Silika nitride keramika
Nā hiʻohiʻona
● Hoʻohālikelike ʻia me ka alumini silicate ceramic fiber, Silicon nitride ceramic i ʻoi aku ka ikaika a ʻoi aku ka maikaʻi o ka waiwai ʻole. Ke hoʻohana ʻia no nā plugs, sprue tubes a me nā piʻi wela wela i ka ʻoihana foundry, ʻoi aku ka kiʻekiʻe o ka hilinaʻi a me ka lōʻihi o ke ola lawelawe.
● ʻO nā ʻano paipu riser a pau i hoʻohana ʻia i ka hoʻolei ʻana i ka ʻumekaumaha, ka hoʻolei ʻokoʻa ʻokoʻa a me ka hoʻolei haʻahaʻa haʻahaʻa he koi kiʻekiʻe ma ka insulation, ke kūpaʻa haʻalulu wela a me ka waiwai ʻole. ʻO ka silikon nitride ceramic ka koho maikaʻi loa i ka nui o nā hihia.
● ʻO ka ikaika flexural o Silicon nitride ceramic he 40-60MPa wale nō, eʻoluʻolu e hoʻomanawanui a me ka noʻonoʻo i ka wā e hoʻokomo ai e pale i ka pōʻino o waho.
● I loko o nā noi kahi e pono ai ka paʻa paʻa, hiki ke hoʻomaʻamaʻa pono ʻia nā ʻano like ʻole me ka sandpaper a i ʻole nā huila abrasive.
● Ma mua o ka hoʻokomoʻana, pono e mālama i ka huahana mai ka makū a maloʻo ma mua.
Nā pōmaikaʻi nui:
- Ka ikaika kiʻekiʻe a me ka paʻakikī: ʻO ka Silicon nitride ka hui pū ʻana o ka ikaika kiʻekiʻe a me ka paʻakikī, e hāʻawi ana i ka lole maikaʻi a me ke kūpaʻa hopena ʻoiai ma lalo o nā kūlana koʻikoʻi.
- Kūleʻa Haʻalulu Thermal maikaʻi loa: Hiki i ka silikon nitride ceramics ke kū i ka hoʻololi wikiwiki o ka wela me ka ʻole o ka haki ʻana a i ʻole ka nalowale ʻana i ka pono, e kūpono ia no nā kaiapuni wela kiʻekiʻe, e like me nā umu ahi a i ʻole nā mīkini.
- Kūleʻa Wela Nui: Me kahi helu heheʻe kiʻekiʻe a me ka hiki ke mālama i ka ikaika ma nā mahana kiʻekiʻe, kūpono ka silicon nitride no nā noi e koi ana i ka paʻa lōʻihi ma lalo o ka wela nui.
- Hoʻonui Thermal Haʻahaʻa: He haʻahaʻa haʻahaʻa haʻahaʻa ka hoʻonui ʻana o kēia mea ceramic, e hōʻoiaʻiʻo ana i ka paʻa ʻana o ka dimensional i ka wā o ka piʻi ʻana o ka mahana, e hōʻemi ana i ka hopena o ka deformation thermal.
- Kū'ē Kū'ē Kū'ē: Paʻa loa ka silikoni nitride i ka ʻino kemika, me nā ʻakika, alkalis, a me nā metala hoʻoheheʻe ʻia, no laila kūpono ia no nā kaiapuni kemika paʻakikī.
- Māmā: ʻOiai kona ikaika, ʻoi aku ka maʻalahi o ka silicon nitride i ka hoʻohālikelike ʻia me nā metala, ʻoi aku ka maikaʻi ma nā ʻoihana e like me ka aerospace a me ka automotive, kahi mea koʻikoʻi ka hoʻēmi kaumaha.
- Hoʻokohu Uila: Loaʻa i ka silikon nitride seramika nā waiwai hoʻokaʻawale uila maikaʻi loa, e kūpono ana iā lākou no nā noi uila a me nā noi uila e koi ana i nā mea me ke kūpaʻa wela a me ka uila.
- Biocompatibility: He mea biocompatible kēia ceramic, e ʻae iā ia e hoʻohana ʻia i nā lāʻau lapaʻau, ʻoi loa i nā noi orthopedic e like me nā implants.
