Epoxy utomoni kutchinjiriza board zizindikiro luso

Nthawi zambiri, kalasi ya insulating board si luso kalasi, koma mkulu kutentha kukana kalasi ya insulating zakuthupi. The insulating katundu wa insulating zipangizo zimagwirizana kwambiri ndi kutentha. Kutentha kwapamwamba, kumakhala koipitsitsa kwambiri kutsekemera kwa zinthu zotetezera. Pofuna kuonetsetsa mphamvu ya dielectric, chilichonse chotchingira chimakhala ndi kutentha koyenera kovomerezeka. Pansi pa kutentha uku, itha kugwiritsidwa ntchito motetezeka kwa nthawi yayitali. Ngati ipitilira kutentha uku, imakalamba mwachangu. Malinga ndi kuchuluka kwa kukana kutentha, zida zotetezera zimagawidwa kukhala Y, A, E, B, F, H, C ndi magiredi ena. Mwachitsanzo, kutentha kwakukulu kovomerezeka kwa Class A zotetezera ndi 105 ° C, ndipo zipangizo zambiri zotetezera zomwe zimagwiritsidwa ntchito kawirikawiri ndi ma transformers ndi ma motors ndi a Gulu A, monga epoxy resin insulating board ndi zina zotero.

Kutenthetsa kutentha kalasi A kalasi E kalasi B kalasi F kalasi H kalasi

Kutentha kwakukulu kovomerezeka (℃) 105 120 130 155 180

Mapiritsi a kutentha kwa mphepo (K) 60 75 80 100 125

Kutentha kwantchito (℃) 80 95 100 120 145

Kenako, ndikutengerani kuti muphunzire zina zokhudzana ndi bolodi la epoxy resin:

The epoxy resin board amapangidwa ndi galasi fiber nsalu yomangidwa ndi epoxy resin ndikutenthedwa ndi kukanikizidwa. Chitsanzo ndi 3240. Lili ndi zida zapamwamba zamakina pa kutentha kwapakati komanso mphamvu zamagetsi zokhazikika pa kutentha kwakukulu. Ndiwoyenera kupangira zida zamakina apamwamba kwambiri pamakina, zida zamagetsi ndi zamagetsi, zokhala ndi zida zambiri zamakina ndi dielectric, kukana kutentha kwabwino komanso kukana chinyezi. Gulu lolimbana ndi kutentha F (madigiri 155).

Muzopangira za bolodi la epoxy resin, epoxy resin nthawi zambiri amatanthauza mankhwala a polima okhala ndi magulu awiri kapena kuposerapo mu molekyulu. Kupatulapo ochepa, ma molekyulu awo achibale awo si okwera. Mapangidwe a maselo a epoxy resin amadziwika ndi kukhalapo kwa magulu ogwira ntchito a epoxy mu unyolo wa maselo, ndipo magulu a epoxy akhoza kukhala kumapeto, pakati kapena cyclic dongosolo la unyolo wa maselo. Chifukwa cha magulu a epoxy omwe amagwira ntchito pamapangidwe a maselo, amatha kulumikizidwa ndi mitundu yosiyanasiyana ya machiritso kuti apange ma polima osasungunuka komanso osasunthika okhala ndi njira zitatu zolumikizira maukonde.

1. Mfundo makulidwe: 0.5 ~ 100mm

2. Nthawi zonse mfundo: 1000mm * 2000mm

3. Mtundu: wachikasu

4. Malo Ochokera: Pakhomo

5. Imatenthedwa ndi kupunduka pa kutentha kwakukulu kwa 180 ° C. Nthawi zambiri, sichitenthedwa pamodzi ndi zitsulo zina, zomwe zingayambitse kusinthika kwa pepala lachitsulo.
