Barium sulfate has high purity, fine particle size, and uniform distribution. It has excellent properties such as chemical inertness, acid resistance, high temperature resistance, corrosion resistance, high whiteness, high refractive index, and easy dispersion. At the same time, it has a strong ray absorption function as a body pigment It is widely used in various advanced coatings, paints, inks and other industries. At the same time, it is also widely used as a filler in plastics, rubber, ceramics and friction materials. In addition, barium sulfate can reach 80% of its weight. It can be used in drainage pipes, speakers, and speakers to effectively isolate noise and noise. It can provide high gloss, good color, scratch resistance, and dimensional stability when used in housings of home appliances. Good and so on.
First, the application in paint
Barium sulfate is superior to most other filled powders. It has the characteristics of low cohesion, low light dispersion and fine particles. It is especially suitable for pigment topcoats, varnishes, spray paints, etc., and has chemical resistance and weather resistance. Its inertness, insolubility in water, acid, alkali and other organic intermediaries, excellent gloss and fineness of particles make the topcoat to be maintained during long-term exposure. Barium sulfate is recommended for topcoats to increase surface hardness and color stability.
Barium sulfate has high filling properties and can be applied to all coating series, such as all types of primers, thick coatings, etc. Its low specific surface area, particle size distribution and easy flowability make barium sulfate have low wear during processing Barium sulfate is recommended for the surface layer of automatic primer, and maintains good uniformity and smoothness even at high filling.
Application in latex paint
Barium sulfate is used in latex paints and is known as "acid-resistant" latex paints. Acid resistance even when exposed. The easy dispersibility, optical rotation and flowability of barium sulfate can increase its chemical properties.
Application in powder coatings
Barium sulfate used in powder coatings can improve its gloss, fluidity, filling properties and compatibility with various pigments.
Application in pigments
Barium sulfate is used as a gasket for titanium dioxide and pigments in plastics, which can reduce the amount of pigment added and save about 10% of the cost. Light reflection can maintain the complete color of the pigment.
V. Application in Insulating Materials
Titanium dioxide or pigment particles in coatings are usually not completely dispersed. The particles will agglomerate and reduce the scattering rate and hiding power, making these titanium dioxide aggregates a great waste. The average particle diameter of MICROBARI® submicron barium sulfate is about 1.3um, which is about twice that of titanium dioxide particles (average particle size is about 0.3μm). When MICROBARI® submicron barium sulfate is added, its mesoscopic microcrystalline particles can agglomerate Titanium dioxide particles are separated, each submicron barium sulfate particle has sufficient surface energy, and 4-10 titanium dioxide particles can be adsorbed around, effectively achieving space separation, so that the scattering rate of each titanium dioxide particle is large. .
Applying MICROBARI® submicron barium sulfate as a physical pigment to high-end products such as thin spray powder coatings, electrophoretic coatings, and high-gloss coatings can make your products more competitive in terms of technology and price.
Application in Silicone Rubber and Compound Rubber
Barium sulfate is used as a filler to increase the hardness and reduce the elasticity of silicone rubber.
Application in printing ink
Low abrasion, high gloss and color stability, low cohesion, and its easy flowability make barium sulfate suitable for high-quality printing inks.
Application in paper coatings
Used in the production of paper coatings, which can increase its gloss and fluidity when introduced, such as white transparent colored paper in art paper. The titanium dioxide part can be replaced with double barium sulfate without losing its gloss.
Application in elastomers and seals
Barium sulfate is especially suitable for elastomers, it does not contain any heavy metal pollution or rubber poisonous gas, so it is especially suitable for food and medicine, and can provide its stability and anti-aging properties.
Ten, the application in thermoplastics
Thermal conductivity and easy flow can reduce the injection molding time, and barium sulfate can be used as a nucleating agent to improve its strength and thermal stability.
Eleven, the application in adhesives
Good rheology, high filling and chemical resistance make barium sulfate suitable for adhesives, unsaturated polyesters and polyurethanes.
Application in the petroleum industry
Barite powder for drilling mud additives for 200 mesh and 325 mesh oil and gas fields.
Application in the chemical industry
The barium salt plant uses barite ore as raw material to produce zinc barium white, precipitated barium sulfate, and barium carbonate.
Fourteen, the application in the paint industry
It can be used as a filler for paints and coatings to replace the more expensive raw materials such as precipitated barium sulfate, Lide powder, titanium dioxide, and active silica. It is suitable for controlling the viscosity of the paint and making the product bright and stable.
15. Application in the plastic industry
It can be used as a filler for plastic ABS raw materials to make the product shiny and bright, and at the same time it can improve the product strength, stiffness and wear resistance.
16. Application in the rubber industry
Products under 500 mesh can be widely used as fillers in rubber products, reduce costs, improve product hardness, acid and alkali resistance, water resistance, etc., and have a good reinforcing effect on natural and synthetic rubber.
17. Application in Paper Industry
High fineness barite powder can be used as filler and coating filler for whiteboard and copperplate paper to improve whiteness and surface coverage. Product specifications: 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh, 1500 mesh, 2000 mesh, 2500 mesh, 3000 mesh, 4000 mesh, 5000 mesh, 6000 mesh.
18. Application in the cement industry
Guizhou barite, fluorite, gypsum and other composite mineralizers.
19. Application in the glass industry
Used as deoxidizer, clarifier, flux, can increase the optical stability, gloss and strength of glass.
Twenty, application in the construction industry
It is used as concrete aggregate and paving material, and it can be used to shield buried pipelines in swamp areas. It can be used in nuclear facilities, atomic energy plants, X-ray laboratories, etc. instead of lead plates to extend the life of pavement.
21. Application in other industries
Barite powder can also be used as a high-quality filler in ceramics and other industries.
