油船油舱卸油扫舱时,要经常进行检测残油深度。在操作时,为了防止静电放电引起爆炸火灾事故发生,要求测深杆及其系绳既有阻燃性,同时还必须具有抗静电防爆性能。为此,我们采用特种材料和工艺,研制出一种新型的、阻燃、抗静电和防爆的测深杆及其系绳。 When tanker oil tanks are unloaded and stripped, the depth of residual oil is often checked. During the operation, in order to prevent the electrostatic discharge from causing an explosion and fire accident, the sounding rod and its tether are required to have both flame retardancy and antistatic and explosion-proof performance. To this end, we have developed a novel, flame-retardant, anti-static and explosion-proof sounding rod and its tether using special materials and processes.
