Lighthouse coating is a special anti-corrosion coating, which is used for the protection of marine structures such as offshore lighthouses and offshore drilling platforms. It has good seawater resistance, ultraviolet resistance, and weather resistance, which can effectively prevent the erosion of buildings by the marine environment and ensure the long-term stable operation of buildings.
Furniture coating is a special coating widely used in furniture manufacturing. It is characterized by a good decorative effect, which can make the surface of the furniture smooth, beautiful and durable, and at the same time protect the surface of the furniture from external damage. Furniture coatings are mainly divided into two types: solvent-based and water-based, which are applied to furniture surfaces of various materials, including wooden furniture, metal furniture, plastic furniture, etc. (Note: The use of furniture coatings requires special attention to the environment and personal safety, carefully read the product manual before use, and take corresponding safety measures)
The following table lists the key properties to be tested for furniture coatings, the instruments and equipment used, and the testing steps:
| Detection performance | equipment | Detection steps |
|---|---|---|
| chromatic aberration | Light Colorimeter | 1. Calibrate the instrument with a standard white board; 2. Place the instrument at the test position and turn on the instrument; 3. Wipe the surface of the sample to be tested with a cloth and place the sample at the test position; 4. Measure and record the results. |
| 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. Stick the test piece on the surface to be tested and apply the required load; 4. After applying the load, check whether the surface and bottom of the test piece are peeled off; 5. Record the test results according to the testing standards. |
| hardness | Pencil Hardness Tester | 1. Prepare test instruments and samples; 2. Use a pencil to draw minerals with different hardness on the surface of the sample; 3. Check whether the paintbrush scratches the surface of the sample; 4. Record the test results according to the 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 surface of the sample; 4. Observe the changes on the surface of the sample, and record the test results according to the testing standards. |
| Water resistance | Constant temperature and humidity Test Chamber | 1. Prepare the test instruments and samples; 2. Place the samples in the constant temperature and humidity Test Chamber; 3. Set the required temperature and humidity conditions; 4. Take out the samples within the specified time and check the changes on the surface of the samples; 5. Record the test results according to the testing standards. |
