defoamer-antifoam

Global defoamer market trends According to statistics, the global defoamers market was worth US$3.2 billion in 2018, and the compound annual growth rate is expected to be 4.8% between 2019 and 2025. The increasing use of defoamers in a variety of agrochemicals such as fertilizers and pesticides, as well as the significant growth of water treatment infrastructure, have promoted the development of this market. Defoamers play an important role in reducing the carbon footprint caused by manufacturers and end users, which may drive the demand for low VoC solvent-free defoamers. Manufacturers emphasize the use of bio-based and sustainable raw materials, rather than petroleum-based variants. On the other hand, manufacturers emphasize the development of modified and high-performance organosilicon compounds to improve product performance. North America defoamers market size, by product, 2018-2025(USD million)   Due to the low c...

How to choose defoamer for fermentation accordingly? Foam is a phenomenon often encountered in daily life and industrial and agricultural production. In industrial and agricultural production, sometimes foam is needed in production, and then foam needs to be produced in production; sometimes foam is not needed in production, and foam needs to be eliminated at this time. Foam refers to a gas-liquid dispersion system in which a gas is dispersed in a liquid, the gas is a dispersed phase, and the liquid is a dispersion medium. Pure liquids are difficult to form foam, because there is only a very thin layer of water film between the foams. This layer of water film is very unstable and easily damaged. The blister life of pure water is within 0.5 s. Therefore, it is difficult to generate foam. Only with the addition of surfactants or high molecular compounds can a stable foam be formed. How to foam generation The creation of a bubble must meet two conditions: Gas-liquid two-ph...

How to add defoamer/antifoam and Tips using defoamer Adding Method 1) Gap addition- common method If it is not continuous foaming and the foaming is not severe, the antifoaming agent may be added once or periodically. Since the amount of the antifoaming agent added is small, in order to make the antifoaming agent uniformly dispersed, it should be added in a place where the foaming liquid is drastically shaken. Many occasions can be added by hand. If the blister is violent or for rapid defoaming, it can be sprayed with a spray gun. If foam is allowed to exist within certain limits, just to prevent excessive foaming, an insoluble, high-efficiency silicone paste defoamer may be applied to the upper edge of the wall of the container or applied to a metal mesh or other textile mesh. Above, cover a certain position of the container. The foam layer is exposed to the silicone defoamer and can be broken, thereby blocking the foam from overflowing. Not enough to add once, you can join ...

Nanjing Invelychem has developed a defoamer (anti-foaming agent); Invely-0030, which exhibits a superior defoaming property in the sugarcane ethanol production process. 【 Background of the development 】 Amid the taking measures against global warming, bioethanol is considered a green alternative to gasoline that does not affect the total amount of CO 2 in the atmosphere. It is expected to be carbon-neutral biofuel and its use has been steadily increasing mainly in U.S. and Brazil. Bioethanol is produced from feedstock crops such as sugarcanes and corns via alcoholic fermentation. Especially sugarcanes give very high bioethanol yield per unit of land; thus bioethanol has been already widely used in Brazil where the largest amount of sugarcane is produced worldwide. Bioethanol is produced by a decomposition of sugar to ethanol and carbon dioxide through alcoholic fermentation using yeast. Carbon dioxide generated during the fermentation process creates a lot of foams, and t...
