Qhov sib txawv tseem ceeb ntawm phenolic resin thiab epoxy resin yog tias phenolic resins qhia cov qib qis ntawm kev ua haujlwm kub, qhov epoxy resins qhia qhov kub siab ua haujlwm.
Xaiv cov khoom countertop kom raug rau daim ntawv thov kev sim yog qhov tseem ceeb heev vim tias cov chaw hauv chav kuaj tau siv tsis tu ncua, thiab qee zaus lawv muaj kev kub ntxhov lossis tshuaj lom neeg. Phenolic resins thiab epoxy resins yog ob hom khoom peb siv tau rau lub hom phiaj no.
YPhenolic Resin yog dab tsi?
Phenolic resins yog ib chav kawm ntawm hluavtaws thermosetting cob. Cov khoom siv tau tsim los ntawm Dr Leo Baekeland hauv xyoo 1907. Phenolic resins yog Ameslikas hu ua Bakelite. Muaj ob hom phenolic resins li novalocs thiab resoles. Ob hom no ruaj khov ntawm qhov kub siab heev. Feem ntau, cov khoom no muaj xim tsaus thiab muaj qhov ua tau zoo heev.
Phenolic resins muaj cov ntawv thov sib txawv xws li kev tsim khoom hauv Circuit Court, tsim cov khoom pwm xws li cov khoom siv billiard, chav kuaj countertops, coatings, adhesives, thiab lwm yam. siv tsis tu ncua thiab tu ntau zaus. Ntxiv mus, nws muaj li ntawm 4 mus rau 6 lub lis piam ntawm lub sij hawm coj los yog lub sij hawm. Cov ntaub ntawv no muaj peev xwm tiv taus noo noo ib yam.
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 kev 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 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.
Daim duab 01: Ua kua Epoxy Resin
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 epoxy resin tsis tau kho muaj cov khoom siv tsis zoo, tshuaj lom neeg thiab cov khoom siv 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 ntawv thov 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.
Dab tsi yog qhov txawv ntawm Phenolic Resin thiab Epoxy Resin?
Phenolic resins thiab epoxy resins muaj cov khoom sib txawv ntawm ib leeg. Ntawm cov no, qhov sib txawv tseem ceeb ntawm phenolic resin thiab epoxy resin yog tias phenolic resins qhia qis qis ntawm cov cua sov, thaum epoxy resins qhia tau hais tias muaj kev kub ntxhov siab. Tsis tas li ntawd, phenolic resins tsis tshua kim dua li epoxy resins.
Cov lus qhia hauv qab no qhia qhov sib txawv ntawm phenolic resin thiab epoxy resin nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Phenolic Resin vs Epoxy Resin
Nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom raug rau countertops hauv chav kuaj. Phenolic resins thiab epoxy resins yog ob hom ntaub ntawv uas peb tuaj yeem siv rau lub hom phiaj no. Qhov sib txawv tseem ceeb ntawm phenolic resin thiab epoxy resin yog tias phenolic resins qhia qis qis ntawm cov cua sov, qhov epoxy resins qhia tau hais tias muaj kev kub ntxhov siab.
