spherical alumina ufa
Mafotokozedwe Akatundu
Alumina yozungulira ndi chinthu chochita bwino kwambiri chokhala ndi chiyero chachikulu, tinthu tating'onoting'ono tozungulira, kuuma kwakukulu, kukana kuvala kwambiri, kukana kwa dzimbiri, kukhazikika kwamafuta ambiri komanso kutsekemera kwamagetsi kwabwino.Aluminiyamu yozungulira imakhala ndi kuuma kwambiri komanso mphamvu, zomwe zimapangitsa kuti ikhale chinthu choyenera kuvala.M'madera a ceramics, zamagetsi, makampani opanga mankhwala ndi zomangamanga, alumina yozungulira imagwiritsidwa ntchito kwambiri popanga zipangizo zamakono zadothi, zitsulo zosagwira ntchito zapamwamba, zida za injini zamagalimoto, ndi zina zotero. sungani machitidwe okhazikika m'malo ovuta.Mwachitsanzo, m'malo a Marine, makampani opanga mankhwala, mafakitale amagetsi ndi madera ena, aluminiyamu yozungulira imagwiritsidwa ntchito popanga zombo, zida zamagetsi, zida zamagetsi ndi zina zotero.Aluminiyamu yozungulira imakhala ndi kukhazikika kwamafuta komanso kutsekemera kwamagetsi, kotero kuti imatha kugwira ntchito bwino pakutentha kwambiri komanso malo othamanga kwambiri.Pazinthu zamagetsi, aluminiyamu yozungulira imagwiritsidwa ntchito popanga zida zamagetsi zotentha kwambiri, zida zamagetsi zamagetsi, ndi zina zambiri.

Zamalonda
Kudzaza Kwakukulu: Mlingo wapamwamba wa spheroidization, kugawa kwa tinthu tating'onoting'ono, kukwaniritsa kachulukidwe kake ka silicone ndi utomoni wa epoxy, kuti mutenge kusakaniza ndi kukhuthala kochepa komanso kuyenda kwapamwamba;
High Thermal Conductivity: Chifukwa cha mawonekedwe ake abwino kwambiri a mpira, chodzaza chomwe chimagwiritsidwa ntchito muzopangira chimatha kutengera kutentha kosiyanasiyana.Dongosolo lonse losakanikirana liri mu kubalalitsidwa kwabwino, kotero zomaliza zimakhala ndi matenthedwe abwino kwambiri komanso katundu wakuthupi;
Low Abrasion: Poyerekeza ndi ufa wosakhazikika, kugwiritsa ntchito spherical filler kumatha kuchepetsa kuyabwa kwa chosakanizira, makina omangira ndi zida zina, ndikutalikitsa moyo wogwira ntchito wa zida zoyenera.
