What is bitumen SS1
Bitumen SS1 is emulsified asphalt slow-setting, anionic type and are further characterized by their ability to remain stable on storage although produced with equipment that generates a wide range of shearing forces. Such characteristics are imparted to the asphalt emulsions through the use of emulsion-conditioner compositions comprising a partially desulfonated lignosulfonate, preferably an anionic or nonionic emulsifying agent and, optionally, a thickene.
Usage of SS1
Usage of anionic emulsion bitumen SS1 is two phases of water and bitumen which is not possible to mix and first inter phase is inside of outer phase.Particle size of 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 alkaline salt with Ammonium Salt in high speed mixer at ISO condition making bitumen SS1.
Differences of bitumen SS1 and SS1H
The H end of Bitumen SS1H means high viscosity and only 5% bitumen content is higher than normal SS1.
Differences of SS1 and CSS1?
SS1 and CSS1 has differences on emulsifier agent and C show cationic ion and SS1 means Anionic ion and when you use for the surfaces it should be choose right one to have good boundary molecular between bitumen and materials.
Percentage of emulsifier is 3-5% and total water content is between 30-50%.By adding Emulsifier to bitumen and water we put anionic electron on the material and each particle of bitumen became like as circle with size of 0.001 to 0.01 mm and become floating in water. Using bitumen SS1 is environmental friendly since any flammable material or kerosene is not used and firing of the bitumen during the usage would be zero.
This kind of anionic bitumen has more adhesive to building material which is contain lime.
Bitumen cationic emulsion CSS1
Cationic bitumen emulsions CSS1 have a positive charge and hence a direct and very rapid reaction between the emulsion and an aggregate or pavement is possible. The size of the charge, or the Zeta potential affects stability,the larger the charge the greater the repulsion, but as the aggregate is negatively charged the higher the zeta potential the more rapid the reaction.
So it is possible to stabilize a cationic emulsion in the same way that makes it a more rapid break.
The other mechanism of evaporation is available too but as the emulsion is stabilized this form of break becomes slower. Thus a balance must be struck.After the electrostatic part of the reaction is complete the emulsion will rely on flocculation and coalescence to complete break.
After break is completed the water must still be completely evaporated for the residual Asphalt to achieve full strength.
Application of bitumen SS1
It is using for cold asphalt in cold or humid or sealing.Asphalt emulsions are widely used in highway construction, surfacing and maintenance. They are also used in various other applications where water repellent surfaces are needed. Slow-setting emulsions are grades of emulsions that are sufficiently stable to allow mixing with fine or dusty aggregate mineral particles and further processing before setting to a coherent mass. Such grades of asphalt emulsions (bitumen SS-1 grade), when anionic, react chemically with portland cement constituents forming a water-insoluble salt and thus possess valuable water-resistant characteristics.
