Problems solved by technology

However, the chlorine salt deicing agents currently used are not environmentally friendly, and cause serious corrosion damage to buildings and road surfaces. After the industrial salt in the deicing agent melts, it will pollute groundwater and even affect the safety of drinking water.
Salt can degrade in the soil for up to 15 years, so the negative impact of deicing agents on the environment will last for a long time, and some environmentally friendly desiccants are very expensive to produce and are not suitable for large-scale promotion

Abstract

The present invention relates to a low production cost environmental protection type snow removing agent, which comprises the following c omponents, by weight, 50-90 parts of calcium chloride, 5-20 parts of sodium tetraborate, 10-20 parts of urea, 5-15 parts of sodium nitrite, and 3-8 parts of sodium sulfate peroxide. According to the present invention, the snow removing agent comprises calcium chloride, sodium tetraborate, urea, sodium nitrite, and sodium sulfate peroxide, and has characteristics of easily available raw material and low production cost, wherein the snow removing agent reacts with snow after the snow removing agent is combined with the snow, such that the snow melts so as to prevent freezing. The low production cost environmental protection type snow removing agent has the following characteristics that the snow removing agent does not provide damage for ground and plants; the snow removing agent is applicable for ground snow removing of areas with a temperature of more than -20 DEG C, wherein a use amount is 20-40 g / m<2>, a maintaining time is about 10 days at the area with a temperature of more than -15 DEG C, and a maintaining time is 6 days at the area with a temperature of less than -15 DEG C; and the snow removing agent is suitable for large scale mechanized throwing operations, and has advantages of no damage on subgrade and road surfaces, and maintenance cost reducing.

Description

technical field [0001] The invention relates to a deicing agent, in particular to an environment-friendly deicing agent with low production cost. Background technique [0002] At present, deicing agents are generally required for the snow removal work after the heavy snow in winter in the north, because if the deicing agents are not sprinkled, traffic accidents will increase. Artificial snow removal is not only slow, but also affects traffic. At present, spraying deicing agent is the most timely and fastest way to ensure smooth traffic. However, the currently used chlorine salt deicing agents are not environmentally friendly, and cause serious corrosion damage to buildings and road surfaces. After the industrial salt in the deicing agent melts, it will pollute groundwater and even affect the safety of drinking water. Salt can degrade in the soil for up to 15 years, so the negative impact of deicing agents on the environment will last for a long time, and some environmental...
