METAL DEGREASING SOLVENTS – SELECTING THE RIGHT ONE

The critical choice of solvent and consequently the corresponding cleaning system will depend upon the solvent’s compatibility with the contaminants to be removed.

In particular the question of contaminant type will largely dictate the route. The distinction between organic and inorganic as well as polar and non-polar will be important points for consideration. Organic impurities such as oil, grease and wax will be readily dissolved by perchloroethylene. Inorganic matter such as mineral content which demonstrate polar characteristics will benefit from the capability of RG63 modified alcohol to hold a percentage of water in solution.

The importance of correct solvent choice cannot be over emphasised. In order to guarantee correct selection Firbimatic Spa offers trial cleaning at its premises in Bologna, Italy. However, this forms only part of the picture.

In order to establish long term suitability and compatibility, Standard Industrial Cleaning Systems will call on the services of its sister company Geiss UK Ltd for solvent /contaminant compatibility tests which are carried out at the analytical laboratory of Richard Geiss GmbH in Germany. Furthermore, long term results and performance can be evaluated by distillation analysis or “cooking tests.” This service is now unique within the industrial cleaning and degreasing industries.

All systems from the Firbimatic range operate entirely under vacuum. This ensures major advantages for the operator:

  • Massively reduced solvent losses /consumption.
  • Lower operating temperatures which reduce solvent “stress”, maintain solvent stability and improve recovery in the drying phase.
  • Reduced energy consumption.
