Electroplating txheej txheem ntawm High Corrosion Resistance Zinc Alloy rau Nqus Electroplating Hluav Taws Kub Kub Tube
Zinc alloys xa mus rau alloys nrog zinc ua lub ntsiab tivthaiv thiab ib qho me me ntawm lwm cov hlau. Cov binary zinc alloys uas tau siv hauv kev tsim khoom yog: Zn-Ni, Zn-Co, Zn-Fe, Sn-Zn. Zn-Ti, Zn-Cr, Zn-P, Zn-Mn, thiab lwm yam yog tseem nyob rau hauv kev txhim kho thiab xeem daim ntawv thov. Zinc alloys muaj cov khoom tiv thaiv zoo, yog li lawv feem ntau hu ua high corrosion-resistant alloy coatings. Ntawm lawv, muaj ntau yam kev tshawb fawb thiab kev siv. Feem ntau siv cov alloys feem ntau yog zinc thiab hlau pawg hlau, uas yog zinc-nickel, zinc-cobalt thiab zinc-hlau. Cov qauv atomic thiab cov khoom ntawm cov hlau pawg hlau zoo sib xws, thiab lawv cov khoom sib xyaw ua ke hauv cov alloys nrog zinc kuj zoo sib xws. Los ntawm kev xav ntawm electrode muaj peev xwm, lub peev xwm ntawm cov pab pawg hlau hlau yog qhov zoo dua li cov zinc, tab sis thaum lub sij hawm sib koom ua ke, zinc yog yooj yim rau tso nyiaj ntau dua li cov hlau pawg hlau thiab yog qhov zoo dua tso. Qhov kev tso nyiaj zoo li no yog hu ua abnormal co-deposition. Qhov laj thawj yog vim li cas thaum zinc thiab hlau pawg hlau sib koom ua ke rau ntawm cathode nto, nrog nag lossis daus ntawm H2 ntawm cathode nto, pH nto nce, thiab zinc hydroxide colloidal zaj duab xis yog tsim rau ntawm cathode nto, ua rau hlau. pab pawg hlau ions ntawm qhov chaw cathode. Inhibition ua rau nws nyuaj rau tso nyiaj, yog li zinc nyiam precipitates ntawm cathode nto.
Nqus electroplating hluav taws xob cua sov raj silicon rectifier theem
(1) Nyob rau theem DC lub tshuab hluav taws xob, lub zog hluav taws xob no siv ntau lub zog, muaj kev ua haujlwm tsawg, thiab muaj suab nrov. tau raug tshem tawm.
(2) Silicon rectifier theem yog hloov khoom ntawm DC generator. Cov cuab yeej siv tau zoo heev, tab sis qhov ua tau zoo yog tsawg, qhov ntim loj, thiab kev tswj tsis tau yooj yim. Tseem muaj ntau lub lag luam siv cov khoom siv hluav taws xob electroplating no.
(3) Lub thyristor rectifier theem yog lub hauv paus fais fab mov los hloov lub silicon rectifier fais fab mov, uas muaj cov yam ntxwv ntawm high efficiency, me me, thiab yooj yim kev cai. Nrog rau cov cuab yeej tseem ceeb - kev loj hlob thiab kev loj hlob ntawm thyristor technology. Lub tshuab fais fab tau dhau los ua neeg paub tab thiab tau siv dav.
(4) Transistor hloov fais fab mov, uas yog, mem tes fais fab mov theem Pulse electroplating fais fab mov yog qhov zoo tshaj plaws electroplating fais fab mov hnub no, thiab nws cov tsos yog ib tug kiv puag ncig nyob rau hauv electroplating fais fab mov. Cov khoom siv fais fab no muaj qhov zoo ntawm qhov me me, kev ua haujlwm siab, kev ua haujlwm zoo dua thiab ruaj khov ripple coefficient. Thiab nws tsis yooj yim cuam tshuam los ntawm cov zis tam sim no thiab lwm yam. Pulse electroplating fais fab mov yog cov kev taw qhia ntawm txoj kev loj hlob thiab tam sim no tau pib siv hauv kev lag luam.
Nqus electroplating hluav taws xob cua sov tube txheej rwb thaiv tsev txoj kev
Xim-raws li insulating txheej feem ntau yog siv rau kev tiv thaiv rwb thaiv tsev thaum electroplating. Txoj kev tiv thaiv rwb thaiv tsev no yooj yim rau kev khiav lag luam thiab tuaj yeem siv rau qhov chaw nyuaj. Feem ntau siv insulating txheej muaj xws li perchloride anti-corrosion varnish, polyvinyl chloride insulating txheej, nitro kua nplaum, thiab lwm yam.
