Problems solved by technology

[0002] The kilns used to produce daily-use ceramics and sanitary ceramics are all old-fashioned kilns fired with coal or oil as fuel, and relatively heavy refractory saggers or roasting plates are used to load ceramics. This production method consumes a lot of energy and waste gas emissions. Large scale and serious environmental pollution. With the continuous innovation of modern ceramic production kilns, the original refractory saggers or roasting plates are far from meeting the needs of current ceramic production. Therefore, we have successfully produced a A high temperature resistant, energy saving silicon carbide plate

Abstract

The invention discloses a high-temperature-resistant energy-saving silicon carbide plate and a preparation method thereof, belonging to the technical field of ceramic materials. The high-temperature-resistant energy-saving silicon carbide plate is prepared from the following components in percentage by weight: 20-40% of 3.0-1.0mm SiC particle, 10-205 of 1.0-0.5mm SiC particle, 5-15% of 0.5-0.088mm SiC particle, 15-25% of 0.088-0.003mm SiC fine powder, 5-10% of 0.003-0mm SiC micropowder, 5-10% of 0.088-0mm silicon micropowder, 1-5% of composite binder, 0.5-1.0% of composite antioxidant and 1-7% of water. The preparation method comprises the following steps: proportionally mixing the materials, forming, drying, firing, and spraying a high-temperature oxidation-resistant paint on the surface. The high-temperature-resistant silicon carbide plate has the advantages of high density, high compressive strength and folding strength, consumption reduction, energy saving, lower waste gas emission and waste reutilization.
