Ammonium metatungstate may be applied for preparing a new type of transparent infrared thermal insulation nano material such as transparent heat insulation coatings of nano particle size cesium tungsten bronze. In this process, ammonium metatungstate particles are mainly used as near-infrared short-wave nano shielding materials. By taking the sprayed automobile glass as an example, a new environmentally friendly heat-insulating glass treatment method will be specifically introduced.

First of all, the car to be sprayed should be placed in a confined space with an air inlet and outlet system. The temperature is controlled at 20-35°C and the humidity is controlled below 80%. Before spraying, you should wash the glass and protect the car body, that is, protect the car surface from the place to be sprayed to ensure that it will not be contaminated when spraying. Then, the prepared spray material is poured into a watering can, and the spray parameters are adjusted according to the parameters, and then sprayed. After spraying, the surface is dried to a non-sticky standard, and then the protective layer is removed.
