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...

1. Application of Nano Iron Oxide in Decoration Materials In pigments, nano-iron oxide is also called transparent iron oxide (iron penetration). The so-called transparency does not specifically refer to the macroscopic transparency of the particles themselves, but refers to the dispersion of pigment particles in the organic phase to make a layer of paint film (or oil film). When light is irradiate...
