What are the characteristics of epoxy resin floor precautions
Floor paints are often used in structures such as industrial civil buildings, roads, bridges, and airport runways. One epoxy resin floor is used more frequently. It is characterized by its high strength and excellent comprehensive performance. It is used as a repair and reinforcement material for the overburden abrasion protection layer of hydraulic concrete over-flow surface and the damaged parts such as erosion, abrasion and cavitation erosion. Next we know about the epoxy floor. The characteristics of it.
Epoxy floor features
1. Excellent adhesion: Epoxy floor coating has many hydroxyl and ether bonds, so it can be adsorbed with the bottom material. And the volume shrinkage of the epoxy resin is low, so the paint film has excellent adhesion to metal, ceramic, glass, concrete, wood and other polar substrates.
2. Epoxy resin floor has a certain wetting force on the wet side, especially when polyamide resin is used as a curing agent, it can be made into underwater construction coating and can be applied by squeezing the water on the surface of the object. It can be used underwater. Structural repairs and corrosion protection of underwater structures.
3, epoxy floor itself is not high molecules, with a variety of curing agents can be made without solvent, high solids powder coatings and water-based coatings, in line with environmental requirements, and can obtain thick film coating.
4. Epoxy resin floor contains two active groups: epoxy group and hydroxyl group. It can be mixed with polyamines, polyamide resins, phenolic resins, amino resins, polyisocyanates, etc. to make a variety of coatings that can be dried at room temperature. Cocoa is baked at high temperatures to meet different construction requirements.
Epoxy floor construction requirements
1. It is required that the base surface of the cement base be firm, strong, and not shelling, and it is better to pour the cement together with the concrete base so as to prevent the shelling phenomenon of mortar and the concrete foundation is dried for 28 days. The first floor needs waterproofing.
2. It is required that the surface of the cement base surface cannot be sand, the hardness is good, and there is no phenomenon of cement powdering.
3, the surface is flat, no bumps, cellular pockmarks, concrete defects and so on.
4. The PH value of the floor surface should be between 6.8-8.0.
5, the ground no oil, wax, other paint, latex paint and other residues; if there is a special solution cleaning or polishing treatment
Epoxy Floor Precautions:
Avoid construction under low temperature and high humidity conditions; after the two-component materials are mixed, they should be constructed in a short time; after the coating is completed, the maintenance period should be fully used before it can be put into use; according to the conditions of substrate flatness and usage requirements, it is decided Coating thickness. The worse the flatness of the ground, the thicker coating system is used. The greater the coating load is, the thicker the coating should be. If the coating is too thin, it will be easily damaged during use. For example, the floor on the first floor needs to be waterproofed.
Summary: The above is Xiaobian's introduction to the epoxy floor , I hope to be helpful to everyone.
