[0002] Nano calcium carbonate is a form of calcium carbonate. As a structural and functional filler of silicone sealant, nano calcium carbonate powder greatly improves the adhesion, tensile properties, tear resistance, etc. of the sealant. Various properties of nano calcium carbonate such as particle size, specific surface area, mass loss rate and crystal form, pH value, magnesium content, oil absorption value and moisture content all have a certain influence on the performance of the sealant. If the pH value of nano calcium carbonate is too high, it will affect the storage performance of the sealant. Therefore, in the production of nano calcium carbonate powder, it is necessary to test its pH value. Usually, the pH value of nano calcium carbonate powder is tested by an acidity meter for testing nano calcium carbonate powder.

[0003] When a common acidometer for detecting nano calcium carbonate powder is used to detect the pH value of nano calcium carbonate powder, the nano calcium carbonate powder is usually placed in a beaker. After titration of a specific solution and mixing and stirring, a calibrated electrode rod is placed in the beaker. During this process, the beaker is usually exposed to the outside. Substances in the air may affect the detection result of the nano calcium carbonate powder, and the degree of sufficient stirring of the nano calcium carbonate powder solution may also affect the detection result of the nano calcium carbonate powder.
