Definitions

• the invention relates to a plant and a method for realizing nanomaterial coatings on surfaces of objects, in particular, lighting apparatuses and lighting apparatuses realized with said method.
• FIG. 13 shows an axonometric view of a projector treated with a nanomaterial coating
• FIG. 15 shows an axonometric view of a ceiling light treated with a nanomaterial coating
• a plant indicated as a whole with reference numeral 100 and adapted to realize the steps of the process described above is visible in a side view in Figure 2 and in a top view in Figure 3.
• the plasma treatment and the plasma cleaning and activation create the best conditions for the subsequent sedimentation of a coating on surfaces made of plastic material, metal, aluminum or glass .
• Plasma micro-cleaning also removes the smallest particles of dust which tenaciously sediment on the surface of the plastic materials due to the additives .
• the plasma induces a reaction which determines the complete detachment of the particles from the surface. Thereby, waste during the coating processes is significantly reduced.
• the chemical-physical reaction at the nanometric level allows obtaining high-quality surfaces with the highest degree of definition.
• an angle of contact Q i.e., a chemical-physical quantity defined by the angle formed by the intersection of a liquid- vapor interface with a liquid-solid interface or, less conventionally, a liquid-liquid interface, may be highlighted.
• T1O2 One of the properties of the T1O2 is the increase in the hydrophilicity of the surface if activated by means of light radiation.
• This speed regulation allows a homogeneity of the plasma surface treatment based on the size and type of the material of the support to be treated.
• the station 10 also comprises a sensor which detects the start and the end of the inserted object so as to allow a reduction in consumption, in consideration of the fact that the plasma head 12 is activated only at the passage of a piece to be treated.
• the pre-heating preferably occurs by means of IR 24 infrared lamps.
• the pressure of the pump is adjustable.
• the nanomaterial also has a biocide component, including preferably Ag, which gives antibacterial properties .
