HEDP·Na2 is an organic phosphonic acid scale and corrosion inhibitor that can form stable complexes with various metal ions such as iron, copper, and zinc, and can dissolve oxides on metal surfaces. It can still exhibit good corrosion and scale inhibition at 250℃, remains stable at high pH values, and is not prone to decomposition under general photothermal conditions. Its acid and alkali resistance, as well as its resistance to chlorine oxidation, are superior to those of other organic phosphonic acids (salts). HEDP·Na2 can form hexacyclic chelates with metal ions in water, especially calcium ions, thus exhibiting good scale inhibition and significant solubility limiting effects. When used in combination with other water treatment agents, it demonstrates an ideal synergistic effect.

HEDP?Na4 is weakly acidic, so it should be avoided from contacting eyes, skin, etc. If it is splashed on the body, it should be rinsed immediately with plenty of water.
HEDP?Na4 liquid is packaged in plastic drums, with each drum weighing 30Kg or 250Kg, which can be determined according to user requirements. The storage period is twelve months.
Oil-based amine ethyl imidazoline has good thermal stability, is non-toxic and has no irritating odor, posing no harm to the human body or the surrounding environment. It is an environmentally friendly corrosion inhibitor. The corrosion inhibition mechanism of oleylaminoethyl imidazoline is as follows: multiple polar adsorption centers and large-coverage non-polar groups are introduced into the molecule. By exerting a covering effect and increasing the activation energy of corrosion reactions, it prevents the corrosion of metal equipment by oxygen and carbon dioxide. It exhibits excellent inhibition effects against the corrosion caused by HCl, H2S, and CO2. In acid pickling media, after neutralization and salt formation, it can exist stably, reducing the surface tension of acidic aqueous solutions and imparting good wettability to the acid pickling solution. Over time, the product may sometimes crystallize, which is a normal phenomenon. It can still be used normally after being heated and melted. This product is soluble in low-carbon alcohols (ethanol, methanol, etc.), chlorinated hydrocarbons, toluene, mineral oil, etc., but not completely soluble in water. However, it can be dispersed in water. Due to its tendency to hydrolyze in its free state, it should be directly added to the acid pickling solution when used as an acid pickling inhibitor. After being quaternized, this product can be used as a cationic softener or antistatic agent, and also as an asphalt emulsifier.
