Storage and Transportation of Chemical Fertilizers Must Be "10 Preventions"
Pay attention to avoid the following ten points in the storage and transportation of chemical fertilizers: One against the open dump Fertilizers cannot be piled up in the open air. For example, when ammonium bicarbonate is placed outdoors at an air temperature of 20°C, the ammonia loss rate is 8.8% for 1 day, 48% for 5 days, and 74% for 10 days. Therefore, the fertilizer should be placed in a cool and monotonous place in the house. Two moisture-proof Nitramine loses moisture after “chemical waterâ€, and the superphosphate will form a hard block and become insoluble. Therefore, fertilizers are tightly packed with plastic or linoleum, and they are best avoided from being exposed to moisture. Three against heat The higher the temperature is, the more volatile and agglomerate the chemical fertilizer becomes (the worse the consolidation). Therefore, timely adjust the temperature of the storage house and maintain it below 30°C. When the temperature outside the room is low, open the doors and windows and lower the room temperature. Better not in the kitchen with heat. Four anti-volatile Ammonium bicarbonate is poorly consolidating and easily decomposes and volatilizes. When the temperature is higher than 20°C, it will decompose into ammonia gas, carbon dioxide and water and cause loss. Therefore, it is necessary to check whether the package is damaged, how to use it, and how much to use. Five fire prevention Ammonium nitrate, potassium nitrate, etc. are flammable and cannot be stored together with flammable materials such as kerosene, gasoline, straw, wood chips, etc., so as to avoid causing fire. Six explosions Ammonium nitrate, potassium nitrate, etc. are prone to explosion. If they are mixed with metal powders such as copper and iron, they can cause explosion accidents if they are rubbed. Therefore, after the hardening of these fertilizers, do not use metal objects and smash them with heavy objects. Seven anti-corrosion Superphosphate contains free acid, which has a corrosive effect on storage utensils and human skin. It should not be stored in direct contact or exposed to gold.
