Background
The polypropylene monofilament is a high-strength polypropylene bundle-shaped monofilament fiber, and the excellent dispersibility of the fiber in concrete and the bonding force with a cement machine body are ensured through a special surface treatment technology. It is generally used for fine aggregate concrete. The concrete fiber (the concrete is recommended to use the special fiber for the concrete with 12-19mm and has high strength and good anti-crack effect.) the tensile strength is more than 500mpa, the elongation at break is 15-25%, the elastic modulus is more than 3800mp, and 1, and the anti-crack capability of mortar and concrete is effectively improved. Experiments prove that: compared with the common mortar/concrete, if monofilament fiber with the volume mixing amount of 0.1 percent (about 0.9Kg/m3) is added, the crack resistance of the mortar/concrete is improved by 70 percent. 2. Greatly improving the impermeability of the concrete. The anti-permeability of the polypropylene bundle monofilament fiber concrete with the addition of 0.9Kg/m3 is improved by 60 to 70 percent compared with the common concrete. 3. The impact resistance and the wear resistance of the concrete are obviously improved. Although the polypropylene fiber has lower rigidity and poor load transfer capability, the polypropylene fiber can absorb impact energy, effectively reduce cracks, enhance the continuity of a medium material and reduce the local stress concentration phenomenon caused by blocking of shock waves, thereby greatly improving the impact resistance and toughness of concrete. 4. The frost resistance of the concrete is improved. The polypropylene fiber is added into the concrete, so that the effect of internal stress of the concrete caused by temperature change can be relieved, and the expansion of temperature cracks is prevented; meanwhile, the improvement of the impermeability of the concrete is also beneficial to the improvement of the frost resistance of the concrete. Practice and research show that the polypropylene fiber added into concrete can be used as an effective concrete temperature difference compensation anti-cracking means. 5. The quality of the concrete product is improved, the integrity of the edge, the corner and the surface of the product is effectively maintained, and the reinforcing steel bars in the product are not corroded.
Need dry it after the polypropylene monofilament preparation, general stoving mode can not carry out good stoving to it, still can make its fracture because of the influence of air turbulent flow at the in-process of drying moreover, and the whole efficiency of drying is not high moreover, and cost loss is bigger moreover.
