Ka nui o ka slurry Bentonite
1. Ka Hoʻokaʻawale ʻana a me ka Hana ʻana o ka slurry
1.1 Hoʻokaʻawale ʻana
ʻO Bentonite, i ʻike ʻia hoʻi he pōhaku bentonite, he pōhaku lepo ia me ka pakeneka kiʻekiʻe o ka montmorillonite, nona ka hapa liʻiliʻi o ka illite, kaolinite, zeolite, feldspar, calcite, a pēlā aku. Hiki ke hoʻokaʻawale ʻia ʻo Bentonite i ʻekolu ʻano: bentonite sodium-based (lepo alkaline), bentonite calcium-based (lepo alkaline) a me ka honua hoʻokeʻokeʻo kūlohelohe (lepo acidic). I waena o lākou, hiki ke hoʻokaʻawale ʻia ka bentonite calcium-based i nā bentonites calcium-based sodium a me calcium-magnesium-based.
1.2 Hana
1) Nā Waiwai Kino
He keʻokeʻo a he melemele māmā ka Bentonite i ke ʻano maoli ʻoiai ke ʻike ʻia nei hoʻi i ka hina māmā, ka poni ʻōmaʻomaʻo māmā, ka ʻulaʻula ʻeleʻele, ka ʻeleʻele, a pēlā aku. ʻOkoʻa ka ʻoʻoleʻa o ka Bentonite ma muli o ko lākou mau waiwai kino.
2) Ka Hoʻohui Kemika
ʻO nā mea kemika nui o ka bentonite ʻo ia ka silicon dioxide (SiO2), ka alumini oxide (Al2O3) a me ka wai (H2O). Kiʻekiʻe nō hoʻi ka nui o ka hao oxide a me ka magnesium oxide i kekahi manawa, a loaʻa pinepine ka calcium, sodium, potassium i loko o ka bentonite i nā ʻano like ʻole. ʻO ka nui o ka Na2O a me CaO i loko o ka bentonite e hoʻololi i nā waiwai kino a me nā kemika, a me ka ʻenehana hana.
3) Nā Waiwai Kino a me nā Kemika
ʻOi aku ka maikaʻi o ka Bentonite ma kona hygroscopicity kūpono, ʻo ia hoʻi ka hoʻonui ʻana ma hope o ka omo ʻana o ka wai. Hiki i ka helu hoʻonui e pili ana i ka omo ʻana o ka wai a hiki i 30 mau manawa. Hiki ke hoʻopuehu ʻia i loko o ka wai e hana i kahi wai hoʻoheheʻe colloidal viscous, thixotropic, a lubricate. Lilo ia i mea palupalu a hoʻopili ma hope o ka hui ʻana me nā ʻōpala liʻiliʻi e like me ka wai, slurry a i ʻole ke one. Hiki iā ia ke omo i nā kinoea like ʻole, nā wai, a me nā mea organik, a hiki i ka hiki ke hoʻopili i ka nui o ka hiki ke piʻi i 5 mau manawa o kona kaumaha. Hiki i ka honua hoʻokeʻokeʻo waikawa hana-ʻili ke hoʻopili i nā mea kala.
ʻO nā waiwai kino a me nā kemika o ka bentonite e hilinaʻi nui ʻia i ke ʻano a me ka nui o ka montmorillonite i loko. Ma keʻano laulā, ʻoi aku ka maikaʻi o nā waiwai kino a me nā kemika o ka bentonite sodium a me ka hana ʻenehana ma mua o ka bentonite calcium a magnesium paha.
2. Ke ana mau ʻana o ka Bentonite Slurry
ʻO kaAnakahi Lonni loko o ka lainabentʻoniteslʻūyka nui o ka paʻamikahe pūnaeweleana o ka mānoanoa o ka pulphoʻohana pinepine ʻia i nā kaʻina hana ʻoihana. ʻO ka nui o ka slurry e pili ana i ka lakio o ke kaumaha o ka slurry i ke kaumaha o kahi nui o ka wai i kuhikuhi ʻia. ʻO ka nui o ka nui o ka slurry i ana ʻia ma kahi e pili ana i ka nui o ke kaumaha o ka slurry a me nā ʻokiʻoki wili i loko o ka slurry. Pono e hoʻokomo pū ʻia ke kaumaha o nā mea hoʻohui inā he.
3. Hoʻohana ʻia ʻana o ka Slurry ma lalo o nā Kūlana Geological like ʻole
He mea paʻakikī ke wili i kahi lua i loko o ke one, ka ʻiliʻili, nā papa ʻiliʻili a me nā wahi i haki ʻia no nā waiwai hoʻopili liʻiliʻi ma waena o nā ʻāpana. ʻO ke kī i ka pilikia aia ma ka hoʻonui ʻana i ka ikaika hoʻopili ma waena o nā ʻāpana, a lawe i ka slurry ma ke ʻano he pale pale i loko o ia mau papa.
3.1 Hopena o ka Density Slurry i ka wikiwiki o ka ʻeli ʻana
E emi ana ka wikiwiki o ka ʻeli ʻana me ka piʻi ʻana o ka nui o ka slurry. E emi nui ana ka wikiwiki o ka ʻeli ʻana, ʻoiai inā ʻoi aku ka nui o ka slurry ma mua o 1.06-1.10 g/cm3ʻO ke kiʻekiʻe o ka mānoanoa o ka slurry, ʻo ka haʻahaʻa o ka wikiwiki o ka ʻeli ʻana.
3.2 Hopena o ka ʻIke o ke One i loko o ka Slurry ma ka ʻEli ʻana
ʻO ka nui o nā ʻōpala pōhaku i loko o ka slurry e hoʻopilikia i ka ʻeli ʻana, e hopena ana i nā lua i hoʻomaʻemaʻe pono ʻole ʻia a ma hope iho e paʻa ai. Eia kekahi, hiki ke hana i ka omo a me ke kaomi ʻana, e hopena ana i ka leakage a i ʻole ka hiolo ʻana o ka lua. Kiʻekiʻe ka nui o ke one a mānoanoa ka sediment i loko o ka lua. Hoʻoulu ia i ka hiolo ʻana o ka paia o ka lua ma muli o ka hydration, a he mea maʻalahi ke kumu i ka hāʻule ʻana o ka ʻili slurry a hana i nā pōpilikia i loko o ka lua. I ka manawa like, ʻo ka nui o ka sediment e hoʻoulu ai i ka ʻaʻahu nui ʻana i nā paipu, nā ʻāpana wili, nā lima cylinder pump wai, a me nā koʻokoʻo piston, a he pōkole ko lākou ola lawelawe. No laila, ma lalo o ke kumumanaʻo o ka hōʻoia ʻana i ke kaulike o ke kaomi hoʻokumu, pono e hoʻemi ʻia ka nui o ka slurry a me ka nui o ke one i ka hiki.
3.3 Ka nui o ka lepo i loko o ka lepo palupalu
I loko o nā papa lepo palupalu, inā haʻahaʻa loa ka nui o ka slurry a i ʻole wikiwiki loa ka wikiwiki o ka ʻeli ʻana, e alakaʻi ia i ka hiolo ʻana o ka lua. ʻOi aku ka maikaʻi o ka mālama ʻana i ka nui o ka slurry ma 1.25g/cm3ma kēia papa lepo.
4. Nā ʻano hana slurry maʻamau
Nui nā ʻano slurry i loko o ka ʻenekinia, akā hiki ke hoʻokaʻawale ʻia i loko o kēia mau ʻano e like me kā lākou hoʻohui kemika. ʻO ke ʻano hoʻohālikelike penei:
4.1 Na-Cmc (Sodium Carboxymethyl Cellulose) Slurry
ʻO kēia slurry ka slurry hoʻonui viscosity maʻamau, a he kuleana ko Na-CMC i ka hoʻonui hou ʻana i ka viscosity a me ka hōʻemi ʻana i ka nalowale o ka wai. ʻO ke ʻano hana: 150-200g o ka lepo slurry kiʻekiʻe, 1000ml o ka wai, 5-10Kg o ka lehu soda, a ma kahi o 6kg o Na-CMC. ʻO nā waiwai slurry: density 1.07-1.1 g/cm3, viscosity 25-35s, nalowale wai ma lalo o 12ml/30min, waiwai pH ma kahi o 9.5.
4.2 Hao Chromium Paʻakai-Na-Cmc Slurry
Loaʻa i kēia slurry ka hoʻonui ikaika ʻana i ka viscosity a me ke kūpaʻa, a he kuleana ko ka paʻakai hao chromium i ka pale ʻana i ka flocculation (dilution). ʻO ke ʻano hana: 200g pālolo, 1000ml wai, ma kahi o 20% hoʻohui o ka hopena alkali maʻemaʻe ma 50% concentration, 0.5% hoʻohui o ka hopena paʻakai ferrochromium ma 20% concentration, a me 0.1% Na-CMC. ʻO nā waiwai slurry: density 1.10 g/cm3, viscosity 25s, pohō wai 12ml/30min, pH 9.
4.3 Lignin Sulfonate Slurry
Loaʻa ka Lignin sulfonate mai ka wai ʻōpala pulp sulfite a hoʻohana nui ʻia me ka mea hoʻohuihui alkali lanahu e hoʻoponopono i ka anti-flocculation a me ka nalowale wai o ka slurry ma ke kumu o ka hoʻonui ʻana o ka viscosity. ʻO ke ʻano hana he 100-200kg pālolo, 30-40kg wai ʻōpala pulp sulfite, 10-20kg mea hoʻohuihui alkali lanahu, 5-10kg NaOH, 5-10kg defoamer, a me 900-1000L wai no 1m3 slurry. ʻO nā waiwai slurry: density 1.06-1.20 g/cm3, funnel viscosity 18-40s, nalowale wai 5-10ml/30min, a hiki ke hoʻohui ʻia he 0.1-0.3kg Na-CMC i ka wā e ʻeli ana e hōʻemi hou aku i ka nalowale wai.
4.4 Pāpaʻi ʻakika Humic
Hoʻohana ka slurry waikawa humic i ka mea alkali lanahu a i ʻole ka sodium humate ma ke ʻano he mea hoʻopaʻa. Hiki ke hoʻohana ʻia me nā mea lapaʻau ʻē aʻe e like me Na-CMC. ʻO ke ʻano no ka hoʻomākaukau ʻana i ka slurry waikawa humic, ʻo ia ka hoʻohui ʻana i 150-200kg mea alkali lanahu (kaumaha maloʻo), 3-5kg Na2CO3, a me 900-1000L wai i 1m3 o ka slurry. nā waiwai slurry: density 1.03-1.20 g/cm3, pohō wai 4-10ml/30min, pH 9.
