The effect of the release agent on concrete is closely related to the appearance of the concrete itself, the flatness of the formwork and the vibration when pouring the concrete. The release agent does play its unique role; choosing different types of release agent, the effect is different, if you understand The use of various release agents can achieve the desired effect of concrete appearance.
In view of the problems that concrete products and formwork in the construction industry are easy to rust when stored in the market, there are air bubbles on the concrete surface, the concrete surface is easy to contaminate, and it is difficult to remove and clean the formwork, etc., a high-efficiency concrete release agent has been introduced. Made with active additives. The product is stable and superior in performance, and is a high-performance concrete release material necessary to create high-quality projects.
1. Good demoulding performance.
When removing the formwork, the release agent is required to separate the formwork from the concrete smoothly, keeping the surface of the concrete smooth and the edges and corners neat.
2. Easy to apply and quick to form. Easy to clean after demolding.
The release agent can not only be painted, but also sprayed. The molding should be fast (usually within 20 minutes), and it is easy to remove after demolding, so as not to affect the construction progress and product productivity.
3. Does not affect the decorative effect of the concrete surface, leaves no dipping marks on the concrete surface, and reverses yellowing and discoloration.
4. It does not pollute the steel bar and is harmless to the concrete.
Does not affect the grip of concrete and steel. Do not change the setting time of the concrete mixture and must not contain harmful substances.
5. Protect the template. Extend the life of the template.
The wood mold release agent should be able to penetrate the surface of the wood mold, play a role in maintaining and filling the formwork, and prevent the wood and corners from swelling, swelling, cracking and defects after repeated use. The steel mold release agent should have the effect of preventing the steel mold from rusting and causing the concrete surface to rust.
6. Good stability.
The concrete release agent should have good stability and long storage period.
7. Has good water resistance and weather resistance.
The release agent used in on-site construction and open-air prefabrication field should have a certain resistance to rain erosion, that is, the release agent on the formwork should be able to maintain the release performance; After pouring, the formwork does not stick to the concrete surface, and it is not easy to remove the formwork or affect the cleanliness of the concrete surface. Its main function is to form a thin film on the formwork and concrete surface to isolate the two, also known as a release agent.
