More Information
Summary:The vacuum residuum is refined by deasphatization and ketone-benzol dewaxing, the resulted heavy lubricant oil is used as basic oil. It is put into blending kettle, stirred and heated, to which additives T602, T705 are added, and stirred and heated again, the finished oil is thus produced. Said oil possesses pumpability, high cohesion, fine sealing property, compressive resistance being 70 MPa, rust-resistant, sulfur-resistant.
