Shell powder paint is a new type of environmentally friendly paint made of shell powder as the main raw material through special processes 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 protection performance. Shell powder coatings are widely used in interior decoration, furniture, handicrafts 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 that need to be tested for shell powder coatings and the instruments and equipment that need to be used:
| performance factor | equipment |
|---|---|
| color | Colorimeter |
| Adhesion | Adhesion Test Equipment |
| Water resistance | Water resistance test equipment |
| Pollution Resistance | Pollutant adhesion performance testing equipment |
| luster | Gloss meter |
| wear resistance | Abrasion testing machine |
Detection method steps
The following are the properties and testing steps that need to be tested for shell powder coatings:
Color: Use a color difference meter to measure the color value of the shell powder paint sample, and compare it with the standard color value to evaluate the degree of color difference of the sample.
Adhesion: Stick the adhesive tape on the surface of the shell powder coating sample, tear it off with force, and observe whether the coating and the substrate are peeled off or peeled off.
Water resistance: Soak the shell powder coating sample in water for a certain period of time, take it out and dry it, and observe whether the coating is cracked or peeled off.
Pollution resistance: apply the pollutants on the surface of the shell powder coating sample, let it stand for a certain period of time, clean it with water or detergent, and observe whether the coating falls off or changes color.
Gloss: Use a gloss meter to measure the gloss value of shell powder paint samples.
Abrasion resistance: Use an abrasion testing machine to conduct an abrasion test on the shell powder coating, record the amount of abrasion, and evaluate the abrasion resistance of the sample.
For some shell powder coatings with special properties, it may be necessary to use other instruments and equipment for testing, and the specific operation steps will also be different.
