I just want to ask: do you know why foam forms? A large part of it is to be blamed on one’s own way of operating. First of all, we need to understand one thing: even when water is forced through at high pressure, foam can still form. So in some cases, it’s not the product itself that’s to blame – there’s an issue with the way it’s being used. Of course, if you buy some really unreliable cutting fluid from Suzhou, then you’re just creating problems for yourself. The main reasons for foam formation when using cutting fluids in Suzhou are as follows: First, as mentioned earlier, if the pressing force is too high and the flow rate is excessive, this can lead to foam formation. Second, if the filter mesh used is too fine, filtration will be slow; since water flows in quickly, this back-and-forth movement can result in foam formation. The third point is that the cutting fluid used in Suzhou has deteriorated. We will discuss the issue of cutting fluid deterioration in Suzhou another time. The fourth point is that the antifoam agents used have a short lifespan and poor stability. Jingshen Lubricants, a brand of cutting fluid from Suzhou, reminds you to always keep an eye on the condition of the cutting fluid used in your machinery; replace it immediately if it deteriorates, and address any foaming issues right away. Only in this way can you ensure the longevity of your machine tools.
