the main components of paint dispersants usually include organic solvents, Surfactant and stabilizers.

Organic solvents: common organic solvents including acetone, methanol, ethanol, butanol, etc. , used to paint pigments dissolved, so that it becomes easier to smear and uniform dispersion.

SURFACTANT: the Surfactant reduces the surface tension of the liquid, causing the pigment to disperse evenly and preventing the pigment from precipitating in the paint. Common Surfactant include sodium dodecyl benzene sulfonate, octyl phenol polyoxyethylene ether, etc. .

Stabilizer: stabilizer can prevent pigment in paint caking and precipitation, improve the stability of paint and shelf life. Common stabilizers include polyacrylate, polyvinyl alcohol, etc. .

In addition, paint dispersant ingredients may also include preservatives, antioxidants, etc. , to improve the paint antibacterial, antioxidant properties. Different types of paint dispersants may vary in composition, the specific composition of the product according to the formula to determine.

The dosage of Ro scale inhibitor will vary according to the specific situation, including the water quality of the water source, membrane materials used and equipment requirements. In general, the amount of anti-scaling agent should comply with the following principles:
according to water quality analysis: first, the need for water quality analysis, understanding the water hardness, salinity and other pollutants. These data can be used as the basis for determining the dosage of scale inhibitor.
Follow the manufacturer’s advice: according to the use of specific scale inhibitor products, refer to the manufacturer’s instructions and recommended dosage. These guidelines are generally based on experimental and empirical data, which can provide a better dosage of reference.
Consider membrane components: scale inhibitor dosage should also be based on the type of reverse osmosis membrane used and requirements for adjustment. Different types of membranes may have different adaptability to scale inhibitors, so they need to be added without damaging the membrane components.
System monitoring and adjustment: once adding scale inhibitor, the performance of the system and water quality should be monitored regularly, and necessary adjustment should be made according to the monitoring results. This can ensure that the amount of scale inhibitor can adapt to the actual operation of the system.
In a word, the dosage of Ro scale inhibitor should be determined according to the specific conditions. It is suggested that the dosage should be adjusted on the basis of consultation with the manufacturer, reference to the product specification and systematic monitoring. This can achieve a better scale inhibition effect and protect the performance of reverse osmosis equipment.

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.
