Alkali Resistance Roving can resist corrosion of high alkaline substances,which are produced by cement hydrates.And it has excellent anti-acid,anti-alkali performences,and high tensile strength.
Features:
Alkali resistance:Soaked 4 hours in CaOH2 saturated solution(100 ¡æ),strength retention rate> 90%;Soaked 1 hour in 10% NaOH(100%),weight reduction rate (excluding sizing) <0.5%
Monofilament coated alkali resistance layer,can effectively resist the erosion of basic material on the fiber
Durability: up to 50-100 years
Temperature: softening point 860 ¡æ
Modulus: 72 - 80.4GPa
Specific weight:2.7
Elongation: 2.4%
Tensile strength: 1800MPa, 2-3 times that of steel fiber
