Chongqing hardened cement floor construction - Chongqing professional ground handling!

Cement floor paint is mainly used for concrete or mortar ground protection. And to provide a clean and beautiful concrete, corrosion, wear, decorated on the ground to play a protective role. Since more from Portland cement concrete mix sets of various sizes material after mixing with water condensed by hydration. Therefore make concrete inherent porosity and brittleness, leading to its relatively poor surface abrasion resistance, easy to wear, whether it is people walking or rolling of the vehicle, a lot of dust on the cement floor of frequent friction, in addition to affecting the production clean and beautiful plant, but also affect the normal industrial production. So cement floor first function is carrying traffic, concrete floor paint must have sufficient compressive strength and hardness, resistant to strong acid, wear, pressure, impact resistance, mildew, waterproof, dustproof, slip to and other characteristics, bright colors and diverse, easy to clean and a series of functions. 1 Scope of the substrate surface for concrete, wood, terrazzo, steel, etc. for sealer. Common ground floor with an ordinary primer XHDB001 type, anti-static floor anti-static primer XHDB001C type. 2 Main features ① permeability, excellent sealing ability, can improve the strength of the substrate. ② with excellent adhesion to the substrate. ③ coating alkali, excellent acid, water resistance, and the surface layer support and good. ④ can brush, roller, construction superior performance. 3 key indicators No Item Index 1 Appearance Brown transparent liquid 2 theoretical solids content (%) 32 ± 2 3 drying time (25 ± 1 ℃, relative humidity of 65 ± 5%, h) is dry <2 hard work <244 Adhesion ( The grid method, class) ≤1 5 impact resistance (kg.cm) 50 6 Water resistance (distilled water) for one year, unchanged 7 salt water (3%, 25 ℃) 1-year, unchanged in 8 resistance to oil resistance (45 # oil) three months, unchanged in 9 alkali resistance (10% NaOH) 56d, no change in the acid resistance of 10 (10% H2S04) 56d, no change in 4 construction method 4.1 method of preparation before use and stir Group A even, according to Group A: B min = 4: 1 ratio (weight ratio) preparation, aging 10 to 20 minutes after the stir, the construction used within four hours. 4.2 Construction conditions: concrete maintenance shall be more than 28 days, the substrate moisture content ≤8%, relative humidity ≤85%, construction temperature ≥5 ℃, coating interval of 12 ~ 24h. 4.3 application viscosity requirements: special thinner diluted with peaceful licensing qs to a viscosity of 12 ~ 16s (Tu -4 cups) when you can. 4.4 Prime handling requirements: The floor sander or sandblasting machine will loose layer floor, the cement stains, lime film foreign matter is removed and the unevenness of the ground level, the floor space dedicated cleaner clean. 4.5 In order to maintain the effect of the final cured coating and cause the coating dries, during construction and after construction is completed, should be kept well ventilated. 4.6 Theory of consumption: the painting environment without considering the actual construction time, the surface condition of the impact with the ground floor structure, construction of surface area of ??the coating thickness ≤0.1mm, general paint consumption 80 ~ 120g / m. 4.7 Construction Method: For the full depth of the primer to the substrate, increasing adhesion, preferably by roller coating methods. 5 5.1 Construction Safety requirements must avoid breathing vapors, eyes, skin contact with this product may not; required to maintain adequate ventilation during construction 5.2; 5.3 away from sparks and fire, its packaging have been opened, should be used as soon as possible; 5.4 note on the package security tags. 6 Packaging 6.1 primer used iron sealed package or plastic barrel, net weight 15kg, barrel curing agent NW 15kg, barrel diluent net 15kg. 6.2 Storage and transport: is flammable, keep away from fire and stored in a cool dry ventilated place, avoid collision, is strictly prohibited contact with water. 6.3 is valid for six months, more than valid, the re-test can still be using.
