Khoom profile

Fluorgypsum yog cov khib nyiab uas muaj calcium sulfate uas tsim los ntawm cov tshuaj tiv thaiv ntawm sulfuric acid thiab fluorite hauv cov txheej txheem ntawm hydrofluoric acid. Nws yog tsuas yog los ntawm cov tuam txhab fluoride, suav nrog inorganic fluoride thiab organic fluoride ntau lawm cov nroj tsuag thiab lwm yam hydrofluoric acid ntau lawm cov nroj tsuag. Fluorite hmoov (CaF2) thiab concentrated sulfuric acid (H, SO4) yog tov nyob rau hauv ib tug tas mus li ratio (mass ratio 1: 1.3), cua sov nyob rau hauv lub teb rauv (250 C ~ 280 C), los ntawm cov tshuaj tiv thaiv (H2SO4 ntxiv rau CaFr{{ 9}}HF ntxiv rau CaSO4) los tsim hydrogen fluoride (HF) thiab calcium sulfate (CaSO4), hydrogen fluoride gas condensation collection los tsim hydrofluoric acid, cov tshuaj tiv thaiv ntawm cov khoom calcium sulfate yog gypsum, Vim nws muaj ib tug me me ntawm unreacted CaF2. , nws tseem hu ua "fluorogaster". Thaum fluoro-gypsum tawm ntawm lub reactor, cov khoom kub yog 180C-230C, thiab cov pa kub yog 800C-10000 C. Yog li ntawd, cov fluoro-gypsum tso tawm feem ntau yog anhydrous calcium sulfate, uas belongs rau. type II CaSO4.

Daim ntawv thov khoom

Raws li cov txheej txheem ntau lawm thiab kev kho mob, fluoro-gypsum tuaj yeem muab faib ua peb pawg hauv qab no:

① Qhuav gypsum. Ntawd yog, nws yog neutralized los ntawm kev sib xyaw txiv qaub hmoov thiab yog grey hmoov granular. Cov theem tseem ceeb muaj pes tsawg leeg yog anhydrite thiab me me ntawm CaF2 hais.

② ntub dej gypsum. Ua ntej, kev siv cov kua txiv qaub los yog av nplaum slurry neutralization, slurry rau hauv gypsum slurry, cov txheej txheem yog complex, cov khoom yog ib qho yooj yim rau corrosion thiab tsim cov pa phem theem nrab, - feem ntau tsis haum rau kev siv, theem muaj pes tsawg leeg yog hom II anhydrous CaSO2.

③ Yas gypsum. Lub slurry yog hloov mus rau hauv slurry los ntawm txoj kev kub ntawm gypsum, uas yog pumped mus rau lub slag teb thiab piled rau ib lub sij hawm ntawm lub sij hawm. Tom qab ntawd, cov slurry yog lawm hydrated rau hauv dihydrate gypsum, uas yog greyish dawb los yog dawb thaiv, thiab lub ntsiab theem muaj pes tsawg leeg yog sulfate.
