PVA Fiber Use For Reinforced Concrete, Glass
1、Superior Mechanical And Physical Properties
HSHM PVA fiber has high tensile strength and modulus, low elongation. The tensile strength is not inferior much to steel bar and elastic modulus can match with concrete’s. It can improve the early strength of concrete, but also the tensile strength of concrete in the late, can greatly save construction curing time, shorten construction cycle.
2、High Affinity With Cement
HSHM PVA fiber has good affinity properties with cement and the bonding strength is better than that of nylon 6, Polypropylene, polyester fiber etc. Because of the unique molecular structure, PVA fiber plays the reinforcing function on the interface bonding with brittle material cement.
3、good dispersion
HSHM PVA fiber is not adhesive between each other and can disperse well in water. Fiber in the concrete evenly disperses, randomly distributes then overlaps into a three-dimensional network.
PVA fiber (Polyvinyl Alcohol fiber)
CAS No: 9002-89-5
Molecular formula:(C2H4O)n
Molecular weight:44.05
Cut length: 3-50mm
PVA-Fiber is mainly used in sheet and section material, and could prevent the microcrack caused by plastic shrinkage of the concrete. This environmental product gradually takes place of the asbestos and becomes a new kind of material.
The Main Parameters of PVA Fiber:
Count： 2.0±0.25dtex
Tenacity： ≥11.5CN/dtex
Elongation： ≤7.5%
Molulus（0.1-0.4%）： 280±20 CN/dtex
Hot Water Solubility(90℃,1hour）： ≤2%
Cut Length： 5mm, 6mm,12mm or filament
The Performance of PVA Fiber
PVA-Fiber has high tensile strength and an excellent mechanical property
1.High performance of ACID & alkali resistance and a low damage in the long-time environment of acid & alkali
2.Good light and season resistance. In the long-time sunshine, has a lower damage than other fibers
3.Good dispersivity. The fibers are separated and easier to disperse when come to the water.
4.Good affinity with the cement
The Function of PVA Fiber
1.Anti-crack and anti-infiltration:The fibers distribute in the mortar and concrete in different directions, which can prevent the happen and development of the crack.
2.Anti-impact and anti-quake: Absorb the impact power and improve the anti-impact capacity
3.Anti-frost and anti-fatigue: Relieve the stress caused by the temperature difference and increase the anti-frost and anti-fatigue capacity
4.Anti-rub: Decrease the dusting,flaking,weathering of the concrete roads
5.Increase toughness: Improve brittleness of the concrete and increase the anti-break capacity
6.Weight reduction: Increase the anti-stretch and anti-cut capacity of the concrete, so the cross section size of the ready-made sections are decreased, therefore decrease the weight of itself.
The Application of PVA Fiber
1.Take place of asbestos and manufacture the asbestos cement products.
2.Make the light wallboard,insulation board and other building material.
3.Make the component of the concrete,tubing and board.
4.Large acreage concrete pouring, such as quay.
5.The roof,basement of the industrial and residential building.
6.The sprayed concrete, such as tunnel,mine,culvert and side slope.
