Cov txheej txheem kev kho mob saum npoo ntawm txhuas tuag - case caste

Aluminium tuag casting qhov chaw nrog lub teeb hnyav, muaj zog ua tau zoo rau kev ua haujlwm ntawm cov khoom lag luam corrosion, thiab lwm qhov chaw ua haujlwm ntawm cov khoom lag luam zoo heev, puas yog cov khoom lag luam zoo.

Nto Kho Tshuab yog feem ntau yog cais rau hauv peb pawg hauv qab no:

 

 

Hom thev naus laus zis no tsuas yog txhim kho cov khoom saum npoo ntawm lub cev.

Xuab zeb / Tua Minesening: Siv cov xuab zeb lossis cov tshuaj pleev pob zeb zoo nkauj muab cov khoom zoo nkauj

POLISHING: Nws tau muab faib ua ke polishing, tshuaj lom neeg cov tsos kom zoo nkauj, tshwj xeeb tshaj yog cov khoom lag luam nrog cov khoom muaj zog.

 

 

Ib zaj duab xis hloov lossis txheej yog tsim nyob rau saum npoo los ntawm kev siv tshuaj lom neeg.

Pretreatment (degreasing, pickling, pickling): Nov yog qhov tseem ceeb rau lwm txoj kev kho tom ntej. Degreas kom tshem tawm cov roj stains, acid ntxuav kom tshem oxides, ua rau cov kev huv si thiab nquag ua kom zoo ntawm kev kho tom ntej.

Anodizing: Nws yog ib qho tseem ceeb tshaj plaws thiab dav thev naus laus zis. Thaum ib qho txhuas ib feem yog siv los ua anode thiab electrified nyob rau hauv electrolyte, ib qho nyuaj ntxig aluminium oxide zaj duab xis oxide zaj duab xis ntawm nws nto. No zaj duab xis txheej yog corrosion - tiv taus, insulating, thiab nws cov qauv sib dhos tuaj yeem adsorb dyes, ua tiav ntau yam xim. Nws tseem muaj cov khoom tiv thaiv zoo thiab zoo nkauj thiab yog siv dav hauv lub tsev thiab lub qhov rais, hluav taws xob nrog lwm thaj chaw.

Tshuaj Plating Plating: nyob rau hauv qhov kev mob ntawm tsis muaj qhov tam sim no, xws li Nickel hlau (xws li Nickel) tau muab tso rau saum npoo los ntawm kev siv tshuaj lom neeg. Nws tau txais txiaj ntsig zoo kom tau txais cov txheej txheem tuab tuab ntawm cov nyom, zoo li cov khoom ua kom zoo, hnav tsis kam thiab hluav taws xob conduction thiab hluav taws xob conduction thiab hluav taws xob conduction thiab hluav taws xob conduction thiab hluav taws xob conduction thiab hluav taws xob conductivity.

Phosphating: ib qho phosphate hloov zaj duab xis yog tsim nyob rau saum npoo los ntawm kev raus nyob rau hauv phosphating tov. Daim yeeb yaj kiab txheej no feem ntau yog txhim kho corrosion tsis kam thiab tuaj yeem txhim kho cov nplaum ntawm cov txheej txheem organic (xws li cov tshuaj pleev tshuaj tsuag), thiab yog siv ua ntej ua ntej ua ntej tha xim.

 

 

Npog lub npoo nrog cov txheej txheem organic los ntawm cov hau kev lossis hluav taws xob.

Txau

Hmoov hmoov: cov hmoov hmoov kom qhuav yog txuas nrog cov khoom cua kub thiab cov xim muaj txiaj ntsig, thiab cov khoom siv nplua nuj, txhuas tau siv hauv tsev thiab rooj tog zaum fittings.

Cov tshuaj tsuag ua kua: Txais yuav cov tsoos tsuag rab phom txau cov xim thiab tsim cov duab zoo nkauj, siv rau cov khoom ua kom zoo nkauj sab hauv, thiab lwm yam.

Electrophoretic txheej: immersed imagicts hauv Electrophoretic Xim, muaj zog yog siv rau cov khoom lag luam zoo heev, xws li tsheb hub.

 

 

Thaum xaiv cov thev naus laus zis deg, nws yog ib qho tsim nyog xav tau kev txiav txim siab tshwj xeeb, xws li cov huab cua tsis zoo, ua tau zoo rau huab cua, kev ua haujlwm zoo li qub, ua kom cov khoom lag luam kom tau zoo, txhim kho cov khoom lag luam ntxiv.
