1. Powder powder in the storage process if the absorption of moisture caking, you need to be placed in a cool well-ventilated place to dry not sun, crushed before use, if the agglomeration is more serious, can only be used for poisonous soil. 2. Wettable powder Take 1 part of wettable powder, add 200 parts of water, and put it in a glass. Shake well and wait for a certain period of time to observe the suspension. If the drug precipitates slowly, it indicates good suspension. If it absorbs moisture, it is not suitable for spraying. 3. If the EC is poorly maintained, the following three conditions may occur. First, agglomeration phenomenon such as emulsified oil has not flowed viscous liquid or has formed a soap-like solid, it proved that the solvent has been mostly volatile, the quality has changed, can not be used. The second is the long-term storage of emulsion precipitation phenomenon, the bottom of the bottle will have white crystals or turbid substances appear. If the cream bottle is immersed in warm water at 30-40°C, the crystals can be dissolved in about 30 minutes to return to a transparent liquid, indicating that the quality is good and can be used. If it does not dissolve, it indicates that the quality of the emulsifiable concentrate has changed and cannot be used. Thirdly, the emulsifying properties of emulsifiable concentrates were changed to 1 part of emulsifiable concentrate and 200 parts of water were added to the glass. After shaking for about half an hour, the emulsification was observed. If there is no slick in the upper layer, there is no sediment in the lower layer, and there is no obvious oil in the middle. It shows that the emulsifying performance is good; if there is emulsifiable concentrate on it and there is precipitation, there will be stratification after 10 minutes, indicating that the emulsion cannot be used.
