百菌清是一种高效低毒的杀菌剂,对农作物有保护治疗作用,药效稳定,残效期长。对有机硫制剂所能防治的果树、蔬菜病害如霜霉病、白粉病、炭疽病、斑点病等都有效。还可以防治蚕体酵母病和僵病。此外,在皮革、油漆、电器的防霉应用上也有良好的效果。从1963年美国 DiamondAlkali 公司将该产品投放市场以来,百茵清产量不断增加,产品质量不断提高。目前国内工业上生产百茵清主要有两种方法:固定床生产工艺和复合床生产工艺。其中固定床生产工艺产量较小,生产能力受到限制。因此,国内开发了流化床与固定床相结合的复合床生产工艺。在复合床试车与生产期间,出现了反应床飞温的现象,严重的一次导致了固定床的列管被烧穿了数十根,我们对飞温原因进行了分析并提出了改进措施。较好地防止了 Chlorothalonil is a high efficiency and low toxicity fungicide, which has protective and therapeutic effects on crops and has stable efficacy and long residual period. Organic sulfur preparations can control the fruit trees, vegetable diseases such as downy mildew, powdery mildew, anthracnose, spot disease are valid. You can also prevent and cure silkworm yeast disease and stiff disease. In addition, leather, paint, electrical mildew applications also have good results. Since the American Diamond Alkali Company put the product on the market in 1963, the output of BaiYinQing keeps increasing, and the quality of the products keeps improving. At present, there are mainly two ways to produce 100 Yin Qing in the domestic industry: the fixed bed production process and the composite bed production process. One fixed bed production process less production capacity is limited. Therefore, the domestic development of a combination of fluidized bed and fixed bed composite bed production technology. During the trial run and production of the composite bed, the temperature of the reaction bed was so warm that a serious one led to the burning of dozens of pipes in the fixed bed. We analyzed the reason of the temperature and proposed the improvement measures. Better prevented
