With high strength and high modulus PVA fiber is also called the PVA fiber, fiber whalen.Because of the high strength, about 11.5 cn/dtex, far higher than that of high-strength polyester fiber and high-strength nylon, and has a high elastic modulus.
A, quality indicators

Second, the performance
1, high strength low stretch: superior mechanical properties
2, acid, alkali, acid and alkali environment for a long time, low strength loss.
3, dispersion: fiber not adhesion, good dispersibility, under the influence of water and cement affinity is better.
Three, functionality,
Percolating-proof: 1, the fiber to distribution in concrete (mortar), effectively prevent the occurrence and development of cracks, improve the ability of waterproof impermeability.
2, impact resistant earthquake: effectively absorb the impact energy, improve the aseismic ability.
3, frost resistance, fatigue resistance, link stress caused by temperature difference, improve the ability of frost resistance, fatigue resistance.
4, anti-wear, can reduce the surface of concrete road surface of the dust, peeling, weathering.
5, increase resilience: improve the brittleness of concrete, improve the shock resistance and bending capacity.
6, weight loss, improve the concrete tensile shear strength, therefore, can reduce casting or casting body section size, thereby reducing their weight.
Four, the main thoroughfare
1, the mass concrete casting, such as terminal, high-rise building conversion beam, column, floor and so on.
2, industrial and civil building roof, basement, wall plaster mortar processing.
3, roads, Bridges, roads and barriers.
4, DAMS, concrete pouring, pools, parking lots, stadium, etc.
5, make concrete member, tubes, plates.
6, tunnels, mines, tunnels, slope surface sprayed concrete, etc.
7 zone, coastal tidal flats, and alkali, chemical corrosion.
8, replace asbestos, asbestos cement products.
9, a light-weight wall panels, GRC board, insulation board and other building materials.
Five, the characteristics of
1, non-toxic harmless, safe and reliable, and construction personnel do not cause harm to the environment.
2, good affinity with cement, strong grip of.
3, good dispersion, no adhesion, easy to spread.
4, construction simple, cost-effective.
Six, using the method
1, according to the design of the addition amount and the volume of each mixing, accurate weighing fiber;
2, after the application of ready, adding fiber, and then add the aggregate along with fiber mixer, water mixing (also can be spread fiber stir in the water first and then from the mixer to join mixed with aggregate).
3, after the completion of the mixing random sampling, such as fiber has evenly dispersed into monofilament, criterion of concrete can be put into use, if you still have bunch of fiber is extended mixing time 30 to 60 seconds, can be used.
4, add fiber concrete with normal concrete construction and maintenance process is exactly the same.
5, in general, dosage of product and pigment paste or mortar and fiber reinforced cement plate, wave tile, range of 0.6 - for the amount of 1 kg/m3, often amount to 0.6 kg/m3;For the amount of concrete, and range of 0.6-1.9 kg/m3 often dosage of 0.9 kg/m3.
Seven, use matters needing attention
1, adding fiber, concrete than the same original ones.
2, adding fiber, still must be strictly in accordance with relevant state regulations construction and maintenance.
3, skin allergies, should try to avoid direct contact with the skin.The skin such as mild discomfort, please wash with water.
4, this product is non-toxic, the proportion of 1.3 g/cm3, melting point 216 ℃ above, so when using high safety.
