6. Structure composition and principle
It is mainly composed of main engine, pressure head, loading device, deformation acquisition system, micro-processing system and so on.
Micro - processing system deformation acquisition system.
Color crystal touch screen head.
Plastic hardness refers to the ability of plastic materials to resist another rigid object that does not produce elasticity and plastic deformation.
The hardness test of plastic ball indentation is to press the steel ball with the specified diameter to the surface of the sample under the action of the test load, and then read the depth of the indentation after a certain period of time.The hardness value is obtained by calculating or checking the table.
1. The thickness of the sample is not less than 4mm. The adjustable range of the loading speed is 2-7 seconds, usually 4-6 seconds, and the loading time is 30 seconds or 60 seconds.The load size should be selected according to the expected hardness of the sample.Instead, take a smaller load.If the hardness of the sample cannot be predicted, it must be gradually upgraded from the smaller load, so that the ball pressure head and sample will not be damaged.Generally, the test can be carried out by selecting the load according to the sample requirements.
2, the ball indentation hardness refers to regulation of the diameter of the steel ball, the test load under the action of vertical pressure into the surface of the sample, keep a certain amount of time, per unit area of average pressure Kgf/was or N/was said.
Its expression is:
H = 0.21p / 0.25 (H -0.04) (kg/ mm2)
P - load (kg)
H - indentation depth (mm)
D - ball diameter (mm)
PI PI -
Note: h = h1-h2
H1: pressure depth of sample load (mm);
H2: rack deformation under test load (mm)

7.Sample requirements.
1. The sample should be uniform thickness, smooth and smooth surface, no bubble, no mechanical damage and impurities.
2. The thickness of the sample should not be less than 4mm, and the sample size should ensure that the distance between each measuring point center and the sample edge is not less than 10mm, and the distance between each measuring point center is not less than 10mm.The recommended sample size for 40 * 40 * 4 mm or Ф 50 x 4 mm.
