What should be paid attention to when using ultrafine precipitated barium sulfate in color paste
The precipitated barium sulfate in the industry is mainly generated by the reaction of barium sulfate and sulfuric acid, the reaction of barium chloride and sulfuric acid or sodium sulfate, and the reaction of barium sulfide and sodium sulfate. It acts as a filler in the fields of coating ink, plastic, rubber, glass, ceramics, etc. People are usually divided into coating-grade precipitated barium sulfate, plastic-grade precipitated barium sulfate, etc. according to different applications, which are more expensive than heavy barium. 3 Modified barium sulfate. It is further divided into modified barium sulfate and modified precipitated barium sulfate. Is the barite powder or precipitated barium sulfate through the relevant treatment to enhance its performance in a certain aspect, the application is similar to the precipitation, mainly depends on its related performance, which is further processed and refined, also known as modified ultra The price of fine barium sulfate or modified ultrafine precipitated barium sulfate is higher than that of precipitated barium sulfate.
⑴Appearance
Most of the dyes with high cost performance are easy to form agglomerates, which will weaken the dyeing power of the dyes. Regardless of whether it is a medical colorant, a solvent colorant, or a general-purpose colorant, the product will obviously improve its profitability.
⑵ relatively large luster
The colorants modified by ultrafine precipitated barium sulfate have extremely high gloss and rheological properties even at higher shades.
⑶ Reduce grinding time
The use of this product in the preparation of color paste can not only waste raw materials, but also prolong the grinding and evacuation time. The time required to reach the set color power is greatly extended.
⑷ reduce solvent content
Because of its extremely low specific nominal product, it is almost unresponsive to viscosity and can reduce VOC. It can increase the solid content of color paste and greatly reduce the amount of solvent.
The role of barium sulfate in the coating is as a solid filler, which increases the covering and whitening of the material. It is also a raw material for the manufacture of other barium salts. Although this index is not an index that directly affects the quality of barium sulfate, it is the determinant of the value of barium sulfate. Generally speaking, the finer the precipitated barium sulfate, the more difficult it is to process and the higher its value. grades, and their market prices vary greatly. Some paints in life are relatively common. After the construction of the protective wall of Shanghai medical barium sand supplier is completed, in order to prevent the volatilization of barium ions in the protective material, the wall must be calendered with cement mortar, that is, the construction is completed. HYJSFBM can carry out reasonable and optimized protection design and construction for radiation protection projects of various institutions and industrial and mining enterprises, provide products and services with good performance and quality, and undertake radiation protection and decoration projects for large computer rooms.
