Detail OPU POLYURETHANE FOAM Grouthing Machine
Polyurethane Grouting Material (OPU) 1 pel 10kg. Polyurethane Grouting Material (oil-soluble) is a new type of grouting material used for concrete crack patching, grouting and blocking of water leakage, curtain anti-seepage, reinforcement and strengthening in civil engineering projects, hydraulic and hydroelectricity projects, transportation projects, underground projects including water pools, dam bases, tunnels, mines solid formed by the new grouting material is high-strength and waterproof, thus conveniently used for projects which demand both surface reinforcement and waterproof functions.
. Product Characteristics
1. High expansion, no contraction and excellent waterproof features.
2. High strength, used for both dry cracks and wet cracks. The solid generated by reaction with water can squeeze the water out to realize the waterproof, reinforcement and strengthening functions.
3. Investment is limited due to simple grouting equipment and techniques.
. Technical Index: National Industry Standards Project = WPU Index
1 Density(g/cm3) = 1.05
2 Viscosity(mpa.s) = 1000
3 Gel time(/s) = 850
4 nonvolatile matter content /% = 78
5 foaming capacity /% = 1000
. Construction Technology
1. Check carefully the leakage parts clear the dirt around the cracks for grouting.
2. Hole Arrangement: cut grouting holes at cracks, cut slant holes for deep cracks to cross the quilt top. Commonly 0.2-0.5 meter space between each hole and one half of the concrete thickness as the depth of the holes.
3. Crack Sealing: put in grouting nozzle and seal the cracks with jet cement.
4. Grouting: set the grouting pressure and amount according to the specific crack conditions. When slurry can be seen in the neighboring hole, move to it, grout at the named pressure till the finishing grouting standards.
