Metalworking Fluid Biocides MBM

Metalworking fluids are often in use for months and years in open circuits of metalworking machines. Left untreated, metalworking fluids can become contaminated with microorganisms. Build-up of bacteria and fungi can cause foul odors, and lead to slime and biofilm that clogs filters and can cause corrosion. Microbial contamination can also lead to dephasing of emulsions, pH drift, and other negative impacts on fluid performance parameters such as lubricity or cooling. An effective biocide treatment plan is essential to help prevent contamination of your metalworking fluids.

Metalworking fluid biocides N,N'-Dimorpholinomethane (MBM), play a crucial role in the metalworking industry. MBM usually appears as a colorless to pale yellow liquid, with a relatively low viscosity, facilitating its easy incorporation into metalworking fluids. Its molecular weight is within a specific range, which influences its solubility and reactivity.

MBM exhibits outstanding antimicrobial activity. It is highly effective against a broad spectrum of microorganisms commonly found in metalworking fluid systems, such as bacteria, fungi, and yeasts. These microbes can cause fluid degradation, foul odors, and reduced tool life. MBM disrupts the cell membranes and metabolic processes of these pathogens, preventing their proliferation and thereby maintaining the integrity and functionality of the metalworking fluid.

 

Performance

One of the remarkable features of MBM is its long-lasting effect. Once added to the fluid, it provides continuous protection over an extended period. This is due to its stable chemical nature, which resists rapid breakdown under the harsh operating conditions of metalworking, including high temperatures, mechanical agitation, and exposure to various metal ions.

It demonstrates excellent compatibility with different types of metalworking fluids, whether they are water-based, oil-based, or semi-synthetic formulations. This means that MBM can be seamlessly integrated without causing any adverse reactions like separation, foaming, or changes in the fluid's rheological properties. This compatibility is essential for ensuring the overall performance of the metalworking fluid blend.

Applications

Machining Operations

In machining processes like milling, turning, drilling, and grinding, MBM-containing metalworking fluids are widely used. The coolant and lubricating properties of the fluid, enhanced by MBM's antimicrobial action, help to dissipate heat generated during cutting, reduce friction between the tool and workpiece, and prevent microbial contamination that could otherwise lead to workpiece surface defects and tool wear.

Automotive Manufacturing

The automotive industry heavily relies on metalworking fluids with MBM for the production of engine components, transmission parts, and chassis elements. The precision and durability required in automotive manufacturing demand clean and effective metalworking fluid systems, and MBM fulfills this need by safeguarding against microbial threats that could compromise the quality of the final products.

 

In conclusion, N,N'-Dimorpholinomethane (MBM) as a metalworking fluid biocide offers a combination of optimal basic parameters, superior performance, and extensive applications. Its role in enhancing the efficiency and quality of metalworking operations cannot be overstated, making it an indispensable component in modern industrial manufacturing.
