Today, there are different types of waterproofing in consumer markets that are offered at different prices. The price of domestic export bitumen in the Iranian market is used as one of the very special products. This product can easily be widely traded and has a very special return for buyers in Iran. You can buy First rate bitumen from this site at a reasonable price.
Where is bitumen produced?
Today, bitumen is mainly obtained from oil. There are two general ways to extract bitumen from oil:
• Distillation method
• Aeration method
In the first method, depending on the feed and the method of refining after vacuum distillation, a bitumen with the necessary physical characteristics for use in road construction and industrial applications is obtained.
In the second method, the vacuum residue obtained is usually very low viscosity and very high penetration degree of 400-300 tenths of a millimeter.
This product has low asphalt and can not be used for road construction in tropical and temperate regions. In order to convert this bitumen residue into bitumen with suitable physical properties, heavy molecules such as asphaltene must be added during the process.
To do this, air, which is a mixture of different gases such as oxygen, nitrogen, carbon dioxide, etc., is compressed with the help of a compressor and injected into a tower containing molten bitumen from below at 200 ° C. This process can be continuous or discontinuous.
This process, known as the semi-aerated process, leads to the production of semi-blown bitumen with a suitable degree of penetration and soft point (85/100 or 60/70), which are used in road construction and building waterproofing applications. If the aeration process is continued in the same unit or the next aeration unit, the degree of penetration of bitumen will gradually decrease and its softening point will increase.
The result is blown bitumen with very low penetration degrees and very high softening points of 110.10, 90.15 and 85.25. These types of bitumen have construction applications and are used as additives in moisture insulation. bitumen manufacturers produce this product in different packages.
Price changes of bitumen in 2020
The price of export and domestic bitumen in Iran has been studied as one of the important parameters and this has caused all buyers to have very good samples of this product. Therefore, the parameters that are effective in these prices can be examined and named:
- Exchange rate
- Prices of raw materials
- Oil prices
- Metal prices in the barrel production sector
- Shipping costs
- Insurance costs
- Low costs
- International shipping costs
These cases have made it possible for all companies and buyers throughout Iran to have very good access to this product and to have quality samples of this product throughout Iran. bitumen suppliers export different types of this product.
