Shaxda qeexitaanka usha dahaadhka muraayadda Epoxy

Ulaha cidhifka galaas Epoxy waxaa sidoo kale loo yaqaan ulaha bakelite, tiirar bakelite, ulo jiid, iwm. Alaabooyinka waxaa laga sameeyey fiber aramid-xoog-sare iyo fiber galaas uur leh matrix epoxy resin by pultrusion heerkulka sare. Waxay leedahay sifooyinka xoogga aadka u sarreeya, caabbinta xidhashada aad u fiican, caabbinta acid iyo alkali, iyo iska caabin heerkul sare oo heer sare ah. Alaabtu waxay ku habboon tahay qalabka korantada ee sarreeya sida transformers, capacitors, reactors, switches-voltage, iwm. .

Horudhac usha cidhifka galaas epoxy

Usha cidhifka galaas epoxy waxay qabataa fiber aramid-xoog-sare iyo fiber galaas si ay u impregnate matrix resin epoxy ah, oo si joogto ah loo dubay on caaryada xirfadeed by habka “samaynta sawir”, iyo cadaadisay galay alaabta la qaab cross-qaybaha. Sida ulo wareeg ah, ulo labajibbaaran, jeexan jeexjeexan, I-beams, qaybo jeexan, iwm iyo alaabooyin qaabaysan oo kala duwan. Waxay leedahay xoog farsamo oo aad u sarreeya iyo sifooyinka dielectric wanaagsan ee jihada fiber, iyo sidoo kale sifooyinka dherer kasta.

Astaamaha wax soo saarka ee ul cidhifka galaaska epoxy:

1. Sababo la xiriira pultrusion joogto ah ee fiber aramid iyo fiber galaas, alaabtu waxay leedahay iska caabin heer sare ah cadaadiska farsamada iyo xiisadda makaanikada, iyo xooggeeda xajintu waxay gaartaa 1500MPa, taas oo aad uga badan xoogga xajinta ee No. 45 saxnaanta birta, taas oo ah 570Mpa . . Waxqabad koronto oo heer sare ah, u adkeysanaya qiimeynta korantada ee kala duwanaanshaha korantada 10kV-1000kV. Iska caabbinta daxalka adag, xoogga foorarsiga sare, ma fududa in la leexiyo, fududahay in la isticmaalo iyo wixii la mid ah.

2. Heerkulka shaqada muddada-dheer ee la oggol yahay ee badeecaddu waa 170-210 ℃; Heerkulka shaqo ee ugu sarreeya ee wareegga gaaban ee badeecaddu waa 260 ℃ (wakhtigu waa ka yar yahay 5 ilbiriqsi).

3. Dusha sare ee alaabadu waa mid aad u siman, ma jiro midab kala duwan, ma jiro bur, ma xoqin.

4. Darajada caabbinta kulaylka iyo darajada dahaarka ee sheygu waxay gaaraan darajada H.
