A special vehicle company purchased a batch of anti static rubber sheets with a thickness of 5mm from ORIENTFLEX in May this year, which were used for the matching laying on the box of the explosion-proof vehicle truck produced by the company. Recently, due to the production needs of the pre-packaged engine transportation system, additional purchases one more time. Why do anti-static rubber sheets meet the needs of electrostatic safety protection for explosion-proof vehicles? What are the anti-static performance requirements of explosion-proof transport vehicles?
“QC∕T993-2015 Explosive Goods Transport Vehicle” and many other operating standards have a clear definition of static conductive rubber sheet, which requires a resistance value of 5*10 4th ohm-1*10 8th ohm. In our usual definition, this resistance value range is an anti-static/conductive rubber pad with both static dissipative and static conductive.
The reason why the customer chooses the 5mm thick anti-static rubber sheet is that in addition to the control of preventing sparks from electrostatic discharge, it is also necessary to take into account that the material should have better buffering capacity. Because in the process of circulation, flammable and explosive products may inevitably be In the event of collisions, bumps and other object movements, it is necessary to control the impact-type movement and absolutely not allow it to generate impact heat energy that reaches the minimum detonation capability.
And 5mm thickness, compared with 2mm, 3mm and other rubber materials with the same hardness, the buffer capacity is stronger. In addition to the basic anti-static properties, anti-static rubber mats also have non-flammability and flame retardancy, and the combustion performance level can reach B1 level, so they are widely used in dangerous goods storage, dangerous goods transportation, mines, gas stations, etc. Flammable and explosive areas.
