Choosing the right deicer depends on the following factors.
Fusion ability. Compare this with 12 kg of ice per kg of pure sodium chloride at a temperature of -5°C.
Applicability: what is the effect on the freezing point drop, and at what temperature is the defrosting effect present?
Availability: is the deicer available directly and in sufficient quantities? Can it be easily stored in large quantities for several years?
Is the coating that must be treated against ice sensitive to corrosion?
Security: Should Drastic Security Measures Be Taken?
The environment: what is the environmental load of the de-icing agent? Remember that deicers are used intensively and in large quantities when winter hits.
The price: what about the quality/price ratio and the price in absolute terms?
Sodium chloride is the best choice because it is readily available anywhere. What’s more, it offers the best value for money. It is easy to transport, apply or spread and can be stored for a long time. Additionally, sodium chloride is not harmful to skin, clothing, or the environment.
The best result: first rake or remove the snow, then spread
Preventive spreading is the best option, as it avoids most problems. What’s more, it also allows you to make great savings. Thus, 1 kg of salt spread for preventive purposes corresponds to 5 kg of de-icing salt spread for curative purposes. If you have not managed to carry out the preventive salting in good time, start by evacuating the snow and then spread the de-icing salt or de-icing granules. This will give you the best result!
Sodium chloride, calcium chloride deicer, magnesium chloride, ethylene glycol, calcium magnesium acetate, sodium formate, and ureum are also used as de-icing agents. Calcium and magnesium chloride most often replace sodium chloride. These products work at low temperatures; however, they are hygroscopic, which makes it difficult to store them long-term. In addition, they are more corrosive and require safety precautions for use. Other de-icers are more expensive compared to sodium chloride. They will be applied to places that fear corrosion. In addition, they are more dangerous for the environment.
The most commonly used deicer will be sodium chloride because of the following:
- its availability
- its favorable price
- its efficient operation
- its safe use
- its minimal impact on the environment
With preventive spreading, great savings can be made. Thus, 1 kg of salt spread for preventive purposes corresponds to 5 kg of de-icing salt like in Ninja De-Icer for example spread for curative purposes.
