The amount of high calcium powder added will have multiple effects on the performance of powder coatings.
Guigang Lime Plant: Appearance aspect
-When added in small amounts, it has little effect on the glossiness of the coating. As the amount of addition increases, the glossiness of the coating will gradually decrease, as high calcium powder will to some extent damage the smoothness of the coating surface.
-When the amount added is too high, it may cause the coating to have a grainy texture, affecting the smoothness and delicacy of the coating.
Guigang Lime Plant: Mechanical Performance
-In terms of hardness, adding a moderate amount of high calcium powder will increase the hardness of the coating. But if the amount added is too high, the coating will become brittle, the flexibility will decrease, and the coating is prone to cracking when subjected to external impact or bending.
-In terms of wear resistance, an appropriate amount of high calcium powder can improve the wear resistance, but excessive addition may lead to a decrease in the cohesion of the coating, making it more prone to wear and peeling during the friction process.
Guigang Lime Plant: Chemical Properties
-When the appropriate amount of high calcium powder is added, it can enhance the chemical corrosion resistance of the coating to a certain extent. However, excessive addition can reduce the density of the coating, making it easier for chemicals to penetrate into the coating, resulting in a decrease in corrosion resistance.
