mochini oa boleng bo holimo oa anodizing semi auto aluminium anodizing line
① Phekolo ea boemo ba aluminium:
Phekolo ea bokaholimo ba li-profiles tsa aluminium, tse tsejoang hape e le "pretreatment" ea holimo, ke ho sebelisa lintho tsa 'mele le tsa lik'hemik'hale ho tlosa litšila tse holim'a li-profiles tsa aluminium, e le hore 'mele oa profil ea aluminium o pepesehe, o loketseng kalafo ea morao-rao ea oxidation ea aluminium. bokaholimo ba boemo.
②Ts'ebetso ea ho hloekisa sefahleho sa aluminium:
Morero oa ts'ebetso ea ho tlosa mafura bakeng sa profiles ea aluminium ke ho tlosa oli e tlotsang ea indasteri le oli e thibelang ho bola holim'a li-profiles tsa aluminium, hammoho le litšila le litšila tse khomarelang holim'a li-profiles, ho etsa bonnete ba ho bola ha alkali ea li-profiles tsa aluminium. ho netefatsa bohloeki ba litanka tsa alkali etching;le ho ntlafatsa boleng ba kalafo ea bokaholimo ba li-profiles tsa aluminium.
③ Ts'ebetso ea ho qoelisa profil ea aluminium:
Ts'ebetso ea etching ea asiti holim'a liprofinse tsa aluminium ke ho etsa kalafo ea kutu ea asiti ka mor'a ho theola liprofaele tsa aluminium.Sepheo se seholo ke ho tlosa li-oxide tse entsoeng ka mor'a hore ho be le oxidation ea likarolo tse ling tsa tšepe holim'a likarolo tsa aluminium le lifilimi tsa oxide ka tlhaho tse entsoeng ke litlaleho;e hloka ho ba hang ka mor'a kalafo ea kutu ea acid.Hlatsoa ka metsi, 'me mocheso oa ho hlatsoa metsi o laoloa kapele ho 50 °C ho qoba matšoao a phallo holim'a profil, ebe o hloekisa ka metsi a phallang.Kaha profil ea aluminium e na le element ea koporo, bokaholimo bo ba lefifi kamora ho kutu ea asiti, 'me e hloka ho kolobisoa ka tharollo ea asiti ea nitric bakeng sa metsotso e 3-5 ho etsa hore bokaholimo bo be silevera.
④Ts'ebetso ea alkaline e kenyelletsang profilse ea aluminium:
Morero o ka sehloohong oa ts'ebetso ea alkali e etching ea profil ea aluminium e batla e tšoana le ts'ebetso ea acid e etching, ho tlosa lintho tse setseng le likarolo tsa metamorphic holim'a profil ea aluminium nakong ea ts'ebetso ea oxidation, le ho felisa mengoallo e setseng holim'a bokaholimo ba profil ea aluminium nakong ea ts'ebetso ea extrusion;Kalafo ea "alkali etching" ea holim'a metsi e bapala karolo ea bohlokoa ho boleng bo akaretsang ba profil ea aluminium.
⑤ Ts'ebetso ea ho se nke lehlakore ka aluminium:
Sepheo sa aluminium profil neutralization process ke ho tlosa koporo, manganese, tšepe, silicon le likarolo tse ling tsa alloy kapa litšila tse setseng holim'a profil ea aluminium ka mor'a phekolo ea acid e etching le alkali etching, e ke keng ea qhibiliha ka tharollo ea alkaline, le fokotsa profil ea aluminium.Lilae tse setseng ka mor'a phekolo ea alkaline etching hangata li sebelisoa ho sebelisa tharollo ea 30% -50% ea nitric acid.Bakeng sa li-alloys tse phahameng tsa silicon aluminium, lahleloa ka li-alloys, u sebelisa motsoako oa nitric acid le hydrogen fluoride ka tekanyo ea molumo oa 1: 3 acid.Silicon e kopana le hydrogen le hydrofluoric acid ho etsa fluorosilicic acid ebe e siea bokaholimo ba aluminium.
⑥Kalafo ea anodizing ea profiles ea aluminium:
Mokhoa oa ho anodizing profil ea aluminium ke ho sebelisa tharollo joalo ka seaplane, 'me u sebelise tlhahiso ea ntlha ho etsa filimi ea oxide ka holim'a profil ea aluminium, e le hore profil ea aluminium e na le khanyetso e kholo ea kutu, ka lebaka la lera le sireletsang le fumanoeng. ka profil ea aluminium ea anodized E na le boima bo phahameng le ho hanyetsa kutu, 'me botenya bo tloaelehileng ke 10-12μ, bo ka ntlafatsang ho hanyetsa ha oxidation ea profiles ea aluminium le ho ntlafatsa aesthetics ea profiles.
Sulfuric acid anodization hangata e sebelisa 10-20% H2SO4 e le electrolyte, mocheso o sebetsang ke 15-20 ℃, sekhahla sa hona joale ke 1-2.5A/dm2, 'me nako ea electrolysis e itšetlehile ka litlhoko tsa botenya ba filimi, ka kakaretso ke 20-60min.Mohloli o tloaelehileng oa matla ke motlakase o tobileng.Matla a sebelisoang a fapana ho ea ka conductivity, mocheso le aluminium content ea electrolyte.Ka kakaretso, ke 15-20V.Mekhahlelo ea ts'ebetso e na le tšusumetso e kholo ts'ebetsong ea lera.
⑦ Kalafo ea ho tiisa sefahleho sa aluminium:
Ka mor'a hore profil ea aluminium e tlosoe, li-micropores li tla thehoa holim'a metsi, tseo ho leng bonolo hore li be le oxidized le ho senyeha ha li sebelisoa.Ho tiisa kalafo ho lokela ho etsoa kamora kalafo ea anodizing.Ts'ebetso ea lesoba e tsoa Europe), anodizing ea sulfuric acid hangata e sebelisa 10-20% H2SO4 e le electrolyte, mocheso o sebetsang ke 15-20 ℃, sekhahla sa hona joale ke 1-2.5A/dm2, nako ea electrolysis e itšetlehile ka botenya ba filimi. litlhoko, ka kakaretso ka 20- 60min.Mohloli o tloaelehileng oa matla ke motlakase o tobileng.Matla a sebelisoang a fapana ho ea ka conductivity, mocheso le aluminium content ea electrolyte.Ka kakaretso, ke 15-20V.Mekhahlelo ea ts'ebetso e na le tšusumetso e kholo ts'ebetsong ea lera.
