Qhov sib txawv tseem ceeb ntawm epoxy resin thiab UV resin yog tias epoxy resin muaj lub zog ua haujlwm siab nrog kub ua haujlwm thiab khawb tsis kam, qhov UV resins tsis tshua muaj zog thiab tsis muaj cua sov los yog khawb resistant.
A resin yog ib yam khoom nplaum nplaum nplaum, insoluble hauv dej, exuded los ntawm qee cov ntoo thiab lwm yam nroj tsuag. Epoxy resin thiab UV resin yog ob hom khoom siv.
Y Epoxy Resin yog dab tsi?
Epoxy resins yog ib hom reactive pre-polymers thiab polymers uas muaj epoxide pawg. Cov khoom no tuaj yeem hnov qab nrog lawv tus kheej (ntawm catalytic homopolymerization) lossis nrog lwm cov co-reactants xws li polyfunctional amines, acids, phenols, alcohols, thiab thiols los tsim cov kab sib txuas. Peb feem ntau hu cov co-reactants ua hardeners los yog curatives. Tsis tas li ntawd, txoj kev sib txuas sib txuas peb siv ntawm no yog kho. Cov khoom ntawm qhov kev sib txuas los yog kho cov txheej txheem no yog cov khoom siv thermosetting polymer uas muaj cov khoom siv zoo thiab cov thermal thiab tshuaj tiv thaiv siab.
Nyob rau hauv cov txheej txheem kho ntawm epoxy resin, muaj ntau ntau cov tshuaj uas peb tuaj yeem siv ua cov tshuaj tua kab mob. Qee qhov piv txwv suav nrog amines, imidazoles, anhydrides, thiab cov tshuaj photosensitive. Feem ntau, cov khoom siv tsis zoo epoxy resin muaj cov khoom siv tsis zoo, tshuaj lom neeg, thiab kub-resistant zog. Kev kho ntawm epoxy resins yog cov tshuaj tiv thaiv exothermic. Qee zaum, cov tshuaj tiv thaiv no ua rau muaj cua sov txaus uas tuaj yeem ua rau thermal degradation ntawm cov resin yog tias tsis tswj tau.
Muaj ntau yam kev siv ntawm epoxy resins, nrog rau cov ntawv txheej, cov nplaum, cov khoom siv sib xyaw, kev siv cuab yeej siv, kev sib txuas cov matrix nrog rau iav lossis carbon fiber fabrics los tsim cov khoom sib xyaw nrog cov yam ntxwv siab-rau-hnyav, thiab lwm yam.
YUV Resin yog dab tsi?
UV resin yog ib hom resin uas muaj nyob rau hauv pab pawg ntawm cov khoom siv hluavtaws thiab kho los ntawm lub zog ntawm lub hnub lossis UV cov khoom siv. Feem ntau, UV reins kho tag nrho hauv ob peb feeb, thiab peb tuaj yeem siv lawv rau kev sib khi, kev sib txuas, thiab cov khoom siv txheej. Cov khoom siv no yog siv rau hauv ib txheej nyias, thiab nws tseem ntub kom txog thaum nws raug UV teeb. Lub teeb no tuaj yeem yog hnub ci lossis hauv qab lub teeb ntawm UV teeb.
Ntxiv mus, UV resin yog qhov tseem ceeb hauv kev sib khi collages thiab embedded khoom nyob rau hauv hlau bezels los cam khwb cia cov duab nyob rau hauv pwm thiab kuj tsim ib tug enameled saib nyob rau hauv cov hniav nyiaj hniav kub. Feem ntau, UV resin yog ua los ntawm monomers, oligomers, photopolymerization, pib, thiab lwm yam additives. Thaum nws raug UV teeb, lub photoinitiator nyhav dhau los ua cov tshuaj tiv thaiv tshuaj, tso cai rau nws ua kom muaj kev ywj pheej oligomers thiab monomers rau hauv cov saw hlau ntau dua. Peb hu cov chains polymers. Yog li ntawd, nyob rau hauv luv luv, UV resin yog ib yam khoom uas polymerizes thiab kho nyob rau hauv ib tug luv luv lub sij hawm los ntawm lub zog ntawm UV rays emitted los ntawm ib tug UV irradiation ntaus ntawv.
Qhov txawv ntawm Epoxy Resin thiab UV Resin yog dab tsi?
Qhov sib txawv tseem ceeb ntawm epoxy resin thiab UV resin yog tias epoxy resin muaj lub zog ua haujlwm siab nrog kub ua haujlwm thiab khawb tsis kam, qhov UV resins tsis tshua muaj zog thiab tsis kub lossis khawb resistant.
Cov hauv qab no qhia txog qhov sib txawv ntawm epoxy resin thiab UV resin nyob rau hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary - Epoxy Resin vs UV Resin
Epoxy resins yog ib hom reactive pre-polymers thiab polymers uas muaj epoxide pawg, thaum UV resin yog ib hom hluavtaws cob uas kho tau los ntawm lub zog ntawm lub hnub lossis UV khoom. Qhov sib txawv tseem ceeb ntawm epoxy resin thiab UV resin yog tias epoxy resin muaj qhov ua haujlwm siab nrog kev ua haujlwm kub thiab khawb, qhov UV resins tsis tshua muaj zog thiab tsis kub lossis khawb resistant.
