Textile, printing and dyeing industry includes cotton, wool, silk, hemp and other natural fibers and synthetic fibers from raw materials to products of a series of processing procedures. In this series of processing procedures, mainly involved in sizing, desizing, scouring, bleaching, dyeing, washing, oil, finishing, printing, impregnation, softening, degumming, to wet and other operations. A...
Before selecting the type defoamer, let's learn the principle of antifoaming agents Principle of defoaming agent Antifoam, also known as defoaming agent, has the following principles: 1. Decrease of local surface tension of foam leads to bubble burst The origin of this mechanism is that high alcohol or vegetable oil is sprinkled on the foam. When it dissolves into th...
No matter pulp process or paper making process, many surfactants are essential for the during production. Surfactants used as cooking AIDS can promote the penetration of cooking liquid to fiber raw materials, enhance the removal of lignin and resin from wood or non-wood, and play the role of dispersing resin. The anionic surfactants used as resin remover include sodium dodecyl benzene s...
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...
Frustrating foam hindrances have been hampering the fermentation productivity. The Fermentation Anti foam is meticulously designed to suppress foam formation, allowing the fermentations to proceed smoothly and efficiently. It effortlessly eliminates excessive foam that can cause numerous operational headaches such as overflow, equipment malfunction, and slow reaction rates.And because the fermenta...
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 ...

Textile dyeing process- Defoamer Foam in dyeing solutions can lead to disastrous consequences such as color spots, stains, and uneven color distribution on fabrics. These undesirable effects can severely compromise the quality of the final product. But worry not, fo...
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...
Black liquor is generally the waste water produced after the caustic soda process is used in papermaking, pulping, washing and other links, which contains a lot of lignin, organic acids, etc., and also contains a part of solid suspended matter. Due to the complexity of the papermaking process, there will be more or less some foam problems in different production links, and if the foam is not ...
