In recent years, continued to trek polypropylene fiber technology has been widely broadened focus and malls fiber industry. This article describes the development trend concise polypropylene fiber technology, and on the localization path melt spun nonwovens equipment, short spinning equipment, technical characteristics BCF and monofilament production equipment and related equipment were analyzed polypropylene and comments. Through years of research and engineering experience in the use of polypropylene fibers were more mortar concrete projects waiting. Polypropylene fibers in the mortar to reduce and prevent the use of shorter cracks appearance, prevent and reduce shrinkage cracks after hardening concrete work, the temperature cracks, etc. After pouring concrete curing time of the early causes of bleeding, which greatly improved durable function products. Polypropylene fiber is mainly used for concrete panels, concrete and other parts of the primary impact mill serve to reduce drying shrinkage crack and impact grinding function trek to intent. Because polypropylene fibers other highly viscous function, which is used in sprayed concrete projects, improved function and decreased shotcrete springback.

 
Followed by practitioners on the use of polypropylene fibers in the project approval, the continuous improvement in the way to deepen practitioners know the product function together, polypropylene fiber mortar concrete products will become more widespread use. Characteristics of polypropylene fiber: 1, polypropylene fiber has a strong effect crack resistance; 2, a great journey of concrete durability; 3, trek concrete impact resistance and patience. Polypropylene fiber in terms of the use of hydraulic engineering: the use of high-speed assembly line site. Some of the main powerhouse underwater plate used in construction of mixed use your map. Used in spray concrete. What are the implications of polypropylene fibers have an impact on the mechanical function ppf hardened concrete to concrete mechanical function, depends on many aspects, such as the incorporation of species ppf: such as shape (bundles, monofilament mesh; aspect ratio, etc. etc.) and physical properties of the size and content. From here, the primary shape (monofilament and wispy; aspect ratio) and the content of the size of the angle of impact tests by the incorporation of research discourse ppf previous mechanical function of hardened concrete. Personally think, ppf function for concrete improvements in the primary reflected in the tensile crack resistance, then trek the concrete impermeability and other durable function, after the trek all the concrete execution service function. Polypropylene fiber in 1960 by the Italian company Montecatini prime industrial production is completed, the mid-1980s, polypropylene fiber production has crossed international 1Mt, have produced more than 40 countries. Er, the Daqing Refining & Chemical Company polypropylene plant has produced a series of high-melting means self HP565S polypropylene fiber material has been completed industrial production.
