摘要

Procedure for obtaining a coadjuvant and accelerator product for the cutting and milling of stone materials, consisting essentially of sulphite liquors or "black waters", from the treatment of wood for its conversion into cellulose in the paper industry, whose lyes they are subjected to an evaporation process, using evaporators of single or multiple effect, through which evaporation, which gives rise to the boiling of water and other volatile substances that are eliminated in the form of vapor, is carried out using as a fluid heating the saturated water vapor, resulting in this phase to a very concentrated solution that is extracted from the evaporator and poured into a container of large dimensions in plant and low height, where it cools, then precipitating the product in crystalline form, crystallization which, on the other hand, can also originate in the same evaporator, as a consequence of a saturation d the liquid, followed by a grinding of the dry product obtained, in order to achieve a water-soluble and non-hygroscopic powder, in which, as fundamental components, there are lignin sulphonic acids or their salts, thus leaving the product ready for its use, for which an aqueous solution of said powder is used as cooling liquid of the tools used in the cutting and milling of stone materials in their various natural or artificial classes, such as stones, marbles, granites, ceramics and refractory (Machine-translation by Google Translate, not legally binding)
