Metal Degreasing Agent Stable nature

Metal degreasing agent and our lives are closely related, then we understand how much it, the following to tell you about the characteristics of metal degreasing agent products, please read the following article carefully.

1, the agent for the white powder, stable nature, good heat resistance, long-term preservation, the water solution is also true;

2, the agent strong penetration, strong emulsification, can fine-grained grease and dirt, and can make it out of the metal surface;

3, the agent is alkaline, non-corrosive to metal, easy to use cold water washing metal degreasing agent, electrolytic release agent. The working principle of the metal degreasing agent is as follows.

First, the electrostatic repulsion is the role of the copolymer dissolved in water after adsorption on the inorganic salt of the microcrystalline, so that the repulsion between the particles increased, hinder their coalescence, so that they are in a good dispersion, so as to prevent or reduce the formation of dirt.

Second, the network and the role of solubilization is dissolved in water after ionization, the formation of negatively charged molecular chain, it forms a water-soluble complex or chelate with Ca2 +, so that the solubility of inorganic salts increased To scale effect.

Third, the lattice distortion by the functional part of the molecule in the inorganic salt nuclei or microcrystalline, occupy a certain position, hinder and destroy the normal growth of inorganic salt crystals, slowing the growth rate of the crystal, thereby reducing the The formation of salt scale.

What should we pay attention to when we use a metal degreasing agent? Here for you to carefully introduce, look at the interest together to see it.

First, to prevent the use of metal degreasing agent degreased after the workpiece surface to produce dry film

The so-called dry film refers to the workpiece after degreasing, before and after washing to produce a dry film, the existence of such dry film will affect the integrity and uniformity of phosphating film, resulting in blue and yellow rust. It is necessary in the degreasing and washing interval, washing and dialing interval set micro-mist spray (when the process more than 1min, additional spray equipment), to prevent drying.

Second, improve the quality of washing

2, improve the quality of washing

The use of metal degreasing agent after degreasing washing is a very critical process, because the surface of the residual metal degreasing agent (containing SiO32-, Cl-, SO42-, CO32- and surfactants, etc.) to form a coating, affecting the phosphating effect (crystal The number of nuclear reduction, phosphating film thinning, and rough, resulting in white spots, filaments, flowers and other defects, corrosion resistance); coating produced shrinkage, pinholes and other defects). To this end, the following measures can be taken.
