Polyurethane Grouting Fluid

Single Component Hydrophilic Polyurethane Grouting fluid is a kind of polymer chemistry grouting material, which is made of hydrophilic polyether polyols and Isocyanate. The material reacts with water to form an elastic colloidal solid, thus achieving a good water-stopping effect. It is a new high-pressure grouting material for water-proof and leak-stopping.

This product is produced by our company through the introduction of advanced foreign technology. Polyurethane grouting material is a kind of high elasticity and toughness gel with low shrinkage and compact structure, which is polymerized after mixing with water and then rapidly foamed, expanded and solidified. This product has a very superior self repairing function by repeatedly foaming with water, and its waterproof and leak stopping effect is 2-3 times that of traditional leak stopping materials.

Product Features

—

1) When the slurry meets water, it will undergo chemical reaction immediately and disperse, emulsify and foam by itself to form an impermeable elastic colloidal solid with good water-stopping performance.
2) Quick response, high strength and strong packing.
3) With the aid of the gas pressure, the grout can further press into the voids of the structure, so that the porous structure or the formation can be completely filled and compacted.
4) The slurry has good swelling property, large water inclusion capacity, good hydrophilicity and filling property. And the viscosity of the slurry, curing speed can be adjusted according to needs.

Strengthened hydrophilic polyurethane grouting material, strong toughness, good water wrapped.

Performance

—

Industry standard: JL/T2041-2010

Central control indicators

—

1. Isocyanate content (%) 6.5-7.5
2. Water encapsulation (requires the addition of L4, BT, and Ding before performing water encapsulation)
Type I (15 times water): ≤ 50s Type II (10 times water): ≤ 50s Type III (10 times water): ≤ 50s

All picking indicators

—

Note: When conducting water-based central control, a water inclusion test should be conducted first. If there are abnormal situations such as white spots, translucency, or inability to contain water during the water inclusion process, it is judged as unqualified, and the content of - NCO should be measured at the same time.
