Polymer cement waterproof coatings: testing performance, methods, instruments

Polymer cement waterproof coating is a waterproof coating based on polymer and cement as the main raw material, which has good waterproof performance and durability. It is used in a wide range of fields, including construction engineering fields such as basements, bridges, water conservancy projects, and sewage treatment plants, as well as transportation infrastructure fields such as subways and tunnels.

Key performance and equipment

Detection steps

Specific testing steps for polymer cement waterproof coatings:

1. Cohesive strength: apply the paint sample on a suitable substrate, and after it dries, use a Tensile Testing Machine to perform a tensile test on it to obtain the parameter of the cohesive strength of the sample.

2. Water resistance: Soak the paint sample in water and observe its changes. If peeling or blistering occurs, it indicates that the water resistance is poor.

3. Alkali resistance: Use an alkalinity meter to measure the paint sample to obtain its alkali resistance in an alkaline environment.

4. Durability: put the paint sample into the Pirelli testing machine, conduct a simulated performance aging test, and observe its performance changes to evaluate its durability.

5. Impermeability: Use a hydrostatic Tester to conduct a permeability test on the coating film sample to evaluate its impermeability.

6. Weather resistance: Place the paint sample in a constant temperature and Humidity Chamber for a simulated performance aging test, and observe its performance changes to evaluate its weather resistance.

7. Construction performance: Use a rheometer to test the coating sample to obtain its rheological performance parameters, such as viscosity, shear modulus, etc., to evaluate its construction performance.
