Polypropylene mesh fiber
Introduction polypropylene mesh fiber
Polypropylene mesh fibers, also known as reticular fibers, reticular fibers, polypropylene fiber network, which is based on modified polypropylene as raw material, extrusion, drawing, into a network of surface modification, Short processes processing. The appearance of multi-fiber filament fibers cross each other even from the network structure. When the reticular fibers into the concrete, the reticular fibers are squeezed one by one, ripped into two hook-shaped filament and pull each other more to the distribution deduction, increased fiber and concrete adhesion. Showed a large number of fibers in the concrete three-dimensional distribution, to provide network supporting role, fundamentally changing the concrete cracking, impact resistance, fatigue resistance, wear resistance, greatly improving the toughness and deformation of concrete, thus greatly improving the concrete works quality. As a new type of concrete reinforcing fibers, polypropylene fiber mesh fiber reinforced concrete scientific research is becoming a new hot spot applications.
Performance of polypropylene mesh fiber

Mechanism of polypropylene fiber mesh
In the curing process of concrete, causing shrinkage of concrete, and because in the latter part of the water evaporation caused by concrete shrinkage, the shrinkage stress exceeds the tensile strength of a cement will cause microfractures. Policy of cracks in the gel are mostly done at this time tensile strength of concrete is very small. After the addition of fiber in the concrete, fiber can be uniformly distributed in the concrete in the rapid formation of a three-dimensional chaos to the support system, the directional spread of the concrete stress crack resistance wire concrete occurrence of the native and the development of micro-cracks to eliminate or reduce the number and length of the ability to greatly enhance the permeability of concrete to enhance toughness, thus extending the service life of concrete.
Features:
Improve the impermeability of concrete
Improve the ability of concrete cracking
To improve the impact resistance of concrete and the resistance to fatigue
To improve the wear resistance of concrete
Improve the plastic deformation of concrete
Strong acid and alkali resistance, good stability.
Polypropylene mesh fiber Application:
The polypropylene mesh fibers greatly improve the performance of concrete, so most of the concrete can be applied to polypropylene mesh fibers, the main can be applied:
1, concrete pavement, bridge, airport runway;
2, mine walls, roof, tunneling;
3, dam, seawall, pier revetment, reservoir, etc.;
4, industrial and civil buildings;
Polypropylene mesh fiber is the "constant solid," a series of fiber products, which is made of polypropylene resin, made by special processing and handling of bundles of fibers interwoven into a network, it has a very strong and concrete base affinity, after mixing, the result of the impact of sand by the cement, auto open, forming a root mesh monofilament or another involves the random distribution of fibers to reduce plastic shrinkage cracking of concrete early split-level and stress level, which greatly improve the concrete cracking, permeability, impact resistance, increased toughness and wear resistance of concrete.
Polypropylene mesh fiber technology parameters: MX1 HG strength of a polypropylene mesh fiber Size: 6mm 9mm 12mm Weight: 0.91g/cm3 Tensile strength: 529Mpa The initial elastic modulus: 4479Mpa Acid alkaline: strong Elongation: 26.4% Moisture content: <0.2% Melting point: 163 ℃ Security: Non-toxic Packing: 0.9kg / bag. 19.8kg / package (based on customer requirements) Polypropylene mesh fiber product features: Compared with steel fiber, polypropylene fiber mesh obtained in the fully dispersed polypropylene monofilament with a fine degree and number of significant advantages, combined with polypropylene fibers themselves of available moisture is low, strong alkali acid and the elastic modulus and other properties of concrete rather, to improve its performance and the role of concrete in the following points are particularly prominent. First, to improve the crack resistance of concrete. Second, improve the impermeability of concrete. Third, improve the wear resistance of concrete. Fourth, to improve the impact resistance of concrete and the resistance to fatigue. Fifth, to improve the bending and bending properties of concrete. Sixth, improve the internal protection of concrete reinforcement capability. VII, especially the high-strength concrete to improve concrete plastic deformation. Eight strong acid, has good durability.
Polypropylene mesh fiber applications: First, the concrete pavement, bridge, airport runway, the ground station for high crack resistance and other projects, depending on the dosage could extend the life of the project 5-10 years. Second, the tunnel, the mine's walls, roof, reservoirs and other projects with special construction methods, the use of injection technology of concrete construction, can reduce the spring rate, reduce pipeline disruption, the spring rate of the concrete wall no more than 8%, the vault does not exceed 12%, greatly improving the efficiency of construction and improve the working environment. Third, the diversion canal dams and other projects, the addition of fiber to effectively improve the crack resistance of concrete, seepage, abrasion resistance, extending the life of the project. Fourth, pier, deep water docks, shore protection, military protection works.
