Physical and chemical properties insulation bitumen emulsion
Insulation including bitumen emulsion base in which Qyrhayy the degree of penetration and softening temperature by various emulsifiers such as bentonite at a temperature of 80 to 90 ° C in water emulsions are converted. After drying the insulation resistant to water penetration and better physical and mechanical properties of bitumen show.
Production of emulsion that can withstand the cold temperature stress and thermal insulation have long been of interest to researchers and manufacturers in this industry. The first bitumen emulsion was recorded in 1922 by Hsuan Maki.
The insulation in all anti-corrosion system, for example in coatings and construction industries pipes can also be used. This insulation against water penetration resistance after drying and physical and mechanical properties which are completely under the influence of physical and mechanical properties are bitumen.
Despite the above advantages resulting emulsion has physical and chemical properties suitable insulation to withstand high temperature range. So can be used to strengthen insulation and fix the defects of emulsion polymers can be used. The use and application of polymers in nearly every industry has a very special place. The unique properties of polymers has caused tension to increase performance and resilience of crops to be used it in vast quantities. For example, polymers such as SBS flexibility to increase the efficiency and dynamic properties of the bitumen. Bitumen emulsion base materials are also exempt from this rule so that they can be used in the bitumen modified by a polymer, and the ability to increase insulation.
