In the daily production of enterprises, security accidents are everywhere, and a little negligence will bring huge harm to enterprises and employees themselves. In these injuries, because the employees' feet are usually at the lowest part of the working posture, the workers will be exposed to heavy, hard, angular objects at any time during the use of tools, operating machines, and moving materials, so that both feet Being injured and stabbed, it is especially important for the protection of employees' feet. The company can effectively prevent this kind of injury by selecting special suitable safety shoes according to the working conditions.
In a large number of metal stamping, mold plating, machinery manufacturing, and steel shipbuilding production workshops, due to the inherent characteristics of the industry, there will always be a lot of hard and sharp foreign objects scattered on the floor of the workshop, in such a working environment. A pair of anti-piercing safety shoes can provide adequate protection. So, what is puncture-proof safety shoes?
The anti-piercing safety shoes are equipped with a 0.05mm degreased stainless steel middle sole plate on the sole to prevent the sharp hard objects such as nails from piercing the outsole of the shoe and hurt the soles of the enterprise workers. The anti-piercing force is greater than 1100 Newtons. In line with national standard GB21148-2007, it is a special strength. Mainly used in mining, machinery, construction, metallurgy, harvesting, transportation and other industries.
Anti-piercing safety shoes are generally equipped with anti-piercing and anti-smashing functions, but they can't be matched with insulation function. Because the insulated shoes are related to the safety of the employees, the soles can not be destroyed. If the insulation sole is damaged, stop using it immediately. Also pay attention to waterproof, water will be conductive, and it is dangerous to use in a charged environment.
Anti-puncture detection method: The test machine is equipped with a pressure plate, and the test plate is provided with a test nail. The test nail is a tip with a cut-off tip, and the hardness of the nail head should be greater than 60HRC. The sole sample is placed on the chassis of the testing machine in such a position that the test nail can be pierced through the outsole, and the test nail pierces the sole at a speed of 10 mm/min ± 3 mm/min until the penetration is completed. The greatest strength. Four points are selected on each sole for testing (at least one of which is at the heel), each point is not less than 30 mm apart, and the distance from the insole edge is greater than 10 mm. The bottom of the anti-slip block should be pierced between the blocks. Two of the four points should be tested within 10-15 mm of the edge line of the planting raft, recording the maximum force at each point of penetration. If humidity affects the results, the sole should be immersed in deionized water at 20 °C ± 2 °C for 16 ± 1 h before testing. .
