Anti Arc Principle of Anti Arc Fabric

With the rapid development of industry, there are more and more electric arc injury accidents. In the face of this situation, if the scene personnel wear clothing with fire protection and thermal protection performance, the greater hope of escape and rescue in the disaster, the less hurt. Therefore, the anti arc clothing has effectively solved the safety problems of the operators in the power and chemical industry for a long time, and greatly reduced the damage probability of the electric arc to the operators. Anti arc clothing is suitable for electric power and social enterprises and institutions of full-time or part-time electric power staff daily work, potential arc environment (but not suitable for the use of chemical dangerous products, gas, nuclear radiation and other special environmental use wear), electric arc explosion accident escape wear. The protective effect of anti arc clothing is based on the principle of arc discharge. The main reason to resist arc damage is that the anti arc clothing is made of high-tech materials. The material has the characteristics of heat resistance, flame retardant, no combustion, no melting and H grade electrical insulation, and so on. In the event of an arc explosion, this high tech material expands rapidly and carbonizes the fabric so that the density of the structure of the anti arc clothing is increased and thickened, and the protective layer is quickly formed, thus minimizing the contact injury between the human skin and the heat of the arc. Special functions determine the excellent characteristics of anti arc clothing, such as lightweight, breathable, moisture permeable, permanent antistatic, healthy and environmental protection.

1. The measure of the strength of the arc (ATPV, Arc Thermal Performance Value) is a unit of Cal/cm2 (calorie per square centimeter); it refers to the total energy in one unit area and is used to detect the strength of the arc. The exposure energy of 1 Cal/cm2 is equivalent to a lighted cigarette butt on the fingertip for 1 seconds, as long as 1-2 Cal/cm2 will cause 2 degree burns to human skin. According to the American NFPA Association, it is known that arc injuries are mainly caused by the huge heat energy produced by arc explosions that cause burns to the human body, so the standard for measuring the possible damage to the arc is usually the use of electric arc energy standards, that is, Cal/cm2 (calorie per square centimeter). The greater the ATPV value of anti arc clothing, the better the arc proof performance.

2. Layer number structure of anti arc clothing

A. 5cal (210g/m2), 9.1cal (230g/m2), 15.5cal (270g/m2) single layer permanent flame retardant fabric material: anti arc fabric blended with aramid fiber and FR-VISCOSE, and the materials used are permanent flame retardant materials.

B. 22cal double layer permanent flame retardant fabric products

C. 35cal three layer permanent flame retardant fabric products material: anti arc fabric made of material, the material used as permanent flame retardant material for arc products through advanced production technology, the use of permanent flame retardant sewing thread car seam, so that this product to prevent arc, flame retardant, heat insulation, breathability, comfort and other excellent performance.

3. Excellent characteristics of anti arc clothing

1) Light: under the same protection level, the anti arc clothing is lighter than the clothing that has the protective performance after the treatment and is lighter than the other imported permanent flame retardant materials. Under the same weight of material, the protection level of anti arc clothing is much higher than that of other similar products.

2) Breathable and moisture permeable: anti arc fabric contains natural plant fiber, which has excellent breathability and moisture permeability and is more comfortable to wear.

3) Permanent anti static electricity: similar products are woven in fabrics such as conductive silk, conductive wire will be broken because of washing, loss and loss of anti static function, direct mixing of conductive fiber in anti arc fabric, permanent anti static.

4) Healthy and environmental protection: the past anti arc clothing usually use the chemical reagents after treatment to achieve the anti - arc properties of the fabric, free formaldehyde is easy to cause allergies and other symptoms, not conducive to the health of the human body. The anti arc clothing uses advanced raw materials and does not need any chemical treatment, which ensures the wearer's health from the source.

4. The main points of washing should be dried as soon as possible after being wet. If there is any stain, wash it as soon as possible, remove stains and dry it, so as to avoid moldy or produce germs. Machine washable or hand washing. Please use neutral detergent as far as possible. Do not wash with other clothes. Water temperature is 40-48 degrees Celsius. Please do not use bleach and softener. Avoid prolonged exposure to exposure or fluorescent lamps to prevent damage to the performance of clothing. Oil stains, blood stains and other serious stains, before washing, please apply dry cleaning agent, hand rubbing or brush to clean and rinse with clean water. After cleaning the blood, use disinfectant to disinfect.
