      Technical parameters

      Execution standard: ISO2811 GH6750-86-86

      Model: QBB - 100

      The cup body volume: 100 ml

      Material: aluminum

      Purpose: measure the density of paint, varnish

      Test technical features: the proportion of glass cup (mass/volume), within the prescribed measuring the temperature of liquid density, expressed as a g/ml

      Operation steps

      - the weight of the weighing and record the density of clean cup

      - adjust pycnometer and test the temperature of the paint

      - will detect varnish samples into the bottle

      - placed pycnometer and cover, squeeze bottle of bubbles

      - use absorbent cloth to overflow the varnish

      - weighing bottle full of testing varnish

      First,Application

      KeXin QBB-100 Specific Gravity Cup is based on GB6750-86 color paint and varnish density measurement and the design and manufacture.Used in measuring the temperature of liquid paint, varnish and relevant product density (or density).

      Second,Testing instrument

      1, Gravity Cup: made of aluminum alloy material, volume for 37 ml, 50 ml and 100 ml of QBB 30, 50, 100 - type coating pycnometer (mass/volume).

      2, thermometer: degree of 0.1 ° C, the accuracy of 0.2 ° C.

      3, water bath or constant temperature requirements:

      If you want test accuracy is high, you should keep the test temperature range of + / - 0.5, for production control shall be maintained in the temperature range of plus or minus 2 ° C.

      4, analytical balance (or electronic), precision can reach 0.2 milligrams (mg).

      Three, sampling

      Shall be conducted in accordance with the national standard GB3186-82.

      Four, test steps

      1, with no residue left after evaporation flux, cleaning, share a cup, and dry it.

      2, will share a cup of weighing at room temperature (the proportion of lid weighed together).The the difference between the two weighing data shall not be greater than 0.5 milligrams (mg).

      3, in the below test temperature, and no more than 1 ° C under the condition of the cup filled with distilled water.(strictly prevent bubbles) to place it in under the condition of constant temperature, until the cup and the proportion of the inclusion temperature constant.Using absorbent material, wipe the overflow material, and the proportion of outside of the cup.

      4, the proportion of weighing the immediately filled with distilled water cup, accurate to the quality of 0.001%.

      The determination of 5, the density of the test: by sample instead of distilled water, repeat the above steps.

      6, density calculation:

      Press type to calculate the density of sample under test temperature p1:

      p1=(m2-m0) / V

      formula: P1——density g/m1

                m2——the quality of Gravity Cup and the sample  g

                m0——empty Gravity Cup's quality  g

                V——Gravity Cup's volume  m1

                t——test temperature ° C

      Five, the volume of gravity cup calculation

      Due to environmental condition such as temperature, humidity, pressure change, the proportion of metal cup one's own physical and chemical properties, has the potential to share a cup of tiny changes in the volume.If you want high measuring accuracy, should calculate volume proportion of cup, periodic method is as follows:

      V=(m1-m0)/ p

      formula:V——Volume       m1

             m1——the quality of Gravity Cup and the water  g

             m0——empty Gravity Cup's quality  g

             p——density g/m1
