The density measurement of refractories is one of the important methods to check the quality of refractories, which can evaluate the physical and chemical properties of refractories. The following are common refractory density detection methods:
1. Direct weighing method: Put the sample to be measured into the balance and calculate its density by weight. This method requires attention to the regularity of sample preparation and the accuracy of the balance.
2. Water drainage method: Put the sample to be tested into water and calculate its volume through displacement measurement. The density is then calculated using the direct weighing method. This method is suitable for materials with higher density.
3. Uniform suspension method: The sample to be tested is uniformly suspended in a certain depth of liquid, and its density is calculated by density comparison method. This method is suitable for materials whose density is less than that of suspension.
4, solvent replacement method: Through the solvent separation method to test the sample and the solvent interaction, so that the internal space of the sample is filled with solvent, and then through the direct weighing method to calculate the density. This method is suitable for materials with low porosity.
In short, in the detection of refractory density, it is necessary to choose the appropriate detection method, and pay attention to the influence of sample preparation, instrument accuracy and measurement environment and other factors to ensure the accuracy and reliability of the test results.
