ʻO Cenospheres (Expanded Mineral Materials Containing Alumina and Silica) he huahana ia o na mea kanu puhi lanahu a he powa mama, inert, hakahaka piha i ka ea a i ole kinoea. ʻokoʻa ka waihoʻoluʻu o ka Cenosphere mai ka hina a kokoke i keʻokeʻo a ʻo kona mānoanoa ma kahi o 0.4 – 0.8 g/cm3 (0.014 – 0.029 lb./cu in), e hāʻawi ana iā lākou me ka buoyancy.
Hoʻohana ʻia nā Cenospheres ma ke ʻano he mea hoʻopihapiha māmā i loko o ke koneki a me nā plastics. Hoʻohui ʻia nā spheres me ka resin e hana i ka ʻūhā syntactic māmā i hoʻohana ʻia ma ke ʻano he kumu kumu no nā panela sandwich, nā poloka mea hana, a me ka buoyancy foam. Hoʻohana ʻia lākou e hana i nā tile refractory wela a me nā uhi seramika me ka conductivity thermal haʻahaʻa. Hoʻohui ʻia nā cenospheres i uhi ʻia metala i nā pena pale EMI.
Nā hiʻohiʻona o nā Cenospheres (i kapa ʻia hoʻiNā Microsphere Puka):
1. ʻO ka wai maikaʻi: ʻO nā microbeads puʻupuʻu he mau microspheres pōʻai āpau me ke anawaena o 0.2µm-400µm, a he ≥95% ka helu spherical, e hoʻonui ai i ka wai o ka mea i hoʻopiha ʻia a hoʻonui i ka mea i hoʻopiha ʻia no ka hana ʻana.
2. Haʻahaʻa haʻahaʻa: hollow microspheres loaʻa i ka 0. 4g/cm3 -0. 8g/cm3. Hoʻohālikelike ʻia me ka hapa nui o nā mea mineral lepo, ʻoi aku ka māmā o nā microspheres 30% -85% i ke kaumaha.
3. Kiʻekiʻe Fill Rate: Hollow microspheres noho i ka liʻiliʻi o ka ʻili e hoʻopiha ʻia. Ma muli o kona ʻano spherical, hoʻemi nui ʻia ka viscosity.
4. Ka ikaika kiʻekiʻe: hiki i nā microspheres hollow ke kū i ka 4000 kg / cm ma muli o ko lākou pūpū paʻakikī.
Ka ikaika compressive mai 3 a 7000 kg/cm3.
5. Hoʻohaʻahaʻa haʻahaʻa: ʻO nā peʻa Cavity kekahi o nā mea liʻiliʻi i loko o ke kahua hoʻopihapiha e hiki ai ke hoʻokō haʻahaʻa haʻahaʻa. ʻO ka emi ʻana o ka nui o nā microspheres hollow piha.
6.Hoʻopuʻu welaa me ke kani: ʻO ka hiʻohiʻona hollow e hana i nā microspheres puʻupuʻu i haʻahaʻa haʻahaʻa haʻahaʻa a hiki ke hoʻohana ʻia no ka hoʻohaʻahaʻa wela a me nā mea hoʻoheheʻe kani.
7. Paʻa paʻa: hiki ke hoʻohui ʻia nā microspheres hollow i nā mea hoʻoheheʻe, nā kemika kūlohelohe, ka wai, nā waikawa a i ʻole nā kumu me ka hoʻololi ʻole i kā lākou mau mea kemika.
8. Kūleʻa wela kiʻekiʻe: No ka mea he kiʻekiʻe ka helu heheʻe o nā microspheres hollow e like me 1450 ° C, hiki iā ia ke noho paʻa ma nā wela kiʻekiʻe ma luna o 1000 ° C.
9. Hoʻopili uila: E hoʻohana i nā hoʻololi uila like ʻole, nā panela mea kani, a me nā mea hoʻopili uila e hoʻomaikaʻi ai i ka hoʻopulapula.
10. Ke kumu kūʻai haʻahaʻa: ʻO ke kumukūʻai o nā microspheres hollow he 50% -200% haʻahaʻa ma mua o nā microspheres artificial.
