PH Value 9.0-10.0 Stpp Sodium Tripolyphosphate White Granular Or Powder Used In Detergent Formulations And Water Treatment
Product Description:
Sodium Tripolyphosphate (STPP), also referred to as pentasodium triphosphate or simply sodium triphosphate, is a chemical compound with the formula Na 5 P 3 O 10 . It has a molecular weight of 367.86 and typically appears as white granules or powder. The apparent density of STPP ranges from 0.35 to 0.95 grams per cubic centimeter, and it has a melting point of 622°C.
This compound is highly soluble in water, where it produces an alkaline solution. Over time, STPP undergoes hydrolysis in aqueous solutions, gradually breaking down into orthophosphates. Due to its chemical nature, STPP has a remarkable ability to chelate metal ions, creating soluble complexes with ions such as calcium, magnesium, and iron. This chelating capacity effectively softens hard water.
Furthermore, STPP functions as an inorganic surfactant, displaying some properties that are similar to those found in organic surfactants. This makes it useful in various industrial and cleaning applications where such characteristics are desirable.
Features:
This process effectively chelates hardness ions present in water, such as calcium (Ca²⁺) and magnesium (Mg²⁺). By doing so, it significantly reduces the water hardness, which helps in minimizing the risk of inorganic salt deposition and scaling issues.
The substance acts to disperse and suspend solid particles as well as liquid droplets, thereby enhancing the stability and uniformity of various systems. In formulations related to ceramics and building materials, it is widely used as a water reducer, degummer, and dispersant. Its primary function is to stabilize body slurries and glaze slurries, making them easier to flow and shape. This results in improved process consistency and higher product quality.
It facilitates the emulsification and peptization of oily and protein-based soils. This property improves the detergency and overall cleaning efficiency, making it valuable in cleaning formulations.
By maintaining a weakly alkaline environment within the formulation, it aids in the effective removal of acidic soils. Additionally, this pH buffering contributes to the stabilization of the formulation’s overall performance.
