hey are blend stocks used to formulate a variety of lubricating oils for use in engines and other machinery. Base oils are used to manufacture products including lubricating greases motor oil and metal processing fluid. Group I BASES: The main field of application of these bases is the formulation of lubricant base oils for the automotive industry, heavy industry, marine applications, and greases. These bases can also be used for the production of white oils and fluxes in the manufacturing of asphalts. GROUP II-III BASES: These oils are especially recommended in very different applications according to their characteristics, from textile and cutting oils for the lightest ones to lubricant formulations for turbines, engines, heat pumps and exchangers, and hydraulic fluids for the heaviest ones.
We are all familiar with bitumen and have used it in our daily lives. Bitumen is mainly used as an adhesive in asphalt, which plays a very important role in road construction and sealing at landfills and hydraulic engineering. This important material has many roles in the world, for example, its other application is the production of roofing membranes and waterproofing for flat roofs and waterproofing of buildings. Bitumen is also used in many areas outside the construction industry because it has the effect of thermal insulation and sound absorption, which reduces foot noise. Bitumen is mostly used in insulation of roofs and roofs, which can prevent moisture and water penetration. Also, bitumen insulation is one of the most common waterproofing techniques in buildings due to its chemical and physical properties and preventing water penetration. Components are used in contact with the floor, floorboards and walls as a horizontal and vertical waterproofing In general, bitumen is used in construction in all parts of the world as the main sealing material for service bitumen, garden bitumen, balcony sealing, and pre-roofing bitumen substructure. Tile bedding such as bathrooms and toilets that are constantly exposed to moisture must be sealed with water to prevent water from penetrating them. There are also different types of bitumen in construction, such as mixed bitumen, emulsion bitumen, Trinidad bitumen, modified bitumen, tar bitumen, loose and mixed construction bitumen, hard construction bitumen, each of which has its own application
