Dab tsi yog cov yam ntxwv ntawm cov khoom siv sib txhuam txhuam txhuam, koj puas to taub lawv tiag tiag? (Kub)
Cov tshuaj formula ntawm fluorite, cov khoom sib txhuam rau cov ntaub qhwv, yog CaF2, tseem hu ua fluorspar, uas yog cov ntxhia halogen, cov hmoov dawb dawb, thiab muaj qhov melting point ntawm 1360 degree, teej tug mus rau equiaxed crystal system. Fluorite los ntawm volcanic magma, hauv magma ...
Fluorite ua cov khoom sib txhuam rau cov ntaub qhwv
Cov tshuaj formula ntawm fluorite yog CaF2, tseem hu ua fluorspar, uas yog ib tug halogen ntxhia, dawb khoom hmoov, melting point 1360 degree, thiab belongs rau lub equiaxed crystal system. Fluorite los ntawm volcanic magma. Thaum lub caij txias ntawm magma, cov kua roj-dej sib cais los ntawm magma muaj ntau yam tshuaj, feem ntau yog fluorine. Thaum cov tshuaj tau nce raws cov kab nrib pleb, qhov kub thiab siab txo qis, thiab cov tshuaj fluorine hauv cov kua roj-dej Cov ions ua ke nrog calcium ions nyob rau hauv cov pob zeb nyob ib puag ncig los tsim cov calcium fluoride, uas crystallizes ntawm qhov txias kom muab fluorite. Thaum fluorite yog siv los ua cov khoom sib txhuam, nws muaj qhov zoo ntawm qhov kub thiab txias kev sib txhuam kev ua haujlwm thiab kev ua haujlwm zoo adsorption, thiab nws cov nqi qis, yog li nws tuaj yeem siv ntau dua hauv cov khoom tsim.
Recycled log tsheb hmoov cov khoom siv rau cov khoom siv nres nres
Cov log tsheb khib nyiab reclaimed roj hmab hmoov yog cais cov hlau hlau thiab fiber ntau hauv lub log tsheb los ntawm ntau yam thev naus laus zis thiab zom cov roj hmab thaiv rau hauv cov hmoov roj hmab. Hauv cov ntaub ntawv sib txhuam, cov khoom siv roj hmab hmoov feem ntau ntawm 60 thiab 100 mesh. Txij li cov hmoov roj hmab zoo dua, qhov siab dua qhov yuav tsum tau ua rau cov txheej txheem ntau lawm, tus nqi yuav siab, tab sis cov khoom zoo dua yog siv cov khoom sib txhuam. Qhov zoo dua qhov kev txhim kho ntawm qhov hnav ntawm cov khoom sib txhuam thiab nqus cov suab nrov.
