Description
Anionic bitumen emulsion SS-1h is a slow-setting anionic asphalt emulsion (i.e., low reactivity) low viscosity and a hard asphalt residue that is designed for various paving and industrial uses.
Asphalt emulsions are classified according to the electric charge that surrounds the emulsion’s asphalt particles (i.e. whether it is a cationic or an anionic emulsion) and how quickly the suspended asphalt particles separate from the surrounding water (“breaking”).
For anionic and emulsions, there are several grades of different braking characteristics. Rapid-setting emulsions are used for surface dressing, while medium or slow-setting emulsions are used for ‘mixtures’, that are mixed with aggregate either in concrete-type mixers or in situ. Therefore, stone mixtures require medium-setting Emulsions and sand mixtures require a slow-breaking emulsion.
With anionic emulsions, the breaking process is predominantly by evaporation of the water in the emulsion continuous phase. Because of this, anionic emulsions are susceptible to temperature and humidity in terms of their breaking properties. Usage of anionic bitumen emulsion SS-1h is two phases of water and bitumen which are not possible to mix and the first interphase is inside of outer phase.
The particle size of the emulsion is 0.1 to 5 micron. In normal conditions and without emulsifier the two parts of emulsion SS1 is unstable and quickly will segregate. By adding emulsifier into water and bitumen that is the alkaline salt with Ammonium Salt in the high-speed mixer at ISO condition making Bitumen SS-1h.
Application of Anionic bitumen emulsion SS-1h
The main applications of Anionic bitumen emulsion are waterproofing, building application, highway construction, surfacing, and maintenance. Anionic emulsion is obtained by an electric field. In an anionic emulsion, the droplets migrate from the anode. Anionic bitumen emulsion SS-1h is a slow setting, anionic type of bitumen. special emulsifiers, water, and other additive have been gone through anionic Slow Setting bitumen Emulsion is the cold/non-fibered liquid applied waterproofing bitumen emulsion.
Anionic SS-1h must be spray applied by using a suitably calibrated distributor & experienced personnel.Emulsion SS-1h can be applied under the same conditions of the subsequent pavement placement; however, break time and bond strength can be affected by extreme weather conditions. SS-1h should never be used when pavement or ambient temperatures are near or below freezing. Performance and bond strength can be severely compromised under these conditions. If dilution of SS-1h is required it is important that the water be added to the emulsion and at a water temperature equal to or greater than the temperature of the concentrate emulsion but not greater than 200 F.
Packing of Anionic bitumen emulsion SS-1h
Packing of this product is in the new thick steel drum on the pallet to prevent any leak inside of container also bulk in bitutainer and tanker.
