Kev kho qhov chaw yog ib txoj kev siv los tsim ib txheej saum npoo uas muaj cov yam ntxwv kho tshuab, lub cev, thiab tshuaj lom neeg sib txawv ntawm cov khoom siv hauv paus.

Lub hom phiaj ntawm kev kho qhov chaw yog kom ua tau raws li cov khoom xav tau tshwj xeeb rau kev tiv taus xeb, kev tiv taus hnav, kev kho kom zoo nkauj, thiab lwm yam. Kev sib tsoo tshuab, kev kho tshuaj, kev kho cua sov ntawm qhov chaw, thiab kev txau ntawm qhov chaw yog qee qhov kev siv ntau tshaj plaws ntawm peb cov txheej txheem kho qhov chaw. Lub hom phiaj ntawm kev kho qhov chaw yog los ntxuav, txhuam, tshem tawm cov roj, thiab tshem tawm cov nplai ntawm qhov chaw ua haujlwm. Peb yuav kawm txog cov txheej txheem rau kev kho qhov chaw hnub no.

Feem ntau siv cov txheej txheem nqus tsev electroplating, electroplating, anodizing, electrolytic polishing, pad printing, galvanizing, hmoov txheej, dej hloov luam ntawv, tshuaj ntsuam luam ntawv, electrophoresis, thiab lwm yam kev kho saum npoo av.

1. Kev siv lub tshuab nqus tsev electroplating

Ib qho phenomenon deposition yog lub tshuab nqus tsev. Cov khoom siv raug muab faib ua cov molecule uas raug nqus los ntawm cov khoom siv conductive los tsim ib txheej hlau imitation uas sib xws thiab du thaum cov roj argon raug tso rau hauv lub tshuab nqus tsev thiab ntaus cov khoom siv.

Cov ntaub ntawv siv tau:

1. Muaj ntau yam khoom siv, suav nrog cov hlau, cov polymers mos thiab tawv, cov khoom sib xyaw, cov khoom siv ceramics, thiab iav, tuaj yeem plated los ntawm lub tshuab nqus tsev. Aluminium yog cov khoom siv feem ntau electroplated, ua raws li nyiaj thiab tooj liab.

2. Vim tias cov dej noo hauv cov khoom siv ntuj yuav cuam tshuam rau qhov chaw nqus tsev, cov khoom siv ntuj tsis tsim nyog rau kev plating nqus tsev.

Tus nqi ua haujlwm: Tus nqi ua haujlwm rau lub tshuab nqus tsev plating yog kim heev vim tias cov khoom ua haujlwm yuav tsum tau txau, thauj, tshem tawm, thiab rov txau dua. Txawm li cas los xij, qhov nyuaj thiab ntau npaum li cas ntawm cov khoom ua haujlwm kuj ua lub luag haujlwm rau tus nqi ua haujlwm.

Kev cuam tshuam rau ib puag ncig: Kev siv lub tshuab nqus tsev electroplating ua rau muaj kev puas tsuaj me ntsis rau ib puag ncig li kev txau tshuaj.

2. Kev siv hluav taws xob

Nrog kev pab los ntawm hluav taws xob, cov atoms ntawm ib qho workpiece uas nyob hauv ib qho electrolyte raug hloov mus ua ions thiab tshem tawm ntawm qhov chaw thaum lub sijhawm electrochemical ntawm "electroplating," uas tshem tawm cov burrs me me thiab ua rau qhov chaw ntawm workpiece ci ntsa iab.

Cov ntaub ntawv siv tau:

1. Feem ntau ntawm cov hlau tuaj yeem ua tiav los ntawm kev siv hluav taws xob, nrog rau kev txhuam qhov chaw ntawm cov hlau tsis xeb yog qhov siv nrov tshaj plaws (tshwj xeeb tshaj yog rau cov hlau tsis xeb austenitic nuclear).

2. Nws tsis yooj yim sua kom electropolish ntau yam khoom siv tib lub sijhawm lossis txawm tias nyob rau hauv tib qho kev daws teeb meem electrolytic.

Tus nqi ua haujlwm: Vim tias electrolytic polishing yog qhov tseem ceeb ua haujlwm tsis siv neeg, cov nqi ua haujlwm tsawg heev. Kev cuam tshuam rau ib puag ncig: Electrolytic polishing siv tsawg dua cov tshuaj lom neeg txaus ntshai. Nws yooj yim siv thiab tsuas yog xav tau me ntsis dej kom ua tiav kev ua haujlwm. Tsis tas li ntawd, nws tuaj yeem tiv thaiv kev xeb ntawm cov hlau tsis xeb thiab nthuav cov zoo ntawm cov hlau tsis xeb.

3. Cov txheej txheem luam ntawv Pad

Niaj hnub no, ib qho ntawm cov txheej txheem luam ntawv tshwj xeeb tseem ceeb tshaj plaws yog lub peev xwm luam tawm cov ntawv, cov duab kos, thiab cov duab rau ntawm qhov chaw ntawm cov khoom uas muaj cov duab tsis sib xws.

Yuav luag txhua yam khoom siv siv tau rau kev luam ntawv pad, tsuas yog cov uas mos dua li silicone pads, suav nrog PTFE.

Cov nqi zog ua haujlwm tsawg thiab pwm tsawg yog txuam nrog cov txheej txheem.
Kev cuam tshuam rau ib puag ncig: Cov txheej txheem no muaj kev cuam tshuam rau ib puag ncig siab vim nws tsuas yog ua haujlwm nrog cov kua mem uas yaj tau, uas yog ua los ntawm cov tshuaj lom neeg txaus ntshai.

4. cov txheej txheem zinc-plating

Ib txoj kev hloov kho qhov chaw uas txheej cov hlau alloy cov ntaub ntawv hauv ib txheej zinc rau kev zoo nkauj thiab tiv thaiv xeb. Ib txheej tiv thaiv electrochemical, txheej zinc ntawm qhov chaw tuaj yeem tiv thaiv kev xeb hlau. Galvanizing thiab hot-dip galvanizing yog ob txoj kev siv ntau tshaj plaws.

Cov ntaub ntawv uas siv tau: Vim tias cov txheej txheem galvanizing nyob ntawm cov thev naus laus zis sib txuas ua ke, nws tsuas yog siv tau los kho cov nplaim ntawm hlau thiab hlau.

Tus nqi txheej txheem: lub voj voog luv luv / tus nqi ua haujlwm nruab nrab, tsis muaj tus nqi pwm. Qhov no yog vim tias qhov zoo ntawm qhov chaw ua haujlwm yog nyob ntawm qhov kev npaj ntawm qhov chaw ua ntej galvanizing.

Kev cuam tshuam rau ib puag ncig: Cov txheej txheem galvanizing muaj kev cuam tshuam zoo rau ib puag ncig los ntawm kev ncua lub neej ua haujlwm ntawm cov khoom siv hlau los ntawm 40-100 xyoo thiab tiv thaiv xeb thiab xeb ntawm cov khoom ua haujlwm. Tsis tas li ntawd, kev siv cov kua zinc rov qab yuav tsis ua rau muaj cov tshuaj lom neeg lossis cov khib nyiab lub cev, thiab cov khoom ua haujlwm galvanized tuaj yeem muab rov qab rau hauv lub tank galvanizing thaum nws lub neej siv tau dhau mus.

5. cov txheej txheem plating

Cov txheej txheem electrolytic ntawm kev siv cov txheej txheem ntawm cov hlau zaj duab xis rau ntawm cov khoom siv kom txhim kho kev hnav tsis kam, kev coj ua hluav taws xob, kev cuam tshuam lub teeb, kev tiv thaiv corrosion, thiab kev zoo nkauj. Ntau lub npib kuj muaj electroplating rau ntawm lawv cov txheej sab nraud.

Cov ntaub ntawv siv tau:

1. Feem ntau cov hlau tuaj yeem raug electroplated, txawm li cas los xij qhov huv thiab kev ua haujlwm ntawm kev plating sib txawv ntawm ntau yam hlau. Ntawm lawv, tin, chromium, nickel, nyiaj, kub, thiab rhodium yog cov feem ntau.

2. ABS yog cov khoom siv uas feem ntau siv electroplated.

3. Vim tias nickel muaj kev phom sij rau daim tawv nqaij thiab ua rau khaus, nws tsis tuaj yeem siv los electroplate txhua yam uas kov daim tawv nqaij.

Tus nqi txheej txheem: tsis muaj tus nqi pwm, tab sis xav tau cov khoom siv los kho cov khoom; tus nqi sijhawm sib txawv nrog qhov kub thiab hom hlau; tus nqi ua haujlwm (nruab nrab-siab); nyob ntawm hom khoom plating; piv txwv li, plating cutlery thiab hniav nyiaj hniav kub xav tau tus nqi ua haujlwm siab heev. Vim nws cov qauv nruj rau kev ruaj khov thiab kev zoo nkauj, nws yog tswj hwm los ntawm cov neeg ua haujlwm tsim nyog heev.

Kev cuam tshuam rau ib puag ncig: Vim tias cov txheej txheem electroplating siv ntau yam khoom siv tsis zoo, kev hloov pauv thiab kev rho tawm ntawm cov kws tshaj lij yog qhov tsim nyog los xyuas kom muaj kev puas tsuaj rau ib puag ncig tsawg kawg nkaus.
