Barium sulfate, tseem hu ua precipitated barium sulfate, yog ib qho khoom siv dav siv. Nws cov mis molecular yog BaSO4 thiab nws qhov hnyav molecular yog 233.39, ua rau nws muaj txiaj ntsig zoo hauv ntau yam lag luam. Khaws nyob rau hauv qhov kub thiab txias-pov thawj, lub sijhawm siv tau tuaj yeem ncav cuag 2 xyoos, ua kom nws lub neej ua haujlwm thiab muaj.

Ib qho tseem ceeb ntawm kev siv barium sulfate yog los txiav txim siab cov ntsiab lus nitrogen ntawm cov qoob loo qhuav siv cov barium sulfate thiab nitric acid test hmoov txoj kev. Nws kuj yog siv los ntsuas qhov tshem tawm ntawm nitrogen los ntawm av. Tsis tas li ntawd, nws yog siv los tsim cov ntawv thaij duab thiab cov kaus ntxhw dag, nrog rau cov roj hmab fillers thiab tooj liab smelting fluxes.

Tsis tas li ntawd, barium sulfate kuj tseem siv rau hauv kev tsim cov automotive xim, xws li hluav taws xob primers, xim primers, topcoats thiab industrial xim, xws li xim hlau phaj xim, zoo tib yam xim qhuav, hmoov txheej, thiab lwm yam. Nws siv txuas mus rau architectural txheej, wood coatings, printing Inks, thermoplastics, thermosets, elastomer glues thiab sealants. Qhov versatility no ua rau nws yog ib qho tseem ceeb hauv ntau yam khoom thiab cov ntaub ntawv.

Cov khoom ntawm no compound ua rau nws zoo tagnrho rau ntau yam kev siv. Nws inertness, siab ceev thiab xim dawb pab rau nws cov hauj lwm zoo nyob rau hauv txawv industries. Ultrafine barium sulfate yog tshwj xeeb tshaj yog muaj nqis nyob rau hauv tsheb thiab industrial coatings, muab durability thiab high-zoo finishes.

Hauv cov ntsiab lus, kev siv ntau ntawm precipitated barium sulfate ua rau nws yog ib qho tseem ceeb ntawm ntau yam khoom thiab cov txheej txheem. Nws cov kev siv ntau yam, los ntawm kev sim ua liaj ua teb mus rau tsheb thiab cov txheej txheem kev lag luam, qhia txog nws qhov tseem ceeb hauv kev tsim khoom niaj hnub thiab kev coj ua. Raws li thev naus laus zis thiab kev tsim kho tshiab txuas ntxiv mus, kev thov rau barium sulfate yuav loj hlob, ntxiv dag zog rau nws txoj haujlwm ua cov khoom tseem ceeb thoob plaws hauv kev lag luam.
