Good construction of industrial wear-resistant floor paint will have a significant impact on its later use. We must strictly follow the construction requirements for the construction of industrial wear-resistant floor paint, so that the factory floor can have better quality and better development. The development of industry has increasingly demanded a communist operating environment, which is a driving force for factory flooring. Under such environmental requirements, the emergence of industrial wear-resistant floor paint has solved the difficulties faced by factory floors. How to judge the quality of industrial wear-resistant floor paint construction?
After the construction of industrial wear-resistant floor paint, strict quality acceptance is required. So what are the quality acceptance standards for industrial wear-resistant floor paint?
1. Hardness testing standard: When the ambient temperature is 25 ℃, the hardness should reach about 80% of the cured state within 2-3 days after construction. The pencil hardness of epoxy wear-resistant floor coating should be greater than 2H to ensure compliance with industrial production requirements.
2. Bubble detection standard: flat coating type, mortar type without bubbles.
3. Color detection standard: No floating color or flower phenomenon, uniform and consistent color.
4. Smooth detection standard: The floor surface should be flat and smooth, and the glossiness should meet the design requirements. Flat coating is glossy, while water-based coating is semi glossy to matte.
5. Anti slip effect testing standard: The anti slip surface effect of orange peel and mortar should be very obvious.
6. Leveling: Good leveling, no trowel marks, and the large interface is basically flat.
7. Other surface quality details: Industrial wear-resistant floor paint is a functional floor coating with decorative functions, so the surface must not have impurities or visible film defects.
8. Fullness: The coating of industrial wear-resistant floor paint should be full.
The detection of fineness of industrial wear-resistant floor paint and coating, as well as the thickness and size of pigments and filler particles in the coating components, and the degree of uniform dispersion in production, have a significant impact on the smoothness and gloss of the coating appearance. Therefore, it is necessary to test the quality indicators of coating fineness to ensure that it meets the indicators specified in the coating quality standards. The commonly used scraper fineness meter can detect the fineness index of coatings.
The detection of viscosity of floor paint coatings is divided into relative viscosity, kinematic viscosity, and absolute viscosity. During the coating process of industrial wear-resistant floor paint, the viscosity of the coating commonly measured by the Tu-4 viscometer on the production site is called the relative viscosity. In addition to the commonly used Tu-4 viscometer, viscosity testing also includes Tu-1 viscometer, drop ball viscometer, and less commonly used rotary viscometer for detecting high viscosity.
