Exair No-Drip Air Atomizing Nozzles Conserve Liquids
Internal mix nozzles stop liquid flow when compressed air is shut off.
Exair 1/8 NPT no-drip internal mix air atomizing spray nozzle
Exair’s 1/8 NPT no-drip internal mix air atomizing spray nozzles are designed to mix liquid and air inside the nozzle to produce fine atomized liquids and stop liquid flow when compressed air is shut off to eliminate post-spray drips and conserve liquids. According to the company, when the compressed air supply is shut off, the no-drip nozzle positively seals off the flow of liquid, eliminating the possibility of drips. The nozzles are available in three different liquid patterns — narrow angle round, wide angle round and flat fan patterns. They are also available with 1/8, 1/4 and 1/2 NPT inlets with a variety of liquid flow values. They are for pressure-fed applications where precise liquid flow is needed. Internal mix nozzles can be used on liquids with a viscosity up to 300 cP.
Better adhesion, enhanced corrosion and blister resistance, and reduced coating-part interactions make pretreatment a must.
Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
Some that bears precious metals is, and there are a host of regulations to consider when recycling.
