FYT-1 bridge special waterproof coating

FYT-1 bridge special waterproof coating Description: FYT-1 improved waterproof coating (HC-201), is a polymer composite material, is a key state science and technology promotion projects, organized by the state authorities of experts reached similar products leading level. Products by the Ministry of Transportation Highway Engineering Test Center tests, all the technical indicators are in line with JT / T575-2005 standards; conform JTT041-2000 (highway bridges and culverts construction technology specifications), using special domestic or imported oil bitumen asphalt as the main raw material, with each surfactants and a variety of chemical additives, SBS thermoplastic rubber auxiliary materials, increased doses of doped polymer resin modified to produce a new type of composite waterproof coating. FYT-2 polymer deck waterproof coating (HC-202) may be used alone, it can also be modified using FYT-1 waterproof coating compound for bridge deck waterproofing to prevent leakage due to the concrete deck reinforcement corrosion caused by increase the life of the bridge, FYT-1 and the performance by the Ministry of Construction FYT-2 assessment of the leading domestic level. Product Features: 1, the construction process is simple, construction machinery available spray can also be manually brushing, drying, short construction period. 2, the waterproof layer are cheap, generally only brushing three times to achieve the waterproof effect. 3, waterproof layer and the base layer, waterproof layer and the upper asphalt concrete bonding firm. Technical Specifications: ◆ Main technical indicators (based on JT / T 535-2004 and JC / T975-2005 "bridge aqueous bitumen-based waterproof coating" standards) Application: For highway bridges, urban overpass and bridges and culverts and other water projects. Construction, transportation and storage: 1, construction tools ready: pre-construction should be ready spices barrel, spraying machinery or special bristle brush. 2, the primary requirements: bridge deck, beams concrete strength of designing the label, the surface may not have loose floating pulp, peel, hollowing and severe cracking phenomenon. Surface flatness should meet the regulatory requirements bridges, vertical drains catchy grassroots level should be lower than the elevation, the outlet must be installed with the grass roots firmly, without any loosening. 3, the substrate should be clean, dry and free of water. 4. Primary treatment: the base surface may not have dust, floating dust, impurities, grease, etc., do waterproof layer before available air compressor, water, oil and other surface treatment to clean, if concrete, mortar and other debris in hard knot and should be polished off. 5, waterproof layer construction with three Tu step :( example) 1) should be bottled before brushing paint and mix well. 2) a large area with a small brush before brushing to the mouth of the drain twice to do paint, brushing against the female corner portion strengthen waterproof coating three times, and then a large area of ??brush paint the first pass. 3) The first pass coating material can be painted a second time after a hard work. 4) the second time table dry brushing paint coating the third time. 6, the amount of paint: 0.5-1.0kg / m, film thickness 0.6 ~ 1.3.mm, spraying 0.3 kg / m. 7, the construction temperature at 0 to 35 degrees Celsius is appropriate, rainy day, not construction freeze. 8, packaging products in covered metal pail, barrel weight of 200kg, 50kg 9, transportation: The product is non-flammable, non-toxic, according to general modes of transport. 10. Storage: The product storage period of six months, should be stored at 0 degrees Celsius warehouse, the summer should avoid sun exposure.
