Overview
The SHIBO QBB-37 Coating Specific Gravity Cup is a special testing instrument designed and manufactured according to the GB6750-86 standard for the determination of the density (specific gravity) of liquid Paints, varnishes and related products at the specified temperature. The product is made of aluminum alloy and has a standard volume of 37ml. It is suitable for accurate measurement at 23 ° C.
Features
1. Designed and manufactured according to the national standard GB6750-86, the measurement results are accurate and reliable
2. Made of high-quality aluminum alloy, strong and durable
Standard 37ml volume design to meet accurate measurement requirements
4. Suitable for standard measurement temperature conditions at 23 ° C
5. Reasonable structure design and easy operation
Principle
Coating Specific Gravity Cup calculates the density of the sample by measuring the mass difference between the cup body in the empty cup state and the full sample state. The calculation formula is p1 = (m2-m0)/V, where p1 is density, m2 is Specific Gravity Cup and sample mass, m0 is empty Specific Gravity Cup mass, and V is Specific Gravity Cup volume.
Applications
Paints density determination, varnish density determination, Coating related product density determination
Standards
GB6750-86、GB3186-82
Steps
1. Clean the Specific Gravity Cup with a flux that does not leave residue after evaporation and dry it
2. Weigh the Specific Gravity Cup (including cover) at room temperature, the difference between the two weighing data must not be greater than 0.5mg
3. Fill the distillation water with no more than 1 ° C below the test temperature and place it under thermostatic conditions until the temperature is constant
4. Wipe off the overflow material and the outside of the cup body, and immediately weigh the Specific Gravity Cup filled with distillation water
5. Using the sample instead of distillation water repeability above operation steps
6. Calculate the sample density according to the formula p1 = (m2-m0)/V
Notice
• Specific Gravity Cup needs to be cleaned and put into the box after use
Should be stored in a room temperature environment
• Strictly prevent bubbles during measurement
• If the Measurement accuracy is very high, the Specific Gravity Cup volume should be calculated in stages
• Weighing should be accurate to 0.001% of the mass
