Definitions
- This invention relates to loads of raw materials for preparing glass and, more specifically, to a method for preparing pre-reacted loads of raw materials for the production of glass formulas, to which cullet is added (recycling glassware) in order to increase the speed of calcination processing, the degree of decarbonation of the charge and the formation of the desired crystalline structures.
- cullet is added (recycling glassware) in order to increase the speed of calcination processing, the degree of decarbonation of the charge and the formation of the desired crystalline structures.
- the charge for preparing molten glass has been, for many years, to feed independent components for glass, typically silica, sodium carbonate, calcium carbonate, borates, feldspar, dolomite, kaolin, etc., in proportions that go according to the desired glass formulation, to a smelting furnace at temperatures ranging from 1400 to 1600 ° C.
- independent components for glass typically silica, sodium carbonate, calcium carbonate, borates, feldspar, dolomite, kaolin, etc.
- These typical charges include raw materials that have different melting points and react at different temperatures under different operating conditions.
- US Patent No. 4,920,080 of Demarsest describes a method for pre-heating and pre-reacting all portions of the load before the melting stage, in two separate portions, a first portion of SiO 2 with Na 2 CO 3 in a first pre-reaction zone, for a time and at a temperature sufficient to form a product consisting predominantly of sodium silicate, and heating a second portion of SiO 2 with CaCO 3 in a second pre-reaction zone for a while a temperature sufficient to leave calcium free of carbonates. It can be concluded that, from the methods discussed in the aforementioned patents, efforts have been made to provide pre-reacted raw materials in which the gaseous components have been advantageously eliminated.
- . consists of a molecular formula comprising a number of molecules of Si, Na, Ca, Mg, Bo, etc., which can be clearly approximated from natural substances, partially treated minerals, or intermediate products of treated minerals, which they include molecular systems of Si-Na, Si-Na-Ca, Si-Na-Mg, Si-Ca-Mg, Si-Na-Ca-Mg and mixtures thereof, some of which are in the form of pre substances -reacted and some of which have to be conveniently pre-reacted in a calcination furnace and, in any case, these are free of gaseous carbon dioxide.
- phase diagrams are prepared for different molecular systems of raw materials, it is possible to select molecular formulas that have decomposition and / or melting temperatures well above at least 1000 ° C, below which not only molten glass or liquid phase is not formed, but the release of carbon dioxide can also be clearly carried out, which are selected from invariant points or points on a line connecting invariant points of phase diagrams of said molecular systems, and combine them to reach or approximate the molecular formula of the desired glass, completing it by pure silica when necessary.
- phase diagrams can be found in the publications of KA Shahid & FP Glosser "Phase equilibria ⁇ n the glass forming region of the system Na 2 O-CaO-MgO- SiO 2 " (Phase equilibrium in the glass forming region of the Na 2 O-CaO-MgO-SiO 2 system ) published in Physics and Chemistry of Glasses Vol. 13 No. 2 April 1972; and by GW Morey and NL Bowen, "Corner of system Na 2 O-CaO-SiO 2 " (Corner of the Na 2 system O-CaO-SiO 2 ) published by Soc. Glass Technol., 9pp. 232, 233 (1925).
- Figures 1 to 8 are diagrams of residence time against oven temperature and CO 2 content of the tests carried out with the following molecular systems: Na-Ca-5Si; Na-Ca-5Si (foundry silica); Na-Mg-4Si; Na-Mg-4Si (foundry silica); Na-3Ca-6Si; Na-3Ca-6Si (foundry silica); Na-3Ca-6Si (foundry silica); and Na-2Ca-3Si. DETAILED DESCRIPTION OF THE INVENTION.
- the method for preparing pre-reacted loads of raw materials, with low carbon dioxide content, for the production of glass formulas, of the present invention comprises: mixing stoichiometric amounts of selected substances of natural minerals , partially treated minerals or intermediate products thereof, which contain molecular systems of silica-sodium, silica-sodium-calcium, silica-sodium-magnesium, silica-calcium-magnesium, silica-sodium-calcium-magnesium and mixtures thereof , which have reaction temperatures and of release of C0 2 , below 1000 ° C, which do not form a liquid phase at such temperatures; which are selected from invariant points or points on a line that connects invariant points of phase diagrams of said molecular systems, to complete or approximate a desired glass formula; add selected amounts of cullet to the load; and calcine the load to obtain the pre-reacted loads of raw materials, for use in glass formulas.
- the prepared mixture is subjected to agglomeration, forming briquettes, which are subsequently subjected to calcination.
