Specifications of CutbackBack SC800
If you want to use SC800 bitumen for your company, it is better to have complete information about this bitumen. SC800 bitumen is one of the types of long-lasting bitumen which is produced from the combination of pure bitumen and a heavy industrial solvent.
Factories use 70% pure bitumen and ASTM D 2026M-15 standard in preparing this bitumen. The specifications of Cutback Back SC800 are also determined based on these two items and are according to the following items.
Kinematic Viscosity of SC800 Cutback Back
Viscosity of bitumen means the resistance of bitumen to flow. This index is 800 to 1600 mm2/s at 60 degrees Celsius.
The flash point of Cutback Back SC800
The flash point of SC800 bitumen refers to the temperature at which the vapors of this bitumen ignite near the ignition source. The ignition point of this bitumen is calculated with Cleveland’s open apparatus and 70 degrees Celsius is obtained.
Volume percentage of distillates in SC800
The volume percentage or the concentration of the solution must be measured in the laboratory after distilling the bitumen solution. The volume percentage of SC800 bitumen at 360 degrees Celsius is 15%.
Kinematic viscosity in SC800 distillation residue
The viscosity of SC800 cutback bitumen is calculated on the residue of distilled materials at 60 degrees Celsius. This index is obtained in SC800 bitumen, about 1000 to 16000 square millimeters per second.
Application of Cutback Back SC800
The main application of soluble bitumen is in road construction. This bitumen is used in the production of industrial cold asphalt, base, lining and top for granulating continuous asphalt. Of course, note that the setting time of SC800 soluble bitumen is longer than that of retarding bitumen, and the evaporation of its solvent takes longer.
The application of Cutback Back SC800 is also known as instant stain remover and is used in instant staining of asphalts. This bitumen is used less than other types of soluble bitumen.
The price of SC800 Cutback
The price of soluble bitumen and other petrochemical products are based on the price of oil. On the other hand, the price of oil also depends on the current price of currency and dollar. For this reason, the price of soluble bitumen SC800 may be different on different days of the week.
The price of this bitumen depends on other factors such as the manufacturing company, the amount of pure bitumen and the type of solvent, and sometimes it has different prices in different factories. So, to order all kinds of bitumen, pay attention to the daily price of oil, dollar and currency.
Buying a SC800 bitumen
Before buying SC800 bitumen, you should know important points about this matter. Long-lasting bitumen SC800 is available in different bulk (tanker) forms, new barrels and used barrels of 220 liters. The value of buying a SC800 backhoe depends on the appropriateness of its price and quality.
What are the ingredients of long-lasting soluble bitumen?
Slow Curing Bitumen, known by the abbreviation SC, can be produced from the combination of pure bitumen and heavy industrial solvents. These industrial solvents can be diesel or black oil.
One of the other methods of producing long-lasting bitumen is the distillation of crude oil and obtaining it directly. In this case, the solvent oils have not yet been separated from the oil. The time required for this bitumen is much longer than that of quick-setting and slow-setting bitumen, and its solvents evaporate more slowly.
Types of slow-setting bitumen
Retardant bitumen is available in 4 different types. Types of this bitumen are classified based on their speed and viscosity. The number of each of them corresponds to the viscosity of bitumen in centistokes (Cst). This category is as follows:
SC-70
This long-lasting bitumen has the lowest viscosity among other long-lasting bitumen and has 50% pure bitumen in its composition.
SC-250
SC-250 retarding bitumen has more viscosity than type 70. 60% pure bitumen is used to produce this type of long-lasting bitumen.
SC-800
Another type of long-lasting bitumen is SC-800. This item of long-lasting bitumen has 70% pure bitumen in its composition.
SC-3000
The last type of long-lasting bitumen is SC-3000, which has the highest viscosity among long-lasting bitumen. This bitumen has 80% pure bitumen in its composition.
