Nqus chrome plating seals residues nyob rau hauv lub substrate los xyuas kom meej txheej zoo

 

Cov plasticizer residue, corrosive gas residue, pwm tso tus neeg sawv cev lubricant thiab lwm cov roj molecule residues nyob rau hauv lub substrate yog kaw los ntawm UV txheej los tiv thaiv cov volatile impurities los ntawm overflowing nyob rau hauv lub substrate thaum lub sij hawm lub tshuab nqus tsev txheej los yog thaum lub sij hawm siv lub workpiece, cuam tshuam rau cov txheej txheem zoo. .

 

Kev tso tawm ntawm cov impurities nyob rau hauv lub substrate yuav ua rau cov aluminized zaj duab xis rau glow, discolor, oxidize, blacken, thiab lwm yam, uas yuav cuam tshuam rau cov hlau zoo nkauj thiab zoo li lub tshuab nqus tsev electroplating.

Nqus chrome plating tsub kom qhov adhesion ntawm txheej rau saum npoo ntawm cov yas substrate

 

 

 

Lub reactive diluent nyob rau hauv lub primer UV txheej muaj ib tug muaj zog erosive muaj peev xwm rau cov yas substrate. Cov reactive diluent me ntsis swells los yog softens cov yas substrate, yog li ntawd tom qab lub txheej yog kho, ib tug interpenetration yog tsim ntawm primer UV thiab substrate interface. network, uas tuaj yeem txhim kho qhov adhesion ntawm tag nrho cov txheej txheej.

 

Yog tias lub tshuab nqus tsev tau ua ncaj qha rau ntawm qhov chaw ntawm cov yas substrate yam tsis muaj UV txau ntawm primer, qhov tsis muaj zog ntawm cov hlau txheej txheej ntawm cov yas substrate yuav ua rau tsis zoo adhesion ntawm txheej txheej thiab cov yas substrate.

Nqus chroming pickling kev kho mob

 

Thaum lub sij hawm electroplating, ib tug nruam crystalline qauv tsis tuaj yeem tsim los ntawm lub hauv paus stainless hlau npo thiab txheej ntawm stainless hlau screen vim muaj cov tsis-stainless hlau interlayers, uas ua rau muaj kev sib raug zoo tsis zoo xws li blistering los yog tev ntawm txheej. Yog li ntawd, cov txheej txheem metamorphic xws li nplai, xeb thiab oxide yuav tsum tau muab tshem tawm kom huv si. Txawm hais tias txheej txheej txheej txheej, txheej txheej plating tuaj yeem ua ke nrog nws, yog li nws tsis tas yuav raug tshem tawm los ntawm etching, feem ntau tsuas yog yuav tsum tau kho cov pickling.

 

Thaum cov khoom siv tshuaj ntsuam stainless hlau khaws cia hauv huab cua, txawm tias lub sijhawm luv luv, cov khoom xws li plua plav lossis roj uas tau tawg hauv huab cua yuav ua raws li qhov chaw los tsim cov av txheej.

 

Cov av tuaj yeem muab faib ua ob pawg:

 

Ib qho yog inorganic av, nrog rau cov khoom abrasive, xuab zeb thiab plua plav hauv huab cua thiab stainless hlau tshuaj ntsuam hmoov. Lwm hom yog cov organic av, nrog rau cov tsiaj thiab zaub roj, cov roj ntxhia, cov roj sib xyaw, thermal adhesions thiab polishing paste residue. Thaum lub sij hawm electroplating, txawm tias me me ntawm cov av txheej tseem nyob ntawm qhov chaw, uas yuav ua rau muaj qhov tsis xws luag xws li kev sib txuas tsis muaj zog thiab tev ntawm txheej plating, yog li cov av txheej yuav tsum tau muab tshem tawm. Cov txheej txheem no hu ua degreasing.

 

Feem ntau, nws yog ib qho tsim nyog yuav tsum tsis txhob ntxuav lub ntsej muag thaum lub sijhawm tsim khoom, thiab tib lub sijhawm, ua tib zoo saib xyuas kom muaj huab cua zoo thaum lub sijhawm tsim khoom, thiab zam titanium plating hauv qee qhov chaw plua plav thiab plua plav.
