Description

Technical Field

[0001] The utility model belongs to the technical field of water-based emulsion solid content testing, and more specifically relates to a water-based emulsion solid content testing device. Background Art

[0002] Solid content test is an important performance parameter for testing water-based emulsions, such as acrylic emulsions. When testing solid content, it is necessary to bake an aluminum foil dish with a diameter of about 75 mm in a blast oven at a specific temperature, generally 105-150°C for 15 minutes, and then cool it to room temperature in a dryer, weigh it, and record it as m0, accurate to 1 mg. Then, weigh about 3g of the test sample in the aluminum foil dish with the same accuracy, and the weight of the aluminum foil dish containing the test sample at this time is recorded as m1. Put the aluminum foil dish containing the test sample into a blast oven preheated to the specified temperature, keep it for 30 minutes, take out the aluminum foil dish after drying, cool it to room temperature in a dryer, and weigh it again, and its weight is recorded as m2. Based on the above test, the solid content is calculated by the following formula: solid content = (m2-m0) / (m1-m0)x100%.
