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 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 will not be 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 flammable and explosive downhole. 工作场所。 Workplace. 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 has good aging resistance and is not brittle, and has good toughness and absorb impact force. 使用寿命长—在正常条件下使用，寿命可达到500年。 Long service life, under normal conditions, the life can reach 500 years.
