The function of the corrosive safety storage cabinet

Corrosive safety storage cabinet is widely used in university laboratories, scientific research institutes and other places to safely and effectively store various weakly corrosive liquids, such as acetic acid, formic acid, acrylic acid, etc. If these liquids are not properly stored, they may cause harm to personnel or pollute the surrounding environment.

In laboratories, factories or other environments involving the use of chemicals, safety is always the primary consideration. Especially when it comes to corrosive chemicals, the correct storage and handling methods are not only related to the life of the equipment, but also directly related to the health and safety of personnel.

Corrosive substances refer to solids or liquids that can burn human tissue and damage metals and other objects. They are solids or liquids that cause visible necrosis within 4 hours of contact with the skin, or solids or liquids that have an annual uniform corrosion rate of more than 6.25 mm on the surface of No. 20 steel at a temperature of 55°C.

Corrosive substances are divided into three categories according to their chemical properties: acidic corrosives, alkaline corrosives and other corrosives.

1. Acidic corrosives: Acidic corrosives are more dangerous. They can corrode animal skin and metal. Strong acids can cause immediate skin necrosis.

2. Alkaline corrosives: Alkaline corrosives are more dangerous. Strong alkalis are prone to saponification, so they are easy to corrode the skin and can quickly cause visible necrosis of animal skin. Common corrosives in this category include sodium hydroxide, sodium sulfide, sodium ethanol, diethanolamine, dicyclohexylamine, hydrazine hydrate, etc.

3. Other corrosives: such as sodium phenol, chromium fluoride, sodium hypochlorite solution, formaldehyde solution, etc.

It is particularly important to store these chemicals in a scientific and standardized manner to prevent accidents. corrosive liquid safety storage cabinet came into being. It focuses on providing safe and efficient weakly corrosive liquid storage solutions to ensure the safety and clean environment of laboratories, chemical and medical sites.

What are the precautions for using corrosive safety storage cabinet?

1. Storage environment: Make sure the storage cabinet is placed in a dry, ventilated, light-proof environment, and keep the area around the cabinet clean and free of debris.

2. Isolation storage: Weakly corrosive liquids should be stored separately from other chemicals, especially oxidants and alkalis, to avoid possible chemical reactions.

3. Avoid direct sunlight: The storage cabinet should not be directly exposed to sunlight to avoid accelerated corrosion of the liquid due to high temperature or other hazards.

4. Static electricity protection: The storage cabinet should be equipped with an anti-static device to conduct static electricity to the ground to reduce the risk of fire caused by static electricity sparks.

5. Keep away from fire and heat sources: The storage cabinet should be away from fire, power and all heat sources to prevent the safety of the liquid from being affected by temperature changes.
