Magnetic fluid vacuum sealing parts for Vacuum furnace
A ferrofluid has the fluid properties of a liquid and the magnetic properties of a solid. The ferrofluids actually containtiny particles(around 10nm diameter) of a magnetic solid suspended in a liquid medium. To keep them small,magnetic and van der waals interactions must be overcome to prevent the particles from agglomerating. Thermal motion of magnetite particles smaller than 10nm in diameter is suffcient to prevent agglomeration due to magnetic interactions
———The principle of Magnetic sealing
A frroluid can behave as a liquid 0-ring where a rotating shaft enters either a low- or high-pressure chamber. The ferrofluid is held in place bypermanent magnets and forms a tight seal, eliminating most of the friction produced in a traditional mechanical seal .
