Tom qab kev sim, cov qauv tau muab tso rau hauv ib puag ncig nrog qhov kub ntawm (20 ± 5) ℃ rau 24 teev.Cov txheej txheej sab hauv raug kuaj xyuas thiab kev kuaj adhesion tau ua raws li cov kev cai ntawm 6.4.Cov txiaj ntsig kev xeem yuav tsum ua raws li cov cai ntawm 5.14.
Sov dej aging test
Qhov loj thiab ntev ntawm cov yeeb nkab seem qauv yog hais txog 100 mm.Qhov chaw raug ntawm ob qho kawg ntawm cov yeeb nkab seem yuav tsum tau kho nrog anticorrosion.Cov kav dej yuav tsum tau muab tso rau hauv dej distilled ntawm (70 ± 2) ℃ rau 30 hnub.
Features txheej txheem cej luam editor tshaj tawm
(1) High mechanical zog.Epoxy resin muaj zog cohesion thiab compact molecular qauv, yog li nws cov khoom siv kho tshuab siab tshaj phenolic resin thiab unsaturated polyester thiab lwm yam universal thermosetting resins.
(2) Yas hluav taws yeeb nkab txheej siv epoxy resin, muaj zog adhesion.Cov txheej txheem kho ntawm epoxy resin muaj cov pab pawg epoxide uas muaj zog heev, pawg hydroxyl, ether daim ntawv cog lus, amine daim ntawv cog lus, ester daim ntawv cog lus thiab lwm pawg polar, muab cov khoom siv kho mob epoxy nrog zoo adhesion rau hlau, ceramic, iav, pob zeb, ntoo thiab lwm yam polar substrates. .
(3) curing shrinkage tus nqi yog me me.Feem ntau 1% ~ 2%.Nws yog ib qho ntawm ntau hom nrog qhov tsawg tshaj plaws curing shrinkage nyob rau hauv thermosetting resin (phenolic resin yog 8% ~ 10%; Unsaturated polyester resin yog 4% ~ 6%; Silicone resin 4% ~ 8%).Linear expansion coefficient kuj tsawg heev, feem ntau 6 × 10-5 / ℃.Yog li lub ntim hloov me ntsis tom qab kho.
(4) Kev siv tshuab zoo.Epoxy resin curing yeej tsis tsim cov tsis tshua muaj molecular volatiles, yog li tuaj yeem ua kom tsis tshua muaj siab molding lossis hu rau nias molding.Nws tuaj yeem koom tes nrog txhua yam kev kho tus neeg sawv cev los tsim cov kuab tshuaj tsis muaj zog, cov khoom siv siab, hmoov txheej thiab dej-raws li txheej thiab lwm yam txheej txheej hauv ib puag ncig.
(5) Cov rwb thaiv tsev hluav taws xob zoo heev.Epoxy resin yog ib qho thermosetting resin nrog zoo antistatic zog.
(6) Zoo stability, zoo heev tiv taus tshuaj.Epoxy resin tsis muaj alkali, ntsev thiab lwm yam impurities tsis yooj yim rau deteriorate.Tsuav nws khaws cia kom zoo (sau, tsis cuam tshuam los ntawm ya raws, tsis kub), nws lub sijhawm cia yog 1 xyoos.Nws tseem tuaj yeem siv tau yog tias nws tsim nyog tom qab tas sijhawm.Epoxy kho cov ntaub ntawv muaj kev ruaj ntseg zoo heev.Nws corrosion kuj ntawm alkali, acid, ntsev thiab lwm yam xov xwm yog zoo dua unsaturated polyester resin, phenolic resin thiab lwm yam thermosetting resin.Yog li ntawd, epoxy resin yog dav siv los ua anticorrosive primer, thiab vim hais tias epoxy resin curing khoom yog peb-dimensional network qauv, thiab tuaj yeem tiv taus cov roj impregnation, thiab lwm yam., ntau daim ntawv thov hauv roj tank, roj tanker, aircraft, sab hauv phab ntsa hauv ob sab phlu ntawm lub tank tag nrho.
(7) Epoxy curing kub tsis kam yog feem ntau 80 ~ 100 ℃.Epoxy resin kub resistant ntau yam tuaj yeem ncav cuag 200 ℃ lossis siab dua.
