electroplating yog dab tsi?
Electroplating yog txheej txheem ntawm kev siv lub hauv paus ntsiab lus ntawm electrolysis los tso ib txheej nyias ntawm lwm cov hlau los yog alloys ntawm qee qhov chaw hlau. Nws yog cov txheej txheem uas siv electrolysis los txuas cov yeeb yaj kiab hlau rau saum npoo ntawm cov hlau lossis lwm yam khoom siv, yog li tiv thaiv cov hlau oxidation (xws li xeb), txhim kho hnav tsis kam, conductivity, reflectivity, corrosion resistance (xws li tooj liab sulfate), thiab txhim khu kev zoo nkauj.
Electroplating tau muab faib ua cov txheej txheem tshwj xeeb xws li tooj liab plating, kub plating, nyiaj plating, chromium plating, npib tsib xee plating, thiab zinc plating. Hauv kev lag luam tsim, zinc plating, npib tsib xee plating, thiab chromium plating tshwj xeeb yog siv dav. Qhov txawv ntawm peb qhov no yog dab tsi?
01- Galvanization
Lus Txhais: Zinc plating yog hais txog cov txheej txheem kho saum npoo uas cuam tshuam nrog txheej txheej zinc ntawm cov hlau, hlau, lossis lwm yam khoom siv rau kev zoo nkauj thiab tiv thaiv xeb.
Nta: Tus nqi qis, nruab nrab corrosion kuj, nyiaj dawb xim.
Daim ntawv thov: Screws, Circuit Court breakers, industrial khoom, thiab lwm yam.
02- Nickel plating
Lus Txhais: Cov txheej txheem ntawm plating ib txheej ntawm npib tsib xee rau ntawm ib lub hlau los yog tej yam tsis yog hlau los ntawm electrolysis los yog chemical txoj kev hu ua npib tsib xee plating.
Nta: Zoo nkauj, tuaj yeem siv rau kev kho kom zoo nkauj, tus nqi siab, me ntsis kev siv tes ua haujlwm, thiab xim yog nyiaj dawb thiab daj.
Daim ntawv thov: Lub zog txuag lub teeb tuav, npib, khoom kho vajtse, thiab lwm yam.
03- Chromium plating
Lus Txhais: Chromium yog ib lub ci dawb hlau nrog xim xiav me ntsis. Cov txheej txheem ntawm plating txheej ntawm chromium rau ntawm cov hlau lossis qee yam tsis yog hlau los ntawm electrolysis lossis tshuaj siv tshuaj hu ua chromium plating.
Nta: Muaj ob hom chrome plating. Thawj yog rau kev kho kom zoo nkauj, nrog lub ntsej muag ci thiab zoo hnav tsis kam. Nws muaj peev xwm tiv thaiv xeb tsis zoo li zinc plating, tab sis zoo dua oxidation; Qhov thib ob txoj kev yog ua kom lub hardness thiab hnav tsis kam ntawm cov hlau qhov chaw, uas yog lub functionality ntawm qhov chaw.
Daim ntawv thov: Ci ntsa iab qhov chaw, cov cuab yeej, faucets, thiab lwm yam ntawm cov khoom siv hauv tsev, hluav taws xob thiab lwm yam khoom siv.
Nthuav kev paub:
1. Electroplating ntau lawm yog tsim los ntawm cov hlau hnyav hnyav hauv cov dej phwj tuaj thiab cov dej phwj tuaj. Lub teb chaws tau nruj me ntsis tswj kev nthuav dav ntawm kev lag luam electroplating thiab tau txo nws lub xyoo los ntawm xyoo.
Hauv Suav teb, cov txheej txheem electroplating feem ntau suav nrog galvanization, tooj liab plating, npib tsib xee plating, thiab chromium plating, nrog galvanization accounting rau 50% thiab tooj liab plating, chromium plating, thiab npib tsib xee plating accounting rau 30%.
Yog tias lub hom phiaj yog los tiv thaiv xeb, galvanizing lossis cadmium plating tuaj yeem siv tau; Yog tias kev tsom mus rau kev tiv thaiv kev hnav, nickel lossis chromium plating yog qhov kev xaiv zoo tshaj plaws.
