High-quality hydraulic oil is crucial for both machinery and automobiles. The evolution of hydraulic oil has progressed from anti-rust formulations to anti-oxidant varieties, eventually leading to the well-developed anti-wear options we have today.Hydraulic OilIt is categorized into several types, including high-zinc alkaline, low-zinc alkaline, neutral high-zinc, and ashless. In modern transportation and industry, hydraulic oil is an indispensable component. In hydraulic transmission, to meet the transmission requirements, hydraulic oil should possess the following properties:
　　
The oil demonstrates excellent viscosity-temperature characteristics: within the operational temperature range, the change in oil viscosity due to temperature should be relatively small, thus yielding a higher viscosity index.
　　
2. Its lubricity stands out: Hydraulic oil typically serves as the energy transmission medium, acting as a lubricant for mechanical operation. Its lubricity is exceptional to ensure that the mechanical work is not damaged.
　　
3. Pure in quality, free from mechanical impurities, and non-corrosive.
　　
4. It is less prone to oxidation: Try to avoid or prevent oxidation during or in high-temperature conditions, as it accelerates the deterioration of the oil product.
　　
5. In high-temperature work environments, the high flash point is a concern; in low-temperature environments, its flowability must be excellent.
　　
6. The water point should be better, with a high aeration property to prevent emulsification and foaming.
　　
It boasts excellent compatibility with sealants, coatings, and other solvents.
