Hauv kev tsim khoom lag luam. Cov khoom siv Casters, ua ib feem tseem ceeb ntawm nws cov thev naus laus zis kho qhov chaw yog qhov tseem ceeb los txhim kho qhov zoo nkauj, kev ruaj khov thiab kev tiv thaiv corrosion ntawm cov khoom. Galvanizing ua ib qho kev kho qhov chaw. Siv dav hauv kev kho qhov chaw ntawm cov hlau caster. Tsab xov xwm no yuav piav qhia txog ntau txoj hauv kev ntawm galvanizing casters, suav nrog cyanide galvanizing, zincate galvanizing, chloride galvanizing, thiab sulfate galvanizing. Tsim los muab cov neeg nyeem nrog kev siv tshuab ua tiav.
1. Kev kho mob Cyanide galvanization
Cyanide galvanizing, vim nws lub zog dispersing siab thiab zoo plating zoo. Ib lub sijhawm nws tau nyob hauv txoj haujlwm tseem ceeb hauv kev lag luam electroplating. Txawm li cas los xij. Vim yog qhov xwm txheej lom ntawm cyanide nws tus kheej thiab qhov kev hem thawj rau ib puag ncig. Nws siv yog txwv tsis pub. Txawm li cas los xij. kev tsim cov txheej txheem galvanizing qis-cyanide (microcyanide). Ua rau nws muaj peev xwm lav qhov zoo ntawm cov khoom thaum txo cov kev phom sij ib puag ncig. Nyob rau hauv cov txheej txheem cyanide galvanizing, qhov zoo ntawm cov khoom zoo heev tom qab plating cov khoom siv kho vajtse ntawm lub caster. Tshwj xeeb tshaj yog tom qab xim plating tau passivated, cov xim nyob twj ywm rau lub sijhawm ntev.
2, cov lus thiab lub ntsiab lus ntsig txog zincate galvanized caster vuam
Cov txheej txheem zincate galvanizing yog ib txoj hauv kev zoo rau ib puag ncig piv rau cyanide galvanizing. Tam sim no, lawv feem ntau muab faib ua "DPE" series ntawm Wuhan Institute of Materials Protection thiab "DE" series ntawm Guangdian Institute. Ob qho tib si yog zincate galvanized nrog cov khoom ntxiv alkaline. Nws muaj cov yam ntxwv ntawm cov qauv columnar lattice ntawm plating, zoo tiv thaiv corrosion, thiab haum rau xim galvanizing. Nws cov qauv ib txwm muaj xws li NaOH, ZnO, thiab cov khoom ntxiv tshwj xeeb. Piv txwv li, kev sib xyaw ua ke ntawm "DPE-II" thiab ethanolamine. Cov txheej txheem no yuav tsum tau tswj hwm nruj ntawm cov khoom sib xyaw ntawm cov tshuaj plating thiab cov txheej txheem cov xwm txheej. xws li pH, kub, thiab qhov ceev tam sim no. Txhawm rau kom ntseeg tau tias qhov zoo ntawm plating. Tom qab cov khoom tawm hauv lub tank, nws yuav tsum dhau los ntawm ntau cov kauj ruam tom qab ua tiav. xws li ntxuav, polishing, passivating thiab ziab. rau cov txiaj ntsig zoo tshaj plaws.
3, Chloride galvanization
Cov txheej txheem chloride galvanizing yog siv dav hauv kev lag luam caster kho vajtse plating. Feem pua yog siab txog 40%. Cov tsos ntawm cov txheej txheem passivated (xiav-dawb lossis nyiaj-dawb) zoo ib yam li cov chrome plating. Thiab tus nqi qis dua. Cov qauv ib txwm rau chloride galvanizing suav nrog KCl, ZnCl_2, H_3BO_3 (buffer), thiab cov khoom ci ntsa iab tshwj xeeb. Cov txheej txheem no tshwj xeeb tshaj yog rau kev passivation dawb (xiav-dawb, nyiaj-dawb). Ntawm lawv, kev passivation nyiaj-dawb vim nws cov xim ruaj khov. Feem ntau nyiam ua thawj qhov kev xaiv. Txawm li cas los xij. Nws tsim nyog sau cia tias Chloride galvanized coatings, thaum raug cua ntev ntev, yog Lub membrane yooj yim rau discoloration. Cuam tshuam rau qhov tsos thiab corrosion tsis kam ntawm cov khoom. Yog li ntawd. Hauv kev xyaum, nws yog qhov tsim nyog los ua cov kev ntsuas tsim nyog los tiv thaiv discoloration.
4, Kev sib xyaw ua ke ntawm sulfate
Cov txheej txheem sulfate galvanizing, nrog nws tus nqi qis thiab tsim nyog rau kev plating tas mus li (piv txwv li, hlau, strip, thiab lwm yam). Ib qho chaw hauv kev lag luam electroplating. Cov qauv ib txwm muaj rau cov txheej txheem no suav nrog ZnSO_4, H_3BO_3, thiab cov khoom ci ntsa iab tshwj xeeb. Tus nqi pH ntawm sulfate galvanizing feem ntau tswj tau ntawm 4.5 thiab 5.5. Los ntawm kev kho cov khoom sib xyaw ntawm cov tshuaj plating thiab cov xwm txheej ntawm cov txheej txheem, cov txheej txheem A nrog kev tiv thaiv corrosion zoo thiab ci ntsa iab tuaj yeem tau txais. Txawm li cas los xij. Piv rau lwm cov txheej txheem galvanizing, Sulfate galvanizing yuav qis dua me ntsis ntawm qhov ci thiab kev sib xws ntawm cov txheej txheem.
cov lus xaus
Hauv kev xaus. Cov Casters yog galvanized hauv ntau yam txheej txheem. Txhua txoj kev muaj nws tus kheej qhov zoo tshwj xeeb thiab qhov ntau thiab tsawg ntawm daim ntawv thov. Hauv kev xyaum. Yuav tsum raws li qhov chaw siv tshwj xeeb thiab kev ua tau zoo ntawm tus caster. Xaiv cov txheej txheem galvanizing tsim nyog. Lub caij no. Nrog rau cov kev cai ib puag ncig nruj dua thiab kev nce qib hauv kev siv tshuab plating, cov txheej txheem galvanizing uas zoo rau ib puag ncig, ua haujlwm tau zoo thiab raug nqi yuav dhau los ua qhov sib txawv ntawm kev txhim kho yav tom ntej.
