Bitumen Emulsion Anionic SS1
Bitumen SS1 emulsion is a slow-setting, anionic type, known for its stability during storage even when produced with equipment generating varying shearing forces. This stability is achieved through emulsion-conditioner compositions that include partially desulfonated lignosulfonate, anionic or nonionic emulsifying agents, and optionally, thickeners.
The usage of Bitumen SS1 anionic emulsion involves two phases—water and bitumen—that do not naturally mix. Specifically, the inner phase exists within the outer phase, with particle sizes ranging from 0.1 to 5 microns. Without an emulsifier, the mixture is unstable and quickly separates. However, by adding an emulsifier, such as an alkaline salt with ammonium salt, and mixing at high speed under ISO conditions, a stable Bitumen SS1 emulsion is formed.
Emulsifier content ranges from 3-5%, with total water content between 30-50%. Moreover, the emulsifier imparts anionic charges to Bitumen SS1 particles, turning them into tiny spheres (0.001 to 0.01 mm) that float in water. Importantly, Bitumen SS1 is environmentally friendly, as it contains no flammable materials or kerosene, eliminating the risk of fire during use. Additionally, this anionic Bitumen SS1 adheres strongly to lime-containing building materials.
Bitumen Cationic Emulsion CSS1
Cationic bitumen emulsions CSS1 carry a positive charge, enabling a rapid reaction with aggregates or pavements. The Zeta potential, indicating charge magnitude, affects emulsion stability—the larger the charge, the greater the repulsion. Consequently, a higher Zeta potential accelerates reactions with negatively charged aggregates.
Furthermore, stabilizing cationic emulsions enhances their breaking rate. Although evaporation also contributes to breaking, stabilization slows this process, requiring a balance. After the electrostatic reaction, flocculation and coalescence complete the breaking process. Full asphalt strength is achieved once all water evaporates.
Applications of Bitumen SS1
Bitumen SS1 is used in cold asphalt for cold or humid conditions and sealing applications. In fact, asphalt emulsions like Grade SS1 are common in highway construction, surfacing, and maintenance. They are also suitable for water-repellent surfaces. Moreover, slow-setting emulsions like Grade SS1 are stable enough to mix with fine or dusty aggregates before setting. When anionic, Grade SS1 chemically reacts with Portland cement constituents, forming water-insoluble salts that enhance water resistance.
Packing of Bitumen SS1
Bitumen SS1 is packed in 208 kg steel drums. Typically, a 20-ft container can hold 80 drums. The minimum order quantity (MOQ) is one 20-ft FCL for Grade SS1 shipments.
