PVA Concrete Fibers Reinforcement concrete
Material: 100% Polyvinyl alcohol
PVA Fibers
Polyvinyl alcohol fiber (PVA fiber for short) is a synthetic concrete fiber made of high polymerization of high quality polyvinyl alcohol (PVA) and processed with specific advanced technology.
Characteristics of PVA fiber
1. has very good mechanical properties, its high strength, high modulus, low elongation.
2. acid and alkali resistance, chemical resistance.
3. light resistance: under long time sunlight, the fiber strength loss rate is low.
4. corrosion resistance: fiber buried in the ground for a long time without mold, rot, insects.
5. fiber has good dispersion: fiber does not stick, good dispersion in water.
6. fiber has good affinity with cement, plastic, etc. and high bonding strength.
7. Non-toxic and harmless to human body and environment.

Applications of PVA concrete fibers
1. Polyvinyl acetal fibers are used in industry to make canvas, tarpaulin, filter cloth, transportation belts, packaging materials, work clothes, fishing nets and cables for marine operations.
2. High-strength, high-modulus filaments can be used as skeleton materials for transportation belts, lining materials for all kinds of hoses, tapes and shoes, as well as making bicycle tire cord.
3. Since this fiber can resist the alkalinity of cement and has good bonding and affinity with cement, it can replace asbestos as the reinforcing material of cement products. It can be widely used in cement products, road construction, water conservancy projects, etc.
4. It can be blended with cotton to make all kinds of clothing and interior products, and can also produce knitted products. However, the heat resistance is poor, and the fabric made is not stiff, and cannot be washed in hot water.
5. In addition, it is also used in non-woven fabrics, paper making, etc.

Production process of polyvinyl alcohol fiber
PVA fiber raw materials used polyvinyl alcohol average molecular weight of 60,000 ~ 150,000, thermal decomposition temperature of 200 ~ 220 ℃, the melting point of 225 ~ 230 ℃. PVA concrete fiber can be made by wet spinning and dry spinning. The heat treatment of polyvinyl alcohol fiber by acetalization treatment can be obtained polyvinyl alcohol acetal fiber. The acetalization process is to remove the mannitol (sodium sulfate) by washing, from the aldehyde solution (by the aldehyde agent formaldehyde, diluent water, catalyst sulfuric acid, swelling inhibitor sodium sulfate composition) through, and then by washing process. The tow can also be cut into short fibers and conveyed by airflow to a post-treatment machine for acetalization on a stainless steel screen. In order to improve the fiber properties, can contain cross-linking agent boric acid polyvinyl alcohol solution (concentration of 16%) for wet spinning, the resulting primary fiber in the alkaline coagulation bath solidification, after neutralization, washing and multi-stage high tensile and heat treatment, then you can obtain the strength of 106 ~ 115cN / dtex filament.
