De-icing agents are specifically designed for winter road de-icing, rapidly removing ice and snow through multiple mechanisms—lowering the freezing point, penetrating the ice–snow layer, and inhibiting refreezing. Their snow-melting performance exceeds 110% of that of sodium chloride and complies with the GB/T 23851 standard.

De-icing Agent

Product Overview

This environmentally friendly, high-efficiency de-icing agent is a specialized snow-melting and ice-removal product designed specifically for clearing roads of ice and snow during winter. Relying on multiple mechanisms—lowering the freezing point, penetrating ice and snow layers, and inhibiting refreezing—it can rapidly break up ice and snow on road surfaces, effectively ensuring safe and efficient traffic flow in winter. The product is manufactured in strict compliance with industry standards such as GB/T 23851 “Road De-icing and Snow-Melting Agents,” offering advantages including rapid snow melting, low corrosivity, and environmental safety. It is widely applicable to various winter de-icing scenarios, including urban roads, highways, and airport runways.

Technical Principle

The de-icing mechanism operates on three core levels: First, the freezing-point depression effect—when the de-icing agent dissolves in the thin water layer on ice and snow, it forms a special solution whose freezing point is far below that of pure water, enabling solid ice to melt smoothly even at temperatures below 0°C. This is the fundamental principle behind the product’s snow-melting and ice-removal capabilities. Second, penetration and interfacial separation—the de-icing agent exhibits excellent wettability and penetrability, quickly infiltrating the contact interface between ice/snow and the road surface, breaking the adhesive bond between them and making previously firmly attached ice and snow much easier to remove. This is a key factor in enhancing de-icing efficiency. Finally, long-term prevention of refreezing—some high-performance formulations incorporate sustained-release components that effectively prevent melted snowwater from refreezing in low-temperature conditions, thereby extending the duration of the de-icing effect.

Key Pain Points Addressed

1. Corrosion Issues with Traditional Chloride-Based De-icers: Conventional de-icing agents like sodium chloride severely corrode roads, bridges, vehicles, and metal structures, while contaminating soil and water sources. Eco-friendly de-icing agents, however, incorporate corrosion inhibitors and plant protection agents, minimizing corrosion toward metals and cement concrete and effectively resolving this longstanding industry challenge.
2. Inconvenience and High Costs of Solid De-icing Agents: Traditional solid de-icing agents require constructing mixing stations for dissolution, resulting in high costs and frequent pipeline blockages due to concentration fluctuations. Liquid de-icing agents, on the other hand, can be directly added to water trucks for immediate use, eliminating the need for mixing station construction and the lengthy dissolution process, thus avoiding pipeline blockage risks and significantly reducing overall costs.
3. Repeated Icing After Snow Melting: Ordinary de-icing agents often lead to re-freezing of melted snowwater in low-temperature conditions, compromising de-icing effectiveness and road safety. High-performance de-icing agents containing sustained-release components effectively suppress refreezing, ensuring long-lasting de-icing effects.
4. Concerns About Environmental Damage: Long-term use of traditional de-icing agents can cause soil compaction, salinization, and vegetation death. Eco-friendly de-icing agents, free of toxic substances and producing byproducts that promote plant growth, meet green transportation development requirements and alleviate concerns about ecological harm.
