For the industrial nozzles we know, the commonly used materials are 303 stainless steel, 304 stainless steel, 316 stainless steel, brass material, plastic material, alloy material, etc., most of them are determined according to the use environment, of course, and the customer's material. Under normal circumstances, we are based on the use of the product environment to choose specific materials, most may be in corrosion resistance, wear resistance and other aspects of the emphasis on consideration!
First of all, the nozzle itself, ultrasonic atomization nozzle air humidification nozzle is an aerodynamic atomization nozzle, belongs to the water-gas mixing atomization type, also known as the two-fluid atomization nozzle, but it is not a simple two-fluid atomization, the obvious difference is the use of ultrasonic generator to produce acoustic resonance, so as to obtain ultrafine atomization particles, Micron atomized particles (1-10 microns), its particles are definitely much finer than the 50 micron or so particles that come out of the conventional installation of atomizing nozzles, and the fog effect is dense, suitable for atomizing humidification and spray dust removal and so on!
As far as this nozzle is concerned, because the nozzle has a flow hole, it is necessary to consider wear-resistant, must be at least consider stainless steel, other such as brass is not wear-resistant, 304 stainless steel, and most of the peers are using 303 stainless steel, from the product performance, 304 is definitely better than 303, Mainly reflected in the corrosion resistance, whether it is applied to space humidification, or for micron level dry fog spray dust collection system, 304 material is not easy to rust, and 303 is relatively easy to rust, especially in the case of wet, slight corrosion, it looks very obvious, that is, the product is installed on the outside surface of the rust spot.
