摘要 |
The invention relates to a method for making quick ageing abrasive slurries particularly designed for the construction of grinding wheels, comprising the steps of preparing a slurry starting from magnesium carbonate, magnesium sulphate, abrasive materials and inert fillers, adding a phenolic resin, kneading to obtain a homogeneous mass, filling the slurry in forming molds and carrying out an ageing step, by cyclically heating the slurry with set increasing temperatures, and a subsequent cooling to the environment temperature.
