ʻO ka Density o Bentonite Slurry
1. Hoʻokaʻawale a me ka hana o ka slurry
1.1 Hoʻokaʻawale
ʻO Bentonite, i kapa ʻia ʻo ka pōhaku bentonite, he pōhaku pālolo e hōʻike ana i ka pākēneka kiʻekiʻe o ka montmorillonite, i loaʻa pinepine i kahi liʻiliʻi o ka illite, kaolinite, zeolite, feldspar, calcite, etc. Hiki ke hoʻokaʻawale ʻia ʻo Bentonite i ʻekolu mau ʻano: bentonite-based bentonite ( lepo alkaline), ʻo ka lepo calcium-based bentonite a me ka lepo kūlohelohe (ʻo ka lepo calcium-based bentonite). Ma waena o lākou, hiki ke hoʻokaʻawale ʻia ka bentonite i hoʻokumu ʻia i ka calcium-sodium a me ka calcium-magnesium-based bentonites.
1.2 Hana
1) Nā Pono Kino
He keʻokeʻo ʻo Bentonite a he melemele māmā ma ke ʻano maoli a ʻike pū ʻia me ka hina hina, ʻulaʻula ʻōmaʻomaʻo, ʻulaʻula ʻulaʻula, ʻeleʻele, a pēlā aku.
2) Hoʻohui Kimia
ʻO nā mea kemika nui o ka bentonite he silicon dioxide (SiO2), alumini oxide (Al2O3) a me ka wai (H2O). He kiʻekiʻe ka ʻike o ka hao hao a me ka magnesium oxide i kekahi manawa, a ʻo ka calcium, ka sodium, a me ka potassium ke loaʻa pinepine i ka bentonite i nā ʻano ʻokoʻa. ʻO ka maʻiʻo o 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) Ke Kino & Kemika
ʻOi aku ka maikaʻi o Bentonite i kona hygroscopicity maikaʻi loa, ʻo ia hoʻi ka hoʻonui ʻana ma hope o ka lawe ʻana i ka wai. ʻO ka helu hoʻonui e pili ana i ka lawe ʻana i ka wai hiki ke kiʻekiʻe i 30 mau manawa. Hiki ke hoʻopuehu ʻia i loko o ka wai e hana i kahi hoʻokuʻu colloidal viscous, thixotropic, a lubricate. Hiki ke malleable a hoʻopili ma hope o ka hui ʻana me nā ʻōpala maikaʻi e like me ka wai, slurry a i ʻole ke one. Hiki iā ia ke komo i nā kinoea like ʻole, nā wai, a me nā mea kūlohelohe, a hiki i ka nui o ka adsorption hiki ke piʻi i 5 mau manawa o kona kaumaha. Hiki i ka honua hoʻomaʻemaʻe waiʻawaʻawa 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 ʻike o ka montmorillonite i loko. Ma keʻano laulā, ʻoi aku ka maikaʻi o ka bentonite i hoʻokumu ʻia i ka sodium ma mua o ka bentonite i hoʻokumu ʻia i ka calcium a i ʻole ka magnesium.
2. Ana mau o Bentonite Slurry
ʻO kaLonnmeterinlinebentoniteslurrymānoanoamikahe pūnaewelemīkini mika pulupuluhoʻohana pinepine ʻia i nā hana ʻoihana. ʻO ka mānoanoa o ka slurry e pili ana i ka ratio o ke kaumaha o ka slurry i ke kaumaha o ka nui o ka wai. ʻO ka nui o ka slurry density i ana ʻia ma ka pūnaewele ma muli o ke kaumaha o ka slurry a me nā ʻoki ʻoki i loko o ka slurry. Pono e hoʻokomo pū ʻia ke kaumaha o nā mea hoʻohui inā loaʻa.
3. Hoʻohana i ka Slurry ma lalo o nā kūlana Geological ʻokoʻa
He mea paʻakikī ke wili ʻana i lua ma ka sander, ka ʻiliʻili, ka ʻiliʻili a me nā ʻāpana haʻihaʻi no nā waiwai hoʻopaʻa liʻiliʻi ma waena o nā ʻāpana. Aia ke kī o ka pilikia ma ka hoʻonui ʻana i ka ikaika hoʻopaʻa ma waena o nā ʻāpana, a lawe i ka slurry ma ke ʻano he pale pale ma ia ʻano.
3.1 Ka hopena o ka Slurry Density i ka wikiwiki o ka wili ʻana
Ke emi nei ka wikiwiki o ka wili ʻana me ka piʻi ʻana o ka slurry density. Hoʻemi nui ka wikiwiki o ka wili ʻana, ʻoi aku ka nui o ka nui o ka slurry ma mua o 1.06-1.10 g/cm3. ʻO ke kiʻekiʻe o ka viscosity o ka slurry, ʻoi aku ka haʻahaʻa o ka wikiwiki wili.
3.2 Ka hopena o ke one ma ka Slurry ma ka wili ana
ʻO ka maʻiʻo o ka ʻōpala pōhaku i loko o ka slurry ke pilikia i ka wili ʻana, ka hopena i nā lua i hoʻomaʻemaʻe pono ʻole ʻia a hoʻopaʻa ʻia. Eia kekahi, hiki ke hoʻoulu ʻia ka hoʻoheheʻe ʻana a me ke kaomi ʻana, ka hopena i ka leakage a i ʻole ka hiolo maikaʻi. He kiʻekiʻe ke one a mānoanoa ka sediment i loko o ka lua. He mea ia e hiolo ai ka paia o ka puka ma muli o ka hydration, a he maʻalahi ka hāʻule ʻana o ka ʻili slurry a hoʻopilikia i ka lua. I ka manawa like, ʻo ka nui o ka sediment content ka mea e hoʻohana nui ai i nā paipu, nā ʻāpana drill, nā lima pahu pahu wai, a me nā lāʻau piston, a pōkole ko lākou ola lawelawe. No laila, ma lalo o ka manaʻo o ka hōʻoia ʻana i ke koena o ke kaomi hoʻokumu ʻana, pono e hoʻemi ʻia ka nui o ka slurry a me ke one ma ka hiki.
3.3 Slurry Density i loko o ka lepo palupalu
Ma nā papa lepo palupalu, inā haʻahaʻa loa ka slurry density a i ʻole ka wikiwiki o ka wili ʻana, e alakaʻi ia i ka hāʻule ʻana o ka lua. ʻOi aku ka maikaʻi o ka mālama ʻana i ka slurry density ma 1.25g/cm3ma keia papa lepo.
4. Nā ʻōkuhi Slurry maʻamau
Nui nā ʻano slurry i ka ʻenekinia, akā hiki ke hoʻokaʻawale ʻia i loko o nā ʻano aʻe e like me kā lākou hana kemika. ʻO ke ʻano hoʻohālikelike penei:
4.1 Na-Cmc (Sodium Carboxymethyl Cellulose) Slurry
ʻO kēia slurry ka slurry hoʻonui viscosity maʻamau, a ʻo Na-CMC ke kuleana i ka hoʻonui ʻana i ka viscosity a me ka emi ʻana o ka wai. ʻO ke kumu: 150-200g o ka lepo slurry kiʻekiʻe, 1000ml wai, 5-10Kg o ka lehu soda, a ma kahi o 6kg o Na-CMC. slurry waiwai mea: density 1.07-1.1 g/cm3, viscosity 25-35s, ka wai poho ma lalo o 12ml/30min, pH waiwai e pili ana i 9.5.
4.2 Hao Chromium Paakai-Na-Cmc Slurry
Keia slurry ua ikaika viscosity hoʻonui a me ka paʻa, a me ka hao chromium paʻakai pāʻani i ka pale 'ana i ka flocculation (dilution). ʻO ke kumu: 200g pālolo, 1000ml wai, ma kahi o 20% ka hoʻohui ʻana o ka solution alkali maʻemaʻe ma 50% ka nui, 0.5% ka hoʻohui ʻana o ka paʻakai paʻakai ferrochromium ma 20% ka nui, a me 0.1% Na-CMC. ʻO nā waiwai slurry: density 1.10 g/cm3, viscosity 25s, wai poho 12ml/30min, pH 9.
4.3 Lignin Sulfonate Slurry
Loaʻa ʻia ka Lignin sulfonate mai ka wai ʻōpala pulp sulfite a hoʻohana maʻamau i ka hui pū ʻana me ka lānahu alkali agent e hoʻonā i ka anti-flocculation a me ka nalowale o ka wai o ka slurry ma ke kumu o ka hoʻonui viscosity. He 100-200kg ka pālolo, 30-40kg sulfite pulp waste wai, 10-20kg lanahu alkali agent, 5-10kg NaOH, 5-10kg defoamer, a me 900-1000L wai no 1m3 slurry. ʻO nā waiwai slurry ʻo: density 1.06-1.20 g/cm3, funnel viscosity 18-40s, wai poho 5-10ml/30min, a me 0.1-0.3kg Na-CMC hiki ke hoʻohui ʻia i ka wā wili e hōʻemi hou i ka wai.
4.4 Humic Acid Slurry
Hoʻohana ka humic acid slurry i ka lānahu alkali a i ʻole ka sodium humate ma ke ʻano he stabilizer. Hiki ke hoʻohana pū ʻia me nā mea lapaʻau ʻē aʻe e like me Na-CMC. ʻO ke kumu hoʻomākaukau no ka hoʻomākaukau ʻana i ka slurry acid humic e hoʻohui i ka 150-200kg coal alkali agent (dry weight), 3-5kg Na2CO3, a me 900-1000L wai i 1m3 o ka slurry. slurry waiwai: density 1.03-1.20 g/cm3, wai poho 4-10ml/30min, pH 9.
