Key properties and testing methods of industrial floor coatings
Industrial floor coating refers to the coating used for the ground of industrial plants, logistics warehousing, parking lots, sports stadiums and other places. It has the characteristics of wear resistance, corrosion resistance, dust resistance, and non-slip. Its application fields are wide, such as pharmaceutical factory, electronics factory, automobile factory, food factory, machinery factory, warehouse, logistics center, airport, hospital, school and so on.
The following are the common key properties of industrial floor coatings and the corresponding testing instruments and testing steps:
Key properties and testing methods of industrial floor coatings
| Performance name | Testing instrument | Detection steps |
|---|---|---|
| Force of adhesion | Adhesion tester | 1. Prepare the test board and test coating 2. Fix the test board on the test bench 3. Cut the grid pattern with the test scratch 4. Tape the grid at the slit of the pattern 5. Apply glue to the coating surface 6. Apply paint to the glue with a test brush 7. Wait for curing and peeling |
| hardness | Impression hardness tester | 1. Prepare test samples 2. Press the sample surface with a round steel ball of the specified mass 3. Measure the imprint diameter 4. Calculate the hardness value according to the formula |
| Chemical resistance | Chemical solutions and test tubes | 1. Prepare test samples 2. Prepare different chemical solutions 3. Soak the sample in the chemical solution 4. Observe the changes of the coating surface |
| Wear resistance | Wear testing machine | 1. Prepare test samples and wear testing machine 2. Fix the sample on the test machine 3. Load a certain quality of grinding wheel and mortar 4. Run the testing machine for a certain time 5. Check the wear of the coating surface |
| Water resistance | Water immersion tester | 1. Prepare test samples 2. Apply a coating of the specified thickness to the surface of the sample 3. Soak the sample in the water immersion tester for a certain time 4. Take out the sample and observe the changes of the coating surface |
| Salt spray resistance | Salt spray test chamber | 1. Prepare test samples 2. Apply a coating of the specified thickness to the surface of the sample 3. Expose the sample in the salt spray test chamber for a certain time 4. Take out the sample and observe the changes of the coating surface |
| Temperature resistance | Thermal circulation box | 1. Prepare test samples 2. Apply a coating of the specified thickness to the surface of the sample 3. Place the sample in a thermal circulation box for cyclic heating |
