FR5 Hard Epoxy Glassfiber Laminated Sheet
Mafotokozedwe Akatundu
Chogulitsachi chinapangidwa ndi kutentha kwambiri komanso kuthamanga kwambiri pogwiritsa ntchito nsalu yagalasi yopanda alkali yopangidwa ndi ulusi wapadera wa epoxy, ndi chinthu choteteza kutentha cha grade F. Chili ndi mphamvu zambiri zamakina pansi pa kutentha kwapakati, komanso mphamvu zamagetsi zokhazikika pansi pa kutentha kwakukulu. Chimagwiritsidwa ntchito mumakina, zamagetsi ndi zamagetsi ngati zinthu zoteteza kutentha kwambiri. Chili ndi mphamvu zambiri zamakina, mphamvu yamakina yotenthetsera, kukana moto, kukana kutentha komanso kukana chinyezi.
Kutsatira Miyezo
Mogwirizana ndi GB/T 1303.4-2009, ma laminates olimba a mafakitale a thermosetting resin - Gawo 4: ma laminates olimba a epoxy resin, IEC 60893-3-2-2011, zotetezera - ma laminates olimba a mafakitale a thermosetting resin - Gawo 3-2 la mfundo za EPGC204 payokha.
Mawonekedwe
1. Katundu wapamwamba wamakina pansi pa kutentha kwapakati;
2.Kukhazikika kwa magetsi kwabwino pansi pa kutentha kwakukulu;
3. Mphamvu yapamwamba yamakina
4. Mphamvu yayikulu yamakina pansi pa kutentha kwakukulu;
5. Kukana kutentha kwambiri;
6. Kukana chinyezi kwambiri;
7. Kugwira ntchito bwino kwa makina;
8. Kukana kutentha: Giredi F;
9. Katundu woletsa moto: UL94 V-0
Kugwiritsa ntchito
Amagwiritsidwa ntchito pa zida zamakanika, zamagetsi, zamagetsi ngati zinthu zotetezera kutentha, komanso amagwiritsidwa ntchito mu mafuta a transformer ndi malo onyowa.
FR5 poyerekeza ndi FR4, TG ndi yokwera, kukhazikika kwa kutentha ndi giredi F (madigiri 155), FR5 yathu yapambana mayeso a EN45545-2:2013+A1:2015: Ntchito za sitima - Chitetezo cha moto pa magalimoto a sitima - Gawo 2: Zofunikira pakuwongolera moto pa zipangizo ndi zigawo zake. ndipo zivomerezedwe ndiCRRC,tikuyamba kupereka FR5 kwaCRRCkuyambira 2020. Ngati muli ndi mafunso chonde titumizireni uthenga.
