Green scale inhibitors and dispersants are a class of chaicals that are of great significance in the field of water treatment. They can effectively prevent the formation of scale and have the characteristics of environmental protection and biodegradability. The following is an overview of the research progress on green scale inhibitors and dispersants:
1. Oilfield scale control: The issue of oilfield scale has always been one of the main issues in ensuring oilfield flow. Although traditional phosphorus containing scale inhibitors have significant effects, they have a negative impact on the environment due to their involvaent in eutrophication processes. Therefore, green scale inhibitors such as polyaspartic acid (PASP), polyepoxysuccinic acid (PESA), plant extracts and their derivatives have been developed to replace traditional products.
2. Application in the field of water treatment: In water treatment fields such as circulating cooling water systas, seawater desalination devices, and industrial water for secondary oil recovery, scaling problas seriously affect water use and treatment efficiency, and may even damage equipment and create safety hazards. Green scale inhibitors have gradually become a focus of research and development due to their environmental characteristics.
3. Enhancing environmental awareness: With the increase of environmental awareness, the use of phosphorus containing scale inhibitors is restricted, prompting researchers to develop non-toxic, efficient, and biodegradable green scale inhibitors. These new scale inhibitors not only effectively alleviate the scaling probla of circulating water, but also conform to the concept of green development.
4. New green scale inhibitors: In recent years, some new and efficient green scale inhibitors have been reported, such as polyaspartic acid, polyepoxysuccinic acid, and gamma polyglutamic acid. They have the characteristics of being non-toxic, efficient, and biodegradable, representing the development trend of research in the field of water treatment [^ 6 ^].
5. Application in oilfield development: In oilfield development, green scale inhibitors such as polyepoxysuccinic acid and polyaspartic acid are becoming the focus of research due to their environmental friendliness and high taperature resistance.
6. Research status and application progress: Green scale inhibitors have become the development direction of scale inhibitors in the 21st century due to their high scale inhibition performance, good biodegradability, and non toxicity. The research and application progress of the systa indicates that the types, properties, and application prospects of green scale inhibitors are broad.
These developments daonstrate the importance of green scale inhibitors in environmental protection and industrial applications, as well as their potential in future development. With the continuous progress of technology and the increasingly strict environmental regulations, the research and application of green scale inhibitors will continue to expand.pesa

If too much water-based dispersant is added, it may have the following effects on coatings or inks:

Stability Issues: An excess of dispersant can easily lead to a decrease in the stability of inks or coatings, making them prone to sedimentation and coagulation.

Shandong Kairui Chemistry Co., Ltd. is a company based in China that specializes in the production and export of various chemicals, including benzalkonium chloride (BKC) and dodecyl dimethyl benzyl ammonium chloride (DDBAC), which are commonly used as disinfectants and surfactants. If you're looking to import these chemicals, it's a good idea to reach out to them directly or through a trusted agent or importer/exporter platform to inquire about their products, pricing, and shipping options.

HEDP stands for 1-Hydroxyethylidene-1,1-Diphosphonic Acid. Its chemical structure is:

Here, it consists of a phosphonic acid group (─P(O)(OH)₂) with an additional hydroxyethyl (CH₂─OH) group attached to one of the phosphorus atoms.

The difference between HEDP solids and liquids is mainly reflected in their physical properties and uses. HEDP( 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid) has a colorless and transparent liquid state and a white crystal solid state. It has good chemical and thermal stability and is widely used as a chemical substance in industrial and agricultural fields.

Surfactants are not necessarily hazardous materials, but are determined by factors such as their specific type, concentration, use, and contact method. Some surfactants may pose certain hazards to human health or the environment, while others may be relatively safe.
Here are some considerations regarding the safety and potential hazards of surfactants:
Toxicity: Certain surfactants may have toxic effects on the human body at high concentrations, such as skin irritation, eye irritation, allergic reactions, etc. But when used at appropriate concentrations, most surfactants are relatively safe.
Biodegradability: Some surfactants may remain in the environment and have an impact on the ecosystem. Therefore, biodegradability is one of the important factors in evaluating the safety of surfactants.
Environmental impact: Certain surfactants may be toxic to aquatic organisms and may have negative impacts on aquatic ecosystems. Therefore, when selecting and using surfactants, attention should be paid to their impact on the environment.
Usage and concentration: The safety of surfactants depends on their usage and concentration. Reasonable use and strict adherence to the instructions can reduce potential hazards.
Individual differences: There are differences in the sensitivity of individuals to surfactants, and some people may have allergic reactions or other adverse reactions to certain surfactants.
Overall, surfactants themselves are not necessarily hazardous materials, but caution is needed in their selection, use, and handling to ensure compliance with relevant safety standards and regulations, and to minimize adverse effects on human health and the environment.

Surfactants play an important role in various applications, and their main functions include:
Reducing surface tension: Surfactants can reduce the surface tension of liquids, making it easier for liquids to wet solid surfaces. This characteristic gives it excellent penetration and cleaning performance in products such as cleaning agents and detergents.
Enhanced dispersion and emulsification: Surfactants can form micelles at the oil-water interface, dispersing oil droplets in water or oil, thereby enhancing the dispersion and emulsification between liquids, making them easier to mix and stabilize.
Wettability: Surfactants can reduce the contact angle between liquid and solid surfaces, making it easier for the liquid to unfold on the solid surface, thereby improving wettability and making the liquid cover the solid surface more evenly.
Foaming properties: Some surfactants have good foaming properties and can form stable bubbles in liquids, which are used in washing, cleaning, and personal care products.
Stabilizing lotion: surfactant can stabilize lotion, keep oil or water droplets dispersed, prevent precipitation or phase separation, thus extending the stability and shelf life of the product.
Thickening and viscosity adjustment: some surfactants can form gel structure in aqueous solution, thus increasing the viscosity and consistency of liquid, which is used to adjust the texture and fluidity of products.
Antistatic effect: Surfactants can form a protective film on the surface of objects, reduce the generation and accumulation of static electricity, and prevent the occurrence of static electricity.
In general, surfactants have many functions, such as wetting, cleaning, dispersion emulsification, stabilizing lotion, thickening viscosity, etc., and are widely used in detergent, detergent, personal care products, industrial products, pharmaceutical products and other fields.
