Surface active agent is usually divided into two categories: Cattea surface active agent: It mainly reduces the surface tension of liquid through the action of positive ions and increases the contact ability of liquid and solid. Common cations surface active agents include hexisanelxyl tritenium bromide (CTAB), hexisanel trimethylsonium chloride (CTAC). Non -ion surface active agent:…

Surface active agents in detergent are generally safe for the human body under normal use. However, they may cause minor allergies or stimuli reactions to some people. Therefore, when using detergent, it is recommended to follow the following points: Avoid long -term contact: try to avoid long -term contact with dishwashing or expose it directly…

Fundamental is a chemical for water treatment and wastewater treatment. It can help remove solid particles and suspension of suspended solids in water, so that it can gather large blocks to facilitate subsequent separation and precipitation. The mechanism of the flocculant can be explained through two processes: flocculation and condensation. Society refers to attracting tiny…
The principle of surfactant sterilization is mainly to achieve the effect of sterilization by destroying the cell membrane structure and interference of its metabolic function. The specific principles are as follows: 1. Destroy bacterial cell membrane: Surface active agents have both the characteristics of hydrophobic and hydrophilic. Its molecular structure also contains hydrophobic groups and…
Surface active agent is a chemical that can reduce liquid surface tension. They are composed of a hydrophilic (like water) head and a hydrophobic (do not like water) tail. During the pollution process, the hydrophobic tail of the surfactant will be adsorbed to the surface of dirt, while the hydrophilic head interacts with water molecules….

The principle of the function of flocculant is to condense the properties of the material in the solution, so that the tiny particles that suspend the solution in the solution are concentrated into large blocks, which is convenient for precipitation or filtering. Flocculants are usually polymer compounds. They have polar groups or contain a large…
The precipitant and flocculant are used for chemical agents during water treatment, which are used to remove suspended particulate matter and turbid substances. Their mechanisms and methods of use are slightly different. 1. Mechanism: -Setal: The precipitant reacts the chemical reaction with the suspended particulate matter, forming a large sediment, so that the suspended objects…

Surface active agent is a type of compound with a certain solubility and interface activity. It can reduce the tension of liquid surface in the solution and form a layer of film on the liquid-liquid or liquid-solid interface. performance. According to the chemical structure and solubility of the surfactant, it can be divided into two…
The four major functions of surfactants include: 1. Reduce surface tension: Surface active agents can reduce the tension of liquid surface, so that liquids are more likely to expand or penetrate into small pores when they come into contact with solid or other liquids, and improve the moisturizing performance of the liquid. 2. Diversified stability:…
