Properties of Silicon Nitride Ceramic Nozzle

1. Good corrosion resistance

Silicon nitride spiral nozzle has good corrosion resistance, can directly spray acid, alkali and other chemicals, generally do not produce chemical reactions, can be applied to various liquid spraying and corrosive working environment.

2. Good wear resistance

Silicon nitride hardness is high, compared with metal or plastic nozzles, silicon nitride nozzle has better wear resistance, wear during use is very small, so the service life is long.

3. No rust or aging

Compared with metal nozzles, silicon nitride nozzle is not easy to rust during long term contact with water, and there is no need to consider maintenance problems in humid environments.

4. Good high temperature resistance

The silicon nitride nozzle has good high temperature resistance, can work continuouslly for a long time in the environment of higher than 1200℃, and has good thermal shock resistance, not easy to crack due to hot and cold alternately.

Applications of Si₃N₄ Nozzle

(1) Spray coating

In the automotive, shipbuilding industry, construction and other industries, silicon nitride ceramic nozzle can be used to form a film by spraying paint evenly onto the surface of the coated material. The quality and efficiency of the coating are high, and the waste of the coating can be reduced.

(2) Washing and cleaning

Silicon nitride ceramic nozzle can be used for washing and cleaning purpose, by spraying water or detergent at high pressure and high speed to the surface of the object, to remove stains and dirt.

(3) Cooling and humidification

Silicon nitride nozzles can be used for humidification or cooling by spraying water mist or steam onto the object surface or to the air.

(4) Mechanical processing

Silicon nitride nozzle can be used for sandblasting process, so that the surface of the workpiece to obtain cleanliness and a certain degree of roughness, increase the adhesion between the surface of the workpiece and the coating, extend the durability of the film, also eliminate the stress of the workpiece, improve its fatigue resistance.

(5) Fuel combustion

Silicon nitride nozzles can be used in combustion engineering to spit out gas or liquid fuel at a certain pressure, mix with air and ignite the mixed gas.
