high quality anodizing muchina semi auto aluminium anodizing line
①Aluminium mbiri yepamusoro kurapwa:
Kurapa kwepamusoro kwealuminium profiles, inozivikanwawo seyepamusoro pretreatment, kushandisa zvinhu zvemuviri uye zvemakemikari kubvisa tsvina iri pamusoro pealuminium profiles, kuitira kuti iyo aluminium profiles iburitswe pachena, iyo iri nyore kune gare gare oxidation kurapwa kwealuminium. profile surface.
②Aluminium mbiri yepasi degreasing maitiro:
Chinangwa chekubvisa mafuta ealuminium profiles ndechekubvisa maindasitiri ekuzora mafuta uye anti-corrosion mafuta pamusoro pealuminium profiles, pamwe netsvina uye kusvibiswa kunonamira pamusoro pemaprofiles, kuve nechokwadi chekuora kwealkali kwealuminium profiles, uye kuve nechokwadi chehutsanana hwe alkali etching matangi;uye kuvandudza kunaka kwekurapa kwealuminum profiles.
③Aluminium mbiri asidhi etching maitiro:
Iyo acid etching process pamusoro pealuminum profiles ndeyekuita pasi acid corrosion kurapwa mushure mekubvisa mafuta ealuminium profiles.Chinangwa chikuru ndechekubvisa maokisi akaumbwa mushure meiyo oxidation yezvimwe zvinhu zvesimbi pamusoro pearuminiyamu profiles uye iyo oxide mafirimu anongo umbwa nemaprofiles;inoda kuva pakarepo mushure mekurapwa kweasidhi yekuora.Ita kugeza mvura, uye tembiricha yekugeza mvura inodzorwa nekukurumidza kusvika 50 °C kudzivirira kuyerera mamaki pamusoro peiyo profil, uye wobva wachenesa nemvura inoyerera.Sezvo iyo aluminium profil ine copper element, iyo nzvimbo inosviba mushure mekuora kweasidhi, uye inoda kunyikwa munitric acid mhinduro kwemaminetsi matatu-5 kuti iite sirivha yakajeka.
④Alkaline etching maitiro ealuminium profiles:
Chinangwa chikuru che alkali etching process yealuminium profiles yakangofanana neiyo acid etching process, kubvisa zvakasara zvinhu uye metamorphic layers pamusoro pearuminiyamu profiles panguva yeoxidation process, uye kubvisa kukwara kwakasara pa. pamusoro peiyo aluminium profiles panguva ye extrusion process;Iyo yepamusoro alkali etching kurapwa inoita basa rakakosha mumhando yese yealuminium profiles.
⑤Aluminium profile neutralization process:
Chinangwa chealuminium profile neutralization process ndechekubvisa mhangura, manganese, simbi, silicon uye zvimwe zviwanikwa zvealloy kana tsvina inoramba iri pamusoro peiyo aluminium profiles mushure me acid etching uye alkali etching kurapwa, izvo zvisinganyunguke mualkaline solution, uye gadzirisa iyo aluminium profile.Iyo lye inosara mushure me alkaline etching kurapwa inowanzo shandiswa kushandisa 30% -50% nitric acid mhinduro.Pamusoro pearuminiyamu yearuminiyamu yesilicon yakakwira, kandwa mumisanganiswa, uchishandisa musanganiswa wenitric acid nehydrogen fluoride muchiyero chevhoriyamu che1:3 asidhi.Silikoni inopindirana nehydrogen uye hydrofluoric asidhi kuumba fluorosilicic acid uye kusiya aruminiyamu pamusoro.
⑥Anodizing kurapwa kwealuminium profiles:
Iyo nzira yeanodizing iyo aluminiyamu mbiri ndeye kushandisa mhinduro senge svikiro, uye shandisa iyo tip discharge kuumba oxide firimu pamusoro peiyo aluminium profiles, kuitira kuti iyo aluminium profile ine super corrosion resistance, nekuda kwechidziviriro chakawanikwa. neanodized aluminium profile Iine hurema hwakanyanya uye kusagadzikana kwekuora, uye chiyero chepamusoro ndeye 10-12μ, iyo inogona kuvandudza zviri nani kupikisa kweoxidation yealuminium profiles uye kugadzirisa aesthetics yeprofiles.
Sulfuric acid anodization inowanzoshandisa 10-20% H2SO4 se electrolyte, tembiricha yekushanda i15-20 ℃, density iripo i1-2.5A/dm2, uye nguva ye electrolysis inoenderana nezvinodiwa nefirimu ukobvu, kazhinji 20-60min.Inonyanya kushandiswa magetsi ndiyo yakananga ikozvino.Iyo voltage inoshandiswa inosiyana zvichienderana ne conductivity, tembiricha uye aluminium zvirimo zve electrolyte.Kazhinji, iri 15-20V.Maitiro ekugadzirisa ane simba guru pakushanda kwe membrane.
⑦ Aluminium profile surface sealing treatment:
Mushure meiyo aluminiyumu profil inodized, micropores ichaumbwa pamusoro, zviri nyore kuve oxidized uye corrod panguva yekushandiswa.Kuisa chisimbiso kurapwa kunofanira kuitwa mushure mekurapa anodizing.Iyo gomba maitiro anobva kuEurope), sulfuric acid anodizing inowanzoshandisa 10-20% H2SO4 se electrolyte, tembiricha yekushanda i15-20 ℃, density iripo i1-2.5A/dm2, nguva ye electrolysis inoenderana nekukora kwefirimu. zvinodiwa, kazhinji mu20- 60min.Inonyanya kushandiswa magetsi ndiyo yakananga ikozvino.Iyo voltage inoshandiswa inosiyana zvichienderana ne conductivity, tembiricha uye aluminium zvirimo zve electrolyte.Kazhinji, iri 15-20V.Maitiro ekugadzirisa ane simba guru pakushanda kwe membrane.
