QBB Specific Gravity Cup
يستخدم:
QBB type paint specific gravity cup is designed and manufactured according to GB6750-86 “Determination of color Paint and Varnish Density”.Used to determine the density (or specific gravity) of liquid paints, varnishes and related products at specified temperatures.
Instruments For Testing
(1) Specific gravity cup: QBB-37, 50 و 100 type coating specific gravity cup (mass/volume cup) made of aluminum alloy (stainless steel) with volume of 37mL, 50ml and 100mL;
(2) Thermometer: degree 0.1°C, accuracy 0.2°C;
(3) Requirements for water bath or constant temperature: If high test accuracy is required, it should be kept within the range of ±0.5°C of test temperature, and ±0.2°C of test temperature for production control;
(4) Analytical balance (or electronic scale) : the accuracy should reach 0.2 ملغ.
أخذ العينات
According to GB3186-82 provisions of the implementation.
