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…

Tungsten acid may be applied for the production of window heat insulation film, which offers a distinctive blend of energy efficiency, user comfort and security. 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…

Tungsten acid can be applied for producing thermal insulation coating, thereby this kind of heat-insulating dingal coating will has good performance of shielding near-infrared light (near-infrared rays). Infrared light is a kind of non-visible light (electromagnetic wave), whose wavelength is between microwave and visible light, at the range of 750nm~10^6nm. Infrared light can be divided into three types including near-infrared light, medium-infrared light and far-infrared light. Among them, the near-infrared light has a wavelength range of about 750~1400nm, which has…

Tungsten acid may be applied for preparing thermal insulation film with different applications, such as, automotive glass, building glass, and so on. This kind of automotive film can prevent glare, so that the driver has a clear view to ensure traffic safety. And this film isolates 90% of ultraviolet rays to prevent discoloration and aging of rubber and plastic parts in car. Besides, it reduces the secondary damage to human when the glass is broken. Preparation of Thermal Insulation Film…

Tungsten acid may be applied for thermal insulation paper to make this kind of paper has good shielding effect on light intensity and ultraviolet ray. In other words, the paper will have high heat insulation effect. Also, it will have the advantages of no pollution, corrosion resistance and wear resistance. As we all have known, ultraviolet rays cause textile, leather and furniture fading. And the UV is also one of the important factors of skin cancer. As people’s living standard…

Tungsten oxide (WO3) may be used to produce ceramic microsphere, in which WO3 is of nano grain size. Nano ceramic microsphere is the ceramic material whose grain boundary width, grain size, defect size, and second phase distribution are all on the order of nanometers. More and more attention is paid to ceramic microspheres as they overcome the disadvantage of larger brittleness of traditional ceramics. And this kind of ceramic material is excellent in electrical properties, mechanical properties and other special…
