Protect the kiln, improve the production efficiency of the kiln, extend the use time of the kiln, save energy, and bring economic benefits to the enterprise. The kiln is a high temperature equipment cast from high temperature resistant materials for calcining or firing the product. The materials heated by the kiln are coal, wood, oil, gas, natural gas or electromagnetic induction. The temperature of the kiln can reach 1600 ° C or higher, there is a large amount of corrosive medium in the environment, the air flow is large, and the material of the kiln is corroded and the friction loss is serious. In order to better protect the kiln materials, energy saving and environmental protection, the kiln work is more continuous, so the anti-corrosion at the high temperature of the kiln is extracurricular. The specific applications of high-temperature furnace kiln energy-saving coatings are as follows:
1. The high temperature material of the kiln is insulated brick. The protection of the thermal insulation brick also becomes the anti-corrosion of the thermal insulation brick. The thermal insulation brick has the high quality and low quality. After the thermal insulation brick works in the high temperature kiln for 3-5 years, the thermal insulation brick will be crispy. Shedding, serious image of the safety and thermal insulation of the furnace. The protective anti-corrosion method of the thermal insulation brick is to apply ZS-1 high temperature thermal insulation coating on the surface of the thermal insulation brick to reduce the heat of the thermal insulation brick and the corrosion medium, and then recoat the ZS-1 high temperature thermal insulation coating. Brush ZS-1061 high temperature resistant far infrared radiation coating, increase the combustion temperature of the kiln, reduce the exhaust gas temperature, is the energy fully extended, so the energy saving economic benefits are particularly prominent.
2, the high temperature material of the kiln is metal, the corrosion of the metal is very serious at high temperature. After the metal surface treatment, the ZS-1 high temperature heat insulation coating is applied first, and the heating temperature of the metal is less, the metal is in the high temperature environment. The performance does not change, and the limit shows the performance of the metal. ZS-811 high temperature anti-corrosion coating is applied on the outer surface of ZS-1 high temperature resistant thermal insulation coating. The high temperature resistant anticorrosive coating can reach 1800 °C, acid and alkali resistance, anti-airflow impact, and can protect furnace kiln combustion. The corrosive gas generated during the reaction does not react with the metal, which greatly prolongs the service life of the kiln metal.
3. The high temperature material of the kiln is insulation cotton or thermal insulation felt. Apply ZS-1011 fiber transition coating on the insulation cotton or insulation blanket, and apply ZS-1061 high temperature resistant far infrared radiation coating. The degree of corrosion of thermal insulation cotton or thermal insulation felt, better play the thermal insulation of thermal insulation felt or thermal insulation cotton, the aging of the link materials, and extend the service life of thermal insulation cotton or thermal insulation felt.
4. The high temperature material of the kiln is graphite and silicon carbide. The oxidation of graphite and silicon carbide at high temperature is severe and the corrosion is serious, which will affect the normal operation of the kiln. ZS-1011 transition coating is applied to high temperature graphite and silicon carbide, and high temperature sealing coating is applied to increase the anti-oxidation ability of graphite and silicon carbide, reduce corrosion and increase the service conditions and years of furnace.
High-temperature furnaces are important and extremely critical equipment for industrial production. Energy-saving of furnaces and kiln is also the key to energy conservation in the industry. Energy-saving and emission reduction is a strategic measure that follows the laws governing the development of human society and conforms to the development trend of today's world. Since the industrial revolution, the rapid development of the economies of all countries in the world, especially the Western countries, has been at the expense of a large amount of energy resources, and has caused the deterioration of the ecological environment. Further strengthening the energy-saving and emission reduction work of the kiln is not only the deepening of the understanding of the laws governing the development of human society, but also the urgent need to actively respond to global climate change and the strategic choice of taking a new road to industrialization.
