The principle and application of demulsifiers
Due to the low solubility of certain solids in water, when one or several of these solids are present in large quantities in an aqueous solution and are agitated by hydraulic or external forces, they can exist in a state of emulsification within the water, forming an emulsion. Theoretically, such...Read more -
Principles of Leveling Agents
Overview of Leveling After the application of coatings, there is a process of flow and drying into a film, which gradually forms a smooth, even, and uniform coating. The ability of the coating to achieve a flat and smooth surface is referred to as leveling property. In practical coating appli...Read more -
Do you know what types of pesticide adjuvants there are?
Adjuvants That Enhance or Prolong Drug Efficacy ·Synergists Compounds that are biologically inactive themselves but can inhibit detoxifying enzymes in organisms. When mixed with certain pesticides, they can significantly enhance the toxicity and efficacy of the pesticides. Examples include syner...Read more -
Do you know what types of pesticide adjuvants there are?
Pesticide Adjuvants are auxiliary substances added during the processing or application of pesticide formulations to improve their physicochemical properties, also known as pesticide adjuncts. While adjuvants themselves generally have little to no biological activity, they can significantly influ...Read more -
What method can be used in Corrosion Prevention?
In general, corrosion prevention methods can be divided into two main categories: 1.Correct selection of corrosion-resistant materials and other preventive measures. 2.Choosing reasonable process operations and equipment structures. Strictly adhering to the process regulations in chemical pr...Read more -
What’s the Functions of Surfactants？
1.Wetting action (Required HLB: 7-9) Wetting refers to the phenomenon where the gas adsorbed on a solid surface is replaced by a liquid. Substances that enhance this replacement capability are called wetting agents.Wetting is generally divided into three types: contact wetting (adhesion wetting)...Read more -
What are the applications of surfactants in oilfield production?
1.Surfactants for Heavy Oil Extraction Due to the high viscosity and poor fluidity of heavy oil, its extraction poses significant challenges. To recover such heavy oil, an aqueous solution of surfactants is sometimes injected into the wellbore to transform the highly viscous crude into a l...Read more -
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
