Q: Yuav ua li cas kho tshuab kev kho li cas nrog cov npoo txheej?

A: {{1.} kev sib tsoo / txhaj tshuaj blasting
Muaj feem xyuam cov xwm txheej: tshem tawm cov txheej hauv zos (xws li ua ntej vuam muag), tshem tawm cov npoo burrs lossis oxide txheej .
Cov kauj ruam: Siv lub kaum ntse ntse, Sandpaper lossis txhaj tshuaj tiv thaiv cov khoom siv kom zom cov txheej txheej sib tsoo {}}
Cov cheeb tsam sib tsoo yuav tsum tshaj li lub hom phiaj ntau (xws li 20-30 hli ntawm ob sab ntawm lub vuam thaj chaw) kom ntseeg tau tias cov txheej relding) kom ntseeg tau tias cov txheej relding).

2. sandblasting
Muaj feem xyuam nrog cov xwm txheej: Rougening ntawm cov txheej txheem loj-thaj chaw kom txhim kho cov nplaum ntawm cov txheej txheem tom ntej (xws li pleev xim).
Cov kauj ruam: Siv Quartz xuab zeb lossis steel xuab zeb, tswj cov huab cua siab ntawm {}} mpa mpa .
Qhov saum npoo ntsug tom qab sandblasting yog pom zoo kom ncav cuag ra 3.2-6.3 .

 

Q: Cov tshuaj kho mob ua li cas kho cov txheej txheem plaub hau?

A: {1.} pickling passivation
Muaj feem xyuam nrog cov xwm txheej dawb: Tshem tawm cov xeb dawb dawb lossis cov npoo oxides los kho cov haujlwm ntawm txheej .
Cov kauj ruam: Soak lossis so nrog dilute hydrochloric acid (5%-10%) lossis citric acid tov rau diss acid oxide / aluminium.
Tom qab yaug nrog dej huv, siv chromate lossis silane passivation daws los tsim zaj duab xis .

2.} Xyaw kho
Muaj feem cuam tshuam: Qhov txheej yuav tsum tau muab tshem tawm tag nrho (xws li kho hauv lub zos lossis rov qab ua kom rov zoo) .
Cov kauj ruam: Soak lub aluminium-zinc phaj nyob rau hauv ib qho muaj zog alkaline (xws li naoh {1} {{2} degree).
Suav txog thaum cov txheej tag nrho (aluminium-zinc reacts nrog alkali los ua aluminali los ua aluminate thiab zincate).
Acid ntxuav kom neutralize cov kev daws teeb meem alkali, yaug nrog dej huv thiab qhuav.

Q: Ua li cas cov kev kho cua sov kho tau kho cov txheej txheej saum npoo hlau?

A: Diffusion Annaling
Muaj cov xwm txheej muaj zog: Txhim kho lub zog sib npaug ntawm txheej thiab cov txheej txheem ntawm cov txheej thiab txo cov brittleness ntawm txheej {}}
Cov kauj ruam: cua sov rau {300-400℃hauv qab kev tiv thaiv roj av thiab ua kom sov {}.
Maj mam txias los txhawb kev sib txawv ntawm txhuas thiab zinc me ntsis rau hauv cov txheej txheem los ua ib txheej sib txawv .

Aluminum galvanized

Q: Qhov kev kho txheej txheem txheej txheem?

A: {{1.}} txias txau ntawm zinc thiab txhuas
Muaj feem ntau cov xwm txheej: Kev kho cov txheej txheem hauv zos puas (xws li khawb thiab ua pob) .
Cov kauj ruam: Siv Sandblasting los ntxuav thaj chaw puas rau sa2 . 5 kev huv.
Siv cov khoom txau txias kom tsuag zinc thiab txhuas hmoov mus rau saum npoo ntawm qhov kev kub ceev los ua cov txheej txheem dense .

2. Electrophoresis rov ua plating
Cov xwm txheej muaj feem: kho cov kev sib xyaw ntawm cov txheej ntawm cov seem ntawm qhov ntsuas ntshav .
Cov kauj ruam: tshem tawm cov workpiece hauv lub tshuab hluav taws xob muaj cov zinc thiab aluminium ions, thiab ion directional deposition tom qab fais fab tau muab rau .
Kho cov voltage ({0}} v) thiab sijhawm ({{}}} feeb).

Q: Dab tsi yuav tsum tau them nyiaj rau tom qab kev kho plating?

A: Kev ntsuas kev sib cav: qhov kho cov txheej yuav tsum tau ua kom haum rau cov txheej txheem tom qab (xws li vuam thiab pleev xim rau kev sim ib qho piv txwv me me sim ua ntej.
Kev tswj hwm ib puag ncig: siv tshuaj lom neeg yuav tsum tau nruab nrog qhov cua thiab khib nyiab ua kua rov qab kom tsis txhob muaj kuab paug .
Txheem Ua Raws: Xaiv txoj kev kho mob raws li cov qauv xws li GB / T 14978 (txuas ntxiv cov phaj-zinc aluminium phaj).
