The meaning of Malisan
- Malisan is a polyimide gel material with low viscosity. When water blocking is carried out, the resin and catalyst are mixed together and react or expand when exposed to water, react or foam to form a multi-element network dense elastomer. When it is pushed by high pressure and injected into the coal rock layer or concrete cracks (under the action of high pressure, the closed cracks in the coal rock layer can be opened), it can be extended along the coal rock layer or concrete cracks until all cracks (including cracks and cracks that are difficult to detect with the naked eye) are Filling of cracks that reopen under high pressure). When sealing cracks and strengthening coal strata, when the coal stratum does not contain water, the expansion rate of the product will be correspondingly smaller (the expansion multiple is
.
. ~
.
. times). The high-pressure thrust will Malisan is pressed into and fills all gaps to stop leakage.

. The amount of grouting for each hole is determined according to the grouting pressure. During construction, the grouting pressure must be strictly controlled. When the grouting pressure reaches
