he slightest introduction
Polyacrylonitrile fiber as a secondary reinforced concrete material can significantly improve the toughness and impact resistance of concrete, and effectively prevent the emergence and development of cracks, improve the impermeability of concrete, frost resistance and other durability. In addition, as an industrial fiber for reinforced asphalt concrete, it can not only improve the adhesion of asphalt pavement, high temperature stability, fatigue durability, and has a low temperature cracking and to prevent the performance of reflective cracks. Effectively improve the tensile, shear, compression and impact strength. Its great role in the concrete and the use of the prospects have been more and more recognized and accepted by the engineering community.
Here we say that the advantages of polyacrylonitrile fiber, making it with the concrete between the irreversible link!
Advantages 1: good dispersion
Polypropylene nitrile molecules containing polar nitrile (CN), so that the fiber has good hydrophilicity, so in the normal mixing time, tough 2005 fiber in the cement mortar and concrete can be dispersed very uniform. The
Advantages two: grip strong binding
The toughness of the 2005 fiber section is cashew-shaped, with a larger cross-section with a cement-based material greater contact area, and the surface by a special rough treatment, making tough 2005 fiber and cement-based materials have a good grip The
Advantages of three: the number of fiber roots
Polyacrylonitrile fibers with a length of 6 mm are 1.1 billion kilograms per kilogram.
Advantages of four: light resistance, good weather resistance
Polyacrylonitrile fiber is the best fiber in all natural and synthetic fibers except for fluorine-containing fibers to ensure good long-term effectiveness of the fiber.
