To prevent coolant fluid deterioration
Since coolant fluid is a consumable, it will eventually deteriorate with use, but are there any measures to prevent this? In this section, we will explain the causes of coolant degradation and how to deal with it.
Main causes of coolant degradation
The main reasons for coolant fluid degradation are as follows
Chips retained in coolant tank
When cutting is performed on a machine tool, a large amount of metal chips called swarf is generated. These chips get mixed in the coolant solution and remain in the tank. If left unchecked, the components eluted from the chips and the coolant fluid can cause a chemical reaction and become sludge.Accumulation of sludge leads to deterioration of the coolant fluid, which may result in ineffective cooling and lubrication.
Other oil gets mixed in the coolant liquid
At sites with machine tools, a variety of oils are used, such as lubricating oil, hydraulic oil, and pre-processing oil. However,When these are mixed in the coolant solution, they accelerate contamination and deterioration, resulting in reduced performance.The required effect may not be achieved.
Decay due to microbial growth
Coolant fluid, which often comes in contact with the outside air, is prone to the entry of microorganisms.The presence of sludge and other oils in the coolant tank provides food for microorganisms, and their growth leads to deterioration and decay of the coolant fluid.This results in foul odors and shortened coolant life.
How to prevent coolant fluid deterioration
Install equipment such as chip conveyors and filters
To prevent coolant fluid deterioration, it is important not to allow chips to remain in the tank.For this purpose, it is recommended to install equipment such as chip conveyors to discharge chips to the outside and filters to filter chips and keep coolant fluid normal.
Clean the tank regularly.
Even when chip conveyors and filters are used, fine chips and foreign matter inevitably remain. Therefore,It is important to clean the tank regularly to remove deposited chips.In this way, the coolant fluid life can be extended.
Use appropriate additives
To prevent coolant fluid from decomposing, it is effective to use preservatives and mold inhibitors that inhibit microbial growth.The use of appropriate additives can help keep coolant fluid in good working order and reduce the frequency of filter and periodic replacement.
Editor's Summary
To prevent deterioration of coolant fluid and prolong its life, it is important to prevent chips and other oils from getting mixed in and to remove them properly. Coolant filtration equipment is recommended as a device for this purpose. This site also introduces recommended products for your environment and needs, so please check it out.
