Product Name: Safety shoes Product features: low to help the economy leather safety shoes: import embossed leather, permeability, super tear-resistant lining: quality new breathable mesh, high strength, high wear resistance, moisture absorption, soft comfortable and breathable Sole: Polyurethane / PU material, damping, reinforcing buffer, kept permanently elastic steel head: made of imported steel electrostatic spraying widened head, high strength, in line with GB21148-1997 standard bottom mold: special groove design, non-slip, oil, seismic, generous, athletic Optional features: Anti-smashing, anti-puncture, anti-static, insulation, acid, high temperature basic functions: Anti-smashing, acid safety shoes safety class shoes and protective footwear category referred to, generally refers to In the workplace wearing different shoes to protect feet and legs have from foreseeable harm. Safety shoes belong to high-tech and high value-added footwear, safety footwear production process requirements for raw materials, auxiliary materials, chemical materials, machinery and equipment are very high, the current domestic many of a certain size and grade of footwear enterprise has set its sights safety shoes used to be occupied by this developed markets. Safety shoes standards? European standard EN345 "special security, protection and work shoes [1]?" This European standard developed by CEN / TC61 "foot and leg protective equipment," Technical Committee, its secretariat held by BSI. The standard safety footwear models design, the entire shoe uppers, shoes, tongue, insole, outsole structure and performance indicators and other provisions. Each item specified in the standard test method is similar to other similar standards, the principle of the method is also generally applicable to most safety shoes, the main indicators for the header impact performance? Impact test with a predetermined weight of a steel hammer, by the impact of Baotou When the header at the height of the gap should be less than a predetermined value, and Baotou in the axial direction of the test shall show no penetrating cracks. It is noteworthy that the national standards for the hammer weight, size, structure and other provisions of the height and impact test machine is different, should be distinguished from the actual test puncture resistance? Fitted with a plate on the test machine, equipped with a test on the platen nails, nail a truncated tip of the test head, nailhead hardness greater than 60HRC. The test sample is placed on the sole machine chassis, the position of the test nails can be pierced through the outsole, in order to test the nail 10? Mm / min? ±? 3? Mm / min speed piercing soles, up until penetration record the maximum force required. Each election sole 4-point test (which has at least one point in the heel), each point distance of not less than 30mm, and the distance from the edge of the insole is greater than 10? Mm. There nonslip bottom, should be between blocks pierced. 4 points in two points should be planted away from the bottom edge of the flute line where 10-15? Mm distance for testing. If the humidity will affect the results, the test should be the sole immersed before adding 20 ℃ ± 2 ℃ deionized water 16 ± 1h. Anti-static shoes can? Shoe after drying and wet atmosphere adjustment, clean ball filled into the shoes and put on a metal probe device, using a predetermined resistance test instruments, measuring the first two probes and the resistance between the third probe. In general, conductive shoes requires resistance should not exceed l00K ohms;? Should be between 100K ohm to 100M ohm resistor antistatic footwear requirements. Heel performance? Test Instruments maximum compressive load 6000N, with a record load / deformation characteristics of the device. The band with the kind of shoes placed on a steel plate, the test center punch on the inside of the heel against the inner portion of the bottom. In 10mm / min with disabilities 3? Mm / min speed applied load. Draw load / compression curve, and calculate the absorbed energy E, expressed in joules. The standard anti-skid requirements? Specified slip coefficient test soles, but nonslip design, specifications makes provision for the sole thickness, nonslip height, distance from the edge of the sole, etc. are requested. With the development of China's shoe technology continues to progress and the growing global shoe materials update, safety footwear varieties gradually diversified gentrification. Internal security shoe design and technical requirements start with foreign gradual integration, the use of computerized management, sub electrical insulation, anti-static, acid, anti-piercing, toe protection, protective footwear generally six categories, with good oil, anti-smashing, anti-static, anti-puncture, acid and insulation properties, divided SB / SBP / S1 / S1P / S2 / S3 six security level, widely used in machinery, metallurgy, construction, chemical, pharmaceutical, mining, oil , electricity and other industries. Have been the company process quality control and factory rigorous testing each pair of shoes, in line with national safety standards (most indicators than the national standard) and the European standard EN345 safety shoes, domestic products have been more than 500 industrial and mining enterprises, especially in Europe and America joint venture of all ages, and exported to the EU, US, and Australia, and other countries in the region. Safety shoes? Function: safety shoes safety class shoes and protective footwear categories collectively, generally refers to the different work situations have worn shoes to protect feet and legs against foreseeable harm. As China's shoe-making technology continues to progress as well as the increasingly global shoe updated material safety footwear gradually diversify varieties, gentrification. Internal security shoe design and technical requirements start with foreign gradual integration, the use of computerized management, sub electrical insulation, anti-static, acid, anti-piercing, toe protection, protective footwear generally six categories, with good oil, anti-smashing, anti-static, anti-puncture, acid and insulation properties, different safety shoes scope of functional requirements for safety shoes are also different, specific performance: · protect the toe safety shoes: safety performance within Baotou AN1 grade, used in metallurgy, mining, forestry, port, handling, quarrying machinery, construction, petroleum, chemical industry and so on. · Anti-piercing safety shoes: Anti-piercing strength of one, for mining, fire, construction, forestry, cold work, and machinery industries, such as anti-smashing industry standard (protective toe safety shoes LD50-94), protected? toe safety shoes lined steel header, both static and impact-resistant properties, stab, anti-smashing, very safe, the test, resistance to pressure 10KN, hammer toe impact resistance 23KG high degree of freedom from 450MM After the fall impact toe shoes deformation space> = 15MM, mainly for mining, construction machinery safety, metallurgy, iron and steel, port lifting and other heavy industries, played the protection of safety toe shoes, there are rubber and elastomer body support, comfort, and does not affect their daily work operations. Anti-puncture protection from sharp objects stabbed feet, maximum puncture force can withstand 1100N, the national premium standards. Anti-static? Anti-static shoes produced according to GB4385-1995 standard resistance values ??ranging 100K'Ω-1000M'Ω, the product has good air permeability, anti-static, wear-resistant, anti-skid function, mainly used in aviation, aerospace crisis of an industry played avoid explosive accident occurred due to static electricity. Oil according to standard test oil, no more than 12% volume increase. If the volume does not increase, but narrow, narrow its large increase in the original volume of 0.5% or greater than 10 hardness (Shore A), according to GB / T? 3903.1 provision flex crack growth of not more than 40,000 times 7mm safety shoes maintenance? Safety shoes need proper use and maintenance, to ensure that users achieve the desired performance and maintain foot health, and therefore should pay more attention to the following matters: 1. Safety shoes are not allowed to modify the configuration. 2 wearing the right size of safety shoes, help maintain the wearer's foot health and durability of footwear. 3. pay attention to personal hygiene, the user shall be maintained clean and dry feet and soles. 4. Periodically clean the Safety shoes, but should not be used as a solvent cleaners. In addition, the soles should also be kept clean to prevent the accumulation of dirt matter, because the soles of conductive or antistatic performance will suffer matter how much dirt is stuck and bent circumstances affected. 5. Safety shoes stored in a cool, dry, well-ventilated place.
