Abstract
Base material for the manufacturing of baked vitreous or vitrocrystalline pieces, characterized in that it is a granulated material with granules with a particle size with a diameter smaller than 2,000 μm that comprises, at least, 60% and 99.89% by weight of a first component selected among a frit composition, an enamel composition, glass, or mixtures thereof, 0.1% and 5% by weight of an organic binding agent that has a decomposition temperature lower than the end of sintering temperature of the base material; and in that said material is formed of granules with a humidity content lower than 3% by weight.
Claims33
Base material for manufacturing baked vitreous or vitrocrystalline pieces, wherein said base material is a granulated material with granules of a particle size with a diameter smaller than 2,000 μm that comprises, at least,
- 60% and 99.89% by weight of a first component selected among a frit composition, an enamel composition, glass or mixtures thereof,
- 0.1% and 5% by weight of an organic binding agent that has a decomposition temperature lower than the end of sintering temperature of the base material;
- and
- said base material is in the form of granules with a humidity content lower than 3% by weight.
Process for the preparation of a base material used for the manufacture of vitreous or vitrocrystalline pieces, comprising:
- a first step in which a first mixture is prepared by mixing, at least, a first component selected from among a frit composition, an enamel composition, glass, or mixtures of any of them with, at least, an organic binding agent selected from among the above-specified binding agents, and wet grinding same until a particle size with a diameter smaller than 1,000 μm is obtained, and
- a second step in which a granulated material with granules of a diameter smaller than 2,000 μm that comprises 60% to 99.89% by weight of the first component and 0.1 to 5% by weight of the organic binding agent is obtained, subjecting the first mixture to granulation and drying to a humidity content lower than 3% by weight.
