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 SpacerAlloy Temper ThicknessWidthCoating1100 H16 H18 H19 H26 0.2~0.4 mm20~500 mmNormal gloss PE coating 30033105   Color Coated Aluminum Strip for Spacer Posted by: RogerTib - 06-12-2023, 02:02 AM - Forum: Knowledge & Technique - No Replies The double glazing window is made of two ieces of glass, using a high-strength and high-air-tight composite adhesive to bond the glass pieces to the aluminum alloy frame containing a desiccant to make high-efficiency sound and heat insulation glass.The aluminum spacer is specially made for the hollow window. This color coated aluminum strip is an aluminum product made of high-purity aluminum. After processing, it is not easy to oxide and corride, and has no effect on the desiccant, effectively eliminating the phenomenon of atomization. It can have good friction resistance during use, and will not loosen during use.The moisture in the hollow glass is quickly absorbed by the molecular sieve inside the aluminum spacer, which effectively eliminates the phenomenon of atomization. The molecular sieve inside the aluminum spacer does not overflow, so that the inside of the hollow glass is dry and tidy.There are two rows of water drop patterns on the surface of the aluminum spacer, which makes the glass doors and windows look more high-end and beautiful. It can be bent to improve the production efficiency of double glazing window. When connecting the glasses, the aluminum spacer has a strong stabilizing effect, and it has more functionality in design.The common alloys are 1100. 3105 and aluminum strip 3003. Aluminum strip 3003 has very good reflection performance to light. It reflects ultraviolet rays stronger than silver. It also has strong low temperature resistance. When the temperature is low, aluminum will increase its strength without brittleness, so it is an ideal material for low-temperature devices. All these advantages make aluminum strips capable of being hollow window spacer.Haomei aluminum strip for window spacer has been exported to many countries and regions worldwide. The packaging has two types: large aluminum strip roll packaging and wooden case packaging. The size of the roll is determined by the width and length of the roll according to the customer's customization. The approximate dimensions of the wooden box is 1.4 meters in length, 1.3 meters in width, and 0.8 meters in height.
