Gelation yog hais txog qhov thickening lossis caking ntawm UV resin los yog txheej ntawm qhov ntsuas kub thiab lub sijhawm.
Lub ntsiab yog vim li cas rau gelatinization ntawm UV resin los yog txheej yog raws li nram no:
1. Tshaj li lub txee lub neej, lub txee lub neej ntawm UV resin nyob rau hauv zoo cia yuav tsum tsis pub tshaj rau lub hlis.Tab sis Z zoo tuaj yeem siv tau hauv peb lub hlis.
2. UV resin yuav tsum muab khaws cia rau hauv cov thawv yas lossis cov thawv hlau coated nrog cov yas.Hlau ions yuav txo tau lub zog ua kom muaj zog ntawm ob daim ntawv cog lus nyob rau hauv UV resin thiab pib polymerization, ua rau resin gelation.Yog li ntawd, yog hais tias cov yas plating txheej nyob rau hauv lub yas plating chim yog puas, lub liab qab hlau txheej yuav ua rau resin gelation.
3. Tsis tshua muaj cia kub (hauv qab 0 ℃) yuav precipitate lub polymerization inhibitor nyob rau hauv cov xim zaj duab xis, ua rau resin tus kheej polymerization thiab resin gelation.
4. UV resin yuav tsum nruj me ntsis tiv thaiv los ntawm tshav ntuj ncaj qha thaum khaws cia.Txwv tsis pub, nws yog ib qho yooj yim ua rau resin gelation.
5. Yog hais tias lub thoob puv dhau, tsis muaj oxygen txaus los tiv thaiv polymerization, uas yuav ua rau resin gelation.
Kev ceev faj rau gelation:
1. Lub viscosity ntawm cov resin tsis diluting monomer yog siab heev.Qee cov neeg siv yuav yuam kev xav tias cov resin tau gelatinized.Qhov tseeb, nws yog ib qho yooj yim los xyuas seb cov resin yog gelatinized tom qab cua sov.Cov resin tsis muaj gelatinization yuav muaj fluidity zoo tom qab cua sov.
2. Raws li kev siv UV resin, cov txheej txheem kev tshawb nrhiav thiab ntsuas ntawm UV txheej zaj duab xis yog tib yam li lwm cov txheej txheej, uas sib txawv nrog cov ntawv thov tshwj xeeb.Yuav muaj ntau yam teeb meem hauv daim ntawv thov ntawm UV txheej.Tsuas yog gelatinization thaum lub sij hawm cia yog ze ze rau UV resin nws tus kheej, thiab lwm yam teeb meem yuav daws tau los ntawm kev kho UV txheej formula.Raws li uvpaint yog tsim los ntawm ntau yam khoom, nws kuj tseem cuam tshuam los ntawm lub teeb qhov chaw illumination nrug thiab lub sij hawm illumination, thiab nws cov yeeb yaj kiab ua tau zoo yog qhov tshwm sim ntawm kev ua tiav ntawm ntau yam.Rau tib lub mis, tam sim ntawd hloov tib yam resin.Vim qhov sib txawv ntawm cov resins los ntawm ntau lub tuam txhab, kev ua haujlwm ntawm cov yeeb yaj kiab yuav raug hloov, thiab cov qauv yuav tsum tau hloov kho.Txawm li cas los xij, tsuav yog cov resin tsis gelatinized lossis gelatinized hauv cov xim npaj, qhov kev ua tau zoo ntawm cov yeeb yaj kiab tuaj yeem hloov kho los ntawm cov qauv.
3. Muaj ntau yam laj thawj rau gelatinization ntawm UV xim, uas tsis yog tsuas yog cuam tshuam nrog cov resin.Ua ntej, peb yuav tsum saib seb nws yog tshwm sim los ntawm kev cia khoom tsis raug.Vim yog qhov sib ntxiv ntawm photosensitizer hauv UV txheej, nws cov khoom khaws cia yog nruj dua li cov UV resin.Nws yog ib qho tsim nyog yuav tsum khaws cia hauv qhov tsaus ntuj kom tsis txhob pom qhov kaj.Qhov thib ob, cov photosensitizer xaiv tsis zoo, thiab txawm tias nws khaws cia hauv qhov tsaus ntuj, nws yuav maj mam decompose thiab ua rau gelation ntawm cov txheej txheem kho.
4. Qhov zoo ntawm monomer kuj yog ib qho tseem ceeb cuam tshuam rau kev ruaj ntseg cia.
