ActiveLimestone for chemical industry--Determination of insoluble matter content of hydrochloric acid--Gravimetric method
化工用石灰石中盐酸不溶物含量的测定 重量法
Application Summary AI generated
This standard specifies the gravimetric method for determining the content of hydrochloric acid-insoluble matter in limestone used as a raw material in the chemical industry. It is applied in quality control and testing laboratories to evaluate the purity and suitability of limestone for processes such as the production of calcium carbide, soda ash, and fertilizers. The method ensures that the limestone meets required chemical specifications by quantifying non-reactive residues after acid treatment.
