you are: Colouring by pneumatic dispersion

Than expense of air on dispersion, the above its pressure there is more, the big there are paint losses. Hence, it is important to achieve good (full) dispersion of a paint, the maximum productivity at the minimum expense of air. In a spray of Crewe a design raspylitelnoj heads and throttle-valve presence allow easily and to regulate quickly air giving, smoothly to change the form of a torch and to find, thus, the best mode of dispersion, reducing paint losses.

In type sprays 0-31А the head with external mixture has a number of apertures for an additional exit of air which creates a veil in the form of a cone enveloping a paint. Such device reduces formation of a fog and paint loss.

The Raised viscosity of the paint and varnish materials applied to dispersion, also allows to reduce their losses. Optimum viscosity of this or that material is underlined usually in corresponding specifications and sometimes is practically specified in the course of work.

Kraskonagnetatelnye the tanks intended for a food of sprays by a paint, represent cylindrical steel vessels in capacity of 15-1 50 l with a demountable cover on which the safety valve is mounted, a manometre and a reducer serving for pressure decrease, air arriving in a tank. For prevention of subsidence of pigments the tank is supplied privodnoj or a manual mixer. Air arriving from the compressor, happens is polluted by traces of lubricant oils and contains a quantity of water which is condensed in air pipes. These impurity get to a paint and can spoil a covering, therefore they are necessary for deleting. For this purpose the oil-water separator, a representing steel tank with a demountable cover serves. In a tank there is a filter which consists of a ring and three felt linings absorbing water and oil.
