Defoamer is a substance with lower surface tension and higher surface activity that can inhibit or eliminate foam in the system. In the industrial production process, a lot of harmful foams will be produced, which seriously hinders the progress of production. At this time, it is necessary to add antifoaming agents to eliminate these harmful foams. Defoamer is widely used and can be used to eliminate harmful foams in the production process of latex, textile sizing, coatings, petrochemicals, papermaking, industrial cleaning, and other industries.
In the process of using the defoamer, many customers will encounter the situation that the defoamer needs to be diluted, and the thickener must be used for thinning. So, what kind of thickener should I choose in the defoamer?
1. Thickeners with good stability should be selected. Some thickeners have good thickening effect at that time. However, it will liquefy after a period of time. As a result, water will be water and emulsion will be emulsion, which is what we often call layering or demulsification, which will seriously affect the quality of defoamer.
2. To choose a thickener that is easy to use, some thickeners are extremely difficult to use. It needs to be added to the water in an amount and dissolved for a long time before it can be used. waste time. Some use a high-speed disperser to stir for a long time to have a good uniform thickening effect, and some powder thickeners are not well stirred. There will be clumping phenomenon, which will seriously affect the product quality. Therefore, it is best to choose a thickener that is easy to use and quickly dissolves and thickens.
3. To choose a thickener with stable quality, some thickeners themselves are of very unstable quality, and a batch may thicken well. A batch may be very different, and the quality of the product will be seriously affected when used.
4. To choose a thickener with low cost of use, some thickeners are very cheap, but the amount added is large, and the cost of use is high. Some thickeners are more expensive, but the addition amount is small and the effect is good. On the contrary, the cost of use has dropped a lot.
5. There is no best thickener, only the most suitable. To choose the most suitable thickener, the best effect, the lowest cost, and the most convenient thickener for one's own product, it is necessary to make a small trial with the user before confirming.
6. Don't choose the most expensive or the cheapest, only choose the most suitable thickener to help thicken our water-based defoamer, thereby improving the stability, appearance and quality of the defoamer.
