Problems solved by technology

However, the surface coatings commonly used in China currently have limited wind speed resistance, about 30 m / s. When such surface coatings are used in passivation furnaces and AP furnaces, because the wind speed reaches 60 m / s, they are still Easy to be blown loose and cause loss of insulation layer
In this regard, some customers use refractory bricks to replace surface coatings, but because the price of refractory bricks is 2-3 times that of surface coatings, it cannot generally solve the above problems at low cost

Abstract

The invention discloses a high-wind speed resistance capacity wear-resistant fiber surface coating. The high-wind speed resistance capacity wear-resistant fiber surface coating is characterized by mainly comprising the following raw materials in percentage by mass: 15 to 20 percent of alumina particles with the particle diameter of 4 to 20 mu m, 50 to 60 percent of mullite particles with the particle diameter of 0.1 to 1mm, 25 to 35 percent of aluminum sol with the content of 5 to 10 percent, and 0.2 to 0.5 percent of adhesive. By improving a process and a formula, the wind speed resistance capacity of the surface coating is improved to 60 meters / second, and the surface coating can be cured when being dried at the temperature of 105 DEG C; and the high-wind speed resistance capacity wear-resistant fiber surface coating is greatly superior to common surface coatings, and the performance of the high-wind speed resistance capacity wear-resistant fiber surface coating is greatly improved.

Description

technical field [0001] The invention relates to the field of refractory fiber production, in particular to a high-wind-speed and wear-resistant fiber surface coating. Background technique [0002] At present, in the application of refractory materials in various domestic kilns, ceramic fiber blocks are widely used as refractory insulation layers. Ceramic fibers have special and excellent properties, such as small shrinkage, low thermal conductivity, and good thermal insulation performance. However, in the special environment of high wind speed (60 m / s), such as in some kilns with high wind speed, because the texture of the ceramic fiber itself is relatively soft, the surface fibers will be blown away by the high wind speed. As a result, the environment in the furnace deteriorates. On the one hand, the insulation layer will gradually loosen and erode, and the thickness of the insulation layer will be reduced, resulting in a decline in the overall heat insulation and energy sa...
