Demulsifiers are different from those for daily use and need technology, so generally speaking, demulsifiers are still valuable, because people spend a lot of time and energy to demulsify, especially those demulsifiers independently developed and patented, which are not cheap, but the same, the effect is also very good, and they will not worry about the effect and subsequent service quality.
As for whether to choose the cheap one, there must be many people who will choose it, but even if you choose the cheap one, it depends on the quality. If the effect is not good, you can't buy it even if it is cheap. Buying demulsifier depends on the cost performance, that is, the quality-price ratio. Sennas has a good cost performance, so you can consider it when buying demulsifier.
