1. Drilling mud weighting agent When drilling some oil and gas wells, the drilling mud and clay generally used have a specific gravity of about 2.5, and the specific gravity of water is 1. Therefore, the mud weight is low, and sometimes the mud weight cannot be balanced with the underground oil and gas pressure. It caused a blowout accident. In the case of high underground pressure, it is necessary to increase the specific gravity of the mud. Adding barite powder to the mud is an effective measure to increase the specific gravity of the mud. The barite used for drilling mud generally has a fineness of more than 325 mesh. If the fineness of the barite is insufficient, precipitation is likely to occur. The barite for drilling mud requires a specific gravity of more than 4.2, the BaSO4 content is not less than 95%, and the soluble salt is less than 1%.
2, zinc bismuth white pigment Zinc bismuth white is a commonly used high-quality white pigment, can be used as a raw material for paints and paints. The mixture of barium sulfate and barium sulfide (BaS) can be reduced by using a reducing agent, and then a mixture of barium sulfate and zinc sulfide obtained by reacting with zinc sulfate (ZnSO4) (70% of BaSO4 and 30% of ZnS) is zinc barium. White pigment. The preparation of zinc-white barite requires a BaSO4 content of greater than 95% and should not contain visible colored impurities.
3. Various antimony salt compounds The barium can be used as raw materials to produce chemical raw materials such as barium oxide, barium carbonate, barium chloride, barium nitrate, precipitated barium sulfate and barium hydroxide.
Chemically pure barium sulfate is the standard for measuring whiteness; barium carbonate is an important raw material for optical glass, which introduces BaO into glass, thereby increasing the refractive index of glass and improving other optical properties; Barium chloride is an agricultural pesticide; barium nitrate is used in the fireworks and glass industries; barium permanganate is a green pigment.
4. Barite for filler industry In the paint industry, barite powder filler can increase the thickness, strength and durability of paint film. Zinc antimony pigments are also used in the manufacture of white paints, which have more advantages than lead white and magnesium white. Barite used in the paint industry requires sufficient fineness and high whiteness. The paper industry, rubber and plastics industries also use barite as a filler, which improves the hardness, wear resistance and aging resistance of rubber and plastics. Barite fillers for rubber and papermaking generally require BaSO4 to be greater than 98% and CaO to be less than 0.36%. Magnesium oxide, lead and other components are not allowed.
(1) Paint and high-paste coating Barite powder has high filling properties and can be applied to all coating series, such as primer, thick coating, etc., with low specific surface area and particle size fraction and flowability. The barite powder has low wear during processing, and barium sulfate is recommended for the surface layer of the automatic primer, and even maintains good uniformity and smoothness even in high filling.
(2) Topcoat barite powder is superior to most other fillers, especially in chemical resistant coatings. It is inert, insoluble in water, acid, alkali and organic intermediary. Excellent gloss and fineness of the particles allow the topcoat to be protected from prolonged exposure. Barium sulfate is recommended for topcoats which increase surface hardness and color stability.
(3) Latex paint Due to the weight, barite powder can only be used in latex paint, mainly used for high gloss and silk paint, and is known as "acid resistant" latex paint. It has acid resistance even when exposed. The easy dispersibility of barite powder, optical rotation and easy retention can increase its chemical properties. Barium sulfate can be used in high gloss paints and latex paints.
(4) Low abrasion of printing ink, high gloss and color stability, low cohesiveness, combined with its fluidity, make barite powder suitable for high-quality printing ink, barium sulfate is recommended for high-rotation ink.
(5) Wood products and paint barite powder have the characteristics of low cohesion, low light dispersion and fine particles, and are especially suitable for pigment topcoats, varnishes, spray paints, and the like. It is studied that barium sulfate has chemical resistance and resistance. (6) Powder coating: used in powder coatings, barite powder can improve its gloss, fluidity, filling and compatibility with various pigments.
(7) Adhesive: good rheology, high filling and chemical resistance, making barium sulfate suitable for adhesives, unsaturated polyesters and polyurethanes.
Elastomer, sealing body: It is especially suitable for elastomers. It does not contain any heavy metal pollution or rubber gas, so it is especially suitable for food and medicine, and can provide its stability and anti-aging properties.
Thermoset: Barite powder is inert, color stable, combined with other pigments for better gloss, mechanical properties and low abrasion.
(8) Thermoplastics: Thermal conductivity and flowability can reduce the injection molding time, and barium sulfate can be used as a nucleating agent to improve its strength and thermal stability.
Pigment: Light reflection can maintain the complete color of the pigment. (9) Paper coating: It can increase its gloss and fluidity, such as white transparent paper in art paper. The titanium dioxide portion can be replaced with double-prepared barium sulfate without losing its gloss.
5. Mineralizers used in cement industry In the cement production, the combination of barite and fluorite composite mineralizer has obvious effects on promoting C3S formation and activation of C3S. The quality of clinker is improved, and the early strength of cement can be improved. 20 to 25%, the late strength is increased by about 10%, and the clinker firing temperature is lowered from 1450 ° C to 1300 ± 50 ° C. When the amount of barite is 0.8 to 1.5%, the effect is the best. In the production of white cement, after the barite and fluorite composite mineralizer, the firing temperature is lowered from 1500 °C to 1400 °C, the free CaO content is low, and the strength and whiteness are improved. Adding an appropriate amount of barite to the cement raw meal using coal gangue as raw material can greatly improve the cement strength of the clinker saturation ratio, especially the early strength, which is the comprehensive utilization of coal gangue for production. Low calcium, energy saving, early strength and high strength cement provide a beneficial way.
6. Anti-radiation cement, mortar and concrete use barite to absorb X-rays. Barite is used as barium cement, barite mortar and barite concrete to replace metal lead plate shielded nuclear reactor and construction research. Hospital anti-X-ray buildings.
Tantalum cement is made of barite and clay as the main raw material. After sintering, the clinker composed of dimuth silicate as the main mineral is added, and the appropriate amount of gypsum is added to grind together. The specific gravity is higher than that of ordinary Portland cement, which can reach 4.7-5.2. The strength number is 325-425. Due to the large specific gravity of the concrete, it can be combined with heavy aggregates (such as barite) to form a uniform and dense anti-X-ray concrete.
Barite mortar is a kind of mortar with large bulk density and barrier effect on X-rays. It is generally required to use Portland cement with low hydration heat. Commonly used cement: barite powder: barite sand: coarse sand The ratio is 1:0.25:2.5:1. Barite concrete is a kind of concrete with large bulk density and shielding ability for X-rays. Cementitious materials generally use Portland cement with low hydration heat or special cement such as high alumina cement, strontium cement and strontium cement. Portland cement is the most widely used. The commonly used cement: barite crushed stone: barite sand: water mixture ratio is 1:4.54:3.4:0.5; 1:5.44:4.46:0.6; 1:5:3.8:0.2 three.
For anti-radiation mortar and concrete barite, the content of BaSO4 should not be less than 80%, and the impurities such as gypsum, pyrite, sulfide and sulfate should not exceed 7%.
7. Road construction Rubber and asphalt mixture containing about 10% barite have been successfully used in parking lots and are a durable paving material. At present, the tires of heavy road construction equipment have been partially filled with barite to increase the weight, which is beneficial to the å¡«8, other barite and oil materials in the filling area, and then applied to the cloth base to make tarpaulin; the barite powder is used for refining. Kerosene; digestive tract contrast agent in the pharmaceutical industry; pesticides, leather, fireworks, etc. In addition, barite is also used as an extraction metal crucible for use as a getter and binder for televisions and other vacuum tubes. It is alloyed with other metals (aluminum, magnesium, lead, calcium) for bearing manufacturing.
