Three major properties that insulation must have

First, good flame retardant performance and environmental protection

The insulation layer should be in contact with the heating pipe. The temperature of the heat medium can reach 45-60 degrees Celsius. The organic material will volatilize the toxic or odorous gas, which is not good for human health. This is the insulation material for the exterior wall or roof. the difference. The development of composite materials with good thermal insulation and flame retardancy will be the development direction.

Second, high resistance to deformation and compression

The insulation layer is subjected to pressure from the heating pipe, the concrete filling layer and the active load on the floor and the floor. Therefore, if the material of the insulation layer does not have sufficient load-bearing capacity, the concrete filling layer and the floor may appear due to uneven deformation of the pressure. Cracks, or situations in which the heating pipe is not deformed at a higher temperature to reduce the service life. Foamed cement is recommended for large-area construction because of its high pressure resistance.

Third, good thermal insulation performance

Insulation materials with good thermal insulation effect can prevent heat from being transmitted to the floor and lost to neighbors, ensuring that heat is transmitted to the room in one direction. The index reflecting the thermal conductivity of the material is the coefficient of thermal conductivity. The factors affecting the thermal conductivity of the material are material, porosity, open state, humidity, and ambient temperature. The thermal conductivity of different kinds of materials is also different; the thickness of the thermal insulation layer required for the thermal resistance of the different properties to meet the design requirements is different; the same material, different bulk density, and thermal conductivity are also different. The higher the porosity of the material, the more the closed pores, the lower the thermal conductivity, the better the thermal insulation performance, and the different water-containing states and thermal conductivity.
