Ke hoʻohālikelike nei i nā kānana Sintered keleawe a me ke kila kila: nā ʻokoʻa koʻikoʻi

1. Nā ʻano mea
Hana ʻia nā kānana sintered keleawe me ka pauka keleawe a hoʻopaʻa ʻia a sintered ʻia i nā mahana kiʻekiʻe. Kaulana ke keleawe no kona conductivity thermal a me ka uila maikaʻi loa, e lilo ia i koho kūpono no nā noi e hoʻoikaika i ka hoʻoheheʻe wela a i ʻole nā ​​​​pilina uila. Eia nō naʻe, i ka hoʻohālikelike ʻia me ke kila kila, ʻoi aku ka haʻahaʻa o ke kūpaʻa ʻana o ke keleawe i ka pala, kahi e kaupalena ai i kona hoʻohana ʻana i nā wahi pala loa.

Ma ka ʻaoʻao ʻē aʻe, hana ʻia nā kānana sintered kila kila me ka hoʻohana ʻana i ka pauka kila kila. Kaulana ke kila kila no kona kūpaʻa maikaʻi loa i ka pala, ka lōʻihi, a me ka ikaika. ʻO kēia ka mea e kūpono ai nā kānana sintered kila kila no nā kūlana ʻino, e like me ka ʻike ʻana i nā kemika, nā waikawa, a i ʻole nā ​​​​​​wahi kiʻekiʻe. Eia kekahi, hiki i ke kila kila ke kū i nā mahana hana kiʻekiʻe ma mua o ke keleawe, e hoʻonui hou ana i kāna laulā noi.

2. Ka ikaika a me ke kūpaʻa o ka mīkini
Ma ke ʻano o ka ikaika mechanical, ʻoi aku ka maikaʻi o ka hana o nā kānana sintered kila kila ma mua o nā kānana keleawe. Loaʻa i ke kila kila ka ikaika tensile maikaʻi loa, ka paʻakikī, a me ke kū'ē ʻana i ka deformation compressive. ʻOi aku ka paʻa a me ka lōʻihi o nā kānana sintered kila kila, ʻoi aku hoʻi i nā wahi ʻoihana koi e like me ka hana ʻaila a me ke kinoea, ka hana kemika, a me nā lāʻau lapaʻau.

ʻOiai ʻaʻole paʻa nā kānana sintered keleawe e like me ke kila kila, he ductility maikaʻi ko lākou a me ka hiki ke hoʻolōʻihi ʻia. ʻO kēia mau ʻano e maʻalahi ai ke hoʻohālikelike i nā kānana keleawe i ka wā o ke kaʻina hana. Eia nō naʻe, he haʻahaʻa ko lākou ikaika mechanical, ʻo ia hoʻi, ʻaʻole kūpono lākou no nā noi koʻikoʻi kiʻekiʻe.

3. Ke kū'ē ʻana i ka mahana
I ka hoʻohālikelike ʻana i kēia mau ʻano kānana ʻelua, ʻo ke kūpaʻa ʻana i ka mahana kekahi kumu nui. Hiki i nā kānana sintered kila kila ke hana pono ma nā mahana kiʻekiʻe loa ma mua o nā kānana sintered keleawe. No ka laʻana, hiki i ke kila kila ke kū i nā mahana a hiki i 1000 ° C (ma muli o ke ʻano), ʻoiai ʻo ke keleawe he kiko heheʻe ma kahi o 1085 ° C a emi nui kāna hana i nā mahana kiʻekiʻe.

ʻO kēia ʻokoʻa o ke kūpaʻa ʻana i ka mahana e hoʻolilo i nā kānana sintered kila kila i koho makemake ʻia no nā noi wela kiʻekiʻe, e like me nā ʻōnaehana kuni, ka kānana kinoea hoʻopau, a me nā mea hoʻololi wela. Eia nō naʻe, ʻoi aku ka kūpono o nā kānana sintered keleawe no nā wahi mahana waena a haʻahaʻa, kahi e hāʻawi ai kā lākou mau waiwai kūikawā e like me ka conductivity thermal i ka waiwai i hoʻohui ʻia.
