Qhov sib txawv tseem ceeb ntawm txheej txheej thiab plating yog tias txheej tuaj yeem ua tiav ntawm ob qho tib si conductive thiab tsis yog-conductive, whereas plating tuaj yeem ua rau ntawm cov khoom siv hluav taws xob.
Txheej thiab plating yog cov txheej txheem siv los npog qhov chaw ntawm cov khoom nrog cov khoom. Peb hu cov khoom no hu ua "substrate". Lub hom phiaj ntawm qhov npog no tuaj yeem ua kom zoo nkauj, ua haujlwm lossis ob qho tib si. Piv txwv li, kev npog saum npoo yog qee zaum tseem ceeb rau qhov zoo ntawm cov khoom thiab kuj tseem tuaj yeem tiv thaiv qhov chaw ntawm cov khoom los ntawm corrosion.
Txheej yog dab tsi?
Txheej yog npog qhov chaw ntawm ib qho khoom. Cov khoom uas tau coated feem ntau yog hu ua substrate. Txheej yog qhov tseem ceeb rau kev kho kom zoo nkauj, lub hom phiaj ua haujlwm lossis rau ob qho tib si. Piv txwv li, cov xim thiab lacquers yog ib qho tseem ceeb hauv kev tiv thaiv qhov chaw ntawm lub substrate thiab tseem siv rau kev kho kom zoo nkauj. Cov khoom ua haujlwm ntawm txheej muaj xws li adhesion, wettability, corrosion resistance, hnav tsis kam, thiab lwm yam. Txheej tuaj yeem npog tag nrho cov khoom lossis tsuas yog qee qhov ntawm cov khoom.
Daim duab 01: Painting fwj rau Decorative Purposes
Ib qhov tseeb ntawm txheej txheej yog daim ntawv thov txheej txheej ntawm kev tswj cov tuab. Feem ntau, peb tsuas yog siv cov ntawv nyias nyias ntawm cov txheej xws li ntawv, ntaub, zaj duab xis, ntawv ci, thiab daim ntawv Tshuag. Tsis tas li ntawd, cov khoom siv txheej tuaj yeem yog kua, khoom, lossis cov khoom siv gaseous.
Muaj ob txoj hauv kev puas tsuaj thiab tsis muaj kev puas tsuaj uas yog qhov tseem ceeb hauv kev tshuaj xyuas txheej txheej. Piv txwv li, qhov kev tsom xam ntawm qhov ntsuas ntawm qhov sib txuas ntawm cov txheej txheem thiab cov txheej txheem yog ib txoj kev puas tsuaj, thaum ntsuas qhov tuab ntawm ultrasonic yog txoj kev tsis muaj kev puas tsuaj.
Platting yog dab tsi?
Plating yog hom txheej txheej uas cov hlau tso rau ntawm qhov chaw ua haujlwm. Cov txheej txheem no tau siv los ntawm tib neeg txij li lub sijhawm qub, thiab nws yog qhov tseem ceeb hauv cov cuab yeej siv niaj hnub no thiab. Lub hom phiaj ntawm plating tuaj yeem ua kom zoo nkauj, corrosion inhibition, txhim kho solderability, hardening, txo kev sib txhuam, hloov conductivity, txhim kho IR reflectivity, hluav taws xob shielding, thiab lwm yam. Piv txwv li, peb siv plating hauv kev lag luam jewelery kom tau ib qho kub lossis nyiaj tiav..
Daim duab 02: Tooj Electroplating
Muaj ntau txoj kev plating, xws li electroplating, vapor deposition, sputter deposition, thiab lwm yam. Electroplating txoj kev siv ib tug ionic hlau uas yog muab nrog electrons los ua ib tug non-ionic txheej ntawm ib tug substrate. Nyob rau hauv txoj kev electroless plating, muaj ob peb tib lub sij hawm cov tshuaj tiv thaiv nyob rau hauv ib tug aqueous tov yam tsis tau siv cov khoom siv hluav taws xob sab nraud. Ntxiv rau qhov ntawd, muaj qee cov txheej txheem plating tshwj xeeb uas muaj npe raws li cov hlau uas siv los npog; Piv txwv li, kub plating, nyiaj plating, chrome plating, zinc plating, rhodium plating, tin plating, thiab lwm yam.
Qhov txawv ntawm Txheej thiab Plating yog dab tsi?
Txheej thiab plating yog cov txheej txheem ntawm kev npog saum npoo. Qhov sib txawv tseem ceeb ntawm txheej txheej thiab plating yog tias txheej tuaj yeem ua tiav ntawm ob qho tib si conductive thiab tsis-conductive nto, hos plating tuaj yeem ua rau ntawm cov khoom siv hluav taws xob. Tsis tas li ntawd, txheej txheej tuaj yeem ua tiav los ntawm kev siv cov txheej txheem yooj yim xws li txhuam los yog siv cov tshuab kim kim thaum plating nrog rau daim ntawv thov ntawm cov hlau rau ntawm qhov chaw uas siv cov hluav taws xob sab nraud lossis siv qee qhov kev cuam tshuam ib txhij.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm txheej txheej thiab plating.
Summary – Txheej vs Plating
Txheej thiab plating yog cov txheej txheem ntawm kev npog saum npoo. Qhov sib txawv tseem ceeb ntawm txheej thiab plating yog tias txheej tuaj yeem ua tiav ntawm ob qho tib si conductive thiab non-conductive nto, whereas plating tuaj yeem ua rau ntawm cov khoom siv hluav taws xob.
