Application of Special Acetate Series Products for Deicing and Snowmelt on Municipal Roads with High Environmental Protection Requirements

Cities with strict environmental governance standards raise high requirements for winter road maintenance. De-icing operations must fully guarantee traffic safety, protect municipal public infrastructure, and preserve soil and urban ecological environments. Traditional chloride-based de-icing salts are gradually banned in core urban areas, as they easily corrode road surfaces and buried pipelines, degrade soil quality, and wither roadside landscape vegetation. The following four chlorine-free de-icing products are developed to meet integrated municipal needs for safety, infrastructure protection and ecological environmental compliance.

1. Industrial-Grade Solid Potassium Acetate (Purity ≥99%)

Core Function

This solid product delivers stable long-term anti-icing and snow removal for municipal main roads, slopes and ramp sections. It rapidly clears accumulated ice and snow on road surfaces and lowers the freezing point to effectively prevent secondary icing, ensuring reliable road skid resistance throughout winter. With ultra-low corrosive properties, it protects municipal buried pipelines, metal manhole covers and roadside green vegetation from chemical damage.

Product Advantages

The fully chlorine-free and low-corrosion formula features a metal and concrete corrosion rate only one-tenth of traditional chloride de-icers. It maintains stable de-icing activity under extreme cold conditions, with a freezing point as low as -50°C. Completely biodegradable, it causes no persistent pollution to soil and green plants. The material boasts excellent fluidity and anti-caking performance, fully adapting to large-scale mechanical spreading for municipal road maintenance.

Application Method

Apply 30–50 g/m² for pre-emptive anti-icing treatment before snowfall. For roads covered with frozen ice and compacted snow, the dosage is adjusted to 50–100 g/m². Focus on high-risk road sections including slopes, curved roads and intersections to eliminate potential traffic hazards.

Precautions

The product is highly hygroscopic and requires sealed and dry storage. Excessive application will increase subsequent rainwater and road runoff treatment costs, so dosage must be strictly controlled during operation.

2. Industrial-Grade Liquid Potassium Acetate (50%–60%)

Core Function

Serving as the mainstream emergency de-icing and preventive anti-icing material for municipal roads, liquid potassium acetate quickly melts surface ice and snow. It forms a uniform protective film on road surfaces to reduce snow adhesion. Suitable for rapid deployment before morning and evening rush hours, it ensures safe passage for motor vehicles, sidewalks and non-motorized lanes without damaging urban infrastructure.

Product Advantages

The original solution can be sprayed directly on-site to greatly improve construction efficiency. It remains free of crystallization at -30°C and does not affect road surface friction performance. With zero chlorine content and low corrosivity, it poses no damage to municipal facilities. Fully biodegradable, it causes no harm to surrounding water bodies and landscape vegetation, meeting both domestic and international environmental supervision standards.

Application Method

For preventive anti-icing, spray 20–40 g/m² 1 to 2 hours before snowfall. For emergency de-icing on frozen roads, apply 40–80 g/m². The product can be used with municipal watering trucks for full-coverage road operation.

Precautions

Tank and pipeline insulation is required in extreme low temperatures to avoid increased liquid viscosity and reduced spraying uniformity. Sealed storage after opening is necessary to prevent moisture absorption and solution dilution.

3. Industrial-Grade Liquid Potassium Formate (Concentration ≥75%)

Core Function

Customized for ultra-low temperature winter maintenance in high-latitude northern cities, liquid potassium formate maintains efficient de-icing capacity in severe cold weather. It balances rapid snow and ice removal, municipal infrastructure corrosion protection and urban ecological protection, serving as a reliable special material for cold-region municipal road upkeep.

Product Advantages

Its freezing point reaches -60°C, delivering far better de-icing performance than conventional products at -40°C. It provides extended anti-reicing effects, effectively reducing repeated construction frequency. The material is biodegradable and contains active potassium elements, which benefit plant growth without causing soil or water pollution.

Application Method

The original solution can be sprayed directly in extreme cold environments. The preventive dosage is 30–50 g/m², and 60–100 g/m² is applicable for thick ice removal. Combined use with liquid potassium acetate can optimize de-icing performance and control overall maintenance costs.

Precautions

Due to higher comprehensive costs, it is mainly recommended for core urban road sections. Store in sealed conditions to prevent moisture absorption and attenuation of active ingredients.

4. Universal Eco-Friendly Chlorine-Free De-Icer (Freezing Point: -15°C ~ -60°C)

Core Function

This universal de-icing material adapts to all urban road scenarios, widely applicable for daily maintenance of urban main roads, community roads, park paths and school peripheral roads. It integrates efficient ice melting, ecological safety and economic performance to meet diversified municipal maintenance needs.

Product Advantages

The zero-chlorine formula causes no corrosion or structural damage to roads, pipelines and auxiliary facilities, and produces no adverse impact on green plants and water environments. It features fast ice-melting speed and long-lasting anti-reicing effects. With odorless and non-irritating properties, it is safe for pedestrians and pets, fully complying with global mainstream environmental protection standards.

Application Method

The conventional snow and ice removal dosage ranges from 40–100 g/m², adaptable to mechanical spreading and diluted spraying. It can be compounded with potassium acetate or potassium formate to strengthen low-temperature resistance. Mixing with chloride de-icing salts is strictly prohibited.

Precautions

Different product models correspond to different freezing point parameters; select the appropriate model according to local extreme winter temperatures. Moisture-proof sealed storage is required to avoid caking and performance failure.

Industry Application Case

A core urban area with winter minimum temperatures dropping to -22°C has issued strict bans on traditional chloride de-icing agents to protect urban ecology and infrastructure. The local government adopted a scientific winter maintenance solution, using 60% liquid potassium acetate as the main de-icing material, supplemented by universal eco-friendly chlorine-free de-icers.

This solution ensures complete road de-icing before morning peak hours, keeping road friction coefficients stably within safety standards. Since the implementation of the new scheme, the urban winter traffic accident rate has dropped by 82%, and roadside landscape vegetation achieves a 100% survival rate. Road runoff fully meets urban surface water discharge standards. Compared with traditional environmentally friendly de-icing products, the annual road maintenance cost is reduced by 21%, realizing safe, green and economical winter road operation.
