Main properties and testing equipment of shell powder coating
Shell powder coating is a new kind of environmental protection coating made of shell powder as the main raw material through special process and additives. It has the characteristics of good air permeability, mildew resistance and water resistance, and also has the unique decorative effect of shell powder and good environmental performance. Shell powder coating is widely used in interior decoration, furniture, crafts and other fields, adding unique artistic charm to buildings with its unique shell texture and natural texture.
Test performance equipment
The following are the key properties of shell powder coating to be tested and the equipment to be used:
| Factor of performance | Instruments and equipment |
|---|---|
| Color and gloss | Color difference meter |
| Force of adhesion | Adhesion test equipment |
| Water resistance property | Water resistance test equipment |
| Pollution resistance performance | Pollutant attachment performance testing equipment |

Detection method steps
The following are the properties of shell powder coating to be tested and the testing steps:
Color: The color value of shell powder coating sample was measured by colorimeter, and compared with the standard color value to evaluate the degree of color difference of the sample.
Adhesion: Stick the tape to the surface of the shell powder coating sample, tear it off with force, and observe whether the coating and the substrate fall off or peel off.
Water resistance: Soak the shell powder coating sample in water for a certain time, take it out to dry, and observe whether the coating cracks, peeling and other phenomena.
Main properties and testing equipment of shell powder coating
Pollution resistance: Apply the pollutants on the surface of the shell powder coating sample, leave it for a certain time, clean it with water or cleaning agent, and observe whether the coating falls off or changes color.
Gloss: Use gloss meter to measure the gloss value of shell powder coating sample.
Wear resistance: The wear testing machine was used to test the shell powder coating, record the amount of wear, and evaluate the wear resistance of the sample.
For some special properties of shell powder coating, it may be necessary to use other instruments and equipment for testing, and the specific operation steps will be different
