1. Different classification

According to the composition of the environment, sodium asphalt sulfonate natural asphalt can be divided into asphalt, lake asphalt, bottom asphalt, etc. D. Asphalt usually occurs in rock cracks or in a mixture with the ground. Asphalt is a natural bitumen that continuously falls from the earth's crust and occurs by prolonged transpiration and condensation in rocks and in cracks between rocks. Lake asphalt is a kind of natural accumulation asphalt, which is composed of clay and water in the form of emulsion, mainly in the form of lake surface.

Petroleum asphalt can be roughly divided into straight-run asphalt, solvent-degreased asphalt, oxidized asphalt, mixed asphalt, emulsified asphalt, and modified asphalt according to the production method. d.; From the appearance, it can be roughly divided into liquid asphalt, solid asphalt, diluent, emulsion, modified body, etc. d.; According to the use, it can be divided into travel asphalt, construction asphalt, waterproof and  moisture-proof asphalt, various special asphalts, and named the use or function.

2. Different uses

Natural asphalt is mainly used for modification sodium asphalt sulfonate or blending of high-grade bridge deck asphalt, drilling aid or preparation of special high-softening asphalt. As a green, low-carbon and environmentally friendly new material, natural asphalt will be widely promoted at all levels of highway construction.

Petroleum asphalt is mainly used as materials, materials and fuels for capital construction, such as transportation (road, railway, aviation), construction, agriculture, water conservancy, industry (extractive industry, manufacturing), civil use, etc.

3. In a different sense

Natural bitumen is formed in nature through prolonged kneading of the earth's crust and gradual modification of the contact between air and water. Natural asphalt exists in a natural way, often mixed with a certain proportion of minerals. According to the composition of the environment, it can be divided into asphalt, lake asphalt, submarine asphalt, etc.

Petroleum bitumen is a product of crude oil processing. It is a mucus, semi-solid substance or solid at constant temperature. It mainly contains alkyl and nepalyl derivatives, and is soluble in trichloroethylene. If you have any other questions, please sodium asphalt sulfonate contact us for details or contact us directly.
