Although the current buildings are mostly high-rise buildings,there are also older ones.The disadvantage of these houses is that they are very damp,which makes many people very irritable.Clothes placed inside the house will soon become moldy,and the walls will also be very damp.If some dehumidification and moisture-proof products such as lime and dehumidifiers are added,it will not have a significant relief.However,caustic soda has a good moisture-proof and dehumidification effect.
Because the chemical properties of caustic soda are commonly used as neutralizing agents in wastewater treatment,neutralization reactions occur.Wastewater often contains acid ions.At this time,it is necessary to add caustic soda into the wastewater to adjust the acid ions and neutralize the pH value,indicating that caustic soda is a chemical product with adjustable pH.Let's take a look at its regulation of pH value together:
1. As one of the important raw materials for water treatment, caustic soda will melt when placed in water, while releasing a large amount of OH ions, which can easily change the pH value. Simply put, it is a standard that can be used to determine the acidity or alkalinity of water;
2. In the process of water treatment, paying attention to changes in pH value can calculate its usage and predict more effective production of water treatment agents.
The above is the knowledge about the adjustable pH value of caustic soda introduced by the editor today. When water is neutral, it can not only adjust the pH value of sewage, neutralize its acidity, but also neutralize the pollutants in it. It is an alkaline substance commonly used in sewage treatment. In addition, its alkalinity is much weaker than that of soda ash and caustic soda, and it can be sprinkled on items that need to be moisture-proof without affecting the quality of the items. However, it is not recommended to use it in some large areas with water all year round, because if the ratio of water to caustic soda is not proportional, it will not only have no relevant effect, but also affect the surrounding environment.
