Do you know the epoxy flooring system structure? The structure of floor coating can be divided into three parts from bottom to top: primer, floating coating and surface coating. And do you know what's the function of them? Primer of Epoxy Flooring System Structure: The primer requires good permeability, no pigment filler, and good alkali resistance. Its functions are as follows: 1. Close the concrete pores to eliminate the tidal bulge problem caused by,and enhance moisture-proof fixing effect. 2. Strengthen the bonding strength of the base surface. 3. Increase the adhesion between the base layer and each layer. Floating Coating: The middle coating is mainly composed of film-forming materials and aggregates that improve mechanical properties, such as quartz sand. Its functions are as follows: 1. Effectively fill the surface voids of the concrete base and improve the strength of the floor system. 2. Make the surface of the floor smooth and easy to paint. The thickness of the intermediate coating is controlled at 0.5-3mm. Surface Coating: The topcoat is direct contact with environment and air. The aesthetic effect of the epoxy floor also depends on the surface coating. For topcoats, it is generally required to have good abrasion resistance and mechanical strength,so that it can resist the external shocks and the effects of ground thermal expansion and contraction.In addition, the surface decoration effect of topcoat is very good, if necessary, it also has anti-slip and corrosion resistance.

High Tech Grinding Concrete Floor Polishing System is a polished concrete floor that go through equipment grinding,abrasive polishing and chemical reaction. It works with a floor grinder to dry-grind floor surface,and creates a high brightness,high hardness and high density concrete floor. Why we choose a dry grinding method to achive a polished concrete floor? Dry grinding is more environmentally friendly. Sewage and mud produced by wet grinding are more troublesome to clean up. If it is discharged directly into the sewer, it will polute the environment,and when they dry up may cause blockages. The dust produced by dry grinding is not good for human health, but it can be cleaned up by a industrial vacuum cleaner to achieve dust-free floor grinding. What are the benefits of dry grinding for concrete floor construction? ▶Dry grinding is more secure and has strong visual recognition ability. Even if there is dust, it only needs to be cleaned. It is more convenient to observe the floor grinding effect.However the sewage and mud produced by the wet grinding will hinder the workers' observation of grinding effect. ▶Dry grinding is more efficient and reduces labor costs.  By connecting a vacuum to a floor grinding machine when dry grinding can create dust-free construction working environment.It will save the trouble of cleaning slurry,which produced by wet grinding,and dry grinding artificial dust removal,which is more effiecient and less manpower. High Tech Grinding Concrete Floor Polishing System adopts dry grinding to cure concrete floor, so as to achieve dust-free grinding of the floor, improve the floor construction efficiency, reduce labor intensity, and make polished concrete effect better.

The six major concrete repairing ways of High Tech Grinding system include grinding, cutting, drilling, batching, polymer mortar, and affusion.And among which there is a special repair process for the hollow floor---affusion method. How to use affusion way to repair the empty drum concrete? The grouting nozzle is buried in the empty drum position for filling, and the hollow drum position is filled to ensure the integrity of the concrete. Repair process: ★ Preparation before construction 1. Confirm the empty drum position that needs to be treated. 2. Drilling at the empty drum position, surface cleaning, and embedding the slurry nozzle. ★ Chemical grouting 3. Grouting is carried out after the grouting nozzle is installed. The grouting pressure and amount are determined according to the specific conditions of the empty drum part. 4.After preparing the grouting resin,pour it into the container of the grouting machine. 5. Fill the grout resin into the empty drum position with a high-pressure grouting machine, while confirm the filling is full, close the valve immediately. When grouting, it is necessary to prevent the grouting liquid from overflowing from other holes and causing waste. Confirm that the grouting is completed and remove the implement. 6. After 48 hours, the resin was initially coagulated; after 7 days of dry curing, it can be used normally. The infusion method uses grouting to repair empty drums, and the time is fast, and the base layer will not be damaged, especially for the underground garage, factory building, etc.,  the construction process does not affect the owner's use, which is a convenient way.
