The way to solve the problem of refractory high temperature oxidation
We know that normally, kiln refractory mostly magnesium oxide (MgO style) and alumina (Al2O3) refractory oxide ceramics. The refractory oxide ceramics include periclase (MgO style) and spinel (MgAl2O4), corundum and mullite (alpha Al2O3) (Al6Si2O13), zirconia (ZrO2), carbon (C) and its composites. Furnace can work normally when temperature reached 1400 ℃, under such a high temperature, furnace refractory material under high temperature flame barbecue, refractory insulation brick, heat preservation cotton thermal insulation materials such as high temperature oxidation ageing, material hair crisp, heat preservation and heat insulation effect, kiln safety index fell sharply.
This kiln refractory kiln refractory material has to be replaced every 3 to 5 years a group, and a waste of materials, reduce furnace normal working hours. These kiln refractory coating fengtai chi ChengWeiHua chemical co., LTD. East rail camp the ZS - 1021 high temperature sealing coating, the coating of high temperature resistant, adopts ChengWeiHua special high temperature solution, heat-resistant up to 1800 ℃, can long refractory barbecue, using nano scales flake structure, good compactness, effectively prevent the diffusion of oxygen at high temperatures, solve the oxidizing gas contact matrix material, good oxidation resistance, the coating hardness can reach 7-8 h, hardness is higher than the hardness of metals. Coating can form a dense coating on the kiln all kinds of refractory materials, with strong rust anti-corrosion, anti-oxidation, prevent discoloration, such as wear-resisting properties.
High temperature resistant coatings, closed on the furnace refractories, prevent high temperature oxidation rate can achieve 80% above, the material utilization rate of energy saving can reach more than 90%, high temperature industrial production material safety accident rate can be decreased more than 95%.
