Expert: New material Caben carbon fiber cloth

China Paint Online News:
New building reinforcement materials - Caben carbon fiber cloth - in today's growing economy, a large number of old buildings were demolished and replaced, new buildings springing up! Cities are becoming more prosperous and bigger. But there is no denying that such an approach has led directly to a huge waste of social resources, and even caused huge environmental pollution. So why do some buildings that have not reached their end of life have to be demolished and replaced? Perhaps, some people will say that even if not reached the service life, but there are structural problems ah, in order to the people's lives and property safety, even if caused waste, caused pollution, must be rebuilt.
fact, some building structural problems can be repaired and strengthened on it, there is no need to tear down the reconstruction! At present, for the domestic construction reinforcement prospects are still very good, a large number of historic buildings in urgent need of reinforcement and repair. The main materials used in building reinforcement are carbon fiber cloth, carbon fiber board and other carbon fiber products. The reinforcement principle of carbon fiber cloth is to pre-immerse the highly pull-resistant carbon fiber with epoxy resin into a composite reinforced material (one-way continuous fiber), and to paste the epoxy binder along the pulled direction or perpendicular to the crack direction to form a new complex, so that the reinforced paste material and the original reinforced concrete joint force increase the structure's crack resistance or shear resistance, improve the strength, stiffness, cracking and extension of the structure.
according
China Coatings Onlineexperts, carbon fiber is organic fiber by carbonization and graphite treatment of microcrystalline graphite material. Its microstructure is similar to artificial graphite, and it is a layered graphite structure. Carbon fiber is a new material with excellent mechanical properties, its proportion is less than 1/4 of the steel, carbon fiber resin composite anti-pull strength is generally above 3500Mpa, is 7 to 9 times the steel, pull-resistant elastic module of 23000 to 43000Mpa is also higher than steel. Caben carbon fiber cloth and carbon fiberboard are carbon fiber as raw materials, through a series of production processes to produce carbon fiber products. Their resynamic properties are higher than those of carbon fiber and are the main materials currently used in building reinforcement.
advantages of kaben carbon fiber cloth reinforcement technology: self-weight light, small thickness, reinforcement basically does not increase the thickness of the base; Good flexibility, suitable for beams, columns, plates, pipes and walls and other shapes of components; Resistance to acid, alkali, chemical corrosion, applicable to a variety of different environments; The construction is convenient and the cycle is short. No pollution, in line with the requirements of green environmental protection; Storage life is long, quality assurance period is long. Caben carbon fiber reinforced construction process: construction preparation→ concrete surface treatment→ preparation and painting of substrate →flat→ paste carbon fiber cloth→ surface protection. Caben carbon fiber cloth applications: bending and shearing of concrete beams, bend reinforcement of plates, earthquake-resistant reinforcement of columns, reinforcement of plants, buildings, school buildings, hospitals and other industrial and civil buildings, reinforcement of infrastructure such as road bridges, water conservancy, nuclear power and energy.
