Yuav ua li cas ua cov epoxy cob rau hauv epoxy iav fiber ntau raj

Cov txheej txheem ntau lawm ntawm epoxy iav fiber ntau raj yog qhov nyuaj. Yuav ua li cas ua epoxy resin rau hauv epoxy iav fiber ntau raj? Cov nram qab no epoxy iav fiber ntau raj manufacturers yuav qhia koj:

Cov khoom siv raw rau kev ua epoxy iav fiber ntau raj yog ib qho monotonous adhesive-txuas substrate ua cov khoom siv thiab cov khoom siv nplaum uas siv tib lub sijhawm.

Feem ntau cov ntaub iav thiab daim ntawv impregnated nrog phenolic resin los yog phenolic epoxy resin, paj rwb ntaub impregnated nrog tib resin tsuas yog siv nyob rau hauv ib rooj plaub.

Thaum lub sij hawm winding, cov khoom siv nplaum dhau los ntawm qhov nro cov menyuam thiab cov ntawv qhia cov menyuam thiab nkag mus rau hauv cov menyuam uas muaj cua sov rau pem hauv ntej. Tom qab ua kom sov thiab ua nplaum, nws yog qhov txhab ntawm lub raj tub ntxhais qhwv nrog zaj duab xis. Lub nro roller siv qee qhov nro rau cov ntaub nplaum nplaum. Ntawm ib sab, lub winding yog nruj, thiab ntawm qhov tod tes, lub raj tub ntxhais tuaj yeem dov nrog kev pab ntawm kev sib txhuam. Qhov kub ntawm cov menyuam txhawb nqa pem hauv ntej yuav tsum tau tswj nruj heev. Thaum qhov kub thiab txias siab dhau lawm, cov resin yuav ntws tau yooj yim, thiab thaum qhov kub thiab txias tsis dhau, qhov adhesion zoo heev tsis tuaj yeem lav.

Thaum siv txoj kev winding los tsim cov yeeb nkab, ua ntej siv tus neeg sawv cev tso rau ntawm cov yeeb nkab core. Tus neeg sawv cev tso tawm tuaj yeem ua los ntawm cov roj av jelly, asphalt thiab dawb ciab ntawm qhov sib piv ntawm 1.5: 1: 1 tom qab sib xyaw thiab txias. Thaum siv, siv turpentine los dilute nws mus rau hauv ib qho muab tshuaj txhuam. Lub raj tub ntxhais coated nrog tus neeg sawv cev tso tawm yuav tsum tau them nrog ib feem ntawm cov khoom nplaum raws li daim ntawv rov qab, thiab tom qab ntawd muab tso rau nruab nrab ntawm ob qho kev txhawb nqa thiab lub siab rau cov menyuam raug muab tso rau hauv lub raj tub ntxhais.

Ncaj cov ntaub nplaum rau ntawm lub tshuab winding kom nws sib tshooj nrog ib qho kawg ntawm zaj duab xis, thiab tom qab ntawd cua nws maj mam, thiab qhov nrawm tuaj yeem nce ntxiv tom qab ib txwm muaj.

Nws tuaj yeem tswj tau ntawm 80-120 ℃ thaum winding phenolic raj. Thaum nws raug mob mus rau lub thickness tsis tu ncua, daim kab xev yog thaiv, thiab cov dov raj dawb paug thiab lub raj tub ntxhais raug tshem tawm ntawm lub raj coiling tshuab thiab xa mus rau qhov cub rau kho. Thaum tsim cov phenolic coiled raj, yog tias phab ntsa thickness tsawg dua 6 hli, nws tuaj yeem muab tso rau hauv qhov cub ntawm 80-100 ℃, thiab tom qab ntawd rhaub rau 170 ℃ los kho nws rau 2h. Tom qab lub solidification tiav, tshem tawm ntawm qhov cub, txias nws ib txwm nyob rau hauv chav tsev kub, thiab thaum kawg tshem tawm cov yeeb nkab los ntawm cov yeeb nkab core.
