BMP-3 road and bridge waterproof coating factory where the brand is good

BMP-3 BMP Bridge is a one-component waterproof coating 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, thereby a substantial increase in road performance and extend the bridge particularly steep curve overloaded pavement life. 2. BMP Mechanism (1) solvent penetration of permeable material containing ??????? BMP, these permeable material can penetrate into the concrete pores 3mm-5mm depth, not only to repair after curing concrete surface micro-defects You can also plug 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 skin from the waterproof layer, delamination, and not susceptible to construction vehicles and Paving equipment damage. (2) the initial curing reaction curing effect ??????? waterproof adhesive layer at high temperatures (above 100 ℃) of asphalt concrete action will have a slightly melt distribution at large rolling action aggregate particles are embedded waterproof the adhesive layer to form a uniform distribution of shear key; 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 integrally combined into a force. After 3. BMP main advantages (1) high permeability ???????? BMP construction, wherein the reaction of the active material can easily penetrate into the pores of the concrete, the curing reaction to produce clogging, and thus cement the formation of a solid concrete nail 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, avoiding the risk of early water damage caused by emulsified asphalt-based material, which generates elastic-plastic waterproof body to prevent skin from the waterproof layer, delamination, hot asphalt paving process will not be construction equipment and aggregate thorn break, 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 in the fresh concrete ???????? between asphalt and concrete, bond and shear strength of BMP can produce up to 1.0MPa or more to prevent delamination overloaded road vehicles brought lapse and pro packages and other diseases produced to ensure the integrity of the road surface, resulting in improved road life performance, longer bridge especially steep slopes, curves and bridges and tunnels and other stress load larger roads; (4) the construction and easy ??????? BMP artificial roller coating or spraying construction machinery, construction convenient,? fast; after coating is completed 4 to 8 hours to begin construction of asphalt concrete, unlike other waterproof material long maintenance period, resulting in delayed progress of the project; (5) Flame Retardant ???????? BMP and other channels Different bridge waterproof material, both safety and environmental protection, but also excellent flame retardant properties, especially for bridges and tunnels to load and secure 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 ?? BMP BMP has been completely beyond the "bridge with a waterproof coating" (JC / T 975-2005), and other building materials industry standard specifications: Table 1 BMP technical indicators Item Index Test Method 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 ℃ None 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 hot rolling after impermeability 0.7MPa, 30min impervious JC / T 975-2005 Note: adhesion, shear strength test fresh concrete and dense-graded asphalt concrete bond between shear strength. 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 adequate ventilation, and the implementation of two hours shifts; required for protection of the eyes (3) construction, if splashed into the eyes should be rinsed immediately dipped in water after wipe with a clean towel, and consult a physician; (4) before spraying Construction Machinery, 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.
