Kōkua kānana honua diatomaceous/Diatomaceous
CAS #: 61790-53-2 (pauka i hoʻoheheʻe ʻia)
CAS #: 68855-54-9 (pauka calcined i hoʻohui ʻia)
Hoʻohana: Hoʻohana ʻia i ka ʻoihana hana pia, ʻoihana inu, ʻoihana lāʻau lapaʻau, hoʻomaʻemaʻe ʻana, hoʻomaʻemaʻe kō, a me ka ʻoihana kemika.
ʻAno kemika
ʻO ke ʻano kemika o ka honua diatomaceous he amorphous SiO2, aia ma ke ʻano o SiO2• nH2ʻO. SiO2ʻoi aku ma mua o 80%, a hiki i ka 94%. Loaʻa iā ia nā liʻiliʻi o Al2O3, ʻAi2O3, CaO, MgO, K2ʻO, Na2ʻO, P2O5, a me nā mea olaola, a me kekahi mau haumia metala e like me Cr a me Ba. ʻOkoʻa ka haku mele a me ka nui o nā lua lepo diatomaceous ma nā wahi like ʻole.
Nā Waiwai Kino
He keʻokeʻo, keʻokeʻo hina, hina hina, hina māmā, hina ʻeleʻele māmā, melemele māmā, a pēlā aku nā kala o ka honua diatomaceous. ； Density: 1.9~2.3g/cm3Ka nui o ka nui 0.34 ~ 0.65g / cm3; Kiko heheʻe: 1650 ℃ ~ 1750 ℃; ʻO ka ʻili kikoʻī o 19-65cm2/g; Ka nui o nā poho 0.45~0.98cm3/g; ʻO ka nui o ka omo ʻana o ka wai he 2-4 mau manawa o kona nui ponoʻī. Paʻa kemika kiʻekiʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka waikawa hydrochloric, maʻalahi ka hoʻoheheʻe ʻia i ka alkali, me nā waiwai maikaʻi loa e like me ka incompressibility pili, palupalu, insulation kani, pale ʻaʻahu, a me ke kūpaʻa wela.
Hoʻomohala a me ka Noi ʻana
ʻO ka lepo diatomaceous, ma muli o kona mau waiwai physicochemical kūikawā, ua hoʻohana nui ʻia ma ke ʻano he mea kōkua kānana, mea hoʻopihapiha hana, mea lawe catalyst, mea lawe pesticide a me nā mea hoʻouluulu, mea insulation, adsorbent, a me nā mea hoʻokeʻokeʻo.
Kōkua kānana：
Hiki ke hoʻohana ʻia ka lepo diatomaceous ma ke ʻano he kōkua kānana i ka meaʻai, lāʻau lapaʻau, a me nā ʻoihana kaiapuni. No ka laʻana, ʻo ka hoʻohana ʻana i ka kānana lepo diatomaceous i ke kaʻina hana waina hiki ke hoʻomau i ka hoʻonui ʻana i ka moena kānana, wikiwiki ka kānana, nui ka hua; Me kahi ʻili nui a me ka hiki ke adsorption ikaika, hiki iā ia ke kānana i nā ʻāpana mai 0.1 a 1.0 μm, hōʻemi i ka nalowale o ka waiʻona ma kahi o 1.4%, a hoʻomaikaʻi i nā kūlana hana hana. Hiki i nā kānana lepo diatomaceous ke hoʻomaikaʻi maikaʻi i ka maikaʻi o ka wai o ka mālama wai e kaʻapuni ana i ka loko ʻauʻau, a hiki ke mālama i ka wai a me ka uila i ka hana a me ka hoʻokele ʻana i nā loko ʻauʻau. ʻO ka lua, ua hoʻohana nui ʻia ka lepo diatomaceous i nā aila ʻai, nā wai waha lāʻau lapaʻau, a me nā ʻoihana ʻē aʻe.
Mea hoʻopili
Hoʻohana nui ʻia ka lepo diatomaceous i ka mālama ʻana i ka wai ʻino ma muli o kona mau waiwai kemika paʻa, ka hiki ke hoʻopili ikaika, ka hana kānana maikaʻi a me ka hiki ʻole ke hoʻoheheʻe ʻia i loko o kekahi waikawa ikaika. ʻO ka mālama mua ʻana o ka leachate landfill me ka hoʻohana ʻana i ke ʻano hoʻopulapula flocculation earth diatomaceous hiki ke hōʻemi mua i ka CODCr a me BOD5 i loko o ka leachate, wehe i nā mea haumia e like me SS, a hoʻohana nui ʻia no ka wai ʻino o ke kūlanakauhale, ka wai ʻino pepa, ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻino, ka wai ʻino pepehi kanaka, ka wai ʻino ʻaila, a me ka wai ʻino metala kaumaha.
ʻO mākou ka mea hoʻolako nui ma Kina, no ke kumukūʻai a i ʻole ka ʻike hou aku e hoʻokipa iā mākou ma:
