani da ita ya bambanta dangane da ƙarfin aiki, zazzabi da abun ciki na aluminum na electrolyte.Yawanci, shi ne 15-20V.Siffofin tsari suna da tasiri mai mahimmanci akan aikin membrane.
