High Strength and high modulus PVA fiber

Product Overview:

High-strength and high-modulus PVA fiber has high tensile strength and modulus. Its properties such as acid and alkali resistance, anti-aging, corrosion resistance, ultraviolet resistance are harmless to human body and environment. Therefore, it is an ideal substitute for industrial asbestos and is widely used in high-performance concrete engineering and special fields such as coinage and military.

Properties:

1. Good mechanical and physical properties: High-strength and high-modulus PVA fibers have high tensile strength and modulus and low elongation. Its tensile strength is comparable to steel bars. The elastic modulus matches the elastic modulus of concrete, which can improve the early tensile strength of concrete, and can also Improve the tensile strength of concrete in the middle and late stages, which greatly save construction and maintenance time and shorten the construction period.

2. High affinity with cement: High-strength and high-modulus PVA fiber has good affinity with cement, and its bonding strength is higher than that of nylon 6, polypropylene, polyester and other fibers. Due to its special molecular structure, PVA fiber has good adhesion to the interface of brittle material-cement, and plays a reinforcing role.

3. Good dispersion: The high-strength and high-modulus PVA fibers do not stick to each other and disperse well in water. The fibers are uniformly dispersed in concrete, distributed randomly, and overlapped with each other to form a three-dimensional network structure. It improves the brittleness of concrete, increases its toughness, and improves its crack resistance, impermeability, frost resistance and impact resistance, thereby improving the overall quality and the durability of concrete.

4. Good alkali resistance and weather resistance: High-strength and high-modulus PVA fiber has good chemical stability. After being mixed into concrete, it will not react chemically with any material in the concrete. Acid and alkali resistance and chemical resistance are better than other fibers such as rayon, nylon 6, and polyester.

5. Good light resistance and corrosion resistance: High-strength and high-modulus PVA fiber has a much lower fiber strength loss rate than other fibers under long-term sunlight. The fiber is without mold, corrosion, or moth even buried underground for a long time .

6.Environmental protection and no pollution: High-strength and high-modulus PVA fibers do not generate dust and inhale into human lungs during transportation and using, and will not decompose toxic gases when encountering high temperatures, so they are harmless to humans and the environment.
