Cov xuab zeb quartz uas ntxuav nrog kua qaub

Cov txheej txheem pickling thiab pickling ntawm quartz xuab zeb

Thaum xaiv cov xuab zeb quartz huv thiab cov xuab zeb quartz huv siab, nws nyuaj rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem ib txwm muaj, tshwj xeeb tshaj yog rau cov hlau oxide zaj duab xis ntawm qhov chaw ntawm cov xuab zeb quartz thiab cov hlau tsis huv hauv cov kab nrib pleb. Txhawm rau txhim kho qhov zoo thiab cov txiaj ntsig ntawm cov xuab zeb quartz purification, ua ke nrog cov yam ntxwv ntawm cov xuab zeb quartz insoluble hauv acid thiab me ntsis soluble hauv KOH kua, txoj kev leaching acid tau dhau los ua ib txoj hauv kev tsim nyog los kho cov xuab zeb quartz.

Kev kho cov xuab zeb quartz pickling yog kho cov xuab zeb quartz nrog hydrochloric acid, sulfuric acid, oxalic acid lossis hydrofluoric acid kom yaj hlau.

Cov txheej txheem yooj yim ntawm quartz xuab zeb pickling

Kuv proportioning acid lotion

Cov xuab zeb yuav tsum tau ua los ntawm 7-9% oxalic acid, 1-3% hydrofluoric acid thiab 90% dej sib tov; Yuav tsum tau 2-3.5 tons dej, yog tias cov dej rov ua dua tshiab, ces tsuas yog xav tau 0.1 tons dej los ntxuav ib tons xuab zeb, hauv kev ntxuav xuab zeb, yuav ua rau feem ntau ntawm cov xuab zeb nce siab; Kev kho xuab zeb quartz pickling yog kho xuab zeb quartz nrog hydrochloric acid, sulfuric acid, oxalic acid lossis hydrofluoric acid kom yaj hlau.

Ⅱ Cov khoom sib xyaw ua ke

Cov kua pickling raug txhaj rau hauv lub tank pickling thiab ntxiv raws li qhov sib piv ntawm cov hydrochloric acid cov ntsiab lus li 5% ntawm qhov hnyav xuab zeb kom ntseeg tau tias cov xuab zeb quartz tau ntub rau hauv cov kua pickling thiab cov hydrochloric acid cov ntsiab lus yog li 5% ntawm qhov hnyav xuab zeb.

Ⅲ Cov xuab zeb quartz uas ntxuav nrog kua qaub
① Lub sijhawm rau cov xuab zeb quartz kom ntub cov kua pickling feem ntau yog 3-5 teev, qhov xav tau tshwj xeeb kom nce lossis txo lub sijhawm ntub raws li daim tawv nqaij daj ntawm cov xuab zeb quartz, lossis cov kua pickling thiab xuab zeb quartz tuaj yeem do rau ib lub sijhawm, ua raws li kev siv cov khoom siv cua sov kom sov cov kua rau qee qhov kub, tuaj yeem txo lub sijhawm pickling.

② Kev siv oxalic acid thiab ntsuab alum ua tus neeg sawv cev txo qis kev kho mob pickling tuaj yeem txhim kho qhov solubility ntawm hlau, ua rau, dej, oxalic acid, ntsuab alum raws li qhov sib piv ntawm cov tshuaj ntawm qee qhov kub thiab txias, xuab zeb quartz thiab cov tshuaj raws li qhov sib piv ntawm kev sib tov, do, kho rau ob peb feeb, cov tshuaj raug lim tawm thiab kho tom qab rov qab.

③ Kev kho mob Hydrofluoric acid: Qhov cuam tshuam zoo thaum kev kho mob hydrofluoric acid siv ib leeg xwb, tab sis qhov concentration siab dua. Thaum sib koom nrog sodium dithionite, qhov concentration qis dua ntawm hydrofluoric acid tuaj yeem siv tau.

Ib qho kev sib xyaw ua ke ntawm hydrochloric acid thiab hydrofluoric acid kua tau sib xyaw rau hauv cov xuab zeb quartz slurry tib lub sijhawm raws li qhov sib piv; Nws kuj tseem tuaj yeem kho nrog hydrochloric acid kua ua ntej, ntxuav thiab tom qab ntawd kho nrog hydrofluoric acid, kho ntawm qhov kub siab rau 2-3 teev, thiab tom qab ntawd lim thiab ntxuav.

Lus Cim:

Yog tias hydrofluoric acid siv los ua kom cov xuab zeb quartz ntub dej, qhov kev ua haujlwm nyuaj dua. Ntxiv nrog rau kev yaj cov hlau hauv cov xov xwm acidic, HF kuj tseem tuaj yeem ua haujlwm nrog quartz nws tus kheej kom yaj SiO2 thiab lwm yam silicates ntawm qee qhov tuab ntawm qhov chaw.

Txawm li cas los xij, qhov no zoo dua rau kev ntxuav qhov chaw ntawm cov xuab zeb quartz thiab tshem tawm cov hlau thiab lwm yam kev ua qias tuaj, yog li hydrofluoric acid zoo rau kev rho tawm cov kua qaub ntawm quartz. Txawm li cas los xij, HF yog lom thiab corrosive heev, yog li cov kua qaub uas rho tawm cov dej khib nyiab xav tau kev kho mob tshwj xeeb.

Iv Acid rov qab thiab deacidification

Yaug cov xuab zeb quartz uas muaj kua qaub nrog dej 2-3 zaug, thiab tom qab ntawd neutralize nrog 0.05% -0.5% ntawm sodium hydroxide (caustic soda) alkaline kua, thiab lub sijhawm neutralization yog li 30-60 feeb, thiab xyuas kom meej tias tag nrho cov xuab zeb quartz raug neutralized nyob rau hauv qhov chaw. Thaum pH ncav cuag alkaline, koj tuaj yeem tso lye thiab yaug 1-2 zaug kom txog thaum pH yog nruab nrab.

Ⅴ Cov xuab zeb quartz qhuav

Cov xuab zeb quartz yuav tsum tau nchuav tawm ntawm dej tom qab rho tawm cov kua qaub, thiab tom qab ntawd cov xuab zeb quartz yuav tsum tau ziab hauv cov khoom siv ziab.

Ⅵ kev tshuaj ntsuam, kev xaiv xim thiab kev ntim khoom, thiab lwm yam.

Qhov saum toj no yog cov txheej txheem yooj yim ntawm cov xuab zeb quartz pickling thiab leaching kho cov txheej txheem, quartz xuab zeb ore muaj kev faib tawm dav hauv peb lub tebchaws, yog li muaj qhov sib txawv ntawm qhov xwm txheej ntawm quartz xuab zeb, hauv kev ntxuav ntawm quartz xuab zeb kuj xav tau cov teeb meem tshwj xeeb kev tshuaj xyuas tshwj xeeb, tsim cov txheej txheem ntxuav quartz xuab zeb tsim nyog.
