Anhy Drous Sulfateoflime

1.Product presentation

      Fluoride gypsum yog cov khoom siv los ntawm hydrofluoric acid ntau lawm, feem ntau hu ua cov khoom pov tseg. Nws tau pib muab pov rau hauv qhov chaw cia khoom raws li khib nyiab slag, uas tsis tsuas yog cuam tshuam rau ib puag ncig tab sis kuj tseem cuam tshuam cov peev txheej. Tom qab kev txhim kho txuas ntxiv ntawm cov neeg ua haujlwm tshawb fawb thiab thev naus laus zis, kev siv dav dav ntawm cov peev txheej, hloov cov khoom pov tseg rau hauv cov khoom muaj nqis, tau siv ntau yam. Tshwj xeeb tshaj yog nyob rau xyoo tas los no, nrog rau kev ua haujlwm nyuaj ntawm cov kws tshawb fawb thiab cov neeg ua haujlwm, kev txhim kho thiab kev siv cov khoom siv fluoropgypsum tau ua tiav tshiab; Nws kuj daws teeb meem ib puag ncig zoo.

2. Cov khoom ntawm fluoropgypsum

Raws li ib qho tseem ceeb ntawm cov khoom siv raw khoom thiab cov khoom lag luam, gypsum yog dav siv nyob rau hauv ntau yam ntawm lub teb chaws kev lag luam xws li: kev tsim kho, kev ua liaj ua teb, tshuaj, aquaculture, kev lag luam, thiab lwm yam. Nws lub ntsiab tivthaiv yog CaSO: 2HzO. Muaj ob hom gypsum: ntuj gypsum thiab dag gypsum. Fluorine gypsum yog ib hom kev dag gypsum. Fluoropagsum yog tsim los ntawm calcium sulfate raws li cov khoom siv pov tseg tom qab cov tshuaj fluorite thiab sulfuric acid los tsim hydrofluoric acid. Thaum pib ntawm kev tsim khoom, cov khib nyiab pov tseg muaj me me ntawm sulfuric acid, uas yog neutralized los ntawm txiv qaub mis los yog av nplaum ore slurry, lim thiab qhuav kom tau fluoropyrite gypsum. Nws muaj nyob rau hauv daim ntawv ntawm CaSO plus 2H2O thiab CaSO4. Nws cov tshuaj muaj pes tsawg leeg yog qhia hauv Table 1 ".

3.Environmental tiv thaiv vaj tse

        Nyob rau hauv 1995, Hunan Building Materials Research and Design Institute tau ua qhov kev ntsuam xyuas muaj pes tsawg leeg ntawm fluoropgypsum ntawm Xiangaluminum. Cov txiaj ntsig tau pom tias tom qab qhov nruab nrab ntawm fluoropgypsum, cov ntsiab lus ntawm calcium sulfate feem ntau yog ntau dua 75 feem pua, thiab cov ntsiab lus ntawm neutralized fluoropgypsum thiab calcium sulfate tawm ntawm cov txheej txheem qhuav aluminium fluoride yog 95 feem pua. On, ib yam li ntuj gypsum. Ntawm qhov teeb meem ntawm kev tiv thaiv ib puag ncig ntawm fluoropgypsum, Tuam Tshoj lub koom haum ntawm Cov Khoom Siv Hauv Tsev rau fluoropgypsum cov haujlwm tshwj xeeb ntawm cov khoom siv hluav taws xob txiav txim siab pom tau tias fluoropgypsum radioactivity theem qis dua li cov txheej txheem hauv tebchaws! Raws li rau cov ntsiab lus HF, cov khoom yog ruaj khov ntawm 180 ~ -230'C thaum fluoropgypsum tsim, thaum cov hydrogen fluoride yog volatile heev nyob rau hauv chav tsev kub thiab yog zoo tu qab tso los ntawm cov khib nyiab roj rov qab ntaus ntawv nyob rau hauv cov khoom, yog li yuav luag. cov hydrogen fluoride yuav tsis nyob hauv lub slag ntawm qhov kub no. Fluoropgypsum muaj ib qho me me ntawm CaF2 (2.5 ~ 6.5 feem pua), tab sis nws yuav luag insoluble hauv dej thiab yuav tsis ua mob rau ib puag ncig thiab tib neeg lub cev.
