Determination of contact angle of polymer compositions for irrigators of cooling towers
摘要
The authors studied the contact angles of polymer compositions with a different content of a woodflour. It has been established that with increasing of concentrations of woodflour in the polymer composition, the contact angle decreases substantially, i.e. increases the hydrophilicity of the sprinkler which leads to slow movement of the water film, increasing its ability to spread. The results can be applied to improve the efficiency of cooling towers.
