ʻO ke kaulike gula o ka thermal conductivity a me ka insulation: ka hopena o ka alumina Spherical ma ke kiʻekiʻe hoʻopiha piha.

1. Ka Papa Hana Kemika o Alumina Spherical

1.1 He aha wale nō Alumina pōʻai?

Alumina pōʻai He mea ia e lele ai i loko o nā mea hoʻokele wela- he ʻano alumini oxide (Al2O5) i hoʻololi pono ʻia i mau pōʻai kīnā ʻole, ʻaʻahu like ʻole ma o nā ʻano hana sintering. ʻAʻole like me nā pauka alumina maʻamau maʻamau e hoʻomohala ana i nā moeʻuhane a me ka hana kūpono ʻole, ʻo kēia morphology puni kahi hoʻokō o ka ʻepekema huahana. ʻAʻole ia he mea hoʻopiha wale; he hopena hoʻololi ia i hana ʻia e hoʻoponopono i kekahi o nā pilikia wela loa i loko o nā lako uila a me nā ʻōnaehana ʻoihana kiʻekiʻe. Hoʻopau ke ʻano poepoe i nā ʻaoʻao ʻāʻī e hoʻoulu ai i ka puʻu, nā mānoanoa mānoanoa, a me nā wahi nāwaliwali i loko o nā composites - e hāʻawi ana i ka assimilation seamless a me ke ʻano like ʻole. ʻAʻole kēia he hoʻonui hoʻonui; he hoʻololi paradigm e hoʻolako i nā mea hoʻolālā e pana i nā palena me ka ʻole o ka ʻae ʻana.

1.2 He aha ka Alumina pōʻai'Ike 'ia ke 'ano o ke kino?

Hoʻopili ka mea kilokilo i kona ʻano crystalline alphaphase maʻemaʻe (Al2O6), i hana pono ʻia i loko o nā pōʻai maʻemaʻe, kīnā ʻole. ʻO kēia latticework crystalline he mea paʻa i ka thermally, inert kemika, a pale ʻole i ka hoʻohaʻahaʻa ʻana i nā mahana ma mua o 1,600 °C. Aia nā ʻāpana poepoe i ka ʻili paʻa, i hoʻonui pinepine ʻia me nā lāʻau lapaʻau kūʻokoʻa e hoʻonui ai i ka hoʻohālikelike me nā polymers, epoxies, a me nā porcelains. ʻO ka mea koʻikoʻi, ʻo ka nele o nā kihi ʻoi e pale aku i ke kaumaha o loko a me nā mea hopohopo i loko o nā composites, e hōʻoia ana i nā ala wela mau. ʻAʻole maʻalahi kēia pololei atomic - pono ia no ka loaʻa ʻana o ka elusive equilibrium ma waena o ka thermal conductivity a me ka insulation uila. Ka hopena? He mea ʻaʻole e hoʻokō wale i nā kikoʻī - ʻoi aku ia ma mua o lākou me ka hilinaʻi kūpaʻa.

2. Nā ʻano kumu o ka alumina Spherical

2.1 He aha nā ʻano kino a me kemika o ka alumina Spherical?

Hāʻawi ʻo Spherical Alumina i kahi hui nui o nā hale noho e kūʻē i nā ʻano maʻamau. Ma ke kino, hāʻawi ia i ka paʻakikī Mohs o 9 (e hana ana i ke kūpaʻa abrasion), kahi helu hoʻonui wela haʻahaʻa (7– 8 × 10 ⁻⁶/ ° C), a me kahi pae conductivity wela o 25– 35 W/mK– ʻoi aku ka nui ma mua o nā insulators kumu e like me ka silica. Ma kemika, he inert, palekana, a me ka pale uila (dielectric toughness > 20 kV/mm), me ka pale ʻole i nā ʻakika, nā kumu, a me nā lewa wela kiʻekiʻe. ʻO kona ʻano spherical e hoʻemi nui i ka viscosity i nā composites, e hiki ai i ka hoʻouka ʻana o ka hoʻopiha piha (e like me 70%) me ka ʻole o ka hoʻokō ʻana i ke kaʻina hana. ʻAʻole kēia he hoʻonui huahana wale nō - he mea hoʻololi pāʻani no ka hoʻokele wela.

2.2 He aha Alumina pōʻaiNā Mea Pono?

ʻO ka hana, hana ka haku Spherical Alumina i nā ala wela maikaʻi ʻoiai e mālama ana i ka hoʻokaʻawale uila. Hoʻokumu ʻia kona geometry poepoe i ka ʻupena mānoanoa, pili pū me nā ʻāpana hoʻopihapiha kiʻekiʻe, e hiki ai i ka mahana ke hoʻopau koke me ka hoʻomohala ʻole ʻana i nā alahaka conductive. Unuhi pololei kēia i nā mea uila e holo mālie, hoʻolōʻihi i ke ola o nā huahana, a ʻaʻohe pilikia o nā kaapuni pōkole - koʻikoʻi no nā noi mana kiʻekiʻe. Hoʻohui ia, hoʻomaikaʻi ia i ka paʻakikī mechanical, ke kūpaʻa ʻana, a me ke kūpaʻa dimensional i nā pūhui, e hōʻemi ana i nā hemahema a me nā kumukūʻai mālama. No nā mea hoʻolālā, manaʻo kēia i ka hana ʻana i nā hāmeʻa i ʻoi aku ka liʻiliʻi, ka wikiwiki, a me ka palekana-ʻo nā mea āpau me ka ʻole o ka wela wela a i ʻole ka hōʻino ʻana i ka hana.

3. ʻO nā pono a me nā palena o ka alumina Spherical

3.1 He aha nā mea maikaʻi o ka Alumina Spherical?

ʻO nā pōmaikaʻi o Spherical Alumina he mea weliweli maoli. I ka hoʻomaka ʻana, loaʻa iā ia ka equilibrium gula o ka conductivity wela kiʻekiʻe (22-28 W/mK ma 70% filler) me ka insulation uila maikaʻi loa - ʻaʻole hiki i nā mea hoʻopihapiha maʻamau ke kūlike. ʻO ka lua, ʻo kāna morphology poepoe e hiki ai i ka hoʻopiha piha ʻana a hiki i 70%, e hāʻawi ana i ka 30% ʻoi aku ka maikaʻi o ka hana wela ma mua o ka alumina ʻole i ka hoʻouka like. ʻO ke kolu, hoʻemi ʻo ia i nā kumukūʻai hana ma ka hōʻemi ʻana i ka ʻōpala a me ka hoʻoponopono ʻana i ka lawelawe ʻana (ʻaʻohe koi no nā ʻano diffusion paʻakikī). ʻO ka ʻehā, hoʻonui ia i ka manaʻolana o ke ola ʻana ma o ka pale ʻana i ka luku wela - e hōʻemi ana i nā helu hemahema e like me 35% i nā noi hoʻoluhi kiʻekiʻe. ʻO ka mea hope loa, ʻo kona ʻano inert e hoʻohālikelike i nā ʻoihana āpau, mai nā mea uila uila a i ka aerospace. ʻAʻole kēia he hoʻoponopono - he hoʻololi.

3.2 He aha nā palena o ka alumina Spherical?

ʻO ke kaohi mua he uku liʻiliʻi liʻiliʻi i hoʻohālikelike ʻia me nā mea hoʻopihapiha alumina like ʻole - he mea pale i ka hoʻohālikelike ʻana i ka mālama kālā no ka wā lōʻihi. Hoʻohui, pono kāna hana ʻana i nā mea hana sintering kūikawā, e kaupalena ana i ka hiki ke komo i kekahi mau wahi. Aia kekahi ʻāpana ʻike liʻiliʻi no nā mea hoʻolako i ka hoʻonui ʻana i nā ʻāpana hana no nā ʻāpana poepoe. Eia nō naʻe, ʻoi aku ka maikaʻi o kēia mau hiʻohiʻona e ka loaʻa ʻana o ka pono o nā mea: ua hāʻule nui ka uku no ka watts o ka hoʻokele wela ma muli o ka emi ʻana o nā hemahema, ka lōʻihi o ke ola ʻana o nā mea, a me ka hana maʻalahi. No nā mea hoʻolālā noʻonoʻo i mua, he hoʻopukapuka kālā no-brainer kēia - ʻaʻole he kuʻikahi.

4. Na Wahi Alumina Spherical

Ke hoʻololi nei ʻo Spherical Alumina i nā ʻoihana kahi i hiki ʻole ai ke hoʻokele wela:

Nā mea uila: ʻO nā huahana mea hoʻohana wela (TIM) no nā kelepona paʻalima, nā LED, a me nā ʻāpana mana - mālama i nā mea hana 20% ʻoi aku ka maʻalili me ka ʻole o ka hoʻoweliweli pōkole.

Otomotite: ʻO nā ʻōnaehana hoʻoluʻu ʻana o nā ʻōnaehana kaʻa uila a me nā kukui LED kiʻekiʻe, kahi e pili pono ai ka paʻa wela i ka palekana a me ka pono.

Aerospace: ʻO nā Avionics a me nā mea ukali e kū nei i nā loli wela koʻikoʻi me ka hāʻule ʻole.

Hana Hou: ʻO nā mea hoʻopau hiki ke hoʻopaʻa ʻia no nā mea hana a me nā composites hana kiʻekiʻe i loko o nā hale hoʻoikaika ikaika.

ʻAʻole niche kēia huahana– ʻo ia ke kumu o ka hoʻolālā o nā hanauna e hiki mai ana ma ka honua holoʻokoʻa.

5. Ke Kaulike Gula: Spherical Alumina's HighFiller Ratio Breakthrough

ʻO ke akamai maoli o Spherical Alumina e hilinaʻi ana i kona hiki ke hoʻopuka i ka conductivity wela a me ka insulation i nā lakio hoʻopihapiha kiʻekiʻe - e hoʻonā i ka pilikia mau loa o ka ʻāpana. Pono nā mea hoʻopiha kuʻuna i nā kālepa hōʻoluʻolu ʻole: ʻo nā kila ke hana i ka wela akā ke kumu i nā kaapuni pōkole, ʻoiai nā insulators e like me ka silica e kaumaha i ka wela wela. Hoʻopau ka Spherical Alumina i kēia paradigm. Hoʻokumu kona ʻano poepoe i kahi ʻuenaena wela mānoanoa, pili i ka 65–70% hoʻopiha hoʻopiha, hiki i ka hoʻoili wela o 22–28 W/mK me ka mālama ʻana i ka hoʻokaʻawale uila piha.

ʻAʻole kēia no ka hoʻonaʻauao - ua hōʻoia ʻia ma ka hana. Ma nā ʻāpana LED mana kiʻekiʻe, hoʻohui ʻo Spherical Alumina i nā pae wela haʻahaʻa haʻahaʻa e 18 ° C i hoʻohālikelike ʻia me nā lāʻau lapaʻau silica, hoʻolōʻihi i ke ola ma 40% a hoʻopau i nā pani wela. No nā ʻeke ʻeke uila kaʻa, hiki iā ia ke ʻoi aku ka lahilahi a me ka māmā o nā ʻōnaehana ea e pale aku i ka wela me ka hoʻohui ʻole i ke kaumaha. Nui nā hopena: hiki ke liʻiliʻi, wikiwiki, a ʻoi aku ka ikaika o nā hāmeʻa - me ka ʻole o nā palena wela.

ʻAʻole pono nā ʻenekinia e koho ma waena o ka hana a me ka palekana a me ka palekana. Hāʻawi ka Spherical Alumina i ka equilibrium gula - kahi lawelawe kūlike kahi e noho pū ai ka hopena wela a me ka palekana uila. ʻAʻole kēia he mea waiwai wale nō; he mea hoʻoikaika i ka holomua e wehe i nā palena hou i ka hoʻolālā.

E ʻae i ke kaulike. E ʻae i ka holomua. ʻAʻole ʻo Spherical Alumina ka wā e hiki mai ana– ʻo ia ke koho āu e kali nei.

Ka mea hoʻolako

RBOSCHCO he honua hilinaʻi Alumina pōʻai mea kūʻai aku & mea hana me ka ʻoi aku o 12 mau makahiki i ka hoʻolako ʻana i nā kemika kiʻekiʻe kiʻekiʻe a me nā Nanomaterials.
