Tungsten-containing near-infrared absorbent (powder, dispersion liquid) is ultra-fine nano-particles obtained by high-temperature sintering and hybrid extraction of various metal oxides such as tungsten, vanadium, tin, and antimony. It has the property of absorbing red and near-infrared rays.
Tungsten-containing near-infrared absorbers (powder, dispersion liquid) have an absorption peak at 1200-1700nm, an absorption rate of 95%, and an absorption rate of more than 90% at 950nm-2000nm. The liquid dispersed by this material,
Tungsten-containing near-infrared absorbers (powder, dispersion liquid) have good dispersibility, high transparency, low haze, and they are resistant to high temperature, non-oxidizing, non-degradable, and have good weather resistance.
Tungsten-containing near-infrared absorbers (powders, dispersions) can be used as an excellent functional material for heat shielding, light filtering, anti-counterfeiting, and heat absorption.
Tungsten-containing infrared absorber powder/tungsten-based infrared absorber powder is blue-black or dark blue powder, mainly including cesium tungsten bronze powder, tungsten gold vanadium oxide powder, tungsten vanadium tin antimony oxide powder. The disposable particle size is 30-40 nanometers, the specific surface area is generally 30-50M2/g, and the peak wave band is 1200-1700nm.
Tungsten-containing infrared absorber dispersion/tungsten-based infrared absorber dispersion is also divided into cesium tungsten bronze, tungsten gold vanadium oxide, tungsten vanadium tin antimony oxide, generally blue black liquid, is water-based with a solid content of about 20% For dispersion liquid, the main solvents are water, ethanol, isopropanol, ethyl acetate, methyl ethyl ketone, etc.; China Tungsten Intelligent Manufacturing Technology Co., Ltd. can customize and process according to customer requirements for oily dispersion liquid.
