Surfactants are often used in industrial industries. For the use of surfactants, most of them are used in washing and textile industries. For all fine industrial industries, they can not leave the use of surfactants. All industries related to our industry, including the pharmaceutical industry, are also inseparable from the use of surfactants, as well as the paper industry, which is also a field of fine industry. Surfactants are also widely used in the paper industry.
In the pharmaceutical industry, the liquid increasing effect of surfactants is often used in pharmaceuticals, which can make many insoluble substances into transparent solutions and increase the concentration of solutions. Moreover, in the pharmaceutical industry, surfactants are also used in the use of fungicides and disinfectants. They can have a strong effect with bacterial biofilm proteins, making bacterial biofilm proteins denatured and even lose their original functions. Therefore, the role of surfactants is very powerful and its application is very extensive.
According to the intensive research of domestic research departments, although there are many kinds of surfactants, the main types developed at present are as follows, which are the types of surfactants frequently used in construction industries such as construction industry:
Hydroxypyridinium chloride is one of the representatives of cationic surfactants. Therefore, this kind of cationic surfactants are classified as cationic after dissociation in water.
Different from cationic surfactants, after dissociation in water, if the anionic group plays a major role, such surfactants are classified as anionic, such as common dialkyl (octyl, hexyl, butyl) sulfosuccinate, castor oil sulfate, sodium pyronaphthalene sulfonate, lauryl sulfate Sodium dodecyl sulfonate is a typical anionic surfactant.
