1. use
of hydrofluoric acid
hydrofluoric acid is a widely used chemicals, its main uses are as follows:

1. material manufacturing: hydrofluoric acid can be used to manufacture ceramics, silicon, transistors, batteries and other materials.

2. metal processing: hydrofluoric acid can be used to etch metal parts, manufacturing a variety of precision parts.

3. chemical reagents: hydrofluoric acid can be used to make other chemical reagents, such as calcium fluoride, aluminum fluoride and so on.

4. pyrotechnic chemicals: hydrofluoric acid can be used to make fireworks, pyrotechnic chemicals, etc.

2. the harm of hydrofluoric acid

1. corrosion: hydrofluoric acid on the skin and mucous membranes have a strong corrosive effect, once contact with the skin or into the respiratory system, will cause serious burns.

2. Neurotoxicity: The toxicity of hydrofluoric acid can cause great damage to the human nervous system.

3. Asphyxia: In the process of inhaling hydrofluoric acid, there will be a strong pungent smell, which will cause respiratory diseases and, in severe cases, suffocation.

4. Fire and explosion: Hydrofluoric acid is flammable and explosive, and improper storage or use can easily cause fire or explosion.

3. the correct use of hydrofluoric acid measures

in order to reduce the dangers of hydrofluoric acid, need to take the following measures:

1. improve safety awareness: any use of hydrofluoric acid personnel are required to accept strict safety training, familiar with the use of methods and emergency treatment methods.

2. Accurate use: The use of hydrofluoric acid needs to be calculated and proportioned to make the required liquid to avoid waste and pollution.

3. Protective measures: Suitable protective facilities should be installed near hydrofluoric acid, such as ventilation facilities, protective clothing, etc.

hydrofluoric acid is a commonly used chemical and has a wide range of applications in many fields. However, it must be noted that it is also very harmful. When using hydrofluoric acid, you must pay attention to safety measures and use it accurately to avoid endangering human health and safety.
