HC Chemical Network News: Barite ore has undergone deep processing to produce precipitated barium sulfate, high-light barium sulfate, ultra-fine barium sulfate, and nano-barium sulfate, which not only meet the needs of various industries, but also a big advantage for the plastics and rubber industries. As a high-quality and inexpensive filler, the extensiveness in practical applications is also gradually becoming popular. More than 50% of the barite production is used for oil and geological drilling. According to statistics, one ton of barite powder is consumed for every 30 meters of drilling, so the consumption is large. In the chemical industry, there is a fixed relationship between the production of various barium salts and the consumption of barite raw materials, and the consumption of barite is also large. The following is an analysis of the reasons for the increase in the growth rate of China's barium sulfate industry by Shandong Zhengcheng Mineral Materials Processing Factory:
China is the country with the most abundant and richest barite resources in the world. China's barite resources are mostly distributed in Guizhou, Yunnan, Shaanxi, Hubei, Hunan, Guangxi, Fujian and other places. As the consumption of mineral resources continues to increase, our environment is also facing new challenges. The demand for barite ore in various industries in China has been increasing, and the demand for barite ore in foreign markets has also undergone tremendous changes. In particular, the demand for the paint industry and the paint industry is relatively large, which directly drives the demand for barite. In 1996, world barite production was 4.415 million tons, an increase of 1.35% over 1995. At present, China has become the world's largest producer of barite and the world's largest exporter of barite. In the 1990s, the annual export volume of barite and its products was generally 1.5 to 2 million tons. In 1996, the export volume of barite and barium salt was 2.058 million tons, and the export value was 121 million US dollars, including 1.86 million tons of barite and 198,000 tons of antimony chemical products. The main exporting countries were the United States, the Netherlands, Japan and South Korea. The amount of barite imported from China is very small, and only a small amount of bismuth chemical products are imported. Other major producers include Mexico, the former Soviet Union, the United States, India, Turkey, and Morocco.
The in-depth analysis of the natural barium sulfate industry in 2016-2021 and the guidance report of the “13th Five-Year Plan†show that barium sulfate is also called barite, because it contains impurities such as CaCO3. It can be tested with dilute HCl or dilute HNO3. Natural BaSO4 can be used as a white pigment [ZnS.BaSO4]ZnSO4+BaS=ZnS.BaSO4] for the production of coatings or high-grade paper. It can be used as a raw material and filler for paints, inks, plastics and rubber. It is used in the chemical industry to produce BaCl2 and other bismuth-containing compounds. Precipitated barium sulphate is relatively pure. In medicine, it is mainly used as an internal medicine for examining the stomach and intestines.
Precipitated barium sulfate is one of the few stable salts in sulfate. It is mainly used as a weighting agent for oil and gas drilling mud. It is also an important mineral raw material for extracting metal lanthanum and preparing various cerium compounds. The most important bismuth compounds in the industry are barium carbonate, barium chloride, barium sulfate, barium nitrate, barium hydroxide, barium oxide, barium peroxide, barium chromate, barium manganate, barium chlorate, zinc barium white, polysulfide. Hey, etc.
Antimony compounds are widely used: as raw materials and fillers for rubber, plastics, pigments, coatings, paper, textiles, paints, inks, electrodes; as raw materials for sulfhydryl grease, oil refining, beet sugar, rayon; Used as insecticide, sterilizing agent, rodenticide, explosive, green fireworks, signal bomb, tracer, indicator of medical X-ray image, etc.; also used in glass, ceramics, leather, electronics, building materials, metallurgy and other departments.
Barium sulphate has high filling properties and can be applied to all types of coatings, such as primers, high-build coatings, etc. Its low specific surface area and particle size distribution and flowability make barium sulphate have low wear during processing. Sodium sulphate is recommended for use in automatic primer finishes and even topcoats even at high fills. Barium sulphate is superior to most other fillers, especially in chemical resistant coatings. Its inertness makes it insoluble in water, acid, alkali and organic mediation. Excellent gloss and fineness of the particles protect the topcoat from long-term exposure.
Barium sulfate is recommended for topcoats, which increase surface hardness and color stability. Applying barium sulphate (about 25%) to PP can make PP surface like ABS, without affecting PP's existing characteristics, providing high gloss and high hardness. Surface barium sulfate can reach 80% of its weight filling rate. Drain pipes, speakers, and sounds can effectively isolate noise and noise. Barium sulfate can be used for curtains to increase weight. It can be used in home appliances to provide high gloss, good color, scratch resistance, and good dimensional stability.
