defoamer-antifoam

What is a silicone defoamer ? Why can silicone work to break foam? The defoamers must be able to reduce the surface tension to break foam in order to control foam, Compared with most other foam control materials, silicone has lower surface tension and interfacial tension, it is difficult to be dissolved by surfactants commonly used in the system. At the same time, compared with glycol-based or mineral oil-based defoamers, the toxicity is relatively low. What are the advantages of silicone defoamers? Is it suitable for corrosive conditions? Silicone defoamers can ensure efficient and lasting effect. Silicone defoamers are very safe. Many categories meet the requirements of the US Food and Drug Administration (FDA), the US Environmental Protection Agency (EPA), the US Department of Pesticides (USDA) and other regulations , Low surface tension, can effectively control the generation of foam in a variety of foaming materials. There are a variety of defoamers that can perform well under var...

The global papermaking chemicals market will exceed 42 billion US dollars in 2025 Relevant data show that the global papermaking chemicals market will exceed 42 billion US dollars in 2025. Papermaking chemicals as follow: process chemicals, functional chemicals, pulping chemicals on the other hand by type, they can be divided into special chemicals, commodity chemicals, etc. Papermaking chemicals are specifically used to change paper properties, including color, strength, recycling performance, basis weight, quality, and related attributes. In order to obtain specific functions, the paper undergoes various processes such as bleaching, beating, strengthening and sizing. In order to further improve paper quality and improve multiple functions, people in the industry continue to improve the performance of paper, and it is expected that the scale of the chemical industry will be further promoted in the next few years. Why does paper chemicals has been increasing? As the pursuit of paper fi...

How should we select defoamers / antifoams for paper pulp? Pulp and paper antifoaming agents is very necessary in papermaking, because a lot of foam will be generated in the process of papermaking and pulping, the surface tension of the generated saponification is less than the surface tension of black liquor produced by cooking materials, making it It exists in the surface layer of black liquor and forms a thin film, which forms foam under the mixing action of air. The papermaking process is mainly divided into two major steps,  Washing pulp Papermaking No matter which step inevitably produces foam, so you need to use defoamers/antifoam for paper industry, there are many types of defoamers, the following is for everyone Introduce the characteristics of papermaking defoamers. Excessive foaming will result in the loss of fibers and raw materials. Further, the presence of air in the wet paper web can affect the filtration rate of paper in the paper making pulp defoamers is a better s...

The epidemic situation of the new coronavirus in China has been effectively controlled, but coronavirus has already broken out in other regions of the world. In addition to our country, Italy has also set up blockade and isolation measures. Potential negative demand impact-FMCG growth slows Worries about the virus are likely to affect consumer consumption patterns. From the perspective of pulp and paper, this trend will most directly affect packaging demand. In the past, the post-holiday recovery difficulties caused by the virus in our country, the large-scale loss and even the closure of the tertiary industry such as catering, tourism, and supermarkets, as the virus entered other major countries (the Western country ’s tertiary industry accounted for a larger proportion May be more prominent), consumers may exhibit similar behavior. Trend chart of the proportion of employment of tertiary industry in China   Trend char...
