Principle and Notes of Ultrasonic Cleaning
As we all know, the sounds people hear are acoustic wave signals with a frequency ranging from 20 Hz to 20,000 Hz. Acoustic waves with a frequency higher than 20,000 Hz are called ultrasonic waves. Acoustic waves propagate longitudinally in the form of a sine wave, alternating between strong and ...Read more -
What are the common functions of surfactants?
Wetting Wetting occurs when a solid comes into contact with a liquid. The original solid-gas and liquid-gas interfaces disappear, and a new solid-liquid interface is formed. For example, textile fibers are porous materials with a large specific surface area. When a solution spreads along the fibe...Read more -
How much do you know about flotation knowledge?
01 Concept of Flotation Flotation, also known as floatation mineral processing, is a mineral separation technology that separates valuable minerals from gangue minerals at gas-liquid-solid interfaces by taking advantage of differences in surface properties of various minerals contained in ores, a...Read more -
Development Trends and Directions of Surfactants for Pesticides
Surfactants function as wetting, dispersing, emulsifying and solubilizing agents in pesticide processing and have become indispensable components of pesticide formulations. They are also commonly referred to as auxiliary agents, emulsifiers, dispersants and adjuvants, which can be compound blends...Read more -
Characteristics of commonly used surfactants in detergents
Surfactants There are numerous types of surfactants. Ranked by output, anionic surfactants account for 56%, nonionic surfactants 36%, amphoteric surfactants 5%, and cationic surfactants 3%.. 2.Anionic Surfactants 2.1 Sulfonate-type Anionic Surfactants Common types of such surfactants include so...Read more -
Selection Principles of Surfactants for Spray Cleaning Agents
I. Methods to Make Cleaning Agents for Spray Cleaning Low-Foam or Foam-Free Add defoamers: Commonly used types include silane-based defoamers, polyether-based defoamers and low-molecular-weight alcohol-based defoamers. Select appropriate surfactants. II. Three Main Methods for Surfactant Selecti...Read more -
Dish Soap and Surfactants
1.Introduction With the development of the chemical industry, people’s living standards have been continuously improved. While life has been greatly enhanced, it has also caused severe environmental problems, even endangering human health and safety. As people’s demands for health kee...Read more -
Overview of the Safety of Surfactants
Safety of Surfactants Surfactants and their metabolites induce biological changes in the organism, namely potential toxic and side effects on the body, including acute toxicity, subacute toxicity, chronic toxicity, impacts on fertility and reproduction, embryonic toxicity, teratogenicity, mutagen...Read more -
The “three siblings” of aliphatic amines: primary, secondary and tertiary
Aliphatic amines refer to a large class of organic amine compounds in which the hydrogen atoms of ammonia molecules are substituted by aliphatic alkyl groups with a carbon chain length ranging from C8 to C22. In ancient times, siblings were traditionally ranked in the order of Bo, Zhong, Shu and ...Read more -
Laundry Detergent Formula Technology
Detergents are specially formulated products for cleaning. On the market, laundry powder and laundry liquid are the most commonly used products for washing clothes. Laundry powder cannot dissolve completely during use; its residues may easily damage clothes and are difficult to rinse off. In cont...Read more -
Application of Low-Foam Surfactants in Industrial Cleaning
In industrial cleaning, foam not only impairs detergency but also makes rinsing difficult, tends to leave residues, and may even overflow from cleaning equipment, resulting in waste. Additionally, foam can strip surfactants from the cleaning liquid phase. Therefore, low-foam cleaning products are...Read more -
Instability manifestations of emulsions (flocculation, coalescence, stratification and demulsification)
There are several manifestations of emulsion instability: flocculation, coalescence, stratification (or sedimentation), demulsification, phase inversion and Ostwald ripening. 1.Flocculation The dispersed droplets in the emulsion aggregate to form clusters of three-dimensional droplets, which are...Read more
