Polish concrete, it is to point to the concrete surface formed after grinding tool burnish step by step and classics with chemical hardener common action. Builders use chemical hardener penetration natural pouring concrete, make its surface strength and density were stronger, and by mechanical grinding and polishing to improve the smoothness and the luminosity, so as to make the concrete floor and use performance and special decorative effect, suitable for commercial ground, such as restaurants, cafes, shops, schools, shopping malls office high-grade private garage, etc.
Advantages of polished concrete floor:
1, hard: gold concrete sealing curing agent treatment of the ground, mohs hardness will reach 9, Mohs hardness increased by 45.3%;
2, wear resistance: concrete sealing curing agent can be terrazzo in a variety of components curing into a hard entity to increase the hardness and density, the use of terrazzo ground concrete sealing curing agent after the ground curing, wear resistance will be increased to more than eight times
3, polished concrete floor dustproof; Ground concrete sealing curing agent and terrazzo concrete sealing curing agent effect contrast of silicate chemical reaction, in the concrete surface to form a dust-free, dense whole, permanent control of concrete dust precipitation from the surface gap.
4, skid: general concrete ground, salt and alkali components will precipitate from the surface, resulting in skid. But concrete sealing hardener ground is different, he forms a solid, dense whole on the surface of concrete, salt and alkali components will not precipitate from the surface.
5. Compressive strength: the compressive strength of concrete sealing curing agent floor is increased by 27.3% after treatment, and the flexural strength is increased by more than 3 times.
6, impermeability: concrete sealing curing polishing ground agent can effectively penetrate into terrazzo, and chemical reaction with gas, lock the pores inside, permanent sealing effect on the surface of concrete, can effectively inhibit water, oil and other surface pollution into concrete
7, weathering resistance; Ultraviolet ray and water spray have no adverse effect on the treated pattern, concrete sealing curing agent can effectively prevent the passage of fluoride ions, testing shows that fine treated ground, will not be affected by exposure to electromagnetic or water mist;
8, corrosion resistance; The ground treated by concrete sealing curing agent will greatly improve the corrosion resistance of concrete.
9, light; Concrete polishing process after grinding to remove concrete surface layer, will show the natural color of concrete tend to be more, the stone material of premixed concrete and specially or specialty aggregate (such as black pebble, granite, basalt or ore and waste rock) mix concrete, after ultra-fine grinding and polishing processing, can present a more design and color effect. In the finished stage of surface pouring, decorative aggregates such as shells, conch, glass fragments and even metal car parts are embedded into the surface. The polished effect is very artistic and helps to realize various creative ideas of designers.
Concrete floor can be polished by wet film or dry grinding method j, but because the dry polishing speed is faster, the operation is simpler, more environmentally friendly, so dry polishing is one of the most commonly used polishing methods in the industrial field. Wet polishing requires water to cool the emery grinder and clear the grinding chips on the machine. Because water acts as a lubricant to reduce friction, it can extend the life of the polisher. But the biggest disadvantage of wet polishing is that it produces a lot of mud. Dry polishing does not need to use water, and dry polishing using ground polishing machine is installed with dust collection device, can effectively absorb dust particles. Foreign advanced vacuum equipment usually has a three-stage filtration equipment and pulse blowback device, can effectively absorb dust particles.
