Epoxy engineering plastics feem ntau suav nrog epoxy molding compounds thiab epoxy laminates rau kev kub siab molding, nrog rau epoxy foams. Epoxy engineering plastics tseem tuaj yeem suav tias yog cov khoom siv dav dav epoxy sib xyaw. Epoxy cov ntaub ntawv feem ntau suav nrog epoxy iav fiber reinforced plastics (universal composite cov ntaub ntawv) thiab epoxy structural composite cov ntaub ntawv, xws li pultruded epoxy profiles, winding hollow rotary khoom thiab cov ntaub ntawv ua tau zoo. Epoxy composite cov ntaub ntawv yog cov khoom siv tseem ceeb thiab cov khoom siv hauv kev lag luam chemical, aviation, aerospace, tub rog thiab lwm yam khoom siv high-tech.
Ua ntej tshaj plaws, qhov zoo ntawm epoxy resin, epoxy resin hais ntawm no feem ntau yog hais txog bisphenol A epoxy resin.
1. Daim ntawv thov tus nqi ntawm epoxy resin ib leeg yog tsawg heev, thiab nws yuav tsum tau siv nrog kev kho tus neeg sawv cev kom muaj txiaj ntsig zoo.
2. Cov ntawv cog lus siab: Lub zog ntawm epoxy resin yog qhov siab tshaj plaws ntawm cov nplaum nplaum.
3. Lub curing shrinkage tus nqi yog me me, thiab tus nqi shrinkage ntawm epoxy resin nplaum yog qhov tsawg tshaj plaws ntawm cov nplaum, uas yog ib qho ntawm cov laj thawj rau kev kho siab thiab kev sib txuas ntawm epoxy resin adhesive.
4. Tshuaj tiv thaiv: Cov pab pawg ether, benzene nplhaib thiab aliphatic hydroxyl pawg hauv cov txheej txheem kho tsis yooj yim los ntawm cov kua qaub thiab alkali. Nws tuaj yeem siv tau ob xyoos hauv dej hiav txwv, roj av, roj av, 10% H2SO4, 10% HCl, 10% HAc, 10% NH3, 10% H3PO4 thiab 30% Na2CO3; thiab 50 feem pua H2SO4 thiab 10 feem pua HNO3 soaked nyob rau hauv chav tsev kub rau ib nrab xyoo; 10 feem pua NaOH (100 degree) soaked rau ib lub hlis, qhov kev ua tau zoo tseem tsis hloov.
5. Cov rwb thaiv tsev hluav taws xob zoo heev: qhov hluav taws xob tawg ntawm epoxy resin tuaj yeem ua tau ntau dua 35kV / hli
6. Cov txheej txheem kev ua tau zoo, cov khoom seem ruaj khov, ua haujlwm zoo thiab nqus dej tsawg.
