Choose the right thickener when defoamer is diluted
In the process of using defoamers, how many times will defoamers need to be diluted. Thickener should be used in dilution. So how to choose the right thickener?
1. Good stability
Some thickeners had good thickening effect at that time. But after a period of time, it will liquefy and turn water into water. The emulsion is the emulsion, which is what we often say is delamination or demulsification, which seriously affects the quality of defoamer.
2. Easy to use
Some thickeners are extremely difficult to use. It needs to be added to the water in quantities, and it can be dissolved for a long time before it can be used. Waste time. Some need to be stirred with high-speed disperser for a long time to have a good uniform thickening effect, some powder thickeners, mixing poorly, there will be clumping phenomenon, seriously affecting product quality. So it's better to choose a thickener which is easy to use and can dissolve quickly.
3. Quality stability
The quality of some thickeners is very unstable, and a batch of thickeners may be very good. A batch may be far from each other, and the quality of the product will be seriously affected when it is used.
4. Low cost of use
Some thickeners are very cheap, but the amount of them is very large, so the cost of using them is high. Some of the thickeners are more expensive, but the addition amount is small and the effect is good. On the contrary, the cost of using them decreases a lot.
Fifth, there is no best, only the most suitable.
To choose the most suitable thickener for your product, the best effect, the lowest use cost and the most convenient use, you need to use a small home test and then determine.
To sum up, we choose defoamer not the most expensive, nor the cheapest, but the most suitable thickener to help our water-borne defoamer thicken, so as to improve the stability, appearance, and quality of defoamer.
