Electroplating nyob rau hauv tsev - qhov tseem ceeb ntawm nws cov Cheebtsam

Tej zaum tsis muaj tsis muaj lub tsev neeg ua hauj lwm, uas yuav tsis yuav tsum tau mus them tus kheej manufactured khoom txheej ntawm zinc, chromium, tooj liab los yog npib tsib xee. Cov coatings yuav tsis tau tsuas yog ua hlau tej khoom zoo nkauj, tiam sis kuj ua rau nws tau los tiv thaiv lawv los ntawm ib puag ncig influences, raws li zoo raws li muab cov khoom rau hauv lub thaj chaw ntawm uas tsis tau yav tas los lawm xam qhovkev nyob rau ntawd.

Kev ua ub no, uas tso cai rau ib tug nyias txheej ntawm cov hlau rau ntawm qhov chaw ntawm cov khoom uas tso cai rau koj los mus tiv thaiv rau tom kawg ntawm corrosion thiab muab nws ib tug zoo nkauj nta hu ua electroplating thiab electroplating nyob rau hauv ib tug yooj yim hais lus. Electroplating nyob rau hauv tsev - ib tug heev heev tshwm sim nyob rau hauv peb lub teb chaws, vim hais tias muaj cov khoom rau electroplating hauv tsev los yog nyob rau hauv lub chav nres tsheb, txhua leej txhua tus muaj peev xwm nqa tawm nws tus kheej chrome plating, zinc plating, tooj liab plating, npib tsib xee plating ntawm tag nrho cov hlau cov khoom.

Ntawm cov hoob kawm, qhob electroplating presupposes lub hav zoov ntawm tej yam khoom, raws li zoo raws li kev txawj ntse nyob rau hauv lub teb ntawm electrochemical - tsis ua tsis muaj nws nyob rau hauv lub cover by means of electrolysis.

Ib yam ntawm cov loj Cheebtsam uas yuav tsum txhua tus yuav tau nyob rau hauv tsev electroplating yog galvanic da dej. Cov nram qab no yuav muab suav hais tias ib tug ntawm txoj kev ntawm lawv siv thiab ua. Txhua tus neeg uas tau txiav txim siab hais tias nws xav tau kev pab electroplating nyob rau hauv tsev, kev nyuaj siab nrog qhov teeb meem ntawm yuav ua li cas ua lub plating da dej los yog kho nws nyob rau hauv tej peev xwm.

Yog li ntawd, muaj ib tug pheej yig daws mus rau qhov teeb meem no. Muaj ntau cov tuam txhab muag tshuaj siv tshwj xeeb yas ntim. Txhua thawv obreshechena thiab Consolidated on pallets. Nws yog ib qhov muaj peev xwm yuav tau los siv ua lub hauv paus ntawm lub plating da dej.

Tom qab lub thawv tauj thiab ntsia yuav tsum tau ua tib zoo txiav tawm ntawm nws sab saum toj. Txiav ib feem ntawm qhov ntau pab - nws yuav tsum tau ua los ntawm lub da dej cover. Nrog lub xaus ntawm lub da dej yog ua li cas peb qhov uas yuav tsum tau ntsia anode rods. Ntawm cov hoob kawm, lub qhov yuav tsum tau nyob rau tib theem.

Lub hau ntawm lub plating da dej yuav tsum tau yuav tsum tau. Tom qab ntawd nws yog fastened mus rau lub tub los ntawm ib tug khawm, piv txwv li, piano. Yuav kom muab, uas yuav tsum tau muab ntawm lub hau thiab lub chav dej yog zoo meej roj hmab ntsaws ruaj ruaj rau lub tsheb rooj - lawv muag thaum twg nws pib kav thiab yuav tsum tau cog ib ncig ntawm lub perimeter ntawm lub da dej ntug. Tom qab kev txhim kho cov cover, nws yuav tsum haum snugly mus da dej ntug.

Yog li, ib tug da dej nrog ib tug flip hau, nyob rau hauv lem, muaj ib tug filling qhov, uas yog pom zoo kom siv mus txuas rau cua hose.

Nyob rau hauv yav tas los pom tau hais qhov nyob rau hauv cov laug cam tso rau hauv tooj liab pas nrig. Lawv yuav siv tau raws li cov tooj liab hlab haum txoj kab uas hla - 20mm. Nyob rau hauv cov ntaub ntawv uas, yog hais tias tus raj tsis muaj txaus rigidity, nws yog tso rau hauv lub steel bar. Qhov xaus ntawm lub hlab yuav tsum pluav, thiab ces tho qhov nyob rau hauv lawv rau tom qab txuas mus rau lawv ib tug rectifier.

Nyob rau hauv xaus, peb muaj ib qho piv txwv ntawm ib kauj ruam ntawm lub dab uas muaj peev xwm yuav nqa tawm nyob rau hauv lub saum toj no da dej - galvanizing. Cov kauj ruam yog sawv cev:

- degreasing khoom nyob rau hauv ib tug organic kuab;

- tshuaj degreasing nyob rau hauv alkali tshuaj;

- ntxuav cov khoom nyob rau hauv dej kub ;

- electrochemical degreasing nyob rau hauv alkaline tov;

- muab yaug nyob rau hauv dej kub;

- muab yaug hauv dej txias;

- kom los pickling;

- Ncaj qha galvanizing;

- Qhia meej ntxiv nta tshuaj ntawm nitric acid (yeem);

- passivation;

- muab yaug hauv dej txias;

- ntxuav nyob rau hauv dej sov, ib tug kub ntawm txog 40 ° C, tiam sis tsis muaj ntau;

- kom qhuav ntawm cov khoom tiav.

Peb cia siab tias koj electroplating nyob rau hauv lub tsev yuav qhib li tshiab tau!
