Taw qhia

1. Barium sulfate muaj qhov sib txuam zoo rau hauv txheej txheej. Siv cov khoom no thiab titanium dioxide hauv ib qho kev faib ua feem ntawm tib lub sijhawm tuaj yeem ua kom titanium dioxide zoo dua hauv nws lub zog zais thiab txo cov nqi ntawm titanium dioxide, tshwj xeeb tshaj yog tsim nyog rau tsheb xim; qib high-qib xim tha xim sab nrauv ntawm phab ntsa yog siv. Nyob rau tib lub sijhawm, muaj qhov tshwj xeeb txhim kho nyob rau hauv kev ua los tiv thaiv chalking.

2. Barium sulfate hmoov txheej txheej tuaj yeem txhim kho qib thiab khaws cia ntawm cov hmoov txheej thiab muaj qhov sib txuam tau zoo nrog txhua cov xim, tuaj yeem txhim kho cov hmoov txheej kom ua tiav qhov zoo tshaj plaws zaj duab xis tuab hauv cov txheej txheem tha xim, thiab nce cov txheej tuab. Hmoov tus nqi, txo cov nqi ntawm cov hmoov txheej, yog qhov yuav tsum xaiv cov khoom lag luam rau qib qib hmoov ua kom nruj.

Barium sulfate txheej khoom:

Crystal tsis muaj orthorhombic siv lead ua los yog hmoov dawb amorphous.

Qhov ntsuas ntawm txheeb ze yog 4.50 (15 ° C). Lub ntsiab lus melting yog 1580 ° C.

Yuav luag insoluble hauv dej, ethanol thiab acid. Yaj nyob rau hauv kub concentrated sulfuric acid, nws yooj yim rau agglomerate thaum qhuav.

Cov pa roj carbon yuav raug txo kom tsawg li barium sulfide ntawm 600 ° C.

Barium sulfate muaj qhov siab ntawm cov ntxhiab thiab zoo npog cov khoom. Nws yog dav siv hauv cov hmoov txheej, kho xim dej hiav txwv, tshuaj pleev xim rau sab saum toj, pleev xim rau sab saum toj, pleev xim rau tsheb, xim pleev xim rau sab nrauv, sab hauv thiab sab nrauv phab ntsa sab nrauv kev kos duab txheej, thiab xoo hluav taws xob tiv thaiv cov chaw. Nws tuaj yeem hloov qee feem ntawm titanium dioxide thiab dav siv hauv cov roj hmab log tsheb, insulating roj hmab, hose, roj hmab cov roj hmab txhaws thiab engineering plastics, coated ntawv luam ntawv inks.

Hauv cov hmoov txheej, barium sulfate tuaj yeem txhim kho qib thiab khaws cia ntawm cov hmoov txheej thiab muaj qhov ua kom sib xyaw tau zoo nrog txhua xim. Nws tuaj yeem txhim kho cov hmoov txheej kom ua tiav zoo tshaj plaws cov yeeb yaj kiab tuab hauv cov txheej txheem txau, thiab nce hmoov ntxiv chaw nce, txo cov hmoov txheej txheej, uas yog cov khoom yuav tsum xaiv cov khoom lag luam qib hmoov.
