There are mainly four reasons why the powder coating easy to fall off on the 316 Marine Grade stainless steel security screens:(For more informations about security screens, please click www.aamesh.com)
1.the powder quality is not good; the main reason is because the powder particle size is not the same. This will cause the powder can’t be melted sufficiently in the high temperature,so its adsorption force will naturally become smaller.
We MAISHI WIRE MESH MANUFACTURE GROUP use Akzonobel powder brand, when purchase the powder, the powder coatedcompany send testing card firstly, then delivery the powder to our factory if testing card is acceptable. Please rest assured our powder quality is good.
2. the temperature is not enough; the drying oven temperture must reach to or more than 200 degrees before the mesh goes into the spray chamber, if the temperature can not reach the standard temperture, then the powder can’t be melted sufficiently in the high temperature, and causing the powder to be fixed on the net.
We MAISHI WIRE MESH MANUFACTURE GROUP always double powder coating,heated to 210±5℃, melting the powder time control in 18-20mins to make the powder be melted sufficiently, to avoid the powder coating fall off.
3. the quality of the mesh; the most important is to keep the mesh clean and hygienic before spraying, the mesh surface can not have dust and grease, if the mesh surface is not clean will affect the powder adsorption. MAISHI WIRE MESH MANUFACTURE GROUP stainless steel security screens always be washed by acid to remove oil and burrsetc on mesh surface.
4.the net surface itself is curved, so sticky not very well.
