The application of nanomaterials in surface engineering is mostly to stabilize the nanoparticle dispersion in the organic medium. For example, the workpiece is ground and the antifriction material is dispersed in the lubricating oil in an appropriate manner. The ultrafine polishing liquid is nanometer SiO2, nanometer. Lubricants for nanoparticles such as Al2O3, nano-MoS2, nano-Cr2o3, and nano-diam...

Nano-zero-valent iron (nZVI) nanopowder is an iron particle with a particle size between 1 and 100 nm. Its specific surface area and reactivity are much larger than ordinary iron filings and iron powder. It can be directly injected into the heavily polluted area of the water environment to form an efficient in-situ reaction zone, which can control water pollution flexibly, efficiently and at low c...

The granular shape of titanium powder includes spherical, polygonal, sponge, and flake shapes. The granular shape is related to the method of preparing titanium powder. The requirements for titanium powder generally include three aspects, namely purity, particle size and granular shape. Titanium powder is divided into 4 grades. The size of 1000-50um is coarse powder, 50-10um is fine powder, 10-0.u...

A photocatalyst is also called photocatalysis. Simply, a photocatalytic material undergoes light irradiation and does not change itself but can promote other substances to undergo a chemical reaction. There are many examples of photocatalyst reactions around us. The most typical is The chlorophyll, which plays the most important role in photosynthesis of plants, is a photocatalyst. Photocatalysts ...

What exactly is a thermal battery? Thermal batteries are also called thermally activated reserve batteries. The single cell of the thermal battery is composed of a positive electrode (FeS iron-sulfur alloy), an electrolyte, and a heating sheet (iron powder). The main body of the heating sheet is iron powder, and its conductivity is relatively high. FeS iron sulfur is a semiconductor material, whic...

Nano oxides have many unique properties and have been widely used in textile fields such as antibacterial, deodorant, and ultraviolet protection. Similarly, nano-oxides have a positive effect on anti-wrinkle finishing. Nano-titanium dioxide or nano-silica is added to the traditional system to form nano-oxide anti-wrinkle finishing liquid through high-speed shearing, so that the fabric has anti-wri...

By mixing a small amount of nano silica into concrete, ultra-high strength and ultra-high durability concrete can be easily prepared. At present, a large number of research results have proved that nano SiO2 has a good modification effect on cement. The cement paste doped with nano silica has reduced fluidity, shortened setting time, and significantly improved early strength. Nano-doped nano silic...
