Polyamino Polyether Methylene Phosphonic Acid (PAPEMP) is a highly effective organophosphonic acid water treatment agent.PAPEMP has excellent scale inhibition, dispersion, and corrosion inhibition properties, and is particularly suited for high hardness and high alkalinity water conditions. Below is some key information about PAPEMP:
Chemical name: Polyamino polyether methyl phosphonic acid
CAS Number: The specific CAS number may vary from supplier to supplier, but is usually a unique identifier.
Molecular Formula: The molecular formula of PAPEMP may vary depending on the specific degree of polymerisation, but is generally expressed as CnH2n+1N(C2H4O)2PO3H2.
Molecular weight: The molecular weight will vary depending on the degree of polymerisation.
The molecular structure of PAPEMP contains several amino (-NH2), ether (-O-) and phosphonic acid groups (-PO3H2). This structure gives PAPEMP strong chelating ability and dispersing properties.
Appearance: PAPEMP is usually a colourless to light yellow transparent liquid.
Solubility: Soluble in water, the solution formed after dissolution is acidic.
pH value: the pH value of 1% aqueous solution is usually below 2.0.
Density: usually around 1.10 g/cm³ (20℃).
Scale inhibition performance: PAPEMP can effectively chelate calcium, magnesium and other hardness ions to prevent them from forming scale, especially for calcium carbonate scale has a very good inhibition effect.
Dispersing performance: PAPEMP can disperse the suspended particles in the water, prevent them from gathering to form deposits and keep the water system clean.
Corrosion inhibition performance: PAPEMP can provide some corrosion protection, especially in formulations containing zinc salts, which can enhance the corrosion inhibition effect of zinc salts.
Thermal stability: PAPEMP maintains good performance at high temperatures and is suitable for high temperature water treatment systems.
Environmentally friendly: Compared with some traditional water treatment agents, PAPEMP has better biodegradability and less impact on the environment.
Circulating cooling water system: PAPEMP is widely used in various industrial circulating cooling water systems, such as electric power, chemical industry, metallurgy and other industries to prevent scale and corrosion.
Boiler water treatment: It is used in boiler water treatment to prevent scaling inside the boiler and improve thermal efficiency.
Oilfield water injection: In oilfield development, PAPEMP can be used to prevent scaling of water injection pipelines and wellbores, and improve the efficiency of oilfield water injection.
Reverse osmosis system: as a pretreatment agent for reverse osmosis membrane, PAPEMP can reduce the scaling on the membrane surface and extend the service life of the membrane.
Textile Printing and Dyeing: PAPEMP can also be used as a chelating agent in textile printing and dyeing process, preventing dyes from combining with metal ions to cause colour change.
Concentration: The specific concentration of PAPEMP to be used needs to be determined according to the actual water quality conditions and treatment objectives. Usually the recommended concentration range is 5~20 mg/L.
Compounding: PAPEMP is often compounded with other water treatment chemicals (e.g. organophosphonic acids, polycarboxylic acids, zinc salts, etc.) to achieve a better overall effect.
pH: PAPEMP is suitable for water treatment systems with pH 7.0~9.5, but the optimum working pH range may need to be adjusted according to specific conditions.
Packing: PAPEMP is usually packed in 25kg or 250kg plastic drums.
Storage: It should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight and high temperature. Storage temperature should not exceed 40°C. Keep sealed to prevent moisture absorption.
Personal Protection: Personal protective equipment such as protective glasses and gloves should be worn during operation.
Emergency treatment: In case of inadvertent contact with skin or eyes, flush immediately with plenty of water and seek medical attention.
Waste Disposal: Waste should be disposed of in accordance with local environmental regulations and should not be discharged at will.
PAPEMP performs well in a variety of industrial water treatment applications due to its efficient scale inhibition, dispersion and corrosion inhibition properties. It should be used in strict accordance with the guidelines and Safety Data Sheets (SDS) provided by the manufacturer to ensure safety and effectiveness.
