Defoamer is an additive to remove foam. In the production and application process of coating, textile, medicine, fermentation, paper, water treatment and oil chemical industry, a lot foams will be produced, which will affect the product quality and production process. Based on the suppression and elimination of foam, a specific amount of defoamer is usually added to the production. Defoamer i...
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 ...
In order to improve the cleaning effect and remove impurities from the surface of the steel plate during cleaning, chemical additives such as cleaning agents are added. However, it is easy to produce a lot of foam under high-pressure washing, so it will be used with steel plate cleaning antifoams. The main reason why foam appears during steel plate cleaning is that the steel plate cleaning agent c...
In the pulping and papermaking process, a series of operations after cooking and discharging, such as washing, screening, bleaching, concentration, pulp supply system, surface sizing, coating, black liquor recovery, etc., are all affected by foam to varying degrees. Today Rickman will mainly share with you surface sizing. What is surface sizing? Surface sizing is a procedure in the paper proc...
