As a special desiccant, both powdered and spherical zeolite can be applied to insulating glass spacers.
The insulating glass spacer is the skeleton of an IGU (Insulating Glass Unit), which supports and separates the two panes of glass. The spacer acts as a sealant to prevent air and moisture from entering the space between the glass panes, which helps to improve the energy efficiency of the window.
From early blowing, welding to gluing, the advancement of spacing technology has greatly improved the performance of insulating glass.
Zeolite in Aluminum Spacers
Aluminum spacers are a popular choice for IGUs due to their strength, durability, and energy efficiency. Unlike other types of spacers, aluminum spacers will not warp or bend over time, ensuring a tight, air-tight seal between the glass and the spacer. Additionally, aluminum spacers are highly resistant to heat transfer, which helps to maintain the energy efficiency of the IGU.
The aluminum spacer, acts as a container for the zeolite molecular sieve, storing the molecular sieve and maintaining its function, allowing the molecular sieve to absorb moisture from the hollow layer through the gaps and prevent air and water vapor from entering the hollow layer. The aluminum spacer and the zeolite molecular sieve work together to prevent gas leakage and moisture penetration inside the insulating glass.
Zeolite in Warm Edge Spacers
Warm edge spacers are an innovative solution for those looking to improve the energy efficiency of the IGU. Unlike traditional metal spacers, warm edge spacers are designed to reduce heat loss at the edges of the glass, and provide better support to lessen the temperature difference between the window frame and the glass, thereby reducing the risk of condensation on the insulating glass.
The warm edge spacer, is made from a variety of rigid or flexible hybrid materials, including modified plastic, butyl, silicone and metal. And the zeolite activated powder is used to blend into the hybrid material, to remove moisture and odors, thereby maintain the stable performance of the warm edge spacer.
Zeolite Option for Insulating Glass
For aluminum spacer bars, type 3a zeolite bead is the standard choice for insulating glass desiccant. 3A zeolite beads can effectively adsorb water molecules, avoid adsorption of air and the “breathing effect” caused by temperature changes, and ensure the stable performance of insulating glass.
For warm edge sealants, it is necessary to select the appropriate zeolite powder type and specification, to meet the specific requirements of the warm edge sealants. Besides, the addition ratio must strictly follow the process requirements to ensure the zeolite powder is evenly distributed, so as to control the quality of the sealant.
As a brand manufacturer, SNOWPEAK can supply both spherical and powdered zeolites for insulating glass industry, and its self-developed products already have mature applications.
