Read： 424 Time：18months ago Source：Transform the World with Simplicity

Potassium hydroxide is an important chemical material with a wide range of applications and functions. It is a strong alkaline substance composed of potassium ions and hydroxide ions. It is a white solid at room temperature and soluble in water. Below we will introduce the common application areas of potassium hydroxide:

1. production of fertilizer: potassium hydroxide is widely used in fertilizer production, high purity potassium hydroxide can improve the nitrogen, phosphorus and potassium content of fertilizer, and enhance the effect of fertilizer.

2. Manufacturing glass: The glass manufacturing process needs to use potassium hydroxide to adjust the hardness and transparency of the glass, and it can also be used to remove contaminants and purify the glass surface.

3. Making soap: In the process of making soap, potassium hydroxide can be used as a catalyst to promote the reaction of fatty acids and lye to form soap.

4. catalytic reaction: potassium hydroxide plays an important role in the chemical catalytic reaction, which can greatly improve the efficiency of the catalyst.

5. Plating: Potassium hydroxide can be used as an electrolyte for electroplating and is used for electroplating of metal surfaces, thereby improving the properties and appearance of metal surfaces.

Although potassium hydroxide is widely used in the production workshop, the following skills need to be paid attention to in the specific use process:

1. Strong alkaline. In the process of operation to avoid direct contact with the skin and mucous membranes, especially for the higher concentration of potassium hydroxide.

2. Hydrolysis. In the use of the process to pay attention to the control of potassium hydroxide and water contact time and temperature, in order to prevent the generation of large amounts of heat and lithium hydroxide.

3. Reactions. Due to the strong alkalinity of potassium hydroxide, it will release a lot of heat when reacting with acids, and it is necessary to pay attention to prevent dangerous situations during the reaction.

4. Storage. Avoid contact with acids, calcium ions and other substances during storage to avoid unnecessary chemical reactions.

To sum up, potassium hydroxide is a very important and widely used chemical material, in the production workshop has its unique role. In the process of use, it is necessary to follow the principle of chemical safety, and pay attention to the mastery of skills and details to achieve better application results.
