Production Introduction：
SDT2008H additive package to ashless AW hydraulic oil is the latest type compound additive developed by Research Institute of Petroleum Processing for replacement of imported products of the same kind. It can be used to prepare high pressure ashless AW hydraulic oil of high grade with its addition amount of 0.8% (antifoam agent be added additionally). It can be added into paraffin grade high viscosity neutral oil (HVIS and HVIW) to prepare products of N32, N46, N68 and N100 viscosity grades. Through the lab physical and chemical properties and high pressure pump rig test, its quality conforms to the national standard GB11118.1-94 L -HM: Quality Standard for Mineral Oil Type Excellent Hydraulic Fluid and reaches the requirements as specified in DENISON HF-0 specification of the United States, it is also in line with the requirements as specified in ISO11158-97, vickers m-2950s DIN 51524(ll) as well as cincinnati milacron P-68P-69 P 70, attaining the advanced level of current international products of the same kind.
Properties and purpose: as the product does not contain Zinc and other metals and has excellent high pressure EP/AW property and thermal oxidization stability, the AW hydraulic oil prepared with it mainly finds its use in the hydraulic system with over 30.0 Mpa at the plunger pump and 14.0 to 17.5Mpa pressure at the vane pump; it is an ideal motor transmission medium, extensively applied in metallurgy, plastic, mine and heavy duty engineering mechanical equipment such as in the hydraulic system of the truck loader, the excavator, the tilting car, the forming machine and the pressing machine. It can also extend its service life by reducing the mechanical wear of the hydraulic machinery and improve its economic benefits by lowering oil consumption and cost.
