Ceramics Industry
1. Improving the Dispersibility of Ceramic Slurry
• Sodium Tripolyphosphate (STPP) is an efficient dispersant that can prevent the aggregation of ceramic raw material particles (such as clay and feldspar) in the slurry, ensuring uniform dispersion of the particles.
• This uniform dispersion helps enhance the uniformity of the ceramic product's texture and surface smoothness.
2. Regulating the Viscosity of the Slurry
• In ceramic production, STPP can effectively control the viscosity of the ceramic slurry, making it more suitable for shaping and casting.
• By regulating the viscosity, STPP helps reduce defects in the production process and improve production efficiency.
Detergents
1. Enhancing Cleaning Performance
• Chelation: STPP can chelate metal ions in water, preventing these ions from combining with surfactants in the detergent, thereby enhancing the detergent's ability to remove dirt.
• Dispersing dirt: It has good dispersibility, which can break down dirt and grease into fine particles, preventing them from redepositing on the fabric surface. This dispersion helps to thoroughly remove stains and make clothes cleaner.
• Emulsifying grease: STPP can promote the emulsification of grease, making it easier to be rinsed away by water. This is particularly effective for removing stubborn oil and stains.
3. Improving Detergent Performance
• Preventing caking: During the production of detergents, STPP can prevent the granules of detergent from caking, maintaining the dry and granular form of the detergent.
• pH buffering: STPP has a strong alkaline buffering effect, which can maintain the pH value of the washing solution around 9.
4. This alkaline environment is conducive to removing acidic dirt.
Water Treatment
1. Water Softening
• Removal of hardness ions: Sodium tripolyphosphate can react with hardness ions such as calcium and magnesium in water to form soluble complexes, thereby reducing the hardness of water.
• Preventing scale formation: By chelating hardness ions, sodium tripolyphosphate can effectively prevent the deposition of scale on the surfaces of equipment such as pipes, boilers, and coolers, reducing equipment blockage and corrosion.
2. Corrosion Inhibition
• Formation of protective film: Sodium tripolyphosphate can form a protective corrosion-inhibiting film on the surface of metals, preventing contact between metals and corrosive substances in water, thereby reducing metal corrosion.
• Extending equipment life: This corrosion-inhibiting effect can significantly extend the service life of industrial equipment and reduce equipment maintenance costs.
Leather Industry
1. Pre-Tanning Treatment
• Improving leather quality: Sodium tripolyphosphate is commonly used as a pre-tanning agent in leather processing. It can combine with the collagen fibers in leather, enhancing the flexibility and elasticity of the fibers, thereby improving the overall quality of the leather.
• Removing fats and oils: In the early stages of leather processing, animal hides often contain a large amount of fats and oils on their surfaces. Sodium tripolyphosphate can chemically react with these fats and oils to form soluble complexes, effectively removing them. This step is crucial for the subsequent tanning process, as excessive fats and oils can affect the tanning effect and final quality of the leather.
