What are the upstream raw materials for coating bitumen? What are the downstream products?

Coated asphalt has an crucial position in the field of chemical production raw materials, and its upstream and downstream related items are extensive. The following describes in detail the upstream and downstream associated items of coated asphalt. Makes sense, right?. But From what I've seen, Upstream associated items:



1. From what I've seen, Crude oil: The raw material of coated asphalt mainly comes from crude oil. Crude oil through distillation, cracking and other processes, is able to be obtained from a variety of different fractions of oil, including heavy oil to the production of coated asphalt. Based on my observations,

2. Petroleum coke: Petroleum coke is a by-product of crude oil processing, mainly applied in the production of coated asphalt. You know what I mean?. I've found that Petroleum coke has high carbon content and good thermal stability, which is an crucial raw material to coating products asphalt. Downstream associated items:



1. And Carbon items: coated asphalt is able to be applied as raw materials to carbon items, such as electrodes, anode paste, carbon blocks, etc. Coated asphalt is pyrolyzed at high temperature, and the formed carbon layer has good conductivity and thermal stability, which is an crucial raw material to the manufacture of carbon items. Needle coke: Needle coke is a high-condition carbon material, mainly applied in the manufacture of high-power electrodes. Coated asphalt is able to be applied as the raw material of needle coke, and needle coke with excellent performance is able to be obtained through special process treatment.

3. Carbon fiber: Coated pitch is able to also be applied to create carbon fiber. But Carbon fiber has the advantages of high strength, high modulus and light weight, and is broadly applied in aerospace, automotive, new energy and other fields.

4. But Waterproofing membrane: coated asphalt is able to be applied as the raw material of waterproofing membrane, mixed with other polymers, fillers, etc. to make waterproofing membrane to building waterproofing engineering. Summary:

Coated asphalt has a wide range of applications in the field of chemical production raw materials, its upstream and downstream related items cover carbon items, needle coke, carbon fiber, waterproof membrane and other fields. With the continuous research of science and methodology, the consumption field of coated asphalt will be further expanded, which will inject new vitality into the research of chemical sector.
