Emery Floor Construction Process and Main Items
Emery ground floor is the common name for domestic hardwearing and hardened floor. Foreign enterprises call it "ground hardener". The new type of ground building materials introduced by foreign companies in the 1990s is suitable for ground decoration needs in industrial sites, docks, parking lots, commercial stores, and logistics warehouses. With wear and compression resistance, reduce dust, hard surface, easy to clean, economical and durable. Because of its convenient construction, non-pollution, low cost, long service life and other characteristics, it has made an astonishing growth rate in cities with relatively developed coastal industries such as the Yangtze River Delta and the Pearl River Delta. Now it has become popular in China. The following describes the construction process and major issues of the emery floor . Emery Floor Basic Information The mineral alloy aggregate (corundum) ground hardener consists of a certain amount of mineral aggregate aggregate, special cement, other admixtures and admixtures, which can be used after opening the bag. It is evenly spread on the surface of the concrete that is to be set in the initial setting and processed by special means. So that it forms a whole with the concrete floor, and has high density and coloring of high-performance wearable ground. The essence of cement flooring is cement product. It is the product of high-grade cement mixed with different grades of quartz sand. Of course, it has the characteristics of cement products: the free Ca+ and Mg+ are continuously generated from the pores to cause the generation of dust; Hydration in the final water loss, resulting in a lot of hair pores, and thus resulting in not dense, so its strength, wear resistance are greatly reduced, because the thickness of silicon carbide is generally 3 to 5 mm, very easy to fall off, If you do not have a good time for cutting. After the thickness of this layer is worn out, the cement below will start to ash, so usually after one year of use, even if there is waxing maintenance, it will inevitably scratch and wear. Emery Flooring Material is a ready-mixed, on-site, dry-ground hardener. Mainly consists of high-strength cement, inorganic wear-resistant aggregate, pigment powder (cement color no), additives and other components. The aggregate is sand-like, with an average particle size of 1.5mm, which accounts for about 60% of the total; the cement is a treated high-grade cement. In addition to the cement color, there are various colors such as red, yellow, green, and gray. select. The hardener aggregate composition is natural ore. Department of rust-free non-metallic aggregate, the hardness of Moh's above 8 degrees. Except natural ore aggregates, the weight of other cements, pigments, etc. does not exceed 25% of the total weight. This product is directly applied to the surface of concrete or cement mortar in the initial setting stage. After being smoothed, it forms a hard, wear-resistant, dust-free and beautiful hardened floor. First, the scope of application: It is used on grounds where wear-resistance is required to reduce dust, such as warehouses, docks, factories, parking lots, maintenance workshops, workshops, and warehouse-style shopping malls. Second, the construction process 1. Base concrete pouring The concrete pumping process at the grassroots level shall be fully prepared to ensure continuous pouring, and concrete condensation time tests shall be conducted to know the time from the initial setting to the final settling of the concrete in advance and to make it suitable for the necessary process time for the construction of the corundum surface layer. When pouring the concrete, fill the concrete between the two channel steels with the embedded channel steel logo as the boundary, and vibrate and compact the concrete. Then use a scraper to lean against the channel steel to level the surface. After the concrete is in the no-flow state, remove and fix the concrete. Nuts, take away the channel steel, immediately filled with concrete tamping level, submitted to the surface construction team construction. 2. Diamond sand surface construction The corundum surface layer is a premixed product with high-strength, tight-grained aggregates and specially formulated additives. The construction is the initial set-up phase after the completion of freshly poured concrete. The product is divided into secondary spreads and then completed using specialized machinery operations. The formed diamond grit surface layer forms a whole with the concrete of the base layer, and has extremely high strength, hardness and no dusting characteristics. 3. Its main construction process is: 1) Remove the laitance, the first time fabric: The ground concrete should be sprayed with 2/3 of the prescribed amount of corundum before the initial setting of 5 to 60%. The disc grinder is used to compact the bristles so that the corundum penetrates into the concrete surface. 2) Detailed leveling, second cloth: After a certain period of time, the remaining 1/3 of the corundum will be sprinkled in a manner similar to that of the disc grinder and the metal file. 3) Mechanical boring operation: At least three times of blade-type sander polishing work shall be performed depending on the hardening of the concrete. 4) Surface detail polishing work: The surface finish is finally completed by mechanical boring or manual boring. 5) Maintenance: Apply curing agent curing according to weather conditions. 6) Expansion joint cutting and PU adhesive caulking. 7) Hand over waxing. Third, pay attention to matters The key to the success of the large-scale, high-standard, one-time molding of the silicon carbide flooring construction is the following: 1) Concrete coagulation time test must be conducted to select suitable concrete mix ratio and cement admixture. If the concrete is set too fast and the corundum surface cannot be constructed, a large amount of cement slurry will accumulate when the concrete is congealed and the corundum builds up, affecting the surface quality. 2) A reasonable concrete donor process must be established to ensure continuous casting and the speed of construction with the surface layer. 3) According to the requirements, reasonable surface materials must be selected and the materials must be strictly controlled. It is strictly forbidden to use silica sand instead of corundum to weaken the surface hardness. 4) Personnel with construction experience must choose special level control and surface construction to ensure quality. 5) It is necessary to strengthen the sense of protection of finished products, especially the finished product protection of colored silicon carbide flooring.
