The stability of an emulsion defoamer hinges upon a carefully balanced interplay between specific concentrations of emulsifiers and the application of cutting-edge stabilization techniques. Remarkably, despite the inherently thermodynamically unstable nature of the oily substances within an emulsion, the presence of an optimal quantity of emulsifier stabilizers endows the emulsion with relative st...
Advantage of type defoamers for pulp and paper Type of defoamer Advantage Grease Breaking foam quickly Silicone Fast antifoaming performance Fatty ALohol Strong degassing performance, low unit price, minimal impact on sizing Polyether (ester) Fast defoaming and excellent foam inhibiting performance Harm of excessive foam in pulping process: 1. The generation of foam leads to the decrease of ...
Hazard of bubbling in circulating water treatment (1) Excessive foam leads to thorough sewage treatment, which cannot meet the detection standards of environmental Protection Bureau, and can not be discharged, slowing down the process; (2) Too much foam spills over from the surface, causing serious pollution of the external environment; (3) too much foam, water treatment appearance is too ugly; (4...
With the development of modern science and technology, high quality and high efficiency are required for pesticide industry.That is, the formulation of pesticides should use a variety of additives, including additives to help the active drug wetting and dispersion;There are additives to improve the storage stability of pesticide products;There are also auxiliaries that achieve specific functions. ...
More and More companies who are traders , know how to choose the type of defoamers in papermaking process. However , how to evaluate defoamer’s performance in papermaking process, they just do some lab in simple test by eye observing the foam. It works but is not comprehensive. In order to evaluate comprehensively, you need to know the air content measure, which is mainly used to detect the ...
Wastewater discharged during the production process of the paper industry. Paper industry wastewater can be divided into sulfate pulp wastewater and sulfite pulp wastewater. Among them, the waste water discharged from the pulp process is the most serious pollution. What's more, a large number of foams will be generated in the treatment process, paper wastewater will contain a large number of impur...
A metalworking fluid defoamer is a special additive used to inhibit foam generation during metalworking processes. It is commonly added to metalworking fluids such as cutting oils, coolants, and grinding fluids to improve the surface tension of the fluid, eliminate foaming, and improve the fluid's cooling and lubricating properties. How do metalworking fluid defoamers work? Metalworking fluid defo...
China's demand for pesticides is also very large, pesticides are used in agriculture specifically for the control of pests and diseases and the regulation of plant growth of the chemical agents, pesticides in the process of use will now produce more foam, and the production of these bubbles will be mixed with the air to affect the efficacy of the product, but also lead to the reaction of the liqui...
