Mkulu koyera graphite ufa kukodzedwa graphite 80mesh kwa zipangizo moto
Graphite ufa
Malo otentha: 4250 ℃
Mulingo wandiweyani: 1.6 ~ 2.2
Iyenera kugwiritsidwa ntchito: carburizer, smelting
Kapangidwe: kutentha kwambiri kugonjetsedwa, conductive, matenthedwe madutsidwe
Graphite ufa ukhoza kugawidwa m'magulu awiri akuluakulu:
1. Grafiti yachilengedwe
2. Synthetic graphite
Mwa iwo, ma graphite achilengedwe ali ndi mitundu iyi:
1. Phokoso la graphite
2. Spheroidal graphite
3. Ma graphite a Micronized
4. graphite yowonjezera
5. Dothi la graphite
Chojambula cha graphite
ndi chilengedwe cha crystalline graphite, chomwe chili chofanana ndi phosphorous ya nsomba ndipo ndi ya hexagonal crystal system.Ili ndi mawonekedwe osanjikiza.Lili ndi katundu wabwino wa kukana kutentha kwapamwamba, conductivity, conduction kutentha, lubrication, plasticity ndi acid-base resistance.
Flake graphite ndi mafuta achilengedwe okhala ndi mawonekedwe osanjikiza, olemera muzinthu komanso mtengo wotsika mtengo.
Natural graphite
amapangidwa ndi kusintha kwa carbon wolemera organic nkhani pansi pa zochita yaitali kutentha ndi kuthamanga kwambiri chilengedwe chilengedwe, ndipo ndi crystallization chilengedwe.Makhalidwe aukadaulo a graphite zachilengedwe makamaka zimadalira mawonekedwe ake a crystalline.Mchere wokhala ndi mawonekedwe osiyanasiyana a crystalline ali ndi mitundu yosiyanasiyana ya mafakitale ndi ntchito.Pali mitundu yambiri ya ma graphite achilengedwe.Malinga ndi ma crystalline morphology, ma graphite achilengedwe amagawidwa kukhala wandiweyani wa crystalline graphite, flake graphite ndi cryptocrystalline graphite.
Ntchito:
Foundry Releasing Agent / Casting Releasing Agent Mafuta abwino pa kutentha kwakukulu,
zomatira bwino, mosavuta nkhungu kumasulidwa.
Ubwino:
1.Kuchepetsa kugwiritsa ntchito mphamvu
2.Kuchepetsa kugwiritsa ntchito recarburizer
3.Chepetsani kuchuluka kwa zinyalala
4.Reduce mpopi kuti tigwire nthawi
5.Chepetsani ndalama zowonongeka
