Cov khoom lag luam Chrome tau nrov heev niaj hnub no. Thiab qhov taw tes tsis yog tsuas yog nyob rau hauv lawv cov tsos zoo nkauj, tab sis kuj yog lawv cov neeg siv khoom zoo. Cov txheej txheem chromium tiv thaiv cov khoom los ntawm xeb thiab kev puas tsuaj rau cov tshuab, ua ib daim pam thermal, thiab lwm yam. Siv yas rau cov thwmsim.
Cov Lus Qhia

Txhawm rau nqa tawm chromium plating ntawm yas, koj tuaj yeem ua tiav qhov kev txhim kho me me galvanic installation, uas tsis tas yuav tsum muab cov khoom tso rau hauv da dej. Lub installation suav nrog qhov hluav taws xob txo qhov hloov pauv ntawm 12 V thiab qhov tam sim no ntawm 0, 8 thiab 1 A, txhuam nrog cov txhuam tshwj xeeb (rooj plaub yog ua los ntawm cov iav iav nrog lub taub 20-25 hli - cov hluav taws xob tau muab nchuav rau nws). Tsis tas li, hloov chaw hloov hluav taws xob, roj teeb nrog txhua tus xov hlau siv. Cov txhuam hniav txhuam yuav tsum muab qhwv nrog cov hlau txhuas hlau (yog tias muaj tsawg, nws tuaj yeem hloov nrog tooj liab). Daim diode ntawm DZOZ - DZO5 hom yuav tsum muab ntsia rau ntawm lub cev txhuam. Txuas qhov txuas ntawm cov diode mus rau ib qho ntawm cov kab hluav taws xob ntawm lub tshuab hloov hluav taws xob ntawm qis qis ntawm cov kab sib hloov, cathode, kho nws hauv lub clamp, yuav tsum txuas nrog rau feem kom tau coated. Thaum siv roj teeb, lub diode tsis siv.

Qhov uas yuav ua tiav yuav tsum muab cov roj, xeb thiab lwm yam av ntxuav kom huv. Tom qab ntawd koj yuav tsum tau ua cov ntu hauv kev tov, qhov muaj pes tsawg leeg uas suav nrog 100-150 g ntawm sodium, 3-5 g ntawm silicate kua nplaum, zoo li 35-50 g ntawm dej qab zib tshauv ib 1 liter dej. Cov tshuaj lim dej yuav tsum tau rhaub kom kub txog 80-100 degrees C, nyob ntawm qhov sib kis ntawm ib feem thiab khaws cia rau hauv nws li 15 feeb txog 1 teev. Electroplating yuav nyob ntawm seb qhov saum npoo ntawm ib feem yog txawm thiab huv. Cov txheej txheem ua ntej tau txuas nrog lub tshuab hloov hluav taws xob, qhov yuav tsum tau ntawm cov roj electrolyte tau muab tso rau hauv txhuam thiab lub zog tau muab rau. Thaum ua ntawv thov ib txheej dhau ntawm cov hlau uas seem los ntawm cov electrolyte mus rau saum npoo ntawm ib feem, maj mam txav cov txhuam hauv qhov nce thiab nqis. Yuav kom ua tiav cov txheej yuav tsum tau ua kom tuab tuab, cov lus hla dhau ib qho chaw sib txawv ntawm 20 txog 30 zaug. Rov ntim koj cov txhuam nrog electrolyte thaum nws tas.

Tom qab ua tiav, cov ntu yuav tsum tau yaug hauv cov dej khib nyiab, tom qab ntawd polishing nrog ib qho ntawm cov khoom. Qhov kev daws teeb meem saum toj no yuav tsum tau ua kom zoo nrog kev saib xyuas kom tsis txhob txais cov roj hlawv roj thiab lom. Nws yuav muaj kev nyab xeeb tshaj yog khaws lub lauj kaub tais diav rau hauv lub khob ntim nrog qhov tsaus ntuj thiab cork muaj zog.

Tsis tas li ntawd coj mus rau hauv tus account qhov tseeb tias tsis yog txhua txhua lub tsho tiv no tuaj yeem tiv thaiv nrog cov hlau sib txawv. Piv txwv li, txhawm rau tsim cov xim nickel plating rau ntawm cov hlau, nws yog thawj kho nrog txheej txheej ntawm tooj liab, thaum chrome saum npoo cuam tshuam zoo nrog nickel-plated nto.
