(1) High mechanical zog. Epoxy resin muaj zog cohesion thiab ntom molecular qauv, yog li nws cov khoom siv kho tshuab siab dua li cov hom phiaj thermosetting resins xws li phenolic resin thiab unsaturated polyester.
(2) Cov txheej txheej ntawm cov yeeb nkab yas-coated hluav taws siv epoxy resin, uas muaj zog adhesion. Lub epoxy resin curing system muaj cov pab pawg epoxy uas muaj zog heev, pawg hydroxyl, thiab pawg polar xws li ether bonds, amine bonds, thiab ester bonds, uas tso cai rau cov khoom kho epoxy nrog cov pawg polar xws li hlau, ceramics, iav, pob zeb, thiab ntoo. . khoom nrog zoo adhesion.
(3) Kev kho me me shrinkage. Feem ntau 1 mus rau 2 feem pua. Nws yog ib qho ntawm cov ntau yam nrog qhov tsawg tshaj plaws curing shrinkage ntawm thermosetting resins (phenolic resin yog 8 feem pua rau 10 feem pua; unsaturated polyester resin yog 4 feem pua rau 6 feem pua ; silicone resin yog 4 feem pua rau 8 feem pua). Cov coefficient ntawm linear expansion kuj me me, feem ntau 6 × 10-5/degree . Yog li lub ntim hloov me ntsis tom qab kho.
(4) Kev ua haujlwm zoo. Epoxy resin yeej tsis tsim cov tsis muaj molecular volatiles thaum kho, yog li nws tuaj yeem ua kom tsis tshua muaj siab molding lossis tiv tauj siab molding. Nws tuaj yeem siv nrog ntau yam tshuaj tua kab mob los tsim cov txheej txheem ib puag ncig xws li hnyav-dawb, siab-khoom, hmoov txheej thiab dej-raws li txheej.
(5) Cov rwb thaiv tsev hluav taws xob zoo heev. Epoxy resins yog thermosetting resins nrog zoo antistatic zog.
(6) Zoo stability thiab zoo heev tshuaj tiv thaiv. Epoxy resin uas tsis muaj impurities xws li alkali thiab ntsev tsis yooj yim rau deteriorate. Tsuav nws khaws cia kom zoo (sau, tiv thaiv los ntawm ya raws thiab kub), nws lub sijhawm cia yog 1 xyoos. Tom qab hnub tas sij hawm, nws tseem tuaj yeem siv tau yog tias nws dhau qhov kev tshuaj xyuas. Cov khoom siv kho mob epoxy muaj kev ruaj ntseg zoo heev. Nws corrosion kuj mus rau ntau yam xov xwm xws li alkali, acid thiab ntsev yog zoo dua li ntawm thermosetting resins xws li unsaturated polyester resin thiab phenolic resin. Yog li ntawd, epoxy resin yog dav siv los tiv thaiv corrosion primer, thiab vim hais tias cov epoxy resin kho cov khoom muaj ib tug peb-dimensional network qauv thiab yog resistant rau impregnation ntawm roj, thiab lwm yam, nws yog dav siv nyob rau hauv roj tso tsheb hlau luam, roj tankers, thiab ib qho roj tank linings ntawm aircraft.
(7) Lub tshav kub tsis kam ntawm cov khoom kho epoxy feem ntau yog 80 txog 100 degree. Lub tshav kub-resistant ntau yam ntawm epoxy resins tuaj yeem ncav cuag 200 degree lossis siab dua.
