Qhov txawv ntawm quartz xuab zeb thiab silica li cas?

Silica tuaj yeem raug xa tawm, tab sis kev xa tawm ntawm quartz xuab zeb yog txwv tsis pub, yog li kuv xav paub meej, kev lis kev cai txawv li cas? Cov ntsiab lus tshwj xeeb, cov ntsiab lus duab, xws li muaj pes tsawg leeg, daim ntawv, kev siv tshuab, thiab lwm yam.

Quartz xuab zeb yog ib hom quartz hais los ntawm crushing quartz pob zeb. Quartz pob zeb yog ib yam khoom uas tsis yog xim hlau. Nws yog ib qho nyuaj, hnav-tiv taus thiab tshuaj lom neeg ruaj khov silicate ntxhia. Nws cov ntxhia tseem ceeb yog SiO2, quartz xuab zeb Cov xim yog milky dawb, los yog tsis muaj xim thiab translucent, nrog ib tug Mohs hardness ntawm 7. Quartz xuab zeb yog ib qho tseem ceeb muaj ntxhia raw khoom, uas tsis yog-tshuaj lom cov khoom, lug siv nyob rau hauv iav, casting, ceramics thiab refractory cov ntaub ntawv, smelting ferrosilicon, metallurgical flux, Metallurgy, kev tsim kho, tshuaj, yas, roj hmab, abrasives, lim cov ntaub ntawv thiab lwm yam lag luam.

Silica xuab zeb, tseem hu ua silica lossis quartz xuab zeb. Nws yog raws li quartz raws li lub ntsiab ntxhia tivthaiv, thiab particle loj yog

Lub refractory hais txog 0.020mm-3.350mm tau muab faib ua silica xuab zeb, dej-ntxuav xuab zeb, txhuam xuab zeb, thiab xaiv (flotation) xuab zeb raws li kev sib txawv ntawm cov mining thiab kev ua haujlwm. Silica xuab zeb yog ib qho nyuaj, hnav-tiv taus, tshuaj lom neeg ruaj khov silicate ntxhia, thiab nws cov ntxhia tseem ceeb yog SiO2.

, Cov xim ntawm silica xuab zeb yog milky dawb los yog tsis muaj xim thiab translucent.

Cov khoom tseem ceeb ntawm quartz xuab zeb thiab silica xuab zeb yog sio2, uas txawv raws li cov ntsiab lus ntawm sio2. Cov uas muaj sio2 cov ntsiab lus siab dua 98.5% hu ua quartz xuab zeb, thiab cov uas muaj sio2 cov ntsiab lus qis dua 98.5% hu ua silica xuab zeb.

Quartz xuab zeb muaj qhov nyuaj siab, txog 7, thiab hardness ntawm silica xuab zeb yog 0.5 qib qis dua li ntawm quartz xuab zeb. Cov xim ntawm quartz xuab zeb yog siv lead ua ntshiab, thiab cov xim ntawm silica xuab zeb yog dawb huv, tab sis nws tsis ci thiab tsis muaj lub ntsej muag ntshiab.
