Description

Известно введение мочевины в аммиачную селитрз или в аммиачно-селитренные взрывчатые вещества путем смешени  ее с сухим готовым продуктом, с целью улучшени  агрохимических свойств селитры и улучшени  свойств взрывчатых веш,еств.The introduction of urea into ammonium nitrate or into ammonium nitrate explosives is known by mixing it with a dry finished product in order to improve the agrochemical properties of nitrate and improve the properties of explosive substances.

Предлагаетс  вводить мочевину в селитренный раствор или плав, с целью ингибировани  термического разложени  аммиачной селитры в процессе выпаривани  и кристаллизации ее. Мочевину ввод т в количестве 0,1-1,0% от веса аммиачной селитры.It is proposed to introduce urea into the nitrate solution or melt in order to inhibit the thermal decomposition of ammonium nitrate in the process of evaporation and its crystallization. Urea is introduced in an amount of 0.1-1.0% by weight of ammonium nitrate.

Введение мочевины повышает термостойкость селитры, что дает возможность безопасно проводить технологический процесс получени  селитры при температзфах значительно превосход щих 150-160° и тем самым рационализировать процесс производства перейти на непрерывный способ ее получени  с максимальным использованием теплоты нейтрализации дл  выпарки растворов.The introduction of urea increases the thermal stability of nitrate, which makes it possible to safely conduct the technological process of producing nitrate at temperatures significantly higher than 150-160 ° and thereby rationalize the production process to switch to a continuous method of its production with maximum use of neutralization heat for evaporation of solutions.

Стабилизированна  мочевиной селитра не разлагаетс  даже при 225° в то врем , как чиста  селитра начинает заметно разлагатьс  при 175°.Urea-stabilized nitrate does not decompose even at 225 ° while pure nitrate begins to decompose noticeably at 175 °.

Разложение стабилизированной селитры начинаетс  при температуре 250°, но скорость разложени  в 20 раз меньше скорости разложени  чистой селитры.The decomposition of stabilized nitrate begins at a temperature of 250 °, but the decomposition rate is 20 times less than the decomposition rate of pure nitrate.

Предлагаемый способ получени  аммиачной селитры устран ет возможность пожаров и взрывов селитры при производстве, хранении и перевозках ее.The proposed method for producing ammonium nitrate eliminates the possibility of fires and explosions of nitrate in the manufacture, storage and transportation of it.
