| Water treatment agent | amino trimethylene phosphonic acid (aminotrimethylene phosphonic acid) solid is crystalline powder, soluble in water, easy to absorb moisture, it has good chelation, low limit inhibition and lattice distortion. It has excellent scale inhibition effect below 200 ℃, low toxicity, good thermal stability, can dissociate into six positive and negative ions in water, and can be applied to iron, copper, aluminum, zinc, calcium, magnesium and other metal ions chelate to form a stable complex, especially for carbonate scale. And with polyphosphate, polycarboxylate, nitrite has good synergistic ability. There is a good corrosion inhibition in 40mg/L. aminotrimethylenephosphonic acid (ATMP) is a methylene phosphonic acid type compound, which is one of the agents used earlier in water treatment agents. Because it can form double five-membered ring chelate with Ca2 ,Mg2 ,Zn2 ,Fe2 and other metal ions in water, it has good effect of inhibiting calcium carbonate scale and corrosion inhibition performance on carbon steel. ATMP is an organic phosphorus acid scale inhibitor, which is not easy to hydrolyze and has a temperature resistance of more than 100°C. Dosage is relatively low, has better anti-scaling effect. |
| способ использования | amino trimethylene phosphonic acid ATM is often combined with other organic phosphoric acid, polycarboxylic acid or salt into organic alkaline water treatment agent, for a variety of different water quality under the circulating cooling water system. The dosage of 1~20mg/L is better, when used as corrosion inhibitor, the dosage is 20~60mg/L. Amino trimethylene phosphonic acid is stored in a cool and ventilated place indoors, moisture-proof and protected from sun exposure. amino trimethylene phosphonic acid is often combined with other organic phosphonic acids, polycarboxylic acids or salts to form organic water treatment agents, which are used in circulating cooling water systems under different water quality conditions. The dosage of 1~20mg/L is better; When used as corrosion inhibitor, the dosage is 20~60mg/L. Amino trimethylene phosphonic acid is acidic, attention should be paid to labor protection during operation, should avoid contact with skin, eyes and so on, and should be washed with plenty of water immediately after contact. |
