Technical Field

The invention belongs to the technical field of heating equipment, and particularly relates to a floor heating plate.

Background

The floor heating board is a floor suitable for low-temperature hot water floor heating (floor heating for short). Measuring the actual floor heating panel requires many specific technical parameters. First, it must have good heat dissipation. The floor heating board is very exquisite in material selection, and special base materials with wood density meeting the requirements are strictly selected to ensure that the floor has good air permeability and heat dissipation function; the second property is heat resistance; and the third is environmental protection, how to judge the formaldehyde emission index of the composite floor heating board, or if judging the pure solid wood floor heating board to achieve the characteristic requirement of hundred percent environmental protection arrangement. Fourth is security.

The condition that the floor heating is used in the northeast area of China is obvious, the temperature of the northeast area is low all the time, so the floor heating is in an open state all the time, the damage to the floor heating plate is small, but the temperature of partial areas in China is not in a severe cold period like the northeast area for a long time, so the floor heating is in a discontinuous open state for saving energy, the floor heating plate generates obvious expansion and contraction conditions in the environment with sudden cold and sudden hot, and the service life of the floor heating plate is greatly reduced.
