Product Description

Hydrophilic polyurethane foam agent epoxy PU double component material for concrete crack repair

QY DM-11 hydrophobic polyurethane foaming agent, is a water-activated (hydro-active) water cut-off grout.Upon contact with water, DM-11 hydrophobic polyurethane foaming agent generates carbon dioxide and react immediately to a hard foam,expanding its volume 25 to 30 times and then expand rapidly to fill with cracks.The cured material is essentially not effected by water. The reacted material does not shrink or swell. Effective in stopping the water leakage, can stagnate water as well as reinforce.

Hydrophilic Polyurethane Foaming Agent is a single component hydrophobic water cut-off grout and soil stabilization grout based on a MDI (Methylene Diphenyldiisocyanate) polyurethane. The cured material is semi flexible and of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell.

Hydrophilic polyurethane

Qian-Yu DM-I hydrophilic polyurethane slurry injection is a kind of high-molecular chemical injection material, generating from the reaction between hydrophilic polyether polyol and isocyanate. After meeting with water, it will set off a chemical reaction and generate elastic colloidal solid, which fills all the gaps to reach the purpose of waterproofing.

Construction joint leaking

1 Drill the hole at the left or right 5CM-10CM at the lowest point of the construction joint to one-half of the thickness of the structure, and drill from the low to the high in the order. The hole distance is 20CM-30CM, and it is better to drill to the highest point and then bury it again. Water needle.

2 After the setting of the grouting water stop needle is completed, the chemical grouting material is injected into the high pressure perfusion machine until the grouting liquid is found to ooze out on the surface of the structure body. 3 After the filling is completed, the grouting and water stopping needle can be removed.

Honeycomb leaking

1 At the hive range, drill a hole every 25CM-30CM, the depth is one-half of the thickness of the structure, and then fill the grouting needle and tighten it.

2 After the water stop needle is set, the chemical grouting material is injected into the high pressure filling machine until the grouting liquid is found to ooze out on the surface of the structure, so that the water leakage problem can be solved. 3 After 48 hours of filling, the grouting needle can be removed.

Precautions for grouting machines

1 The connection between the machine includes: high pressure pipe and switch group, the connection between the high pressure pipe and the machine needs to be wrapped with raw tape.

2 The screw parts of the machine also need to be tightened to prevent the machine from falling apart or missing parts during high-pressure operation, including machine glue and handles.

3 The motor and the machine need to be placed in place without leaving a gap. Next, let's talk about a few important issues in the process of use.

4 Since the material injected by the machine cannot be in contact with water, the machine is strictly prohibited from washing with water.

5 machine maintenance is the key to cleaning (after washing with thinner, it is best to use vegetable oil or oil again, usually sold in hardware stores)

6 The last and most important problem is the safety of life. The machine belongs to high-pressure machinery. When the pressure is too high, it is necessary to stop the injection at the right time to prevent harm to yourself.
