Perfluoropolyether Oil: The Highly Efficient Coolant of Choice for Space Capsule Simulations

In scenarios where pumps are vacuum-circulated to simulate space capsule environments, the performance of the coolant directly determines experimental accuracy and equipment stability. Perfluoropolyether lubricant, with its unique molecular structure, is an ideal choice for this trial.

Its core advantage lies primarily in its extreme low-temperature fluidity. At a target temperature of -70°C, perfluoropolyether lubricant maintains extremely low viscosity, maintaining a stable flow. This effectively prevents circulation blockage caused by oil solidification at low temperatures, ensuring continuous and efficient operation of the pump's vacuum circulation system and perfectly suiting the requirements of simulating low-temperature space environments.

Perfluoropolyether lubricant also exhibits excellent radiation resistance, stably withstanding long-term exposure to X-rays and G-rays. In radiation environments, perfluoropolyether lubricant exhibits no molecular chain breakage or performance degradation, ensuring the chemical stability and service life of the coolant in simulated space radiation environments and reliably guaranteeing the accuracy of experimental data.

For the estimated usage of 50 kg, the high adaptability of this perfluoropolyether lubricant is further highlighted. Its extremely low vapor pressure in a vacuum environment can effectively reduce volatilization losses and avoid the impact of perfluoropolyether lubricant volatilization on vacuum degree. At the same time, the usage of 50KG can meet the long-term operation requirements of small and medium-sized pump circulation systems, taking into account both economy and practicality, and providing key support for the smooth implementation of space capsule environment simulation experiments.
