ʻO nā kōkua kānana honua diatomaceous he microporous maikaʻi, hana adsorption, a me ke kūpaʻa compressive, ʻaʻole hiki i ka wai kānana ke hoʻokō i kahi kahe kahe maikaʻi, akā kānana pū i nā mea paʻa i hoʻokuʻu ʻia, e hōʻoia i ka maopopo.ʻO ka honua diatomaceous he sediment o nā koena diatom one-celled kahiko.ʻO kona mau hiʻohiʻona e like me ka māmā, ka porous, ka ikaika kiʻekiʻe, ka lole pale, ka insulation, ka insulation, adsorption, a me ka hoʻopiha, i waena o nā waiwai maikaʻi loa.

ʻO ka honua diatomaceous he sediment o nā koena diatom one-celled kahiko.ʻO kona mau hiʻohiʻona e like me ka māmā, ka porous, ka ikaika kiʻekiʻe, ka lole pale, ka insulation, ka insulation, adsorption, a me ka hoʻopiha, i waena o nā waiwai maikaʻi loa.Loaʻa ka paʻa kemika maikaʻi.He mea waiwai nui ia no ka insulation, grinding, filtration, adsorption, anticoagulation, demolding, filling, and carrier.Hiki ke hoʻohana nui ʻia i nā ʻoihana e like me ka metallurgy, chemical engineering, uila, mahiʻai, fertilizers, kūkulu hale a me nā huahana insulation.Hiki ke hoʻohana ʻia e like me nā mea hoʻopihapiha hana ʻoihana no ka plastics, rubber, ceramics, papermaking, a me nā ʻoihana ʻē aʻe.

Hoʻokaʻawale ʻia nā kōkua kānana honua diatomaceous i nā huahana maloʻo, nā huahana calcined, a me nā huahana calcined flux e like me nā kaʻina hana like ʻole.
① Nā huahana 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 hua maloʻo he melemele māmā, akā he keʻokeʻo waiū a me ka hina hina.

② Huahana calcined
Hāʻawi ʻia ka lepo diatomaceous i hoʻomaʻemaʻe ʻia, maloʻo a ʻoki ʻia i loko o kahi kiln rotary, calcined ma kahi mahana o 800-1200 ° C, a laila ʻoki ʻia a hoʻopaʻa ʻia no ka loaʻa ʻana o ka 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 nui o ka ʻulaʻula māmā.

③ Nā huahana calcined Flux
Ma hope o ka hoʻomaʻemaʻe ʻana, ka maloʻo ʻana, a me ka ʻoki ʻana, hoʻohui ʻia ka honua diatomaceous me kahi liʻiliʻi o nā mea fluxing e like me ka sodium carbonate a me ka sodium chloride, a calcined ma kahi mahana o 900-1200 ° C. Loaʻa ka huahana calcined flux.Ua hoʻonui nui ʻia ka permeability o nā huahana calcined flux, ʻoi aku ia ma mua o 20 mau manawa o nā huahana maloʻo.He keʻokeʻo ka hapa nui o nā huahana calcined o ka flux, a ke kiʻekiʻe ka ʻike Fe2O3 a i ʻole ka haʻahaʻa o ka flux, ʻike ʻia ka ʻulaʻula māmā.

ʻO nā hemahema nui o nā kōkua kānana honua diatomaceous:

1. Ka nele i nā kumuwaiwai.ʻO ka hana ʻana i nā mea kānana honua diatomaceous e pono ai ka honua diatomaceous kiʻekiʻe me ka ʻike diatom kiʻekiʻe.ʻOiai he nui nā kumu honua diatomaceous o Kina, ʻo ka hapa nui he mau mines honua diatomaceous haʻahaʻa haʻahaʻa, he paʻakikī ke hoʻokō i nā koi hana;

2. He kiʻekiʻe ke kumukūʻai hana.ʻO ke kaʻina hana o ka honua diatomaceous he mea paʻakikī, a hui pū me ke kumukūʻai kiʻekiʻe o nā kumu waiwai honua diatomaceous kiʻekiʻe, ua mālamaʻia ke kumukūʻai o nā kōkua kānana honua diatomaceous ma Kina i kahi kiʻekiʻe;

3. He lohi ka filtration rate a he kiʻekiʻe ka nui.ʻO ka hoʻohui ʻana i nā mea hou aku e like me kona maikaʻi pinepine ʻaʻole i kūpono i nā koi i manaʻo ʻia, a ʻo ka hoʻohui hou ʻana e hoʻonui i ke kumukūʻai.Makemake kekahi poʻe e hoʻomohala i nā huahana ʻano honua diatomaceous me ka haʻahaʻa haʻahaʻa haʻahaʻa, akā ma muli o nā palena o ka haku mele ʻana a me ke ʻano o nā mea maka, ʻaʻole i loaʻa nā hopena maikaʻi i kēia manawa;

4. ʻAʻole kūpono ka paʻa kemika.ʻO ka ʻike o nā mea ʻino e like me ka hao a me ka calcium i loko o ka honua diatomaceous he kiʻekiʻe a noho i kahi kūlana kaʻawale, no laila ua kiʻekiʻe kona dissolution rate.Ke kānana ʻana i nā mea inu a me nā mea inu ʻawaʻawa, hiki i ka hoʻoheheʻe hao kiʻekiʻe ke hoʻopilikia i ka ʻono a me ka ʻono o ka huahana.
