1、 Brief Introduction of Water Soluble Polymer Chemical Grouting Plugging
High pressure grouting plugging is to use the mechanical high pressure power (high pressure grouting machine) to inject water soluble polymer chemical grouting materials into the concrete cracks. When the grout encounters the water in the concrete cracks, it will quickly disperse, emulsify, expand, and consolidate. This consolidated elastomer fills all the cracks in the concrete, and completely blocks the water flow outside the concrete structure, To achieve the purpose of water stop and leakage stoppage. High pressure grouting plugging technology is a new waterproof technology of high-pressure airless grouting with international advanced level, which is a new technology used in water-soluble grouting materials in developed countries.
2、 High pressure grouting plugging principle:
Water soluble polymer chemical grouting material is a kind of polymer cutting flexible elastic material, which is composed of several molecular materials of polymer chemical agricultural production system, and is proportioned according to strict proportioning standards.
Commonly used multi polymer materials include propylene, crystal and gel. Polyhydroxy compounds are polyethers, which can have several functional groups and molecular weights. After the grout is poured into the concrete crack, it will meet with the leakage water to produce chemical reaction, release carbon dioxide, and form macromolecular organisms. So as to achieve the purpose of seepage prevention and plugging.
Water soluble polymer chemical grouting material is a kind of bottom viscosity, one component synthetic polymer flexible elastic material in the form of flexible elastomer. It has the characteristics of cross-linking reaction when encountering water, and foaming to form a multi-element network closed elastomer. When it is injected into the concrete crack structure under high pressure to extend until all the cracks (including those that are hard to detect by the naked eye) are filled, when it meets with water (water injection), it is accompanied by cross-linking reaction, releasing a large amount of carbon dioxide gas, generating secondary seepage pressure. High pressure thrust and secondary seepage pressure will press the elastomer into and fill all the cracks,
To achieve the purpose of leak stop It can be seen that the water soluble polymer chemical grouting material is one of the plugging materials with good performance. The leakage cannot be treated with ordinary materials. After the high-pressure grouting plugging technology is used, the leakage is successfully plugged at one time.

Technical characteristics of high-pressure grouting 1. Brief introduction to new technology of high-pressure grouting waterproof and leak stopping
High pressure grouting plugging is to use the high pressure power of machinery to make water soluble polyurethane When the chemical grouting material is injected into the concrete crack, when the grout encounters the water in the concrete crack, it will quickly disperse, emulsify, expand, and consolidate. This consolidated elastomer fills all the cracks in the concrete, and completely blocks the water flow outside the concrete structure, so as to achieve the purpose of water stop and leakage stoppage. High pressure grouting plugging technology is a new waterproof technology of high-pressure airless grouting with international advanced level, which is a new technology used in water-soluble grouting materials in developed countries.
2. High pressure grouting plugging principle:
Water soluble polyurethane chemical grouting material is oligomeric carbamate prepolymer containing free isocyanate group, which is prepared from excessive polyisocyanate and polyhydroxy compounds. Common polyisocyanates include TDI, MDI and PA PI Etc. Polyhydroxy compounds are polyethers, which can have several functional groups and molecular weights. After the grout is poured into the concrete crack, it will meet with the leakage water to produce chemical reaction, release carbon dioxide, and form urea derivatives. So as to achieve the purpose of seepage prevention and plugging.
Water soluble polyurethane chemical grouting material is a kind of bottom viscosity, one component synthetic polymer polyurethane material, in the form of slurry, which has the characteristics of cross-linking reaction when encountering water, and foaming to form a multi-element network closed elastomer.

High pressure thrust and secondary seepage pressure will press the elastomer into and fill all the cracks, so as to achieve the purpose of leakage prevention It can be seen that the water soluble polyurethane chemical grouting material is one of the plugging materials with better performance.
