TETHMP has strong properties of scale and corrosion inhibition and high thermal stability, which decomposition temperature of dry product is 223 ~ 245 ℃. It is easy to be degraded and safe to use. TETHMP can be used as scale inhibitor , efficient chelating agents, excellent barium sulfate scale inhibitor , which is widely used in cooling water treatment, peroxide bleaching stabilizer, detergent additives , municipal industrial clean water , geothermal water treatment and oilfield scale inhibitor.

TETHMP is a strong complexing agent with high dissociation degree in water, and can form a stable complex with Ca2+、Mg2+ and other metal ions. It can dissociate into twelve pairs of positive and negative ions in aqueous solution, chelate with two or more metal ions to form two or more complex of stereo macromolecule structure, loosely dispersed in water to destruct the normal crystalline of scale and prevent scale formation. It can effectively control the precipitation of carbonates, sulfates, phosphates, hydroxyl phosphates and ferric hydroxide and prevent the hard scale formation. In addition, TETHMP can form stable adduct with active oxygen compound (e.g.H2O2, etc.) to keep stability of active oxygen. As water quality stabilizer, it can be used to prevent scale in industrial circulating cooling water, dyeing water, low-pressure boiler feed water. It also used as precious metal extraction agent, metal ions equispaced agent in electroplating industry, scale inhibitor of metal surface phosphate treatment system, cleaning agent of metal surface.

HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cool water system, oilfield fill water, crude oil dewatering and low-pressure boilers. HPMA has good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.

PAA can be used as scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems. Dosage should be in accordance with water quality and equipment materials. When used alone, 1-15mg/L is preferred.

PAA is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. PAA can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAA is used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

EDTMPA can often be used in combination with other chaicals, but it depends on the specific chaicals and the intended application. Here are some common combinations and considerations:

Combinations with Other Water Treatment Agents

• Scale Inhibitors: EDTMPA is often used in combination with other scale inhibitors like polyacrylates or phosphonates. The different inhibitors can work synergistically to provide better scale control over a wider range of conditions. For example, EDTMPA is effective at chelating metal ions, while polyacrylates can prevent the aggregation of scale - forming particles.
• Corrosion Inhibitors: It can be combined with corrosion inhibitors such as zinc salts or benzotriazole. EDTMPA helps prevent scale formation, which can otherwise lead to under - deposit corrosion, while the other corrosion inhibitors protect the metal surfaces directly. The combination can provide comprehensive protection against both scale - related and general corrosion in water treatment systas.
• Biocides: In some water treatment applications, EDTMPA may be used with biocides like chlorine - based compounds or quaternary ammonium salts. The biocides control the growth of microorganisms in the water, and EDTMPA helps maintain the integrity of the water systa by preventing scale and corrosion, which could otherwise provide a habitat for microbes. However, care must be taken as some chaicals may react with the biocide and reduce its effectiveness. For example, high levels of EDTMPA might complex with metal ions that are necessary for the biocide to function properly.

Combinations in Other Industries

• Detergent Industry: In detergents, EDTMPA can be combined with surfactants, enzymes, and builders. The EDTMPA chelates metal ions in hard water, improving the performance of the surfactants by preventing the formation of insoluble metal - surfactant complexes. Builders like sodium carbonate or sodium tripolyphosphate can also be added to enhance the cleaning power, and enzymes can be included to break down specific types of stains. The combination of these components results in a more effective detergent formulation.
• Textile Industry: In textile dyeing, EDTMPA may be used with dyes, leveling agents, and fixing agents. It helps in chelating metal ions that could interfere with the dyeing process, ensuring more uniform and vibrant colors. Leveling agents help distribute the dye evenly on the fabric, and fixing agents improve the color fastness. However, it's important to ensure that EDTMPA does not react with the dyes or other agents in a way that would affect the final color or fabric quality.

When considering the combination of EDTMPA with other chaicals, it's essential to conduct compatibility tests and consult the relevant technical literature or experts. Factors such as pH, taperature, and the concentration of each chaical can influence their interactions and the overall effectiveness and safety of the combination.
