Description
Изобретение относитс к химической промышленности , к составам, примен емым дл ликвидации снежно-лед ных образований.The invention relates to the chemical industry, to compositions used to eliminate snow-ice formations.
Известен состав, примен емый дл предотвращени смерзани сыпучих материалов, примерзаний различных материалов к поверхности , смерзаний снега на дорогах, содержащий хлористый кальций, хлористый натрий и другие соединени . Указанный состав не исключает коррозии.A known composition used to prevent freezing of bulk materials, freezing of various materials to the surface, freezing of snow on roads, containing calcium chloride, sodium chloride and other compounds. The specified composition does not exclude corrosion.
Цель изобретени - создание антиобледенител , исключающего коррозионную агрессивность . Это достигаетс тем, что в состав антиобледенител ввод т нитрит-нитрат кальци в количестве 2-40%.The purpose of the invention is the creation of an anti-icing agent that excludes corrosion aggressiveness. This is achieved by introducing calcium nitrite-nitrate in the amount of 2-40% into the anti-icing agent.
Состав антиобледенител следующий (в %): Нитрит-нитрат кальци 2-40The composition of the anti-icer is as follows (in%): Calcium nitrate-nitrate 2-40
Хлористый кальций или егоCalcium chloride or his
смесь с хлористым натрием 98-60a mixture with sodium chloride 98-60
Антиобледенитель готов т следующим образом .The defroster is prepared as follows.
Плав хлористого кальци или его смесь с хлористым натрием упаривают до концентрации 68% при температуре 160-180°С и подают в количестве 700 кг в пересчете на 100% или его смеси с NaCI в шнековый смеситель . Сюда же через дозирующее устройство загружают 300 кг твердого нитрит-нитратаThe calcium chloride melt or its mixture with sodium chloride is evaporated to a concentration of 68% at a temperature of 160-180 ° C and served in the amount of 700 kg in terms of 100% or its mixture with NaCl in a screw mixer. 300 kg of solid nitrite-nitrate are loaded through the dosing device here.
кальци в соотнощении 9:1 - 1 : 9 и перемещивают при температуре 150-170°С в течение 10 мин.calcium in the ratio 9: 1 - 1: 9 and move at a temperature of 150-170 ° C for 10 minutes.
Полученный плав кристаллизуют, сушат, охлаждают , готовый продукт упаковывают.The resulting melt is crystallized, dried, cooled, the finished product is packaged.
Антиобледенитель представл ет собой белую кристаллическую соль со светло-желтым оттенком, не довитую, неагрессивную, нетоксичную , практически не действующую на резину , кожу, хлопчатобумажные ткани, негорючую , обладающую свойствами ингибитора коррозии .The anti-icer is a white crystalline salt with a light yellow tinge, non-toxic, non-aggressive, non-toxic, practically non-active on rubber, leather, cotton fabrics, non-flammable, with corrosion inhibitor properties.
Предмет изобретени Subject invention
Антиобледенитель, содержащий хлористый кальций или его смесь с хлористым натрием, отличающийс тем, что, с целью предотвращени коррозии металлов, в него введен нитритнитрат кальци в количестве 2-40%.A deicer containing calcium chloride or its mixture with sodium chloride, characterized in that, in order to prevent metal corrosion, calcium nitrite is introduced into it in an amount of 2-40%.
