Some people mistakenly believe that the winter weather is cold, the temperature is low, the fertilizer does not volatilize, and it is not much corrosive. actually not.
Ammonium bicarbonate, ammonia water, ammonium sulfate, etc. in nitrogen fertilizer are not non-volatile under low temperature conditions, but have a slower volatilization rate and less volatile amount than the summer and autumn high temperature seasons; ammonium nitrate and potassium fertilizer in nitrogen fertilizer Potassium nitrate, sodium nitrate, etc., although it is prone to combustion and explosion at high temperatures, it is also dangerous to store it in the kitchen or heating stove in winter; the corrosion of superphosphate does not have much to do with the temperature. Cloth bags, sacks, etc., if exposed to superphosphate, will be corroded, and the contents of the bag, such as seeds, salt, soda ash, etc. will deteriorate. When nitrogen oxides are volatilized, they will turn into moisture in the air, which will turn into ammonium chloride with strong corrosiveness. When the seeds are encountered, the embryos will lose their budding power. When they are exposed to food, they will be degraded. Products and irons can cause corrosion and peeling.
For the above reasons, storing fertilizer in the cold season also needs to be done:
Sealed and stored to prevent the evaporation of many nitrogen fertilizers, such as ammonium sulfate, ammonium bicarbonate, ammonium nitrate, etc., due to the extremely unstable nature, it is easy to decompose and volatilize during storage to reduce fertilizer efficiency. Therefore, such fertilizers should be stored in airtight plastic bags or other sealed and corrosion-resistant containers.
The nitrogen fertilizer in the waterproof and moisture-proof nitrogen fertilizer can dissolve in the water, and it is easy to agglomerate or lose water after being wet or wet. Therefore, during storage and storage, be sure to keep dry and prevent the bag from being broken. If the bag breaks, it begins to absorb moisture and agglomerate, which then dissolves the drip and causes damage.
Note that fire-resistant ammonium nitrate fertilizer is flammable and flammable. It is easily oxidized at high temperatures and burns or explodes. Therefore, to store such fertilizers, pay attention to fire prevention, do not approach the stove, and do not store with flammable materials. Fertilizers that can chemically react with each other are preferably stored separately.
Anti-pollution ammonia fertilizer can not be placed in the bedroom or hall, so as to avoid the volatile ammonia gas irritating the eyes, nose and respiratory tract, which is harmful to health.
Anti-corrosion fertilizers are more or less corrosive, and must be strictly selected for storage containers. Carbon ammonia, calcium superphosphate, etc., should never be stored in cloth bags, sacks and paper bags, and should be stored in plastic bags or porcelain jars. All kinds of chemical fertilizers cannot be stored in a house with seeds, grain and oil, and agricultural tools.
Mutrade car parking tower, ATP series are a type of automatic tower parking system, that is made of a steel structure and can store 20 to 70 cars at multilevel parking racks by using high speed lifting system, to extremely maximize the usage of limited land in downtown and simplify the experience of car parking. By swiping IC card or inputting the space number on operation panel, as well as shared with information of parking management system, the desired platform will move to entrance level of the parking tower automatically and quickly.
