Polypropylene fiber PROPERTIES 1. with the rapid development of domestic economy and urban construction and enlarged scale of industrial and civil construction, the requirement to the technical disposal of building surfaces is much higher than before . 2. on the basis of improving body's engineering design and constructing quality. 3. Improving the surface quality, like roof of building and wall and floor, becomes a crucial task to the construction field. So on the basis of successfully developing polypropylene fiber-mesh for concrete and polyester fiber for bitumen and in view of some technical problems existing in constructing field, we sums up experiences and develops cracking-resistance reinforced fiber for cement paint (using in plastering). This fiber can improve quality of building's wall and floor, and supply a new technical measure to reduce the surface crack, so it has a good economic value. APPLICATIONS: 1. function: Resist to shrink & crack Increase seepage resistance Increase friction resistance Increase freezing & thawing resistance Improve tendons protection Replace steel net (using in plastering) Prevent mortar split and crackle expansion Increase impact resistance and peeling resistance 2. The Feature of Polypropylene Monofilament: A). No agglomeration and easily spread around in mortar or concrete. Guarantee the property of crack resistance effectively B). Apply conveniently. No need to change the proportion of mortar, and just put the fibers into the mortar mixture and stir for a moment after adding water. C). Has fine economic property. The equivalent dia. of polypropylene monofilament is only φ 0.02mm, so the ratio of dia. And surface is high and on the basis of crack resistance, it can reduce the amount (0.6kg/m 3 ) and cut down the cost effectively. D). Be better to plaster. Because a great number of thin fibers spread into mortar evenly, so the plastering is much easier and this can improve the binding strength between surface and base. E). The fiber has stable chemical property, strong acid &alkali resistance, and can be used in any engineering projects. 3. Suitable Engineering for Polypropylene Monofilament A). Be suitable for the waterproof layer, floor, inner &outer wall of industrial and civil construction. B). Increase cracking resistance on the surface of industrial workshop, warehouse and parking lot. C). Increase cracking & seepage resistance of the ground in natatorium, swimming pool, pond and ditch. D). Be suitable for any mortar projects and fine aggregate concrete projects. 4. Applying Instruction A). Compound Amount. To resist the common cracks on surfaces, 0.6kg/m3 fibers to cement paint are enough, and for reinforced application 0.9-1kg/m3 are enough. B). Stirring requirement. The proportion of cement, sand and aggregate is no need to be changed. Put cement, aggregate, additive and fiber together, then stir after adding enough water (Do not stir without water!) and time for stirring can be prolonged for 2 3 minutes in order to make the compound mix completely. 5. brief specification: Raw Material 100% virgin Polypropylene Crack Elongation 15-20% Fiber Type monofilament Fiber Dia. 0.02±0.005mm Melting Point 160 170 c degreeDensity(g/cm3)0.91Acid &Alkali Resistance StrongTensile Strength(MPa) 7.67cN/dtexPACKING: normal packing is 0.6kgs or 0.9kgs per plastic bag, and 10 or 20 bags in a carton.
