Kev Piav Qhia & Nta

Piav Qhia: WNX siv cov thev naus laus zis tsim khoom tsis siv neeg thiab siv cov khoom siv raw zoo los tsim cov khoom zooLanthanum Sulfate Hydrare.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Lanthanum Sulfate Hydrare tsis muaj cov khoom tsis huv los ntawm cov khoom tsis tshua muaj (xws li hlau, calcium, sodium), thiab cov ntsiab lus tsis huv yog tsawg.

Kev yaj zoo:Lanthanum Sulfate Hydrare tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws: Kev tswj hwm cov khoom nruj hauv kev tsim khoomLanthanum Sulfate Hydrare

ua kom ruaj khov zoo rau kev lag luam loj.

Cov tshuaj catalyst hauv kev lag luam tshuaj lom neeg: Cov hydrated lanthanum sulfate yog ib qho tseem ceeb ntawm cov catalytic cracking (FCC) catalyst siv hauv kev lag luam petrochemical. Nws tuaj yeem txhim kho qhov ua tau zoo ntawm kev hloov cov roj av hnyav mus rau hauv roj av thiab diesel uas muaj octane siab. Nws kuj tseem tuaj yeem ua haujlwm ua catalyst lossis catalyst precursor rau qee cov tshuaj tiv thaiv organic synthesis.

Cov ntaub ntawv khaws cia tshuaj lom neeg kub: Vim nws cov yam ntxwv ntawm kev ua kom qhuav / dej rov qab tau, lanthanum sulfate hydrate yog cov khoom siv khaws cia tshuaj lom neeg kub zoo heev. Nws tuaj yeem ua rau muaj kev hloov pauv rov qab tau hauv qhov kub tsawg (kwv yees li 100°C txog 250°C), thiab siv rau kev rov qab thiab khaws cov cua sov pov tseg hauv kev lag luam. Nws muaj qhov ceev cia hluav taws xob siab thiab lub voj voog ruaj khov zoo heev.

Tshuaj Tshem Tawm Phosphorus Hauv Pas Dej: Vim nws cov khoom siv tshuaj lom neeg, lanthanum sulfate tuaj yeem tshem tawm cov phosphate ntawm cov dej los ntawm kev nag, uas yog qhov pab tau rau kev daws teeb meem ntawm cov dej hauv lub cev eutrophication.

Cov tshuaj lom neeg nruab nrab: Raws li qhov tseem ceeb ntawm lanthanum, cov hydrated lanthanum sulfate yog qhov tseem ceeb precursor rau synthesizing lwm cov lanthanum compounds, thiab yog siv los npaj ntau yam khoom siv xws li lanthanum oxide thiab lanthanum-based phosphors. Nws kuj yog siv ua reagent hauv kev tshawb fawb xws li spectroscopy tsom xam thiab kev txiav txim siab ntawm atomic qhov hnyav ntawm cov ntsiab lus.
