Kev soj ntsuam ntawm kev ua tsis tiav ntawm cov yas plating Yuav ua li cas txhawm rau txhim kho cov txheej txheem txhaj tshuaj molding thiab txhim kho electroplating kev ua tau zoo ntawm PC / ABS?

plating PC / ABS qhov chawtau dav siv hauv tsheb, khoom siv hauv tsev thiab IT kev lag luam vim lawv cov xim zoo nkauj zoo nkauj. Cov txheej txheem tsim cov khoom siv thiab cov txheej txheem electroplating feem ntau suav tias yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm electroplating ntawm PC / ABS. Txawm li cas los xij, ob peb tus neeg mob siab rau qhov cuam tshuam ntawm kev txhaj tshuaj molding txheej txheem ntawm electroplating kev ua tau zoo.


Txhaj kub

Nyob rau hauv cov xwm txheej uas cov khoom yuav tsis tawg, qhov kev txhaj tshuaj ntau dua tuaj yeem tau txais kev ua haujlwm zoo electroplating.

Ntawm qhov ntsuas kub qis dua, qhov fluidity ntawm PC / ABS cov ntaub ntawv tsis zoo, thiab cov khoom txhaj tshuaj molded muaj kev ntxhov siab ntau dua. Cov kev ntxhov siab yog tso tawm thaum lub sij hawm roughening txheej txheem, uas ua rau uneven etching nyob rau saum npoo ntawm cov khoom, uas nyob rau hauv lem ua rau cov tsis zoo tsos ntawm cov khoom electroplated, thiab cov neeg pluag bonding quab yuam ntawm electroplating tshwm sim.

Kev txhaj tshuaj ntau dua tuaj yeem txo qhov seem sab hauv ntawm cov khoom, yog li txhim kho cov khoom siv electroplating. Cov kev tshawb fawb cuam tshuam tau pom tias piv rau cov khoom siv nrog kev txhaj tshuaj kub ntawm 230 ° C, thaum qhov kub nce mus rau 260 ° C-270 ° C, qhov adhesion ntawm cov txheej yog nce li ntawm 50%, thiab qhov zoo li qhov tsis xws luag. kuj txo qis heev.

Txawm li cas los xij, kev txhaj tshuaj kub yuav tsum tsis txhob siab dhau. Yog tias qhov kub ntawm pyrolysis ntawm cov khoom siv ntau dhau, cov tsos ntawm cov khoom siv tshuaj pleev xim yuav tsis zoo, uas yuav cuam tshuam rau nws txoj kev ua haujlwm electroplating.

Txhaj ceev thiab siab

Kev txhaj tshuaj qis dua thiab kev txhaj tshuaj nrawm yog qhov zoo los txhim kho electroplating kev ua tau zoo ntawm PC / ABS.

Kev txhaj tshuaj ntau dhau yuav ua rau muaj kev sib tsoo ntau dhau ntawm cov khoom siv molecules, uas ua rau cov khoom muaj kev ntxhov siab ntau dua, uas yuav ua rau cov khoom tsis sib xws coarsening thiab tsis zoo electroplating bonding quab yuam;

Kev ua kom nrawm nrawm nrawm tuaj yeem ua kom cov shear ntawm lub rooj vag txoj haujlwm, ua rau muaj qhov nce hauv cov dej kub, uas yuav ua rau kom cov dej ntws ntawm tag nrho cov khoom, uas yog qhov zoo rau kev ntim cov khoom thiab txo cov kev ntxhov siab sab hauv. cov khoom; tab sis ntau heev sheer yuav ua rau cov khoom tawg ntawm cov pyrolysis yuav ua rau huab cua cim, tev, burrs thiab lwm yam teeb meem.

Tuav siab thiab tuav lub siab hloov taw tes

Kev tuav siab dhau lawm thiab lig tuav lub siab hloov txoj haujlwm tuaj yeem yooj yim ua rau cov khoom ntim ntau dhau, kev ntxhov siab ntawm lub rooj vag txoj haujlwm, thiab kev ntxhov siab ntau dua hauv cov khoom. Yog li ntawd, nws yog ib qho tsim nyog los teeb tsa lub siab tuav thiab tuav lub siab hloov taw tes ua ke nrog cov khoom ntim khoom tiag.

Pwm kub

Cov pwm kub kub yog qhov zoo los txhim kho cov khoom siv electroplating.

Nyob rau hauv lub xeev uas tsis muaj pwm kub, cov khoom muaj fluidity tsis zoo. Vim lub extrusion thiab stretching ntawm molecules thaum lub sij hawm filling txheej txheem ntawm cov khoom, lub molecular saw orientation ntawm cov khoom tom qab cov khoom yog txias cia yog loj, lub internal kev nyuaj siab ntawm cov khoom yog loj, thiab cov electroplating kev ua tau zoo yog tsis zoo. ; Ntawm qhov tsis sib xws, nyob rau hauv lub xeev ntawm pwm kub kub, cov khoom muaj fluidity zoo, uas yog conducive mus sau, molecular saw nyob rau hauv ib tug natural curl, lub internal kev nyuaj siab ntawm cov khoom yog me me, thiab cov electroplating kev ua tau zoo heev. .

Qhov tseeb pwm qhov kub thiab txias yuav tsum tau teem caij raws li qhov yuav tsum tau ntawm cov pwm dej, cua sov txoj kev thiab molding voj voog. Tsis muaj kev cuam tshuam rau lwm yam khoom, pwm kub yuav tsum tau nce ntau li ntau tau; Thaum tswj cov pwm kub, nws yog ib qho tsim nyog yuav tsum tswj kom muaj qhov sib txawv ntawm qhov pwm pwm, qhov kub tsis sib xws pwm yuav ua rau tsis sib xws shrinkage hauv kev ntxhov siab thiab cuam tshuam rau kev ua haujlwm ntawm electroplating.

Ntsia hlau ceev

Cov ntsia hlau qis qis yog qhov zoo los txhim kho cov khoom siv electroplating.

Kev teeb tsa ntawm cov ntsia hlau ceev yog tswj xyuas lub sij hawm ntsuas ntawm cov yas, uas yog, lub sij hawm rau cov yas nkag mus rau hauv lub thoob thiab tau txais cov ntsia hlau rau kev sib tov, thiab xa mus rau lub nozzle.

Cov ntsia hlau ceev kuj tseem cuam tshuam rau qhov sib xws ntawm plasticization. Ceev ceev ceev ceev yuav ua rau kom cov shear ntawm cov khoom nyob rau hauv cov ntsia hlau, thiab melting kub yuav nce sharply. Tsis tas li ntawd, qhov ceev ntawm cov ntsia hlau ceev, qhov sib xyaw ua haujlwm ntawm cov yas yog qhov tsis zoo, thiab kev tsim cov yaj Cov qhov sib txawv ntawm qhov kub thiab txias ua rau cov filling ntws thiab txias kuj ua rau qhov sib txawv, uas yog ib qho laj thawj tseem ceeb rau kev tsim cov kev ntxhov siab sab hauv. hauv cov khoom.

Yog li ntawd, feem ntau hais lus, nyob rau hauv lub premise ntawm kom ntseeg tau lub melting ntawm cov khoom, cov ntsia hlau ceev yog teem kom lub metering lub sij hawm me ntsis luv dua lub sij hawm txias.

Cov ntsiab lus:

Hauv kev txhaj tshuaj molding txheej txheem, kev txhaj tshuaj kub, txhaj tshuaj ceev thiab siab, pwm kub, tuav siab, ntsia hlau ceev, thiab lwm yam yuav cuam tshuam rau electroplating kev ua tau zoo ntawm PC / ABS.

Qhov cuam tshuam ncaj qha tshaj plaws yog kev ntxhov siab ntau dhau ntawm cov khoom. Kev ntxhov siab ntau dhau los yuav cuam tshuam rau qhov sib xws ntawm etching thaum lub sij hawm electroplating coarsening theem, thiab tom qab ntawd cuam tshuam rau electroplating bonding quab yuam ntawm cov khoom kawg.

Nyob rau hauv luv luv, nws yog ib qho tsim nyog los muab cov khoom tsim, pwm txheej xwm, thiab molding tshuab raws li txoj cai, thiab sim txo qhov kev ntxhov siab ntawm cov khoom los ntawm kev teeb tsa cov txheej txheem txhaj tshuaj tsim nyog, uas tuaj yeem txhim kho cov electroplating kev ua tau zoo ntawm PC / ABS cov ntaub ntawv.
