Barens C920 Room Temperature Blackening Agent for Steel Iron Metal Surface Treatment
The C920 Cold Blackening Agent for steel is an innovative solution for rust prevention and blackening treatment of steel components. This product serves as a highly effective alternative to traditional high-temperature alkaline blackening (bluing) processes. C920 offers numerous advantages, including simplicity of operation, user-friendly application, significant energy savings, flexible batch production capabilities, and high work efficiency, all tailored to meet production demands seamlessly.
One of the standout features of the C920 blackening process is its quick treatment time. This agent can be used at room temperature, allowing for easy immersion applications that create a uniform, pure black film on the surface of steel workpieces. The resultant black film exhibits excellent wear resistance; once treated with a sealing anti-rust oil through immersion or spraying, the black layer remains intact and does not rub off, maintaining its aesthetic and protective qualities.
C920 is suitable for various types of steel materials, including low carbon steel (A3, Q195, Q215, 45#), high carbon steel (60#, 65Mn, 72A, 82B), as well as chromium and silicon steels. However, it is not applicable for stainless steel materials. This versatility makes it widely used in various industries, including hardware manufacturing, machinery, springs, fasteners, valves, and other iron products requiring blackening treatment.
The application methods for the C920 Cold Blackening Agent include immersion and brush coating. For immersion, the concentrate should be diluted with water at a ratio of 1:2 to 1:5, with a treatment time of approximately 1 to 5 minutes, depending on the desired degree of blackness. It is essential to monitor the process to ensure optimal results, as both overexposure and underexposure can lead to unsatisfactory outcomes. For brush coating, the concentrate can be used directly or diluted with an equal amount of water, applying it evenly with a brush in 3 to 5 layers until the desired black finish is achieved. With high processing capacity, one kilogram of the blackening agent can treat approximately 5 square meters of surface area.
The performance advantages of the C920 Cold Blackening Agent are noteworthy:
1. **Rapid Film Formation and High Blackness**: The agent facilitates quick film formation with a deep black color, resulting in a dense coating.
2. **Good Wear Resistance and Color Stability**: The resulting film is uniform and pure black, demonstrating excellent wear resistance and color stability.
3. **Rust Prevention**: Once treated, components do not rust or change color upon storage, ensuring long-term protection.
4. **Energy Efficiency and Environmental Safety**: The product operates at room temperature, eliminating the need for high-temperature heating, which contributes to energy savings and environmental protection.
5. **Broad Applicability**: The C920 blackening agent can be used on various steel types, including low and high carbon steels, cast iron, manganese steel, and silicon steel.
6. **Low Operating Costs**: The solution is recyclable, which significantly reduces overall operating costs.
In summary, the C920 Cold Blackening Agent presents a modern and efficient approach to blackening and rust prevention for steel components, combining ease of use, environmental benefits, and economic efficiency in a single product.
