Mpc a comprehensive supply of high elastic waterproof coating type material, easy to use, inexpensive

BMP is a one-component black viscous liquid, it will be the road (Bridge) group and a road (bridge) face fused together to form a high elastoplastic load, shear and waterproof overall, thus greatly improving road performance, extended Bridge especially steep curve overloaded pavement life. 2. BMP solvent infiltration mechanism (1) BMP containing permeable material, such permeable material can penetrate into the concrete pores 3mm-5mm depth, not only to repair the concrete after curing micro surface defects, can also clog the capillary water seepage hole , play a good waterproof effect; penetration while forming nail effect, firmly adhere to the concrete surface layer, can effectively prevent the waterproof layer of skin, delamination, and not susceptible to construction vehicles and paving equipment damage. (2) the role of waterproof bonding layer initial reaction curing cured at a high temperature (above 100 ℃) of asphalt concrete action will have a slightly melt distribution at large rolling action aggregate particles are embedded waterproof adhesive layer to form a uniform shear key distribution; elastoplastic waterproof adhesive layer after cooling generated to further improve cohesion, adhesion and shear strength while achieving 1.0Mpa above, the surface layer of asphalt concrete and cement concrete underlayer perfect combination to force a whole. 3. BMP main advantages (1) high permeability BMP after construction, wherein the reaction of the active material can easily penetrate into the pores of the concrete, the curing reaction to generate clogging, and therefore formed a solid concrete nails effect, not only to repair minor defects cement concrete, play a very good waterproof effect, but also for firm adhesion of asphalt concrete ready; (2) no water BMP completely free of water, avoid early water damage caused by emulsified asphalt-based materials risks, which generates elastic-plastic waterproof body, avoid waterproof layer peeling, delamination, hot asphalt pavement construction process will not be punctured and aggregate equipment, to ensure that the pavement waterproof bonding effect before and after implementation, effective against Water damage caused by road squeeze pulp, network crack, loose and pit Taipa; (3) was firmly stuck between the fresh concrete and asphalt concrete, bond and shear strength of BMP can produce up to 1.0MPa or more, to prevent overloading surface delamination, bed and hold bags and other diseases caused by the generation of vehicle, to ensure the integrity of the road surface, thus greatly improving road performance, extend the life of bridge, especially on steep slopes, curves and bridges and tunnels and other stress load larger roads; ( 4) Easy construction BMP artificial roller coating or spraying construction machinery, construction convenient, fast; you can start coating 4 to 8 hours after the completion of asphalt concrete, unlike other waterproof material long maintenance period, resulting in delayed progress of the project; (5) Flame Retardant BMP and other BRIDGES different waterproof material, both safety and environmental protection, have excellent flame retardant properties, especially for bridges and tunnels for load and safety requirements of demanding construction environment! 4. BMP uses (1) Scope: Waterproof bond between asphalt concrete layer and the interface between the other; part of the construction of water works; (2) Special Application: its superior performance is ideal for steep slope and curve road bridges and tunnels and other stress load is large, especially in a thin layer of road pavement stress concentration, such as: pavement, urban roads "white with black" rubber asphalt roads, excellent results. Second, the technical indicators technical indicators of BMP BMP has been completely beyond the "bridge with a waterproof coating" (JC / T 975-2005), and other building materials industry standard specifications: Table Specifications Item Index Test 1 BMP's The method of solid content ≧ 45% reference JC / T 975-2005 extension of ≧ 6.5mm GB / T 16777-2008 elongation% ≧ 800 GB / T 16777-2008 low temperature flexibility, -20 ℃ ± 2 ℃ no crack GB / T 16777-2008 bond strength, 25 ℃ ≧ 1.0MPa reference JC / T 975-2005 shear strength, 25 ℃ ≧ 1.0MPa reference JC / T 975-2005 dry (25 ℃) surface dry ≦ 2h GB / T 16777 -2008 pragmatic ≦ 4h GB / T 16777-2008 impermeability, 0.3 MPa 30min impermeable GB / T 16777-2008 heat resistance of 160 ℃, no flow and plain JC / T 975-2005 ignition ≧ 60 ℃ reference JC / T 975-2005 after hot rolling impermeability 0.7MPa, 30min impervious JC / T 975-2005 Note: bonding, shear strength test fresh concrete and dense-graded bond shear strength between asphalt concrete . Three, BMP Construction Technology Introduction 1. amount: 0.4Kg / m, the specific amount to be based on the base surface treatment conditions. 2. BMP construction process 2.1 Pre-construction base surface treatment: shot blasting sand blasting is recommended, requires the base surface dry and clean, not a loose, peel, and severely hollowing cracking; Treatment for difficult clean surface, The solvent can be used to clear or water, then dried hair dryer purge. 2.2 Construction process: (1) before coating BMP artificial construction, must first slight stirring for 2 to 3 minutes, making it easy to apply evenly; the operator with a roller, which is evenly coated and full coverage of treated concrete or qualified Other base surface, not leak brush. (2) mechanical hand-held spray gun construction can be manually by an operator hand-held spray gun, spray evenly; also can be intelligent asphalt distributor were spraying, but the amount should be strictly controlled spraying, be sure even paved, can be manually using a roller Trapping. 2.3 Construction Notes (1) The product construction temperature range of 0 ~ 50 ℃, rain, snow and windy weather can not be open-air construction; (2) Although the product flame retardant, but construction still prohibited fireworks; tunnel construction must be well ventilated and the implementation of two hours shifts; to be used for eyes (3) Construction of protection, if splashed into the eyes must immediately dipped wipe with a clean towel after washing with water, and consult a physician; (4) before spraying machinery construction, must stir ; construction interval of two hours or shut down after the pipe should be promptly cleaned using a solvent, in order to avoid equipment plugging on the next use. Four, BMP packaging and storage 1. Package: 20Kg / barrel, 200Kg / barrel; 2. Transport, Storage: ventilated, cool and smooth place sealed storage, to avoid an open-air, fire and sun exposure to avoid packing deformation leakage; 3 Save time: Valid 18 months.
