As a photocatalyst, WO3-TiO2 composite film is an emerging binary semiconductor composite material that can transport and separate photo-generated carriers between semiconductors with different energy levels, prolong the carrier lifetime, thereby improving quantum efficiency.

The photocatalysis of WO3-ZnO composite film is attracting much attention. According to the experts, WO3 is an important non-toxic semiconductor material with a narrow band gap (2.4-2.8eV) that can be used as a catalyst in the photocatalytic reaction for the catalytic degradation of organic substances in sewage. So, the preparation of WO3-ZnO composite film has become a major research hotspot, and its photocatalytic performance has paid much attention.

WO3 is a photochromic material, so WO3-TiO2-ZnO composite film is also a photochromic material with excellent photochromic properties. Well, do you know how to prepare WO3-TiO2-ZnO composite film?

ZnO-WO3 composite film is a composite thin film inlaid with ZnO nanocrystals. More specifically, the composite film adopts amorphous WO3 as a matrix, and ZnO nanocrystals are uniformly distributed in the amorphous tungsten oxide. Some experts have prepared ZnO-WO3 composite film on aluminum foil by sol-gel method, and its modification has been carried out with activated carbon. Taking methyl orange aqueous as simulated organic pollutant, photocatalytic degradation performance of ZnO-WO3 films is studied.

Yellow tungsten oxide is applied as a cement-based absorbing material because it has certain shielding properties against gamma rays. Well, what is the shielding performance of yellow tungsten oxide against gamma rays? Some experts used tungsten oxide powder as a fine aggregate to prepare a sample of φ10.5cm x 6cm cylindrical cement-based materials, and tested the shielding performance of the sample against gamma rays through an experimental system composed of a PTW UNDOS standard meter and ~ (60) Co, ~ (137) Cs sources.

Tungsten carbide cutter is specially designed with an upper cutter and a lower cutter for applying to mask making machine. According to the experts, the quality of tungsten carbide upper and lower cutters is affected by many factors. Wherein, the change of various process parameters during the sintering process has a great impact on the quality of the cutter. And the performance of cutter is determined by the materials such as the binder and the base material. Besides, the cleanliness of the particle surface and particle size also affect cutter’s performance.

Tungsten carbide cutter has the properties of high hardness, high strength, high toughness and high heat resistance (thermal stability), so it is suitable for applying to mask machine to produce cup-type masks, non-woven flat masks, and N95 masks, etc.

Tungsten carbide scraper is an important part of mask machine to fabricate surgical masks, N95 masks and other protective masks. Such a high-precision scraper can effectively clean the scraps generated by the mask machine during cutting process without polluting the environment.

Tungsten carbide blade is widely applied in mask machine such as cup mask machine, non-woven flat mask machine, N95 mask machine, 3M9001/ 9002 folding mask machine, duckbill mask machine, and stereo dust mask machine, etc.

Medical tungsten alloy radiation shielding door is a high-density tungsten alloy radiation shielding door. It has been reported that the density of a raw material will affect the property of the prepared radiation shielding parts. Higher density means better ray absorption and radiation shielding ability.
