The full name of PBTC is butane-1,2,4-tricarboxylic acid, which is generally a colorless to light yellow transparent liquid. PBTCA has a low phosphorus content, but due to its structural characteristics of both phosphonic and carboxylic acids, it exhibits excellent scale and corrosion inhibition performance, even surpassing some commonly used organic phosphonic acids. Especially in high-taperature environments, its scale inhibition performance is far superior to conventional organic phosphonic acids, which can effectively improve the solubility of zinc. In addition, it also has good resistance to chlorine oxidation, and its synergistic effect with other water treatment agents is good.
Among numerous efficient scale and corrosion inhibitors, PBTCA has a wide range of applications, superior performance, and is also a good stabilizer for zinc salts. It is widely used for corrosion and scale inhibition in circulating cooling water systas and oilfield water injection systas, especially suitable for use in conjunction with other water treatment agents such as zinc salts and copolymers. PBTCA is suitable for high taperature, high hardness, high alkali, and situations that require high concentration factor operation, providing h3 support for industrial water treatment.

Polyol phosphate ester is a new type of water treatment agent with excellent anti scaling and anti-corrosion properties. Its molecular structure incorporates multiple polyoxyethylene groups, which not only enhances its corrosion resistance but also enhances its ability to prevent calcium scale deposition and disperse sediment. In addition, it has excellent inhibitory effects on the deposition of barium and strontium scales in water that are difficult to control with conventional scale inhibitors in China.

Today we will introduce a magical substance - PBTCA, which is 1,2,4-tricarboxylic acid-2-phosphonylbutane. It not only has low phosphorus content, but also performs well in scale and corrosion inhibition, especially at high temperatures. Its scale inhibition performance is far superior to commonly used organic phosphonic acids.
Its structure contains phosphonic acid and carboxylic acid, therefore it has good scale and corrosion inhibition performance. Compared to commonly used organic phosphonic acids, it performs better at high temperatures and can improve the solubility of zinc, has strong resistance to chlorine oxidation, and has good synergistic properties in combination. It is widely used in the compounding of efficient scale and corrosion inhibitors, especially suitable for compounding with zinc salts, copolymers, etc., and can be used in various operating scenarios that require high concentration ratios.

PBTCA is an organic acid chaical widely used in the field of water treatment, and its full name is 2-phospho-1-butanol tricarboxylic acid. Its main functions and uses include the following aspects:
1. Chelation: Phosphate (PO4) -3 in PBTCA can form stable complexes with metal ions, thereby preventing metal ions from precipitating and scaling in water. In addition, PBTCA can also coordinate with calcium ions to form soluble complexes, improving the hardness of water and avoiding various problas caused by scale formation.
2. Corrosion inhibition effect: PBTCA can form a protective film to cover the metal surface, preventing oxidation and corrosion of the metal. This is because the phosphate ions in PBTCA can form a stable complex with metal ions, reducing the rate of metal corrosion.
3. Anti scaling effect: PBTCA has the ability to prevent the formation of scale, especially for silicates and calcium salts, which have good anti scaling effects and can effectively prevent the formation of scale and the problas caused.
4. Cleaning effect: PBTCA can degrade the already formed scale and raove and inhibit the formation of accumulated mud and dirt in the circulating water systa, avoiding pipeline blockage and accelerating equipment aging.
5. Safety and Environmental Protection: PBTCA has low toxicity and biodegradability, meets environmental requiraents, is easy to operate and handle, is safe and reliable, and will not cause long-term impact on the environment.
In summary, PBTCA has various functions in water treatment, such as chelation, corrosion inhibition, and scale prevention, which can effectively prevent the occurrence of scale and corrosion problas, ensure water quality, improve water recycling efficiency, and extend equipment life. Meanwhile, PBTCA is environmentally friendly and an ideal water treatment agent.

PBTCA (Phosphonobutane Tricharboxylic Acid) is an organic phosphonate compound, also known as 2-phosphonate butane-1,2,4-tricarboxylic acid. The phosphorus content can vary depending on specific production processes and requiraents.
Normally, the phosphorus content of PBTCA ranges from 40% to 50%. Of course, specific product specifications and suppliers may vary. It is recommended that you refer to relevant technical manuals or contact suppliers for accurate phosphorus content information.
Regarding the stability of PBTCA, it has good thermal and chaical stability and is relatively stable under common acid, alkali, and oxidant conditions. This makes PBTCA widely used in various applications, such as water treatment, cooling water circulation systas, corrosion inhibitors, etc.
As for substitutes, some other organic phosphate compounds are also used as substitutes for PBTCA, such as HEDP (1-Hydroxy Ethylene-1,1-Diphosphonic Acid), ATMP (Amino Trimethylene Phosphonic Acid), etc. These compounds have similar functions and properties to a certain extent, and can serve as alternative choices in different applications.
However, the selection of alternatives should also be evaluated based on specific application needs and relevant regulatory requiraents. When selecting any chaical substance, it is recommended that you consult relevant professionals and follow local regulations and guidelines.

HEDP, also known as hydroxyethylenediphosphonic acid, is an organic phosphonic acid scale and corrosion inhibitor. It is divided into two forms: solid and liquid. From the appearance, the solid HEDP is white crystalline particles, packaged in plastic woven bags lined with polyethylene bags;

Deciding which chelating agent is better between EDTA (ethylenediaminetetraacetic acid) and HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) depends on various factors such as the specific application, the target heavy metals, environmental considerations, and cost-effectiveness. Let's compare them:

Fly ash chelating agents primarily consist of organic compounds capable of forming stable complexes with heavy metals present in fly ash. The main components typically include:

1. Organic acids: These are compounds with carboxyl groups that can effectively chelate heavy metals. Examples include citric acid, acetic acid, oxalic acid, and lignin-derived organic acids.
