I. Introduction "Bolong" cementitious capillary crystalline waterproofing materials are imported from abroad active chemical products, commonly known as masterbatch, with Portland cement, silica sand and other components of gray powdery inorganic material, waterproof principle is: this kind of material specific chemicals inherent in the use of cement concrete chemical properties and porous to water as a carrier, with penetration, and concrete pores and capillary transport. c achieve permanent waterproof, moisture and protection of reinforced concrete structural strength enhancement. Second, the product features a long-term bear strong pressure, at least able to withstand water pressure 1.2Mpa head. 2, the penetration depth 30CM above. 3, self-healing capabilities. There is a unique catalyst, water is activated to produce new crystals, tiny cracks in the concrete structure and therefore a number of years when there is water infiltration, will produce new crystal water blocked, this self-repair capability is unique. 4, reinforced concrete strength, chemical resistant, reinforced protection. 5, non-toxic, pollution-free, safe and environmentally friendly, water can be used for life concrete structures. 6, the construction of the base surface is not waterproof layer as a general requirement flat, dry, on the contrary requires the base surface roughness, moisture better results. 7, the construction method is simple, low construction cost, after coating solidified, afraid of a collision, puncture resistance tear, so do not need to add fill to install reinforced protective layer, reduce project cost. 8, the surface may be the construction of cement mortar, lime plaster, epoxy coating, and good bonding effect. Third, waterproof plugging construction product uses grassroots waterproof construction of concrete structures, structural cracks, seepage points, holes, subway stations, underground continuous wall, tunnels, bridges, reservoirs, sewage treatment pond and plugging construction, industrial and civil buildings basement, bathroom, pool water plugging. Fourth, the main technical indicators: JC / T894-2001 Item Index Ⅰ type Ⅱ type solid content,% ≥ 65 65 dry dry time schedule, h ≤ 4 drying time, h ≤ 8 Tensile strength (no treatment), Mpa ≥ 1.2 1.8 Elongation at break (no treatment),% ≥ 200 80 Low temperature flexibility, (∮10㎜ stick) -10 ℃ no cracks - no water permeability (0.3 Mpa, 30min) impermeable moisture impervious base surface bond strength, Mpa ≥ 0.5 1.0 impermeability (back surface), Mpa ≥ - 0.6 V. construction points a clean-base surface, the base surface should be rough and clean. The base surface water soaked, but not out of water, the Blohm cementitious capillary crystalline waterproofing coating: water = 1: 0.25-0.3 (weight ratio) even reconcile with nylon brush tuned rubber brush to evenly waterproof base surface, generally brushing twice per square materials 1-1.2Kg (thickness 0.8MM). 2 brushing interval of less than 24 hours, such as when you first pass the initial setting still on the wet state, brushing the second time better, if too dry, water should be sprayed wet, to reconcile the plastic material to be used within 30 minutes , plastic materials can not add water when there thickens, stir frequently only to be uniform when brushing, punch can not have white or deposition. After four coating dry state, starting with mist spray water conservation, 2-3 times a day for 2-3 days, to prevent premature drying coating. 5 construction common coating methods are: brushing, dry sprinkle method, a spray coating method. VI Notes hot weather outdoor construction recommendations for construction sooner or later, to prevent premature drying coatings affect infiltration, surface coating of cement-based materials using when you want to continue with the work after 24 hours, such as backfill, seven days can not backfill dry soil to prevent it from absorbing into the coating. 48 hours of curing period, waterproof rain, frost, exposure and below 5 degrees temperature, open-air construction covered with a wet bag tide is better, but to avoid stagnant water, must be set up when using plastic film to protect and ensure the coating. " breathing "ventilation. Seven, packaging and storage: Packaging: 25 kg / barrel; 25 kg / bag. Storage: This product should be placed in a cool, dry place, avoid moisture. Shelf life: from the date of manufacture, unopened product shelf life of 12 months.
