Medium temperature coal asphalt manufacturer Mengbei
Modified asphalt powder plays an important role in refractory materials. It acts as a binder and insulating layer to improve the resistance of refractories to high temperature softening and thermal shock, extending their service life, while also insulating and protecting the mineral particles inside from high temperature damage.
First of all, the modified asphalt powder is used as a binder, which can firmly bond the mineral particle substances in the refractory together to form a uniform and dense refractory structure, and improve the high-temperature strength and thermal shock performance.
Secondly, the modified asphalt powder is used as a thermal insulation layer, which has a low thermal conductivity coefficient, which can effectively prevent heat transfer to the interior of the refractory material, thereby protecting the mineral particles inside from high temperature damage. This not only extends the service life of the refractory, but also improves the thermal insulation of the refractory.
In addition, the modified asphalt powder also has good chemical stability and thermal stability, small thermal expansion coefficient, can maintain the original performance and form in a high temperature environment, and can inhibit the overall expansion of refractories. Therefore, modified asphalt is often used as one of the important additives in the production process of refractory materials to improve the performance and stability of refractory materials.
In general, modified asphalt powder can improve the high temperature softening and thermal shock resistance of refractories in refractories, prolong the service life, improve the thermal insulation effect and protect the mineral particles inside from high temperature damage, and make an excellent contribution to the stable development of refractories.
