Using a salt brine mix of 90 percent sodium chloride and 10 percent magnesium chloride during winter storms offers several benefits:
First, the combination of sodium chloride and magnesium chloride enhances the melting properties of the brine. Sodium chloride (common salt) is effective at melting ice, but its efficiency decreases at lower temperatures. Magnesium chloride, on the other hand, works at lower temperatures and helps to keep the brine effective even in colder conditions.
Second, the brine mixture adheres better to road surfaces compared to dry salt. This means it stays in place longer and provides more consistent ice-melting action. The liquid form of the brine allows it to spread more evenly and cover a larger area, which is particularly useful for pre-treating surfaces before a storm.
Additionally, using a brine mix can result in cost savings. The liquid brine can be applied more precisely, reducing the amount of salt needed and minimizing waste. This not only lowers material costs but also reduces the environmental impact by decreasing the amount of chlorides released into the environment.
Overall, the combination of sodium chloride and magnesium chloride in a brine mix provides a more effective and efficient solution for managing ice and snow during winter storms.
