Insulated glass is manufactured through sealing two or more float glasses with high-strength air-tightness composite viscose. There are aluminum alloy partitions filled with drying agents between the sheet glasses, which makes the air inside the glasses very dry, butyl rubber seal is used as the first line, the second seal use glass or plastic polysulfide adhesive on the basis of the used framework of the glasses. The space between the glass and glass is isolated from the outside world by sealant, there is a special gas or air, insulating glass has good performance of heat insulation and noise insulation.

Nickel foam plate is a type of porous material made from nickel metal. It consists of a three-dimensional network of interconnected nickel fibers or filaments that form a highly porous structure. The foam-like structure of nickel foam plate provides a large surface area, high porosity, and good electrical conductivity, making it useful for various applications in fields such as energy storage, catalysis, filtration, and aerospace. Product parameter Material: Nickel Aperture: 0.3mm-7mm(can customized) Porosity: 63%-90% The Max Sound Absorption Coefficient: â?¥0.8 Bulk Density: 0.27-1.08 g/cm3 Size: Customized Feature 1. Quality and light: maximum surface area, specific gravity 0.2 to 0.3, 1/10 of water, and wood, aluminum, and iron. 2. The porous construction has an extensive frequency range of sound absorption. 3. Electronic wave shield: It is protected by a 90 dB or so thick electronic wave that is rather thin. 4. Processing performance: It is easily adhered, decreased, and bent. 5. High temperature fire resistance: The stable form burns at a high temperature but is difficult to burn. 6. The ability to filter: The uniform three-dimensional network structure produces a filtering effect and permits extremely robust gas and fluid flow stability. Application 1.Nickel foam plate is a sound-absorbing material with excellent performance, which has a high sound absorption coefficient at high frequencies; the sound absorption performance at low frequencies can be improved through the design of the sound-absorbing structure. 2.Battery electrode material Nickel foam plate is the most common material used for battery electrodes, particularly for NiMH batteries. These rechargeable batteries are frequently found in hybrid cars, laptop computers, cell phones, electric scooters, and bicycles. 3. Fuel cell Foamed nickel can be used as an electrocatalyst for molten carbonate fuel cells, which typically operate at temperatures between 550 and 700 �° C. For proton exchange membrane production cells (PEMFC), electrode relay feeders for solid oxide fuel cells (SOFC), and electrode materials for electrolysis (as in water electrolytic settings), nickel foam plate can be utilized. Additionally, more surface area can be employed to produce syngas and hydrogen for fuel cells. 4. Other applications Magnetic flux conductors of magnetic particles in a fluid can be treated using nickel foam plate as a filter material. Applications to heat exchange medium and hydrogen storage media are among the further uses.
