How to improve the thermal insulation performance of insulating refractory bricks

In today's industrial field, the thermal insulation performance of insulating refractory bricks is of vital importance to improve energy efficiency and reduce production costs. Dongtai Hongda is committed to providing customers with high-performance insulating refractory brick products by relying on its continuous innovation in raw material selection, production process and molding technology.

Optimize raw material selection and ratio
The selection and proportion of raw materials are key factors in improving the thermal insulation performance of insulating refractory bricks. Dongtai Hongda adheres to high standards and uses high purity refractory raw materials, including high quality silica and high alumina clay. These raw materials not only have excellent bonding properties, plasticity and firing shrinkage, but also have sufficient refractoriness. After strict raw material screening and scientific ratio design, the company's products have been significantly improved in thermal insulation performance and overall strength. In addition, Dongtai Hongda Company actively explores the application of new raw materials, such as expanded perlite and iron oxide powder. The introduction of these new materials not only improves the thermal insulation effect of the product, but also enhances its high temperature resistance, providing customers with more competitive product choices.

Innovative production process and molding technology
In the production process of insulating refractory bricks, innovation in process and molding technology is also crucial to improving product performance. Dongtai Hongda Company has introduced advanced automatic batching and molding production lines, which ensure the uniformity and density of the internal structure of the product through precise batching and fine molding technology. In addition, the company also adopts advanced firing technologies such as high-temperature tunnel kilns and shuttle kilns to ensure the formation of a more stable insulation layer inside the product by precisely controlling the firing temperature and insulation time. The application of this technology not only improves the thermal insulation performance of the product, but also provides a guarantee for the long-term stability of the product.

Application of plasticizers and combustible additives
In order to further improve the thermal insulation performance of insulating refractory bricks, Dongtai Hongda Company implemented the strategy of adding plasticizers and combustible additives. Plasticizers, such as inorganic or organic substances such as bentonite, significantly improve the plasticity and molding properties of raw materials, making the product denser during the firing process and effectively reducing the transfer of heat. At the same time, adding combustible materials can form more pore structures during the firing process. These pores effectively block the heat transfer path and further enhance the insulation effect. However, it is worth noting that the particle size and shape of the combustible additives have an important influence on the final thermal insulation performance, so strict control is required during selection and proportioning.
