How to improve the strength of insulating refractory bricks

In today's industrial applications, the strength and performance of insulating refractory bricks directly affect the safety and production efficiency of equipment. Dongtai Hongda Company continues to explore and innovate in this field, and is committed to improving the overall performance of insulating refractory bricks by optimizing raw material selection, improving production processes, and adding reinforcing agents and binders.

Optimizing raw material selection and proportioning
The improvement of the strength of insulating refractory bricks is inseparable from the careful selection and scientific proportioning of raw materials. Dongtai Hongda Company selects high-purity refractory raw materials, including high-quality siliceous and high-alumina clays. These raw materials not only have excellent bonding properties, but also have high refractoriness. During the raw material screening process, the company strictly controls the impurity content to ensure uniform particle distribution, thereby improving the overall strength of the product. In addition, Dongtai Hongda is also actively exploring the application of new raw materials, such as adding hard particles such as quartz sand and corundum in appropriate amounts. These hard particles can form a stable skeleton structure during the firing process, thereby further enhancing the strength and durability of the product.

Improving production processes and molding technologies
The innovation of production processes and molding technologies is an important part of improving the strength of insulating refractory bricks. Dongtai Hongda Company introduced advanced automated batching and molding production lines to ensure that each batch of products has accurate batching and stable shape. During the molding process, the company uses high-pressure molding technology to increase the molding pressure to make the raw material particles more closely bonded, thereby significantly improving the density and strength of the product. At the same time, Dongtai Hongda has also introduced advanced firing technologies such as high-temperature tunnel kilns and shuttle kilns. By accurately controlling the firing temperature and insulation time, a more stable crystalline structure is formed inside the product, further improving its strength and fire resistance.

Adding reinforcing agents and binders
In order to further improve the strength of insulating refractory bricks, Dongtai Hongda Company adopted the strategy of reinforcing agents and binders in the production process. Reinforcing agents such as alumina powder and silica fume can significantly improve the firing properties and bonding strength of raw materials. Inorganic gelling materials such as binders such as cement and water glass form chemical bonds during the firing process, firmly binding the raw material particles together, thereby improving the overall strength of the product. It should be emphasized that the amount of reinforcing agents and binders added must be strictly controlled. Excessive amounts may lead to a decrease in product performance or cause other adverse effects.
