A modification method of nano-samarium oxide MC nylon

MC nylon is a new type of engineering plastic, which is made of caprolactam as the main raw material by anion polymerization under atmospheric pressure. MC nylon is gradually replacing copper, aluminum, steel and other metal materials and is widely used in textile, rubber, petrochemical, steel rolling, mining machinery, automobile, elevator, crane and other industries. But compared with metal, MC nylon has some disadvantages such as lower strength, modulus and thermal deformation temperature, larger water absorption rate and poor [...]

Application of tantalum pentoxide

Tantalum pentoxide, also known as “tantalum anhydride”, is a white rhombic crystal. Its chemical properties are more stable, resistant to general acid and alkali, when heated by hydrogen chloride or hydrogen bromide erosion. The corresponding insoluble tantalate can be obtained by co-melting with the hydroxide of alkali metal or carbonate, which is hydrolyzed by washing with water to produce hydrated tantalum pentoxide precipitate. At present, the traditional high purity tantalum pentaoxide is prepared by the tantalum liquid in the [...]

Application of nanometer molybdenum trioxide

Compared with “massive” or several micron molybdenum trioxide, the catalytic activity of nanometer molybdenum trioxide is significantly improved, and its catalytic effect is several times or even ten times higher for some chemical reactions. The corrosion resistance and oxidation resistance of nano-mo trioxide are also higher than that of traditional mo trioxide. Other properties, such as optical and electrical properties, are still under investigation. In addition, nanometer molybdenum trioxide is the precursor of some materials. Such as molybdenum powder, [...]
