Next four weeks to confirm the vertical bracing to prevent inclined backfill. First backfill backfill debris removed before crushing and gravel backfill evacuate after the first pump stratified backfill backfill 500mm thick tamp tamp fill namely, electrostatic conductive material layer about 30mm thick 1000mm secondary backfill compaction at the second Fill in the secondary layer electrostatic conductive material about 30mm thickness 1500mm backfill three points three times two to three times tamp filled electrostatic conductive material layer about 30mm last backfill to grounding bisects two to three times the original ground level compacted fill the last replantation green. Trunk connection means connected to the indoor trunk from the ground in a line before making the soil less than 5 discount segment interior trunk to prevent sedimentation and bring stimulating impact on the soil should be used after a plastic pipe plus steel jacket jacket height of not less than 300mm height extending from the ground to the desired position along the wall to connect branch bolted copper wall from 1030mm 3000mm distance along the wall sheathing should lead to the indoor and outdoor walls firmly fixed in the building after the trunk. After the branch line connecting the ends of the grid along the ground lead foil on the wall in the trunk of the reserve 1030mm wound on the winding Route 2 laps wound should be close to the trunk to make close contact with common conductive filler mainly carbon based filler metals and metal oxides, complex inorganic fillers. (1) Carbon-based filler carbon-based filler include carbon black, graphite, carbon fibers and carbon nanotubes four categories H ". Garage floor paint black is decomposed by the hydrocarbon compounds obtained by the heat due to different manufacturing processes, structure and morphology of the carbon black will be very different, their electrical conductivity is different. In general, a high carbon black morphology (e.g., acetylene black), and their particle chains can form a network with the conductive member, the electrical conductivity is high; and low carbon black morphology, the lack of particle chains, conductive carbon black conductive paint used on the poor and other conductive products are often recoverable conductive channel black, furnace black lead, superconducting electric furnace black, special conductive furnace black. , acetylene black carbon black, although conductivity is not high, but to meet the requirements of anti-static, with excellent weather resistance, chemical resistance, and low cost, abundant source, such as the amount properly, affect the physical properties of the coating is not large, so black is widely used in anti-static coatings. black conductive filler to do the biggest drawback is itself black, add a large amount of products can only make a few simple dark gray, black, etc., it is difficult to modulate Other bright colors, so much has been used to make paint street]. layered structure of graphite determines its electrical conductivity, which is due to the crystal did not participate in the hybrid electronic relatively free of P, equivalent metal crystals Freedom Electronic Therefore graphite conductive filler is selected for Practice often mixed graphite and carbon black, or 174. 2006 Bayer cup. Full Bin environmentally friendly high power foot Rong # Tu mushroom technical discussions to make 2006 Fung j, month in State - functional paints a different electrical conductivity of carbon black mixed use, to meet different requirements by natural flake graphite intercalation, washing, drying, high temperature to obtain a porous puffed worm-like substance, called expanded graphite , also known as flexible graphite, graphite powder with the different conductive mechanism. expanded graphite worm is a worm-like nano-tubes, in itself form a good conductive path, it would be as a conductive filler, when its concentration reaches a worm can ask When each bite, the worm will be like a metal wire in general, thus having a good electrical conductivity. A few years ago there was the use of expanded graphite packing worm reported in the literature for preparing a conductive coating, such as Chen and other I "studied with expanded graphite fillers, conductive coating production of acrylic acid, the experimental data show that the coating has a very stable filler worm volume resistivity, with almost no change in the addition amount of the filler.
