Product Details:

1. Introduction

Cationic middle setting bitumen emulsifier is a quaternary ammonium salt-based bitumen emulsifier with strong emulsification capabilities. This emulsifier provides exceptional emulsification and storage stability, enabling the emulsification of various grades of modified bitumen, including heavy-duty bitumen and imported bitumen. Additionally, it causes no significant damage to bitumen during the emulsification process. This makes it an ideal choice for high-performance bitumen emulsions used in road construction and maintenance projects.

2. Function and Features

• Powerful Emulsification: Offers exceptional emulsification capability, making it suitable for emulsifying a wide range of bitumen grades, including heavy-duty and imported types.
• Stable Storage: Provides excellent storage stability, preventing separation or degradation of the emulsion during storage.
• Non-Damaging to Bitumen: Does not cause significant damage to bitumen, ensuring the quality and performance of the final product.
• Safe and Non-Toxic: The emulsifier has a pleasant aroma and is non-toxic, making it safe to handle in production environments.
• Cost-Efficient: Reduces the need for additional processing or additives, lowering the overall cost of producing bitumen emulsions.

3. Technical Specifications

• Active Ingredient Content: 50 ± 2%
• pH Value: 6-8
• Appearance: Milky white or pale yellow paste
• Odor: Non-toxic, aromatic smell
• Solubility: Soluble in hot water and some organic solvents
• Dosage: 8-10% of the total emulsified bitumen, with the specific dosage depending on the type of bitumen used. The optimal dosage should be determined through experimentation.
• Water Temperature: 55-70°C (for emulsifier aqueous solution)
• Bitumen Temperature: 125-130°C
• Emulsifier Dosage: 8-10% (for 90# bitumen)
• Bitumen to Water Ratio: 5:5

4. Usage Instructions

• Emulsifier Solution Temperature: The temperature of the emulsifier's aqueous solution should be kept between 55-70°C during production.
• Production Process: The product is in paste form. To use, first add an appropriate amount of water to the mixing tank. Then, add the measured emulsifier to the water, heat to the required production temperature, and start stirring. After about 5 minutes, the emulsifier will completely dissolve. The solution is ready when no emulsifier particles are visible in the water.
• Cold Weather Handling: In colder temperatures, the emulsifier may become more viscous or slightly solidify. However, it will return to its original consistency once heated.

5. Application Scenarios

• Road Surface Treatments: Suitable for road surface treatments such as slurry seals, tack coats, and micro-surfacing, improving road durability and performance.
• Bitumen Emulsions: Used for creating high-performance bitumen emulsions for use in road construction and maintenance projects.
• Waterproof Coatings: Can be incorporated into waterproof coatings and other bitumen-based products to enhance adhesion and durability.
• Industrial Applications: Ideal for use in various industrial applications that require stable bitumen emulsions, including waterproofing membranes and coatings.

6. Performance and Advantages

• Improved Bitumen Quality: Enhances the emulsification of bitumen, improving its performance in road construction and waterproofing applications.
• Cost Savings: By eliminating the need for acid or other additives, the product reduces overall production costs.
• Long-Term Storage: Excellent storage stability means the emulsifier remains effective over time, reducing waste and the need for frequent replacements.
• Environmentally Friendly: Non-toxic and safe for both the environment and production workers, meeting modern safety and environmental standards.

Summary

Cationic middle setting bitumen emulsifier is a high-performance emulsifier that simplifies the production of bitumen emulsions, enhances the quality of bitumen, and reduces overall production costs. With strong emulsification power, stability, and non-damaging effects on bitumen, it is ideal for road surface treatments, bitumen emulsions, and waterproof coatings. Its safe, non-toxic composition and excellent storage stability make it an essential product for road construction, maintenance, and industrial applications.
