What’s tungsten oxide?
Tungstenoxide has a molecular composition of WO3 and an molecular weight 2318.55.
It is a product of the tungstic anhydride. It includes tungsten dioxide as well as the tungsten anhydride. There are currently no tungsten products in industrial production. There are five types of tungsten-trioxide salts: tungstic, sodium, calcium, tungstates, ammonium partungstates, ammonium métatungstates and others based on their tungsten content.
Tungstentrioxide is an orange triclinic powder. Tungsten trioxide turns to an orange tetragonal cristal when the temperature is above 740° C. The crystal then returns back to its original condition after cooling. Stable in the air, melting temperature is 1473 °C, boiling points are higher than 1750, and relative density is 7.16.
Tungsten dioxide is the most stable of all the tungsten oxides. It is not easily soluble in water nor in other organic acids, apart from hydrofluoric. In hot concentrated sodium hydroxide, and ammonia it forms soluble “tungstate”. You can lower the temperature to below 650 ° C with H2 or by C at 1000-1100 C in order to get tungsten dust.
Applications of tungsten dioxide transparent insulation material:
Our home lives are made easier by smart homes. It’s also more energy efficient and greener, which makes it a very artistic way to live. It’s therefore no surprise that the smart sunlight room will be created. This is called intelligence. It can make the sunroom in summer heat like a fire stove and cool it down during winter. These transparent semiconductor materials (e.g. tungstenoxide transparent insulation materials) can “warm the room in winter” and make it cool in summer. My view is that air conditioning and heating are not required. But, they can help to insulate the sun room’s heat.
It is the concept of the “smart home” that we are referring to. The application of this idea has been widely adopted in everyday life. Unfortunately, the author cannot live an intelligent and fulfilling life. So, the typical home scene emerged: author went out on every occasion, only to suddenly remember that I had not locked the doors. Turn the air conditioner off. You won’t be able to survive this day if the air conditioner isn’t on. Be late to work, however! It’s time to switch to smart home! Once you have locked the door, open the smart home app to verify the status of your home. This makes the author sigh. Smart home puts people at ease.
A similar situation is to move to a smart sun room. Some sunrooms have Low-e glasses. A number of experiments were conducted to determine the ultraviolet blocking rate and near-infrared block rate for glass coated with low-e, Low-e, and glass with heat-insulating films. The results showed that 1. The glass made with the nano-tungsten oxide coating has an infrared block rate of 91%. It also blocks ultraviolet light at 91%. 2. Low-e Glass has an infrared and ultraviolet blocking rate of 62%, respectively. 3. The infrared-blocking rate for the glass with heatinsulating film is 59%. It has a 99.7% ultraviolet blocking rate. 4. Hollow tempered glasses have an infrared-blocking rate of 34.2%. UV blocking is at 23.5%. 5. The infrared blocking percentage for single-sided glass is 12.4%. UV blocking is 13.5%.
These data show that single-sided windows with nano-tungsten-oxide coatings have the best results in blocking infrared and ultraviolet radiation. On the other hand, single-sided ones with thermal insulation films or nano-tungsten as well as single-sided are better at blocking the latter. Double-sided, coated glass. But industry insiders state that UV blockers are harmful because of their bactericidal properties. This is why normal people use the sun to take pictures. We all know that sunlight provides energy for all living things on Earth. However, infrared light and ultraviolet rays in sunlight are not good for your body. The scientifically most important permeability ratio is around 10%. It is therefore the best choice for both energy conservation and human health.
To put it another way, the tungstenoxy transparent insulation material has two major problems that have to be resolved immediately for building energy-saving windows: 1. It is important to have high transparency. This means it has high visible light transmittance, and that it meets the lighting requirements. It is also a good barrier for the infrared spectrum. This is a high barrier that blocks the radiation of the sun. It also meets energy efficiency requirements.
Additionally, the tungstenoxide transparency heat insulating is an environment-friendly, water-based material. To enjoy the cooling effect of warm winter or cool summer, it only requires a thin paint of several micrometers. The insulation material also offers safety features such as privacy protection, security, anti-aging and stain resistance. . Also, this type of insulation is made from tungsten-bronze, ITO/ATO, FTO and others.
Tungsten oxide insulation is not a product made from “black technology,” but is rather the product of scientific technological innovation. Such transparent insulation materials, such as Tungsten Oxide Insulation, will undoubtedly receive greater attention today with the advocacy for energy saving and emission reduction and taking the path to sustainable development.
