Introduction of Polypropylene Mesh Fiber

Polypropylene mesh fiber is made of polypropylene as raw material through a special process. Its appearance is a mesh structure formed by multiple fiber monofilaments interlaced with each other. When the polypropylene mesh fiber is put into concrete, during the concrete mixing process, the transverse connection between the fiber monofilaments is dispersed by the rubbing and friction of the concrete itself, forming a fully opened fiber monofilament or mesh structure, thereby achieving the effect of a large number of polypropylene fiber concrete. As a new type of concrete reinforcing fiber, polypropylene mesh fiber is becoming a new hot spot in the scientific research and application of fiber concrete after steel fiber and polypropylene monofilament fiber.

Product Function of Polypropylene Mesh Fiber

Improve the impermeability and wear resistance of concrete; improve the reinforcement capacity of concrete; improve the crack resistance of concrete; fire resistance; improve the impact and fatigue resistance of concrete; improve the bending tensile strength and flexural strength of concrete; improve the plastic deformation capacity of concrete, especially high-strength concrete; extremely strong acid and alkali resistance, with good durability.

Application of Field Polypropylene Mesh Fiber

1. Projects with high crack resistance requirements such as concrete pavement, bridge deck, airport pavement, factory floor, etc.

2. Engineering projects that use special construction methods such as walls, roofs, and reservoirs of tunnels and mines. When using the spraying process for concrete construction, adding fibers will effectively reduce the rebound rate of the sprayed concrete and reduce pipe friction.

3. Rivers, dams, and other projects.

4. Military protection projects, dock revetments, bridge piers, etc.

Usage of Polypropylene Mesh Fiber

Recommended dosage: 1-2kg/m3, concrete with special requirements can be increased to 5kg/m3.

Mixing process: add aggregate → add fiber → add cement → add water → stir → add water to disperse all the fibers.

FAQs About Polypropylene Mesh Fiber

1. What is Polypropylene Mesh Fiber?
   • Answer: Polypropylene mesh fiber is a synthetic fiber made from polypropylene, a thermoplastic polymer. It is commonly used in construction and industrial applications due to its high strength-to-weight ratio, durability, and resistance to chemicals and moisture.
2. What are the main uses of Polypropylene Mesh Fiber?
   • Answer: Polypropylene mesh fibers are primarily used to reinforce concrete, improving its tensile strength and reducing the risk of cracking. They are also used in geotextiles, erosion control mats, and as a component in various composite materials.
3. Why is Polypropylene Mesh Fiber preferred over other materials?
   • Answer: Polypropylene mesh fiber is favored for its lightweight nature, excellent chemical resistance, and ability to withstand harsh environmental conditions. It is also cost-effective and easy to handle compared to other reinforcement materials like steel.
4. How does Polypropylene Mesh Fiber improve concrete?
   • Answer: When added to concrete, polypropylene mesh fibers help to distribute stress more evenly throughout the mixture, thereby enhancing its overall strength and durability. They are particularly effective in reducing micro-cracking, which can lead to structural weaknesses over time.
5. Is Polypropylene Mesh Fiber environmentally friendly?
   • Answer: Polypropylene mesh fiber is considered relatively environmentally friendly because it is made from a recyclable material and has a long lifespan, reducing the need for frequent replacements. However, proper disposal and recycling practices should be followed to minimize environmental impact.
