Cov khoom zoo heev ntawm epoxy resin ua rau nws ua lub luag haujlwm tseem ceeb hauv kev sib txuas, kho thiab kho qhov chaw ntawm cov khoom xws li pob zeb thiab hlau. Txawm li cas los xij, nrog kev siv epoxy resin nce ntxiv, qhov teeb meem ntawm kev pov tseg pov tseg tau maj mam nyiam. Yog tias epoxy resin pov tseg tsis raug kho kom raug, nws yuav ua rau muaj kuab paug rau ib puag ncig. Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los tshawb nrhiav cov kev kho ib puag ncig zoo. Kab lus no yuav tham txog tiam, txoj kev kho mob thiab kev kho tus phooj ywg ib puag ncig ntawm epoxy resin pov tseg.
Cov yam ntxwv thiab kev siv ntawm Epoxy Resin
Epoxy resin (Epoxy Resin) yog ib qho polymer compound tsim los ntawm cov tshuaj tiv thaiv ntawm epoxy compounds thiab curing agents. Nws muaj kev ruaj ntseg zoo heev, corrosion kuj, hnav tsis kam thiab adhesion zoo. Nws yog feem ntau siv rau hauv cov coatings, adhesives, composite cov ntaub ntawv, hluav taws xob tivthaiv ntim, pob zeb bonding thiab lwm yam teb. Epoxy resin yog qhov tseem ceeb tshwj xeeb hauv kev lag luam pob zeb. Nws tuaj yeem siv los txhim kho lub hardness, permeability kuj, hnav tsis kam thiab zoo nkauj ntawm pob zeb.
Vim yog daim ntawv thov dav ntawm epoxy resin, cov khib nyiab epoxy resin tsim thaum lub sij hawm kho pob zeb tau dhau los ua qhov teeb meem ib puag ncig uas tsis tuaj yeem tsis quav ntsej. Cov qauv molecular siab ntawm epoxy resin nws tus kheej ua rau nws nyuaj rau degrade nyob rau hauv ib puag ncig ntuj. Yog tias nws raug muab pov tseg lossis tuav tsis raug, nws yuav ua rau muaj kuab paug rau cov av, dej thiab huab cua.
Qhov chaw tseem ceeb ntawm epoxy resin pov tseg
Pov tseg hauv cov txheej txheem ntau lawm
Hauv cov txheej txheem tsim khoom ntawm epoxy resin, muaj qee qhov pov tseg tsim tawm, suav nrog kev ua tsis tiav epoxy resin, kho cov residues, thiab cov kua khib nyiab tom qab ntxuav cov khoom. Yog tias cov khib nyiab no tsis raug kho, kev tso tawm ncaj qha yuav ua rau lub nra hnyav rau ib puag ncig.
