Growth rate of ultrafine precipitated barium sulfate crystals


The growth rate of ultrafine precipitated barium sulfate crystals can be expressed by the first-order reaction equation. The growth rate decreases with the increase of PBTCA concentration, especially in the solution with low supersaturation, the growth rate of barium sulfate crystals decreases after adding PBTCA. 2 orders of magnitude. The inhibition of PBTCA on the growth of barium sulfate crystals is mainly due to its adsorption to special locations such as active growth points, and this adsorption is in line with the Langmuir isotherm adsorption characteristics. Due to the large difference in barium sulfate content, it will cause fluctuations in the quality and performance of friction materials. The emergence of ultrafine precipitated barium sulfate opens up a way to solve this technical problem. Because of its high specific gravity, ultrafine precipitated barium sulfate can be used to suppress blowouts in oil exploitation. After chemical extraction, ultrafine precipitated barium sulfate becomes ultrafine precipitated barium sulfate with a purity of 99.99%, which can be used as a fluorescent bleaching agent for paper, and can be used for barium meals in X-ray photography after processing and purification. Ultrafine precipitated barium sulfate is in the stomach A shadow that is opaque to rays is formed in the intestine, which is used to diagnose stomach problems. It can be seen that barium sulfate is harmless to the human body. Health hazards Pure barium sulfate is insoluble in water and non-toxic. Inhalation can cause tightness in the chest, chest pain, coughing, etc. Irritating to eyes. Long-term inhalation can cause barium pneumoconiosis. Environmental hazards are harmful to the environment and can cause pollution to the atmosphere.
