Barite is a barium sulfate mineral, and its main composition is barium sulfate (BaSO4).
As an important non-metallic raw material mineral, it has the advantages of insoluble in water, high density, good filling, non-toxic, and easy to absorb radiation.
It is widely used in chemical, petroleum, building materials, medicine and other industries.
Barite resources are my country's dominant minerals, but years of disorderly development and utilization have led to a gradual decrease in the competitiveness of barite resources in the international market.
my country consumes a huge amount of barite resources every year, of which 85%～90% of the total consumption is used as a weighting agent for oil and natural gas drilling; 5%～10% is used as a chemical raw material to produce barium compounds and used as a coagulant for synthetic rubber , Grease additives, catalysts, phosphors, etc.
; the final proportion of less than 5% is used for road construction, cement mineralizers, fillers, etc.
Increasing investment in technology research and development of high-end barite-based products and promoting industrial upgrading are one of the effective strategies for my country to develop and utilize barite resources in a reasonable and effective manner.
1.
Barite-based polymer material.
Barite is added to the polymer as a filler.
It is generally treated by an ultra-fine modification process.
The modified barite has good compatibility with the polymer material and can be uniformly dispersed.
In the matrix material, an inorganic/organic composite material is formed.
Barite has the characteristics of low cost, easy mining, wear resistance, corrosion resistance, light resistance, etc.
Therefore, adding it to rubber materials can reduce the shrinkage of rubber materials and improve the dimensional stability and rigidity of the materials.
, Thereby increasing the scope of application of rubber materials; on the other hand, adding to rubber materials as fillers can increase the added value of barite and reduce the cost of rubber materials.
In addition, barite has high density and stable chemical properties.
When barite is added to paint coatings, the acid and alkali resistance and weather resistance of the coating are significantly enhanced.
2.
Barium barium with extremely high neutron inelastic scattering cross section can shield neutrons, which directly promotes the application of barite cement-based materials in neutron shielding and protection projects.
The use of ultrafine barite powder to make high-density barium cement, barite mortar and barite concrete building materials can replace metal lead plates to shield nuclear reactors and build anti-radion and X-ray buildings for use in the atomic energy industry , Nuclear power plant and X-ray diffraction laboratory.
3.
Barite-based composite conductive material.
Barite is a natural white body pigment.
Barite is used as the core material and the doped modified SnO2 is used as the coating layer to make light-colored conductive pigments.
It can significantly increase the added value and use value of barite, and at the same time expand the scope of application of barite.
4.
Barite, the raw material for barium-containing compounds, is an important mineral resource for the production of barium.
Barium-containing ferrosilicon alloy has excellent physical and chemical properties.
In the process of steel production and casting, barium-containing ferrosilicon alloy formed by adding barium can significantly improve the quality of steel.
At present, bulk barite is mainly used as raw material and placed in a submerged arc furnace to mass-produce barium-containing ferrosilicon alloy by a continuous carbothermic reduction process.
5.
Heavy metal ion adsorption materials can dissolve toxic metal ions, which have caused serious pollution to the environment in recent years.
The removal of toxic metal ions is one of the effective means to improve environmental problems.
Studies have found that due to the structure of barite, hexavalent chromium ions interact with the surface of barite, and the barite grains grow epitaxially to form Ba (CrO4, SO4) solids, thereby achieving the absorption of chromium ions.
To achieve the purpose of purifying the environment.
6.
Titanium dioxide, a barite inorganic composite pigment, is a high-quality coating, which occupies an important position in modern coatings.
At the same time, titanium dioxide is also an important photocatalytic material.
It has been found that nanometer titanium dioxide can treat more than 80 toxic compounds.
Due to the increasing amount of titanium dioxide, it is imminent to find a substitute for it.
Barite has high whiteness and stable properties.
As a core material compounded with titanium dioxide, it can effectively solve the easy agglomeration characteristics of titanium dioxide and improve the photocatalytic properties of titanium dioxide.
At the same time, it can be used as a coating instead of titanium dioxide.
