I. Product description of polypropylene fiber for construction

"Siliyuan" brand modified polypropylene fiber is an organic fiber developed by Jiangsu Siliyuan Fiber Co., LTD., which is specially used for construction projects. This product is a cut fiber made by adding polypropylene granule to master material, blending, spinning, winding, drawing and cutting by using special processes such as anti-static and anti-aging. It can effectively improve the binding force of fiber and base material and be applied to mortar/concrete. It can prevent, reduce and delay the early plastic cracking, and improve the comprehensive performance of mortar/concrete.

Two, building polypropylene fiber product parameters and properties

"Filar wire" brand modified polypropylene fiber cross section for three leaf or round, good alkaline resistance, good chemical stability, good dispersion in mortar/concrete, strong grip, each cubic meter of tens of millions of fibers three-dimensional distribution in the concrete, in the concrete plays a pure physical reinforcement role.

Building polypropylene fiber parameters and properties:

◆ Diameter (μm) : 18-50

◆ Length: 3, 6, 9, 12, 16, 18, 20

◆ Fracture strength (MPa): > 400

◆ Density (g/cm3): 0.91

◆ Initial modulus (GPa): >3.5

◆ Elongation at break (%): 15-35

◆ Melting point (°C) : about 160

◆ Ignition point (°C): about 580

◆ Acid resistance: high

◆ Safety: non-toxic, no stimulation

◆ Alkali resistance: high

◆ Thermal conductivity: low

◆ Low temperature resistance: better

Three, building polypropylene fiber effect:

As a secondary reinforcement of concrete, "Sisi silk edge" brand modified polypropylene fiber can improve its cracking resistance, impermeability, impact resistance, earthquake resistance, frost resistance and other properties.

Application: water conservancy and hydropower engineering, cast-in-place concrete and precast components, municipal, highway, bridge, building engineering, industrial production of premixed mortar, etc.
