Qhov sib txawv tseem ceeb ntawm epoxy thiab fiberglass resin yog tias epoxy resins yog tsim los ntawm cov tshuaj tiv thaiv ntawm epichlorohydrin thiab bisphenol A whereas fiberglass resin yog tsim los ntawm kev sib xyaw ntawm cawv thiab organic acids.
Epoxy resins thiab fiberglass resins yog cov ntaub ntawv tseem ceeb uas tau txhim kho cov tshuaj lom neeg thiab lub cev.
Y Epoxy Resin yog dab tsi?
Epoxy resin yog chav kawm ntawm reactive pre-polymers thiab polymers uas muaj epoxide pawg. Cov ntaub ntawv cob qhia no tuaj yeem ua rau lawv tus kheej (ntawm catalytic homopolymerization) los yog nrog lwm cov co-reactants xws li polyfunctional amines, acids, phenols, alcohols thiab thiols los tsim kev sib txuas. Yog li ntawd, cov co-reactants no feem ntau hu ua hardeners lossis curatives. Ib yam li ntawd, txoj kev sib txuas sib txuas yog hu ua kev kho. Cov khoom ntawm cov txheej txheem kev sib txuas los yog kev kho 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 lub kaum os 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 cov khoom cua sov. 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 suav nrog, daim ntaub ntawv txheej, cov nplaum, cov khoom siv sib xyaw, kev siv cuab yeej siv, muaj txiaj ntsig zoo li kev sib txuas matrix nrog rau iav lossis carbon fiber ntau los tsim cov khoom sib xyaw nrog lub zog siab rau qhov hnyav, etc.
Fiberglass Resin yog dab tsi?
Fiberglass resin yog cov khoom siv hluavtaws tsim los ntawm kev sib xyaw ntawm cawv thiab organic acids. Peb tuaj yeem npaj cov resin no hauv ntau hom thiab. Tsis tas li ntawd, cov khoom no tuaj yeem hloov mus rau hauv gels, films, thiab kua. Qhov tseem ceeb, cov resins no yog cov ntaub ntawv polyester thiab muaj txiaj ntsig zoo rau ntau lub hom phiaj nrog rau nws siv los ua cov khoom siv casting, cov khoom ntim ntoo, cov nplaum, thiab rau kev kho nws pib. Qhov tseem ceeb tshaj, cov khoom siv no muaj cov khoom nplaum zoo heev thiab ua haujlwm ntev, uas ua rau nws muaj txiaj ntsig zoo rau cov nplaum ua ke nrog cov khoom sib txawv.
Feem ntau, peb ua cov qauv prefabricated siv fiberglass resin. Tsis tas li ntawd, ntau cov khoom siv kho kom zoo nkauj thiab cov qauv xws li cov kab thiab cov ceilings cuav kuj tau ua feem ntau siv fiberglass resins. Qhov no feem ntau yog vim cov khoom siv no yog huab cua tsis zoo thiab muaj zog heev.
Nyob rau hauv kev lag luam ntawm tsheb thiab cov khoom seem, fiberglass resins muaj txiaj ntsig zoo hauv kev tsim cov dav hlau me me thiab nruab nrab thiab cov neeg nqa khoom uas siv ntau cov khoom ua los ntawm cov khoom siv no. Fiberglass resin yog cov khoom siv hnyav uas ua rau nws yog cov khoom siv zoo heev rau kev siv dav hlau. Peb tuaj yeem ua lub cev panels ntawm lub tsheb, dav hlau thiab nkoj siv cov khoom siv no vim yog cov khoom qub. Txawm li cas los xij, tsis ntev los no, nws tau pom tias cov khoom siv resin no tuaj yeem nqus dej ntau heev uas ua rau nws tsis zoo rau kev siv hauv nkoj.
Qhov txawv ntawm Epoxy thiab Fiberglass Resin yog dab tsi?
Epoxy resins thiab fiberglass resins yog cov ntaub ntawv tseem ceeb uas tau txhim kho cov tshuaj lom neeg thiab lub cev. Qhov sib txawv tseem ceeb ntawm epoxy thiab fiberglass resin yog tias epoxy resins yog tsim los ntawm cov tshuaj tiv thaiv ntawm epichlorohydrin thiab bisphenol A, thaum fiberglass resin yog tsim los ntawm kev sib xyaw ntawm cawv thiab organic acids.
Hauv qab infographic tabulates ib sab ntawm qhov sib txawv ntawm epoxy thiab fiberglass resin.
Summary – Epoxy vs Fiberglass Resin
Epoxy resins thiab fiberglass resins yog cov ntaub ntawv tseem ceeb uas tau txhim kho cov tshuaj lom neeg thiab lub cev. Qhov sib txawv tseem ceeb ntawm epoxy thiab fiberglass resin yog tias epoxy resins yog tsim los ntawm cov tshuaj tiv thaiv ntawm epichlorohydrin thiab bisphenol A thaum fiberglass resin yog tsim los ntawm kev sib xyaw ntawm cawv thiab organic acids.
