The invention discloses a method for manufacturing a microcrystalline glass water-quenched material by adopting an amorphous graphite ore surrounding rock spontaneous combustion method. Amorphous graphite ore surrounding rock is taken as a main raw material, and defined amounts of glass powder, calcite, borax, basic magnesium carbonate and soda ash are added, so that chemical composition of a finished product meets requirements of a CaO-Al2O3-SiO2 ternary system phase diagram; and the content of graphite carbon meets the requirement that materials are melted at high temperature, and the content of graphite carbon generally accounts for 12-18%. The method disclosed by the invention comprises the following technological steps of: firstly mixing and grinding the materials into 200-mesh uniform powder, adding water into the powder, moulding and drying, then feeding the dried material into a high-temperature kiln, introducing the air or oxygen, warming to the temperature of being about 1500 DEG C by utilizing combustion of graphite carbon to melt the material, carrying out water quenching on molten fluid with running water, drying the water-quenched material, and then crushing the water-quenched material to a certain granularity as required, so that the microcrystalline glass water-quenched material is obtained. The microcrystalline glass water-quenched material can be made into microcrystalline glass and microcrystalline foam glass with excellent performance and wide application range by carrying out secondary burdening and sintering.
Description
technical field [0001] The invention relates to the technical field of new building materials, in particular to a method for producing water-quenched glass-ceramics by spontaneous combustion of surrounding rocks of earthy graphite ore. Background technique [0002] Glass-ceramic water-quenching material is an urgently needed product in the market, and its manufacturing process requires more fuel. Glass-ceramics has a high density, corrosion resistance, wear resistance, non-conductivity, non-magnetic conductivity, high strength, and can be made into plates with smooth surfaces, etc., and has a very wide range of uses. Microcrystalline foam glass is a new type of multifunctional material, which can be used for load-bearing walls of buildings, low-temperature pipeline containers and equipment, chemical and petrochemical equipment, heat exchange and sound insulation walls, etc. [0003] The manufacture of glass-ceramics and foam glass-ceramics is generally completed in two s...
