Description
Summary:An experimental setup is developed to create a protective and decorative coating on the surface of building materials. Experimental study is conducted to create a protective coating using low-temperature plasma. The properties of the surface before and after the plasma treatment are investigated. At the increase of the plasma generator power (56-75 kW) the rate of the vitreous coating formation is significantly reduced, and the destruction of hydrous calcium silicates occurs at a lower depth (0.5-2.0 mm). In this case, the adhesive strength increases up to 2.34 MPa. At the increase of the exposure time at 56 kW (0.045 m/s melting rate) plasma generation power, the melt formation is observed not only at the surface but at depth of 0.7 mm and deeper. Also, a deep degradation of the material occurs and the adhesive strength decreases. The optimal heat flux density of plasma generator was established at 1.8-2.6 · 106 W/m2, which allows the achievement of the uniform layer formation on the wood surface that preserves its natural pattern visible.
