Thaum nws los txog rau electroplating, peb yuav tsum xub nkag siab tias nws yog dab tsi tiag tiag. Hais yooj yim, electroplating yog cov txheej txheem ntawm kev siv lub hauv paus ntsiab lus ntawm electrolysis los tso ib txheej nyias nyias ntawm lwm cov hlau lossis cov alloys rau ntawm qhov chaw hlau.
Qhov no tsis yog rau qhov zoo nkauj xwb, tab sis qhov tseem ceeb tshaj, nws tuaj yeem tiv thaiv kev oxidation thiab xeb, thaum txhim kho qhov hnav tsis kam, conductivity, thiab corrosion tsis kam ntawm qhov chaw. Tau kawg, qhov zoo nkauj kuj tuaj yeem txhim kho tau.
Muaj ntau hom electroplating, suav nrog tooj liab plating, kub plating, nyiaj plating, chrome plating, nickel plating, thiab zinc plating. Hauv kev lag luam tsim khoom, zinc plating, nickel plating, thiab chrome plating yog siv dav heev. Qhov txawv ntawm peb yam no yog dab tsi? Cia peb saib ib qho zuj zus.
Kev plating zinc
Zinc plating yog txheej txheem ntawm kev txheej ib txheej zinc rau ntawm qhov chaw ntawm cov hlau lossis lwm yam khoom siv, feem ntau yog rau kev tiv thaiv xeb thiab lub hom phiaj zoo nkauj.
Cov yam ntxwv yog tus nqi qis, tiv taus corrosion zoo, thiab xim dawb nyiaj.
Feem ntau siv rau cov khoom uas pheej yig thiab tiv taus xeb xws li cov ntsia hlau, cov khoom siv hluav taws xob, thiab cov khoom lag luam.
Nickel plating
Nickel plating yog txheej txheem ntawm kev tso ib txheej ntawm nickel rau ntawm qhov chaw los ntawm electrolysis lossis cov txheej txheem tshuaj lom neeg.
Nws cov yam ntxwv yog tias nws muaj qhov zoo nkauj, tuaj yeem siv rau kev kho kom zoo nkauj, kev ua haujlwm yog qhov nyuaj me ntsis, tus nqi kuj tseem siab, thiab xim yog nyiaj dawb nrog me ntsis daj.
Koj yuav pom nws ntawm cov taub hau teeb txuag hluav taws xob, cov npib, thiab qee cov khoom siv kho vajtse.
Chrome plating
Chrome plating yog txheej txheem ntawm kev tso ib txheej chromium rau ntawm qhov chaw. Chrome nws tus kheej yog hlau dawb ci nrog me ntsis xiav.
Chrome plating feem ntau yog muab faib ua ob hom: ib qho yog kho kom zoo nkauj, nrog rau qhov zoo nkauj, hnav tsis kam, thiab tiv thaiv xeb me ntsis phem dua li zinc plating tab sis zoo dua li oxidation ib txwm muaj; Qhov tod tes yog ua haujlwm, nrog lub hom phiaj ntawm kev ua kom qhov nyuaj thiab hnav tsis kam ntawm cov khoom.
Cov khoom dai ci ntsa iab ntawm cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob, nrog rau cov cuab yeej thiab cov kais dej, feem ntau siv chrome plating.
Qhov sib txawv tseem ceeb ntawm peb yam no
Chrome plating feem ntau yog siv los ua kom tawv, zoo nkauj, thiab tiv thaiv xeb. Cov khoom siv tshuaj lom neeg ntawm cov txheej chromium ruaj khov thiab tsis ua rau alkali, nitric acid, thiab feem ntau cov organic acids, tab sis lawv rhiab rau hydrochloric acid thiab kub sulfuric acid. Nws tsis hloov xim, muaj peev xwm cuam tshuam ntev, thiab muaj zog dua li nyiaj thiab nickel. Cov txheej txheem feem ntau yog electroplating.
Kev plating nickel tsom mus rau kev tiv thaiv kev hnav, kev tiv thaiv corrosion, thiab kev tiv thaiv xeb, thiab feem ntau cov txheej txheem yog nyias. Muaj ob hom txheej txheem: electroplating thiab chemistry.
Yog li ntawd, yog tias cov peev nyiaj tsawg, kev xaiv zinc plating yog qhov kev xaiv zoo; Yog tias koj nrhiav kev ua tau zoo dua thiab zoo nkauj dua, koj yuav tsum xav txog nickel plating lossis chrome plating. Ib yam li ntawd, dai plating feem ntau kim dua li dov plating hauv cov txheej txheem.
