Hubei Xingfa Chemicals Group Co., Ltd., CNOOC Tianjin Chemical Research & Design Institute. The main drafters of this standard. Li Guangming Xiong Ping. This standard is the first release. Determination of Inorganic chemical products bulk density

1 Scope

This standard specifies the method for determination of the principles of inorganic chemical products in bulk density, instruments, analytical procedures and the results of calculations. This standard applies to the determination of bulk density greater than 45μm particle size of inorganic chemical products.

2 principle of the method

An amount of the sample through a conical funnel, the free fall of a known volume of a cylindrical bucket, the bucket filled accurately weighed sample of the substance Amount, calculated to obtain a test sample of the bulk density.

3 Instrument

3.1 bulk density measuring device material. glass, plastic, stainless steel. 3.2 Bulk density measuring device. 1. 1 --- tank; 2 --- scaffold; 3 --- funnel. Figure 1 Bulk density measuring device 3.3 Determination of tank volume 3.3.1 Determination The tank wash, dry, covered with glass, weighing bucket and quality of glass. Carefully pour water into the tank, nearly full when applied with a dropper Water to the full, covered with glass. With filter paper and glass exterior of the tank water, glass and feed tank should be no air bubbles between the horizontal plane and then Weigh the tank and the glass sheet. 3.3.2 density of water and temperature parameters 3.3.2.1 Table 1 shows the 10 ℃ ~ 27 ℃ water density parameter. ......
