Phosphorus-free iron-aluminum common lamps

The phosphorus-free iron-aluminum conversion common technology used in lamps is an environmentally friendly process for surface treatment of metal materials such as iron and aluminum during the manufacturing process of lamps. The following is an introduction to its principles, advantages, applications, etc.:

principle

Traditional metal surface treatment processes often use phosphorus-containing conversion agents to form a phosphate conversion film on the metal surface through chemical reactions to improve the metal's corrosion resistance, wear resistance, and coating adhesion. The phosphorus- free conversion iron-aluminum common technology abandons phosphorus-containing compounds and uses other phosphorus-free chemicals, such as organic carboxylic acids, fluorides, zirconium salts, titanium salts, etc., to form a conversion film with similar functions on the surfaces of metals such as iron and aluminum through a series of complex chemical reactions and physical adsorption processes. This conversion film can effectively isolate the metal from the external environment and prevent the metal from rusting and corroding. At the same time, it provides a good foundation for subsequent coating and other processes and enhances the bonding between the coating and the metal surface.

advantage

Good environmental protection: Phosphorus is one of the main elements that cause eutrophication of water bodies. Phosphorus-free conversion technology avoids the discharge of phosphorus-containing wastewater, greatly reduces pollution to the environment, and complies with environmental protection requirements and the development trend of relevant regulations.

Iron and aluminum common: This technology can be applied to different metal materials such as iron and aluminum at the same time, with good versatility, reducing the cost increase and process complexity caused by different materials requiring different processing techniques.

Excellent performance: The conversion film has good corrosion resistance, water resistance and chemical resistance, which can effectively protect the metal substrate and extend the service life of the lamp. At the same time, the conversion film has a strong bonding force with subsequent coatings such as paint, which can improve the adhesion and durability of the coating, making the surface of the lamp more beautiful and durable.

Simple process: The phosphorus-free conversion process is relatively simple, easy to operate, easy to control, and can improve production efficiency and reduce production costs. Moreover, the process does not require special equipment and complex process flow, and is easy to transform and apply on existing lamp production lines.
