Yuav Ua Li Cas Tswj Cov Chromatic Aberration ntawm Txhaj Moulded Khoom

Chromatic aberration yog ib qho tsis xws luag hauv kev txhaj tshuaj molding. Nws tsis yog qhov tsis tshua muaj qhov sib txawv ntawm cov xim sib txawv ntawm qhov sib txuam ua rau kev tsis lees paub ntawm lub tshuab txhaj tshuaj molding hauv cov khoom siv. Muaj ntau yam cuam tshuam rau chromatic aberration, xws li resin, masterbatch, masterbatch sib xyaw nrog raw cov ntaub ntawv, txheej txheem txhaj tshuaj molding, txhaj tshuaj molding tshuab, pwm thiab lwm yam. Vim muaj ntau yam kev koom tes, chromatic aberration tswj thev naus laus zis kuj tau lees paub tias yog ib qho ntawm cov thev naus laus zis nyuaj rau tus tswv hauv kev txhaj tshuaj molding. Hauv cov txheej txheem tsim khoom tiag tiag, peb feem ntau pib los ntawm tsib yam nram qab no los tswj cov xim sib txawv.

1. tshem tawm cov kev cuam tshuam ntawm kev txhaj tshuaj molding tshuab thiab pwm yam.

Txhawm rau xaiv lub tshuab txhaj tshuaj molding nrog tib lub peev xwm raws li cov khoom tseem ceeb ntawm kev txhaj tshuaj molding, yog tias lub tshuab txhaj tshuaj molding khoom siv lub kaum sab xis tuag thiab lwm yam teeb meem, nws yog qhov zoo tshaj los hloov cov khoom siv. Rau qhov sib txawv ntawm cov xim uas tshwm sim los ntawm cov pwm pouring system thiab cov pa groove, nws tuaj yeem daws tau los ntawm qhov sib thooj ntawm cov pwm tu pwm. Peb yuav tsum xub daws qhov teeb meem ntawm kev txhaj tshuaj molding tshuab thiab pwm ua ntej kev teeb tsa ntau lawm thiaj li txo qhov nyuaj ntawm qhov teeb meem.

2. tshem tawm kev cuam tshuam ntawm resin thiab xim masterbatch.

Tswj cov ntaub ntawv raw yog tus yuam sij los daws qhov chromatic aberration kiag li. Yog li ntawd, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov khoom ntawm lub teeb xim, peb tsis tuaj yeem tsis quav ntsej qhov sib txawv thermal stability ntawm raw resin ntawm cov khoom xim fluctuation tshwm sim los ntawm kev cuam tshuam pom tseeb. Txij li feem ntau cov tuam txhab txhaj tshuaj molding tsis tsim cov yas masterbatches lossis xim masterbatches lawv tus kheej, kev saib xyuas tuaj yeem tsom mus rau kev tswj hwm ntau lawm thiab kev tshuaj xyuas cov khoom siv raw. Qhov ntawd yog txhawm rau ntxiv dag zog rau kev tshuaj xyuas cov khoom siv raw khoom warehousing.

Cov khoom qub yog tsim nrog tib lub chaw tsim khoom, tib lub npe tswv batch thiab master batch kom deb li deb tau; rau tus tswv batch, peb yuav tsum tau ua qhov chaw kuaj xyuas thiab kuaj xim ua ntej ntau lawm, ob qho tib si nrog cov ntawv pov thawj dhau los, tab sis kuj nyob rau hauv qhov kev sib piv no, yog tias qhov sib txawv xim tsis loj, tuaj yeem suav tias tsim nyog, raws li batch master batch muaj xim txawv me ntsis. , tuaj yeem ua tus tswv xim hnyav. Cov sib tov tshiab yog siv los txo cov chromatic aberration tshwm sim los ntawm kev sib xyaw ntawm cov xim tsis sib xws. Nyob rau tib lub sijhawm, peb kuj yuav tsum tau tsom mus rau kev ntsuam xyuas thermal stability ntawm raw resins, masterbatches, rau thermal stability tsis zoo, peb xav kom manufacturers hloov.

3. tshem tawm qhov cuam tshuam ntawm kev sib xyaw tsis sib xws ntawm masterbatch thiab masterbatch.

Sib tov cov yas masterbatch nrog cov xim masterbatch kuj yuav ua rau cov khoom xim hloov tau. Thaum masterbatch thiab masterbatch yog mechanically sib tov sib npaug thiab pub rau hauv hopper los ntawm cov khoom siv downdraft, masterbatch yog yooj yim adsorbed rau ntawm phab ntsa hopper vim yog hluav taws xob zoo li qub. Qhov no yuav ua rau muaj kev hloov pauv ntawm tus lej masterbatch hauv kev txhaj tshuaj molding voj voog, ua rau chromatic aberration.

Qhov teeb meem no tuaj yeem daws tau los ntawm kev nqus cov khoom siv raw tom qab hopper thiab phau ntawv agitation. Ntau lub tuam txhab tam sim no siv feeders ntxiv cov xim masterbatch, uas txuag tau ntau tus neeg ua haujlwm thiab muab kev pabcuam zoo rau kev tswj cov xim sib txawv, tab sis ntau lub tuam txhab vim siv tsis raug, cov txiaj ntsig feem ntau tsis txaus siab.

Tus nqi ntawm Xim Masterbatch ntxiv rau lub feeder ntawm qhov ceev ceev yog nyob ntawm lub sij hawm plasticizing, thiab lub sij hawm plasticizing nws tus kheej yog fluctuating, tej zaum fluctuating los yog kuj loj, yog li kom ntseeg tau tias ib tug tas mus li tus nqi ntawm cov pub, feeder lub sij hawm yuav tsum tau kho, thiab lub sijhawm teeb tsa tsawg dua li lub sijhawm plasticizing yam tsawg kawg nkaus. Thaum siv lub feeder, nws yuav tsum tau muab sau tseg tias qhov hluav taws xob ntawm lub feeder yog me me. Tom qab ib lub sij hawm ntawm kev siv, nws yuav ua rau noj tsis raug thiab txawm ua rau lub feeder nres. Yog li ntawd, yuav tsum tau ntxuav tsis tu ncua.

4. txo qhov cuam tshuam ntawm lub chim kub ntawm chromatic aberration.

Hauv kev tsim khoom, nws tau ntsib ntau zaus tias qhov kub ntawm lub thoob hloov pauv ntau heev vim qhov kev puas tsuaj thiab tsis ua haujlwm ntawm lub nplhaib cua sov lossis kev tswj tsis tau ntawm cov cua sov. Nws yog ib qho yooj yim los txiav txim cov xim sib txawv los ntawm qhov laj thawj zoo li no. Feem ntau, cov xim sib txawv tshwm sim los ntawm qhov tsis ua haujlwm ntawm lub nplhaib cua sov yuav nrog rau qhov tshwm sim tsis zoo ntawm plasticization. Qhov tawm-ntawm-tswj ntev-kub ntawm cov cua sov tswj qhov feem ntau nrog cov khoom siv roj, discoloration loj thiab txawm coking phenomenon. Yog li ntawd, nws yog ib qho tsim nyog los tshuaj xyuas qhov cua sov ntau zaus hauv kev tsim khoom thiab hloov cov cua sov kom raws sij hawm thaum pom tias qhov cua sov puas los yog tsis muaj kev tswj xyuas kom txo tau qhov tshwm sim ntawm cov xim sib txawv.

5.txo qhov cuam tshuam ntawm kev txhaj tshuaj molding txheej txheem hloov.

Kev txhaj tshuaj kub, rov qab siab, lub sijhawm txhaj tshuaj thiab tus nqi ntawm chromophore yuav tsum tsis txhob hloov ntau npaum li qhov ua tau thaum cov txheej txheem txhaj tshuaj raug kho vim tsis yog chromophore. Raws li qhov ua tau kom tsis txhob siv cov kev txhaj tshuaj siab ceev, siab rov qab siab thiab lwm yam muaj zog shear nyhuv tshwm sim los ntawm kev txhaj tshuaj molding txheej txheem, los tiv thaiv lub zos overheating los yog thermal decomposition thiab lwm yam tshwm sim los ntawm cov xim sib txawv. Ua tib zoo tswj qhov kub ntawm txhua qhov cua sov ntawm lub thoob, tshwj xeeb tshaj yog lub nozzle thiab cua sov qhov ze ntawm lub nozzle.
