Density yeBentonite Slurry
1. Kuronga uye Kuita kwe slurry
1.1 Kuronga
Bentonite, inozivikanwawo se bentonite rock, idombo revhu rine chikamu chepamusoro-chepamusoro che montmorillonite, iyo inowanzo ine zvishoma zvishoma zvisingagoni kuverenga, kaolinite, zeolite, feldspar, calcite, etc. Pakati pavo, calcium-based bentonite inogona kuiswa mu calcium-sodium-based uye calcium-magnesium-based bentonites, zvakare.
1.2 Kuita
1) Zvinhu Zvenyama
Bentonite yakachena uye yakajeka yero mumasikirwo apo inoratidzikawo mune grey grey, chiedza chakasvibirira pink, tsvuku tsvuku, dema, etc. Bentonite inosiyana mukuoma nekuda kwehutano hwavo hwepanyama.
2) Kuumbwa Kwemakemikari
Iyo huru yemakemikari zvikamu zve bentonite isilicon dioxide (SiO2), aluminium oxide (Al2O3) uye mvura (H2O). Zvinyorwa zvesimbi oxide uye magnesium oxide zvakare yakakwirira dzimwe nguva, uye calcium, sodium, potassium inowanzovapo mu bentonite mune zvakasiyana-siyana. Izvo zviri mukati meNa2O uye CaO mu bentonite inoita mutsauko pane zvemuviri uye makemikari zvivakwa, uye kunyange process tekinoroji.
3) Physical & Chemical Properties
Bentonite inoshamisira mune yayo optimal hygroscopicity, kureva kuwedzera mushure mekutora mvura. Nhamba yekuwedzera inosanganisira kubatwa kwemvura inosvika pakakwirira kusvika ku30 nguva. Inogona kuparadzirwa mumvura kuti iite viscous, thixotropic, uye lubricate colloidal suspension. Inoshanduka inogoneka uye inonamira mushure mekusanganiswa nemarara akatsetseka senge mvura, slurry kana jecha. Iyo inokwanisa kutora akasiyana magasi, zvinwiwa, uye organic zvinhu, uye iyo yakanyanya adsorption kugona inogona kusvika kashanu uremu hwayo. Ivhu rinoita acid bleaching pasi rinokwanisa kupinza zvinhu zvine mavara.
Izvo zvemuviri uye zvemakemikari zvimiro zvebentonite zvakanyanya zvinoenderana nerudzi uye zvirimo zvemontmorillonite iyo ine. Kazhinji, sodium-based bentonite ine yepamusoro yemuviri uye makemikari zvinhu uye tekinoroji kuita kupfuura calcium-based kana magnesium-based bentonite.
2. Kuramba Kuyera kweBentonite Slurry
TheLonnmeterinlinebentoniteslurrydensitymitandeye onlinepulp density mitainowanzoshandiswa mumaindasitiri maitiro. Density of slurry zvinoreva chiyero chehuremu hweslurry kune huremu hwehuwandu hwakatarwa hwemvura. Saizi ye slurry density yakayerwa pa-saiti inoenderana nehuremu hwese hwe slurry uye drill cuttings mune slurry. Huremu hwemisanganiswa hunofanirwa kuverengerwa zvakare kana iripo.
3. Kushandiswa kweSlurry pasi peDifferent Geological Conditions
Zvakaoma kuchera gomba mujecha, matombo, matombo uye nzvimbo dzakaputsika dzejunior bonding properties pakati pezvimedu. Kiyi yedambudziko iri mukuwedzera simba rekubatanidza pakati pezvimedu, uye inotora slurry sechivharo chinodzivirira mune zvakadaro strata.
3.1 Mhedzisiro yeSlurry Density pane Drilling Speed
Iko kumhanya kwekuchera kunoderera nekuwedzera slurry density. Kumhanya kwekuchera kunoderera zvakanyanya, kunyanya kana slurry density yakakura kupfuura 1.06-1.10 g/cm.3. Iyo yakakwirira viscosity ye slurry ndeye, yakaderera iyo yekuchera kumhanya.
3.2 Mhedzisiro yeJecha Yemukati muSlurry paKuchera
Izvo zviri mukati memarara ematombo mune slurry zvinounza njodzi pakuchera, zvichikonzera maburi asina kucheneswa uye anozonamatira. Pamusoro pezvo, zvinogona kukonzera kusveta uye kumanikidza kufara, zvichikonzera kuvuza kana kudonha zvakanaka. Jecha rinenge rakakwirira uye mavhu ari mugomba akakora. Iyo inoita kuti gomba madziro kudonha nekuda kwe hydration, uye zviri nyore kukonzera slurry ganda kudonha uye kukonzera tsaona mugomba. Panguva imwecheteyo, iyo yakakwira sediment yemukati inokonzeresa kupera kwemapombi, zviboorero, maoko emasilinda epombi yemvura, uye tsvimbo dzepiston, uye hupenyu hwavo hwesevhisi hupfupi. Nokudaro, pasi pechikonzero chekuvimbisa kuenzana kwekuumbwa kwekumanikidza, slurry density uye jecha remukati rinofanira kuderedzwa zvakanyanya sezvinobvira.
3.3 Slurry Density muIvhu Rakapfava
Mumavhu akapfava, kana slurry density yakadzikira kana kumhanya kwekuchera kwakanyanyisa, zvinotungamira mukudonha kwegomba. Kazhinji zviri nani kuchengetedza slurry density pa 1.25g/cm3muvhu iri.
4. Common Slurry Formulas
Kune akawanda marudzi e slurry muinjiniya, asi anogona kuiswa mumhando dzinotevera zvichienderana nekuumbwa kwavo kwemakemikari. Iyo proportioning nzira ndeiyi inotevera:
4.1 Na-Cmc (Sodium Carboxymethyl Cellulose) Slurry
Iyi slurry ndiyo yakajairika viscosity-inosimudzira slurry, uye Na-CMC inoita basa mukuwedzera viscosity yekusimudzira uye kuderedza kurasikirwa kwemvura. Chimiro chacho ndeichi: 150-200g yevhu remhando yepamusoro slurry, 1000ml yemvura, 5-10Kg yesoda ash, uye inenge 6kg yeNa-CMC. slurry properties ndezvi: density 1.07-1.1 g/cm3, viscosity 25-35s, kurasikirwa kwemvura isingasviki 12ml/30min, pH kukosha kwe9.5.
4.2 Iron Chromium Salt-Na-Cmc Slurry
Iyi slurry ine viscosity yakasimba yekusimudzira uye kugadzikana, uye iron chromium munyu inobata basa mukudzivirira flocculation (dilution). Chimiro chacho ndeichi: 200g ivhu, 1000ml mvura, inenge 20% kuwedzera kwemvura yakachena alkali pa50% concentration, 0.5% kuwedzera kweferrochromium salt solution pa20% concentration, uye 0.1% Na-CMC. Iyo slurry zvivakwa ndeiyi: density 1.10 g/cm3, viscosity 25s, kurasikirwa kwemvura 12ml/30min, pH 9.
4.3 Lignin Sulfonate Slurry
Lignin sulfonate inotorwa kubva kune sulfite pulp tsvina yemvura uye inowanzo shandiswa musanganiswa nemarasha alkali agent kugadzirisa iyo anti-flocculation uye kurasikirwa kwemvura kweslurry pahwaro hwekuwedzera viscosity. Mushonga wacho ivhu 100-200kg, 30-40kg sulfite pulp waste liquid, 10-20kg marasha alkali agent, 5-10kg NaOH, 5-10kg defoamer, uye 900-1000L mvura ye1m3 slurry. Iyo slurry zvivakwa ndeiyi: density 1.06-1.20 g/cm3, funnel viscosity 18-40s, kurasikirwa kwemvura 5-10ml/30min, uye 0.1-0.3kg Na-CMC inogona kuwedzerwa panguva yekuchera kuti iwedzere kuderedza kurasikirwa kwemvura.
4.4 Humic Acid Slurry
Humic acid slurry inoshandisa marasha alkali agent kana sodium humate seyakagadzikana. Inogona kushandiswa pamwe chete nevamwe vamiririri vekurapa seNa-CMC. Iyo formula yekugadzirira humic acid slurry ndeyekuwedzera 150-200kg marasha alkali agent (yakaoma uremu), 3-5kg Na2CO3, uye 900-1000L mvura kusvika 1m3 yeslurry. slurry zvivakwa: density 1.03-1.20 g/cm3, kurasikirwa kwemvura 4-10ml/30min, pH 9.
