How does a shoe break have advantages over traditional shoes? What environment is it used for? If the friends who do not understand the shoes will have the above question, the anti - shoe is a kind of shoe that can protect the toe from external injury, prevent piercing, acid alkali and insulation and so on, generally applicable to the working environment dangerous staff. According to the different protective properties, it can also be divided into many categories, such as antistatic, insulation, anti smashing, anti slip, anti piercing and other properties. Then what kind of wear performance do you usually have to break shoes? Let's get to know it now.
(1) anti impact performance of Baotou: in the impact test of the specified heavy steel hammer, the height of the gap in Baotou under the impact of Baotou should be less than the specified value, and the Baotou should not appear any penetrating cracks in the axis direction of the test. It is important to pay attention to the difference in the weight, specifications, impact height and the structure of the test machine, so the actual test should be distinguished in the actual test.
(2) resistance to piercing performance: the experimental machine is equipped with a pressure plate with an experimental nail on the press plate. The experimental nail is a head of cutting off the tip, and the hardness of the nail head should be greater than 60HRC. The shoe sole specimen is placed on the chassis of the experimental machine. The position can stop the test nail through the outer bottom and pierce the sole with the speed of 10 mm/min + 3 mm/min, until the penetrating force is recorded. 4 points are selected on each sole to stop the experiment (at least 1 points in the heel). The distances between the points are not less than 30mm, and the interval from the bottom edge to the bottom is greater than 10 mm. The bottom of the anti slide block should be punctured between blocks. The 2 points in the 4 points should be stopped at the interval of 10-15 mm from the edge line of the planting floor. If humidity can affect the result, the shoe sole should be immersed in the deionized water at 20 + 2 1H before testing. 16 +.
(3) electrical properties of conductive shoes and antistatic shoes: after being adjusted in a dry and wet atmosphere, the shoes are filled with a clean steel ball and placed on a metal probe installation, and the resistance of the first two probes and third probes is measured by a regular resistance test instrument. Under normal circumstances, conductive shoes require resistance not greater than l00K ohms, while antistatic shoes require between 100K ohms and 1000M ohms.
