PEG-12 Dimethicone Manufacturers introduced the requirements of carbon fiber felt adhesive reinforcement: cracked floors are reinforced with carbon fiber cloth, but before the construction of carbon fiber cloth reinforcement, the following treatment methods need to be taken for the cracked floors, which is to take a picture of the ceiling to ensure that it is repaired Restore renovation. The rectification area shall be covered with agricultural film to avoid pollution.

Remove the cement mortar leveling layer or paint layer around the crack. In order to facilitate the use of carbon fiber felt adhesive, the reinforced concrete base should be polished and cleaned in accordance with the specifications and construction techniques. If the concrete surface has peeling, honeycomb, corrosion and other deterioration phenomena, the parts should be removed. For large-area inferior layers, polymer cement mortar should be used to repair. If necessary, seal the cracks first.

Use concrete angle grinders, grinding wheels (sandpaper) and other tools to remove impurities such as scum and oil on the surface of the concrete. The concrete of the base surface of the component should be smoothed, especially the protruding part of the surface should be smoothed, and the corners should be chamfered and polished into an arc. Use a blower to clean the concrete surface and keep it dry. The EC high-strength polymer mortar developed and produced by the Chinese Academy of Building Sciences is used for the repair of surface depressions.

After part of the concrete structure is cleaned by chiseling, it is repaired and repaired with epoxy mortar that is one level higher than the original structure concrete to achieve a solid and smooth surface. The floor and beams are reinforced with carbon fiber according to the following scheme. The cloth reinforcement and repair structure of carbon fiber felt adhesive should be completed by a professional construction team familiar with the technical construction process, and there should be a reinforcement repair plan and construction technical measures.

Use high-performance, high-bonding strength A-grade epoxy fiber cloth adhesive. The tensile strength of carbon fiber cloth is ≥3500MPa. When bonding carbon fiber cloth and reinforced concrete structural slabs, a binder with good compatibility with the substrate and carbon fiber should be selected. Before use, the carbon fiber cloth and adhesive performance test passed. Construction process: construction preparation: scaffolding erection, surface treatment, base resin preparation and painting, leveling material preparation and uneven repair, resin or resin pasting, carbon fiber cloth pasting, surface protection, repair coating, scaffolding Dismantle, clean and clean.

The carbon fiber felt adhesive must provide a certificate and inspection report, and the carbon fiber cloth must have a certificate and inspection report. The crimped steel plate and nail shot must have a certificate and inspection report. Main machinery: angle grinders, blowers, roller presses and other auxiliary facilities that affect the construction of the carbon fiber cloth.

Through the above introduction, 1,3,5,7-Tetramethylcyclotetrasiloxane Manufacturers hopes that you can simply refer to the content of this article in future use.
