Impregnating Oil Implementation Examples

Problems and background before implementation

The non-user-friendliness of liquid grease increases the cost and destabilizes the performance.

Liquid grease containing thickener is being used as impregnating lubricant. However, its relatively high viscosity prevents metal flakes from settling, causing the flakes to be adhered to the surface of the impregnated metal.
When used repeatedly for impregnating, the liquid grease exhibits increased relative viscosity, which changes the amount of lubricating ingredient adhered.
Due to these problems, the liquid grease, having been used for impregnating to some extent and having increased viscosity, is usually wasted, leading to additional cost.

Solution

Problems are solved by simply changing to high-performance oil, FLOIL 917P, which contains no thickener.

Liquid grease is considered to have improved durability with the effect of thickener ingredient. However, this state-of-the-art oil can achieve the durability, comparable to that achieved by liquid grease, by choosing the type and amount of additives.
This highly durable oil allows the settling of metal flakes suspended in the oil after the impregnating and prevents their adhesion to the metals.
Since the oil does not contain thickener and the additives are dissolved in the oil, no segregation occurs in the adhered components even when used for repeated impregnating, which enables stable performance.

Implementation effects

It improves the stability of product performance and reduces cost.

There is neither spontaneous precipitation of metal flakes, nor segregation of ingredient and adhered amount, which improves the product stability of impregnated metals. Since the oil can be used until the use limit of impregnated device, which eliminates unnecessary disposal cost and achieves cost reduction.
