Analysis of Coatings based on Carbon-based Nanomaterials for Paint Industries-A Review

摘要

The spray painting is widely used in automobile industries, marines and navy, etc. Extensive development of research is going in Robotics for painting application. In which it gives the best quality and productivity but also reduces paint consumption during painting. This study will help in identifying the factors affecting the spray coating, environmental and chemical properties. The input factors which directly affects the output are spray gun design, nozzle sizes, the distance between substrate and gun, paint pressure flow, viscosity, flash point, pour point, robot speed, temperature, size of droplets, spray time, overspray. The output factors which we want to minimise are surface roughness, thickness, over-spray, the quantity of spray, operation time, heat transfer, corrosion, cracks, peeling and maximise the film adhesive, and the life span of the substrate. To enhance the quality of substrate, the carbon nanotubes (CNTs), like Multiwall Carbon Nanotubes (MWCNTs), are infused in paint by ultrasonication and magnetic stirrer process while preparing the nanopaint. The nanopaint has mechanical, thermal, electrical, chemical and physical properties. Nanopaint acts as a coolant, anti-corrosion, self-healing, and has less viscosity in nature with high young’s modulus. The formation of pores, debris and layers are very less in robot nanospray painting.
