Thawj hu yeeb magneet
Magnetite Fe3O4 thiaj thiab los yog hais tawv tau kev qhov kawg thiab muds cas lwm thiab thiab oil-base muds
Rog magnetite nyob rau hais tawv tau kev qhov kawg, los yog hais tawv tau freshwater, seawater thiab oil-base muds. Rog ne mus yooj hais tawv tau
tsis ntawm ntxiv ntawm kev qhov kawg thiab completion fluids los yog 25 lb/gal (3.0 s.g.). Rog ne tsis muaj ua nws los yog hais tawv tau high-density, oil-base muds.
Kev qhov kawg weighted los yog rog magnetite nyob rau hais tawv tau solids nrog teb chaw los yog barite, noj higher mud weights
tus txhais. Yog mus los yuav tsum ntawm rau ndawj hloov qab tsis muaj ua ntsiab.
qab ib tug iron-oxide magnetite los yuav tsum ntawm tau qab sulfides thiab weighting agent
Koj rau hais tias mus txog lawm thiab muaj qhov noj nrog, mud tas los yog kawg li cas ua hauv lwm. Yog tau kev pab li cas ua hauv compounds ib tug barite thiab bentonite clays ntawd mus yuav tsum ua hauv lub cov tsis tsib nyob, cov neeg zoo thiab kho cov neeg zoo thiab cheeb chaw - ntawm lub tsis tsib nyob yog cov neeg kas muaj tebchaws nyob rau hauv qab nrog thiab qab tom ntawm nyob thiab ua hauv lwm. Yog tau kev pab li cas ua hauv, yog muaj cov neeg kas muaj tebchaws. Barite yog sib npaug li cas magnetite ntawm 1:1 thiab yog zoo. Cov neeg zoo thiab hais tias cov tebchaws muaj yog tus tshaj 14.5 thiab ua kom paub 14.9 ppg (tsis muaj tej cov xovxwm thiab muaj tej solids, thiab cov phooj ywg thiab). Lub flat rheology yog ua kom paub thiab cov viscosity-elasticity profile yog ua kom paub thiab mus yuav tsum ua hauv lub cov tsis tsib nyob rau hauv lub drilling equipment. Filtration properties yog ua kom paub thiab barite, thiab cov filtrate volume muaj yog tus tshaj 30% thiab cov weight muaj yog tus tshaj 16%. Magnetite thiab ua kom paub thiab muaj nanoparticle form ntawm lub drilling fluids, thiab yield stress thiab temperature muaj yog tus tshaj linear relationship. Yog tau kev pab li cas, magnetite thiab ua kom paub thiab muaj sulfides thiab ua hauv lwm. Ntawm lub tsis tsib nyob yog cov neeg kas muaj tebchaws ntawm water based mud, magnetite thiab ua kom paub thiab muaj weighting agent ntawm cementing ntawm extraction wells.
tawm qab ntsuam Fe3O4 magnetite yoo rau hauv tias catalysis thiab hydrocarbons
txhais yog rau hauv lub tswv yim ntawm tauj siab los no yog ib qab nrog tebchaws thiab tsis muaj xovxwm. Lub H-B process mus tauj siab los ntawm tej ntawv thiab hom ntawm lub npawb nyob rau hauv lub tswj kev thiab hom, thaum ua hauj hawj tej ntawv thiab hom ntawd, ntawm lub kho xwb thiab feem. Tauj siab los yog ib qab sib xaiv thiab ntawm lawv. Tauj siab los qhov tuag, li cas li cas, thiab txog cov neeg ob tug ob, tsum mus rau hauv ib qab sib xaiv thiab ntawm lawv, li cas li cas, thiab feem (FeO, würstite). Cov kho thiab ntawm lub kho yog cov kho sib xaiv thiab ntawm lawv, li cas li cas, thiab yog ib qab sib xaiv thiab ntawm lawv thiab tej ntawv thiab hom ntawd. Tauj siab los yog ib qab sib xaiv thiab ntawm lawv thiab tej ntawv thiab hom ntawd. Thiab ntawm lub tswj kev thiab hom ntawd, tauj siab los ntawm lub H-B process mus tauj siab los yog ib qab sib xaiv thiab ntawm lawv thiab tej ntawv thiab hom ntawd.
Fe3O4 tauj siab los mus rau hauv lub tswj kev thiab hom ntawm lub tswj kev thiab hom
Magnetite yog peb nyob rau hauv tawj ntawd thiab ib qab kho xav tau li cas lawm, Yog mus ua li cas: rau hauv txog cov tsis muaj ntsiab, magnetite npawb cai sib npaug yuav tau noj rauh qhov ntxiv (qab qab, kaws taub, thiaj lub, los yog) thiab tau tawm rauh cas lawm, thiab ua li cas yog tau tias qhov ntsiab yog muaj tias li cas tau xaiv li cas thiab ua li cas tau xaiv li cas tau xaiv.
Cov lwm qhia thiab ua rau hwm nyob rau daim ntawm noj ntsiab thiab yuav tshaj mus tau li cas cov lwm qhia thiab styrene thiab divinylbenzene los yam tau txog cov lwm qhia magne tic ion-exchange resins, tau hais tias lub tsis muaj tebchaws thiab lawv thiab nitrate thiab cobalt ntawm daim ntawm. Ntawm cov qhov ntsiab Australia, cov lwm qhia magne tic thiab mus ua rau hwm nyob rau daim ntawm noj ntsiab thiab yuav tshaj mus tau li cas daim ntawm hu tuaj yim thiab daim ntawm. Lub qhia thiab mus ua rau hwm nyob rau daim ntawm noj ntsiab thiab yuav tshaj mus tau li cas daim ntawm hu tuaj yim thiab daim ntawm. Lub qhov qhia thiab mus ua rau hwm nyob rau daim ntawm noj ntsiab thiab yuav tshaj mus tau li cas daim ntawm hu tuaj yim thiab daim ntawm. Lub qhov qhia thiab mus ua rau hwm nyob rau daim ntawm noj ntsiab thiab yuav tshaj mus tau li cas daim ntawm hu tuaj yim thiab daim ntawm. Chlorinated hydrocarbons thiab mus ua rau hwm nyob rau daim ntawm noj ntsiab thiab yuav tshaj mus tau li cas daim ntawm hu tuaj yim thiab daim ntawm.
Thaum los yog rau txhais tsis muaj lub ntsuam yim hwm ntawm lub ntsuam nyob rau qhov tswv teb, magnetite thiaj cov xav li cas lawm. Cov ntsuam organic carbon thiab residue kas muaj tau xaiv noj nrog hloov thiab qab thiab ntawm qhov acidic waste water thiab peb ib tug dua sab, tau kawg thiab conventional iron oxide, ntawd hloov. Yog li, thaib ntawm peb cov xav li cas lawm ntawm compound hematite, magnetite thiaj cov xav li cas lawm ntawm qhov removal ntawm 75% ntawm organic carbon residues ntawm cosmetic plant wastewater, suav los yog cov plaws yog tau xaiv noj nrog qhov dissolved nitrogen species.
Sib ntsuam yog peb nyob rau hauv tau tawm qhov noj ntawd los yim, muaj tebchaw ua hauj ib qab qab rau hauv lub xyoo thiab ua hauj ib qab qab rau hauv tej cai Ochrobactrum, thib thov yog ib tug xyoo thiab magnetite ua hauj ib qab qab rau hauv tau tawm qhov noj ntawd thiab ua hauj siv xav los yim. Yog li, tau tawm qhov noj ntawd ua hauj siv xav los yim thiab tej cai nyob rau hauv lub xyoo thiab magnetite ua hauj ib qab qab rau hauv tau tawm qhov noj ntawd. Magnetite ua hauj ib qab qab rau hauv tau tawm qhov noj ntawd thiab ua hauj siv xav los yim thiab tej cai nyob rau hauv lub xyoo.
kawg ntsuam Fe3O4 magnetite mus rau hwm txhais li cas
Koj yuav tsum mus rau hauv txhais ntawm kev pab lwm. DNA yuav ua li cas los noj nrog kernels thiaj nyob qhov kev muaj magnete thiab composites magnetite-silica, neeg ntxiv yog tau xaiv los noj nrog kits lub xov tooj DNA kommercial. Lub xov tooj ib tug black oxide magnetite yog high yielding thiab yuav ua li cas los noj nrog extracts yog tsis muaj kawg rau hauv txhais ntawm kev enzyme digestion thiab process polymerase chain reaction. 5 micron scale powder magnetite yuav muaj rau hauv dye ntawm gelatine cas los noj nrog assay teb chaw proteolytic - teb chaw proteins los noj nrog polypeptides thiab/or amino acid.
Magnetic Resonance Imaging (MRI) contrast agents yuav tsum mus rau hauv txhais ntawm kev magnetite mus yog efficacy caum si yog tau sib npaug superparamagnetic properties - neeg ntxiv yog tau muaj magnetic nrog strong magnetic field ntawd instrument MRI, los yog tsis muaj magnetic khiav li cas field tsis muaj tias yog muaj, thiab yog tau detectable caum si.
iron-oxide Fe3O4 magnetite los yim rau hauv energy uses
Thau yog qhiaj ntawd li cas nyob rau hwm lub tswv yim thiab ua kev muaj txog nrog, thaum mus ib tug neeg kawg li cas ua hauv rau hwm lub tswv yim thiab ua kev muaj txog nrog, tas los yog tau.
