Product Details:

1. Introduction

Cationic middle setting bitumen emulsifier is a type of emulsifier designed for the production of bitumen emulsions. Unlike traditional emulsifiers, this product does not require the addition of acid or pH adjustment during the emulsion process. This greatly simplifies the production process, reduces equipment maintenance, and saves on labor and materials, leading to a reduction in the overall cost of emulsified bitumen. By eliminating the need for acid, this emulsifier prevents corrosion of equipment, so there is no need to consider anti-corrosion measures when selecting equipment, significantly reducing capital investment in machinery.

2. Function and Features

• Simplified Production: No acid required during emulsification, reducing production steps and cutting costs.
• Cost-effective: Reduces equipment maintenance, labor costs, and the need for anti-corrosion measures in machinery.
• Enhanced Equipment Longevity: Prevents corrosion to emulsification equipment, which extends the lifespan of production machinery.
• Environmental & Safety Benefits: Non-toxic with a pleasant aroma, making it a safer choice for manufacturing environments.
• Versatile Application: Suitable for a wide range of road construction applications, including surface treatments, fog seals, tack coats, and more.

3. Technical Specifications

• Active Ingredient Content: 40 ± 1%
• pH Value: 2-3 or 6-8
• Appearance: White or pale yellow liquid
• Odor: Non-toxic, aromatic odor
• Solubility: Soluble in warm water and some organic solvents
• Dosage: 8-12‰ of the total amount of emulsified bitumen, with variations 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: 130-140°C
• Emulsifier Dosage: 10-12‰ (for 70# bitumen)
• Bitumen to Water Ratio: 5:5

4. Instructions for Use

• Aqueous Solution Temperature: The temperature of the emulsifier’s aqueous solution should not exceed 70°C during production.
• Cold Weather Handling: In winter or low-temperature conditions, the product may stratify, with the lower portion turning into a paste. However, heating or the return of ambient temperature will restore it to its original state.
• Adjustment for Different Bitumen Types: The amount of emulsifier used should be adjusted based on the type of bitumen. The optimal amount should be determined through experimentation.

5. Application Scenarios

• Surface Treatments: Ideal for surface treatments, including slurry seals and fog seals, to improve the durability and performance of the pavement.
• Tack Coats: Used for tack coats to improve the bonding between layers of bitumen and aggregates in road construction.
• Paving and Sealing: Suitable for applications such as penetration-type pavements and undersealing layers.
• Road Construction: Widely used in various road construction processes, especially for projects requiring middle-setting bitumen emulsions with excellent performance in adhesion and stability.

6. Performance and Advantages

• Improved Adhesion: Ensures a strong bond between bitumen and aggregate surfaces, enhancing pavement durability and reducing maintenance costs.
• Enhanced Durability: Offers superior performance against weathering, aging, and water damage, extending the lifespan of the treated surfaces.
• Cost and Time Efficiency: By simplifying the emulsification process and reducing production costs, it leads to significant cost savings in large-scale road construction and maintenance projects.
• Environmental Protection: Safe for the environment, with no toxic components or harmful fumes during production and application.

Summary

Cationic middle setting bitumen emulsifier is an advanced emulsifier that simplifies the production of bitumen emulsions, cutting costs and reducing the need for acid or pH adjustments during emulsification. Its non-toxic, environmentally safe properties make it a suitable choice for road construction, offering significant benefits in performance, cost savings, and equipment longevity. Ideal for surface treatments, tack coats, and a variety of other road construction applications, this emulsifier improves adhesion, durability, and stability, ensuring long-lasting and high-performance results.
