摘要

Very low percentages of Nalco-E-102 (0.05 to 0.15 %) were tested with flat nozzles of different sizes at low working pressures. Adding a every low percentage of Nalco-Trol to the spraying fluid reduced the driftable size to less than 200 microns (P). The (P) values were 60, 42, and 20 % for concentrations 0.0, 0.05 and 0.1 % of Nalco-Trol, respectively. The droplet size at (P) values were also decreased by increasing the nozzle size. The measured V.M.D. was checked from the flow number or the viscosity formula and gave very close results. To achieve a reasonable V.M.D. with less variation between the upper and lower limits of the spray spectrum, it was recommended to add a 0.05 to 0.1 % of Nalco-E102 and adjust the designed working pressure to give less percentage of the driftable size with high spraying performance.
