Embodiment 1

[0024] Select 54% of waste ceramic fragments with 19% alumina content and 62% silica content, 12% dolomite, 6% limestone, and 28% pottery clay, add 0.4% SiC micropowder, crush and mix, ball mill for 24 hours, press filter, and dry , granulation, centrifugal rotation into balls, dried and fired at 1170°C to make a bulk density of 0.5kg / m 3 ceramic floating beads.

Embodiment 2

[0026] Select 20% of waste slag with 14% alumina content and 71% silica content, 30% silt, 20% tremolite, 4% limestone, and 26% clay, crush and mix, ball mill for 20 hours, dry granulate, dry press After forming, it is fired at 1160°C, and then cold processed to make a flat product of 800×800×30mm. After experiments, the finished product has a bulk density of 0.6kg / m 3 , Flexural strength 6.5Mpa, in -20 ℃ ~ water freeze-thaw for 3 hours, 5 cycles, no damage, it proves its excellent frost resistance.

Embodiment 3

[0028] Select 30% of waste ceramic fragments (glazed) with 19% alumina content and 70% silica content, 25% waste slag, 15% tremolite, 6% dolomite, and 24% pottery clay, crush and mix, and ball mill for 18 hours , After pressure filtration, vacuum mud refining and extrusion molding, it is fired in a shuttle kiln at 1150 ℃, and then cold processed to make cylindrical products of Φ100×200mm. After experiments, the finished product has a bulk density of 0.6kg / m 3 , Flexural strength 6Mpa, in -20 ℃ ~ water freeze-thaw for 3 hours, 5 cycles, no damage, it proves its excellent frost resistance.

Abstract

Belonging to structural ceramics materials field, the invention relates to a light, adiabatic, soundproof and green ceramic. Its chemical composition and weight percentage are as follows: SiO 45-78 percent, Al2O3 12-26 percent, CaO+MgO 4-15 percent, Fe2O3 0-8 percent, LiO2+K2O+Na2O 1-8 percent and etc. Its method follows nether steps: evenly stirring waste sludge or (and) waster slag or (and) waste ceramic scatters of 50-80 percent, blending of primary mineral with expending performance of 20-50 percent and agglutinant of 0.1-2 percent, crash blending to ball mill for 16-24 hours, moulding and drying, burning in 1100-1250deg.C, cold working and finally getting fullbodied glass phase, even close micro pores and completely sintered light ceramic. Merits of the invention lie in that effectively use industrial discards, production has an excellent physical performance, sintering performance is very good, float on water surface for a long time without sinking and cracking and freezeproof performance is very good.

Description

technical field [0001] The invention relates to a ceramic product, in particular to an environment-friendly ceramic product. At the same time, the invention also relates to a manufacturing process of the ceramic product, which belongs to the technical field of structural ceramic materials. Background technique [0002] For environmental protection, reducing the pollution of industrial waste and strengthening the recycling of industrial waste is the theme of sustainable development of my country's environmental protection. In recent years, many enterprises have tried their best to strengthen the recycling and development of industrial waste. How to comprehensively utilize industrial waste to further serve environmental protection and reduce waste pollution, noise pollution, water pollution, and heat pollution has become an urgent need for environmental protection, and it is also a development project supported by the state. The search found that the Chinese invention patent...
