In recent years, with the rapid development of the construction industry and the high-speed rail industry, the double glazing has been widely used due to its good sound insulation, heat insulation, and UV protection.
The spacers used in the doub le glazing is made of color coated alluminum strip. After the surface is processed, the coated aluminum strip has high brightness, high flatness, uniform pores, anti-aging and beautiful decoration. At the same time, it is not easy to be oxidized, corrosion-resistant, and does not have any effect on the desiccant.
Since the aluminum spacer is a structural product that carries molecular sieve and isolates the original hollow glass and it will be exposed to the complex environment generated by cold and heat exchange, it is required to have high corrosion resistance.
In addition, in order to achieve the purpose of saving raw materials and lightening, the hollow glass aluminum spacer material is developing in the direction of thinner thickness, while taking into account the above-mentioned performance. Therefore, the selection of the chemical composition of the aluminum alloy strip is very imprtant. Its manufacturing method is an important factor in whether the aluminum spacer can meet the performance requirements.
At present, the existing aluminum spacer materials is of limted chocie. Among them, aluminum strip 1100 is one of the most commonly used materials for aluminum spacers. Why is the superior performance of the double glazing window inseparable from the aluminum spacer? The aluminum strip has sound absorption properties and good light reflection performance. The ability of aluminum strips to reflect ultraviolet rays is stronger than that of silver. The purer the aluminum strips, the better its reflection ability, so it is more suitable for hollow window.
The Specification of Color Coated Aluminum Strip for Spacer
Alloy | Temper | Thickness | Width | Coating |
1100 | H16 H18 H19 H26 | 0.2~0.4 mm | 20~500 mm | Normal gloss PE coating |
