| titleOfInvention | Method for measuring iron impurities in interior and exterior wall putty for building and heavy calcium carbonate |
| abstract | The invention relates to a method for measuring iron impurities in interior and exterior wall putty for buildings and heavy calcium carbonate. Specifically, the invention discloses a detection reagent, wherein the detection reagent comprises a copper salt, an acid and an optional first solvent, wherein the molar concentration of the copper salt is 0.5-2 mol/L and the molar concentration of the acid is 11-13 mol/L based on the total amount of the detection reagent. The detection reagent has the characteristics of simple composition and easiness in preparation and storage. The invention also discloses a method for detecting iron impurities by using the detection reagent, and the detection method has the characteristics of simplicity, rapidness, high efficiency, low cost and the like. Before leaving the factory, the putty is detected by adopting the detection method, so that the quality stability of the putty can be effectively improved, and the convenience of subsequent painting is enhanced. |
