Definitions
- the invention relates to a method for cleaning industrially manufactured parts made of metal and / or plastic.
- the invention relates to a device for cleaning of industrially manufactured parts made of metal and / or plastic, in particular to r Du rchSystemu ng of the method according to the invention.
- the invention has the object of specifying a method and a device of the type mentioned above with which an improved cleaning experience can be achieved in a shorter time and with less effort.
- An inventive method for cleaning of industrially manufactured parts from metal and / or plastic using a cleaning agent is characterized in that a mixture of at least two organic solvents and water is used as the cleaning agent, which mixture does not interfere with at least one water-soluble organic solvent and at least one water-soluble organic solvent.
- a mixture of at least two organic solvents and water is used as the cleaning agent, which mixture does not interfere with at least one water-soluble organic solvent and at least one water-soluble organic solvent.
- the method includes the following steps: a) introducing parts to be cleaned into a working chamber; b) loading the working chamber with water and with a solvent mixture containing at least one first water-insoluble organic solvent and at least one second water-soluble organic solvent;
- a device for cleaning industrially manufactured parts made of metal and / or plastic, in particular for the purpose of carrying out the method according to the invention, comprising: a) a working chamber for receiving parts to be cleaned;
- Tan kstoff to m providing water and a solvent mixture containing at least a first water-insoluble, organic solvent and at least one second wasserlösl iches, organic solvent, which tank means to m the loading of the working chamber with the water and the solvent mixture with the working chamber in Flu idriv stand;
- a cleaning agent according to the invention a mixture of at least two organic solvents and water is used.
- the water-solvent mixture or the cleaning agent in addition still contains a clean ing amplifier, such as a surfactant and / or an amine. In this way, the cleaning effect can be strengthened in a conventional manner.
- E ine another development of the method according to the invention provides that in Sch ritt c) a rolling of the parts and / or the water-solvent mixture in the working chamber takes place in order to improve the cleaning effect and to this end a dispersion (with liquid components specifically an emulsion) of the components of the water-solvent mixture.
- the parts are removed from the working chamber or the water-solvent mixture (the cleaning agent) is discharged from the working chamber at the end of step c).
