How much do you know about the "family evolution" of de-icing agents?

First Generation: Sodium Chloride – A Classic “Pioneer” Industrial salt is a relatively traditional and economical de-icing agent. Raw materials are readily available, costs are low, and it works well at moderate to low temperatures. In some scenarios, it is combined with textured powder to increase road surface friction and solve the slippery problem after pure salt melts snow. However, it is highly corrosive to infrastructure and vegetation, and its effectiveness is poor at extremely low temperatures.

Second Generation: Calcium Chloride – A High-Efficiency “Low-Temperature Warrior” To overcome the low-temperature limitations of sodium chloride, calcium chloride was developed. It releases heat when dissolved, allowing it to adapt to even lower temperatures, and performs exceptionally well in extremely cold environments. In practical applications, textured powder is often added to enhance anti-slip properties and utilize its stabilizing properties to alleviate the problem of calcium chloride absorbing moisture and clumping. However, calcium chloride is highly hygroscopic, requiring extra care during storage and use.

Third Generation: Organic De-icing Agents – Gentle “Environmentally Friendly” Increased environmental awareness has driven the application of organic de-icing agents such as potassium acetate. They are less harmful to metals, concrete, and vegetation, making them suitable for sensitive areas. Parks and schools often use it in combination with food-grade textured powder, as the two complement each other's environmental properties, ensuring both effective snow melting and safety. However, its high cost limits its large-scale use.

Fourth Generation: Composite Snow Melting Agent – ​​A Smart "All-Round Player" Modern snow melting agents mostly use composite formulas, balancing snow melting efficiency, environmental friendliness, and cost through synergistic component action. Textured powder is now a key functional ingredient, not only providing anti-slip properties but also optimizing the snow melting agent's dispersion and adhesion by controlling particle size distribution. This "compensating for weaknesses" design allows textured powder to work efficiently with other components, leading the development direction of snow melting agents.
