What are the reasons for the security screen coating falling off

Security screens do a good job in not only preventing theft and mosquitoes, but also in many other aspects, such as sealing and heat preservation performance, practicability, safety, and ventilation. However, it will also have malfunctions that are unavoidable with excellent performance. Here is an analysis of the reasons that cause the powder coating of the security screen falling off.
 
1. Insufficient temperature: Pay special attention to the use of high-quality powder. Before entering the stainless steel mesh to reach the spray chamber, the temperature of the oven needs to reach 200 degrees or more. If the temperature is not reached, the powder will melt at a high temperature. If insufficient, it will not be fixed on the mesh.
 
2. The powder is of low quality: the main reason is that the particle size of the powder is different. This will cause the powder to be insufficiently melted at high temperatures, so its adsorption force will naturally become smaller.
 
3. The quality of the mesh: The main thing is that the stainless steel mesh protective screen mesh must be clean and hygienic before spraying. There must be no dust or grease on the surface. If the surface of the mesh is unsanitary, it will also affect the adsorption of the powder.
 
In summary, if the manufacturing temperature, powder quality, and mesh quality of the security screen are not enough, it will have a great impact on its use effect. Therefore, we should not only pay special attention to these three aspects when manufacturing but also when choosing materials. Pay attention to the quality of powder and mesh, otherwise, the phenomenon of powder surface falling off cannot be improved.
 
MAISHI chooses Akzo powder and 316 stainless steel wire mesh as raw materials. The temperature is strictly controlled during production to ensure quality. Please feel free to contact us if you need premium-quality security screens.
