application analysis of microsilica in epoxy floor-pg电玩城

  microsilica is a neutral inorganic filler with very stable physical and chemical properties. it does not contain crystal water and does not participate in the curing reaction, and does not affect the reaction mechanism. it has good wettability to various types of resins, good adsorption performance, easy mixing, and no agglomeration. the microsilica has reasonable particle size distribution, strong compactness, high hardness and good wear resistance, which can greatly improve the tensile, compressive, impact strength and wear resistance of the cured product, and the anti-wearing ability can be improved by 0.5-2.5. 

  times. before the construction of the epoxy floor, the construction preparation should be completed first. the preparation contents include epoxy floor paint materials and construction equipment. among them, epoxy floor paint materials need epoxy primer, epoxy middle coat, epoxy top coat, micro silicon powder, putty powder, quartz sand, thinner; construction equipment needs grinding machine, grinding machine, milling machine, shot blasting equipment, vacuum cleaner, broom, mixer, weighing, barrel, drum, floor paint (flat, round) trowel, flat bottom scraper. 

  secondly, the epoxy floor should be treated before the epoxy floor construction, mainly to expose the damaged, sanded, loose, weakly viscous, cracked, and empty parts, and the floating mortar and old epoxy cement agglomerates and other smoothing, and clean the surface of the surface of the floating ash, pollutants and other garbage, and then you can start the epoxy floor construction work. 

  the microsilica manufacturer infiltrates the soil layer by injecting the slurry into the pores of the granular soil under the pressure (ie, no hydraulic splitting) that is insufficient to destroy the formation structure, thereby replacing and discharging the air and water therein. . the osmotic grouting slurry generally spreads evenly into the gap between the sand and the soil layer particles, and after cementing, the purpose of enhancing the strength and impermeability of the sand body is achieved. with the development of china's cities, the deep foundation pit engineering and urban underground railway engineering have increased year by year, and the underground engineering of most cities is under the geological conditions of fine sand, medium sand, coarse sand, gravel sand, and the surrounding rock is loose and weak, and the self-stability is self-stabilizing. 

  poor, it is easy to collapse when excavating. therefore, grouting reinforcement is generally performed before excavation. at present, cement-water glass slurry (with water) or cement slurry (anhydrous) is often used for grouting in sandy formations, but only when the formation is coarser or higher, cement slurry can be injected, and in the formation is medium-grain or above. at the time, the cement slurry and the cement-water glass slurry can be injected. if the particles are smaller than the medium sand, the cement slurry or even the cement-water glass slurry is difficult to inject.
