Hauv kev lag luam niaj hnub, cov tshuaj tiv thaiv saum npoo av ua lub luag haujlwm tseem ceeb. Lawv tsis tuaj yeem txhim kho kom zoo nkauj ntawm cov ntaub ntawv, tab sis kuj tseem txhim kho lub corrosion tsis kam, coj kev tawm tsam, conductivity thiab lwm yam tshwj xeeb ntawm cov ntaub ntawv. Chrome plating, Nickel plating thiab Zinc plating yog peb qhov uas muaj nws tus kheej tshwj xeeb zoo thiab cov chaw thov. Kab lus no yuav tshawb txog qhov sib txawv ntawm peb lub ntsiab cai no, suav nrog lawv cov qauv, thov teb thiab lawv cov txiaj ntsig thiab lawv txoj kev zoo thiab qhov tsis zoo.
Chrome plating
1. Cov Ntsiab Cai Txheej Txheem
Chrome plating yog txheej txheem ntawm kev tso nyiaj txheej txheej ntawm chromium ntawm lub hauv paus ntawm cov hlau los ntawm electrolysis. Qhov tsim ntawm cov txheej chromium feem ntau yog nyob ntawm cov chromium chromium raug rho tawm kom txo tau cov hluav taws xob tam sim no thiab muab tso rau ntawm catherohode (piv txwv li cov workpiece). Lub Chrome plating txheej txheem feem ntau muab faib ua ob pawg: zoo nkauj chrome plating thiab ua haujlwm chrome plating. The former focuses on the brightness and uniformity of the appearance, while the latter emphasizes wear resistance and corrosion resistance.
2. Kev ua txuj ci
• Muaj Hardness Siab: Lub Chrome plating muaj qhov nyuaj heev, thib ob nkaus xwb rau pob zeb diamond, uas tau txhim kho cov coj tsis kam ntawm cov workpiece.
• Cov tshuaj corrosion zoo: Chromium Plating Cov Khoom Taw Qhia Corrosion Defosion thiab yaig los ntawm qee cov tshuaj lom neeg.
• Gloss zoo: Hniav chrome plating tuaj yeem muab cov ua haujlwm daim iav-zoo li ci thiab txhim kho cov khoom qib.
3. Daim ntawv thov teb
Chromium plating yog dav siv hauv cov tsheb xws li tsheb, thiab lwm yam, thiab lwm yam.
4. Qhov zoo thiab qhov tsis zoo
Qhov zoo dua nyob rau hauv nws heev heev hardness thiab zoo corrosion tsis kam, uas cuam tshuam ntau yam kev pabcuam lub neej ntawm workpiece. Txawm li cas los xij, Chrome plating plating plating txheej txheem muaj qee cov pa phem rau ib puag ncig, thiab tus nqi yog qhov tseem ceeb, thiab cov qauv ntawm cov khoom lag luam yog qhov yuav tsum tau ua.
Nickel Plating
1. Cov Ntsiab Cai Txheej Txheem
Nickel plating yog cov txheej txheem ntawm kev tso ib txheej ntawm npib tsib xee nyob rau saum npoo ntawm cov hlau los ntawm electrolysis. Lub npib tsib xee yog feem ntau yog ob npib sulfate lossis Nickel chloride system, thiab tus nqi tsim nyog tau ntxiv los tswj cov kev ua tau zoo thiab pom ntawm txheej. Lub Nickel plating txheej txheem tuaj yeem faib ua ci nickel plating, semi-kaj nickel plating, npib tsib xee thiab lwm hom kom tau raws li cov ntawv thov sib txawv.
2. Kev ua txuj ci
• Hnav zoo tiv thaiv: Nickel plating muaj siab hardness thiab hnav tsis kam, thiab yog qhov haum rau qee lub sijhawm uas yuav tsum tau tiv thaiv kev hnav.
• Muaj zog corrosion: Nickel plating qhia qhov ruaj khov zoo nyob rau hauv ntau yam ntawm cov tub ceev xwm corrosive, tshwj xeeb tshaj yog kev ua tau zoo tshaj plaws tiv thaiv kev ua kom huv.
• Kev ua tau zoo thiab Weldability plating muaj kev ua haujlwm zoo thiab yog ib qho yooj yim rau Weld, haum rau cov hluav taws xob thiab cov hluav taws xob sib txuas.
3. Daim ntawv thov teb
Nickel plating yog dav siv nyob rau hauv electronics, tsheb, aerospace, cov khoom siv tshuaj, khoom siv khomob. Xws li pins ntawm cov hluav taws xob hluav taws xob, qhov chaw ntawm cov tsheb uas yog cov txheej txheem ntawm Aerospacace, corrosion-resistant txheej ntawm cov khoom siv tshuaj lom neeg, thiab cov khoom ntoo nteg ntawm cov khoom siv kho mob.
4. Qhov zoo thiab qhov tsis zoo
Qhov zoo ntawm Nickel plating yog nws cov kev coj zoo tsis kam, corrosion tsis kam thiab ua kev ua tau zoo. Txawm li cas los xij, npib tsib xee plating plating plating kuj tseem muaj cov teeb meem paputal ib puag ncig, thiab kev sib txuam ntawm lub plating yog qhov nyuaj rau kev tswj hwm, uas yuav tsum muaj cov txheej txheem tswj nruj.
Galvanizing
1. Cov Ntsiab Cai Txheej Txheem
Galvanizing yog cov txheej txheem ntawm kev tso ib txheej ntawm zinc nyob rau saum npoo ntawm cov hlau los ntawm electrolysis lossis kub dip plating. Electrolytic galvanizing yog cov txheej txheem ntawm txo zincing zincing zinc thiab tso lawv tso rau ntawm qhov kev txiav txim ntawm hluav taws xob tam sim no; Kub-DIP galvanizing yog cov txheej txheem ntawm immersing lub workpiece nyob rau hauv molten zinc kua kom tsim ib qho txheej txheem alloy ntawm zinc thiab cov hlau sib txuas.
2. Kev ua txuj ci
• Kev ua tau zoo heev corrosion: zinc txheej tuaj yeem tsim cov yeeb yaj kiab zinc nyob rau hauv ib puag ncig corrosive, muaj txiaj ntsig zoo ntxiv yaig los ntawm txoj kev xeb.
• Tus nqi tsawg: piv nrog Chrome plating thiab npib tsib xee, cov txheej txheem yooj yim, ua kom yooj yim kom ua tiav cov khoom tsim loj.
• Zoo adhesion thiab cov txheej txheem: cov txheej txheej zinc yog ruaj khov rau lub hauv paus hlau thiab yooj yim rau cov txheej txheem thiab rub rau tom qab.
3. Daim ntawv thov teb
Galvanizing yog dav siv hauv kev tsim kho, kev thauj mus los, hluav taws xob, kev sib txuas lus thiab lwm thaj teb. Xws li cov kav dej steel, cov hlau nplaum, bolts, thiab lwm yam.
4. Qhov zoo thiab qhov tsis zoo
Qhov zoo ntawm Galvanizing yog nws tus nqi qis, kev tiv thaiv zoo heev corrosion thiab cov txheej txheem zoo. Txawm li cas los xij, lub hardness thiab hnav tsis kam ntawm zinc txheej yog cov tsis tshua muaj, thiab nws tsis haum rau qee lub sijhawm uas yuav tsum tau tiv thaiv cov neeg kho tshuab siab. Ib qho ntxiv, cov haus luam yeeb zinc thiab zinc slag tuaj yeem tsim thaum kub-dip Galvanizing, uas muaj qee qhov cuam tshuam rau ib puag ncig.
Lub ntsiab
Chrome plating, Nickel plating thiab Zinc plating yog peb qhov tseem ceeb saum npoo kev kho mob thev naus laus zis, txhua tus muaj cov yam ntxwv ua tau zoo thiab cov ntawv thov cov ntawv thov. Chrome plating yog paub rau nws cov hardness siab thiab zoo corrosion thiab zoo corrosion tsis kam, thiab yog haum rau lub sijhawm uas yuav tsum tau wroungical cov neeg kho tshuab hnav thiab kev ua kom haum; Nickel plating yog cov hnav tsis kam, corrosion tsis kam thiab ua cov khoom siv tau, thiab yog cov tsheb, aerospace thiab lwm thaj chaw; Zinc plating tau dhau los ua qhov kev xaiv thawj zaug hauv kev tsim kho, tsheb thauj mus los thiab lwm liaj thaj teb nrog nws tus nqi qis, kev ua tau zoo corrosion thiab kev ua haujlwm zoo.
Thaum xaiv cov thev naus laus zis deg, kev txiav txim siab zoo yuav tsum tau muab rau qhov kev siv tshwj xeeb thiab kev ua tau zoo ntawm cov haujlwm. Tib lub sijhawm, cov xim yuav tsum tau them rau cov teeb meem kev tiv thaiv ib puag ncig thiab kev txhim kho kev nyab xeeb thiab cov peev txheej hauv cov txheej txheem ntau lawm. Yav tom ntej, nrog kev nce qib nro ntawm kev tiv thaiv kev tiv thaiv thiab zinc plating ua ke nrog kev tsim kho kom zoo dua thiab cov kev kho kom zoo dua qub. (来源: 光机之家)
