The function and introduction of polypropylene engineering fiber!
Introduction to polypropylene engineering fiber:
Polypropylene engineering impermeable short fiber is the use of fiber grade polypropylene as raw material, through special processing and forming of high-strength bunch monofilament organic fiber, its inherent resistance to strong acid, strong alkali, weak thermal conductivity, with extremely stable chemical properties. The addition of mortar or concrete can effectively control the micro-cracks caused by temperature changes and other factors in the initial plastic shrinkage stage of mortar and concrete, prevent and inhibit the formation and development of cracks, greatly improve the crack resistance and impermeability of concrete, impact resistance and earthquake resistance, and can be widely used in underground engineering waterproof. Roofing, walls, floors, pools, basements, roads and Bridges of industrial and civil construction projects. It is a new ideal material for crack resistance, seepage prevention and wear resistance of mortar and concrete engineering.
Functions of polypropylene engineering fiber:
As a secondary reinforcement material of concrete, high polypropylene fiber can greatly improve its cracking resistance, impermeability, impact resistance, earthquake resistance, frost resistance, impact resistance, burst resistance, aging resistance and workability, pumpability, water retention.
1. Prevent cracks in concrete.
2. Improve the permeability resistance of concrete.
3. Improve the freeze-thaw resistance of concrete.
4. Improve the impact resistance, bending resistance, fatigue resistance and seismic performance of concrete.
5. Improve the durability and anti-aging of concrete.
6. Improve the fire resistance of concrete.
