Daim ntawv thov tseem ceeb ntawm Manganese Sulfide

Manganese sulfide tau siv rau hauv cov hmoov metallurgy, tsis muaj zog hlau nplaum semiconductor cov ntaub ntawv, kho qhov muag, hluav taws xob, cov ntaub ntawv sib nqus thiab kev npaj siab purity manganese ntsev.

1) Ib hom manganese sulfide / carbon nanotubes cov khoom sib xyaw yog npaj. Tshwj xeeb, carbon nanotubes tau ntxiv rau cov kua qaub sib xyaw npaj los ntawm cov concentrated sulfuric acid thiab concentrated nitric acid rau kev kho ultrasonic, kom cov pa roj carbon nanotubes yog grafted nrog hydrophilic pawg, thiab tom qab ntawd tov nrog surfactants los tsim kev ncua. Tom qab ntawd, sulfur qhov chaw nrog cov amino pawg yog ntxiv kom nws hnov ​​​​mob nrog cov pab pawg ntawm carbon nanotubes. Tom qab ntawd cov manganese tau muab tso rau hauv qhov sib tov thiab xa mus rau lub reactor rau hydrothermal cov tshuaj tiv thaiv kom tau cov manganese sulfide / carbon nanotubes composite. Lub invention yog tus cwj pwm los ntawm kev siv cov dej electrolyte nyob rau hauv cov txheej txheem ntau lawm, kev siv manganese sulfide txheej carbon nanotubes tuaj yeem tswj tau qhov kev ncaj ncees ntawm cov duab ntawm cov pa roj carbon nanotubes, kev puas tsuaj rau cov raj carbon yog txo; Nyob rau tib lub sijhawm, axial kev npaj ntawm manganese sulfide raws cov pa roj carbon nanotubes nce nws qhov chaw tshwj xeeb, ua rau cov zinc ions zoo dua embedded thiab tshem tawm, nce nws cov conductivity, thiab cov khoom sib xyaw ua ke muaj qhov ua tau zoo.

2) Manganese thiab sulfur yog muab rho tawm los ntawm complex manganese ore ntawm manganese sulfide, uas yog tsim los ntawm 70 feem pua ​​-75 feem pua ​​manganese sulfide, 15 feem pua ​​-20 feem pua ​​manganese carbonate thiab 2 feem pua ​​-3 feem pua ​​manganese oxide. Cov kauj ruam tshwj xeeb ntawm txoj kev no yog raws li nram no: Compound manganese concentrate yog tau los ntawm crushing thiab sib tsoo ntawm ore thiab beneficiation, uas tau muab tso rau hauv lub reactor rau autoredox leaching. Qhov hnyav piv ntawm sulfuric acid tov rau compound manganese concentrate yog 2-10 ∶1, leaching kub yog 30 degree ~ 100 degree, thiab lub sij hawm leaching yog 30min ~ 120min. Tom qab ntawd oxidant ntxiv rau oxidation leaching, pom, thiab tshem tawm impurity ntawm cov tshuaj leaching. Cov filtrate tau txais yog electrolyzed rau electrolytic manganese hlau. Cov leaching residue yog ntxiv rau cov desulfurizer, thiab cov kuab tshuaj uas muaj cov tshuaj sulfur yog txias kom cov hlau sulfur tuaj yeem ua rau nag. Cov txheej txheem ntawm kev tsim khoom muab cov txheej txheem tshiab rau kev kho manganese cov peev txheej thiab rho tawm manganese thiab sulfur tib lub sijhawm, thiab muaj qhov zoo ntawm cov txheej txheem luv luv, txo cov kev siv hluav taws xob, txuag cov peev txheej, cov khoom lag luam siab thiab kev tiv thaiv ib puag ncig ntsuab.

3) Ib hom manganese sulfide nanorods tau npaj. Txoj kev npaj ntawm manganese sulfide nanorods yog characterized nyob rau hauv uas nws muaj xws li cov nram qab no cov kauj ruam: 1) manganese ntsev tov yog tau raws li qhov ratio ntawm manganese ntsev rau hnyav =(2-5) mmol rau ({{ 4}}) mL; 2) Cov tshuaj sulfur tau txais raws li qhov sib piv ntawm cov hmoov sulfur rau cov kuab tshuaj =(2 ~ 5) mmol rau (5 ~ 15) mL; 3) Tom qab cua sov cov manganese ntsev tov rau 100 ~ 200 degree, txhaj tshuaj sulfur, thiab ces cua sov rau 240 ~ 300 degree, kom tau ib tug tov tov, raws li cov tshuaj tiv thaiv system; 4) Tsim cov txheej txheem txhaj tshuaj: npaj tib cov tshuaj manganese ntsev raws li qib 1 raws li thawj qhov kev txhaj tshuaj, thiab npaj cov tshuaj sulfur tib yam li qib 2 raws li kev txhaj tshuaj thib ob; 5) Cov tshuaj ntsev manganese hauv thawj qhov kev txhaj tshuaj thiab cov tshuaj sulfur hauv qhov kev txhaj tshuaj thib ob yog txhaj rau hauv cov tshuaj sib xyaw hauv cov tshuaj tiv thaiv raws li; Manganese sulfide nanorods tau txais. Cov txheej txheem yog qhov yooj yim, ib puag ncig tus phooj ywg thiab muaj cov nqi tsim khoom tsawg. MnS nanorods tau txais los ntawm txoj kev no yog sib npaug, nrog qhov ntev ntawm 50 nm mus rau 400nm thiab qhov ntev-inch piv li ntawm 2∶1 txog 8∶1.
