    At aerosol dispersion the paint is in a metal hermetic cylinder under pressure to 2 кГ/см2 inert gas of freon-propellenta. By pressing the valve the paint under pressure is sprayed from a nozzle in diameter of 0,5 mm and forms a uniform thickness a covering. Dispersion occurs basically at the expense of evaporation propellenta. .

    As the spraying agent serve also szhizhennye gases - carbonic acid, nitrogen, etc.

    By means of a cylinder in capacity of 0,5 l can be painted nearby 2 м2 surfaces at a thickness of a film 12-14 microns. The distance from a cylinder to a painted surface should be 200-250 mm, width of a painting torch (at diameter of a nozzle of 0,5 mm) 50-65 mm. Before the use the paint in a cylinder should be shaken up well. For aerosol drawing paint and varnish materials on a basis alkidnyh and akrilovyh pitches, and also nitrovarnishes (enamels) on nizkovjazkom kolloksiline are most suitable.

    In a cylinder there should be an identical quantity of a paint and varnish material and freon. The automatic machine makes following operations for packing of aerosol cylinders: blowing off of cylinders by the compressed air, removal of air by freon blowing off, filling of a cylinder by a paint, zapressovka apertures and freon forcing. Aerosol drawing of paints especially effectively for podkraski defective places, and also for varnish drawing on wooden products.

    The Aerosol dusting of paint and varnish materials (varnishes and enamels) finds wide application in a life for colouring of various subjects: furniture, windows, doors, and also for podkraski cars, washing machines, refrigerators and other subjects.
