Polymer cement-based waterproof coating is a kind of waterproof coating made of polymer as the main raw material by adding cement, fillers, additives, etc. It has the characteristics of good adhesion, water resistance, temperature resistance, and chemical corrosion resistance, which can effectively prevent water penetration and protect the surface of buildings from water and moisture. Polymer cement-based waterproof coatings are widely used in buildings, underground engineering, water conservancy engineering and other fields, such as roofs, walls, basements, pools, water towers and other places, to improve the waterproof performance and service life of buildings.
Detection performance and instrument
| Performance name | Equipment used | Detection steps |
|---|---|---|
| Adhesion | Adhesion Tester | 1. Scratch a straight line on the coating surface; 2. Use an adhesion Tester to measure the adhesion of the coating surface |
| film thickness | Coating Thickness Gauge | 1. Measure the film thickness of the coating with a Film Thickness Gauge |
| Water resistance | Water Immersion Tester | 1. Place the coating sample in the water immersion Tester; 2. Measure the water resistance of the coating sample within a certain period of time |
| Temperature resistance | Thermal cycle Test Chamber | 1. Place the coating sample in the thermal cycle Test Chamber; 2. Observe the performance change of the coating sample under high temperature and low temperature environment |
| Chemical resistance | Chemical Resistance Chambers, Microscopes | 1. Place the coating sample in a chemical resistance 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 |
| 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 |
| elongation at break | Elongation at break Tester | 1. Place the coated sample in the elongation at break Tester; 2. Test the elongation at break of the coated sample |
When testing special properties such as adhesion, water resistance, and chemical corrosion resistance, it is necessary to pay attention to the control of the testing environment and the selection of testing time to ensure the accuracy and reliability of the test results. During the testing process, it is also necessary to pay attention to the source and quality of the samples and paint samples used to ensure the representativeness and reliability of the test results.
