Kev piav qhia ntawm cov khoom

Lanthanum sulfate hydrate muaj ntau yam khoom siv lub cev thiab tshuaj uas ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv. Vim nws cov dej solubility siab, lanthanum sulfate pom muaj kev siv dav hauv cov txheej txheem kho dej. Nws ua haujlwm ua cov coagulant thiab flocculant zoo, pab tshem tawm cov pa phem thiab cov khoom me me ntawm cov dej. Tsis tas li ntawd, lanthanum sulfate yog siv los ua cov tshuaj catalyst hauv ntau yam tshuaj lom neeg, suav nrog kev tsim cov tshuaj intermediates thiab cov organic compounds.

Tsis tas li ntawd xwb, lanthanum sulfate yog ib qho tseem ceeb hauv kev tsim cov phosphors rau kev siv teeb pom kev zoo. Nws muaj cov khoom ci ntsa iab zoo heev, ua rau nws tsim nyog rau cov teeb fluorescent, cathode ray tubes (CRT), thiab lwm yam thev naus laus zis tso saib.

Lub tuam txhab WONAIXI (WNX) yog ib lub chaw tsim khoom ntawm cov ntsev av tsawg thiab cog lus rau Kev Tshawb Fawb thiab Kev Txhim Kho ntawm thev naus laus zis. Peb lub tuam txhab lub hom phiaj yog tsim cov khoom zoo,wPeb tau tsim cov lanthanum sulfate rau ntau tshaj kaum xyoo nrog rau txhua xyoo muaj peev xwm tsim tau 2,000 tons, peb cov khoom lanthanum sulfate raug xa tawm mus rau ntau lub tebchaws thiab thaj chaw thiab lanthanum sulfate tuaj yeem hloov kho los ntawm ntau yam kev siv.
