Dry Chemical Powder 

Dry Chemical Powder

Dry Chemical Powder is mono-ammonium phosphate-based powders that are commonly made for multipurpose use against Class A, B and C fires. These dry chemical powders come in 40% and 90% of ingredients and are used in extinguishers to put out fire by coating the fuel with a thin layer of dust and thus it separates the fuel from the oxygen in the air.

The powder tends to interrupt the chemical reaction of fire and that is why all extinguishers with dry chemical powder are extremely effective at putting out fire instantly. Dry chemical powder contains an extinguishing agent that spreads easily and melts over flames. When the powder covers a fire, it blocks heat and oxygen and thus causes fire to die down immediately. It also works as a great heat shield.

Dry chemical powder is a chemical agent that is suitably used on either distinguishes fires. the powder makes up the chemical agents that are sodium bicarbonate based and blue and white in colour, while purple dry chemical agent is based on potassium bicarbonate. Dry chemical means a powder that is made up of very small particles, which is usually sodium bicarbonate, potassium bicarbonate, or ammonium phosphate-based, with added material.

They are supplemented by specific treatment to offer resistance to packing that carry resistance to moisture absorption and the proper flow capabilities. This powder smothers fires by forming a barrier between the fuel and source of oxygen. Wet chemical powder can also be used for fires caused by various organic materials such as coal, fabrics, wood, textiles, cardboard and paper.

Types of Dry Chemical Powder:

The dry chemical powders are either sodium bicarbonate or potassium bicarbonate based. In most cases, the powder is made up of the sodium bicarbonate type. This type of powder is generally white in colour. We have another type which is purple K, or PK dry chemical powder, which is based on potassium bicarbonate.

Dry Chemical Powders are commonly formulated for putting out fire. The powders are suitable for combating fire in combustible materials, such as cloth, wood, rubber, paper and plastics. These chemicals are also used for flammable liquid, gases and grease.

Dry Chemical Powder gets increased demands during the summer season because of frequent breaking out of fire at different places. Cognizant of the demands in the local and international markets, sellers at Tradeindia maintain a large stock of Dry Chemical Powder. Buyers looking forward to buy the chemicals in bulk quantity may send their requirements through text message or email. 

FAQs:

What is ABC powder used for?

ABC dry chemical powder is used to combat fires in common combustible materials such as paper, cloth, rubber, wood, and plastics (Class A) as well as fires in flammable liquids, gases and greases (Class B) and fires that covers electrical equipment (Class C).

What is in a dry chemical powder?

A dry chemical powder contains sodium bicarbonate (NaHCO₃), or baking soda, potassium bicarbonate (KHCO₃), or mono-ammonium phosphate ((NH₄) H₂PO₄). These chemicals help coat the fuel and smother the fire.

What is CO₂ fire extinguisher?

Carbon dioxides are designed for Class B and C fires alone, which means it can work upon flammable liquid and electrical equipment. It works by displacing oxygen, or taking away the oxygen element of the fire triangle. Since CO₂ is very cold as it comes out of the extinguisher and it cools the fuel as well.

What is the composition of dry chemical powder?

The dry chemical powder is commonly made up of bi-carbonates of alkali materials and potassium chloride with additives so that it becomes water repellent, free flowing and conforming to various requirements working against the fire.
