According to media reports on June 21, the robotic arm on the core module of the China Space Station is currently the most intelligent, difficult, and complex space intelligent manufacturing system in China, and it is the most authentic restoration of a h

There are two types of external mold release agents and internal mold release agents. The materials used for the external mold release agent and the internal mold release agent are different, and there is a big difference in price.

Boron carbide, also known as black diamond, is an inorganic substance with a chemical formula of B₄C, usually gray-black micropowder. It is one of the three hardest materials known (after diamond and cubic boron nitride).

Chemically foamed cement is the use of chemical methods (chemical reactions) to generate gas to foam cement materials to form cellular porous materials. This foaming form and process are called chemically foamed cement.

Nanomaterials refer to materials that have at least one dimension in the nanometer size (1-100 nm) or are composed of them as basic units in a three-dimensional space, which is approximately equivalent to a scale of 10 to 1,000 atoms closely arranged toge

Aluminum nitride (AlN) is hexagonal, and pure AlN is blue-white, usually gray or off-white. Aluminum nitride ceramics have a series of excellent characteristics such as excellent thermal conductivity, reliable electrical insulation, low dielectric constan

Nitrides are binary compounds of nitrogen with fewer electronegative elements. Nitrides formed by the direct combination of transition elements and nitrogen are also called metallic nitrides.

PVC-SiO2 separators are also called wet-process PVC separators, which are mainly used in valve-controlled sealed lead-acid gel batteries. It has better oxidation resistance and chemical stability than polyethylene PE separator.

1. Explosive, flammable, corrosive, toxic, strong acid-base and radioactive dangerous items, such as detonators, gunpowder, firecrackers, gasoline, alcohol, kerosene, tung oil, lacquer, matches, pesticides, etc. are all listed in the chemical Chemical pro

Titanium carbide has the chemical formula TiC . Titanium carbide has steel gray crystals with metallic luster, which has thermal and electrical conductivity, and its electrical conductivity decreases with increasing temperature, so it exhibits metallicity
