Polypropylene staple fiber

Polypropylene staple fiber polypropylene staple fiber, non-toxic, odorless, with high chemical stability, chemical resistance, acid hydrolysis resistance, insect resistance, fungal resistance, and good electrical insulation, simplicity in operation , without changing the ratio of concrete. Key polypropylene staple fiber concrete fiber quality is its dispersible fibers, if the dispersion is not good, but just the opposite, easily the formation of voids in the concrete, some of the low prices, poor quality and generally straight wire fiber on the poor dispersibility Please note that customers who choose to use. The company's strength is the staple building works through a special process, with a strong dispersion, the mixing process can be rapid and uniform dispersion of the concrete, please select the trial. Product specifications and technical parameters: Material: Polypropylene Type: bundle monofilament denier (g / 9000m): 15 Length: 3mm, 6mm, 12mm, 19mm, 22mm, 38mm Package: 0.5kg-5kg Note: according to customer different needs, different lengths of fiber products manufactured color: white, non-variegated (not because of the time and yellowing) equivalent diameter: 36um Weight: 0.91 tons / cubic meter water absorption: No, moisture content <0.1% thermal conductivity: Very low conductivity: Insulating material, non-conductive. Flash point: 1100 degrees Fahrenheit (about 580 degrees) Modulus of elasticity: 3793MPa acid and alkali: resistant to acid, alkali, and its performance is not easy with time and aging. Tensile strength: 40,000psi (276MPa) Safety: non-toxic materials, no smell, and its products on humans and the environment without any pollution, harm, is the green building materials. Product Features: polypropylene staple fiber construction projects, with a special production process for surface treatment, with cement-based materials have a strong cohesive force, good will fully Sand / concrete overall performance, improve crack resistance, impermeability tortoise plastic shrinkage, impact, shock, freeze-thaw resistance, abrasion resistance and other properties, and has a good AllEasy, non-sticky, non-segregation, no bleeding, easily dispersed, never change, etc. First, reduce the initial crack, crack resistance as a whole increased by 90%; Second, impermeability water capacity increased by more than 75%; Third, impact: the first visible crack and all broken impact significantly improved after 28 days, impact, seismic capacity increase more than 50%; Fourth, wear resistance increased more than 40%; five, fiber reinforced concrete pavement to extend the useful life of 5--10 years; 6, anti-extrusion: after 28 days compressive strength test, the sample than the average over 4 % in July, anti-freeze: 300 times by repeated freeze-thaw test, 96.2 percent life eight flexural: flexural strength test seven days growth of 1%, 28-day trial increased by 28% in September, added concrete fiber aggregate can be avoided precipitation, prevent burst scope of concrete: First, industrial and civil construction, crack, impermeability mortar plastering, wall paint, putty production; Second, higher cracking impermeability requirements basement, rigid roof, shell and seismic structural concrete; three, bridges, tunnels, airport runways concrete; Fourth, ports, water conservancy, dams, concrete buildings of various brine; V. manufactures various types of cement concrete; such as cement panels, cement pile cement tile, pavement tiles, structural beams (secondary distribution bars) and the like. Six, all the requirements of increased seepage, cracking underground engineering, seawall, pools, dams and other concrete projects. Seven, ordinary roads, highway construction and maintenance, to increase its wear resistance of the load capacity. Eight, alkali resistance and chemical resistance to higher places and special occasions, urged the application of non-magnetic reinforcing material
