Transportation
Our factory provides a 1 year warranty for compliance with the requirements for storing the substance under recommended conditions, with proper transportation and storage.
Since ammonium sulfate requires special attention during transportation, you need to treat its packaging with special care. In general, GOSTs have been developed for its packaging, and of course we try to comply with them. Therefore, in our chemical plant, the finished substance is packed in strong plastic bags, which in turn are tied with a double knot with a thread or even sealed. At the choice of the buyer, it is also possible to pack this substance in paper five - six - layer bags.
Receiving
Under laboratory conditions, the substance can be obtained by combining concentrated sulfuric acid and concentrated ammonia solution.
2NH3 + H2SO4 → (NH4) 2 SO4
In the chemical industry, the main methods for producing ammonium sulfate are:
The process of neutralizing sulfuric acid with synthetic ammonia;
Combining ammonia from coke oven gas with sulfuric acid;
Treatment of gypsum with solutions of ammonium carbonate;
Recycling of waste remaining after the production of caprolactam.
This is certainly not a complete list, there are other production methods, for example, from gases produced at a power plant, which also applies to the activities of sulfuric acid plants. Namely, this happens as follows: gaseous ammonia is introduced into hot gases, which binds sulfur oxides in the gas into various ammonium salts, including ammonium sulfate.
Application
As a fertilizer in any climatic conditions, the most favorable application of ammonium sulfate in the spring, since a large amount of nitrogen in its composition, stimulates the growth and development of crops. Ammonium nitrogen of ammonium sulfate is easily absorbed by plants. Sulfur is essential for the nutrition of all crops, as it is part of some essential amino acids synthesized by plants.
Mineral fertilizers based on this substance are quite universal and are suitable for almost all types of soils, and its effectiveness has been proven when used in all climatic zones. The only thing that is not recommended is the use of ammonium sulfate on acidic soils, as this can lead to acidification.
This fertilizer can be used both on farmland and in the home garden, not to mention the personal plot. All this is due to the fact that the components of the substance are in the form of ions, which, in turn, allows you to achieve maximum assimilation by plants.
So, we figured out that ammonium sulfate can serve as an excellent mineral fertilizer, but which crops can be processed with it? The list is quite wide: potatoes and other vegetables, radish, corn, sunflower, sorrel, radish, rapeseed, wheat, buckwheat.
Precautions for handling the substance
Ammonium sulfate is now recognized as safe for humans and is sometimes even used as a food additive in Russia, Ukraine and the EU countries. Sometimes, it is also used as a salt substitute, in this case, ammonium sulfate is spoken of as a food additive E517. Well, of course, there are permissible doses everywhere, and here, if after contact with a substance, swallowing it or getting on the skin and eyes, you feel any irritation, you should consult a doctor.
Storage conditions in a closed warehouse, where the product will be protected from direct contact with water or exposure to high humidity.
