La polvere di guscio è una polvere ricavata dal guscio dopo la frantumazione, screening e altri processi. Its main component is calcium carbonate, but also contains a small amount of minerals and trace elements. Shell powder is widely used in construction, cosmetici, food and other fields, with good moisture absorption, heat preservation, purification, beauty and other properties.

Prestazioni di rilevamento
The performance testing of shell powder needs to consider several factors to ensure its quality and use effect. The following is a detailed description of the performance parameters to be detected for shell powder, come mostrato nella tabella seguente:

Metodo di rilevamento
The following is a detailed description of the test method for the performance parameters to be tested for shell powder:

Distribuzione delle dimensioni delle particelle: The particle size distribution of shell powder was measured using a laser particle size meter to evaluate its particle size and distribution uniformity.

Una specifica area di superficie: The specific surface area of shell powder was measured using a specific surface area analyzer to evaluate its surface area size and adsorption performance.

Composizione chimica: Chemical analysis was used to detect the chemical composition of shell powder to determine the content of main components, minerals and trace elements.

Hygroscopeability: The shell powder was placed in different relative humidity environments and its hygroscopeability was measured using the ambient humidity balance test.

Burning residue: Using a burning test, shell powder is heated to high temperature to measure the quality and content of its burning residue.

Clarity: Use visual inspection, microscope and other detection methods to detect the appearance, purezza, impurities of shell powder.

Glossiness: The glossiness of shell powder was measured using a glossometer to evaluate its surface gloss effect and glossiness stability.

Differenza di colore: The color difference of shell powder was measured using a color comparator to evaluate its color consistency and accuracy.

pH: The pH of shell powder was measured using a pH meter to assess its acidity, alkalinity and stability.

We reminds you that different performance parameters may require different test methods and equipment, and there may be some industry standards and specifications. For the performance test of shell powder, the corresponding test methods and standards should be selected according to the actual needs.
