MPa Spray

In addition, when the output of the paint to the nozzle, there is an instantaneous evaporation of some part of solvents included in the ink, which leads to additional dispersion of it. Due to the resulting kinetic energy of the drops move to paint the surface, and overcoming the resistance of air, brake, and gently lay down on the painted surface. Material heated to 60-100 degrees, is supplied to the nozzle under the pressure of 6.10 MPa. At coating, painting machines, without heating the material enters the nozzle at a temperature 18-23 degrees under pressure of 14 25 MPa. Airless paint without heating is used for priming and painting products medium and large size, as well as large surfaces on which to apply coatings to meet grade finishes 3-4. Method paint airless painting machines especially high-pressure effective at coloring your plane or boat-tailed and nepregoden for articles of complex shape as a consequence of sharp losses desc coating material, uneven coverage, the advent of sagging. The number and quality of the material sprayed on the pressure, size and angle of the hole painting nozzle, the viscosity of the material and its physical characteristics. Compared with pneumatic spray airless spray allows you to: dramatically reduce the loss-on paint fogging – reduce the amount of solvent at the possibility of spraying more viscous coatings – to increase productivity (especially when painting large areas). except of the possibility of staining the surface at several positions – in some cases reduce the complexity of the painting works expense of the possibility of coating of greater thickness – considerably reduce the fumes and the room improve the hygienic conditions of work in the shop, especially when there is insufficient ventilation. In contrast to the flare, which appeared in the work of a pneumatic spray gun, airless spray torch at spray paint sharply outlined forms and almost no explosions. Taken from the site
