Polyester fibers following the application of polypropylene fibers in mortar, cement concrete, only in recent years developed a new engineering material, mainly used for the enhancement of asphalt concrete crack prevention function, it is also known as asphalt fibers or asphalt concrete dedicated fiber 
 Detailed description of crack king of polyester fiber 
 Crack king (KLW-003), polyester fiber, "Karen Yueda Building Materials Co., Ltd. 100% polyester raw material, the use of advanced production equipment and high-tech science and technology research and development by a dedicated asphalt concrete high-tech engineering fibers. "Crack king (KLW-003), the polyester fiber is polyester (poly benzene, dimethyl glycol ester, PES) as the main raw material, through the plasticized melt extrusion, high-speed spinning, high-magnification stretching a special surface treatment process, and use a special cutter to cut off from the appearance of multiple single fibers, the color was white. Hang Yueda crack king (KLW-003) polyester fiber "because of ignition and melting point in the high temperature of the asphalt concrete, will not change their physical properties because the heat will not be oxidized in under the conditions of 260 ° C for 2 hours, the volume did not change, and still maintain good tensile properties, it plays a significant tensile role in the asphalt concrete. 
 Physical parameters of the polyester fiber 
 Fiber type single color white (natural color) 
 Tensile strength of ≥ 15-25% elongation at break 900 the MP a 
 Acid and strong elastic modulus 13.50Gpa 
 Equivalent diameter 20-30um length 3-19mm (can be customized) 
 The proportion of 1.36-1.38 kg/m3, melting point 240-260 ℃ 
 Crack king of polyester fiber applications 
 1 concrete rigid self-waterproof structure, basement floor, side walls, roof and roof floor, pool, etc.; 
 ② cement mortar, dry mortar, insulation mortar, cracking mortar, interior and exterior plastering mortar, etc.; 
 ③. Crack resistance, impact resistance, abrasion resistance, earthquake and other requirements of the occasion; 
 ④. Deck, piers, ports, water conservancy and other. 
 Crack king of polyester fiber construction process 
 Asphalt crack control content is 1.36-1.38 kg/m3, crack king (KLW-003), polyester fiber, (specifically require the use of design drawings), mixing the required amount of fiber added to the mixer, the first and the aggregate dry mix for 30 seconds, then add the wet asphalt mix for 30 seconds. For the continuous roll-hole mixer in batches for distribution of mixing equipment, mixing process is different. Continuous roll the mixer of the hole, the fiber must join together with the aggregate in the aggregate is completely dry before; batches for distribution to stir the equipment directly in the mixing process according to project ratio fibers join aggregates stir.
