Nozzle Materials and Performance
The material of the nozzle's inner bore is crucial to performance. Choosing a nozzle coated with wear-resistant materials, such as tungsten carbide, keeps airflow constant, optimizing performance and reducing fuel consumption.
Advantages of Sandblasting Nozzles
- Operational Efficiency:
High quality nozzles improve process efficiency, reducing processing time and increasing productivity. Choosing the right nozzle can optimize abrasive consumption and improve cleaning results.
Versatility:
Available in different configurations and materials, they can be adapted to specific needs, offering customized solutions for every industrial sector.
Durability and Reliability:
Advanced materials such as tungsten carbide and boron carbide ensure long operating life, reducing replacement and maintenance costs, and ensuring consistent performance over time.
Nozzle Size and Air Consumption
The size of the nozzle is essential. A nozzle that is too small can prolong the blasting process, while a nozzle that is too large could reduce the pressure of the jet, compromising the quality of the blasting. Nozzle diameters generally vary between 5 and 12 millimeters. The smaller the millimeters in diameter, the lower the consumption of liters of air per minute, although this also depends on the pressure set on the compressor.
Nozzle Configurations
There are two main nozzle configurations:
- Straight Hole Nozzles:
They have a cylindrical internal hole, offering a more direct jet.
- Venturi Nozzles:
They have a smaller internal hole than the external hole, increasing the diameter of the sandblasting jet and promoting greater expansion of the jet.
FLANGED CYLINDRICAL NOZZLE
Metallurgical Industry:
Sandblasters, equipped with suitable nozzles, are essential for cleaning and preparing metal surfaces, removing rust, old paint and other impurities. This prepares metals for subsequent treatments such as painting or galvanizing.
Naval Sector:
In ship maintenance, sandblasters equipped with specific nozzles effectively remove marine scale, rust and old paint layers, preparing surfaces for new protective coatings.
Building Restoration:
In the restoration of historic buildings, sandblasters with delicate nozzles, such as ceramic ones, clean sensitive surfaces without damaging them, removing dirt, paint and air pollutants.
Automotive:
Sandblasters are used to clean automotive components, preparing surfaces for painting, coating and other finishing treatments, improving the adhesion and durability of coatings.
