Currently, along with the technical development of our country science, especially the quick development of electronics, information, defence industry, aviation Ang day, chemical engineering...etc., the static electricity endangers gradually and seriously. The static electricity endanger of comprehensive manage also is pay attention to by the international community day by day. The static electricity endanger of comprehensive manage is a system engineering, big body adoption following two paths: first pack through a craft, work, personnel, environment control etc. measure, prevent from or reduce an electrostatic creation possibly. The second, pass to moderate or the method for leak remove static electricity. In the aspects of constructing material, the static electricity leakiness material of local production have: anti-electrostatic anti-electrostatic floor of the rubber plank, PVC, anti-electrostatic dynamically tectonic plate etc.. Above material although each advantage, get at the certain scope application, again each save shortage, limit above product of further development and application. For example: the anti-electrostatic rubber be easily aging, wear away, easy Ran; the PVC anti-electrostatic floor piece glue kNot effect bad, easy leak out the Tan black powder; Anti-electrostatic movable floor inconstancy form, easy Ran, and around conduct electricity gum a conjunction not good, make anti-electrostatic function unsteady etc.. Because the above-mentioned oak Su is anti-electrostatic ware existence blemish, the personnel of science and technology begins to develop an anti-electrostatic water mill stone currently, some also took out a product. But the effect disregard think, they walked to a common mistake area, then chase anti-electrostatic material, mainly is the Tan black powder to directly add a person to the cement and water, because the Tan is black the specific weight be very small, and the affinity of the cement and water again bad, so distribute asymmetry. The anti-electrostatic whole function is bad, the strength be easiest low and start to wear away a dust, physically very difficult expansion applied. We provide a kind of anti-electrostatic function whole, consistency, stability, the good water mill stone of the machine strength now-anti-electrostatic water mill stone, the anti-electrostatic water mill stone ground adopts an anti-electrostatic stone residue, anti-electrostatic connect a ground of system, anti-electrostatic carry son and anti-electrostatic water mill stone a ground to become an integrity of have a special kind protection a technique, Compare in the anti-electrostatic movable floor of the domestic and the commonness, science and technology content Gao , technique level and technique difficulty not big, craft simple, easy operation, the ground canbecome to live at a time, the ground after start construction is neat, has no modifier, bears to whet, strong and tough, service life long, not easy breakage, build price low. Compared with the anti-electrostatic movable floor, the anti-electrostatic water mill stone ground didn't lower floor clean empty, raised engine room of can make use of high dimension, and ground service life long, not easy breakage, can consumedly save to maintain expenses. And the manufacturing method of water mill stone be simple and be easy to an expansion application. This kind of anti-electrostatic water mill stone mainly from is in advance constitute by the natural stone material crushed stones, cement, water of the Fu anti-electrostatic coating, make a method in, anticipate a stone first with the anti-electrostatic coating handle combine nature dry solid turn, then press production craft and Comparison of common water mill stone to fill with person's cement and water to mix, model, dub out, throw light etc. work preface. Adoption drive in advance the Fu make that product of anti-electrostatic the function whole, consistency, stability good, machine strength's etc. of the water mill stone is all very good, and for the incombustibility material, bear dirty, bear aging. That method is simple, can make into a plank material and used for noodles in the anti-electrostatic ground, wall noodles, pedestal. Can also sprinkle to build an anti-electrostatic water mill stone a ground on the scene, this product application is extensive. Since can be apply in the calculation engine room, distance to control engine room, can be apply in static electricity sensitive a dollar spare part and the whole machine production line again. Can also be apply in to anti-electrostatic have higher request, the machine strength request better fire work industry to produce a car and easy the Ran easily explodes place, database building...etc..This text is totally divided into five the parts carry on a researchChapter 1 is an introduction part. Mainly point out a domestic and international research a development present condition, this text draws up research contents.Chapter 2 anti-electrostatic water mill stone the technique principle of the ground .Join a certain comparison in now make the common water mill stone ground material the match the ratio of through the stone residue of anti-electrostatic processing(common water mill stone residue: Through the stone residue of anti-electrostatic processing=1:2)but the ground become, cover up to go in to plate zinc a flat iron in the anti-electrostatic water mill stone ground seek the even layer(bottom in seek an even layer a 10 mms) anti-electrostatic connect a ground of system, and at anti-electrostatic water mill stone noodles layer in the ground each 30 ms 2 spread to establish an anti-electrostatic copper to carry son, make anti-electrostatic stone residue, anti-electrostatic connect a ground of system,anti-electrostatic carry son to become with anti-electrostatic water mill stone ground an integrity of have a special kind protection a technique(static electricity protection, static electricity safety) of whole, treat to make an anti-electrostatic water mill stone a ground now solid after turning aridity, at temperature is-15 C the~55 Cs, relative humidity is 10~85%, system electric resistance is 5×104-1×109 Mu in Europe.Chapter 3 anti-electrostatic water mill stone concrete match ratio design. The cement should choose to use 32.5 above Huo sour brine mires, common Huo sour brine mire or the mineral residue Huo sour brine mire. The color and luster is fresh to have no caking of part agglomeration of not proper usage. The water mill stone noodles layer of white or shallow color. As far as possible use the white cement of same batch. Stone grain use strong and tough can whet of dolomite, marble etc. the rock process but become. The stone grain degree of hardness once wanted Gao not, the grain path shoulded not lead greatly, various stone grain press the species specification the color deposits respectively, can't mix. Pigment from decorated effect to say, have important position, should have color light, apply color dint, bear light and bear water. Color light for make, apply color dint consistent. Should choose same pigment of batch. The copper has to regulate an usage. Grass' ising sour is from the color crystal. The wax uses a floor wax.Through the match of the calculation concrete than(basis match ratio) is a cement: Common pebble: Through the anti-electrostatic processing pebble: Water=573.2:530.6:1061.2:235, namely cement: Common pebble: Through the anti-electrostatic processing pebble: Water=1:0.93:1.85:0.41.Chapter 4 makes an anti-electrostatic water mill stone ground construction a craft now. Want to want make the water mill stone noodles layer the construction attain anticipant effect. Have to strictly control a construction craft. Specially control the Comparison of dosage and stone grain of good cement syrup color powder. The water ash ratio is also the important factor which influences a water mill stone quality, under construction must sternly control .Moreover still need to arrange good construction work a preface, put on a stone grain, the syrup trims border after doing big noodles first.; Color first and deeply shallow behind, 1 kind after solidify, 1 kind after spread again. Press the construction ability certain spread stone grain syrup each time of but accumulate, in strength once was unlikely Gao Shi2 complete a beginning to whet. The noodles layer wipes two times of syrup at least while dub out and press construction procedure again to operate after protect. Only pass value and control of each wreath, then can satisfy the material, species, color of design request and go together with ratio, strength...etc. the provision of various index signs and construction norm.Chapter 5 conclusion and outlook. The anti-electrostatic water mill stone ground mainly expands to apply to have the technical equipments of the special kind protection to use building at the correspondence equipments engine room, calculator engine room...etc. and the electricity fire industrial production which used for an anti-electrostatic water mill stone surface electric resistance to the ground for one×104-1×s 107 Mu in Europe uses building. The anti-electrostatic water mill stone ground acted for with the traditional common water mill stone construction craft the cement ground up spreads anti-electrostatic movable floor, since satisfied equipments engine room to the technique request of the special kind protection, and then consumedly lowered engineering cost, raised the high dimension of engine room, can completely act for common and anti-electrostatic movable floor. Especially have to the engineering constructions, such as electronics, information defection industry and chemical engineering...etc. better of applied foreground and expansion value.
