What should be paid attention to in Shenzhen floor paint project?
A, concrete strength must be greater than or equal to ≥C25. It contains more than 350kg/m3 of ordinary silicate. Cement and water-cement ratio < 0.45; Second, the leveling layer must be made of fine stone concrete with a thickness of not less than 50mm( 1). Because the construction of wear-resistant materials and the pouring of cement floor are carried out almost at the same time, in order to ensure the construction quality and progress of wear-resistant layer, the cooperation of mixed pouring should be done well; (2) For the formwork, it shall be flat and firm, the formwork shall be 6m, and the release agent shall be coated. The elevation of the formwork shall be detected at any time with a level meter, and the deviation shall be adjusted in time; (3) The concrete strength is not less than C25, and the water-cement ratio is as small as possible; (4) Use plug-in vibrator and plate vibrator to operate, use a level gauge to detect the level of the template after vibrating, and adjust the deviation parts; ⑤ Press repeatedly with a heavy long steel roller (the steel roller is wider than the template), and keep the steel mold clean, so that the ground is flat, and steel rollers cannot be used for operation. ⑤ Use a scraper to level off the site with severe bleeding, and use a rubber tube for bleeding; ⑦ It is best to wait until the wear-resistant surface is finished the next day, and the expansion joint will be cut by the building on the third day; ⑧ During Party B's construction, cross construction is not arranged, and Party A is responsible for protecting and maintaining the constructed ground of the other party, and Party A provides water and electricity; The products of cement base surface require that the cement base surface should be solid, firm and free from shell formation, so as to prevent mortar from shell formation. The concrete layer is best poured together with the mortar leveling layer. If the concrete layer is compacted first, the thickness of mortar layer should be not less than 4cm, and the forklift lane should be thicker. 2. It is required that the surface has no sand, good hardness and no cement pulverization. Requirement a, high quality cement. B, new cement mortar layer should be fully maintained. 3. The cement base surface is smooth, without unevenness, honeycomb pits and cement bumps. 4. The flatness of the ground is required to be no greater than the thickness required by the paint (leveled with 3m feet); 5. The surface is dry, the water content is less than 6, and the ground should be kept dry and free of oil pollution. Remember not to wash or mop the cement floor with water five days before construction. 1. The mechanical performance requirements mainly include the following three aspects: 1. Wear resistance: what kind of transportation will the floor walk? 2. Compression resistance: How much load will the floor bear when it is used? 3. Impact resistance: Will the impact force cause the floor surface to peel off? Second, the chemical performance requirements mainly consider the following two aspects: 1. Acid and alkali resistance: the type and concentration of corrosive chemicals when used. 2. Solvent resistance: the type of solvent used and the contact time. Third, the position of the floor depends on whether the floor is underground or above ground. Is it necessary to determine whether it needs moisture-proof treatment or choose a special moisture-proof floor? Four. Status of base surface 1. Strength of base course: compressive strength ≥20Mpa is generally required. 2. Smoothness: Is it necessary to repair with epoxy mortar? 5. Aesthetic requirements 1. Color requirements: Is it necessary to divide the area by color? 2. Brightness requirements: choose matte or bright color? 3. flatness requirements: is there any requirement for the flatness of the floor? Safety requirements of intransitive verbs If the floor is in an oily environment or on a slope, you need to choose a non-slip floor. 1. Environmental protection requirements for epoxy floor paint construction: a. Moisture content of base surface: non-aqueous epoxy floor cannot be constructed when it is above 6%; B, air humidity: more than 85%, should stop construction; C, construction temperature: below 5℃, special formula should be selected. 2. Maintenance of epoxy floor paint: epoxy floor paint is a high-value, high-quality and demanding product, which needs careful maintenance. Proper use can keep the floor as new and prolong its service life. The measures are as follows: ① Anyone who enters the workshop needs to change shoes (to avoid entering the workshop with mud and sand and scratching the floor); ② All hardware must be wrapped in soft plastic or rubber to avoid scratching the ground during use; (3) when dragging the tray, the tray should be completely off the ground. When turning, pay special attention to the tray angle not to scratch the ground; (4) When cleaning the floor, you need to use a soft mop or a wet and dry vacuum cleaner, and then clean it with water or detergent, but pay attention to the slippery floor; ⑤ If it is worn or scratched due to long-term use, it can be repaired locally in a small area. If the area is large, it is recommended to roll coating or trowel coating again. Design performance consideration of floor paint 1. Service performance requirements: (1), abrasion resistance (3), impact resistance (4), hardness (5), adhesion (6), dustproof performance (7), cleanliness (8) and antistatic performance requirements 2. Appearance requirements: (65438+) Building foundation and environmental requirements: (1), the ground floor or underground warehouse on the first floor should be designed with waterproof and moisture-proof treatment (2), concrete strength ≥C25, C30 standard effect is better (3), the surface smoothness of foundation concrete is 2m feet ≤ 3mm, and the performance of epoxy floor paint is decomposed. 1. Scope of application: used in general appliances, electronics, machinery, food, medicine, etc. It can also be used in schools, libraries, indoor parking lots, cable exhibition halls and other places. Second, performance characteristics: (1), dustproof, wear-resistant, pressure-resistant, waterproof (2), matte, bright, semi-dumb, anti-skid effect (3), low cost, easy cleaning, convenient maintenance (3), coating thickness and service life reference: service life is about 6 years (4), technical parameter list: epoxy anticorrosive topcoat. 1. The paint film is hard; 2, 2, excellent drying performance; 2, 3, high adhesion, good three-proof performance and good wear resistance. 3. Uses Epoxy anticorrosive topcoat is widely used for steel structure anticorrosive topcoat in various acid, alkali and salt environments, as well as anticorrosion, dustproof, mildew-proof and bacteria-proof of various floors, such as GMP pharmaceutical factory, electronics factory, food processing factory, textile factory, paper mill, hospital operating room and laboratory. 4. Main technical indicators of paint film: various colors; The paint film is smooth and flat. Adhesion (1mm) grade: ≤ 1 viscosity (25 c): 400 200 CPS impact resistance KGNan: ≥ 70 drying time h: surface drying ≤4h, hard work ≤24h alkali resistance, 30%NaOH, 48h: good pencil hardness ≥2H acid resistance. 48h: good wear resistance, 500g, 1000r, g: ≤ 0.2 ratio: main agent: hardener = 4: 1 bending test: ≤ 1mm water resistance for 30 days: no foaming.
