A PROCESS FOR OBTAINING AGENTS FOR FIRE-INHIBITING IMPREGNATION OF POROUS MATERIALS AND DEPTH FIRE EXTINCTION OF THE SO-CALLED SMOULDER FIRES ON PEAT LAND, IN COAL AND COMMUNAL WASTE DEPOTS

摘要

This invention belong to the field of chemistry and relates to PROCESS FOR OBTAINING AGENTS FOR HRE-INHIB ITING IMPREGNATION OF POROUS MATERIALS AND DEPTH HRE EXTINCTION OF THE SO-CALLED SMOULDER FIRES ON PEATLAND, IN COAL AND COMMUNAL WASTE DEPOTS. The invention concerned resolves a technical problem whereby a mixture is obtained which, through a special process, performs fire protective impregnation of wood and wood products, packaging corrugated cardboard, textile of natural materials and other hard porous materials. It can also be effectively applied for subsurface extinction of smoulder fires in peat land, coal and communal waste depots. This has been achieved so that the mixture is composed of anhydrous magnesium chloride (MgCl2) and the wetting agent diluted in water in precisely specified weight proportions that are later subject to impregnation. After this, there is an instant covering of the treated matter with a hygroscopic layer that has fire-fighting properties and acts as a retardant.
