In modern society, industrial (kiln, pot, etc.) furnace body will produce a certain heat loss in the production process. Heat loss mainly includes heat dissipation loss and heat storage loss. Heat loss is the heat lost from the outer wall of the boiler, and the boiler with poor insulation measures often has more serious heat loss; Heat storage loss is the heat lost when the furnace body rises with the change of temperature in the furnace. For industrial furnaces with periodic operation requirements, heat storage loss is more serious. Continuous operation furnaces also have heat storage loss when the furnace is stopped and started.

In order to reduce heat loss, materials with thermal insulation properties can be used to reduce heat loss. In the general sense, thermal insulation materials are divided into three types according to the form: coil, plate and coating. According to the material category, it is divided into: polyurethane, aluminum silicate fiber, glass fiber, aerogel, etc. Aluminum silicate products, glass fiber products, etc., are commonly used thermal insulation materials, and the thermal conductivity is about 0.03-0.05. Polyurethane insulation performance is slightly better, but it is not able to withstand high temperatures, and easy to burn, the production process is not environmentally friendly, and has been slowly replaced in industrial use. Aerogel products are new thermal insulation materials, and the thermal conductivity is about 0.018-0.03. Common aerogel materials are: aerogel felt, aerogel coating, aerogel ultra-thin cloth and so on. Pure aerogel materials have low thermal conductivity, but are also relatively brittle and rarely used alone in practical applications. It is usually combined with glass fibers to make aerogel felt. Combined with other high temperature resistant special ingredients, it can be made into aerogel thermal insulation coating. Aerogel thermal insulation coating has a high temperature resistance of 600 degrees, which solves the high temperature resistance of ordinary aerogel materials. At the same time, due to the low thermal conductivity of aerogel materials and the high thermal conductivity of other materials, the combination of the two is bound to be higher than the thermal conductivity of aerogel. The research and development department of Bailuhan Company through the combination of special materials and special structures, so that it can be reduced to the highest degree to the low thermal conductivity of the aerogel itself. At the same time, the coating state can be more closely fitted to the thermal insulation equipment, perfect fitting, no gaps, holes, not limited by the equipment, more able to meet the sealing requirements, and better achieve the thermal insulation effect.

Aerogel thermal insulation coating has low thermal conductivity, water-based environmental protection and easy construction, good sealing performance combined with other coatings, long service life, especially suitable for long-term pipelines and furnace body insulation materials without frequent disassembly, especially suitable for the production process has temperature requirements, the use of electric heat tracing and other auxiliary heating pipelines and equipment, can save the use of electric heat tracing, easy to meet the temperature requirements.

Through the use of aerogel thermal insulation coating can achieve energy saving and consumption reduction of industrial furnace (3%-12%), extend the service life of the furnace body (more than 5 years), low investment cost, high economic efficiency, according to the actual thermal insulation needs, in the furnace body of the outer wall, sandwich, inner wall coating can be simple construction, thin coating, more advantages than traditional thermal insulation coil sheet!
