The chelation of scale inhibitors may be less known, although 　　Speaking of scale inhibitors, I believe that everyone is no stranger. Today, Xiaobian will tell you about the chelation of level inhibitors.

　　The process of an intricate having a cyclic composition wherein a main ion and two or more coordinating atoms of the identical polydentate ligand of specific circumstances are bonded is referred to as chelation. The consequence of the hydrazine collaboration is the range-developing cations (for example ca2 , Mg2 , and Sequestering agents many others.) react with the chelating professional to make a secure chelate, thereby avoiding it from forming a range anion (like co32-, Po4, one, 5042 and 51032, etc.

　　The make contact with helps make the probability of size creation greatly reduced. Chelation is carried out stoichiometrically, such as 1 EDTA molecule mixing a single divalent steel ion. The power from the chelating agent to bind might be depicted through the calcium supplements chelation value. The chelating potential in the professional water treatment method representative (this is 50Per cent in the lively part of each representative, and also the chelating capability is calculated by CaCO3): aminotrimethylene linonic acid (ATMP) - 300 milligrams / g: diethylene triamine Pentamethyl lincosic acid (DTPMP) - 450 mg / g: ethylenediaminetetraacetic acidity (EDTA) - 15om yrs old g: expanded by phenylethyl bis-linic acid solution (HEDP) - 45om.

　　In comparison, 1 milligrams of chelating representative are only able to chelate under .5 mg of CaCO3. The required chelating agent is l000 m Guo L, which is economically unacceptable, if the magnesium and calcium ions with a total hardness of smm0FL are to be stabilized in the circulating water system. It can be observed the participation of size inhibitor chelation is only a small part of it. In medium and low hardness water, it is still the sequestration of scale inhibitors.
