Gilsonite bitumen

Gilsonite bitumen

Natural bitumen is known as bitumen, Gilsonite or Unitaite (from the Unitaite mountains in the US). Gilsonite is one of the derivatives of crude oil to change reaching the earth’s surface due to geoglogical changes and finding an appropriate and dry space: to changes This material is an important industrial material which is found in a limited number of countries. Iran is one of the few countries which have a high reserve of natural bitumen. Among the different provinces of Iran, Kermanshah is considered one of the richest province regarding the natural bitumen reserves.

Physical and chemical properties insulation bitumen emulsion

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.

Types of bitumen

Types of bitumen

Other substances from crude oil or refine it. This material has been produced from raw materials over millions of years in the basement arise. Organic matter and sludge in layers hundreds of meters thick stack together. Weight layers, the sludge and sediments and sedimentary rock are compressed together. The effect of global warming and a series of biochemical and microbial processes with the pressure of this material are converted to oil. Chemical composition of crude oil to a large extent related to the source and location of its production. Around 1500 the world's crude oil supply from the North Sea, the Middle East, South America, Asia and even Australia there. Chemical characterization of bitumen is key to the production of bitumen with their respective properties. The climatic conditions of each region needs its own pitch. Bitumen has a complex chemical composition, which can span a combination of physical properties similar and provide the same. Klydyst to characterize the chemical composition of bitumen in the bitumen produced by those refined.

Stretch property bitumen

Stretch property bitumen

Stretch property bitumen (Ductility) to the length of a sample of bitumen (in cm) it is said that the standard form drawn and elongated to reach the point of interruption. Bitumen is appropriate traction properties against temperature changes will expand and contract. Stretch properties depend on the degree of difficulty bitumen and tar that it is low stretch properties will be hard and brittle. If you have a good stretch properties of bitumen and asphalt is rarely consumed in the cold winter season will be on the left.
