Bitumen Introduction:
Bitumen is a black-colored and dough-shaped material used in moisture insulation and asphalt making. Bitumen has a variety of types, each of which has a special application. Bitumen is a derivative of oil
Penetration degree: Penetration grade test is used to determine bitumen hardness. In this test, a standard needle is penetrated from a 100-gram load in 5 seconds into the bitumen at a temperature of 25 degrees. The amount of penetration is called the tenth mm of penetration. The lower the penetration, the harder the bitumen.
The important application of bitumen is due to the presence of two important properties of this material, impermeability to water and high adhesion due to these features، The main consumption of bitumen is in the way of construction and insulation.
Bitumen types:
Bitumen 40-50:
Bitumen with a penetration degree of 40-50 is a type of bitumen produced in the oxidation process and baton. A baton is a byproduct of crude oil refining that is taken from the distillation tower in the vacuum of oil refineries. In the oxidation process, the baton is exposed to air and reacts with oxygen. This reaction causes bitumen to develop certain properties such as adhesion, durability and resistance to water and moisture.
The penetration degree of bitumen is represented by a double digit number. The first number shows the maximum penetration of bitumen at 25 degrees Celsius in millimeters. The second number shows the minimum penetration of bitumen at 25 degrees Celsius in millimeters. Therefore, bitumen with a penetration degree of 40-50 is bitumen, whose penetration is between 40 and 50 mm at 25 degrees Celsius.
Bitumen with a penetration degree of 40-50 is used in a variety of industries. The most important uses of this bitumen are:
*Road Correction: 50-40 bitumen used for asphalt production. Asphalt is made from a mixture of sand, sand and bitumen. Bitumen 40-50 is suitable for making asphalt due to its high adhesion and durability.
