Anodized thiab Hmoov Coated Aluminium technology raws li ib tug ntau nto kev kho mob nyob rau hauv lub electroplating kev lag luam thiab lub ntsiab technology, dav siv nyob rau hauv lub electroplating kev lag luam. Nyob rau hauv Feem ntau, hlau neeg xws li txhuas qhov chaw, nyob rau hauv thiaj li yuav tau zoo deg zog thiab gloss, feem ntau ntawm uas muaj rau undergo Anodized thiab Hmoov Coated Aluminium txheej txheem, nyob rau hauv nws saum npoo them nrog ib tug txheej ntawm tuab thiab muaj ib tug tej yam degree ntawm gloss ntawm tus hlau oxide zaj duab xis, xws li npib tsib xee zaj duab xis thiab thiaj li nyob. Nyob rau hauv lub anodic oxidation txheej txheem, ib tug hlau xws li npib tsib xee los yog cov zoo li yuav tsum tau plated yog feem ntau yog siv raws li ib tug anode, thiab ib tug hlau neeg xws li txhuas los yog cov zoo li yuav tsum tau plated yog siv raws li ib tug cathode, thiab cov electrons yuav tsum tau metallized ntawm lub anode yog electrified rau npib tsib xee ions los ntawm electrochemical txoj kev, Nyob rau hauv lub hluav taws xob field nyob rau hauv lub cover rau tus hlau qhov chaw tau plated, thiaj li mus ua kom tiav lub plating ntawm hlau Cheebtsam ntawm lub plating txheej txheem.
Nyob rau hauv kev, nws yog tsim nyog los degrease cov hlau neeg nrog rau cov acid thiab alkali ua ntej lub anodic oxidation kauj ruam, thiab tom qab lub anodic oxidation, nws yog tsim nyog los raug lub Plated hlau neeg nto sib khi kev kho mob. Tam sim no, feem ntau ntawm cov electroplating qhauj siv npib tsib xee acetate raws li ib tug sealing neeg sawv cev. Nyob rau hauv tus txheej txheem no, qhauj yuav tsim ib tug ntau ntawm degreasing wastewater, acid thiab alkali khib nyiab dej thiab npib tsib xee-muaj wastewater. Cov twj muaj ib tug hauv chav kawm ntawv ntawm tus kab mob npib tsib xee uas yog nruj me ntsis tshuaj los ntawm lub xeev thiab yuav tsum yog li ntawd yuav zoo pov tseg ua ntej nws yuav tawm.
Anodized dyeing txheej txheem ntawm Tuag Casting Aluminium Alloy
Cov kev loj hlob ntawm lub Anodized thiab Hmoov Coated Aluminium txheej txheem ntawm tus tuag-casting txhuas hlau yog nyuaj tshaj lub oxidation txheej txheem ntawm qhov dog dig txhuas vim hais tias ntawm qhov chaw thaj chaw ntawm tus tuag casting muaj ntau nyuab, xws li cov xuab zeb qhov, lub keej, lub oxidizing impurity, qhov kev tso tawm neeg saib xyuas thiab cov roj deg kev kho mob yog feem ntau tsis tau daws tau qhov teeb meem, los kov yeej tej teeb meem no yuav tsum yog los ntawm tus tuag-casting khoom technology pib, txoj kev loj hlob ntawm ib tug ntau ntawm ruaj nto kev kho mob ntawm phoov los mus kov yeej qhov teeb meem no, peb los ntawm ib tug loj tus naj npawb ntawm cov qauv, tau tsim ib tug tuag-cam khwb cia rau txhuas hlau cov khoom yuav kaj lug, Anodized coloring kev daws teeb meem los pab cov neeg muas zaub lug txhim khu cov competitiveness ntawm lawv cov khoom thiab txhim khu lub ntxiv nqi ntawm lawv cov khoom!
Ua ntej, cov kev xaiv ntawm tuag-casting ntaub ntawv
Feem ntau siv tuag-casting txhuas txhuas, txhuas, txhuas, txhuas thiab zinc hlau. Ib txhia neeg sim siv ntshiab txhuas thiab Cheebtsam ze rau 6063 cov ntaub ntawv rau zus tau tej cov tuag-casting khoom, thiab ces ua sulfuric acid Anodized thiab Hmoov Coated Aluminium txheej txheem, lub me me batch ntawm ntau lawm qhia tau hais tias: tuag casting tom qab ib tug complex anode kev kho mob, lub oxide zaj duab xis txheej tsis muaj kob thiab pob tshab, deg finish yuav ncav cuag rau hauv daim iav lub xeev yuav tsum dyed ntau yam ntawm cov xim; tab sis tus tuag-casting zus tau tej cov nyias-walled, me ntsis ntau qhov chaw hauv lub qauv, lub phenomenon ntawm tej kab nrib pleb yog 100% ntawm cov hav zoov ntawm yuav luag tsis muaj lawm nto kev kho mob;
ADC12 / ADC10 ua tus tshaj mature tuag-casting txhuas hlau, tuag-casting tsis xws luag no kuj me me, cov khoom ua tau zoo yog tus ruaj khov, ua ke nrog peb cov kev loj hlob ntawm tuag-casting txhuas hlau tshuaj polishing neeg sawv cev, yog tshwj xeeb yog haum rau tuag casting Anodized thiab hmoov Coated Aluminium pretreatment txheej txheem, ADC12 / ADC10 tsuas yog ua tau, haum rau dyeing ntau yam xim. Nyob rau hauv kev, tus qauv ADC10 tuag castings tau sib polished rau daim iav nyhuv, ADC12 muaj zoo machinability tab sis tsis tshua muaj thermal conductivity! ADC10 yog zoo dua ADC12, tab sis tus nqi yog siab! Nyob rau hauv qhov tseeb, ADC10 yog A380 thiab ADC12 yog A383. (ADC12 sib npaug mus rau Suav-ua hlau code YL113, hlau qib yog YZAlSi11Cu3, lub US hlau qib yog 383), ADC10 casting, zoo siab, haum rau qhov siv thiab ua loj tuag castings. Nws txhua yam khoom thiab zoo txiav, tab sis me ntsis tsawg xeb kuj. ADC12 thiab ADC10 piv nrog rau qhov nyiaj ntawm Si, lub yav tas 9.6% mus rau 12.0%, lub tom kawg 7.5% mus rau 9.5%, lub yav tas los yam nyob rau hauv lub eutectic point nyob ib ncig ntawm lub alloy ntawm qhov zoo tshaj plaws muaj, li ntawd, haum rau tuag-casting complex castings, nws High zog, zoo siab kuj, kub brittleness me me. ADC12 / ADC10 silicon muaj siab tooj liab cov ntsiab lus, kev siv cov zoo tib yam sulfuric acid electrolysis oxidation txheej txheem thiab tsaus ntuj nti grey. Lub ntsiab yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov tsos yog tooj liab, pob zeb ntais, chromium, hlau, zinc, manganese thiab lwm yam hlau ntsiab, cov hlau ntsiab nyob rau hauv lub txhuas cov ntsiab lus ntawm qhov tsawg, tom qab anodic oxidation ntawm txoj kev kaj lug thiab ntxuav lub zoo dua, Tus nyob rau hauv qhov tseeb, qhov kev tsim nyog nce nyob rau hauv nyob tus yeees ntawm tooj liab thiab silicon tsis tau tsuas yog txhim kho txoj kev tuag-casting tsis xws luag, tab sis kuj ua rau kom tus nplaim lub ci, los txhim kho lub uniformity ntawm lub fineness ntawm cov khoom, conducive mus nto kev kho mob, zinc thiab magnesium tshuaj thaj chaw ntawm cus ciav yuav tsum tau nruj me ntsis tshuaj, txwv tsis pub kom qhov teeb meem ntawm anodic oxidation;
Ntawm cov hoob kawm, ib tug tsim nyog xaiv ntawm tuag-casting neeg saib xyuas thiab tuag-casting molding txheej txheem tsis, yog lub casting ntawm anodic oxidation ntawm qhov tsim nyog tej yam kev mob.
Ob, lub pre-kev kho mob
1, polishing thiab leveling: kev siv ntawm cov neeg kho tshuab polishing txoj kev yuav siv tau ntxhib daim ntaub los yog zoo polishing, Sandblasting los yog kev co sib tsoo, sib nqus sib tsoo, tau tiaj tus thiab kaj tsos. Muaj manufacturers siv high-siab pab kiag li lawm yuav tsum tau ntxuav nrog dej thiab iav xuab zeb tsuag mus rau qhov chaw ntawm cov khoom mus cuag lub hom phiaj ntawm tu thiab finishing, nrog zoo kawg li tshwm sim.
2, nyob rau hauv tas li ntawd mus ciab: polished tom qab lub workpiece nyob rau hauv ib tug tshwj xeeb tu neeg sawv cev rau tshem tawm cov workpiece nto kom tshem tawm cov polishing muab tshuaj txhuam thiab polishing av, tab sis kuj ntxuav tam sim ntawd tus workpiece yog tsis txuas mus rau ib tug ntau yam ntawm cov roj.
HTL-210 20-50 g / L TEMP: 50-65 ° C Lub sij hawm: 3-10 min
3, degreasing degreasing alkaline xeb: rau tshem tawm ntawm qhov chaw ntawm lub workpiece oxide, los ntawm lub hom neeg uas sawv cev los mus tiv thaiv cov khoom tom qab lub ntuav fouling;
Degreasing: HTL-310 20-25 g / L TEMP: RT Lub sij hawm: 3-10min
Tsis muaj zog: HTL-310 50-60 g / L TEMP: 60-75 ℃ Lub sij hawm: 3-5min
4, thiab nyob rau hauv tas li ntawd: nyob rau hauv tas li ntawd mus rau dub thiab grey
HNO3 (68%) 300-500 ml / L HTL-320 30-50 g / L TEMP: RT Lub sij hawm: 1-3 min
Cov tshuaj tiv thaiv mechanism: tsis muaj zog yaig tom qab lub workpiece yuav tsim ib tug txheej ntawm dub zaj duab xis, txoj kev no yuav tshem tawm cov dub thiab grey
5, rau immersion HTL-328 Tshuag tshuaj siv TEMP: <40 ℃="" lub="" sij="" hawm:="">
Kiag li tshem tawm ntawm qhov chaw ntawm lub workpiece dub zaj duab xis, raug tus txhuas nto, kom tsis txhob impurities mus rau hauv lub kav dej phwj mus rau hauv lub qhov
4, tshuaj polishing (nrog triacylated kuj tsis tshua muaj daj haus luam yeeb ib qho yooj yim los tswj)
HNO3 (68%) 650-800 ml / L HTL-330 120-150 g / L TEMP: 90-95 ° C Lub sij hawm: 1-3 min
Ua kom cov brightness, txo lub lwm yam nyob sab nraum lub txhuas, ib qho yooj yim mus oxidize lub coloring
