Texture paint is a kind of paint with texture, concave-convex feeling or special effects such as stone imitation and wood imitation. They are usually composed of raw materials such as basic paints, pigments, fillers, and additives, and achieve special texture effects by adjusting particle size, shape, and distribution. The application fields of texture coatings include architecture, home decoration, art, electrical appliances, furniture, etc. It is suitable for various surface coatings such as walls, ceilings, floors, and furniture. It can improve the decorative effect and perception of products, and create unique visual effects.
Detection performance and method steps
| Performance name | Equipment used | Detection steps |
|---|---|---|
| texture effect | Visual observation, hand observation | 1. Use the naked eye to observe the texture effect of the paint surface; 2. Use the hand feel to observe the unevenness and feel of the paint surface |
| chromatic aberration | Colorimeter | 1. Put the paint sample in the color difference meter; 2. Measure the color difference between the paint sample and the standard color plate |
| Scratch resistance | Scratch resistance testing machine | 1. Test the scratch resistance of paint samples using a scratch resistance Tester |
| Wear resistance | Abrasion testing machine | 1. Testing the abrasion resistance of the paint samples using an abrasion Tester |
| Chemical resistance | Chemical Resistance Chambers, Microscopes | 1. Place the coating sample in a chemical resistance test box and expose it to chemical reagents; 2. Observe the changes of the coating sample and use a microscope to observe its surface morphology |
| Adhesion | Peel Strength Tester | 1. Paste the coating sample on the material to be tested; 2. Use a peel strength Tester to conduct a peel test to test the adhesion of the coating |
| density | Density meter | 1. Place the paint sample in a density meter; 2. Measure the density of the paint sample |
| pH value | pH meter | 1. Place the paint sample in the pH meter; 2. Measure the pH of the paint sample |
For each test, the specific steps will be different, and you need to refer to the corresponding test standards or methods. Commonly used standards or methods include: ASTM, ISO, GB/T, etc. During the detection process, attention should be paid to the accuracy and repeatability of the instrument, as well as the preparation and processing of the sample. When testing the texture effect, visual observation and hand feeling observation are very important steps, which need to be judged by experienced testing personnel.
In addition, different types of texture coatings may also require some special performance testing. For example, stone-like coatings need to be tested for stone-like effects, and microscopes can be used to observe the effects of stone grains and stones on the surface; wood-like coatings need to be tested for wood-like effects, and wood grains and wood grain depths on the surface can be observed by hand. During the testing process, it is necessary to pay attention to the performance of the test and the corresponding test method, as well as the use requirements and application scenarios of the coating.
