Key properties of furniture coatings and their detection methods
Lighthouse coating is a special anti-corrosion coating, which is used for the protection of Marine buildings such as lighthouses and offshore drilling platforms. It has good seawater resistance, UV resistance and weather resistance, which can effectively prevent the erosion of the building by the Marine environment and ensure the long-term stable operation of the building.
Furniture coating is a special coating, which is widely used in furniture manufacturing industry. It is characterized by a good decorative effect, can make the furniture surface smooth, beautiful, durable, but also can protect the furniture surface from external damage. Furniture paint is mainly divided into two kinds of solve-based and water-based, applied to a variety of different materials of furniture surface, including wood furniture, metal furniture, plastic furniture and so on. (Note: The use of furniture paint requires special attention to environmental and personal safety, carefully read the product instructions before use, and take corresponding safety measures)
Key properties of furniture coatings and their detection methods
The following table lists the key properties to be tested for furniture coatings, the instruments used and the testing steps:
| Performance of detection | Instruments and equipment | Step of detection |
|---|---|---|
| Difference of color | Optical colorimeter | 1. Standard whiteboard calibration instrument; 2. Place the instrument in the test position and open the instrument; 3. Wipe the surface of the sample to be tested with a cloth and place the sample in the test position; 4. Measure and record the results. |
| Force of adhesion | Adhesion tester | 1. Prepare the test instrument and attach the test piece; 2. Use the cutting tool to cut the specimen into the desired shape and size; 3. Paste the test piece on the tested surface and apply the required load; 4. After the load is applied, check whether the surface and bottom of the specimen are peeled off; 5. Record test results according to test standards. |
| Hardness of hardness | Pencil hardness tester | 1. Prepare test instruments and samples; 2. Draw minerals of different hardness on the surface of the sample with pencil; 3. Check whether the brush has scratched the surface of the sample; 4. Record test results according to testing standards. |
| Scratch resistance | Scratch tester | 1. Prepare test instruments and samples; 2. Place the sample on the test bench; 3. Use the designated scratch tool to scratch the sample surface; 4. Observe the changes of the sample surface and record the test results according to the testing standards. |
| Water resistance property | Constant temperature and humidity test chamber | 1. Prepare test instruments and samples; 2. Place the sample in the constant temperature and humidity test chamber; 3. Set the required temperature and humidity conditions; 4. Take out the sample and check the surface changes of the sample within the specified time; 5. Record tes |
