Technical Data Sheet Bitumen 60/70 Paving Grade Bitumen Description Bitumen 60/70 has the highest-boiling point, heaviest and most polar fraction from the vacuum distillation of crude oil. Bitumen 60 70 is composed of asphaltene and maltene. The heavy insoluble asphaltene molecules give bitumen 60/70 its body and softening point while the maltenes are oily and make asphalt flexible. Asphalting molecules are soluble in aromatic solvents like toluene but insoluble in heptane. The maltenes are heptane-soluble molecules and less aromatic. Applications Bitumen 60/70 is a high-quality penetration grade bitumen used in road construction and other similar applications. Bitumen penetration grade 60/70 is semi hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Bitumen 60/70 is most used bitumen grade and basic material for all other bituminous products.

Purification in drinking water, domestic sewage, industrial supply water, industrial sewage, industrial circulating water, urban supply water and urban sewage. It is mainly used in sewage disposal in industries such as printing and dyeing industry, steel mills, sewage treatment plant, paper mill, etc. PAC ADVANTAGES: 1. Ease of application 2. Coagulates very effectively in low as well as high turbidity water. 3. Rapid & better floc formation as compared to Alum. 4. Less reduction of pH compared to Alum. 5. Very less sludge generation. 6. No requirement of other flocculation aids. 7. Reduced Sedimentation Time. 8. Effective in wide pH range. 9. Lower resudual aluminium and other heavy metals as compared to Alum. General Introduction: 1, Aluminium chlorohydrate is a group of salts having the general formula AlnCl(3n-m)(OH)m. It is used in deodorants and antiperspirants and as a flocculant in water purification. 2, Other names for pac are basic polybasic , aluminium hydroxide, and aluminium oxychloride and aluminium chlorohydrate. 3, PAC is composed with a series of different polymerizing power of abio-macromolecule compound, it occupying best configuration distribution, the main content is which has high electricity polymerization link distribution figure provided with Keggin configuration, due to it have high electric neutralization and united function to cooloid and fine substance in the water, it mightly wipe off micro-poison and heavy metal ion, PAC has stable capability and configuration character. 4, synthetic polymers dissolved in water. They react to form insoluble aluminium poly-hydroxides which precipitate in big volumetric flocs. The flocs absorb suspended pollutants in the water which are precipitated with the PAC and can together be easily removed. 5, PAC products are used in water treatment for removal of suspended solid (Turbidity) and other contaminants such as natural organic matter from surface water, Micro - organisms and colloidal particles, silt and clay are stabilized by surface electrostatic charges preventing the particles from coalescing. It is advantageous in water of low to moderate turbidity, possibly because of the greater charge neutralizing capacity relative to alum. 6, Poly(PAC)is a kind of highly effective water purificiant, which is wildly used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water.
