| titleOfInvention | Modified sand for dyeing and its production method |
| abstract | Modified sand for dyeing, especially for dyeing sand for colored thin-layer mosaic plasters, is characterized by the fact that at least part of the surface of the sand grains is etched and has patterns and micropores to increase the size of the surface of the sand grains in relation to the size of the grains of natural sand, and at least part of the surface of the sand grains is covered permanently with a layer of hardened crystalline water glass. The method for producing modified dyeing sand is to wash and dry the sand. Before the drying operation (9), water glass is introduced and dosed into moist sand and mixed with moist sand in a continuous process, after which, in the operation of flame drying of sand, crystallization and curing of the water glass coating on sand grains occurs. Preferably, dust is emitted in the sand drying operation. After drying, sand is fractionated depending on the size of its grain. 2 to 6 kg of water glass are used for one ton of sand, depending on the fraction of its grains. Sodium or potassium water glass or a mixture of about 95% by weight sodium water glass are used as water glass. with potassium water glass in an amount of about 5% by weight The invention is used to refine sands intended especially for dyeing, to be used as a component of colored plasters applied on foam insulation of buildings. |
