Polyester coated aluminium sheet is cured at high temperature, and has the characteristics of corrosion resistance, strong hardness, high temperature resistance, bending resistance and earthquake resistance. At the same time, it has a compact structure, light weight, convenient construction, safety and durability. It is widely used in construction field.
PE is polyester coating, PE coating is a layer of plastic sprayed on the surface of color coated aluminium sheet, which is mainly moisture-proof and anti-corrosion. Polyester is a high molecular organic compound, which is generally liquid, colorless, odorless, insoluble in water, and has a density of 0.92 g/cm3, it can be used as lubricating oil and paint. The polyester painted aluminium sheet is corrosion resistant and has good insulating properties. Polyester coating is insoluble in water and has very little water absorption. Even for some chemical solvents, such as acetic acid, it is only slightly dissolved at a temperature above 70 °C. However, particulate polyethylene can be melted or solidified with the change of temperature between 15 ° C and 40 ° C. When the temperature rises, it melts and absorbs heat; when the temperature decreases, it solidifies and releases heat. And because it absorbs little water, it is not easy to get wet, and it has insulating properties, so it is a good building material.
Polyester coated aluminium sheet can be used for walls and roofing. Using its characteristics of endothermic melting and exothermic solidification at normal temperature, when the room temperature rises, it melts and absorbs heat; when the temperature drops, it solidifies and releases heat. This keeps the room temperature stable. Therefore, it is a better heat storage material. According to its other characteristics, this building material is also anti-leakage, heat-proof, moisture-proof and corrosion-proof.
