Indasitiri yemhando yealuminium yemumaindasitiri yeChongqing yakura nekukurumidza mumakore achangopfuura, uye zvishoma nezvishoma yakatarisana nenyika yese. Tekinoroji yeanodizing ndeimwe yenzira dzinowanzo shandiswa muindasitiri yemhando yealuminium yemumaindasitiri yeChongqing. Vashandisi vatsva vazhinji havazivi zvakawanda nezvemaitiro eanodizing, saka ngatikupei sumo yakadzama.
Kuyerera kwemaitiro ekurapa oxidation yemaprofiles earuminiyamu eindasitiri muChongqing;
1. Kurapa pamusoro.
Kurapa pamusoro, kunozivikanwawo sekuti kurapa pamusoro, kubvisa tsvina iri pamusoro pearuminiyamu uchishandisa zvinhu zvepanyama uye zvemakemikari, kuitira kuti ikwanise kuratidzwa kune muviri wearuminiyamu, izvo zviri nyore kurapwa kweoxidation pamusoro pearuminiyamu muchikamu chekupedzisira.
2. Maitiro ekubvisa mafuta pamusoro.
Chinangwa chekubvisa mafuta mumafuta emumaindasitiri, mafuta anodzivirira kuora kwemafuta netsvina yakabatana nepamusoro pearuminiyamu, kuve nechokwadi chekuti aruminiyamu yakabatana nekupisa kwealkali uye kuchena kwetanki realkali. Kuvandudza kunaka kwekugadzirisa pamusoro pearuminiyamu.
3. Maitiro ekucheka asidhi.
Maitiro ekucheka pamusoro peasidhi ndeyekuita kurapwa kweacid pamusoro mushure mekubvisa mafuta paaruminiyamu, uye chinangwa chikuru chekubvisa ndechekubvisa oxide inoumbwa nekuoxidation yezvimwe zvinhu zvesimbi pamusoro pearuminiyamu profile uye oxide film yakagadzirwa nearuminiyamu; Mushure mekurapa acid corrosion, zvakakosha kuisuka nekukasika, uye tembiricha yekuwachisa inofanira kudzorwa 50℃ kare kudzivirira mavanga ekuyerera pamusoro pearuminiyamu, uye wozoichenesa nemvura inoyerera. Nekuti aruminiyamu profile ine mhangura, pamusoro payo panoita rima mushure mekuyedzwa kweacid corrosion, uye inoda kunyikwa mu nitric acid solution kwemaminitsi 3-5 kuti pamusoro payo pave nesirivha yakajeka.
4. Maitiro ekucheka alkaline.
Chinangwa chikuru che alkali etching process ndechekubvisa zvinhu zvakasara uye zvidimbu zvakachinja pamusoro pearuminiyamu profile panguva yekuoxidation, uye kubvisa zvikanganiso zvekukwenya zvinosara pamusoro pearuminiyamu profile panguva yekukanya. Kugadziriswa kwealkaline etching pamusoro pearuminiyamu profile kunoita basa rakakosha mumhando yepamusoro yearuminiyamu profile.
5. Maitiro ekusapindirana kwesimba.
Chinangwa chekubvisa tsvina kana zvinhu zvisina kuchena zvakaita semhangura, manganese, iron, silicon, nezvimwewo zvisinganyunguduke mualkaline solution inosara pamusoro pealuminium profile mushure mekuchekwa kweacid uye alkali etching. Kazhinji, nzira yekuchekwa kwealkaline solution inosara pamusoro pealuminium profile mushure mekuchekwa kwealkaline ndeyekushandisa 30%-50% nitric acid solution. Kune high-silicon aluminium alloy, musanganiswa we nitric acid nehydrogen fluoride ine volume ratio ye1: 3 inosarudzwa. Silicon inopindirana nehydrogen ne hydrofluoric acid kugadzira fluosilicic acid, iyo inosiya pamusoro pealuminium.
6. Kurapa kweanodizing.
Nzira yekurapa anodic oxidation ndeyekuti mhinduro inoshandiswa senzira, uye tip discharge inosarudzwa kuti igadzire oxide film pamusoro pealuminium profile, kuitira kuti aluminium profile ive ne super corrosion resistance. Nekuti protective layer inowanikwa neanodic oxidation yealuminium profile ine kuomarara kwakanyanya uye corrosion resistance, ukobvu hwakajairika i10-12μ m, izvo zvinogona kuvandudza zviri nani oxidation resistance yealuminium profile uye runako rwealuminium profile.
Maitiro ekugadzira anodic oxidation ane basa rakakosha mukunaka uye kugara kwenguva refu kwema profiles eChongqing industrial aluminum.
