A ceramic spray nozzle is a zirconia flow-control part that directs liquid or air through a defined orifice. Applications include textile humidification, photovoltaic dust removal and air blowing, industrial coating and spraying, lubrication systems, and automated production-line cleaning equipment.

Core Advantages

Wear-Resistant Zirconia Inner Wall

The hard zirconia bore is suitable for continuous air or liquid flow, including streams carrying fine particles. Erosive wear develops slowly, reducing the rate at which the inner wall enlarges and changes the flow path.

Smooth Flow Surface for Repeated Fluid Passage

The finished zirconia bore has a smooth internal surface for air, coating media, humidification fluid, and cleaning liquid. Fewer rough machining marks means fewer places for residue to collect during continuous operation.

Corrosion-Free Flow Path with Mild Process Chemicals

Zirconia does not rust and tolerates common mild acid-alkali exposure better than unprotected steel. In humidification, coating, or cleaning systems, the flow path therefore avoids rust scale and corrosion pitting.

Customization

Nozzle Body

Round and irregular nozzle bodies produced to equipment drawings or confirmed samples.

Orifice Layout

Micro-hole, single-orifice, and multi-orifice structures produced to the required pattern.

Finishing

Inner-hole grinding, external contour machining, and locating or mounting surfaces produced to drawing.

Quality Control

Inspection starts with the nozzle flow path. The orifice entrance, outlet, and internal bore are viewed optically for chips, partial blockage, irregular edges, and visible defects that could alter the opening.

Body dimensions, locating faces, and mounting surfaces are measured separately from the flow opening. Optical methods are used for small internal features when a contact probe cannot reach them without risk of damage.

Every nozzle is inspected before shipment, including a cleanliness check for machining or packing debris in the orifice. Accepted quantity and inspection results are recorded against the production batch.
