Potassium hydroxide is strongly alkaline and corrosive. Easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide and potassium carbonate. Dissolve in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerol. When dissolved in water, alcohol or treated with acid, a large amount of heat is generated. Today, we will learn about the reasons for the high cost of solid potassium hydroxide.
1. Due to the need of coal baking in the production process of solid potassium hydroxide, and the rapid rise of coal price, the production cost is also high;
2. Now the price of oil is soaring, so the freight is also rising. When the goods are delivered to the buyer, the price is higher than usual;
3. As the price of liquid caustic soda increases gradually, the cost of making caustic soda also increases correspondingly, so the price of solid potassium hydroxide also increases.
The above is the reason why the cost of solid potassium hydroxide is high. In addition, potassium hydroxide is also called active flame retardant and sodium glue in industry. According to its structural characteristics, it can be found that oxygen ions are close packed with cubic face centers, and Al3 + is irregularly distributed in the octahedral and tetrahedral voids surrounded by oxygen ions. γ - type flame retardant is insoluble in water, but soluble in strong acid or alkali solution. When heated to 1200 ℃, it will be converted into α - type flame retardant.
