What are the applications of biosurfactants in environmental engineering?
Many chemically synthesized surfactants damage the ecological environment due to their poor biodegradability, toxicity, and tendency to accumulate in ecosystems. In contrast, biological surfactants—characterized by easy biodegradability and non-toxicity to ecological systems—are better suited for...Read more -
What are biosurfactants?
Biosurfactants are metabolites secreted by microorganisms during their metabolic processes under specific cultivation conditions. Compared with chemically synthesized surfactants, biosurfactants possess many unique attributes, such as structural diversity, biodegradability, broad biological activ...Read more -
What specific roles do surfactants play in various cleaning applications?
1. Application in Chelating Cleaning Chelating agents, also known as complexing agents or ligands, utilize the complexation (coordination) or chelation of various chelating agents (including complexing agents) with scaling ions to generate soluble complexes (coordination compounds) for cleaning p...Read more -
What role do surfactants play in Alkaline cleaning applications
1. General Equipment Cleaning Alkaline cleaning is a method that uses strongly alkaline chemicals as cleaning agents to loosen, emulsify, and disperse fouling inside metal equipment. It is often used as a pretreatment for acid cleaning to remove oil from the system and equipment or to convert dif...Read more -
What specific roles do surfactants play in pickling cleaning applications?
1 As Acid Mist Inhibitors During pickling, hydrochloric acid, sulfuric acid, or nitric acid inevitably react with the metal substrate while reacting with rust and scale, generating heat and producing large amounts of acid mist. Adding surfactants to the pickling solution, due to the action of the...Read more -
What are the applications of surfactants in chemical cleaning?
During industrial production processes, various types of fouling, such as coking, oil residues, scale, sediments, and corrosive deposits, accumulate in the equipment and pipelines of production systems. These deposits often lead to equipment and pipeline failures, reduced efficiency of production...Read more -
In which areas can flotation applied?
Ore dressing is a production operation that prepares raw materials for metal smelting and the chemical industry. Froth flotation has become one of the most important methods of mineral processing. Almost all mineral resources can be separated using flotation. Flotation is currently widely applied...Read more -
How does the oil demulsifier work？
The mechanism of crude oil demulsifiers is based on phase inversion-reverse deformation theory. After adding the demulsifier, a phase inversion occurs, generating surfactants that produce the opposite emulsion type to that formed by the emulsifier (reverse demulsifier). ...Read more -
How should we clean oil stains from metal parts?
Prolonged use of mechanical parts and equipment will inevitably lead to oil stains and contaminants adhering to the components. Oil stains on metal parts are typically a mixture of grease, dust, rust, and other residues, which are usually difficult to dilute or dissolve ...Read more -
What are the applications of surfactants in the oilfield sector?
According to the classification method of oilfield chemicals, surfactants for oilfield use can be categorized by application into drilling surfactants, production surfactants, enhanced oil recovery surfactants, oil and gas gathering/transportation surfactants, and water ...Read more -
What are the applications of surfactants in agriculture?
Application of Surfactants in Fertilizers Preventing fertilizer caking: With the development of the fertilizer industry, increased fertilization levels, and growing environmental awareness, society has imposed higher demands on fertilizer production processes and product performance. The applica...Read more -
What are the applications of surfactants in coatings?
Surfactants are a class of compounds with unique molecular structures that can align at interfaces or surfaces, significantly altering surface tension or interfacial properties. In the coatings industry, surfactants play a crucial role in various applications, including ...Read more
