阻燃、 抗静电－挂钩的抗静电及阻燃成分均匀分布在挂钩本体内，因而抗静电及阻燃性能指标不会因时间而受 到影响，抗静电及阻燃性能均符合煤矿行业标准，适用于井下易燃、易爆的工作场所。 The anti static and flame retardant components of the flame retardant and antistatic hook are evenly distributed in the hook, so the anti static and flame retardant properties are not affected by the time. The antistatic and flame retardant properties are all in accordance with the standard of the coal mine industry, and are suitable for the combustible and explosive workplaces in the underground. 质轻、安装方便—挂钩密度小、重量轻、成本低、运输、安全方便，用在井下安装时不仅能降低工人劳动强度， 提高工作效率，而且工程造价低。 Light quality, easy installation - small density, light weight, low cost, transportation, safety and convenience, used in the downhole installation not only can reduce labor intensity, improve work efficiency, and low cost of the project. 抗老化、耐腐蚀—挂钩抗老化性能好，不易脆化，具有良好的韧性，吸收冲击力。 Anti aging, corrosion resistance - hook aging resistance is good, not easy to embrittlement, good toughness, absorb impact force. 使 用 寿 命 长 —在正常条件下使用，寿命可达到50年。 Long service life - life expectancy can be up to 50 years under normal conditions.
