PHOSPHOMAN®-230

Polyamino Polyether Methylene Phosphonic Acid – PAPEMP

POLYAMINO POLYETHER METHYLENE PHOSPHONIC ACID

PHOSPHOMAN-230 Polyamino Polyether Methylene Phosphonic Acid is an organo-phosphonic acid offering multiple properties like sequestration, deflocculation, threshold inhibition and hydrolytic stability as well as scale & corrosion inhibition. The product is useful for dispersant of calcium, magnesium, Strontium, Barium, Silicates under savior plant conditions.

PAPEMP has excellent scale inhibition ability to calcium carbonate, calcium sulphate and calcium phosphate.

PAPEMP can efficiently inhibit the formation of silica scale, stabilize metal ions such as Zn, Mn and Fe. It effectively chelates metal ions including calcium, magnesium, iron and copper.

MAJOR PROPERTIES: –

Scale Inhibition

“Threshold effect” is the ability of very small amounts of scale inhibitors to keep large quantities of scale forming minerals in soluble form. PHOSPHOMAN-230 (PAPEMPA / PAPEMP) are highly effective scale inhibitors working on threshold limit. This is due to PHOSPHOMAN-230 (PAPEMPA / PAPEMP) being adsorbed on the growth site of the scale forming minerals like Calcium, Magnesium, Strontium, Barium, and Silica etc. altering the growth pattern of the scale, reducing the speed of growth and distorting the crystals. The threshold inhibition effectiveness of PHOSPHOMAN-230 (PAPEMPA / PAPEMP) depends on conditions such as the type of scale forming mineral, water composition, super saturations, temperature, pH and the type of PHOSPHOMAN-230 (PAPEMPA / PAPEMP) itself. PHOSPHOMAN-230 (PAPEMPA / PAPEMP) can be used as scale inhibitor for reverse osmosis system and multistep flash vaporization system in which high salt concentration, high turbidity and high temperature are usually encountered (such as high temperature and high turbidity in coal vaporization system), accessory agent for woven & dyeing (for example, yellow turn-back inhibition agent), as alternatives of EDTA, DTPA and NTA.

Sequestration

Sequestration (or chelating) is the ability of the substance to form a stable water-soluble complex with metal ions. The sequestration efficiency depends mainly on pH and the presence of other ions. The best comparison, however, can be made by the customer under actual use conditions.

Dispersion

Deflocculating or dispersion is the phenomenon that makes the agglomeration of growing crystals and other particulates more difficult. PHOSPHOMAN-230 (PAPEMPA / PAPEMP) have this property and also have the added attribute of maintaining such systems in a dispersed state over extended periods due to superior hydrolytic stability.

Corrosion Control

Corrosion occurs when metal is attacked by oxygen in water. PHOSPHOMAN-230 (PAPEMPA / PAPEMP) in combination with zinc or phosphates and other corrosion inhibitors are highly effective in inhibiting corrosion. The effect of these combinations is much greater than the effect of any component by itself.

Hydrolytic Stability

PHOSPHOMAN-230 (PAPEMPA / PAPEMP) is highly resistant to hydrolysis over a broad range of pH and temperature. This is very important for liquid formulations or where the process liquid is at elevated temperatures.

Chlorine Stability

Chlorine is a common oxidizer and biocide widely used in a variety of applications. Because PHOSPHOMAN-230 (PAPEMPA / PAPEMP) are stabilized with additives against chlorine (halogen) attack they perform maximum chlorine stability.
