     Kokua kānana diatomiteLoaʻa ka microporous maikaʻi, ka hana adsorption a me ka hana anti-compression, ʻaʻole ia e hiki ai i ka wai kānana ke loaʻa i kahi ʻoi aku ka maikaʻi o ka kahe kahe, akā e kānana pū i nā mea paʻa i hoʻopaʻa ʻia e hōʻoia i ka maopopo.

     honua diatomaceousʻo ia ka waihonao na koena o na diatoms kahiko hookahi. ʻO kona mau hiʻohiʻona: ke kaumaha māmā, ka porous, ka ikaika kiʻekiʻe, ke kūpaʻa ʻana, ka insulation, ka wela wela, ka adsorption a me ka hoʻopiha a me nā hana maikaʻi ʻē aʻe. Loaʻa ka paʻa kemika maikaʻi. He mea koʻikoʻi ʻoihana e like me ka insulation wela, wili, kānana, adsorption, anti-coagulation, demoulding, hoʻopiha, lawe a pēlā aku. Hiki ke hoʻohana nui ʻia i nā ʻoihana e like me ka metallurgy, ka ʻoihana kemika, ka mana uila, ka mahiʻai, ka mea kanu, nā mea kūkulu hale a me nā huahana insulation. Hiki ke hoʻohana ʻia e like me nā mea hoʻopihapiha hana ʻoihana no ka plastics, rubber, ceramics, a me ka hana pepa.

Hoʻokaʻawale ʻia nā kōkua kānana Diatomite i nā huahana maloʻo, nā huahana calcined a me nā huahana calcined flux e like me nā kaʻina hana like ʻole.

①Huahana maloʻo ʻO ka lepo silica maloʻo maloʻo i hoʻomaʻemaʻe ʻia, hoʻomaʻemaʻe ʻia a maloʻo i hoʻomaloʻo ʻia ma kahi mahana o 600-800 ° C, a laila pulverized. Loaʻa ka nui o kēia huahana a kūpono no ka kānana pololei. Hoʻohana pinepine ʻia me nā kōkua kānana ʻē aʻe. ʻO ka hua maloʻo he melemele māmā, akā keʻokeʻo keʻokeʻo a me ka hina hina.

②Nā huahana calcined ʻO nā mea kanu diatomite i hoʻomaʻemaʻe ʻia, maloʻo a ʻokiʻoki ʻia i loko o kahi kiln rotary, calcined ma kahi mahana o 800-1200 ° C, a laila ʻoki ʻia a hoʻokaʻawale ʻia no ka loaʻa ʻana o nā huahana calcined. Ke hoʻohālikelike ʻia me nā huahana maloʻo, ʻoi aku ka nui o ka permeability o nā huahana calcined ma mua o ʻekolu mau manawa kiʻekiʻe. ʻO nā huahana calcined ka hapa nui o ka ʻulaʻula māmā.

③ʻO nā huahana calcined FluxMa hope o ka hoʻomaʻemaʻe, hoʻomaloʻo a me ka ʻoki ʻana, hoʻohui ʻia ka diatomite maka me kahi liʻiliʻi o ka sodium carbonate, sodium chloride a me nā mea flux ʻē aʻe, a laila calcined ma kahi mahana o 900-1200 ° C. Ma hope o ka ʻohi ʻana a me ka helu ʻana a me ka hoʻohālikelike ʻana, loaʻa ka huahana calcined flux. . Hoʻonui nui ʻia ka permeability o ka huahana calcined flux, ʻoi aku ia ma mua o 20 mau manawa o ka huahana maloʻo. He keʻokeʻo ka nui o nā huahana calcined flux, a ʻulaʻula māmā ke kiʻekiʻe ka ʻike Fe2O3 a i ʻole ka liʻiliʻi o ka flux.

ʻO ka hopena kānana kōkua kānana diatomite

Hoʻokō nui ʻia ka hopena kānana o ke kōkua kānana diatomite ma o nā hana ʻekolu:

1. Sieving hopena

He hopena kānana ili kēia. Ke holo ka wai i loko o ka honua diatomaceous, ʻoi aku ka liʻiliʻi o nā pores o ka honua diatomaceous ma mua o ka nui o ka nui o nā ʻāpana haumia, i hiki ʻole ai i nā ʻāpana haumia ke hele a hoʻopaʻa ʻia. Kapa ʻia kēia hopena ʻo sieving. ʻO ka ʻoiaʻiʻo, hiki ke manaʻo ʻia ka ʻili o ka keke kānana ma ke ʻano he sieve surface me ka nui o ka pore awelika like. Ke emi mai ke anawaena o na mea pa'a ma mua o (a emi iki paha) ke anawaena o na pores o ka diatomite, e " kanana ia mai ka hooku'i 'ana i na mea paa. E hoʻokaʻawale, e pāʻani i ka hana o ka kānana ʻili.
2. Ka hopena hohonu

ʻO ka hopena hohonu ka hopena paʻa o ka kānana hohonu. Ma ka kānana hohonu, ke kaʻina hana kaʻawale wale nō i loko o ka "loko" o ka waena. Hoʻopaʻa ʻia kahi ʻāpana o nā ʻāpana haumia liʻiliʻi e komo i ka ʻili o ka keke kānana e nā ala microporous tortuous i loko o ka honua diatomaceous a me nā pores liʻiliʻi i loko o ka keke kānana. ʻOi aku ka liʻiliʻi o kēia ʻano ʻāpana ma mua o nā micropores o ka honua diatomaceous. Ke pā nā ʻāpana i ka paia o ke kahawai, haʻalele paha lākou i ke kahe wai. Eia naʻe, inā hiki ke hiki i kēia wahi e pili ana i ka ikaika inertial a me ke kū'ē o nā mea. ʻO ke kaulike, ʻano like kēia ʻano interception a me ka nānā ʻana, no ka hana mechanical. ʻO ka hiki ke kānana i nā ʻāpana paʻa e pili wale ana i ka nui pili a me ke ʻano o nā ʻāpana paʻa a me nā pores.

3.Adsorption

He ʻokoʻa loa ka hopena adsorption mai nā mīkini kānana ʻelua i luna. Hiki ke manaʻo ʻia kēia hopena ma ke ʻano he mea hoʻokalakupua electrokinetic, e hilinaʻi nui ana i ka ʻili o nā ʻāpana paʻa a me ka honua diatomaceous ponoʻī. Ke hoʻokuʻi ʻia nā ʻāpana me nā pores liʻiliʻi i loko o ka honua diatomaceous ma ka ʻili o loko o ka honua diatomaceous porous, e huki ʻia lākou e nā kumu kūʻē, a i ʻole nā ʻāpana e huki kekahi i kekahi e hana i nā pūpū a pili i ka honua diatomaceous. He hopena adsorption kēia a pau.

ʻOi aku ka paʻakikī o ka hopena adsorption ma mua o nā hopena ʻelua ma mua. Manaʻo nui ʻia ʻo ke kumu i paʻa ai nā ʻāpana paʻa liʻiliʻi ma mua o ke anawaena pore ma muli o:

(1) Nā ikaika waena (i kapa ʻia ʻo van der Waals attraction), me ka dipole mau, ka dipole i hoʻokomo ʻia a me ka dipole koke;

(2) Ke ola o Zeta hiki;

(3) Kaʻina hana hoʻololi Ion.
