一、前言目前我国农药乳剂生产中所沿用的传统工艺,在计量上存在严重缺陷,在配制中带有盲目性和偶然性,配制精度和一次合格率都低,影响了产品质量和生产成本。同时,由于接触毒性物质严重影响到操作工人的身体健康。因此,我们研制成功用计算机来控制农药乳剂的配制。经过几个月的生产运行表明,其控制功能稳定、可靠、抗干扰能力强。且系统通用性 I. Introduction At present, the traditional techniques used in the production of pesticides and emulsions in China have serious defects in measurement. They are both blind and contingent in formulation, and the preparation accuracy and the first pass rate are both low, affecting product quality and production cost. In the meantime, exposure to toxic substances seriously affects the health of operating workers. Therefore, we have successfully developed a computer to control the formulation of pesticide emulsions. After several months of production operation shows that the control function is stable, reliable, anti-interference ability. And system versatility
