Ammonium metatungstate may be applied for producing thermal insulation film. Ammonium metatungstate enables this kind of dingal film to block near-infrared rays. And its infrared shielding rate is as high as more than 90%. Moreover, this film has good visible light transmittance, which is higher than 80%. Therefore, it can save energy consumption by 20-30% when used in building glass. What’s more, from the point of view of application, this kind of dingal film has weather resistance, anti-aging, and long…

Ammonium metatungstate may be used for the manufacturing of thermal insulation paper so that this type of dingal paper may have good thermal insulation effect, with infrared insulation rate higher than 90%. Also, the thermal insulation paper has the characteristics of fire resistance, high temperature resistance, high flexibility, high tear resistance and low thermal conductivity. Thus, it is mainly used for building insulation, or as lining of various industrial furnaces and high-temperature pipes. All these are due to the adding…

Tungsten acid may be applied for the production of ceramic microsphere, which has the characteristics of excellent spectral selectivity and stability. Therefore, the visible light transmittance of this type of ceramic microsphere is more than 80%, and the near-infrared shielding rate is 90% or above. It means that the heat insulation effect of this kind of ceramic material is excellent, which may save energy consumption of 20-30% when it is applied in building glass. At present, for thermal insulation, nano…

Tungsten acid may be applied for the preparation of nano-ceramic color master so that the color master may has the advantages of high transparency, high heat insulation and low haze value. The infrared ray blocking rate of this type of nano-ceramic color master is 60~99%. The visible light transmittance is 50~80% and the haze value is less than 1. The nano-ceramic color master is widely applied in transparent plastic sheet, transparent heat-insulating film, transparent sunshade products and other products that…

Tungsten acid may be used as the material for the preparation of nano-ceramic dispersion solution. Thus, this kind of dispersion solution has the advantages of anti-aging, shielding of ultraviolet rays and infrared rays, good coloring, flame retardance, and excellent light transmittance. And therefore, it can be applied in the architectural glass and automobile glass to improve comfort and energy efficiency. Shielding Effect Visible light transmittance is greater than 70%. Infrared light blocking rate is greater than 90%. Ultraviolet light blocking…

Tungsten acid can be applied in near-infrared shielding material, which precisely controls the amount of light, glare and heat passing through, reducing the need for air conditioning during the summer months. Tungstic acid enables near-infrared shielding material to have the following advantages: 1. Not easy to fade with long service life; 2. Anti-UV up to 99% with high light transmission, preventing interior furniture or ornament from fading; 3. Block glare. When it is applied in automobile, it makes drivers drive…

Tungsten acid may be applied for heat insulating window glass, which provides for better user comfort and well-being and improves energy efficiency. Nano tungsten acid plays a role of heat insulation film on the window glass of vehicles. The heat insulating film provides over 99% UV blockage. In cars, the range of light transmission for this type of window glass is 50-60 times darker than a typical sunroof to twice as clear as an ordinary sunroof. Commercialization of heat insulating…

Advantages of Window Heat Insulation Film 1. Minimize glare. 2. Maximize daylighting. 3. Reduce cooling requirements. 4. Preserve daytime and nighttime views. 5. Allow people to enjoy shading on-demand. 6. Protect interior furnishings and artwork from fading. 7. Explosion-proof and not easy to fade. The window heat insulation film is a choice for smart window.…

Tungsten acid can be applied for the manufacture of thermal insulating glass. Tungstic acid belongs to the category of inorganic absorbents and has similarity with inorganic absorbents. Comparison of Infrared Absorbers 1. Organic absorbents, such as synthetic dyes, cost less. But, it has the disadvantage of poor heat resistance and easy decomposition. 2. Inorganic absorbents, such as metal complexes, have the advantages of high reflectivity, safety, and high durability. While their prices are relatively high. When installed in the envelope…

Tungsten acid can be applied for the preparation of heat insulation coating. Then, this type of coating has good ding of shielding infrared rays, and therefore can be applied as thermal insulation film for buildings, automobiles, and the like. Shielding Principle of Infrared Rays Infrared rays (IR) have longer wavelengths than those of visible rays. IR wavelengths extend from the nominal red edge of the visible spectrum at 700nm, to 1mm. Heat insulation coating materials are mostly added with near-infrared…
