Water treatment agent

Amino tris(methylene phosphonic acid), its solid form is crystalline powder, soluble in water, hygroscopic, has excellent chelation, low threshold inhibition and lattice distortion. It has excellent scale inhibition below 200 ℃, low toxicity, good thermal stability, Amino tris(methylene phosphonic acid) can be dissociated into six positive and negative ions in the water, and can form a stable chelate with a variety of metal ions such as iron, copper, aluminum, zinc, calcium, magnesium, etc. It has a more preferable scale inhibition effect on carbonate . And it has good synergy with the polyphosphate, polycarboxylate, nitrite. There are good inhibition when in 40mg/L.

Instructions

Amino tris(methylene phosphonic acid) is often used with other organic acid, polylactic acid or salt to form organic water treatment agents for circulating cooling water systems under a variety of different water quality conditions. The amount of 1~20mg/L is preferred; in an amount of 20~60mg/L when used as a corrosion inhibitor . Amino tris(methylene phosphonic acid)is acidic, pay attention to labor protection, should avoid contact with eye and skin, once contacted, flush with plenty of water.

Usage

Used for the scale prevention of cooling water system, oil pipeline and boiler; Used as the scale inhibitor for the oil pipeline with high hardness, high salinity and bad water quality; Used as scale inhibitor and corrosion inhibitor for the treatment of cooling water, boiler water, oil field water; Used for circulating cooling water of thermal power plant and an oil refinery.

General Description

Nitrilotris(methylene)triphosphonic acid solution is an antiscalant and can be removed form membrane concentrates by iron-coated waste filtration sand. It is a cement retarder. It reacts with the aluminum surface to form a coating which is an effective inhibitor of the reaction of evaporated aluminum thin films on glass or silicon with deionized water.
