1.Nws yog siv rau kev tsim cov hlau tungsten, tungstic acid thiab tungstate ntsev. Siv raws li mordant, pigment thiab catalyst. Nws kuj tseem siv tau los ua cov ntaub ntawv pov thawj hluav taws thiab cov tshuaj analytical reagent.
2.Cov khoom no yog siv los ua ntaub auxiliary tus neeg sawv cev, thiab cov khoom sib xyaw ua ke ntawm sodium tungstate, ammonium sulfate thiab ammonium phosphate yog siv rau kev tiv thaiv hluav taws thiab dej tsis zoo ntawm fiber ntau. Cov fiber ntau no tuaj yeem ua rau hluav taws kub nyhiab thiab rayon. Nws kuj tseem siv tau rau cov ntaub hnyav, tawv tanning, electroplating txheej tiv thaiv corrosion. Cov khoom no tuaj yeem siv los ua cosolvent kom txo tau qhov kub thiab txias thiab ntxiv cov xim.
25kg DRUM los yog kev xav tau ntawm cov neeg siv khoom. Khaws nws kom deb ntawm lub teeb ntawm qhov kub hauv qab 25 ℃.
