Txhawm rau kom ntseeg tau qhov zoo ntawm qhov loj-caliber epoxy iav fiber ntau yeeb nkab, dab tsi yog qhov yuav tsum tau ua rau cov khoom siv ntau lawm

Loj-inch epoxy iav fiber ntau raj yog ua los ntawm hluav taws xob alkali-dawb iav fiber ntau daim ntaub impregnated nrog epoxy resin, thiab ua tiav los ntawm ci thiab 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. .

Dielectric zog thiab zoo machinability. Cov qib cua sov tuaj yeem muab faib ua qib B (130 degrees) F qib (155 degrees) H qib (180 degrees) thiab qib C (siab dua 180 degrees). Nws yog qhov tsim nyog rau insulating cov khoom siv hauv cov khoom siv hluav taws xob, thiab tuaj yeem siv rau hauv qhov chaw ntub dej thiab cov roj hloov pauv.

Qhov saum npoo yuav tsum tiaj tus thiab du, tsis muaj npuas, roj thiab impurities. Xim tsis sib xws, khawb, me ntsis qhov siab tsis sib xws uas tsis cuam tshuam rau kev siv tau tso cai. Laminated iav ntaub rods nrog ib txoj kab uas hla ntawm ntau tshaj 25 hli tau tso cai kom muaj cov kab nrib pleb ntawm qhov kawg lossis ntu uas tsis cuam tshuam rau kev siv.

Loj-caliber epoxy iav fiber ntau raj yog tsim los ntawm epoxy resin, curing agent, accelerator thiab additives. Lub Cheebtsam ntawm epoxy resin kua nplaum yuav tsum xav txog tsis tsuas yog cov kev cai ntawm cov khoom kho (vim hais tias lub tshav kub tsis kam, tshuaj tsis kam, thiab electromechanical zog ntawm cov winding khoom nyob ntawm seb cov muaj pes tsawg leeg ntawm epoxy resin kua nplaum), tab sis kuj cov kev xav tau kev pab. cov txheej txheem winding molding, Txwv tsis pub nws tsis tuaj yeem raug mob rau hauv cov duab. Vim li no, cov kev cai yooj yim rau epoxy resin kua nplaum yog raws li hauv qab no.

① Lub fluidity ntawm resin kua nplaum yuav tsum zoo kom ntseeg tau tias cov fibers yog saturated, cov kua nplaum cov ntsiab lus yog uniform, thiab cov npuas nyob rau hauv daim ntawv xov paj tuaj yeem tawm. Yog li, nws cov viscosity yuav tsum tau tswj tsis pub dhau 0.35 ~ 1Pa·s. Yog tias qhov viscosity me me, qhov nkag mus tau zoo, tab sis nws yooj yim los poob cov kua nplaum cov ntsiab lus thiab cuam tshuam rau kev ua haujlwm ntawm electromechanical ntawm cov khoom. Txawm li cas los xij, yog tias cov viscosity loj dhau, nws nyuaj rau nkag mus rau hauv qhov sib txawv fiber ntau, ua rau muaj ntau cov npuas hauv cov khoom, uas tseem cuam tshuam rau qhov zoo ntawm cov khoom. Tsis tas li ntawd, lub siab viscosity ua rau muaj kev kub ntxhov, uas yuav ua rau muaj kev tsis yooj yim rau cov txheej txheem winding.

② Lub sijhawm siv yuav tsum ntev. Txhawm rau kom muaj kev sib tw zoo, lub sijhawm gel ntawm cov kua nplaum yuav tsum ntau dua 4h

③ Lub elongation ntawm cov kho resin kua nplaum sib tw nrog cov khoom siv ntxiv, uas tuaj yeem tiv thaiv kev ntxhov siab sab hauv thaum kho.

④ Cov kua nplaum nplaum yog cov kuab tshuaj tsis muaj kuab lom, yog li ntawd muaj qee qhov volatiles thiab tsis txhob muaj cov kuab tshuaj volatilization thaum lub sijhawm kho kom cuam tshuam rau tag nrho cov khoom compactness. Qhov no tseem ceeb dua rau winding molded rwb thaiv tsev qhov chaw siv hauv cov khoom siv hluav taws xob.

Lub raj tub ntxhais siv rau qhov loj-inch epoxy iav fiber ntau raj dov laminated raj yog ib qho tseem ceeb rau kev tsim cov raj laminated. Nws qhov tseeb qhov tseeb ncaj qha cuam tshuam qhov tseeb ntawm sab hauv txoj kab uas hla ntawm lub laminated raj, thiab nws qhov roughness ncaj qha cuam tshuam qhov roughness ntawm sab hauv phab ntsa ntawm lub laminated raj. Yog li ntawd, nws yog ib qho tsim nyog los tiv thaiv qhov chaw ntawm lub raj tub ntxhais los ntawm cov pob, xeb thiab deformation thaum lub sij hawm tsim khoom, kev thauj mus los thiab khaws cia.
