An introduction of High strength & modulus PVA fiber
High Strength & Modulus PVA Fiber is a kind of High tensile strength, High young's modulus, High alkali resistance of synthetic fiber, the fiber is small density, diameter, many performance is better than the other synthetic fibers, at the same time of cement, gypsum and so on base material with a strong affinity.
We only need in base material such as cement, gypsum to 0.3% ~ 0.5% of the High Strength & Modulus PVA Fiber and a small amount of polymer, we can effectively change base material such as cement, gypsum, brittleness, eliminate the base material of cracks in the process of hydration. As a result of the existence of fiber consumed energy and relieve the stress, prevent the further development of crack, have played an important role in blocking cracks, so in the cement, gypsum products, mixed with a small amount of High Strength & Modulus PVA Fiber, can be achieved:
1, improve the tensile strength of substrate.
2, block matrix defects existing crack extension, and delay the emergence of new cracks, improve the water resistance, permeability resistance, frost resistance.
3, improve the ability of deformation of the matrix, thus to improve its toughness and impact resistance.
