DTPMPA (triformic acid diphosphate) is a commonly used chelating agent, mainly used in water treatment, industrial cooling water systems and other related applications. It is a complex of many components, the main components may include the following:

1. Triformic acid diphosphate (DTPMP) : DTPMP is the main component of DTPMPA and the source of its nomenclature. It is an organic phosphate, with good corrosion inhibition, scale inhibition and chelating metal ions.
2. Methanol: Methanol is commonly used as a solvent or diluent for dtmpa to adjust its concentration and performance.
3. Alkalinity: to adjust the pH of dtmpa and increase its solubility, small amounts of alkalinity, such as sodium hydroxide acid (NaOH) or potassium hydroxide acid (Koh) , may be added.
4. Other additives: depending on the specific requirements, may be added some auxiliary ingredients, such as buffer, stabilizer, co-solvent, etc. , to enhance the performance and stability of dtmpa.
   It is important to note that different manufacturers and products may use different formulations and composition combinations, there may be subtle differences. When using DTPMPA or any other chemical, read the product instructions carefully and follow the correct method of use and safe operating procedures to ensure safe use and desired results.

HPMA is an acronym for Water Treatment Agents Hydrolyzed Polymaleic Anhydride, the main use of this product is:

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.

HPMA is also widely used in desalination plant of flash vaporization equipment, steam locomotive and petroleum pipeline. In addition, It can be used in combination with phosphonates to improve performance and reduce phosphonate levels and thus provide a superior alternative to acrylate-based polymers. It can also be used as dispersant and scale inhibitor in cooling water treatment, Reverse Osmosis systems and many other scale control applications.

Properties:

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

PAAS 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, 2-15mg/L is preferred. When used as dispersant, the dosage should be determined by experiment.
