About BULK DENSITY APPARATUS - MERCURY METHOD
-
INTRODUCTION:
- This technology was developed by the technical ceramics department of the University of Valencia and by the Research Association of the Ceramic Industry in Castellon, Spain.
- It is a better alternative for the measuring system for the strength of unfired ceramic material by means of penetration equipment, as the indicated values are not subjective and cannot be influenced by the operator: they are real values as they are based on the measuring of the apparent bulk density.
- It is known that the porosity of unfired ceramic pieces, which depends on the type of granules , the grain size and the grain size distribution, the proportion plastic material
- By analyzing the faults that occur most frequently in the manufacture of ceramic floor and wall tiles, it was found that many of these originate from or are influenced by the porosity of the unfired material or by the uneven distribution of the porosity.
- From the above, it will be clear that it is necessary to determine the exact value of the porosity during the production process. This can be done by measuring the density or strength and the volume of the pores.
- To enable an effective control of the strength, it is necessary
- To have adequate testing techniques available with regard to speed of execution of the test .
- To determine the maximum period between a fluctuation in the porosity of the unfired material and its distribution over the interior of the pieces, which is still permissible during the process and which consequently does not bring about significant changes in the quality of the finished product.
- To know the entire production process in detail so that, whatever the deviation in the strength of the unfired piece beyond the preset limits, it can be corrected quickly by adapting the parameters of the process (pressure, humidity) and, in case this would not be possible, adjust the firing in order to reduce the effects of this variation in strength.
TESTING METHOD:
- The most exact testing methods to determine the density in a dry way are based on measuring the volume of the samples by displacement of the volume of mercury or by the force which is required to immerse the sample in mercury.
- The method of the displacement of the volume of mercury as described by Stringer has been partly modified, in order to make it more convenient without changing its accuracy and reliability.
