How to divide the grade of anti-cut gloves
1. How to divide the grade of anti-cut gloves
The classification of cut-resistant gloves is based on the EU BS EN 388 (equivalent to the Australian/New Zealand standard AS/NZS 2161.3). The standard specification covers 4 mechanical risks. They are anti-wear, anti-cut, anti-tear and anti-stab. Gloves that meet the specifications shall be marked with a shield emblem with the image of a blacksmith hammering iron. And express the protection level from 1 to 4. Some cut-resistant gloves have a cut-resistant rating of up to a maximum of 5. Sometimes "x" and "0" are also used. Indicate not applicable and rated below "1", respectively. Cut resistant gloves must also meet the general, comfort and efficiency, test procedures and labelling and information requirements set out in BS EN 420. For example, the penetration of water, the amount of hexavalent chromium released from leather gloves, etc.
The cut-resistant test process for cut-resistant gloves is to take a sample from the palm of the glove. Cross-cut back and forth with tungsten steel rotary cutter. And record the number of revolutions required to cut through the sample. To compare the results of the standard cotton samples tested while staggered. The calculated index is higher. The stronger the anti-cutting performance. However, the cut resistance test is not suitable for very hard materials.
2. What are the materials of anti-cut gloves
1. Kevlar (Aramid): Aramid is an aromatic polyamide product. The primary color of the fiber is yellow. Strong and lightweight. flexible. 5 times stronger than steel of the same weight. Fireproof. Will not melt at high temperatures. Therefore, it is more suitable for high temperature workers. For example: metal smelting, industrial welding, glass processing, etc.
2. Dyneema/Spectra (high-strength polyethylene fiber): tough and lightweight. Good fit. Good abrasion resistance. The coefficient of friction is small. high strength. It is more than ten times that of steel wires of the same section. Mostly used for high-intensity industrial workers. For example: metalworking, body assembly, stamping operations, etc.
3. Steel wire and polyester fiber: Steel wire gloves have the highest cutting resistance. A blade suitable for human operation. Except in the food processing industry. Also used to defend against animal bites.
Third, the performance of cut-resistant gloves
1. Anti-cut, anti-stab, anti-skid, wear-resistant.
2. It has super cutting resistance, abrasion resistance and stab resistance.
3. It can effectively protect human hands from being cut by sharp blades such as knives.
4. Excellent anti-slip performance can protect objects from falling when grabbing.
