How to distinguish the grade and composition of radiation protection barium sulfate
The mineral barium sulfate is called barite. Bafeng series barium sulfate is white or gray-black amorphous powder. Stable in nature, insoluble in water, acid, alkali or organic solvent. The product has good chemical stability and weather resistance. As a filling material, it is suspended without precipitation and has good compatibility with other pigments. It is a good carrier for primers, topcoats, paints, automotive paints, latex paints, powder coatings, inks, ships, rubber, plastics, fine chemicals and other colors. Natural barium sulfate? Natural barium sulfate is barite ore, which is processed by beneficiation, ore washing, crushing and other processes. Barium sulfate has the advantages of strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high specific gravity, high whiteness, and can absorb harmful rays. It is a material with environmental protection functions. The performance characteristics of ultrafine barium sulfate.
Barium cement mortar is the abbreviation of barium sulfate cement mortar material for radiation protection mortar. It is also called barite protective material. It is a very good protective material for high-energy ray protection. It has the advantages of low doubling, convenient construction and long service life. The performance of absorbing X-rays, barite mortar is a kind of mortar with a large bulk density and a blocking effect on X-rays; the barite content of anti-ray mortar and concrete should not be less than 80%. Barite is used to make barium cement, barite mortar and barite concrete, which can be used to replace metal lead plates to shield nuclear reactors and build scientific research and hospital X-ray-proof buildings. After construction, it is better to paint the wall with barium sulfate powder as double protection against radiation. Professionally speaking, barium coating has the effect of radiation protection. Generally, it is mainly used in the radiology department.
Barium sulfate is made from barite as the main raw material, which is processed by beneficiation, washing and crushing. The hardness of barium sulfate is 3～(Mohs), the specific gravity is ～, and it has the flash point of large specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the creation of some high-performance barium sulfate products, the application field of barium sulfate is expanding for a long time. At present, barium sulfate has many functions and the industries with large demand are as follows: the application of barium sulfate in paint.
The anti-radiation barium sulfate has high quality and superior performance, can absorb X-ray and γ-ray, and endow the material with high density and surface finish. The original advanced production technology makes the particle size of the product particles strictly controlled within a certain range, and adopts advanced drying technology, so that the physical properties of radiation-proof barium sulfate are particularly superior, and it has good dispersion with other media during the application process. In the paint industry, barite powder filler can increase the thickness, strength and durability of the paint film. .
