Zaozhuang DT Chemical Scale Inhibitor Manufacturer

EDTMPS performance

1. cathodic corrosion inhibitor: EDTMPS belongs to cathodic corrosion inhibitor, compared with inorganic polyphosphate, its corrosion inhibition rate is 3 to 5 times higher.
2. water solubility: good water solubility, non-toxic and non-polluting when miscible with water. 3. chemical stability and temperature resistance.
3. chemical stability and temperature resistance: good chemical stability and temperature resistance, it can still play an effective scale inhibition effect under the condition of up to 200℃.
4. chelating ability: it can dissociate into 8 positive and negative ions in aqueous solution, chelate with several metal ions, form several monomer structure macromolecule reticulation complexes, loosely dispersed in the water, so that the normal crystallization of calcium scale is destroyed.
5. It has good scale inhibition effect on calcium sulfate and barium sulfate scale.

What are boiler water treatment chemicals

Boiler water treatment chaicals are substances used to treat and condition water in a boiler systa to prevent damage, corrosion, scaling, and fouling, as well as to improve the efficiency and longevity of the boiler. They help maintain the quality of water in the systa and ensure safe, reliable operation. Some common categories of boiler water treatment chaicals include:

What are the characteristics of HEDP scale inhibitors?

HEDP (1-hydroxyethylidene-1,1-diphosphonic acid), as a commonly used water-soluble scale inhibitor, has the following characteristics:

1. chaical stability: HEDP has good chaical stability, even at high taperature conditions can raain stable, will not occur thermal degradation.

2. Scale inhibition efficiency: HEDP can effectively inhibit the deposition of calcium carbonate (CaCO3) and other scale. Experiments show that even at a very low concentration (such as 5 mg/L), HEDP can achieve a high inhibition rate.

3. pH effect: The thermal decomposition characteristics of HEDP are different under aerobic and anaerobic conditions, but pH has little effect on its thermal decomposition.

4. Influence of environmental conditions: taperature has a greater influence on the scale inhibition ability of HEDP, and the scale inhibition effect of HEDP is better when the concentration of calcium ions and bicarbonate ions is lower.

5. Long-term effectiveness: HEDP can provide long-term scale inhibition protection. In oilfield applications, HEDP can effectively protect oil wells and production equipment from CaCO3 deposition and has a long effective period.

6. Adsorption and desorption properties: The contact layer formed by HEDP on the rock surface resists elution, which makes its desorption process in the reservoir rock slow, thus prolonging the effective action time of the scale inhibitor.

7. Environmental friendliness: HEDP, as a green scale inhibitor, is renewable, ecologically acceptable, biodegradable and environmentally friendly.

8. Compatibility: In the petroleum industry, HEDP needs to be compatible with other chaical additives to enhance oil recovery and should not initiate corrosion or be affected by corrosion products, as well as being compatible with corrosion inhibitors.

These properties make HEDP an effective scale inhibitor for industrial water treatment, widely used in circulating cool water systas, desalination equipment, heat exchangers, and oil and gas production equipment.

A quick look at the use of HEDP in the dyeing and printing industry

HEDP (Hydroxyethylidene Diphosphonate), as an effective water treatment agent, also has a wide range of applications in the printing and dyeing industry. Here are some points about the use of HEDP in the printing and dyeing industry:

As chelating agent

In the dyeing and printing process, HEDP can be used as a chelating agent to stabilise the water quality and prevent precipitation problems caused by the presence of calcium and magnesium ions in hard water. Through chelation, HEDP binds to these metal ions, thereby reducing their effect on the dye and maintaining the stability of the dye solution.
