Key properties and testing methods of furniture coatings
Lighthouse coating is a special anticorrosive coating used for the protection of Marine buildings such as Marine lighthouses and offshore drilling platforms. It has good seawater resistance, UV resistance and weather resistance, which can effectively prevent the erosion of the Marine environment on the building and ensure the long-term stable operation of the building.
Furniture coating is a kind of special coating, widely used in furniture manufacturing industry. It is characterized by a good decorative effect, can make the furniture surface smooth, beautiful, durable, but also to protect the furniture surface from external damage. Furniture coating is mainly divided into two kinds of solvent and water, applied to a variety of different materials of furniture surface, including wood furniture, metal furniture, plastic furniture, etc. (Note: the use of furniture paint requires special attention to environmental and personal safety. Read the product instructions carefully before use and take appropriate safety measures.)
Key properties and testing methods of furniture coatings
The following table lists the key properties of furniture coatings to be tested, the used instruments and equipment, and the testing steps:
| Detection performance | Instrument and equipment | Detection steps |
|---|---|---|
| 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 test piece into the required 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 test piece are peeled off; 5. Record test results according to test standards. |
| hardness | Pencil hardness tester | 1. Prepare test instruments and samples; 2. Draw minerals with 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 test standards. |
| Scratch resistance | Scratch tester | 1. Prepare test instruments and samples; 2. Place the sample on the test bench; 3. Use the specified scratch tool to scratch the surface of the sample; 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 change of the sample surface within the specified time; 5. Record test results according to test standards. |
