Kokua kānana diatomite
ʻO ke kōkua kānana diatomite he microporous maikaʻi, hana adsorption a me ka hana anti compression. ʻAʻole hiki iā ia ke hana i ka wai kānana e loaʻa i kahi ratio kahe kahe maikaʻi, akā e kānana pū i nā mea paʻa i hoʻopaʻa ʻia, e hōʻoiaʻiʻo ana i ka maopopo. ʻO ka diatomite ke koena o nā diatoms kahiko. ʻO kona mau hiʻohiʻona: ke kaumaha māmā, ka porous, ka ikaika kiʻekiʻe, ke kūpaʻa ʻana, ka insulation, ka insulation thermal, adsorption a me ka hoʻopiha, etc.
ʻO ka diatomite ke koena o nā diatoms kahiko. ʻO kona mau hiʻohiʻona: ke kaumaha māmā, ka porous, ka ikaika kiʻekiʻe, ke kūpaʻa ʻana, ka insulation, thermal insulation, adsorption a me ka hoʻopiha ʻana, a me nā mea ʻē aʻe. He mea koʻikoʻi ʻoihana ia no ka wela wela, ka wili, kānana, adsorption, anticoagulation, demoulding, filling, carrier, etc. Hiki ke hoʻohana ʻia e like me ka hoʻopihapiha hana ʻoihana no ka plastics, rubber, ceramics, pepa hana, etc.
Hoʻoponopono Māhele
Hiki ke hoʻokaʻawale ʻia ke kōkua kānana diatomite i nā huahana maloʻo, nā huahana calcined a me nā huahana calcined flux e like me nā kaʻina hana like ʻole. [1]
① Hua maloʻo
Hoʻomaloʻo ʻia ka lepo maloʻo silica i hoʻomaʻemaʻe ʻia ma mua o 600 ~ 800 ° C a laila ʻoki ʻia. Loaʻa ka nui o kēia huahana a kūpono no ka kānana pololei. Hoʻohana pinepine ʻia me ka hui pū ʻana me nā mea kānana ʻē aʻe. ʻO ka hapa nui o nā hua maloʻo he melemele māmā, akā keʻokeʻo keʻokeʻo a me ka hina hina. [1]
② ʻO ka huahana calcined
Hāʻawi ʻia nā mea kanu diatomite i hoʻomaʻemaʻe ʻia, hoʻomaloʻo a ʻoki ʻia i loko o ka rotary kiln, calcined ma 800 ~ 1200 ° C, a laila ʻoki ʻia a hoʻopaʻa ʻia no ka loaʻa ʻana o nā huahana calcined. Ke hoʻohālikelike ʻia me ka huahana maloʻo, ʻoi aku ka nui o ka permeability o ka huahana calcined ma mua o ʻekolu mau manawa kiʻekiʻe. ʻO nā huahana calcined ka nui o ka ʻulaʻula māmā. [1]
③ Huahana calcined Flux
Hoʻohui ʻia ka mea hoʻomaʻemaʻe, maloʻo a ʻokiʻoki ʻia me ka liʻiliʻi o ka sodium carbonate, sodium chloride a me nā mea hoʻoheheʻe ʻē aʻe, calcined ma 900 ~ 1200 ° C, ʻoki ʻia a hoʻopaʻa ʻia no ka loaʻa ʻana o ka flux calcined. Hoʻonui ʻia ka permeability o ka huahana calcined flux, ʻoi aku ma mua o 20 mau manawa o ka huahana maloʻo. He keʻokeʻo ka hapa nui o nā huahana calcined Flux, a ʻulaʻula ʻulaʻula ke kiʻekiʻe ka ʻike Fe2O3 a liʻiliʻi paha ka nui o ka flux. [1]
kānana
Hoʻokō nui ʻia ka hopena kānana o ke kōkua kānana diatomite ma o nā hana ʻekolu:
Hana kānana
He ʻano kānana ili kēia. Ke kahe ka wai ma ka diatomite, ʻoi aku ka liʻiliʻi o ka pore o ka diatomite ma mua o ka nui o ka nui o nā ʻāpana haumia, no laila ʻaʻole hiki ke hele a mālama ʻia nā ʻāpana haumia. Kapa ʻia kēia hopena he screening. ʻO ka ʻoiaʻiʻo, hiki ke ʻike ʻia ka ʻili o ka keke kānana ma ke ʻano he ʻili pale me ka nui o ka pore awelika like. Ke emi ʻole ke anawaena o nā ʻāpana paʻa ma mua o (a i ʻole ka liʻiliʻi iki) i ke anawaena o nā pores diatomite, e "pale" ʻia nā ʻāpana paʻa mai ka hoʻokuʻu ʻana, e pāʻani ana i ke ʻano o ka kānana ʻili. [2]
Ka hopena hohonu
ʻO ka hopena hohonu ka hopena paʻa o ka kānana hohonu. I loko o ka kānana hohonu, ke kaʻina hana kaʻawale wale nō i loko o ka "loko" o ka waena. Hoʻopaʻa ʻia kekahi mau ʻāpana haumia liʻiliʻi e hele ana ma ka ʻili o ka keke kānana e nā ala microporous zigzag i loko o ka diatomite a me nā pores ʻoi aku ka maikaʻi i loko o ka keke kānana. ʻOi aku ka liʻiliʻi o ia mau ʻāpana ma mua o nā pores microporous o ka diatomite. Ke paʻi nā ʻāpana i ka paia o ke kahawai, hiki ke hoʻokaʻawale i ke kahe wai, akā inā hiki iā ia ke hoʻokō i kēia, Hoʻoholo ʻia e ke koena o ka ikaika inertia a me ke kūpaʻa i loaʻa i nā ʻāpana, ua like kēia interception a me ka hana screening i ke ʻano a pili i ka hana mechanical. ʻO ka hiki ke kānana i nā ʻāpana paʻa e pili ana i ka nui pili a me ke ʻano o nā ʻāpana paʻa a me nā pores. [2]
Adsorption
He ʻokoʻa loa ka Adsorption mai nā mīkini kānana ʻelua ma luna. ʻO ka ʻoiaʻiʻo, hiki ke noʻonoʻo ʻia kēia hopena ma ke ʻano he electrokinetic attraction, e hilinaʻi nui ʻia i ka ʻili o nā ʻāpana paʻa a me ka diatomite ponoʻī. I ka wā e hui ai nā ʻāpana me nā pores liʻiliʻi o ka diatomite me ka ʻili o loko o ka porous diatomite, ua huki ʻia lākou e nā kumu kūʻē, a i ʻole nā ʻāpana e huki kekahi i kekahi e hana i nā kaulahao a pili i ka diatomite, nona ka adsorption. [2] ʻOi aku ka paʻakikī o ka adsorption ma mua o nā mea mua ʻelua. Manaʻo nui ʻia ua paʻa nā ʻāpana paʻa liʻiliʻi ma mua o ke anawaena pore no ka mea:
(1) ʻO ka ikaika intermolecular (i kapa ʻia ʻo van der Waals attraction) e pili ana i ka hana dipole mau, ka hana dipole i hoʻokomo ʻia a me ka hana dipole transient;
(2) Ke ola o Zeta hiki;
(3) Kaʻina hana hoʻololi Ion.
