Bitumen #30 Description:
Bitumen #30 is a soft grade of blown bitumen with a softening point typically in the range of 30+5°C, making it relatively soft compared to other bitumen grades. It is primarily used for various construction and industrial applications. Please note that the information provided here is a translation of the text you provided.
Description: Bitumen #30 is a softer grade of blown bitumen with a softening point around 30°C (+5°C tolerance). This grade of bitumen is produced by subjecting bitumen #60 to a heating process where it loses approximately 5% of its total weight, resulting in the creation of Bitumen 30.
Packaging: Bitumen #30 is available in bags and drums. However, it’s important to note that during the summer months, packaging it in bags can be risky due to the potential for bitumen leakage inside the container.
Applications: Bitumen #30 finds utility in various applications, including:
- Underground Moisture Waterproofing: Used to protect underground structures from moisture infiltration.
- Nuclear Power Engineering: Employed in nuclear power engineering projects for pipeline engineering, bottom anticorrosion, and asphalt production.
- Waterproofing Membrane and Moisture-Proof Paper Production: Utilized in the manufacturing of waterproofing membranes and moisture-resistant paper products.
- Anti-corrosion Paint and Waterproof Production: An ingredient in the production of anti-corrosion paints and waterproofing materials.
- Road and Bridge Caulking: Used for sealing and caulking purposes in road and bridge construction projects.
