Abstract

The invention relates to a rapid plugging agent. The rapid plugging agent is mainly composed of hemihydrate gypsum, magnetized six barium ferrite, cement, a promoter, a plasticizer, a curing agent, etc. The rapid plugging agent has characteristics of rapid plugging speed, high activity, good plugging property and chemical stability, good rheological performance and uniform compressive strength ratio.

Description

technical field [0001] The invention relates to a rapid plugging agent, which belongs to the technical field of fine chemical preparations. Background technique [0002] With the continuous development of urban underground buildings, civil air defense projects and large-scale sewage pipe network construction, due to geological reasons, construction technology, and construction material problems, leakage, channeling, edge water, bottom water intrusion, Contradictions and problems such as premature water discharge, water flooding, and collapse have gradually emerged, which have seriously affected the entire construction progress and project quality. Therefore, the research and application of various types of plugging agents have increasingly received great attention from various research institutions. At present, a number of chemical plugging technologies have been developed in the market, such as high-strength chemical water plugging of sodium silicate, polymer water plugging...
