Pó de casca é um pó feito de casca após esmagamento, triagem e outros processos. Its main component is calcium carbonate, but also contains a small amount of minerals and trace elements. Shell powder is widely used in construction, cosméticos, alimentos e outros campos, with good moisture absorption, heat preservation, purification, beauty and other properties.

Desempenho de detecção

Método de detecção
The following is a detailed description of the test method for the performance parameters to be tested for shell powder:

Distribuição de tamanho de partícula: The particle size distribution of shell powder was measured using a laser particle size meter to evaluate its particle size and distribution uniformity.

Área específica da superfície: The specific surface area of shell powder was measured using a specific surface area analyzer to evaluate its surface area size and adsorption performance.

Composição química: 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.

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