Spray ceramic nozzle
Alumina ceramics have better conductivity, higher mechanical strength and high temperature resistance. As a welding nozzle made of alumina ceramics, it has excellent high temperature resistance, high melting point, and no decline in mechanical properties. It can be used at high temperatures without affecting product performance or bursting. Good corrosion resistance, regardless of strong acid (except hydrofluoric acid), strong alkali (except hot alkali), inorganic organic salts and other conditions will not be affected.
