ʻO Zirconia kahi papa koʻikoʻi o nā mea seramika e like me nā seramika kiʻekiʻe, a he kumu kumu nui loa ia no ka hoʻomohala ʻana i ka ʻoihana ʻenehana kiʻekiʻe. Zirconia keramika, me ka kiʻekiʻe hehee ai a me ka paila wahi, kiʻekiʻe paakiki, maikaʻi aahu kū'ē, e like me ka insulator i ka lumi wela, a me ke kiʻekiʻe wela loaʻa nā waiwai maikaʻi e like me ka uila conductivity.Zirconia ceramics ua komo i loko o ka laulā huahelu o nā mahinaʻai a noho i ka hapa nui o. ko kakou ola ana. Aia nā wahi lawelawe: kamaʻilio 5G, petrochemical, nā mea lapaʻau, ʻoihana photovoltaic, aerospace, nā mea kaua, semiconductor, nā mea uila, nā pahū, nā pahu, nā pā lithium, etc.
Nā waiwai a me nā hiʻohiʻona o ka zirconia ceramics
ʻO Zirconia ceramics kahi ʻano hou o nā ceramics ʻenehana kiʻekiʻe, ʻo ia ka mea me ka ikaika kiʻekiʻe, ka paʻakikī, ke kūpaʻa kiʻekiʻe o ka wela, ka waikawa a me ka alkali corrosion kūpaʻa a me ke kūpaʻa kemika kiʻekiʻe a me nā kūlana ʻē aʻe, i ka manawa like me ka pale ʻana a me ka pale ʻana, ʻaʻole. hōʻailona pale, maikaʻi wela dissipation hana a me kekahi mau hiʻona, oiai ikaika machinability, maikai hiʻona hopena.
1, kiʻekiʻe heheʻe helu, kiʻekiʻe hehee ai wahi a me ka kemikala inertness hana zirconia hiki ke hoʻohana 'ia e like me ka refractory maikai;
2, me ka ʻoi aku ka paʻakikī a ʻoi aku ka maikaʻi o ka pale ʻana;
3, ʻoi aku ka nui o ka ikaika a me ka paʻakikī;
4, haʻahaʻa haʻahaʻa thermal conductivity, haʻahaʻa hoʻonui coefficient, kūpono no ka structural ceramic mea;
5, maikaʻi uila hana, mai ka shielding efficient point of view, zirconia ceramic like me non-metallic mea 'aʻohe shielding hopena ma electromagnetic hōʻailona,ʻaʻole e pili i loko o ka antenna hoʻolālā.
