摘要
A method for the formation of resin-bonded grit slabs is described, in which a mixture containing inert minerals, and liquid resin in the minimum quantity necessary to bind the inert materials together, in order to avoid any excess of binder and thus to reduce the coefficient of thermal expansion of the finished product to levels compatible with its use, is subjected to combined pressure and vibration, in an airless environment, to obtain porosity-free slabs. The apparatus comprises a conveyor belt for automatically transferring the material, consisting of grit and resin mix in the quantity provided by a dispenser and held between two continuous sheets of cardboard under a vacuum vibratory press in which a slab is formed, and means for transporting the formed material into a drying oven in which the process is completed, with rapid polymerization of the resins, to produce grey slabs.
