Lightweight thermal insulation castables are a kind of building material with excellent performance, economical and practical, and its main features can be summarized as follows:
Lightweight and low density: The density of lightweight thermal insulation castables is very small, and the weight per cubic centimeter is approximately between 0.4 and 1.2 grams. This light texture not only reduces the load on buildings or equipment, but also makes construction easier and reduces transportation and installation costs.
Excellent thermal insulation performance: Lightweight thermal insulation castables have a low thermal conductivity coefficient, which can effectively prevent the transfer of heat, thereby reducing energy consumption. This excellent thermal insulation effect makes it play an important role in the thermal insulation of the exterior walls, roofs, floors and other parts of the building. In the thermal insulation of the exterior wall, lightweight thermal insulation castables can form a continuous thermal insulation layer, avoid the thermal bridge effect, and improve the overall thermal insulation performance of the wall. In the thermal insulation of the roof, it can form an thermal insulation layer, effectively insulate, and make the indoor temperature more stable and comfortable. In floor insulation, lightweight insulation castables not only improve insulation performance, but also reduce the weight of the floor and enhance the stability of the building structure.
High temperature resistance: lightweight insulation castables can maintain stable performance in high temperature environments, and the heat resistance temperature can reach above 1000℃. This makes it possible to use lightweight insulation castables in high-temperature equipment such as industrial furnaces, electric furnaces, and converters. In these occasions, lightweight insulation castables can not only effectively insulate, but also improve the thermal efficiency of equipment and extend its service life.
Good compressive strength and impermeability: Although lightweight insulation castables are light in weight, they still have high compressive strength and can ensure the stability of the equipment. At the same time, it has fast strength growth and strong impermeability, which can significantly improve the air tightness, integrity and corrosion resistance of the chimney lining wall.
Corrosion resistance: lightweight insulation castables can resist the erosion of chemicals, acids and alkalis and other media, and are suitable for some highly corrosive environments.
Convenient construction: Lightweight thermal insulation castables have good fluidity and plasticity, and can adapt to various irregular surfaces or spaces for construction. Whether pouring, applying or spraying, it can be easily completed, greatly improving the construction efficiency. This convenience not only reduces the difficulty of construction, but also shortens the construction period, providing a strong guarantee for the smooth progress of the project.
Environmental performance: Lightweight thermal insulation castables generally use environmentally friendly inorganic materials and do not contain harmful substances. Compared with traditional thermal insulation materials such as polystyrene boards, lightweight thermal insulation castables do not release volatile harmful gases during production and use, and have no negative impact on human health and the environment.
In addition, lightweight thermal insulation castables have many pores, low volume density, good workability, strong adhesion, long initial setting time and construction operation time. These characteristics make lightweight thermal insulation castables a building material with excellent performance and are widely used in thermal insulation projects in power, petrochemical, metallurgy, kilns and other industries.
