Surfactants, as molecules with hydrophilic and lipophilic groups, can play a solubilizing role in solutions. The solubilization mechanism mainly includes the following aspects: Reducing surface tension: Surfactants can form a thin film on the surface of a liquid and reduce its surface tension by adsorbing at the interface. This can better mix non polar substances…
When the flocculant is used excessively or the concentration is too high, it may cause some problems, such as an increase in sediment and an increase in solution viscosity. In response to this situation, the following handling methods can be considered: Dilution solution: Dilute the solution containing a high concentration of flocculant appropriately to reduce…
PBTCA, also known as 2-phosphosuccinic acid, is a chelating agent commonly used in industries such as water treatment, metallurgy, textiles, and leather. Its main functions are as follows: Scale prevention: PBTCA can combine with metal ions such as calcium, magnesium, and iron in water to form stable complexes, thereby preventing their precipitation and scaling. In…
Acid pickling corrosion inhibitor BTA, also known as benzyl triamino acid, is a commonly used metal pickling corrosion inhibitor. Here is the usage of BTA: Pre treatment: Before acid pickling, the metal surface needs to be pre treated. Firstly, clean the metal surface to remove impurities such as grease, dirt, and oxides. Alkaline cleaning agents…
