Silicon Nitride Rings and Rods introduction
Featuring high density and abrasion resistance, fine silicon nitride ceramic is suitable material used for low pressure die casting. silicon nitride sealing pipe/stopper pipe has the most favorable properties of protectiveness, impermeability and excellent precision.
The life time of silicon nitride sealing pipe/stopper pipe can be used for many years if keeping regular maintenance. Otherwise, incorrect operation and less attention to a maintenance will reduce the life time.
Charcteristics of Silicon Nitride Rings Tube
Young's Modulus of Elasticity
Coefficient of Linear Thermal Expansion
Heat Shock Resistance
Maximum Available Temperature
Outstanding corrosion resistance to molten aluminum alloys and flux contamination free.
Oxidation rarely accurs at operating temperature(up to 800 C), which allows hi-cera to maintain stable performance for a long service life.
3.Thermal shock resistance
Superior thermal shock resistance allows hi-cera protection tubes to be inserted in molten aluminum directly with simple preheating.
The highest strength among ceramics allows a thin wall thickness.
Excellent wear resistance gives degassing rotor shafts a long service life at a high speed revolution.
Exceptional acid resistance against acids such as hydrochloric acid and sulfuric acid permits removal of sticking matter on the surface with such acids.
