Anti-static shoes and conductive shoes can be divided into leather shoes and cloth-soled shoes. The shoes can be divided into adhesives, injections, and molds according to the production process. Insulating shoes can be divided into leather shoes, cloth shoes, plastic shoes and plastic shoes. Leather shoes can be divided into adhesives, moldings, injections and seams according to the production process. Anti-static shoes are protective shoes that can eliminate static electricity accumulation in the human body and prevent electric shocks below 250V. Conductive shoes have good electrical conductivity and can eliminate the accumulation of static electricity in the human body in a short period of time. They can only be used in protective footwear where there is no danger of electric shock. Electrically insulating shoes are protective shoes that can insulate people's feet from charged objects and prevent electric shock.
Electrical performance protective footwear technical requirements
Anti-static shoes and conductive shoes according to GB 4385-1995 "anti-static shoes, conductive shoes Technical Requirements" provisions, the range of resistance values ​​are 100k ~ 1000M and not more than 100k. Among them, leather shoes should comply with the provisions of GB1002-1005; fabric rubber shoes should comply with HG/T2495 regulations. The main technical performance of anti-static shoes and conductive shoes, in addition to electrical performance, there are also standards such as outsole wear amount, adhesion strength of the strip and the upper, folding-resistant outer bottom, wear-resistant outer sole, and peeling strength of finished shoes.
Electrically insulating shoes shall comply with the GB12011-2000 General Technical Conditions for Electrically Insulating Shoes. The electrical properties of electrically insulating shoes and electrically insulating cloth shoes are: When the leakage current is 0.3 mA/kV, the requirements of Table 1 should be satisfied.
The electrical properties of the electrically insulating rubber boots and the electrically insulating polymeric boots are: When the leakage current is 0.4 mA/kV, the requirements of Table 2 should be satisfied.
The main technical performance of electrical insulating shoes in addition to electrical properties, there are adhesion strength of the upper and the fence, the tensile properties of the upper, the adhesive strength of the upper and the fabric, the folding resistance of the outsole, the wear resistance of the outsole, the peeling strength of the finished shoes, the water seepage Sex etc.
Electric performance protective shoes selection
The electrical performance protective footwear shall be equipped in accordance with the National Standard GB11651-1989 "Selection Rules for Labor Protective Products" and the "Standard for the Provision of Labor Protective Equipment (Trial)" issued by the State Economic and Trade Commission on March 6, 2000, or the relevant provisions of localities and industries. Execution, but also according to the type of protective injury and the working environment for selection, such as work environment, the main risk factors for electrostatic damage, and the work surface is conductive ground, consider using conductive shoes; and may be at the same time low voltage (under 250V) electric shock In hazardous workplaces where the work surface is anti-static, consider using anti-static shoes. Anti-static shoes and conductive shoes are mainly used in petrochemical, pharmaceutical and electronics industries. If the main risk factor in the work environment is electric shock, electrified shoes should be used when electrified.
In addition, users can choose different materials of electrical performance protective shoes according to the work environment. For example, in most of the electronics industry and pharmaceutical industry, the environment is cleaner and the work intensity is relatively low (less moving). Anti-static shoes or conductive shoes with cloth bottom may be used, which is light, comfortable and breathable. The petrochemical industry, including refueling (gas) stations, the work environment is more complex, work intensity is relatively high (more walking), can choose to use anti-static shoes or conductive shoes, more dirt and durable. Similarly, in live working places with a power frequency voltage of 1 kV or less, and the environment is relatively dry, electrical insulating shoes or electrical insulating cloth shoes with a withstand voltage of 15 kV or less can be selected. In the workplace where the power frequency voltage is 1kV or more, or where the environment is relatively humid, an electrically insulating rubber boots or an electrically insulated plastic boot having a withstand voltage of 15 kV or more may be used. In use, the provisions of the electrical safety working regulations (DL408 and DL409) must also be strictly observed.
Leather shoes, electrical performance protection shoes can also be based on the user's preferences, use different production processes and the appearance of quality products. At present, the more common is the glue and injection type shoes, line seam leather shoes for the majority of car and anti-wool insulation shoes, molded shoes are now rarely used. Appearance quality is generally easier to judge, such as whether the helper has disability, color is not the same, and the line re-needle, jump needle, broken line, pin code uneven.
