Chigawo cha Alumina Ceramic cha Lighting System
Munda Wofunsira
Zigawo za aluminiyamu zadothi zimagwiritsidwa ntchito kwambiri powunikira ndi katundu wamakina apamwamba, kuuma kwakukulu, kuvala kwautali, kukana kwakukulu kwa kutchinjiriza, zodzitetezera bwino za dzimbiri, kupirira kutentha kwambiri.
Zida za aluminiyamu za ceramic zitha kugwiritsidwa ntchito mu nyali ndi nyali.The matenthedwe madutsidwe a aluminiyamu ceramic magawo ranges kuchokera 29. 3W / (m · K) kuti 35W / (m · K), amene ali pafupifupi khumi kwa makumi awiri kuwirikiza kawiri a aluminiyamu magawo.Akagwiritsidwa ntchito pa ma LED, amatha kutentha bwino ndikuwonjezera moyo wa LED.Ngati okonzeka ndi wabwino kutentha dissipation rediyeta, sipadzakhala mphambano kutentha konse, amene angapereke chitetezo pazipita kwa mikanda nyali.China ndi msika waukulu wa zigawo alumina ceramics.zambiri za alumina ceramic zimatumizidwa kunja.
Tsatanetsatane
Chofunikira pa kuchuluka:1pc mpaka 1 miliyoni pcs.Palibe MQQ yochepa.
Sample nthawi yotsogolera:kupanga zida ndi 15days+ kupanga 15days.
Nthawi yopanga:Masiku 15 mpaka 45.
Nthawi yolipira:kukambilana ndi mbali zonse.
Njira yopangira:
Alumina(AL2O3) ceramic ndi ceramic ya mafakitale yomwe imakhala ndi kuuma kwambiri, kuvala kwautali, ndipo imatha kupangidwa ndi kugaya diamondi.Amapangidwa kuchokera ku bauxite ndipo amamalizidwa ndi jekeseni, kukanikiza, sintering, kugaya, sintering ndi machining process.

Kulongedza
Nthawi zambiri timagwiritsa ntchito zinthu zomwe sizingawonongeke, zomwe sizingawonongeke.Timagwiritsa ntchito chikwama cha PP ndi mapaleti amatabwa katoni malinga ndi zomwe kasitomala amafuna.Zoyenera kuyenda panyanja ndi ndege.
