Contact; 13701126040 Liu Xuan Before wear layer construction, the original concrete base silos and coal slot has finished construction of more than 28 days to reach a final hardening strength, in order to ensure the wear layer and the original concrete base bonding firm to form an organic whole, to take the following three processes necessary to prepare: primary treatment, the laying of steel mesh, brushing interface agent. 1 Primary treatment Primary treatment interface main attention to three points: ⑴ roughness, the rougher the grass roots, the greater the interfacial area, the greater the force, the ability to resist shear failure of the stronger, so the grassroots cutting hair. ⑵ soundness refers to the degree of the adhesive surface by the injury, the damage more light, the less internal defects, adhesive properties better, so if you want to base surface loose parts should be removed. ⑶ cleanliness, reduce impurities, helping improve the bonding strength. So, to use a pressure water rinse to clean the base surface, not a floating pulp, floating dust and mold release agents and other debris. 2 laying of steel mesh anti-friction layer in order to ensure the integrity of the concrete base, reducing the wear layer shrinkage caused by a large area of ??plaster, increasing constraints prevent the hollowing and cracks in the grass surface to be buried steel mesh. Concrete base drilling deep 70mm, aperture 12mm; anchoring with steel anchor material Ф6mm steel rod, steel rod buried depth 70mm, exposed 15 ~ 30mm (1/3 design wear layer thickness), the spacing between the steel rod 300mm; steel the top of the stick into the net with Ф6mm welding rod. The first three brushing interface agent 3.1 Construction 2 hours to fully wet the base surface, the floating dry construction. 3.2 special interface treatment agent and 42.5 ordinary portland cement, sand in a 1: 2: 1 mixture, stir well and set aside. The mixed slurry evenly brushing interface agent concrete foundation in a good surface treated, can not be missed 4 anti-abrasive brush stirred high-strength anti-abrasive can be mechanical stirring or manual stirring recommended compulsory mixer mechanical stirring can improve construction efficiency, and ensure adequate mixing evenly, better construction effect. Site water addition of 13.5% to 14% water mixing, the consistency is appropriate in order to fit construction, construction stirred position as close as possible to facilitate the continuous progress of the construction. Add water and stir until the completion of construction should be controlled within 40 minutes is appropriate, it should ensure that each stirring speed to match the amount of construction. 5 interface agent surface to be painted plaster finger when touch dry, use spatula to anti-abrasive and put it on the concrete surface, to press hard on the first layer of plaster. After each plaster thickness of not more than 20mm, when the wear layer design thick layer of plaster layer to be the first to reach the initial setting state, the next layer of plaster construction, construction to design anti-wear layer thickness. 6 calender according to climatic conditions, 1 to 2 hours after, anti-abrasive calender processing close to the initial setting. Calendering process is very important to reduce the surface roughness of the wear layer, the material is conducive to the smooth, non-blocking material. If the thickness of the larger construction, crack prone plastic, so in 1 to 2 hours after the first calender for a second calendering summer construction 7 conservation, should be within 4 hours after completion of construction, high-strength anti-abrasive First After coagulation stamped wet straw bags or rockwool watering conservation. Winter construction, the construction should be finished immediately covered by plastic film and stamped straw bags or rockwool and take insulation measures. Curing period of 7 days, conservation measures should comply with the relevant provisions of "reinforced concrete construction and acceptance of norms" in the Company's sales of high-strength grout material wear-resistant epoxy grouting material reinforced mortar factory Anchor plastic epoxy repair mortars, self-leveling (tile marble tiles) polymeric binder (adhesive plaster cracking brickwork) mortar grouting resin glue stick steel processor from sand mortar Wang mortar cracking agent expanders rust inhibitor colloidal crystal lignocellulosic water putty hook Dry joints agent interface agent interested, please call! ! !
