Banishing bacteria

sealing solutions will all be presented under the Henkel umbrella. However, at MACH, Multan will take centre stage with its comprehensive range of cutting fluids and stamping and drawing fluids.

Bacterial contamination is a natural biological process in the life of a cutting fluid. However, not only does this process cause a bad odour but ultimately results in the emulsion splitting and becoming unusable. Historically there have been two ways of avoiding these problems.

The first option was to add bactericides to conventional fluids when the bacterial growth exceeded a given level. The problem here is the resultant dead microorganisms effectively feed the new generation of bacteria so that remedial action has to be repeated at ever shorter intervals. The second option is to use fluids that contain bactericides, which permanently suppress bacterial growth.

In both cases, the use of bactericides has to be viewed critically. Exposure to bacteria or bactericides represents a potential health hazard for employees who may develop skin irritations or increased sensitisation after contact. Frequent changing of emulsions that have split is not only very costly but puts an additional burden on the environment.

Henkel will be focusing on its sustainable solution to this cutting fluid problem with the patented emulsifier technology of its Multan 71-2 fluid, formulated for a range of machining applications. A product of intensive development work, this is a microbiologically robust cutting fluid that contains no bactericides or requires any later addition of bactericides to keep it stable.
