Asphalt anti sticking and isolation agent is a chemical formulation used to prevent the adhesion of asphalt materials, widely used in the following scenarios:
1. Asphalt production and transportation
Asphalt tanker trucks and storage tanks: Spray on the inner wall of the tank to prevent asphalt from sticking after cooling, making it easy to unload and clean.
Pipeline and pumping equipment: reduce asphalt residue, keep equipment unobstructed, and lower maintenance costs.
2. Production of asphalt mixture
Mixing plant equipment: used for mixing tanks, discharge ports, and other parts to avoid adhesion of hot asphalt and improve production efficiency.
Transport vehicles (dump trucks, pavers): prevent the mixture from sticking to the carriage or hopper, and ensure that the discharge is clean.
3. Road construction and maintenance
Paving operation: Spray on the ironing board of the paver and the roller of the roller to reduce the adhesion of asphalt mixture and ensure the smoothness of the road surface.
Construction tools (shovel, rake, etc.): convenient for workers to operate and reduce the difficulty of tool cleaning.
Bridge expansion joints: prevent asphalt filling from bonding with metal components and extend their service life.
4. Building materials and industrial applications
Waterproof roll production: used in the forming and cooling process of asphalt based rolls to avoid interlayer adhesion of the rolls.
Roof asphalt construction: Spray on the surface of construction tools or base layer to facilitate uniform laying of asphalt coating.
Anti corrosion of railway sleepers: Treat the sleepers soaked in asphalt to prevent them from sticking to each other.
5. Other special scenarios
Mold demolding: used for asphalt test molds (such as Marshall test molds), rubber product molds, etc., to achieve rapid demolding.
Waste disposal: When cleaning asphalt waste, reduce the adhesion to containers or equipment.
6. Advantages
Efficient anti sticking: reduces the adhesion between asphalt and materials such as metal and plastic.
High temperature resistance: adapted to the high temperature environment of asphalt (usually up to 150 ° C or above).
Environmental safety: Some products are water-based or biodegradable formulas to reduce harm to the environment and human health.
7. Precautions
The appropriate type of isolation agent (such as oil-based, water-based, emulsion type) needs to be selected based on specific scenarios (such as temperature, contact materials).
Before construction, the surface should be cleaned to ensure even spraying and avoid affecting the bonding performance of asphalt (such as bonding with aggregates).
By reasonable use, asphalt anti sticking and isolation agents can significantly improve construction efficiency, equipment lifespan, and engineering quality.
