Technical data of QL-120T/GP-120T/MH-300T for Powder

True Density :

Powder true density is one of the physical properties of powder materials; it’s an indispensable parameter for testing the particle size and porosity of Powder.

1. The data of powder true density is needed when calculating the specific surface area of powder.

2. Lots of non-metallic inorganic materials are made of powder, thus measuring true density is necessary in the fields of scientific research and manufacture.

3. In the fields of cement or ceramic materials, the data of powder true density is also needed when testing the clay’s particle distribution and slurry’s fineness.

4. For cement material, testing cement true density is meaningful to both the production department and users.

5. Shorten the traditional testing time for true density of refractory materials, it can show the testing result without any redundant calculation.

Testing conditions:

1.    Under immersed method, choosing the liquid which can not dissolve but can moisture the sample surface is important.

2.    For ceramic materials, such as feldspar, quartz and ceramic products, distilled water can be used as liquid medium.

3.    When testing the materials which have chemical function with water, such as cement, kerosene or xylene and other organic liquid can be used as testing medium.

4.    For inorganic powder, organic liquid also can be chosen.

5.    The bubbles need to be removed when powder immersed in the liquid totally, then the excluded volume can be confirmed.

6.    By using porcelain mortar to rub powder and filter it by 240 mesh sieve, then put the powder in the weighing bottle, and dry it by moisture meter under 105℃, take out and cool it to room temperature in desiccator.
