product description:
Polyvinyl alcohol fiber (PVAF) is an ideal environment-friendly cement reinforcement material successfully developed by our company recently. Because of its unique molecular structure, it has good affinity with cement, and has good alkali resistance and weather resistance. Effectively prevent and inhibit the formation and development of cracks, improve the bending strength, impact strength and cracking strength of concrete, and improve the impermeability, impact resistance and earthquake resistance of concrete. It can be widely used in walls, roofs, floors and roads, bridges, tunnels and slope reinforcement of industrial and civil buildings.
At present, in the field of cement concrete engineering, due to the unique properties of PVA fiber, it has broad development prospects in engineering and construction applications. It is an ideal new product that can completely replace asbestos.
performance:
1. High strength and low elongation: superior mechanical properties.
2. Acidity and alkalinity: In a long-term acid-base environment, the strength loss is low.
3. Corrosion resistance: The fiber will not be moldy, rotten or moth-eaten if it is buried underground for a long time.
4. Dispersion: The fiber does not stick together, has good water dispersibility, and has good affinity with cement.
Function:
1.Anti-crack and anti-seepage: The fibers are randomly distributed in the concrete (mortar), which can effectively prevent the occurrence and development of cracks and improve the ability of waterproof and anti-seepage.
2.Anti-shock and anti-seismic: effectively absorb impact energy and improve anti-seismic ability.
3.Improved frost resistance and fatigue resistance.
4.Increase toughness: improve the brittleness of alkali, improve impact resistance and bending resistance.
Applications:
1. Large-volume concrete pouring and guardrails, dams, parking lots, etc.
2. Make concrete components, plates, light wall panels, etc., to replace asbestos and make asbestos cement products.
3. Shotcrete for tunnels, mines, culverts, etc.
4. Make light wall panels, GRC boards, insulation boards and other building materials.
Instructions:
1. The original proportion of concrete remains unchanged, and the fiber is accurately weighed according to the designed addition amount and the amount of concrete mixed each time.
2. After the gravel material is ready, add the fiber, then add the aggregate together with the fiber to the mixer, add water and stir.
3. After the mixing is completed, take random samples. If the fibers have been evenly dispersed into monofilaments, the concrete can be put into use. If there are still bundles of fibers, prolong the mixing time for 30-60 seconds, and then it can be used.
4. The construction and maintenance process of fiber-added concrete is exactly the same as that of ordinary concrete.
5. Product dosage: Generally speaking, for plain slurry or mortar and fiber-reinforced cement slabs and corrugated tiles, the dosage range is 0.6-1kg/m3; the usual dosage is 0.6 kg/m3; for concrete, the dosage range is 0.6-1.9 kg /m3, the usual amount is 0.9 kg/m3.
