Wiper Seals are a type of mechanical seal commonly used to protect piston rods and pistons in hydraulic and pneumatic equipment. The main function of Wiper Seals is to prevent dust, dirt, and other impurities from entering the interior of the equipment, thereby protecting the sealing performance of the piston rod and piston, and extending the service life of the equipment.
Wiper Seals are typically made of elastic materials such as polyurethane, nitrile rubber, fluororubber, etc. These materials have excellent wear resistance and chemical resistance, and can maintain stable performance in various harsh environments.
Wiper Seals are typically divided into two types: unidirectional and bidirectional. Unidirectional Wiper Seals can only prevent dirt and impurities from entering the device from one direction, while bidirectional Wiper Seals can simultaneously prevent dirt and impurities from entering the device from both directions.
Wiper Seals can also be customized according to different application requirements. For example, for high-speed rotating devices, special Wiper Seals can be used to ensure that they do not generate excessive heat and friction during high-speed rotation. For equipment used in harsh environments, special materials such as corrosion-resistant, high-temperature resistant, and low-temperature resistant Wiper Seals can be used.
In summary, Wiper Seals are in dispensable mechanical seals in hydraulic and pneumatic equipment, and their excellent performance and reliable sealing performance provide important guarantees for the normal operation of the equipment. If you need a Wiper Seals product, you can contact a professional seal manufacturer to customize the appropriate Wiper Seals for your device according to your specific needs.

In 2013, Delia Milliron, a professor at the University of Texas School of Electrical Engineering at the University of Texas at Austin, and her research team pioneered the development of an electrochromic material that can be used to selectively control visible light and generate heat. Infrared light. According to the research team's demonstration, they can use a small amount of current to switch back and forth between nanocrystalline materials, which enables separate control of light and heat.
Now, the research team has realized two new technological breakthroughs on electrochromic materials: a highly selective cooling and warming mode. Cool mode material is a major advancement for the commercialization of products because it can achieve 90% of near-infrared light control and 80% of visible light control, and mode switching can be completed in only a few minutes. In addition, the R&D team has developed a novel nanostructure for this electrochromic material that allows it to pass visible light while blocking near-infrared light.
In another study, the research team also demonstrated a film that could bring light control to the window. This film adds titania nanocrystals that dynamically control the penetration of solar radiation. While blocking visible light, it allows near-infrared light to pass through. In sunny winter days, this feature will become practical.
