The problem of measuring the density of the film of the film faced plywood (or melamine Paper )
Life of commonly used paper, usually with the “gram” to indicate its thickness. For example, notebook paper is generally used 80g~120g paper (the film of the film faced plywood generally have 240g and 120g). Because the thickness of paper is uniform, we do not need to mass per unit of volume measurement, only need to know he per unit area of the quality can be, and mass per unit area called “density”. As for linear materials with uniform thickness, we often only consider the mass of the unit length, that is, the linear density”. Textbook printing paper is about 60g, its meaning is 60g/m2.
Usually we are in the domestic use of the construction of the film of the film faced plywood, is also processed by kraft paper, also follow this principle, when you read this section of the material, please do the following activities:
(1) to design a method for measuring the density of the film of the film faced plywood.
Materials required for experiment:
