How to quickly distinguish anti static safety boots? This problem has always troubled consumers, especially during the peak period of purchasing labor insurance shoes. The dazzling array of labor insurance shoes will indeed cause headaches for many people. So how to distinguish anti static safety shoes? From the perspective of safety production, the foot is a part of the human body with a high injury rate. Today I will talk to you about how to quickly distinguish anti static safety boots, and give you some suggestions during the purchase process.
Generally, when we mention safety shoes, we first think of anti-smashing and anti-puncture safety shoes. In fact, in electronics factories, chemical factories, pharmaceutical factories, food factories, petroleum and other industries, in order to reduce the damage that static electricity may cause to instruments or human bodies, anti static safety boots will be worn.
Anti static safety boots add special materials to the soles and add conductive wires to the insoles, making the human body and the ground a “passage” that guides static electricity from the human body to the ground, thereby eliminating static electricity on the human body and effectively inhibiting personnel from being in the air without Dust generated by walking in the dust chamber. It is a kind of work shoes worn by production workshops and advanced laboratories of microelectronics industries such as pharmaceutical factories, chemical factories, electronic semiconductor devices, electronic computers, electronic communication equipment, and integrated circuits to reduce or eliminate electrostatic hazards.
So is there any way for us to distinguish anti static safety boots?
In the first way, we can check the anti-static logo of safety shoes. The logo of safety shoes is an important way to understand the information of a pair of safety shoes. Regular anti-static safety shoes will be clearly printed with: model, function, implementation standard, size, color, production date and other information.
The function of anti-static safety shoes must have “anti-static”, and the implementation standard is the new standard GB21148-2020. The resistance value of qualified anti-static shoes should be in the range of 0.5×10＾5Ω to 1.0×10＾8Ω. Anti-static shoes whose resistance value is not within this range will not have a good anti-static and dust-proof effect.
In the second way, we need to check whether the insole has anti-static material. A pair of anti-static safety shoes usually use anti-static materials in the insole, so whether the safety shoes have anti-static function, you can tell at a glance by taking the insole out.
Anti static safety boots have the function of evacuating charges, which can guide the excess charges of the human body to the ground, avoid electrostatic discharge caused by the accumulation of charges, and thus play the role of eliminating static electricity in the human body.
The third method is to check the appearance and inspection report of anti-static safety shoes. When we purchase in large quantities, we can first ask the manufacturer for a pair of sample shoes. When we get the samples, we should check whether there are defects in the upper surface, glue opening, color difference, etc.
Carefully check whether the production process of anti-static shoes meets the specifications. A pair of qualified anti-static shoes will not have obvious defects such as broken threads, uneven stitches, glue, and flaws on the upper surface. These small problems will affect the normal use of anti-static shoes. When purchasing anti-static shoes, pay attention to whether the shoes are beautiful Generous and meets the requirements.
In the purchase stage, you can also ask for relevant qualifications from anti static shoe manufacturers to see what qualifications they have, whether they are all within the validity period, and whether the names on the qualifications are consistent. You can view the corresponding product test report, and you can learn about the relevant functions of safety shoes and more detailed product information by viewing the test report.
Generally, the main materials of anti-static safety shoes are as follows:
1. SPU is a silicone-modified polyurethane material, and the SPU material is one-time molding. Because of its light and soft feel, light weight, and comfortable wearing, it is widely used and is very suitable for making anti-static slippers.The performance is in the middle, its performance and price are moderate, and it is an anti static shoe with high cost performance.
2.PU is a polyurethane material, which belongs to the category of leather. The anti-static shoes made of PU have a softer feel, strong flexibility, wear resistance, non-slip, soft and comfortable, and are suitable for long-term wearing and work. Its anti-static performance is relatively unstable and its price is relatively high.
3.PVC is polyvinyl chloride material, which is a synthetic plastic, rubber polymer, and belongs to the category of plastic. Anti-static shoes made of PVC material are hard to the touch, light in weight, wear-resistant, good in gloss, and easy to maintain. It has rich colors and is suitable for summer wear. The sole is thin and hard, and it is not suitable for practitioners who need to stand for a long time. . Its performance is relatively stable and its price is low.
When we choose the appropriate anti static safety boots, there is one thing that needs to be paid attention to at all times. In the process of wearing anti static safety shoes, it must be matched with anti-static work clothes. Only in this way can the effect of static electricity be prevented more effectively. And you must not wear thicker socks, nor wool socks, let alone insoles, so as to maximize the effect of anti static shoes.
