The index of moisture content is one of the important indexes in the detection index of brucite products, which directly affects the application of downstream customers. If the moisture content of the flame-retardant chemical brucite product is high, adding it to the flame-retardant products may affect the application performance of the products, and foaming and steam overflow will occur during the processing of the products, resulting in appearance or internal defects of the flame-retardant products, which will affect their application performance.
