How do you stick carbon fabric?
6, maintenance(1) after sticking the carbon fiber cloth, it is necessary to conserve 24h naturally to reach initial curing, and ensure that the curing period is free from interference(2) before each process, the resin should be covered with plastic film before it is cured so as to prevent sand or rain from attacking(3) when the temperature of the resin curing is reduced to less than 5 degrees, low temperature curing resin can be adopted, or effective heating measures can be adopted(4) CFRP after natural curing required to meet the design strength of time: the average temperature is 10 DEG C, 2 weeks; the average temperature is 10 degrees centigrade above 20 DEG C, 1 to 2 weeks; the average temperature is higher than 20 degrees in 1 weeks. During this period should be to prevent the patch part by the hard impact.7. PaintingThe coating shall be done after the initial curing of the resin and shall comply with the relevant standards and construction requirements for the coating used
3. Apply the base resin(1) the main agent and curing agent base resin according to the provisions of the proportion accurate weighing were put into the container, use a blender to mix uniformly. A harmonic volume should be in use within the time spent more than can be used as the standard, time cannot be used.(2) apply the base coat evenly with a roller brush(3) refers to the drying time, due to different temperatures, generally between 3H to 1D changes(4) after the curing of the base coat, when the surface of the component has a condensation bulge, it should be polished with sandpaper. If the surface of the concrete is exposed after polishing, the bottom coating shall be applied again4, the incomplete repair of the surface of the componentThe surface depressions (honeycomb pits, holes, etc.) using epoxy putty to fill, to repair the surface. (the poor, camber angle etc.) to be filled with epoxy putty, so smooth.
1 、 construction tools and equipmentThe main equipment includes cutting machine, angle grinder and roller brush2, concrete substrate treatment(1) remove the damaged parts and damaged parts of the concrete parts and reach the compacted parts(2) check whether exposed steel bars are rusted or not. If there is rust, the necessary treatment should be carried out(3) repair the damaged part of the component through the chisel, the cleaning and the exposed ribs, and then use the epoxy mortar, which is higher than the strength of the original component concrete, to repair and restore to the surface(4) crack repair. Cracks with a width of less than 0.20mm shall be coated with epoxy resin and sealed. Cracks greater than or equal to 0.20mm shall be sewed with epoxy resin(5) to the designated location, scope of patch repair and reinforcement of ink, according to the design requirements.(6) burnish the surface of the member (the connecting part of the concrete component, the difference of the section of the template), and make sure that the repaired section is as smooth as possible(7) the angular position, with grinder. Rounding radius should be larger than 30mm, the minimum of not less than 20mm.
