Txhawm rau txhim kho kev xaiv cov txheej txheem (txhim kho cov txiaj ntsig thiab cov neeg sawv cev ua npuas dej uas muaj txiaj ntsig zoo ntawm cov roj hmab, cov tswj hwm feem ntau siv hauv cov txheej txheem frotation. Cov kev kho hauv cov txheej txheem frotation suav nrog ntau cov tshuaj lom neeg. Raws li lawv lub luag haujlwm hauv cov txheej txheem frolotation, lawv tuaj yeem faib ua cov neeg tsis muaj yeeb yaj kiab, cov neeg sawv cev hauv nruab nrab, cov neeg sawv cev nruab nrab, discidants, thiab lwm yam.
Thaum lub sijhawm flotation flotation, inhibitors yog cov neeg sawv cev uas tuaj yeem tiv thaiv lossis txo cov zaub mov tsis yog-fydrophilic zaj duab xis nyob rau saum npoo ntawm cov merals.
Sodium oxide inhibitor yog ib qho tseem ceeb inhibitors hauv cov txheej txheem frolotation.
Yuav ua li cas sodium oxide inhomitors ua haujlwm
Lub hauv paus ntsiab lus tom qab siv cov sodium oxide (NA2O) ua tus neeg nyob hauv cov ntxhia pob zeb cuam tshuam nrog nws cov tshuaj lom neeg thiab kev sib cuam tshuam nrog cov ntxhires chaw. Kab lus no yuav qhia tau meej cov qauv molecular, cov mis mos, tshuaj lom neeg thiab Inhibition tshuab.
Molecular qauv thiab tshuaj siv tshuaj
Cov tshuaj siv tshuaj lom neeg ntawm cov sodium oxide yog na2o, uas yog ib qho sib txuas ntawm Sodium ions (NA ^ +) thiab OX ^ 2-). Hauv cov ntxhia freatation, lub ntsiab muaj nuj nqi ntawm sodium oxide yog ua kom muaj cov pa ntawm cov ntxhia thiab inhibiting lub flotation ntawm qee cov minerals.
Daim ntawv thov thiab cov ntsiab cai ntawm sodium oxide hauv cov ntxhia flotation
1. Nto Oxidation
Thaum lub sij hawm cov txheej txheej ntxhia ntxig, sodium oxide tuaj yeem yauv tawm cov tshuaj tiv thaiv oxidation nrog cov nplaim taws me me. Qhov kev tawm tsam no feem ntau cuam tshuam nrog sodium oxide reacting nrog oxide lossis hydroxides ntawm cov ntxhia saum npoo av uas tabkaum lub flotation ntawm cov ntxhia.
Piv txwv li, ntawm cov npoo hlau (xws li fe2o3 lossis Fe (Oh) 3), sodium oxide tuaj yeem hnov Sodium hlau oxides, xws li Nafeo2:
2Na2o + + Fe2O3 → 2NAFeo2
or
2Na2o + + 2Fe (Oh) 3 → 2NAFEo2 + 3H2o
Cov kev tawm tsam no ua rau muaj cov tshuaj hlau hlau kom tau them nrog cov neeg ua haujlwm (xws li txo nws cov kab ke), txo nws cov kev ua tau zoo, thiab ua tiav kev cuam tshuam hlau.
2. PHEEJ Meej
Qhov sib ntxiv ntawm sodium oxide tuaj yeem tuaj yeem kho cov pH tus nqi ntawm cov flotation system. Muaj qee kis, hloov cov ph hniav daws yuav cuam tshuam rau cov yam ntxwv them nqi thiab tshuaj ntawm cov ntxhia, yog li cuam tshuam cov ntxhia xaiv thaum lub sij hawm flotation. Piv txwv li, hauv frolotation ntawm tooj liab cov zaub mov, tsim nyog p Phaj Phaj yog qhov tseem ceeb heev yuav inhibit cov flotation ntawm lwm cov neeg los ntawm lwm cov neeg uas tsis huv.
3. Kev xaiv tsis pub cuam tshuam ntawm cov zaub mov tshwj xeeb
Cov inisabitos nyhuv ntawm sodium oxide feem ntau yog xaiv thiab tuaj yeem ua tiav kev cuam tshuam los ntawm cov zaub mov tshwj xeeb. Piv txwv li, qhov kev cuam tshuam cov mineral hlau yog qhov zoo dua vim tias cov tshuaj tiv thaiv hlau oxide yog qhov muaj zog tau ua tau zoo nrog tus neeg sawv cev flotation.
4. Qhov xwm txheej cuam tshuam rau cov tshuab inhibition inhibition
Qhov ua tau zoo ntawm sodium oxide ua ib tug neeg inhibitor tau cuam tshuam los ntawm ntau yam kev daws teeb meem, cov nqi ntawm cov kev daws teeb meem ntawm cov kev daws teeb meem, thiab lwm yam kev ua haujlwm thaum lub sijhawm flotation. Cov kev ua haujlwm no ua haujlwm ua ke los txiav txim siab lub inisitia cov nyhuv thiab haumab muaj peev xwm ntawm sodium oxide hauv qhov chaw ua kom sov.
Ntsiab lus thiab daim ntawv thov kev cia siab
Raws li kev inhibitor hauv ntxhia ntxig, sodium oxide oxide coects nrog cov pob zeb hauv av los hloov nws cov khoom av, yog li ua tiav kev xaiv tsis pub cuam tshuam ntawm cov zaub mov tshwj xeeb. Nws cov tshuab kev nqis tes cuam tshuam nrog kev hloov pauv oxidation sib txawv, pH hloov kho thiab cuam tshuam rau cov ntxhia cov khoom siv. Nrog rau kev tshawb nrhiav hauv qhov tob tob tob tob ntawm cov ntxaij flotation kev tshawb xav thiab thev naus laus zis, muab cov kev ua haujlwm thiab cov kev daws teeb meem ntau ntxiv.
Qhov kev sib xyaw ua ke ntawm kev tshawb xav thiab kev coj ua muab cov ntxhia flotation flotation engilitors kom ua rau muaj kev ua kom zoo dua cov ntxhia rov qab thiab cov khoom lag luam zoo.
