Liquefied petroleum gas station misfire ground ( No spark fine stone concrete) practice

Not firing practice ground fine stone concrete action is not angry angry the cost of the ground is an emerging economy, has a certain strength of misfire structure material, according to the structural material properties can be divided into two categories, namely the misfire ground metal and non-metallic surface not to get angry. Cement mortar (misfire ground material not to get angry Not firing mortar) And don't get angry please call - fine stone concrete 15838304411. No spark of metal surface, its material commonly used copper, aluminum and other non-ferrous metal production. Misfire of nonmetal materials to the ground, the ground of the organic materials can be divided into not angry again, such as asphalt, wood, plastic, rubber, and laying, but due to the conductivity of these materials is poor, can with insulated positions, so adverse to guide go electrostatic, when use the material, must consider guide go electrostatic grounding device at the same time; Another for misfire inorganic material ground, is to use no spark cement sand, fine stone concrete, terrazzo, such as inorganic materials, aggregate can choose misfire materials such as limestone, marble, dolomite, but the stone in the broken with ball mill processing. To prevent possible into iron filings, in front of the ingredients should be absorb with stir bar magnet stones with steel scrap iron powder, and then ingredients test block, identified as not angry before formal production. To carefully, don't angry ground test must be conducted before the construction, a general method is to use on 15 cm in diameter of emery wheel handheld grinder, equivalent to about iron artifacts from 3 m high free fall impact the linear velocity of the ground, in a dark room or at night grinding block ignition experiment was carried out, such as do not produce sparks is qualified. When using misfire concrete production ground, frame materials should not use glass, aluminum or copper frame should be adopted.
