First, the principle of asphalt.
Bitumen is a hot thickening substance of polymer by heating petroleum or other permeating oil raw materials, evaporating them and removing the grease and impurities in them. The essence of asphalt is a macromolecular organic compound, which has excellent adhesion, plasticity and waterproofness, and is an indispensable one among a variety of building materials.
Second, the manufacturing method of asphalt.
1.Raw material collection and processing.
Bitumen is mainly made by processing permeating oil feedstocks such as petroleum, so these raw materials need to be collected first. After collection, it needs to be treated, including desulfurization, denitrification, potassium removal, deoxygenation, etc. These processes can make the raw material more pure, which is conducive to the manufacture of high-quality bitumen.
2.The production process of asphalt.
1) Heating: The processed raw materials are heated to a certain temperature by heating to make them become viscous liquids.
2) Polymerization: The heated raw materials are deeply processed to turn them into polymers, thus forming asphalt.
3) Adjustment: By adjusting the composition and properties of asphalt, it can adapt to different use needs.
4) Packaging: The finished asphalt will be packaged and sold directly or used in construction projects.
Third, the application field of asphalt.
Asphalt is widely used in construction fields such as highways, airport runways, roof waterproofing, water conservancy projects, bridges and tunnels. In these areas, asphalt can exert its excellent properties, such as high adhesion, plasticity, waterproofing, etc., to ensure the quality and stability of buildings.
In summary, asphalt is a viscous polymer made by processing petroleum and other raw materials, which has excellent adhesion, plasticity and waterproofness. In the field of construction, asphalt is widely used in construction fields such as highways, airport runways, roof waterproofing, water conservancy projects, bridges and tunnels.
