Yas Electroplating Khwv:
ABS Plastics feem ntau yog siv rau kev kho qhov muag ntawm cov khoom yas.Qhov cov txheej txheem dav dav yog degreasing, roughening, rhiab siab, ua kom zoo,
electroless npib tsib xee plating lossis electroless tooj liab plating, tuab ntawm tooj liab plating, thiab txheej txheej plating.Qhov txheej txheej feem ntau suav nrog nickel, chromium, qog kub, thiab lwm yam, nyob ntawm qhov xav tau.
Cov txheej txheem electroplating:
1.Cleaning: Txhawm rau tshem tawm cov av thiab cov ntiv tes sab laug thaum lub sijhawm yas txheej txheem yas, nws tuaj yeem ntxuav nrog tus neeg sawv cev alkali, tom qab ntawd nruab nrab nrog cov kua qaub ua kom lub cev thiab ntxuav nrog dej.
2.Txoj kev kho mob: ntub cov nplaim yas kom sib cuam tshuam nrog cov txias ntawm cov kauj ruam tom ntej.
3.Txoj kev ua haujlwm: Cov nplaim yas yog roughened rau hauv qhov chaw kaw sab hauv kom ua rau cov plating txheej kaw thiab tsis yooj yim rau tev tawm, tseem hu ua tshuaj roughening.
4.Sensitization: Adsorb tus txo tus neeg sawv cev nyob rau saum npoo, feem ntau siv (stannous chloride) lossis lwm yam tin sib txuas, uas yog, sn ions yog adsorbed ntawm cov yas thiab muaj qhov txo nto.
Zoo ntawm cov yas plating:
1.Easy kom yooj yim rau cov duab thiab cov duab zoo.
2.Tshooj hnyav.
3. zoo corrosion kuj.
4.Qhov zoo tshuaj.
5.Txhais zoo heev hluav taws xob rwb thaiv tsev.
6.Qhov nqi.
7.Cov khoom lag luam tuaj yeem tsim tawm.
Kev tsis zoo ntawm cov yas plating:
1. Huab cua tsis kam ua kom yooj yim, yooj yim kom embrittled los ntawm lub teeb.
2. Kev tiv tshav kub kub tsis zoo.
3. Lub tshuab ua tau raug yog qhov me me.
4. tsis coj zoo kuj.
5. Qhov siab nqus dej.
Yas Electroplating Mould Tsim:
Txhawm rau kom ntseeg tau tias tsis muaj qhov tsis sib xws ntawm sab nrauv ntawm cov yas plating feem, tsis muaj qhov pom tseeb ntawm cov qauv thiab kev ntxhov siab sab hauv, cov kev cai hauv qab no yuav tsum tau ua tiav thaum tsim qauv thiab tsim pwm.
1. Cov khoom siv pwm yuav tsum tsis txhob ua cov beryllium bronze alloy.Nws yuav tsum tau ua los ntawm lub siab zoo nqus cam khwb cia hlau.Qhov saum npoo ntawm kab noj hniav yuav tsum tau polished rau daim iav-ci ci raws cov pwm ejection kev taw qhia, thiab qhov tsis sib xws yuav tsum yog tsawg dua 0.2 hli.Qhov nto yog zoo plated nrog nyuaj chrome.
2. Cov nplaim ib feem ntawm cov yas ntu ncaj ncees cuam tshuam qhov saum npoo ntawm cov pwm kab noj hniav, yog li cov kab noj hniav ntawm lub qhov yas electroplated yuav tsum ua kom zoo, thiab qhov saum npoo ntawm cov pwm kab noj hniav yuav tsum yog 1 txog 2 qib siab tshaj qhov chaw ntawm lub npoo. ntawm ib feem.
3. Qhov chaw ntawm npoo, weld kab thiab cov tub ntxhais inlay kab tsis tuaj yeem tsim ntawm cov plating nto.
4. Lub qhov rooj laj kab yuav tsum tsim ntawm qhov chaw tuab ntawm ntu.Qhov kom tiv thaiv cov yaj tsis txhob txias dhau thaum sau pwm qhov kab noj hniav, lub rooj vag yuav tsum loj npaum li sai tau (kwv yees li 10% loj dua qhov txhaj tshuaj pwm) .Nws yog qhov zoo tshaj plaws los siv lub rooj vag thiab khiav nrog lub voj voos hla kev, thiab qhov ntev ntawm tus neeg khiav yuav tsum luv dua.
5. Lub qhov tso pa tawm yuav tsum tseg kom tsis txhob muaj qhov tsis xws luag xws li lub tshuab lim cua thiab lub npuas thaiv lub ntsej muag ua haujlwm.
6. Thaum xaiv lub ejector mechanism, xyuas kom du ntawm demolding ntawm ib feem.
ABS Platic yog ib qho ntawm feem ntau siv hauv cov yas electroplating.ABS Yas yog terpolymer ntawm acrylonitrile (A), butadiene (B) thiab styrene (S) .Rau electroplating qib ABS Plastics, cov ntsiab lus ntawm butadiene muaj kev cuam tshuam zoo ntawm electroplating , thiab yuav tsum tswj feem ntau ntawm 18% mus rau 23% .Hauv cov ntsiab lus butadiene, fluidity zoo, yooj yim rau cov duab, thiab zoo adhesion rau lub txheej.Vim ABS yog ib tus neeg tsis coj, txheej txheej yuav tsum tau txuas ua ntej electroplating.
Kev txhaj tshuaj:
Kev txhaj tshuaj moulded qhov chaw txuas yam tsis muaj kev ntxhov siab sab hauv vim cov yam ntxwv ntawm cov txheej txheem molding, tab sis kev tswj kom zoo ntawm cov txheej txheem cov txheej txheem yuav txo qhov kev ntxhov siab sab hauv ntawm cov ntu yas ua ntu zus mus rau qhov kawg thiab ua kom paub tseeb tias kev siv ntawm cov seem.Peb tsis raug, cov txheej txheem tsis muaj kev tswj hwm kom zoo, yuav muaj kev ntxhov siab ntau ntawm sab hauv, uas yuav tsis tsuas yog txo lub zog ntawm ib feem, tab sis kuj warp thiab deform lossis tseem tawg thaum lub sijhawm cia thiab siv, uas yuav ua rau lub txheej tawg lossis txawm tias poob tawm.Yog li ntawd, kev tswj cov txheej txheem tsis pub dhau yuav tsum ua kom muaj kev ntxhov siab sab hauv ntawm qhov me me li sai tau.Qhov txheej txheem kev tswj hwm yuav suav nrog cov khoom nyoos qhuav, pwm kub, kev ntsuas kub, txhaj tshuaj nrawm, txhaj tshuaj lub sijhawm, txhaj tshuaj siab, tuav lub siab, tuav lub sijhawm, lub sijhawm txias, thiab lwm yam.
Kev kho tom qab kos duab:
Vim tias kev txhaj tshuaj moulding, kev siv lub tshuab xaiv, qhov tsim thiab pwm tsim, kev ntxhov siab sab hauv muaj qhov sib txawv ntawm cov khoom seem ntawm cov yas mus rau qib sib txawv, uas yuav ua rau lub zos tsis sib haum, ua kom muaj kev nyuaj thiab ua kom cov hlau, thiab thaum kawg ua rau hlau hlau tshuaj txheej yog tsis tiv taus kev sib tsoo thiab txo qis kev sib txuas lub zog.Qhov qhia tau hais tias ob qho tib si kev kho cua sov thiab txheej txheem ntawm tus neeg sawv cev kho tau zoo tuaj yeem txo thiab tshem tawm kev ntxhov siab sab hauv ntawm cov yas, thiab nce qhov sib zog ntawm cov txheej los ntawm 20-60%.
Ntxiv mus, cov yas pwm yas yuav tsum tau ntim tshwj xeeb thiab cais tawm, thiab nws yog nruj me ntsis txwv tsis pub khawb lossis kos qhov chaw, kom tsis txhob cuam tshuam rau qhov pom ntawm electroplating.During kev kuaj xyuas, tus kuaj xyuas yuav tsum hnav hnab looj tes kom tiv thaiv kev sib kis ntawm qhov saum npoo ntawm plated qhov chaw thiab cuam tshuam rau kev nplaum ntawm lub txheej.
