Cs0.33WO3 nanoparticles may be used to prepare thermal insulation coating, which is a new barrier type ding material. Experts say the coating can be used in conjunction with reflective type coatings. Before we have already what is a barrier type coating. Today, let's look at what is a reflective type coating?

It is well known that the wavelength of solar radiant energy that can be received on the earth is mainly distributed in the range of 250-5000nm, and the solar thermal radiation can be divided into four parts according to the wavelength. From the spectral distribution of solar radiation, it is known that the visible light region and the near-infrared light region (380-2500nm) concentrate 90% of the solar radiation energy. In this wavelength range, the higher the reflectance, the better the heat insulation effect. The coating has three responses to incident light: reflection, absorption, and transmission. Reflective type coating is mainly a strong reflection of near-infrared energy. With such ding, the reflective coating can even be used for military purposes. It can avoid infrared detection equipment and make the target suitable for the surrounding environment, thus achieving the hidden effect.
