In the modern paper industry, the air and small air bubbles contained in the white water and the slurry have a huge impact on the papermaking of the paper machine, the formation of the paper web, and the quality of the paper after paper production. The generation of air bubbles depends on many reasons, such as the use of wet end chemicals, the jet agitation of stock in the size tank flow system, t...

This product has excellent anti-foam performance, high stability and water dispersion performance. This product is specially designed for cleaning printed circuit boards, can be widely used in the development...
The meaning of fermentation: Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare microbial cells themselves, or direct metabolites or secondary metabolites. Fermentation is sometimes also called fermentation, and its definition varies depending on the occasion in which it is used. Fermentation generally refer...
Industrial cleaning processes often involve the use of various chemicals and detergents to remove contaminants and residues from surfaces. However, during these processes, unwanted foam can be generated, which can hinder the efficiency and effectiveness of the cleaning operation. To address this issue, industrial cleaning defoamers are employed. In this article, we will provide an introduction to ...
Petroleum, known as "black gold", is regarded as a key energy source for economic development due to its rich chemical products and wide range of applications. However, in processing links such as oil refining, once a large amount of foam occurs, this process will become difficult. At this time, the use of petrochemical defoamer can effectively eliminate foam and control foam generation. The main ...
Test defoaming agents before using Before using defoaming agents, you must test them. Otherwise, improper selection may lead to less-than-ideal results or even cause certain harm. We can conduct qualitative or quantitative tests on the performance of defoaming agents according to actual needs. So what are the specific methods for testing defoaming agents? 1. Measuring c...
Factor 1: Surface tension The surface tension of the coating has a greater impact on the antifoam. The surface tension of the antifoam must be lower than the surface tension of the coating; otherwise, it cannot have the effect of defoaming and foam inhibition. The surface tension of the coating is a variable factor, so the choice of antifoam should be constant surface tension, and then the surface...
During the winemaking process, alcohol fermentation produces gas and forms foam. However, excessive foam may interfere with wine production and storage. To solve this problem, people use alcohol fermentation defoamer, which is a chemical specifically designed to control and reduce foam during the fermentation process. The functions of alcohol fermentation defoaming agents are mainly reflect...
