For polyurea grouting material, the construction needs to adjust the foaming speed. Polyurea grouting material
Commodity characteristics of polyurea grouting material: It uses water as a reagent, polymerizes after mixing with water, and foams, expands, and solidifies into a low shrinkage, compact gel with repeated foaming performance with water. It is a traditional plugging material for plugging. Polyurea grouting material is suitable for plugging projects such as simple loose structure, low flow seepage, intermittent leakage or secondary stable grouting.
Introduction to polyurea grouting materials : polymerize with water, disperse and emulsify, and expand to form a porous structure foam with high foaming rate, block its structural cracks and tightly bond with the base material, so as to achieve leak stoppage. After the action of polyurea grouting material and water, the crack will be quickly expanded and blocked, so as to stop the water and increase the structure; It also uses low amount of catalyst, and adjusts the foaming speed according to the practical construction needs, so as to achieve the function of leak stopping.
Storage and transportation of polyurea grouting material : Wear protective equipment (such as gloves and eye protection) during construction to avoid direct contact with skin. If contaminated, wash with plenty of water. Polyurea grouting material This product is a solvent based material. Pay attention to wind and keep away from fire sources during construction. Open fire shall not be used around the construction area before the materials are solidified. The machine shall be cleaned with detergent after use. Store in a dry and cool place. Collision, direct sunlight, rain, fireworks are not allowed during transportation.
Fenyangtang brand polyurea grouting material has good hydrophilicity and will undergo polymerization reaction after encountering water, disperse emulsification or foam expansion, and sand The soil is consolidated into a consolidated body to block cracks and stop water. The induction time can be controlled, and the consolidation time of the product after encountering water can be controlled in tens of seconds and several minutes.
Construction method of polyurea grouting material : Carry out grouting, determine the grouting pressure and grouting amount according to the specific situation of the leakage part, inject the crack with high-pressure grouting machine materials, when pure grout appears in the adjacent hole, move the adjacent hole until the specified pressure grouting cannot be pressed, and then close it immediately valve 。 The polyurea grouting material shall be inspected at the later stage. After 72 hours, observe whether there is leakage at the leaking part. If there is no leakage, break the grouting water stop needle and use quick drying method cement Seal and smooth the base surface to complete plugging.
