Description

Technical Field

[0001] The utility model relates to the technical field of surfactant proportioning equipment, in particular to a raw material proportioning device for surfactant processing. Background Art

[0002] Surfactants are mainly amphiphilic molecules, which are both hydrophilic and lipophilic, but not completely hydrophilic or lipophilic. They exhibit unique interfacial activity, which achieves a certain balance between hydrophobic groups and hydrophilic groups. Surfactant formulas are different according to different uses. The main components of anionic surfactant formulas are stearic acid, sodium dodecylbenzene sulfonate, etc., the main components of cationic surfactants are quaternary ammonium compounds, zwitterionic surfactants mainly include lecithin, amino acid type, betaine type, etc., and the main components of non-ionic surfactant formulas are: fatty acid glycerides, fatty acid sorbitan, polysorbate, etc. When processing surfactants, it is necessary to proportion a variety of formula raw materials and then stir and mix them. Unlike other liquid proportions, the main ingredients of surfactants account for a large proportion, while the auxiliary ingredients account for a small proportion, so accuracy needs to be ensured when proportioning.
