This series of products is made up of all kinds of organic compounds, such as multi - copolymer, organic phosphonic acid, copper corrosion inhibitor and so on. You can at a low concentration on the dispersion and fouling ion chelating and lattice distortion and so on, to prevent the deposition in the condenser fouling ion, to reduce the temperature difference, improve the vacuum degree, increase the unit output has significant effect. For carbon steel, stainless steel, copper, copper alloy has good corrosion inhibition effect.
