In recent years, with the development of research and application of concrete fiber, the of fiber cement board has also been continuously developed, especially the micro fiber represented by polyvinyl alcohol fiber, polypropylene fiber and polyacrylonitrile fiber is more and more widely used in fiber cement. Fiber reinforced cement board belongs to a new generation of "green" "Building materials have the basic function of excellent moisture-proof and fire-proof performance. Fiber reinforced cement board is a new building material produced by taking siliceous and calcareous materials as the main base materials, cellulose fiber reinforced materials and other auxiliary materials and high-pressure curing. It has the advantages of light weight, high strength, anti-corrosion, fire prevention, large format, good processability and improving construction efficiency Point. It is widely used in civil and industrial buildings. It can be used in building floors, inner wall panels, outer wall panels, ceiling panels, curtain wall lining panels, composite wall panels, insulating materials, roof laying, etc.
It cannot be used directly in the construction process. For example, when making wall panels, it needs to be plastered and painted or the bathroom needs to be pasted with bricks. The external wall should not be painted with external wall paint. Now the fiber-reinforced cement board can be sprayed with inorganic fluorocarbon paint on the external surface and decorated on the surface of the fiber-reinforced cement board. It can be directly used as the decorative surface of the internal wall or external wall when leaving the factory.
Fiber reinforced cement board can be glued into a whole through benzene board to form an integrated board for external wall thermal insulation. This board is directly used in the external wall thermal insulation system and has become a new type of energy-saving board. Now many factories begin to produce this kind of thermal insulation board; fiber reinforced cement board can also be installed into aluminum board and become sound-absorbing composite board after perforation. This kind of board is the sound insulation of fiber-reinforced cement board The advantages of good performance are mostly used for the sound-absorbing walls on both sides of the high-speed railway. At present, many units are producing this new material.
