"Test the density of cellulose acetate"

If you want to test the density of cellulose acetate, you must first understand its material properties. This ester is formed by the phase of acetic acid and cellulose, and its properties are different from ordinary materials.

Look at its shape, color or light or dark, depending on the process. Its state is either firm or nearly flexible, all of which are related to the ratio of acetic acid and cellulose and the treatment method.

If you want to measure its density, you should follow the scientific method. Take an appropriate amount of its material, clean it, and remove its impurities. With a precise device, measure its volume, and use the method of drainage to measure the amount of its discharge into the water to know its body. Compound the weight of the device, and call it the quality, and it must be fine.

Divide the mass by the volume, and the number is the density of cellulose acetate. However, this number is not constant, and the purity, temperature, and humidity of the additional teaching material vary. When the temperature rises, the molecule becomes dramatic, or the density decreases slightly; when the humidity increases, or there is an appearance of moisture absorption, it can also change the value of its density.

Therefore, when considering the density of cellulose acetate, it is not just a value. It is necessary to observe the causes in detail before we can know the change of its properties, which is good for use.
