Spray Drying of Sodium phosphate / silicate mixture
Spray drying is a commonly used technique to produce dry powders from liquid mixtures, such as sodium phosphate/silicate, for improved handling, storage, and transport. The mixture of sodium phosphate and silicate is commonly used in various applications, including detergents, ceramics, and fire-resistant coatings.
The spray drying process involves atomizing a solution of the sodium phosphate/silicate mixture in a solvent into a fine mist, which is then rapidly dried in a stream of hot air. The resulting dry powder consists of small, spherical particles with controlled size and shape. The process allows for the production of a large quantity of uniform particles with excellent flowability and dispersion properties.
The properties of the sodium phosphate/silicate powders produced by spray drying can be tailored by adjusting the process parameters, such as the inlet temperature, feed rate, and drying time. The use of different solvents or drying aids can also affect the properties of the final powder.
Overall, spray drying is an effective method for producing sodium phosphate/silicate powders with controlled properties, which can improve the performance and efficacy of the final product. The process allows for the production of a large quantity of uniform particles with excellent flowability and dispersion properties, which can enhance the detergency, ceramic properties, and fire resistance of the mixture.
