Tsib lub ntsiab lus tseem ceeb ntawm cov khoom siv tshuaj tsuag tsis pub txhaj tshuaj molding txheej txheem

Cov ntaub ntawv tsis muaj tshuaj tsuag yog siv ntau thiab ntau dua, xws li hluav taws xob mov cookers, siab cookers, hluav taws xob kettles, soymilk tshuab, ntxhua khaub ncaws, cua txias thiab lwm yam.cov khoom siv hauv tsev plhaub txhaj tshuaj molding, tsheb pedals, hnab looj tes lub thawv, lub hnub visors, pillar trims, sab tiab thiab lwm yam sab hauv thiab sab nrauv trims tau dhau los ua neeg nyiam. Cov ntaub ntawv tsis muaj tshuaj tsuag yog siv nyob rau hauv ntau qhov chaw, thiab cov ntaub ntawv tsis muaj tshuaj tsuag yog li cov neeg tsim khoom nyiam.

Cov txheej txheem txhaj tshuaj molding ntawm cov yas tsis muaj tshuaj tsuag yog qhov txuas uas tsis tuaj yeem tsis quav ntsej. Cia's saib tsib lub ntsiab lus tseem ceeb ntawm kev txhaj tshuaj molding txheej txheem ntawm cov khoom tsis muaj tshuaj tsuag.


1. Kev tswj kom qhuav: noo noo hauv qab 5%

Cov ntaub ntawv tsis muaj tshuaj tsuag, zoo li feem ntau cov ntaub ntawv, nqus dej vapor hauv huab cua. Nws yuav tsum tau qhuav ua ntej molding, txwv tsis pub, nws yuav ua rau cov nyiaj hlau thiab dej txaws rau ntawm qhov chaw ntawm cov khoom thiab cuam tshuam rau qhov gloss ntawm cov khoom.

Nws yog feem ntau yuav tsum tau tswj cov dej noo ntawm cov khoom tsis muaj tshuaj tsuag hauv qab 0.05 tom qab ziab. Piv txwv li, rau cov khoom tsis muaj tshuaj tsuag ntawm ABS substrate, qhov ziab kub yog feem ntau 70 ° C-85 ° C, thiab qhov kub kom qhuav yog 3-4 teev.

Qhov kub thiab txias heev yuav yooj yim ua rau cov khoom siv degradation, qhov kub thiab txias tsis txaus, lub sij hawm ziab tsis txaus, cov resin noo noo ntau dhau, thiab cov cim roj ntawm cov khoom.

2. Kev txhaj tshuaj kub: nruab nrab thiab qis-kub txhaj tshuaj

Vim qhov sib ntxiv ntawm cov xim hlau rau cov khoom tsis muaj tshuaj tsuag, lub siab shear ntawm cov ntsia hlau tuaj yeem yooj yim ua rau cov xim hlau pigments. Yog li ntawd, lub hauv paus ntsiab lus ntawm kev teeb tsa qhov kub thiab txias rau cov ntaub ntawv tsis muaj tshuaj tsuag yog siv qhov nruab nrab thiab qis-kub txhaj tshuaj molding kom deb li deb tau raws li qhov ua tau kom ntseeg tau tias cov khoom yog cov yas tag nrho los tiv thaiv cov khoom degradation.

Piv txwv li, kev ua haujlwm kub ntawm cov khoom tsis muaj tshuaj tsuag nrog ABS raws li cov khoom siv hauv paus yog 210 ° C-230 ° C. Yog tias qhov kub thiab txias dhau lawm, cov khoom siv yuav raug degraded thiab cov cim huab cua yuav ua rau ntawm qhov chaw ntawm cov khoom.

3. Txhaj ceev: nruab nrab-ceev stepwise tswj

Thaum siv cov ntaub ntawv tsis muaj tshuaj tsuag rau kev txhaj tshuaj molding, kev xaiv ntawm kev txhaj tshuaj nrawm feem ntau txiav txim siab qhov tshwm sim ntawm cov khoom, qhov tso tawm ntawm cov pwm, thiab qhov tsis kam ntawm cov dej ntws hauv cov kab noj hniav ntawm lub tshuab txhaj tshuaj molding.

Qhov kev txhaj tshuaj sai dua feem ntau ua rau cov txheej txheem melting, yog qhov tsim nyog rau kev sau cov khoom siv phab ntsa, thiab ua kom zoo dua qhov tiav thiab cov nyhuv nto. Txawm li cas los xij, kev txhaj tshuaj sai heev yuav yooj yim ua rau cov yaj ua rau muaj zog shear, ua rau muaj kev puas tsuaj rau cov duab thiab qhov loj me ntawm pearlescent toner thiab txo cov xim tshwj xeeb ntawm cov khoom.

Tsis tas li ntawd, cov teeb meem xws li cov cim txhaj tshuaj thiab cov pa tawm tsis zoo yuav tshwm sim ze ntawm lub rooj vag.

Yog li ntawd, nyob rau hauv lub premise ntawm kom ntseeg tau lub nto nyhuv thiab zoo ntawm cov khoom, nws yog pom zoo kom xaiv ib tug nruab nrab-ceev segmented stepped ceev tswj kom ntseeg tau cov ntaub ntawv du thiab cov khoom zoo li.

4. Kev txhaj tshuaj siab: qis dua

Kev txhaj tshuaj siab yog txhawm rau kov yeej qhov tsis kam ntawm cov yaj hauv cov txheej txheem ntws, muab cov yaj ib qho kev ua kom nrawm thiab cog lus thiab pub cov yaj kom ntseeg tau cov txheej txheem du. Qhov kev txhaj tshuaj tiag tiag muaj feem xyuam rau ntau qhov sib txawv, xws li kub kub, pwm kub, ib feem geometry, phab ntsa thickness, ntws ntev, thiab lwm yam pwm thiab cov khoom siv.

Feem ntau, nws yog qhov zoo tshaj plaws los xaiv qhov qis qis uas tuaj yeem ua tau raws li qhov kev ua tau zoo, qhov tsos, thiab lub voj voog txhaj tshuaj. Nyob rau tib lub sijhawm, xyuam xim rau qhov sib txawv ntawm qhov tseeb txhaj tshuaj siab siab thiab cov nqi teev. Feem ntau, qhov tsim nyog tuav siab yog 60-80% ntawm kev txhaj tshuaj.

5. Pwm kub: pwm kub dua

Cov pwm kub ncaj qha cuam tshuam rau qhov ci ntsa iab, cov kab vuam thiab lub zog ntawm cov khoom kawg. Kev siv cov pwm kub kub tuaj yeem ua rau cov khoom siv fluidity, tau txais kev sib txuas lus ntau dua, thiab txo qhov kev ntxhov siab sab hauv ntawm cov khoom pwm los ua kom muaj cua sov-tiv taus thiab tshuaj-resistant, thiab tib lub sij hawm txhim kho cov khoom pwm. replication ntawm yaj mus rau pwm nto, Txhim kho cov khoom gloss thiab tshwj xeeb xim nyhuv.

Txhawm rau kom ua tiav cov txiaj ntsig zoo tshaj plaws saum npoo av, thaum siv cov khoom tsis muaj tshuaj tsuag, yuav tsum tau siv cov pwm kub kom ntau li ntau tau. Rau cov ntaub ntawv tsis muaj tshuaj tsuag nrog ABS ua cov khoom siv hauv paus, pwm kub feem ntau yog 70-90 ° C.

Nyob rau hauv luv luv, tsuas yog tsim pwm tsim, kom qhuav kub, txhaj tshuaj kub, txhaj tshuaj ceev, thiab pwm pwm kub tsim nyog yog indispensable tej yam kev mob rau tshuaj tsuag-dawb cov ntaub ntawv los ua kom zoo nkauj tsos cov khoom.

Ntxiv nrog rau cov txheej txheem txhaj tshuaj molding, kev xaiv cov khoom siv raw kuj tseem ceeb heev. Cov khoom tsis muaj tshuaj tsuag muaj qhov zoo nkauj zoo nkauj thiab zoo nkauj zoo nkauj. Cov ntaub ntawv muaj cua sov ua haujlwm zoo, kev ruaj ntseg zoo, nkag siab, kev ua haujlwm zoo heev, tsim nyog tus nqi ua haujlwm thiab cov khoom siv zoo.
