Ways to solve the problem of high temperature oxidation of refractory

We know that under normal circumstances, most of the furnace refractories magnesium oxide (MgO) and alumina (Al2O3) refractory oxide-based ceramics. These include refractory oxide ceramic periclase (MgO), spinel (MgAl2O4), corundum (?-Al2O3), mullite (Al6Si2O13), zirconium oxide (ZrO2), carbon (C) and composite materials. When working properly kiln temperature can reach 1400 ?, at such a high temperature furnace refractories in high temperature flame grill, refractory insulation bricks, insulation materials such as cotton insulation extremely high temperature oxidative aging, materials made of crisp , thermal insulation effect is reduced, a sharp decline in the furnace safety index.

Such furnace refractories 3--5 furnace refractories to be replaced a number of years, and the resulting waste material, reducing furnace uptime. Brushing these furnace refractories Dong Tieying Fengtai District Wei Sheng Zhi Hua Chemical Co., ZS-1021 high temperature closed coatings, this coating high temperature, using Chi Sheng Wei Hua specially designed high-temperature solution, the temperature can reach 1800 ?, can grow barbecue time refractory materials using nano-scale sheet structure, good compactness, effectively prevent the diffusion of oxygen at high temperature, the solution of the oxidizing gas contacts the base material, good oxidation resistance, coating hardness can reach 7-8H, harder than hardness of the metal. Coating can be formed on various furnace refractories dense coatings, with strong rust and corrosion, anti-oxidation, anti-discoloration, wear-resistant properties.

High temperature paint brush on a closed furnace refractories, prevents oxidation at high temperatures can reach over 80%, saving material utilization rate can reach 90%, industrial production of high-temperature material safety accident rate may be reduced by more than 95%.
