Kev nkag siab zoo ntawm UV resin

UV resin, tseem hu ua UV oligomer, yog ib yam khoom tseem ceeb tsim los ntawm UV zaj duab xis Z. nyob rau hauv cov xwm txheej ntawm UV irradiation, lawv tau hla mus rau hauv cov qauv sib txawv nrog qhov sib txawv los ntawm kev ua kom cov photoinitiator molecules, kom cov UV txheej muaj ntau yam. lub cev thiab txhua yam khoom, xws li siab hardness, siab softness, zoo substrate adhesion, tsis tshua muaj cov khoom daj, huab cua tsis kam, thiab lwm yam, UV txheej engineers feem ntau tshuaj xyuas cov UV oligomers tsim nyog raws li cov yeeb yaj kiab uas lawv xav tau.

Feem ntau siv UV oligomers yog qhov txawv ntawm cov qauv molecular.Peb tuaj yeem sau lawv rau hauv: epoxy acrylate oligomer, polyurethane acrylate oligomer, amino acrylate oligomer, polyester acrylate oligomer, ntshiab acrylate oligomer thiab lwm yam acrylate oligomers nrog cov qauv tshwj xeeb.Los ntawm lub hauv paus ntsiab lus ntawm kev faib cov qauv, peb piav qhia txoj kev xav thiab piav qhia luv luv txog kev ua tau zoo ntawm cov khoom siv UV oligomer, nrhiav lub hauv paus theoretical los txhawb lawv cov kev ua tau zoo, thiab nkag siab tob txog cov khoom muaj feem xyuam.

Nws yuav tsum tau taw qhia tias UV oligomers kuj tseem tuaj yeem muab faib ua ntau yam khoom nrog cov kev ua haujlwm sib txawv hauv tib yam qauv.Nrog ntau tus lej ntawm cov pab pawg ua haujlwm sib txawv, qhov compactness ntawm lub network qauv tsim yuav tsis sib haum.Cov pab pawg ua haujlwm xa mus rau cov pab pawg ua haujlwm hauv cov resin uas tuaj yeem cuam tshuam cov tshuaj tiv thaiv kev sib txuas.Cov pab pawg ua haujlwm ntau dua nyob rau hauv ib lub molecule, qhov denser zaj duab xis tsim tom qab kho, thiab qhov yooj yim dua nws yog kom tau cov xim zaj duab xis nrog ntau dua hardness.Txawm li cas los xij, nyob rau tib lub sijhawm, vim qhov nce ntawm cov pawg sib txuas sib txuas, lub zog shrinkage tsim nyob rau hauv cov txheej txheem ntawm oligomer curing kuj yuav nce, Qhov no yuav yooj yim ua rau muaj kev cuam tshuam ntawm kev ntxhov siab tso tawm lossis txo qis ntawm adhesion thaum lub sij hawm. txheej txheem ziab ntawm txheej.Tom qab teeb tsa cov khoom sib txawv ntawm cov txheej txheem, UV txheej txheej txheej yuav tsum xaiv cov khoom tsim nyog rau kev sib txuam raws li oligomer cov khoom ntawm cov qauv sib txawv thiab cov pab pawg ua haujlwm, kom tau txais cov txheej txheem sib npaug thiab ua tiav cov qauv ntawm UV txheej txheej. .

Yog tias qhov viscosity ntawm UV resin siab dhau lawm, nws tsis tsim nyog ntxiv ntau dhau rau qee cov ntsiab lus thov uas xav tau UV kua nplaum nrog cov dej zoo.Lub refractive index ntawm cov resin yog tsawg heev.Nyob rau ntawm qhov chaw ntawm kev siv optical lens, lub teeb transmittance tsis txaus, yog li nws tsis yog siv raws li kev siv.Raws li rau lub zog viscosity, cov resin muaj - Oh feem ntau muaj adhesion zoo rau iav, yog li kuv yuav tsis piav qhia ntau dhau ntawm no.UV resin yog matrix resin ntawm UV kua nplaum.Nws yog compounded nrog photoinitiator, nquag diluent thiab ntau yam additives los ua UV kua nplaum.Nyob rau hauv lub synthesis theem, sib txawv synthesis txheej txheem los yog kev xaiv ntawm monomers ua rau lub uncertainty ntawm resin.Lub viscosity, refractive index thiab applicability ntawm resin rau ntau yam ntaub ntawv yuav tsum tau xav txog.

Lub ntsiab daim ntawv thov teb ntawm UV resin: UV txheej, UV number case, UV kua nplaum, thiab lwm yam ntawm lawv, Z yog dav siv nyob rau hauv UV txheej, nrog rau cov nram qab no hom ntawm UV dej-raws li txheej, UV hmoov txheej, UV tawv txheej, UV optical fiber txheej, UV hlau txheej, UV ntawv polishing txheej, UV yas txheej thiab UV ntoo txheej.

Qhov zoo ntawm UV resin photosensitive resin yog cov khoom qub thiab tshiab.Piv nrog rau cov khoom siv kho kom zoo, cov ntaub ntawv kho lub teeb muaj qhov zoo hauv qab no: kev kho sai sai, kho hauv ob peb vib nas this, thiab tuaj yeem siv rau hauv cov xwm txheej uas yuav tsum tau kho tam sim.Cov khoom tsis muaj kuab tshuaj tuaj yeem npaj tau yam tsis muaj cua sov.Kev siv cov kuab tshuaj yuav cuam tshuam ntau yam teeb meem ib puag ncig thiab cov txheej txheem pom zoo.Yog li ntawd, txhua qhov kev lag luam kev lag luam sim txo qis kev siv cov kuab tshuaj.Qhov no muaj txiaj ntsig zoo rau qee qhov tsis muaj cua sov resistant yas, optical thiab hluav taws xob qhov chaw;Nws tuaj yeem paub txog kev ua haujlwm tsis siv neeg thiab ruaj khov, txhim kho qib ntawm automation ntawm ntau lawm, txhawm rau txhim kho kev tsim khoom thiab cov txiaj ntsig kev lag luam.Photosensitive resin yog siv nyob rau hauv kev lag luam tawm ntawm 3D luam ntawv, uas yog nyiam thiab muaj nuj nqis los ntawm kev lag luam vim nws cov yam ntxwv zoo heev.Kaft thawj cov kua photosensitive resin nyob rau hauv Tuam Tshoj yog siv los ua 3D luam ntawv consumables, uas yog haum rau high-precision lub teeb curing 3D printing thiab SLA ceev prototyping system.
