(33) Tsis zoo gloss ntawm cov khoom yas (iav fiber ntau nag lossis daus) Txhaj Molding Txheej Txheem Tsis Zoo Los Ntawm Txhais Tes

Dab tsi yog gloss phem?
Cov gloss tsis zoo yog hais txog cov khoom molded tsis adhering rau pwm, uas txhais tau tias tsis zoo replication.
Yog vim li cas rau gloss tsis zoo
(2-1) Ua los ntawm cov tshuaj tsuag los yog cov khoom txias
Thaum cov tshuaj tsuag los yog cov ntaub ntawv txias tshwm rau saum npoo ntawm cov khoom tsim, lawv tshwm sim raws li qhov muag plooj li pos huab vim lawv qhov sib txawv ntawm ib puag ncig ib puag ncig. Nws feem ntau tshwm sim ze ntawm lub rooj vag thiab hauv qhov chaw tsis sib xws.
(2-2) Vim muaj roj
Qhov no yog vim hais tias cov roj yog thaiv ntawm cov pwm thiab cov resin thiab cuam tshuam cov adhesion ntawm ob, ua rau tsis zoo gloss. Nws yog qhov tshwm sim ntau dua thaum tuav lub siab qis lossis qhov tso pa tsis zoo.
(2-3) Vim lub siab tsis txaus
Vim qhov tsis tshua muaj siab, qhov extrusion siab ntawm cov pwm nto ntawm cov resin tsis muaj zog, ua rau tsis zoo gloss. Nyob rau hauv cov ntaub ntawv uas muaj fillers xws li iav fiber, tsis zoo gloss yuav tshwm sim vim lub fact tias cov muab tub lim nyiam ntab tawm ntawm qhov chaw (cov resin nyhav rau hauv dab dej).
Piv txwv li, thaum qhov kev txhaj tshuaj ceev qis, lub siab tsis tuaj yeem xa mus rau qhov kawg vim yog cov resin solidification, uas tuaj yeem ua rau tsis zoo gloss ntawm qhov kawg ntawm cov khoom molded. Nyob rau tib lub sijhawm, thaum pwm kub qis thiab qhov kev kho tag nrho yog ceev ceev, gloss tsis zoo kuj yuav tshwm sim rau tag nrho cov khoom pwm.
(3) Kev ntsuas tsis zoo rau gloss
Ua ntej, sim ua kom lub siab tuav tus nqi thiab lub siab tuav lub sij hawm teeb tsa tus nqi. Koj yuav tsum pom qhov xwm txheej zoo dua ntawm qhov no. Yog tias tsis yog, nws tuaj yeem txiav txim siab tias qhov nce siab ntawm qhov no tsis txaus vim yog lwm yam laj thawj. Lub sijhawm no, cov kev ntsuas hauv qab no yuav tsum tau siv ib txhij:
Nce pwm kub
Nce chim kub (tshwj xeeb tshaj yog nozzle)
Nce qhov rooj loj
Nce kev txhaj tshuaj nrawm
Siv cov ntaub ntawv qib nrog zoo fluidity
1, Txhaj pwm
"Yog hais tias cov pwm kab noj hniav tsis zoo, xws li qhov tsis xws luag xws li nti, micropores, hnav, thiab roughness, nws yuav tsum tau ua raws li cov khoom yas, ua rau cov yas tsis zoo. muaj me me roughness nyob rau saum npoo ntawm pwm kab noj hniav, thiab yog tias tsim nyog, nws tuaj yeem polished thiab chrome plated. "
Yog hais tias muaj roj thiab dej stains nyob rau saum npoo ntawm cov pwm kab noj hniav, los yog siv ntau tshaj tawm tus neeg sawv cev, lub nto ntawm cov yas yuav ua tsaus thiab ci. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau tshem tawm cov roj thiab dej stains tam sim ntawd, thiab siv ib qho kev txwv tus neeg tso tawm.
Yog tias cov pwm tso tawm lub kaum sab xis ntawm cov yas me me dhau, nws nyuaj rau kev tso tawm, lossis lub zog siv thaum lub sij hawm tso tawm pwm loj dhau, ua rau lub ntsej muag zoo ntawm cov yas, lub pwm tso tawm lub kaum sab xis yuav tsum tau nce ntxiv.
4. Yog tias cov pwm tso tawm tsis zoo thiab cov pa roj ntau dhau nyob rau hauv cov qauv, nws tuaj yeem ua rau tsis zoo gloss. Yog li ntawd, nws yog ib qho tsim nyog los xyuas thiab kho cov pwm tso tawm qhov system.
"Yog hais tias qhov cross-sectional cheeb tsam ntawm lub rooj vag los yog khiav yog me me heev los yog dheev hloov, lub shear quab yuam ua rau lub yaj thaum ntws nyob rau hauv nws loj heev, ua rau turbulent dynamic flow, ua rau tsis zoo gloss. thaj tsam ntawm lub rooj vag thiab tus khiav yuav tsum tau nce kom tsim nyog. "
Nws yuav tsum tau kuaj xyuas seb cov roj tau raug tso tawm tag lawm.
Tshawb xyuas seb qhov tuab thiab qhov loj ntawm qhov chaw nres nkoj puas yuav tsum tau ua kom muaj txiaj ntsig zoo, thiab seb lawv puas muaj kab mob pwm. Txawm hais tias nws tau teeb tsa rau qhov chaw tsim nyog kuj tseem ceeb. Yog tias ua tau, nws raug pom zoo kom siv cov txheej txheem luv luv kom nkag siab txog qhov tseeb ntawm cov dej ntws.
2, Txhaj tshuaj molding txheej txheem
Yog tias qhov kev txhaj tshuaj ceev yog qhov me me heev, qhov saum npoo ntawm ib feem me me tsis ntom thiab ua kom muaj kev txhaj tshuaj tsis zoo, yuav muaj kev nce ntxiv.
"Rau cov phab ntsa tuab tuab, yog tias qhov cua txias tsis txaus, lawv qhov chaw yuav ua plaub hau thiab ci, thiab vim li no, cov cua txias yuav tsum tau txhim kho."
Yog tias qhov tuav lub siab tsis txaus thiab lub sijhawm tuav yog luv dhau, ua rau tsis txaus thiab tsis zoo ntawm cov yas, qhov tuav tuav thiab tuav lub sijhawm yuav tsum tau nce ntxiv.
5. Yog hais tias lub melting kub yog tsawg dhau, uas ua rau cov fluidity tsis zoo thiab gloss tsis zoo, nws yog ib qho tsim nyog yuav tsum tau ua kom lub melting kub kom tsim nyog.
"Rau cov khoom yas ua los ntawm crystalline resins xws li PE, PP, POM, thiab lwm yam., qhov tsis sib xws tuaj yeem ua rau lub ntsej muag tsis zoo. Yog li ntawd, lub tshuab cua txias yuav tsum tau txhim kho kom ntseeg tau tias cov cua txias tsis sib xws."
"Yog tias qhov kev txhaj tshuaj nrawm dhau lawm thiab lub rooj vag ntu ntu me me dhau lawm, qhov chaw casting yuav tsaus thiab ci ntsa iab nyob ze ntawm qhov casting. Vim li no, nws raug nquahu kom tsim nyog txo qhov kev txhaj tshuaj nrawm thiab ua kom lub rooj vag hla- cheeb tsam. "
3, Cov khoom siv raw
1. Lub particle loj sib txawv ntawm raw cov ntaub ntawv yog loj, ua rau nws nyuaj rau uniformly plasticize, thiab lub gloss yog tsis zoo. Yog li ntawd, cov khoom siv raw yuav tsum tau kuaj xyuas
"Cov khoom siv siv ntau dhau los yog cov khoom siv nozzle ntxiv rau cov khoom siv raw, uas cuam tshuam rau cov txheej txheem plasticization ntawm cov yaj thiab ua rau lub ntsej muag tsis zoo. Yog li ntawd, cov khoom siv rov ua dua lossis cov khoom siv nozzle ntxiv yuav tsum raug txo."
Qee cov ntaub ntawv raw yuav decompose thiab discolor thaum hloov kub, ua rau tsis zoo gloss. Yog li ntawd, cov khoom siv raw nrog qhov kub thiab txias yuav tsum tau xaiv.
"Cov dej noo lossis cov ntsiab lus tsis hloov pauv hauv cov khoom siv raw yog siab dhau, thiab thaum rhuab, nws evaporates rau hauv cov pa roj, uas condenses nyob rau hauv pwm kab noj hniav thiab yaj, ua rau tsis zoo gloss ntawm cov yas ib feem. Yog li ntawd, cov khoom raw yuav tsum tau ua ntej. qhuav."
5. Ib co additives muaj dispersibility tsis zoo, ua rau tsis zoo gloss ntawm yas qhov chaw. Yog li ntawd, cov additives uas muaj kev ua tau zoo txaus yuav tsum tau siv xwb.
"Cov khoom siv raw yog sib xyaw nrog cov khoom txawv teb chaws, lwm yam khoom siv, lossis cov khoom siv tsis tuaj yeem, uas tsis tuaj yeem sib xyaw nrog lawv cov ntaub ntawv raw, ua rau tsis zoo gloss. Yog li, cov khoom siv sib txawv no yuav tsum raug txwv nruj ua ntej."
Yog hais tias tus nqi ntawm cov roj nplua nyeem tsawg dhau, qhov fluidity ntawm cov yaj yog qhov tsis zoo, thiab qhov saum npoo ntawm cov yas tsis yog compact, ua rau tsis zoo gloss. Yog li ntawd, tus nqi ntawm cov roj nplua nyeem yuav tsum tau nce kom tsim nyog.
