摘要
Waterglass solutions are mixed with polyisocyanates and these emulsions are then left to harden in the formations. Introduction of the mixture into the formations which are required to be consolidated, e.g. deposits of coal, is mainly carried out by forcing the mixture under pressure into bore-holes in the formations. According to one variation of the process, the components of the mixture are introduced into the multi- chamber cartridges which are introduced into the bore-holes and then destroyed as the components are mixed. Certain additives such as accelerators, blowing agents, polyols, stabilizers and/or thixotropic agents are advantageous for the quality of the composite masses formed by hardening of the mixture.
