Fluorine gypsum yog ib yam khoom los ntawm hydrofluoric acid, uas yog tsim los ntawm calcium sulfate. Hydrofluoric acid yog tsim los ntawm cov tshuaj tiv thaiv ntawm sulfuric acid thiab fluoride.
Qhov zoo ntawm fluorine gypsum yog raws li tshuab:
A. Kev ua haujlwm hauv xov tooj cua ntawm fluorine gypsum yog qis dua li lub teb chaws tus qauv.
B. Cov ntsiab lus ntawm HF yog qhov ruaj khov ntawm 180-230 degrees thaum fluorine gypsum tsim, thaum hydrogen fluoride tsis tshua muaj zog nyob rau hauv chav tsev kub thiab tuaj yeem rov ua dua los ntawm cov khoom siv khib nyiab rov qab hauv kev tsim khoom, yog li hydrogen fluoride yuav tsis tshua nyob hauv cov slag.
C. Cov tshuaj fluorine nyob rau hauv fluorine gypsum muaj nyob rau hauv daim ntawv ntawm CaF2, uas yog insoluble nyob rau hauv dej, thiab nws cov ntsiab lus yog tsawg tshaj li 1 feem pua, yog li nws tsis ua phem rau ib puag ncig thiab tib neeg lub cev.
D. Fluorine gypsum nws tus kheej tsis muaj kev ua ub no, nws yog ib qho tsim nyog yuav tsum ntxiv cov txiv qaub, hloov pauv, activator thiab lwm yam khoom ntxiv los ua kom cov fluorine gypsum ua haujlwm zoo, yog li qhov zoo ntawm fluorine gypsum yog qhov ruaj khov heev.
E. Fluoro gypsum tsis muaj hluav taws xob thiab formaldehyde, yog li nws yog cov khoom siv hauv tsev ntsuab.
