1. Question: Does the specific gravity cup need to be calibrated?
Answer: Hello, regular calibration can ensure the measurement accuracy of the specific gravity cup, refer to calibration once a year. But it varies from scene to scene .
2. Question: What is the difference between the specific gravity cup made of aluminum and stainless steel? How to choose?
Answer: Hello! In principle, there is no difference in the specific gravity cup test, and you can choose a better specific gravity cup material according to the fluid material to be tested.
3. Question: How to use the paint specific gravity cup?
Answer: Hello, first of all, weigh the empty pycnometer m1 with the cover on the balance; then put the sample into the pycnometer and cover it, weigh it with the balance, and record the weight m2 of the pycnometer filled with the sample. Then calculate the density of the paint sample according to the density formula.
4. Question: Calcium carbonate mud belongs to paint. I want to know whether it can be tested with our specific gravity cup?
Answer: Hello! In theory, fluids can pass the specific gravity cup test.
5. Question: Is there any regulation on the weight of the 100ml specific gravity cup?
Answer: Hello! There is no regulation.
6. Question: I don’t know why the specific gravity is converted in this way. For TQC, the specific gravity=(M liquid-M empty cup)% volume density is the specific gravity?
Answer: Hello! If the unit is different, it needs to be converted. Specific gravity=density=mass/volume (unit: g/ml)
The original density calculation is XXg/50mL. If you need to use "g/L" (gram/liter) as the unit for density, you need to convert it like this: 1L=1000mL, and the density calculation is XXg/50mL*1000=XXg*20.
7. Question: Can the specific gravity cup be used to measure the coating base material? The base material made of paint waste residue has a solid content of only about 20%
Answer: Hello! Can be tested, general viscosity fluid can be tested.
8. Question: I measure the liquid here, and the powdery materials have red lead powder, the bulk density, the fluidity is not big, and the specific gravity is large.
Answer: Hello! According to your needs, what you are measuring should be the bulk density of the powder. I recommend you a natural bulk density meter. I will send you the product information and quotation.
