How much is "precipitated barium Sulfate sand"? What is the main material for making barium sulfate board? , drying, crushing and sieving to become the product. Precipitated barium sulfate has fine texture, high whiteness, and high acid, alkali, light, heat and chemical properties. The density of precipitated barium sulfate is 10, and the oil absorption is 10-15%. The refractive index is . The powder coating film has high gloss and good leveling, and is currently the most used type of powder coating. The principle is that in an acidic solution, Barium Chromate and sulfate form barium sulfate precipitation and release chromate ions. After the solution is neutralized, the excess barium Chromate and the generated barium sulfate are still in the precipitation state, and the precipitation is removed by filtration. Under alkaline conditions, the chromate ion is yellow, and the content of sulfate can be known by measuring its absorbance. I think everyone in the industry is very familiar with it. We remove barium sulfate precipitation when we don`t need it, but how can we remove it effectively? Of course, it would be a pity if the removed barium sulfate is disposed of as waste. Today I would like to tell you about the subsequent recycling of barium sulfate. How can barium continue to create new value. As a simple example, barium Chloride is often added in our process of refining brine. Raw materials or fillers for batteries, as fillers and reinforcements in rubber products, as fillers and weighting agents in polyvinyl chloride resins, and as surface coating agents for printing paper and coated paper. Barium sulfate is an unregulated chemical, and it is not dangerous, but according to the chemical properties of natural barium sulfate, it is known to be corrosive to a certain extent. On the skin, first aid measures should be taken immediately. How should natural barium sulfate come into contact with the skin? First of all, if there is no exposed skin, be sure to take off the clothes that have been spilled on the skin. Then rinse the spilled area with running water for at least 15 minutes. If it is very serious, it is best to send it to the hospital for medical treatment. If you accidentally inhale natural barium sulfate, you must leave the scene as soon as possible, and then go to a place with fresh air. If you feel breathing difficulties, give oxygen, and then go to the hospital for medical treatment. In case of accidental ingestion, induce vomiting with warm water immediately, and then send it to the hospital for medical treatment. If you have the above situation, you must not panic, calm yourself down, carry out corresponding emergency treatment and then send it to the hospital for treatment.
