摘要： The present invention relates to a two-compartment cartridge which is suitable for securing stay bars in bore holes by means of polyurethane resins and which is destructible by the stay bar, containing a polyisocyanate component on the one hand and a polyol component on the other hand, distinguished by the fact that the polyisocyanate component used is an aromatic polyisocyanate or a mixture of aromatic polyisocyanates, while the polyol component used is a polyol containing tertiary amine nitrogen and having a molecular weight of from about 119 to 3000 or a polyol mixture containing at least one such polyol. The present invention also relates to a process for securing stay bars in bore holes by introducing into the bore hole a two-compartment cartridge which contains components capable of forming a synthetic resin and which is destructible by driving in the stay bar and subsequently driving in the stay bar, distinguished by the fact that a cartridge of the type described above is used as the two-compartment cartridge.

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.

摘要： For consolidation of geological formations and artificial beds of rock, earth, and coal by means of foaming and hardening polyisocyanate/polyol blends, diols with secondary hydroxyl functions of the OH number range 150-1000 are used as diol component. Preferably a crude polyisocyanate blend (MDI) obtained by phosgenation of aniline/formaldehyde condensates which at ambient temperature assumes a liquid state, and the liquid prepolymers of said crude MDI are used as isocyanate components.
