What are the general product materials of 5KG Carbon Steel Portable CO₂ Fire Extinguisher?

5KG Carbon Steel Portable CO₂ Fire Extinguisher is an efficient fire extinguishing equipment widely used in many occasions. Its core material is particularly important in the design and production process. The material of the fire extinguisher affects its service life and also determines the performance and safety of the fire extinguisher. performance and durability.

1. Carbon steel material
The bottle body of the 5KG portable CO₂ fire extinguisher is mainly made of carbon steel. Carbon steel is an iron-carbon alloy with a carbon content between 0.02%-2.11% and has high strength and toughness. Carbon steel has good pressure resistance and impact resistance, can withstand the high-pressure carbon dioxide gas in the fire extinguisher, and is not prone to deformation or rupture under high pressure.
Another significant advantage of carbon steel is its good processing properties. During the production process, carbon steel can be formed into bottles of different thicknesses through rolling, stretching and other processes while maintaining its good mechanical properties. This makes the fire extinguisher not only strong and durable, but also lightweight, making it easy for users to carry and use.

2. Internal anti-corrosion treatment
In order to prevent carbon dioxide from corroding the interior of the fire extinguisher, the inner wall of the 5KG carbon steel portable CO₂ fire extinguisher usually undergoes special anti-corrosion treatment. Carbon dioxide will produce certain chemical reactions with metal materials under high pressure, and long-term use may cause corrosion of the inner wall of the bottle. In order to solve this problem, manufacturers usually coat the inside of the bottle with a layer of corrosion-resistant material, such as epoxy resin or polymer coating. These coatings can effectively isolate the direct contact between CO₂ gas and carbon steel, extending the life of the fire extinguisher. service life.

3. External spraying treatment
The exterior of the fire extinguisher is treated with high-quality spray coating. This coating enhances the aesthetics of the product and also provides anti-rust, anti-corrosion and anti-oxidation effects. In outdoor environments, fire extinguishers may be affected by external factors such as moisture and ultraviolet rays. The external spray coating can effectively prevent the surface of the fire extinguisher from rusting and aging, ensuring that it can still be used normally under harsh conditions.
Typically, spray coating uses a high-temperature cured polyester powder coating. This coating has strong adhesion and can adhere firmly to the surface of carbon steel. It also has good chemical resistance, UV resistance and impact resistance, allowing the fire extinguisher to remain in good condition during long-term storage and use. appearance and performance.

4. Nozzle material
The fire extinguisher nozzle is a key component of carbon dioxide injection. It is usually made of high temperature and corrosion-resistant metal or synthetic materials. Common nozzle materials include brass, stainless steel, etc. These materials are durable and chemically resistant, maintaining stable performance over long periods of use. In addition, the nozzle needs to have sufficient mechanical strength to prevent deformation or wear when high-pressure CO₂ gas passes through it.
Brass nozzles have become a common choice among CO₂ fire extinguishers due to their good thermal conductivity and corrosion resistance. It not only resists corrosion from carbon dioxide but also maintains stable performance in high-temperature environments. Stainless steel nozzles are suitable for applications requiring higher durability and pressure resistance due to their higher corrosion resistance and strength.

5. Other auxiliary materials
In addition to the bottle body and nozzle, the handle, pressure handle and other parts of the fire extinguisher are usually made of high-strength plastic or aluminum alloy. Aluminum alloy materials are often used to make the handles of fire extinguishers because of their lightness, corrosion resistance and high strength. The high-strength plastic material has good wear resistance and insulation properties, ensuring a comfortable grip and reducing the risk of slipping during use.
In addition, the fire extinguisher’s pressure gauge and seals are also made of high-quality materials. The housing of a pressure gauge is usually made of impact-resistant plastic or stainless steel to ensure accurate pressure display in a variety of environments. The seals are made of pressure-resistant and high-temperature-resistant rubber or polymer to ensure that the fire extinguisher will not leak during long-term storage.
