Classification and Development Direction of Phosphating Agent

Phosphating agent is divided into iron phosphating agent, zinc phosphating agent and zinc manganese phosphating solution, each product has its different characteristics. 1. Iron phosphating agent, color phosphorus, we sometimes call iron coating agent. The iron-based phosphating agent has low cost, good stability and less pollution; the solubility product of iron phosphate is very small (Ksp = 1.3X10-2), and it can quickly precipitate from the liquid phase with high acidity at low temperature. Moreover, the phosphating liquid film has low porosity and good adhesion to paint, which is an excellent coating bottom layer, so iron-based phosphating is a very promising phosphating process.

Classification of Phosphating and Influence of Phosphating Wastewater on Environment

Pickling and phosphating wastewater is commonly found in electrophoresis, spraying, chemical industry, electroplating and other enterprises, and its pollutants are complex and changeable. Due to their different production processes, some also contain a certain amount of heavy metals such as nickel ions, copper ions or lead ions, as well as surfactants and other pollutants, which are extremely harmful. Moreover, phosphorus can cause eutrophication of water bodies, make the oxygen content of water bodies drop rapidly, and seriously endanger the ecological environment. (Generally speaking, when the total phosphorus content in the water reaches 20mg/L, it is considered eutrophication).

What is wax removal water, this article tells you

Wax removal water as an active substance, supplemented by a certain metal corrosion inhibitor, wax removal water as a multifunctional cleaner, can emulsify waxy dirt and have a certain cleaning effect on oil. The key point of its preparation lies in the reasonable compounding of various active compounds and corrosion inhibitors, by reducing the surface tension of the target object, improving the penetration performance and emulsifying dissolution, so as to strengthen the penetration ability to achieve the purpose of wax removal.

Application of degreasing powder

Degreasing powder scope of application: suitable for stainless steel, ferrous metals, non-ferrous metals and other metal materials. Can be used for metal thermal processing and stamping formed by heavy dirt, black glue, carbon deposits, oil and other cleaning. It can effectively with the metal processing process formed in the heavy scale, black glue, carbon deposition, oil reaction and separation and removal.

The principle of degreasing powder

Oil pollution can be divided into saponified oil and non-saponified oil. Animal and vegetable oil belongs to saponified oil pollution and alkali saponification reaction, while mineral oil belongs to non-saponified oil pollution and alkali saponification reaction. Oil removal powder cleans oil pollution from the surface of the workpiece through the dual action principle of alkaline saponification and surfactant emulsification.
