Ubucucike bwa Bentonite Slurry
1. Gutondekanya no gukora ibitutsi
1.1 Ibyiciro
Bentonite, izwi kandi ku izina rya bentonite, ni urutare rw'ibumba rugaragaza ijanisha ryinshi rya montmorillonite, rikunze kuba ririmo bike bya illite, kaolinite, zeolite, feldspar, calcite, n'ibindi. Muri byo, calcium ishingiye kuri bentonite ishobora gushyirwa mu byiciro bya calcium-sodium na calcium-magnesium ishingiye kuri bentonite, nayo.
1.2 Imikorere
1) Ibintu bifatika
Bentonite ni umweru n'umuhondo wijimye muri kamere mugihe nayo igaragara mubururu bwerurutse, umutuku wijimye wijimye, umutuku wijimye, umukara, nibindi. Bentonite iratandukanye kubera gukomera kubera imiterere yumubiri.
2) Ibigize imiti
Ibikoresho nyamukuru bigize imiti ya bentonite ni dioxyde ya silicon (SiO2), oxyde ya aluminium (Al2O3) namazi (H2O). Ibiri muri oxyde ya fer na magnesium oxyde nayo iba ndende rimwe na rimwe, kandi calcium, sodium, potasiyumu bikunze kugaragara muri bentonite mubintu bitandukanye. Ibiri muri Na2O na CaO muri bentonite bigira icyo bihindura kumiterere yumubiri nubumashini, ndetse nubuhanga bwo gutunganya.
3) Ibintu bifatika & imiti
Bentonite ihagaze neza muri hygroscopique nziza, ni ukuvuga kwaguka nyuma yo kwinjiza amazi. Umubare wagutse urimo kwinjiza amazi ugera hejuru inshuro 30. Irashobora gukwirakwizwa mumazi kugirango ibe ihagarikwa rya viscous, thixotropic, na lubricate colloidal. Ihinduka neza kandi ifata nyuma yo kuvangwa n imyanda myiza nkamazi, ibishishwa cyangwa umucanga. Irashobora gukurura imyuka itandukanye, amazi, nibintu kama, kandi ubushobozi bwa adsorption bushobora kugera ku nshuro 5 uburemere bwacyo. Ubutaka-bukora aside ihumanya isi irashobora adsorb ibintu byamabara.
Imiterere yumubiri na chimique ya bentonite ahanini biterwa nubwoko nibirimo bya montmorillonite irimo. Muri rusange, sodiyumu ishingiye kuri bentonite ifite imiterere isumba iyindi yumubiri nubumashini nubuhanga bwikoranabuhanga kuruta calcium ishingiye kuri calcium cyangwa magnesium ishingiye kuri bentonite.
2. Gupima guhoraho kwa Bentonite Slurry
UwitekaLonnmeterinlinebentoniteslurryubucucikemeteroni kumurongometero yubucucikeikoreshwa kenshi mubikorwa byinganda. Ubucucike bwa slurry bivuga ikigereranyo cyuburemere bwibisebe nuburemere bwamazi yagenwe. Ingano yubucucike bwapimwe gupimirwa kurubuga biterwa nuburemere bwuzuye bwibisumizi hamwe nuduce twa drill muri slurry. Uburemere bwimvange bugomba kubamo nabyo niba bihari.
3. Gukoresha Slurry mubihe bitandukanye bya geologiya
Biragoye gucukura umwobo muri sander, amabuye, amabuye ya kaburimbo na zone zacitse kugirango habeho guhuza ibice bito. Urufunguzo rwikibazo ruri mu kongera imbaraga zihuza ibice, kandi ifata ubunebwe nkinzitizi yo gukingira murwego nk'urwo.
3.1 Ingaruka yubucucike bwa Slurry kumuvuduko wo gucukura
Umuvuduko wo gucukura ugabanuka no kwiyongera kwinshi. Umuvuduko wo gucukura ugabanuka cyane, cyane cyane iyo ubucucike burenze 1.06-1.10 g / cm3. Iyo hejuru ya viscosity ya slurry ni, umuvuduko wo gucukura.
3.2 Ingaruka zumucanga muri Slurry kubucukuzi
Ibiri mu myanda yo mu rutare biri mu kaga bitera ingaruka ku gucukura, bikavamo umwobo usukuye nabi hanyuma ugakomeza. Byongeye kandi, irashobora gutera guswera no kwishima, bikavamo kumeneka cyangwa gusenyuka neza. Ibirimo umucanga ni muremure kandi imyanda iri mu mwobo ni ndende. Itera urukuta rw'umwobo gusenyuka bitewe na hydration, kandi biroroshye gutera uruhu rworoshye kugwa kandi bigatera impanuka mumwobo. Muri icyo gihe, ibirimo imyanda myinshi itera kwambara cyane ku miyoboro, imyanda ya drill, amaboko ya silinderi y'amazi, hamwe n'inkoni za piston, kandi ubuzima bwabo ni bugufi. Kubwibyo, hashingiwe ku kwemeza uburinganire bwumuvuduko ukabije, ubwinshi bwumucanga nibirimo umucanga bigomba kugabanuka bishoboka.
3.3 Ubucucike bwihuse mubutaka bworoshye
Mubutaka bworoshye, niba ubucucike bwa slurry buri hasi cyane cyangwa umuvuduko wo gucukura byihuse, bizatera umwobo gusenyuka. Mubisanzwe nibyiza kugumana ubucucike bwa 1.25g / cm3muri ubu butaka.
4. Inzira zisanzwe
Hariho ubwoko bwinshi bwibisebe mubuhanga, ariko birashobora gushyirwa mubwoko bukurikira ukurikije imiterere yabyo. Uburyo bwo kugereranya nuburyo bukurikira:
4.1 Na-Cmc (Sodium Carboxymethyl Cellulose) Slurry
Uku guswera nikintu gikunze kwiyongera-cyongerera imbaraga, kandi Na-CMC igira uruhare mukuzamura ubukonje no kugabanya amazi. Inzira ni: 150-200g y'ibumba ryiza cyane ryibumba, 1000ml y'amazi, 5-10Kg ivu rya soda, hamwe na 6kg ya Na-CMC. imitungo idahwitse ni: ubucucike 1.07-1.1 g / cm3, ubukonje 25-35s, gutakaza amazi munsi ya 12ml / 30min, pH agaciro ka 9.5.
4.2 Icyuma cya Chromium Umunyu-Na-Cmc Igicucu
Iyi slurry ifite imbaraga zo kongera ubukonje no gutuza, kandi umunyu wa chromium wumunyu ugira uruhare mukurinda flocculation (dilution). Inzira ni: ibumba 200g, amazi 1000ml, hafi 20% wongeyeho umuti wa alkali usukuye kuri 50%, 0.5% wongeyeho umunyu wa ferrochromium kuri 20%, na 0.1% Na-CMC. Imiterere ya slurry ni: ubucucike 1,10 g / cm3, ubukonje 25s, gutakaza amazi 12ml / 30min, pH 9.
4.3 Lignin Sulfonate Slurry
Lignin sulfonate ikomoka ku mazi ya sulfite ya pulp kandi isanzwe ikoreshwa ifatanije n’amakara ya alkali kugirango ikemure anti-flocculation n’amazi yatakaye bitewe no kwiyongera kwijimye. Amata ni ibumba 100-200 kg, 30-40kg sulfite pulp yimyanda, 10-20 kg amakara alkali, 5-10 kg NaOH, defoamer 5-10kg, namazi 900-1000L kumazi ya 1m3. Ibintu bitobora ni: ubucucike 1.06-1.20 g / cm3, ubukonje bwa funnel 18-40s, gutakaza amazi 5-10ml / 30min, na 0.1-0.3kg Na-CMC birashobora kongerwaho mugihe cyo gucukura kugirango bigabanye gutakaza amazi.
4.4 Acide Acide Slurry
Acide Humic ikoresha amakara ya alkali cyangwa sodium humate nka stabilisateur. Irashobora gukoreshwa ifatanije nubundi buryo bwo kuvura nka Na-CMC. Inzira yo gutegura acide ya humic ni ukongeramo 150-200 kg amakara ya alkali yumuriro (uburemere bwumye), 3-5kg Na2CO3, na 900-1000L amazi kuri 1m3 ya slurry. imitungo idahwitse: ubucucike 1.03-1.20 g / cm3, gutakaza amazi 4-10ml / 30min, pH 9.
