ʻO nā ʻokoʻa ma waena o nā keramika silicon carbide a me nā keramika silicon nitride

Ma ke kahua o nā mea holomua,nā keramika silicon carbide (SiC) a me ka silicon nitride (Si3N4)ua lilo i ʻelua o nā hui koʻikoʻi loa, kēlā me kēia me nā waiwai kū hoʻokahi a me nā noi. He mea koʻikoʻi ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o kēia mau keramika ʻelua no nā ʻoihana e hilinaʻi nei i nā mea hana kiʻekiʻe. ʻO Shandong Zhongpeng Special Ceramics Co., Ltd. kahi ʻoihana ʻenehana kiʻekiʻe e loea ana i ka hana ʻana i nā keramika silicon carbide, e pāʻani ana i kahi kuleana koʻikoʻi ma kēia kahua, e hāʻawi ana i nā ʻike hohonu i nā waiwai a me nā noi o kēia mau mea.

Ua ʻike ʻia nā keramika silikona carbide no ko lākou paʻakikī kūikawā a me ke kūpaʻa wela. Loaʻa iā lākou ka silicon a me ke kalapona, e hui pū ana e hana i kahi hui i loaʻa ka pale maikaʻi loa i ka ʻaʻahu a me ka pala. ʻO kēia ka mea e kūpono ai nā keramika silikona carbide no nā noi ma nā ʻano ʻino e like me ka aerospace, automotive a me semiconductor. ʻO ka conductivity wela kiʻekiʻe o Silicon carbide e hiki ai iā ia ke hoʻokuʻu i ka wela me ka maikaʻi, e kūpono ai no nā noi wela kiʻekiʻe. Hoʻohana ʻo Shandong Zhongpeng Special Ceramics Co., Ltd. i kēia mau waiwai e hana i nā keramika silikona carbide kiʻekiʻe e hoʻokō i nā pono koi o nā ʻoihana like ʻole.

ʻO nā keramika Silicon nitride, ma ka ʻaoʻao ʻē aʻe, he mau waiwai mechanical maikaʻi loa, me ka ikaika kiʻekiʻe a me ka paʻakikī. ʻO nā keramika Si3N4, i haku ʻia me ka silicon a me ka nitrogen, he kūpaʻa loa ia i ka haʻalulu wela a he haʻahaʻa ko lākou coefficient o ka hoʻonui wela i hoʻohālikelike ʻia me ka silicon carbide. ʻO kēia ka mea e lilo ai nā keramika silicon nitride i koho maikaʻi loa no nā noi e pono ai nā mea e kū i nā loli wikiwiki o ka mahana, e like me nā turbine kinoea a me nā mea ʻoki. ʻO ka microstructure kū hoʻokahi o Silicon nitride e hāʻawi pū iā ia i ka paʻakikī haki maikaʻi loa, e lilo ia i mea koho no nā ʻoihana e pono ai nā ʻāpana paʻa.

I ka hoʻohālikelike ʻana i nā mea ʻelua, ʻo kekahi o nā ʻokoʻa koʻikoʻi loa i ko lākou mau waiwai wela. Hiki i nā keramika silikona carbide ke kū i nā mahana kiʻekiʻe ma mua o nā keramika silicon nitride, e kūpono ai lākou no ka hoʻohana ʻana i nā noi wela kiʻekiʻe loa. Eia nō naʻe, ʻo ka hiki o ka silicon nitride ke kū i ka haʻalulu wela e hāʻawi iā ia i kahi pono i nā wahi me nā loli wela nui. He mea koʻikoʻi kēia ʻokoʻa no nā ʻenekinia a me nā mea hoʻolālā i ke koho ʻana i kahi mea no kahi noi kikoʻī, no ka mea, hiki i ke koho ʻana o ka mea ke hoʻopilikia nui i ka hana a me ke ola lawelawe.

ʻO kekahi ʻokoʻa nui ma waena o nā keramika silicon carbide a me nā keramika silicon nitride ʻo ko lākou kūpaʻa kemika. He kūpaʻa loa ka Silicon carbide i ka oxidation a hiki ke mālama i kona mau waiwai ʻoiai i nā wahi kemika corrosive. ʻO kēia ka mea kūpono no ka hana kemika a me nā noi hana semiconductor. I ka hoʻohālikelike ʻana, ʻoiai ke kūpaʻa kemika o nā keramika silicon nitride, ʻaʻole paha e hana maikaʻi i kekahi mau wahi corrosive. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau waiwai kemika no nā ʻoihana e hana ana i nā kūlana paʻakikī no ka mea e pili ana i ke koho ʻana i nā mea a me ka hoʻolālā huahana.

ʻOkoʻa loa nā kaʻina hana no nā keramika silicon carbide a me silicon nitride. Hana pinepine ʻia nā keramika Silicon carbide ma o ka sintering, kahi hana e pili ana i ka hoʻomehana ʻana i ka mea i kahi mahana ma lalo o kona wahi heheʻe e hoʻokō ai i ka densification. Hiki i kēia ʻano hana ke hana i nā ʻano paʻakikī a me nā ʻāpana density kiʻekiʻe. I ka hoʻohālikelike ʻana, hana pinepine ʻia nā keramika silicon nitride me ka hoʻohana ʻana i ka hui pū ʻana o ka hana pauka a me nā ʻano hana sintering, me ke kaomi wela a i ʻole ka hoʻopaʻa ʻana i ka hopena. Hiki i kēia mau ʻokoʻa i nā kaʻina hana hana ke hoʻopilikia i nā waiwai hope o ka keramika, me kona microstructure a me nā waiwai mechanical.

Ma ke ʻano o ke kumukūʻai, ʻoi aku ke kumukūʻai o nā keramika silicon carbide ma mua o nā keramika silicon nitride ma muli o nā mea maka a me ka ʻenehana hana. Eia nō naʻe, hiki i ka hana lōʻihi a me ke kūpaʻa o ka silicon carbide ke hoʻāpono i ka hoʻopukapuka mua kiʻekiʻe, ʻoi aku hoʻi i nā noi kahi e hiki ai i ka hāʻule ʻana ke hopena i ka downtime nui a i ʻole nā ​​​​pilikia palekana. Ke nānā nei ʻo Shandong Zhongpeng Special Ceramics Co., Ltd. i ka hāʻawi ʻana i nā hopena kūpono me ka ʻole o ka hoʻohaʻahaʻa ʻana i ka maikaʻi, e hōʻoia ana e loaʻa i nā mea kūʻai aku ka waiwai maikaʻi loa no kā lākou hoʻopukapuka kālā ʻana i nā keramika silicon carbide.

I ka hōʻuluʻulu manaʻo, he mea nui nā ʻokoʻa ma waena o nā keramika silicon carbide a me nā keramika silicon nitride a hiki ke hoʻopilikia nui i kā lākou noi ma nā ʻano ʻoihana like ʻole. ʻOi aku ka maikaʻi o ka Silicon carbide i nā wahi wela kiʻekiʻe a me nā wahi ʻino kemika, ʻoiai ʻo ka silicon nitride e hōʻike ana i ka paʻakikī maikaʻi loa a me ke kūʻē ʻana i ka haʻalulu wela. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no nā ʻenekinia a me nā mea hana i ke koho ʻana i nā mea no nā noi kikoʻī. Ma ke ʻano he mea hana alakaʻi o nā keramika silicon carbide, ua kūpaʻa ʻo Shandong Zhongpeng Special Ceramics Co., Ltd. i ka hoʻolaha ʻana i ke kahua o nā keramika holomua, e hāʻawi ana i nā huahana kiʻekiʻe e hoʻokō ana i nā pono e ulu nei o ka ʻoihana hou. Ma ka hoʻohana ʻana i nā waiwai kū hoʻokahi o ka silicon carbide a me ka silicon nitride, hiki i nā ʻoihana ke hoʻomaikaʻi i kā lākou hoʻolālā a hoʻomaikaʻi i ka hana o kā lākou huahana, e hoʻonui hope ana i ka pono a me ka hilinaʻi o kā lākou hana.
