| 摘要： | Prewetting salt helps it work more effectively as a deicing agent for two reasons: First, wet salt clings to the road instead of bouncing off or being swept off by traffic. The result is that less salt is spread, saving money and minimizing the threat to the environment. Second, to be effective as a deicing agent, salt requires moisture. Moisture dissolves the salt, releasing heat and thereby melting the ice and snow, as well as breaking the ice-road bond. When temperatures drop below freezing there is no moisture on the road, and salt alone is ineffective. Prewetting the salt, however, ensures that there will be enough moisture to facilitate the melting process. Then, prewetted salt works faster and at lower temperature than does dry salt, with less waste. |
