Problems solved by technology

After the kiln is used for a long time, it will cause cracking, air leakage and serious heat dissipation. The resulting heat loss usually accounts for about 10% to 30% of the total heat consumption. At the same time, it also brings difficulties to the further improvement of product quality. The heat consumption of sintered bricks and tiles increases, resulting in energy waste, which not only increases the production cost of the brick factory, seriously even affects product quality, and shortens the service life of the kiln
The traditional method is to renovate the kiln and replace the refractory material. This method is costly and takes a long time, which increases the burden on the enterprise

Abstract

The invention relates to the technical field of sealing coating of a medical kiln and discloses a sealing coating composition of a kiln, which contains the following components in percentage by weight: 10-40 percent of high-alumina fried powder, 20-35 percent of high-alumina fried aggregate, 20-30 percent of quartz sand and 15-35 percent of sodium silicate. The product contains no toxic components, resists high temperature without easily cracking, effectively prevents air from leaking, lowers the thermal consumption by 10-20 percent after use, is a multifunctional material capable of filling up the crack and repair the damage of (kiln walls or a kiln car) and improving the insulation property of the wall body, is the most effective and economic and suitable ideal material for overcoming the defect of the prior tile kiln and has simple construction and low cost.

Description

technical field [0001] The invention relates to the field of sealing coatings, in particular to the field of sealing coatings for brick kilns. Background technique [0002] At present, sintered bricks and tiles are generally completed by using wheel kilns and tunnel kilns. After the kiln is used for a long time, it will cause cracking, air leakage and serious heat dissipation. The resulting heat loss usually accounts for about 10% to 30% of the total heat consumption. At the same time, it also brings difficulties to the further improvement of product quality. The heat consumption of sintered bricks and tiles increases, resulting in energy waste, which not only increases the production cost of the brick factory, seriously even affects the product quality, and shortens the service life of the kiln. The traditional method is to renovate the kiln and replace the refractory material. This method is costly and takes a long time, which increases the burden on the enterprise. Peop...
