Abstract

In this research, the effect of cold plasma treatment on coating ability of palm trees for bark cutting pattern was evaluated. For this purpose, the date palm trunk with an average diameter of 60 cm was selected and discs with a thickness of 5 cm were prepared from the height equal to the pollen chest. Then, healthy and flawless samples with dimensions of 10 × 10 cm were prepared from three points: close to the bark, between bark and center of the trunk and near the center of the trunk. Before the tests, the surface of the samples was sanded and then conditioned. After cold plasma treatment and then coating with acrylic water-based paint, surface roughness, wettability and adhesion of coating were done on samples. Based on the results, the highest base density and the lowest surface roughness were observed near the center of the trunk. The results also showed that plasma treatment increases the surface wettability. According to the inverse relationship between surface roughness and adhesion, before and after plasma treatment, the highest and lowest tensile adhesions were observed near the center of the trunk and near the skin, respectively. It can be concluded that the use of plasma treatment improves the adhesion of the palm tissue.
