Märkäkemikaalit

Märkäkemikaalit, often translated as wet chemicals, refers to chemical substances that are in a liquid state under normal conditions or are handled in solution. This contrasts with dry chemicals, which are typically solids or gases. The term is commonly used in various fields, including chemistry laboratories, industrial processes, and fire suppression systems.

In laboratory settings, wet chemicals are the standard form for reagents, solvents, and indicators. They are easier to measure, mix, and dispense than solids, facilitating precise experimental procedures. Many chemical reactions are performed in aqueous solutions or with organic solvents, making the liquid form essential.

In industrial applications, wet chemicals are crucial for processes such as chemical synthesis, cleaning, and surface treatment. They can be transported, pumped, and mixed in large quantities, allowing for continuous or batch production. Examples include acids, bases, and various organic compounds used in manufacturing.

The term "wet chemical" is also prominent in the context of fire extinguishers. Wet chemical fire extinguishers are specifically designed for Class K fires, which involve cooking oils and fats in commercial kitchens. These extinguishers contain a liquid agent that cools the burning oil and creates a foam blanket, preventing reignition. This is distinct from dry chemical extinguishers, which use powders to suppress flames. The handling and storage of wet chemicals require appropriate safety measures to prevent spills, exposure, and reactions with incompatible substances.
