1. Pwm tsis ua hauj lwm
Vim lub fact tias qhov saum npoo ntawm cov yas yog ib tug reproduction ntawm cov pwm kab noj hniav nto, yog hais tias muaj defects nto xws li khawb, corrosion, thiab micropores ntawm pwm nto, lawv yuav tsum reflected nyob rau saum npoo ntawm cov yas, ua rau tsis zoo gloss. Yog hais tias qhov chaw ntawm cov pwm kab noj hniav muaj paug nrog cov roj, noo noo, los yog siv ntau tshaj tawm tus neeg sawv cev los yog xaiv tsis raug, nws kuj tuaj yeem ua rau qhov chaw ntawm cov yas tsaus.
Yog li ntawd, qhov saum npoo ntawm cov pwm kab noj hniav yuav tsum muaj cov smoothness zoo, thiab nws yog qhov zoo tshaj plaws los siv polishing kho los yog nto chrome plating. Qhov saum npoo ntawm cov pwm kab noj hniav yuav tsum tau ua kom huv si thiab ntxuav tam sim ntawm cov roj thiab dej stains. Qhov ntau thiab ntau npaum li cas ntawm tus neeg tso tawm yuav tsum tsim nyog.
Pwm kub kuj tseem muaj feem cuam tshuam rau qhov zoo ntawm cov khoom yas. Feem ntau, cov khoom sib txawv ntawm cov yas muaj qhov sib txawv tseem ceeb hauv qhov chaw gloss nyob rau hauv cov pwm kub sib txawv. Ntau dhau los yog tsis txaus pwm kub tuaj yeem ua rau tsis zoo gloss. Yog tias cov pwm kub qis dhau lawm, cov khoom molten yuav solidify tam sim ntawd tom qab kev sib cuag nrog cov pwm kab noj hniav, uas yuav txo tau cov reproducibility ntawm pwm kab noj hniav nto. Txhawm rau ua kom gloss, pwm kub tuaj yeem tsim nyog. Nws yog qhov zoo tshaj plaws los siv txoj kev qhia cov dej sov rau hauv pwm txias Circuit Court kom hloov cov cua sov hauv pwm kab noj kom sai, kom tsis txhob ncua lub voj voog molding.
Txoj kev no tseem tuaj yeem txo cov kev ntxhov siab nyob hauv cov txheej txheem molding. Feem ntau, tshwj tsis yog rau polystyrene, ABS, thiab AS, pwm kub tuaj yeem tswj tau siab tshaj 100 degrees. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias yog tias pwm kub siab dhau lawm, nws tuaj yeem ua rau qhov chaw ntawm cov yas ua kom tsaus.
Tsis tas li ntawd, pwm tsis ua hauj lwm xws li me me demolding cov ces kaum, kev hloov pauv ntawm ntu ntu tuab, tuab tuab tuab heev, thiab me me los yog tam sim ntawd hloov ntawm lub rooj vag thiab khiav hla ntu, ntau lub zog shear hauv lub rooj vag system, turbulent ntws ntawm cov khoom molten, thiab cov pwm tsis zoo tuaj yeem cuam tshuam rau qhov zoo ntawm cov khoom yas, ua rau lub ntsej muag tsis zoo.
2. Kev tswj tsis raug ntawm kev tsim cov xwm txheej
Yog tias qhov kev txhaj tshuaj nrawm dhau los yog qeeb dhau, qhov kev txhaj tshuaj siab tsawg dhau, lub sijhawm tuav yog luv dhau, lub zog siab tsis txaus, lub ncoo tsis loj dhau, lub qhov nozzle me dhau los yog qhov kub thiab txias heev. Tsawg, qhov kev ua tau zoo ntawm cov fiber ntau reinforced yas muab tub lim yog qhov tsis zoo, qhov muab tub lim raug nthuav tawm lossis cov ntawv txhuas zoo li tus muab tub lim tsis muaj kev taw qhia, qhov kub ntawm cov khoom ntim qis dhau lawm, cov yaj plasticization tsis zoo, thiab cov khoom siv yog tsis txaus, tag nrho cov uas tuaj yeem ua rau tsis zoo ntawm qhov gloss ntawm cov khoom yas. Kev kho yuav tsum tau ua rau qhov xwm txheej tshwj xeeb.
Yog tias qhov chaw tsaus yog tsim nyob ze ntawm lub rooj vag lossis ntawm qhov sib txawv ntawm qhov sib txawv, nws tuaj yeem raug tshem tawm los ntawm kev txo qhov kev txhaj tshuaj, hloov lub rooj vag txoj hauj lwm, nthuav lub rooj vag, thiab ntxiv arc hloov ntawm qhov sib txawv ntawm qhov sib txawv.
Yog hais tias muaj ib txheej nyias ntawm milky dawb nyob rau saum npoo ntawm cov yas, qhov kev txhaj tshuaj ceev yuav raug txo kom tsim nyog. Yog hais tias lub ntsej muag gloss tsis zoo vim qhov kev ua haujlwm tsis zoo ntawm cov muab tub lim, cov khoom siv nrog cov dej ntws zoo lossis cov ntsia hlau uas muaj peev xwm sib xyaw yuav tsum tau siv.
3. Cov khoom siv molding tsis ua raws li cov kev cai siv
Cov dej noo los yog lwm yam tsis haum rau hauv cov ntaub ntawv molding yog siab dhau, ua rau cov khoom tsis sib haum xeeb los ntawm cov pwm kab noj hniav thiab cov khoom molten thaum lub sij hawm molding, ua rau cov khoom tsis zoo ntawm cov yas. Cov khoom siv raw yuav tsum tau qhuav ua ntej.
Lub decomposition thiab discoloration ntawm raw cov ntaub ntawv los yog colorants ua rau tsis zoo gloss. Cov ntaub ntawv kub resistant raw khoom thiab cov xim yuav tsum tau xaiv.
Qhov tsis zoo flowability ntawm cov ntaub ntawv raw ua rau xoob ntawm cov khoom yas thiab tsis zoo gloss. Nws raug nquahu kom hloov mus rau cov khoom siv nrog cov dej ntws zoo lossis ntxiv cov roj nplua nyeem uas tsim nyog thiab ua kom kub ua haujlwm.
Cov khoom siv raw yog sib xyaw nrog cov khoom sib txawv lossis cov khoom tsis sib xws. Cov ntaub ntawv tshiab yuav tsum tau siv los hloov.
