1 Scope
This standard specifies the determination of wood-plastic composite materials and their products density or bulk density determination of the terms and definitions, principles, equipment
Preparation, test procedure, result calculation and test report.
This standard applies to foam and unfoamed WPC composites and their products.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 2918-1998 plastic sample conditioning and testing of the standard environment
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Density density
At a certain temperature the quality of the sample and its volume ratio.
Note. Units are expressed in kg/m3 or g/cm3.
3.2
Bulk density
Contains the volume of unit volume at a given temperature in the state of open volume and closed porosity.
Note. Units are expressed in kg/m3 or g/cm3.
4 principle
Test the quality of the sample in the air with an analytical balance and then immerse the sample completely in water to test its quality in water. The sample is completely immersed
In water, the quality of its water is less than in the air, the mass reduction is equal to the quality of the sample water, the volume of water is equal to the test
Kind of volume The ratio of the mass of the sample in air to the volume of the sample is the density of the sample (bulk density).
5 equipment
5.1 Test device
Mainly by the analytical balance, impregnation containers and immersion cages and other components, as shown in Figure 1.
