ʻO ka Dia3mm SiC pōpō seramika Silicon carbide Ceramic Polycrystaline
He paʻakikī kiʻekiʻe loa nā keramika SiC, ʻo ka lua wale nō i ka daimana, e hoʻolilo ana iā ia i mea maikaʻi loa i ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa ʻana i ke kahakaha a me nā ʻano ʻē aʻe. I ka manawa like, he ikaika kūlou kiʻekiʻe hoʻi a me ka ikaika compressive, a hiki ke mālama i ka hana paʻa i nā wahi ʻino e like me ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe. ʻO ke kiko heheʻe o nā keramika silicon carbide he kiʻekiʻe a hiki i ka 2700 ℃, hiki ke holo no ka manawa lōʻihi i kahi mahana kiʻekiʻe a ʻaʻole maʻalahi ka deformation a me ka degradation. Eia kekahi, he kūpaʻa maikaʻi nā keramika silicon carbide i ka corrosion i ka hapa nui o nā waikawa, nā kumu, nā paʻakai a me nā kemika ʻē aʻe, a kūpono no nā ʻano kaiapuni kemika like ʻole. ʻO ka hope loa, he haʻahaʻa hoʻi ka coefficient o ka hoʻonui wela, hiki ke mālama i ka paʻa dimensional i ke kaiapuni o nā loli o ka mahana.
Nā noi o nā keramika SiC
Hoʻohana nui ʻia nā keramika silikona carbide i ka hana ʻana i nā mea refractory, e like me nā uhi umu, nā uhi umu, a me nā ipu wela kiʻekiʻe, ma muli o kona kūpaʻa wela kiʻekiʻe a me ka palaho. I kēia manawa, hoʻohana nui ʻia kona paʻakikī kaulike o ka abrasive a me ka palaoa like i ka ʻoki ʻana, ka wili ʻana, ka polishing a me nā kaʻina hana ʻē aʻe. Loaʻa i nā pads brake keramika silikona carbide ke koina kiʻekiʻe o ke kūpaʻa friction a me ka abrasion, hiki ke hoʻohana ʻia i loko o ka ʻōnaehana brake o nā kaʻa, nā kaʻaahi a me nā kaʻa halihali ʻē aʻe. Eia kekahi, hiki ke hoʻopili ʻia i nā papa anti-wear, nā mea hoʻoili scraper, nā elevators bākeke a me nā lako ʻē aʻe e hōʻemi pono i ka ʻaʻahu o nā lako. Loaʻa i ka mea hoʻololi wela silikona carbide ka hana hoʻololi wela maikaʻi loa a hoʻohana nui ʻia i ka mana uila, ka petroleum, kemika a me nā ʻoihana ʻē aʻe. ʻO ka hope loa, hiki i nā ʻāpana mīkini silicon carbide keramika ke mālama i ka hana paʻa i nā wahi wela kiʻekiʻe a me ke kaomi kiʻekiʻe, e hoʻomaikaʻi ana i ka mana mīkini a me ka pono.
