Mashiinka anodizing tayo sare leh semi auto aluminium anodizing line
① Daaweynta dusha aluminium profile:
Daaweynta dusha sare ee profiles aluminium, oo sidoo kale loo yaqaan pretreatment dusha sare, waa in la isticmaalo walxaha jirka iyo kiimikooyinka si looga saaro wasakhda dusha sare ee profiles aluminium, si jidhka aluminium profile u soo baxo, taas oo ku habboon daaweynta oksaydhka dambe ee aluminium dusha profile.
② Nidaamka hoos u dhigista astaanta aluminiumka:
Ujeedada habka dereasing ee profiles aluminium waa in meesha laga saaro saliidda saliidda warshadaha iyo saliid anti-daxalka dushiisa ee profiles aluminium, iyo sidoo kale wasakh iyo wasakh u hoggaansamaan dusha profiles, si loo hubiyo in daxalka alkali uniform of profiles aluminium, iyo si loo hubiyo nadaafadda haamaha etching alkali;iyo si loo hagaajiyo tayada daaweynta dusha sare ee profiles aluminium.
③ Nidaamka xoqidda aashitada profile aluminium:
Habka etching acid ee dusha sare ee profiles aluminium waa in la sameeyo daaweynta daxalka aashitada oogada ka dib markii la dhimay profiles aluminium.Ujeedada ugu weyni waa in meesha laga saaro oksaydhyada la sameeyay ka dib markii oksaydhka walxaha kale ee birta ah ee dusha sare ee aluminium aluminium iyo filimada oxide ay si dabiici ah u sameeyeen profiles;waxay u baahan tahay isla markiiba ka dib daaweynta daxalka aashitada.Samee biyo dhaqid, heerkulka biyaha dhaqida waxaa la xakameynayaa ugu horeyn 50 °C si looga fogaado calaamadaha socodka ee dusha sare ee astaanta, ka dibna ku nadiifi biyo qulqulaya.Maaddaama astaanta aluminiumku ay ka kooban tahay curiye naxaas ah, dusha ayaa noqda mugdi ka dib daxalka aashitada, waxaana loo baahan yahay in lagu qooyo nitric acid 3-5 daqiiqo si dusha looga dhigo lacag dhalaalaya.
④ Habka qashin-qubka ee aluminium profiles:
Ujeedada ugu weyn ee habka etching alkali profiles aluminium waa qiyaastii la mid ah habka etching acid, in meesha laga saaro walxaha haraaga ah iyo lakabyada metamorphic ee dusha sare ee profiles aluminium inta lagu guda jiro habka oksaydhka, iyo in la baabi'iyo cilladaha xoq ka tagay on the dusha sare ee aluminium profiles inta lagu jiro habka extrusion;Daawaynta alkali etching ee dusha sare waxay door muhiim ah ka ciyaartaa tayada guud ee astaanta aluminiumka.
⑤ Habka dhexdhexaadinta astaanta aluminium:
Ujeedada habka dhexdhexaadinta profile aluminium waa in laga saaro naxaasta, manganese, birta, silicon iyo walxo kale oo aluminium ah ama wasakh ah oo ku sii jira dusha sare ee profile aluminium ka dib markii aysidhka iyo alkali etching daawaynta, kuwaas oo aan milmin xalalka alkaline, iyo dhexdhexaadin profile aluminium.Caleenta soo hadhay ka dib daawaynta etching alkaline guud ahaan waxaa loo isticmaalaa in lagu isticmaalo 30%-50% nitric acid.Silikoon aluminium alwaax ah oo sarreeya, ku tuur alloys, adigoo isticmaalaya isku dhafka nitric acid iyo hydrogen fluoride ee saamiga mugga 1: 3 acid.Silikoonku wuxuu la falgalaa hydrogen iyo hydrofluoric acid si uu u sameeyo fluorosilicic acid kana tago dusha aluminiumka.
⑥ Daaweynta Anodizing ee profiles aluminium:
Habka anodizing profile aluminium waa in la isticmaalo xalka sida dhexdhexaad ah, oo loo isticmaalo dheecaan caarada si ay u sameeyaan filim oxide ah oogada sare ee profile aluminium, si profile aluminium uu leeyahay iska caabin super daxalka, sababtoo ah lakabka ilaalinta la helay. by profile aluminium anodized Waxay leedahay adkeysi sare iyo iska caabin daxalka, iyo dhumucda caadiga ah waa 10-12μ, taas oo si fiican u hagaajin kara caabbinta oksaydhka ee profiles aluminium iyo hagaajinaysaa bilicsanaanta profiles.
Sulfuric acid anodization sida caadiga ah isticmaalaa 10-20% H2SO4 sida electrolyte ah, heerkulka shaqada waa 15-20 ℃, cufnaanta hadda waa 1-2.5A / dm2, iyo waqtiga electrolysis ku xiran tahay shuruudaha dhumucda filimka, guud ahaan 20-60min.Isha ugu badan ee korantadu waa mid toos ah.Korontada la dabaqay way kala duwan tahay iyadoo ku xidhan laawashiyaha, heerkulka iyo waxa ku jira aluminium ee elektrolytka.Guud ahaan, waa 15-20V.Halbeegyada habraaca ayaa saameyn weyn ku leh waxqabadka xuubka.
⑦ daawaynta daboolida astaanta astaanta aluminium:
Ka dib markii astaanta aluminiumka la anodized, micropores ayaa laga samayn doonaa dusha sare, taas oo sahlan in la oksijiyeen oo la daxaleeyo inta lagu jiro isticmaalka.Daawaynta xidhitaanka waa in la sameeyaa ka dib daaweynta anodizing.Habka daloolku wuxuu ka yimaadaa Yurub), sulfuric acid anodizing sida caadiga ah wuxuu isticmaalaa 10-20% H2SO4 sida elektrolytka, heerkulka shaqada waa 15-20 ℃, cufnaanta hadda waa 1-2.5A / dm2, waqtiga korantada waxay kuxirantahay dhumucda filimka shuruudaha, guud ahaan 20-60min.Isha ugu badan ee korantadu waa mid toos ah.Korontada la dabaqay way kala duwan tahay iyadoo ku xidhan laawashiyaha, heerkulka iyo waxa ku jira aluminium ee elektrolytka.Guud ahaan, waa 15-20V.Halbeegyada habraaca ayaa saameyn weyn ku leh waxqabadka xuubka.
