alumina woyendetsa kutentha

Chodzaza kutentha monga momwe dzina lake likusonyezera chimawonjezedwa mu matrix, chomwe chimagwiritsidwa ntchito kuwonjezera kutentha kwa chodzaza, alumina, magnesium oxide, zinc oxide, aluminium nitride, boron nitride, silicon carbide, ndi zina zotero. Pakati pawo, makamaka micron alumina, ufa wa silicon ngati thupi lalikulu. Kapangidwe ka alumina kamakhudza kwambiri kutentha kwa alumina. Ufa wa alumina wozungulira ndi ufa wa micron, wokhala ndi kutentha kwakukulu, kutchinjiriza kwambiri, kuuma kwambiri, kukana kutentha kwambiri, kukana kukwawa, kukana dzimbiri, ndi zina zotero; Kuyera kwambiri, mawonekedwe abwino, kukhazikika bwino, kugawa tinthu tating'onoting'ono tochepa, ndi kudzaza pang'ono kuti pakhale kutentha kwakukulu. Chiyambi cha alumina woyendetsa kutentha: alumina woyendetsa kutentha ndi kristalo woyera wopangidwa pansi pa kutentha kwakukulu. Pali ufa wambiri wa alumina, koma alumina yomwe imagwiritsidwa ntchito popereka kutentha ikuphatikizapo alumina wozungulira (zf-kq series), alumina wozungulira (zf-kk series), alumina wophatikizana (zf-kqm, KCM series), ndi zina zotero. Alumina woyendetsa kutentha ayenera kukhala ndi mawonekedwe a kugawa kwa tinthu tating'onoting'ono, kukhazikika kwa tinthu tating'onoting'ono bwino, K yokwera kutentha komanso kuchuluka kwa magawo odzaza pambuyo posintha ma coupling. Kawirikawiri, kukula kwa tinthu tating'onoting'ono ta alumina woyendetsa kutentha kumatha kulamulidwa pa 5um, ndipo kutentha kumatha kufika pakati pa 3-10w /mk malinga ndi kuchuluka kosiyanasiyana kwa kudzaza.
