I. Production Process

The production process for block asphalt primarily includes the following steps:

1. Raw Material Selection: Opt for high-quality raw materials such as petroleum asphalt to ensure quality meets production requirements.

2. Heating Melting: Add the raw material to the heating kettle, heat to the molten state, and maintain a certain temperature range.

3. Molding and Cooling: Liquid asphalt is molded into blocks through molds or extruders, then naturally or forcibly cooled in a cooling tower.

4. Cutting and Packaging: After cooling, the asphalt blocks are cut to standard sizes as required and then packaged.

II. Performance Features

Blocky asphalt features the following performance characteristics:

1. High Softening Point: The softening point is typically above 100°C, with some products reaching over 200°C, suitable for high-temperature environments.

2. High bonding: Excellent bonding properties, effectively bonding aggregates, enhancing the overall performance of the material.

3. Hot Stability: Maintains stability at high temperatures, resists softening or flowing, suitable for refractory materials and high-temperature environments.

4. Corrosion Resistance: Excellent tolerance to chemicals such as acids and alkalis, extending service life.
