Introducción detallada

Polyvinyl Alcohol Fiber (PVA fiber) is an ideal environmentally friendly cement reinforcement material. Because of its unique molecular structure, it has good affinity with cement and has good alkali resistance and weather resistance. It can effectively prevent and inhibit the formation and development of cracks, improve the flexural strength, impact strength and crack resistance of concrete, and improve the impact resistance and earthquake resistance of concrete. It can be widely used in the reinforcement of walls, roofs, floors, roads, bridges, tunnels and slopes of industrial and civil buildings. At present, in the cement concrete engineering industry, 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.

Product Features

1. Compared with other general organic fibers, polyvinyl alcohol fiber has higher toughness and elastic modulus.

2. The bonding strength between fiber and cement matrix is strong. Bond strength can also be controlled through surface treatment.

3. Its good durability has been proven through long-term field testing and it has been used as fiber cement slate for more than two decades as polyvinyl alcohol fiber has gained ground as a less hazardous and affordable alternative widely accepted.

Application areas

1. High strength and high modulus polyvinyl alcohol fiber is an excellent substitute for asbestos fiber and glass fiber.

2. Large-volume concrete pouring and guardrails, fences, parking lots, etc.

3. Make lightweight wall panels, GRC boards, insulation boards and other building materials.

4. High-strength and high-module polyvinyl alcohol fiber fibers can also be used in high-end road construction, airport runways, and factory floors.

5. Shotcrete for tunnels, mines, culverts, etc.

6. Water conservancy and hydropower projects such as docks, river dams, and hydropower stations.

7. Can also be used for plastic reinforcement materials.

Instructions

Product dosage:

1.Plain slurry or mortar and fiber reinforced cement slab, the dosage range is 0.6-1kg/m³

2.The commonly used amount is 0.6kg/m³.

3.For concrete, the dosage range is 0.6-1.9kg/m³, and the common dosage is 0.9kg/m³.

Concrete mixing time: When making fiber mortar/concrete, the mixing time should be appropriately increased by 30-60 seconds. Commercial concrete does not need to be delayed.

Concrete mixing process: add aggregate → add fiber → add cement → add water → stir → add additional water. Just disperse all the fibers.

Packaging and storage

Packaging: Inner plastic bag 0.6kg-2kg per small package, outer woven bag or carton 10kg-25kg per large package. It can also be produced and packaged according to user requirements.
