Ua nag losBarium sulfate(BaSO4), EINECS No. 231-784-4, yog ib qho kev nrhiav tom qab uas paub txog nws qhov tshwj xeeb purity, nrog tsawg kawg yog 98% BaSO4. Cov tshuaj ntau yam no yog siv thoob plaws ntau yam kev lag luam nrog rau cov xim, coatings thiab txawm tias roj teeb raug tsim. Nws cov khoom tshwj xeeb ua rau nws muaj qhov tseem ceeb hauv ntau daim ntawv thov, ua kom cov txiaj ntsig zoo.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm precipitated barium sulfate yog nws lub peev xwm los ua rau ntawm qhov loj. Cov neeg tsim khoom tau txhim kho cov txheej txheem kom ntseeg tau tias xa khoom sai yam tsis muaj kev cuam tshuam zoo. Qhov kev ua tau zoo no yog qhov tseem ceeb rau kev lag luam uas tso siab rau cov khoom siv hauv lub sijhawm kom tau raws li cov kev xav tau ntau lawm. Txawm hais tias nws yog ib qhov loj-scale txheej txheej los yog daim ntawv thov roj teeb tshwj xeeb, cov khoom siv zoo ntawm barium sulfate yog qhov hloov pauv kev ua si.
Barium sulfate yog ib qho tseem ceeb pigment thiab muab tub lim hauv kev lag luam xim thiab coatings. Nrog rau cov mis molecular ntawm BaSO4, nws txhim khu lub opacity thiab durability ntawm cov xim, muab ib tug zoo nkauj thiab ntev-ntev du nto. Tsis tas li ntawd, nws cov tshuaj ruaj khov ua kom ntseeg tau tias nws yuav tsis cuam tshuam nrog lwm cov khoom xyaw, ua rau nws muaj kev ntseeg siab rau cov qauv tsim.
Tsis tas li ntawd, kev siv cov barium sulfate hauv cov roj teeb tsim tau qhia txog nws txoj kev siv ntau yam. Raws li cov tshuaj sulfate, nws pab txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm cov roj teeb, ua rau nws yog ib feem tseem ceeb ntawm cov kev daws teeb meem niaj hnub no.
Nyob rau hauv xaus, precipitated barium sulfate yog ntau tshaj li ib tug compound, nws yog lub hauv paus ntawm ntau yam industries. Nrog nws cov purity siab, muaj peev xwm ntau lawm thiab ntau yam kev siv, BaSO4 tseem ua lub luag haujlwm tseem ceeb hauv kev txhim kho thev naus laus zis thiab txhim kho cov khoom zoo. Raws li kev lag luam loj hlob, qhov kev thov rau cov khoom siv zoo barium sulfate yuav tsis muaj kev vam meej, ua kom nws txoj haujlwm nyob hauv kev ua lag luam.
