Acrylic paint is a kind of paint made of acrylic acid and its copolymer as the main raw material, adding additives and solvents. Acrylic coatings have excellent weather resistance, chemical corrosion resistance, and strong adhesion. They are widely used in the fields of anticorrosion, decoration, and coating of metals, plastics, glass, ceramics, and other materials in industries such as construction, automobiles, ships, furniture, electronics, and machinery.
| Performance name | Equipment used | Detection steps |
|---|---|---|
| Coating properties at room temperature | Coating Thickness Gauge, scratch resistance testing machine | 1. Measure the thickness of the coating film with a coating Film Thickness Gauge; 2. Use a scratch resistance Tester to test the coating film |
| hardness | Pencil Hardness Tester, Thickness Tester | 1. Use a pencil Hardness Tester to test the hardness of the coating surface; 2. Use a coating Thickness Gauge to measure the coating thickness |
| chemical resistance | Corrosion Test Chamber, microscope | 1. Place the coating sample in a corrosion 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 |
| weather resistance | Constant temperature and Humidity Chamber, artificial climate aging chamber, microscope | 1. Place the coating sample in a constant temperature and Humidity Chamber or an artificial climate aging box to simulate the climate change in the natural environment; 2. Regularly 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 |
| environmental friendliness | Volatile Organic Compound Tester | 1. Place the coating sample in a volatile organic compound Tester; 2. Measure the content of volatile organic compounds in the coating sample |
| 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 |
| construction performance | Casting meter, drying time Tester | 1. Use a flow meter to test the fluidity of the coating; 2. Use a drying time Tester to test the drying time of the coating |
| antibacterial properties | Antibacterial Performance Tester | 1. Put the coating sample in the antibacterial performance Tester; 2. Test the inhibition rate and sterilization rate of the coating on the bacteria |
For each test, the specific steps will be different, and you need to refer to the corresponding test standards or methods. Some 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.
