Description
The aim of the experiment was to determine the adhesive properties of biological powders by visualizing latent traces of papillary line patterns on glass, plastic and metal surfaces.Biological powders of guar and xanthan gum, cinnamon, turmeric, paprika, onion, banana, blackcurrant, agar, spirulina and chlorella were used to visualize the feet. Powders with the degree of granularity offered by the manufacturers were used to visualize the traces of experimentally left papillary line patterns. After visualizing the traces of latent papillary line patterns left experimentally, the adhesive properties of the powders were divided into three categories: A - good adhesive properties (good reflection of the trace); B – average adhesive properties (reflection of the foot is not pronounced); C – weak adhesive properties (the powder practically does not color the foot), while if the color of the powder did not contrast or coincide with the color of the object receiving the foot, then the designation N was applied – the powder was not used because of its color, because it does not contrast with the color of the object. The results of the experiment were reflected in a table indicating the assessment of the adhesive properties of the powders, with a photo attached.
