Koj puas paub ob peb yam ntxwv ntawm epoxy iav fiber ntau yeeb nkab?

Lub epoxy iav fiber ntau raj yog ua los ntawm cov hluav taws xob alkali-dawb iav fiber ntau daim ntaub impregnated nrog epoxy resin, ci, thiab ua tiav los ntawm kub nias nyob rau hauv ib tug forming pwm. Lub cross section yog ib tug round pas nrig. Cov iav ntaub pas nrig muaj cov cuab yeej ua haujlwm siab. Qhov saum npoo ntawm epoxy iav fiber ntau raj yuav tsum du yam tsis muaj npuas, roj stains thiab impurities. Cov xim tsis sib xws, me ntsis txhuam, thiab lwm yam yog tag nrho nyob rau hauv qhov kev tso cai. Epoxy fiberglass kav yog siv rau qhov chaw ntawm cov txheej txheem rwb thaiv tsev hauv cov khoom siv hluav taws xob, huab cua puag ncig thiab cov roj transformer.

Cov yam ntxwv ntawm cov kav dej epoxy iav fiber ntau yog qhov dav, thiab cov peev txheej ntawm daim ntawv thov yog qhov dav, thiab cov ntaub ntawv muaj ntau haiv neeg. Cov resin, curing agent, thiab modifier system yuav luag hloov mus rau qhov yuav tsum tau ntawm ntau daim ntawv thov nyob rau hauv daim ntawv, thiab qhov ntau yuav yog los ntawm tsis tshua muaj viscosity mus rau siab melting point solids. Thib ob, kev kho yog yooj yim heev. Xaiv ntau yam khoom sib txawv, thiab epoxy resin system tuaj yeem kho tau ntawm qhov kub ntawm 0-180 ° C.

Ib yam uas kuv yuav tsum tau hais yog tias nws muaj zog adhesion. Muaj cov polar hydroxyl pawg thiab ether bonds nyob rau hauv cov saw molecular ntawm epoxy resin, uas ua rau nws muaj siab adhesion rau ntau yam khoom. Lub shrinkage ntawm epoxy resin yog tsawg thaum kho, thiab cov kev ntxhov siab sab hauv tsim yog me me, uas kuj pab txhim kho lub zog adhesion. Nws kuj muaj tsawg shrinkage. Cov tshuaj tiv thaiv ntawm epoxy resin thiab curing tus neeg sawv cev yog ua los ntawm cov tshuaj tiv thaiv ncaj qha los yog lub nplhaib-qhib polymerization cov tshuaj tiv thaiv ntawm epoxy pawg hauv cov molecule resin, thiab tsis muaj dej los yog lwm yam khoom lag luam tawm. Raws li cov ntaub ntawv tseem ceeb, piv nrog unsaturated polyester resin thiab phenolic resin, lub shrinkage thaum lub sij hawm kho yog tsawg heev, txog 2%. .
