Factory direct sales of high-strength polypropylene fiber concrete engineering tensile fiber engineering polypropylene fiber

Polypropylene anti cracking fiber is a type of anti cracking modified polypropylene fiber produced by adding modified masterbatch to polypropylene spinning and processing it through special processes and equipment. This fiber has undergone special anti-static and UV resistant treatment, and can be evenly dispersed in mortar. Its "trilobal" cross-section increases the surface area of the fiber, and the surface is treated with special degreasing and drying modification, making it rough and porous, greatly improving the bonding strength between the fiber and cement-based aggregate materials.

2、 Principle of Action

Suppress cracks caused by plastic shrinkage and temperature shrinkage of mortar/concrete, control and reduce the number and size of cracks, and improve impermeability and frost resistance; Increase the toughness of the matrix and the erosion and wear resistance of mortar/concrete; When the mortar/concrete structure is subjected to high temperatures, the fibers melt to form numerous capillary channels, which facilitate the export of water vapor and heat from the internal structure and prevent it from bursting. Meanwhile, as a good temperature compensation method, it can effectively improve its temperature variation performance; Dedicated anti crack fiber utilizes its unique trilobal surface, excellent dispersibility, and cement crystal interweaving structure to improve the cohesion and water retention capacity of the mixture, eliminate the layering and segregation that are prone to occur during transportation and pouring, and cause voids, bees, and other phenomena after vibration. Prevent the decrease of impermeability and frost resistance caused by bleeding.

3、 Product Advantages

Good dispersibility, high gripping force, random distribution, secondary reinforcement, physical reinforcement, crack resistance, anti magnetic and rust prevention, anti-corrosion, alkali resistance, non-toxic and odorless, high safety, easy construction, and economic reliability.

b) Cement mortar: plastering for interior, exterior walls, ceilings, floors, etc.

c) Mass concrete

d) Load bearing plane structure: apron, parking lot, tennis court, etc.

e) Concrete prefabricated components: prefabricated slabs, plates, pipe grids, etc.

2. Water conservancy engineering: shotcrete support, repair, tunnel, slope, subway, spillway, dam panel, dock, etc.

3. Road and Bridge Engineering: Toll stations, expansion joints, airports, runways, bridge deck pavement, bridge bodies, etc. for advanced highways.

5、 Construction process

1. Suggested dosage: Add 0.6-0.9 kilograms of fiber per cubic meter of mortar/concrete.

2. Mixing time: To produce fiber/concrete, the mixing time should be appropriately increased by 30-60 seconds compared to ordinary mortar/concrete, and commercial concrete should be used

Soil does not require an extension of time. mixing

3. Operation procedure: add fibers to the water, add aggregates (stone or sand, etc.), add cement, and add water
