Impact Behaviour of Modified Biopolymer Droplet on Urea Surface
S. Yon Norasyikin, K. KuZilati, M. Zakaria and S. Suriati

Abstract:
The droplet impact behaviour provides the particle coating characterization during the coating process of controlled release fertiliser. To have a good coating uniformity around the urea granules, it is necessary to enhance the wettabitily properties between the coating material and urea surface. In this study, modified biopolymer is used as the coating material for the controlled release fertilizer. Various compositions of starch:urea:borate were prepared and evaluated for the wettability properties. The wettability properties measured are the maximum spreading diameter, dynamic contact angle and surface tension. The high speed Charged Couple Device (CCD) camera was used to capture the images of this droplet impact behaviour. From this analysis, it is indicated that a composition of starch:urea:borate (50:15:2.5) has the best wettability characteristic and thus are suitable to be used as a coating material.
