Analysis of Core Technical Indicators
Vacuum diffusion pump oil IOTA 705 appears as a colorless and transparent oily liquid in physical form. This clear appearance not only facilitates observation but also reflects its pure single-component characteristics. Regarding key technical parameters, the viscosity of this oil at 25℃ is maintained between 170 and 175 mm²/s, and the refractive index is controlled within the range of 1.5765 to 1.5785. Its relative density at 25℃ is between 1.090 and 1.10, the flash point (open cup) reaches or exceeds 243℃, and the freezing point is lower than -14 to -18℃. These rigorous physical and chemical indicators collectively ensure its fluidity and safety under complex working conditions. Vacuum Performance and Thermal Stability
In terms of vacuum performance, IOTA 705 exhibits an extremely low saturated vapor pressure of less than 3x10⁻¹⁰ torr, with an ultimate vacuum of less than 1x(10⁻⁹~10⁻¹⁰) torr. This low vapor pressure characteristic prevents it from volatilizing easily in the high-temperature working environment of diffusion pumps, thereby maintaining stable pumping efficiency. Meanwhile, it possesses good thermal stability and oxidation resistance. It is not prone to cracking or carbon deposition under prolonged high-temperature heating, effectively preventing the generation of corrosive by-products and ensuring the long-term stable operation of the equipment. Extensive Industrial Application Scenarios
Relying on the above stable performance, IOTA 705 is widely used in multiple important industrial fields. In the high-vacuum smelting industry, it provides a pure environment for metal smelting and purification. In the electron tube industry and light bulb manufacturing, it helps maintain a high-vacuum state inside the products, extending their service life. In addition, in high-vacuum coating processes, atomic energy accelerators, and the operation of precision equipment such as electron microscopes, IOTA 705 also plays an indispensable role, serving as a reliable fluid medium in modern industry and scientific research.
