the Most widespread method of colouring is a dispersion of paint and varnish materials by the compressed air. This method it is possible to put almost all kinds of paint and varnish materials on products of any configuration and any sizes. Colouring by dispersion in 4-1 times proizvoditelnee colourings by a brush. A lack В»pneumatic dispersion are big poter materials on tumanoobrazovanie (20-50%), the considerable expense of solvents, danger in the fire relation and toxicity. Therefore specially isolated premises are necessary for colouring by dispersion - the chambers equipped with ventilation for clearing and an extract of polluted air. ремонт пластиковых окон

Installations for colouring by pneumatic dispersion consist of the compressor, an oil separator for clearing of submitted compressed air, kraskonagnetatelnogo a tank (in some sprays the paint can move also from glasses) and kraskoraspylitelja - a spray. The action principle kraskoraspylitelej consists in the following. аренда мерседеса дорогой магазин .

The Paint and compressed air arrive on two channels - to the tubes having the general axis; on an internal tube - to a material nozzle the paint, on an external tube - to an air nozzle - compressed air arrives. At an exit from a nozzle the paint swims with the current compressed air which, extending, breaks it into small drops and carries away behind itself. At hit on a painted surface of a drop merge, forming an equal coat layer. Райдеры MTD

Kraskoraspyliteli can be a high pressure if pressure of air at dispersion makes from 2,5 to 5,5 РєР“/СЃРј2 or low air with pressure to 2,5 РєР“/СЃРј2. In a machine engineering industry high pressure sprays as sprays of low pressure do not provide qualitative colouring are applied to colouring.

Mixing of air with a paint can be carried out or out of raspylitelnoj heads of an atomizer or in it. Mixing out of heads (external) facilitates dispergirovanie painting structures that allows to receive better quality coverings. Kraskoraspyliteli with internal mixing are high-efficiency, but high quality of colouring do not provide.
