Barium sulfate industry USES

barite is a kind of very important non-metal mineral raw materials, has a wide range of industrial applications. The following is a function of containing barium carbonate barite:

1, drilling mud weighting agent

in some oil and gas well drilling, the general use of drilling mud, clay proportion of 2. Five or so, the proportion of water is 1, so the mud weight is low, sometimes the mud weight can't with underground oil and gas pressure balance, would cause blowout accident. Under the condition of the underground pressure is higher, you need to increase the mud weight, added to the mud barite powder is an effective measure to increase the mud weight. For drilling mud barite general fineness to achieve more than 325 mesh, such as inadequate barite fineness is prone to precipitation. Drilling mud barite requires specific gravity greater than 4. 2, BaSO4 content not less than 95%, less than 1% soluble salts.

2, lithopone pigment

lithopone is a commonly used high quality white pigments, can be used as paint, paint raw materials. Heat the barium sulfate, the use of reducing agent can be reverted to barium sulfide ( BaS) And then with zinc sulfate ( ZnSO4) Reaction of barium sulfate and the mixture of zinc sulfide ( BaSO4 accounted for 70%, ZnS 30%) administered Is the lithopone pigment. Barite requirements of producing lithopone BaSO4 content is greater than 95%, at the same time should contain no visible color clutter.

3, all kinds of barium salt barium compounds

on barite as raw material to produce barium oxide, barium carbonate, barium chloride, barium nitrate, precipitated barium sulfate, barium hydroxide and other chemical raw materials.

4, packing industrial barite

in the paint industry, barite powder filler can increase the film thickness, strength and durability. Lithopone pigments are used in the manufacture of white paint, using indoors than white lead, magnesium, white has more advantages.

5, cement mineralizer used in industry.

above is appropriate xin chemical industry is introduced on the power of barium carbonate, more details, welcome to consult appropriate xin chemical industry.
