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.



In the washing industry, PBTC can be used as a chelating agent and metal cleaning agent. To achieve optimal results, it is usually compounded with other water treatment agents such as zinc salts, copolymers, organic phosphorus, azoles, etc. When used alone, the dosage is usually 5-15mg/L.
In terms of packaging, PBTCA uses plastic drums with a capacity of 25Kg or 250Kg per drum. It should be stored indoors in a cool and shady place for a storage period of twelve months. However, it should be noted that PBTCA is an acidic substance, and labor protection should be strengthened during operation to avoid contact with skin, eyes, and other parts. If contact occurs accidentally, rinse immediately with plenty of water.

Polyacrylic Acid (PAA) plays a crucial role in water treatment due to its unique chemical properties. Here’s how PAA works in water treatment:
1. Flocculation

• Mechanism: PAA acts as a flocculant by binding to suspended particles in the water. These particles are typically negatively charged, and PAA, being a polyelectrolyte, can neutralize these charges.
  
• Process:
  
  • Charge Neutralization: PAA molecules carry positive charges (due to the ionization of carboxylic acid groups) that can neutralize the negative charges on suspended particles.
    
  • Bridge Formation: Once the charges are neutralized, PAA molecules can form bridges between the particles, causing them to aggregate into larger flocs.
    
  • Settling: The larger flocs are more likely to settle to the bottom of the water due to gravity, making it easier to remove them through sedimentation or filtration.
    

2. Scale Inhibition

• Mechanism: PAA can prevent the formation of scale (such as calcium carbonate) by chelating metal ions in the water.
  
• Process:
  
  • Chelation: The carboxylic acid groups in PAA can form complexes with metal ions like calcium (Ca²⁺) and magnesium (Mg²⁺), which are common components of scale.
    
  • Disruption of Crystal Growth: By chelating these ions, PAA disrupts the nucleation and growth of scale crystals, preventing them from forming a solid deposit on surfaces.
    

3. Corrosion Inhibition

• Mechanism: PAA can form a protective film on metal surfaces, reducing the rate of corrosion.
  
• Process:
  
  • Adsorption: PAA molecules adsorb onto metal surfaces due to electrostatic interactions and van der Waals forces.
    
  • Barrier Formation: The adsorbed layer of PAA acts as a barrier, preventing corrosive agents (such as dissolved oxygen and chloride ions) from coming into contact with the metal surface.
    
  • Passivation: This protective film can also passivate the metal surface, reducing the electrochemical reactions that lead to corrosion.
    

4. pH Buffering

• Mechanism: PAA can act as a pH buffer, helping to maintain a stable pH in the water.
  
• Process:
  
  • Ionization: The carboxylic acid groups in PAA can ionize, releasing hydrogen ions (H⁺) or accepting them, depending on the pH of the water.
    
  • pH Stabilization: This ionization process helps to resist changes in pH, which is important for maintaining the effectiveness of other water treatment processes.
    

5. Viscosity Modification

• Mechanism: PAA can increase the viscosity of water, which can be beneficial in certain water treatment processes.
  
• Process:
  
  • Polymer Chain Expansion: In solution, PAA molecules expand and entangle, increasing the viscosity of the water.
    
  • Enhanced Particle Removal: The increased viscosity can help to keep flocs suspended in the water, making it easier to remove them through processes like dissolved air flotation (DAF).
    

SummaryPolyacrylic Acid (PAA) is a versatile polymer that plays multiple roles in water treatment:

• Flocculation: Neutralizes charges and forms bridges to aggregate particles.
  
• Scale Inhibition: Chelates metal ions to prevent scale formation.
  
• Corrosion Inhibition: Forms a protective film on metal surfaces.
  
• pH Buffering: Maintains a stable pH in the water.
  
• Viscosity Modification: Increases water viscosity to enhance particle removal.
  

These properties make PAA an essential component in various water treatment processes, ensuring the efficient removal of impurities and the protection of equipment.

​Sodium polyacrylate dispersant is an important polymer compound with a wide range of uses:
I. Uses in the field of coatings and paints
Pigment dispersion - Polyacrylic Acid Sodium Salt Solid can be adsorbed on the surface of pigment particles. Due to its molecular chain with a large number of carboxyl and other polar groups, these groups can prevent the pigment particles from agglomerating in the coating system through electrostatic repulsion and spatial site resistance effect. For example, in water-based coatings, the dispersion effect is very good for inorganic pigments such as titanium dioxide. When the pigment particles are evenly dispersed, the color of the paint is more uniform and the covering power can be effectively improved. - It also improves the fluidity of the pigment, which makes the paint easier to brush or spray during the construction process and reduces the probability of defects such as sagging and orange peel. 2.
Improve paint stability - Sodium polyacrylate dispersant helps to maintain the stability of the coating system during the storage of the coating. It prevents pigment settling and ensures that no pigment delamination occurs when the paint is left for a long period of time. This is very important for prolonging the shelf life of the paint, especially for some industrial and architectural paints that need to be stored for a long time.
Second, the use in the ceramic industry
Dispersion of ceramic blanks and glazes - In the preparation of ceramic blanks, it can disperse various mineral particles in ceramic raw materials, such as quartz, feldspar and so on. These mineral particles can be mixed more evenly under the action of the dispersant, which is conducive to the molding of the blank. In glaze, sodium polyacrylate dispersant can make the color and other additives in the glaze evenly dispersed, thus improving the quality of the glaze and making the glaze of ceramic products smoother and more uniform in color. 2.
Prevent agglomeration and precipitation - Ceramic slurry in the preparation a
