Epoxy Glass Cloth Rigid Laminated Sheets (mapepala a EPGC)
EPGC mndandanda wa Epoxy Glass Nsalu Yolimba Yoyimitsidwa Mapepala imakhala ndi nsalu yagalasi yolukidwa yokhala ndi epoxy thermoseting resin, yopangidwa ndi kutentha kwambiri komanso kuthamanga kwambiri.Nsalu yagalasi yolukidwa iyenera kukhala yopanda alkali ndipo imathandizidwa ndi silane coupler.Mapepala amtundu wa EPGC akuphatikiza EPGC201 (NMEMA G10), EPGC202(NEMA FR4), EPGC203(NEMA G11), EPGC204 (NEMA FR5), EPGC306 ndi EPGC308.
Mapepala a EPGC (kalasi yotentha: B～H), opangidwa malinga ndi IEC60893-3-2.Mapepalawa ali ndi mphamvu zamakina kwambiri (kutentha kwa mphamvu yosungira mphamvu kungathe kufika pa 50%) pansi pa kutentha kwapakati kapena kutentha kwapakati, komanso mphamvu yamagetsi yokhazikika (kukana kwa kutchinjiriza pambuyo pa kumizidwa kumafika 1012Ω) mu chikhalidwe cha chinyezi.Komanso ndi kupirira kwamagetsi apamwamba / kupirira voteji (kupitirira 35kV), kufanana ndi lamination.EPGC202, EPGC204 ndi EPGC306 alinso ndi katundu wabwino kwambiri woletsa moto.Mapepalawa adadutsanso kuzindikira zinthu zapoizoni komanso zoopsa (ndi RoHS Report).
Amagwiritsidwa ntchito ngati magawo opangira zida zamagetsi mu Gulu la BH ma mota zamagetsi, zida zamagetsi, zomwe zili ndi zofunikira zokana moto kapena ayi, kapena ntchito zina.
makulidwe omwe alipo:0.30mm ~ 200mm
Kukula kwa pepala komwe kulipo:
1500mm * 3000mm, 1220mm * 3000mm, 1020mm * 3000mm, 1020mm * 2440mm, 1220mm * 2440mm, 1500mm * 2440mm, 1000mm * 2000mm, 1200mm * 2000mm kukula kwake.

Packing Ndi Kusunga
Zolembazo ziyenera kusungidwa pamalo pomwe kutentha sikudutsa 40 ℃, ndikuyikidwa mopingasa pa bedplate yokhala ndi kutalika kwa 50mm kapena kupitilira apo.Khalani kutali ndi moto, kutentha (zida zotenthetsera) ndi dzuwa.Nthawi yosungiramo mapepala ndi miyezi 18 kuyambira tsiku lochoka kufakitale.Ngati nthawi yosungirayi yadutsa miyezi 18, mankhwalawa atha kugwiritsidwanso ntchito atayesedwa kuti akhale oyenerera.
Ndemanga ndi Zodzitetezera Pakugwiritsa Ntchito
1 Machining ayenera kutsatira JB/Z141-1979,Machining njira kutchinjiriza laminated mankhwala, chifukwa mapepalawa ali ndi kusiyana pakati pa chikhalidwe ndi chitsulo.
2 Kuthamanga kwakukulu ndi kuya kwazing'ono kumagwiritsidwa ntchito popanga makina chifukwa cha kufooka kwa matenthedwe a mapepala.
3 Kukonza ndi kudula mankhwalawa kumatulutsa fumbi ndi utsi wambiri.Njira zoyenera ziyenera kuchitidwa kuti zitsimikizire kuti fumbi lili m'malire ovomerezeka panthawi yogwira ntchito.Amalangizidwa kuti apumule mpweya wabwino ndi kugwiritsa ntchito fumbi/masks oyenera.
4 Mapepalawa amakhala ndi chinyezi atapangidwa ndi makina, tikulimbikitsidwa kuti tivale zotchingira zoziziritsa kukhosi.
