Applications
Amino Trimethylene Phosphonic Acid is used as chelating agent and its threshold prohibition value is low .this chemical is known by its antiscaling properties calcium carbonate is the main chemical that this compound is prevent to creat scale on equipments in water and cooling systems. In addition to all above properties of ATMP it has great corrosion inhibitir property in higher concentrations. Industrially , it can be use in water systems like cooling water systems and thermal power plants . because equipments like popes and towers are made of metal adding Amino Trimethylene Phosphonic Acid can decrease scale formation and also it acts as a corrosion inhibitor. In other industrial fields like dye and paint it can be added as a chelation factor.
As a matter of fact in order to prolong equipments longevity it is better not to let scales to formn and in this case one of the chemicals that is very effective is ATMP due to its thermal stability and good chelation properties . by the formation of soluble complexes with metal ions like calcium, aluminium, zinc, iron and magnesium. Fouling of the boilers may cuase several problems to water systems and because the water need to use in boilers must be high quality by the terms of suspended solids and particles so using this chemical in waters as a scale inhibitor has so many advantegous . by the chelation of atmp and salts like carbonate it keeps the in solution and prevent the scale and foulings occure. By using scale inhibitors like atmp the efficiency of equipments like bopilers increase . and because changing equipments in industry cost a fortune so using scal inhibitors like mentioned product seem reasonable. In chillation and cooling water systems corrosion may cuase during a period of time so this antiscale chemical can prevent this phenomena.
