Material requirements for single-sided color steel phenolic board: the board, model and other finished materials used in the production and installation of air duct shall meet the requirements of design and relevant national product standards. The single-sided color steel phenolic board material shall have factory quality inspection certificate. The materials of one-sided color steel phenolic Board shall be accepted according to the current relevant standards. The variety, specification, performance, thickness and other technical parameters of composite plate shall meet the design requirements. The composite surface of one-sided color steel phenolic Board shall be firmly bonded, and the defects such as delamination and blistering on one side of the bonding surface shall not be more than 6 ‰.

The material of composite duct plate must be non combustible material, and the internal foam insulation material with heat preservation property should be no less than GB8624 B1 grade. Materials such as flange connectors and reinforcements shall not be lower than Class B1. The adhesive, aluminum tape and glass adhesive used shall match with the material of the plate, and shall meet the environmental protection requirements.

What are the principles of thermal insulation of aluminum foil thermal insulation materials

There are three ways of heat transfer in building heat exchange: conduction + convective heat < 25%, radiant heat > 75%. When the temperature of one-sided color steel phenolic tile roof rises in summer, a lot of radiant heat enters into the room, causing the temperature to rise continuously, which makes the working and living environment very uncomfortable. The solar radiation absorption coefficient (normal total radiation rate) of the aluminum foil insulation coil is 0.07, and the radiation heat is very little. Compared with other thermal insulation materials, the aluminum foil thermal insulation coil is laid in large area, and the single-sided color steel phenolic board material hot bridge (cold bridge) is treated extremely well. In summer, it plays an outstanding role in thermal insulation. In winter, it has outstanding thermal insulation function, and then it really reaches the intention of saving energy consumption.

1. Heat energy transmission Road (without heat insulation film): the sun infrared magnetic wave heat energy bumps the tiles to raise the temperature - the tiles become a heat source to radiate heat energy - the heat energy bumps the cast-in-place roof to raise the temperature - the cast-in-place roof becomes a heat source to radiate heat energy - the indoor environment temperature continues to rise.

2. Heat energy transmission Road (with heat insulation film): the sun infrared magnetic wave heat energy bumps the tiles to raise the temperature - the tiles become a heat source to radiate heat energy - the heat energy bumps the aluminum foil to raise the surface temperature - the aluminum foil emissivity is extremely low, radiates a small amount of heat energy - the comfortable environment temperature is adhered to indoors.
