Will fertilizers volatilize in winter?
Many people think that chemical fertilizers will not evaporate when the temperature in winter is low. Is this really the case?
Ammonium bicarbonate, ammonia water, ammonium sulfate, etc. in nitrogen fertilizers are not non-volatile under low temperature conditions, but have a slower volatilization rate and less volatility than the high temperature season in summer and autumn. Ammonium nitrate in nitrogen fertilizer, potassium nitrate and sodium nitrate in potassium fertilizer are prone to combustion and explosion at high temperatures, but if stored in the kitchen or near a heating stove in winter, there is also great danger. The corrosivity of superphosphate has little to do with the temperature. Cloth bags, sacks, etc. will be corroded whenever they come into contact with superphosphate, and the contents of the bags such as seeds, salt, soda ash, etc. will deteriorate. When nitrogen fertilizer volatilizes, it will be converted into highly corrosive ammonium hydroxide when it encounters water vapor in the air. Seeds will lose their germination ability when they encounter seeds, they will deteriorate when they encounter grain, and they will fail when they encounter pesticides. Iron can cause corrosion and spalling.
Therefore, in the cold winter, chemical fertilizers will also volatilize. Do not ignore this during storage.

â… Product Composition: polydadmac
â…¡ Product Properties
The appearance of this product is colorless to pale yellow viscous liquid. It is soluble in water. It has goodhydrolyticstability and high adaptability to PH value changes. It`s safe and non-toxic. Its freezing point is about -2.8℃, specific gravity is about 1.04/cm3 and decomposition temperature is 280-300℃. It`s polymeride AKD maturing agent of high charge density. Emulsion provides strong cationic component promotive and protective agent and promotes curing effect. This product is added directly into the synthesis process of intermediates or added a certain ratio in emulsion. This product can be added more in the papermaking system with heavier anionic trash, as the pulp potential equilibrium to play a dual role of sizing enhancement and forcing ripening.
III. Quality indicators;
Appearance: colorless to faint yellow thick liquid Solid content: 40±1%
PH value: 4.0~7.0 viscosity (mpa.s, 25℃): 7000-12000
IV. Application:
This product is applied in alkaline sizing system of AKD (Alkyl Ketene Dimer) to restrict largely the hydrolysis and migration aptitude of AKD. [The third generation" AKD is mainly used for the making of multipurpose duplicating paper filled by precipitated calcium carbonate. 60% cationic polymer can adhere to the fiber after the paper containing cationic polymer being reused, by which enhance hydrophobicity of the paper. Added to waste paper deinking agent, its cationic hydrophilic group adheres to ink particles easily, especially for hydrophobic aniline ink. After flotation, the whiteness of pulp increased. This product is also applied as cationic surfactant in pitch control agent for pulping.
