Paper Title:
The Preparations and Characterization of Water-Based TiO2 Nano-Coating
  Abstract

This study proposes a new method—the ultrasonic vibration-assisted arc-submerged nanofluid synthesis system (VANSS). This method prepares for water-based TiO2 woodenware nano-coating and applies the nano-coating to medium density fiberboard (MDF) to measure the characteristics of the coatings on the woodenwares. For VANSS, water-based coating serves as dielectric fluid and anodes, while cathode electrodes use titanium rods (editor’s note: please check carefully and consider revising the above sentence. I’m confused by the multiple use of ‘and’ in this case). Electrodes soon vaporize under the influence of a high-temperature plasma arc and instantly condense into nanoparticles under the cool effect of low-temperature dielectric fluid to form Ti nano-coating with good suspension. Placed for two weeks, Ti nano-coating has transformed into TiO2 nano-coating. TiO2 nano-coating is applied to MDF to compare the coating with and without the addition of TiO2 nanoparticles. The results show that TiO2 nanoparticles have an average particle size of 20 nm. For the coating properties test, the results show that lightness rises from 49.7 to 69.32, increasing 39.5 % after the coating is added to the TiO2 nanoparticles. Chroma lowers from 37.1 to 33.3, decreasing 11.3 % after the coating is added to the TiO2 nanoparticles. However, hue difference is within 3 %, having little influence on vision. Adhesion enhances from 1B to 5B, increasing 4 grades when the aqueous polyurethane, AE-418, is added to the TiO2 nanoparticles; solvent resistance elevates from 46.3 % to 56.8 %, increasing 10.5 % after the coating is added to the TiO2 nanoparticles.
