Process and apparatus for the superfine spraying of suspensions

摘要

Process and apparatus for the superfine spraying of suspensions which tend to form films and resinificate upon contact with air. An example of such suspensions are the suspensions for spraying high temperature lubricants formulated on a graphite basis with additions of alkylene polymerizates to a dispersion agent. The apparatus has a spray head with a nozzle opening, a die which can be pushed through the nozzle opening and a sieve insert. The suspension is sprayed in the most finely distributed form through an air atomizer nozzle by means of a pressure gas which is oversaturated or saturated with a liquid.
