Description

technical field

[0001] The present invention relates to a dehydrating agent, a pre-washing agent, a dehydrating method and a dehydrating device suitable for removing moisture adhering to the surface of objects to be cleaned after dehydrating precision instruments, optical instruments, electronic instruments and general metal parts. Background technique

[0002] In the case of washing and dehydrating components such as precision instruments, optical instruments, electronic instruments, and general machinery, the method of rinsing with pure water after treatment with an appropriate cleaning agent corresponding to the pollutant is widely used, but in the end It is desirable to remove the water present on the surface of the item being cleaned. Physical methods such as heating, decompression, and centrifugation are used as dehydration means, but dehydration methods using solvents are widely used in view of excellent dehydration performance, low energy consumption and rapid drying...
