Lub tshuab nqus tsev electroplating hluav taws xob cua sov raj muaj kev ua tau zoo dua li tib yam

Lub hauv paus ntsiab lus ntawm kev ua yeeb yaj kiab ntawm galvanized chromium-free passivation sealer yog qhov tseem ceeb sib txawv ntawm chromium ntsev passivation thiab sealing, thiab nws kuj txawv ntawm polymer resin sealing. Tom qab cov dej noo ntawm cov khoom galvanized volatilizes, qee cov organic tshuaj tebchaw nrog zinc txheej tshuaj, thiab qhov kub thiab txias, qhov zoo dua cov tshuaj tiv thaiv. Cov tshuaj uas tsis koom nrog cov tshuaj tiv thaiv yuav tsim ib txheej hydrophobic anti-xeb zaj duab xis. Cov txheej txheem tiv thaiv corrosion ntawm chromium passivation sealer yog tsim los ntawm cov txheej txheem passivation, txheej tiv thaiv xeb thiab txheej hydrophobic, yog li nws muaj zog corrosion kuj thiab kho muaj peev xwm.

Piv nrog rau lwm cov chrome-free passivation agents, BW-525 yog nruab nrab, cov kua yog ruaj khov, noj tsawg dua, thiab corrosion kuj yog qhov zoo dua. Tom qab kev kho mob, daim ntawv galvanized tsis xav tau kev kho mob (degreasing, phosphating, passivation, thiab lwm yam) ua ntej txau thiab dov, thiab muaj cov adhesion zoo heev, cuam tshuam tsis kam thiab khoov tsis kam, txuag nyiaj ntau ntawm cov khoom. Qhov no yog ib yam khoom uas tsis muaj lwm yam passivation sealer muaj. Thiab kom tswj tau tus thawj luster ntawm galvanized txheej, thiab muab nws nto ib co lubrication thiab khawb kuj.

Kev ceev faj rau Electroplating ua ntawm Nqus Electroplating Hluav Taws Kub Kub Tube Pwm

Vim yog cov thev naus laus zis tshiab thiab kev txhim kho ntawm aluminium formwork, tshwj xeeb tshaj yog rau kev tsim cov pwm txhaj tshuaj, txhuas pwm kuj tau siv ntau hauv tshuab pwm, RIM pwm, roj hmab pwm, pwm pwm pwm, thiab RTM pwm. Txawm hais tias nws yuav tsis haum rau txhua qhov chaw thov, qhov tseeb, nws siv tau ntau thiab ntau dua. Txhua leej txhua tus xav kom muaj peev xwm ua kom ntev lub neej ntawm lawv cov pwm, xws li ua pwm los ntawm cov cuab yeej siv ib txwm siv nrog cov tawv chrome lossis npib tsib xee hlau plating, lossis ntau qhov tshwj xeeb engineering txheej, uas tiv thaiv lawv qhov chaw los ntawm galling lossis galling. Corrosion, prompting nws zoo demoulding. Txij thaum ntawd los, nyob rau hauv kev nrhiav tib lub hom phiaj, aluminium moulds tau txais kev pom zoo thiab pom muaj kev daws teeb meem.

Txhawm rau kom muaj peev xwm tsim cov khoom zoo nkauj los ntawm kev txhaj tshuaj molding, ntxiv rau txuas ntxiv lub neej kev pab cuam ntawm pwm, cov chaw tsim khoom kuj xav kom lub ntsej muag ntawm txhuas pwm kom muaj qee qhov gloss, yog li nws raug nquahu kom siv electroless. nickel spray txheej txheem, vim tias txoj kev no yuav pab txuas ntxiv lub neej ntawm cov pwm nto tiav, ua rau nws yooj yim los tsim cov khoom zoo nkauj.

Vim yog cov ntaub ntawv mos ntawm aluminium, yog tias tsis siv cov txheej txheej saum npoo, nws yooj yim hnav los ntawm cov yas, ua kom nws qhov kev puas tsuaj thiab hloov qhov gloss ntawm kev txhaj tshuaj molded. Electroless npib tsib xee txheej tuaj yeem ua rau pwm saum npoo los ntawm 50RC, uas txaus los tiv thaiv thiab ua kom ntev lub ntsej muag thiab cov qauv ntawm pwm nto. Electroless npib tsib xee txheej tuaj yeem ua tiav qhov ua tiav zoo dua li cov txhuas nws tus kheej, tab sis nws yuav tsum tau muab sau tseg tias qee qhov kev npaj saum npoo yuav tsum tau ua ntej ua ntej pwm tuaj yeem electroplated. Piv txwv li, txhawm rau ua kom nws ua tiav qib qib qib zoo, nws raug nquahu kom ua ntej tshuab qhov chaw ntawm txhuas pwm mus rau SPIA-3 qib tiav, thiab tom qab ntawd siv 0. 0003 ~ 0.0005 high-phosphorus electroless npib tsib xee txheej ua ntej nws ntxiv polished, coj nws mus rau lub pob zeb diamond-zoo tiav qib.
