TD-A2 Passenger Dedicated rubber bearings install a special grout, use: Passenger Line for all types of cast bridge rubber bearing mounting Second, the technical characteristics: early strength, high strength, high fluidity (gravity), no shrinkage, Anti-oil seepage 1, the early strength, high strength: the strength up to 50MPa or more a day, a day after the device is installed to run production. 2, gravity-state: the scene just after mixing with water, poured into the device directly to the foundation, without shock ramming equipment foundation can fill all voids. 3, micro-expansion: in order to ensure close contact between the device and the foundation. 4, no rust effect: steel, steel and other non-corrosion hazard. 5, anti-oil seepage: 30 days immersed in the oil intensity than before the immersion oil increased by more than 10%. 6, Durability: 2 million times fatigue test, 50 freeze-thaw cycle experiments no significant changes in intensity. 7, good weather resistance -40 ℃ ~ 600 ℃ long-term safe use. Third, technical indicators: (Standard: Passenger Line bridge rubber bearing basin cast provisional technical conditions) Free Performance Model coagulation time min fluidity (mm) strength (MPa) elastic modulus expansion ratio (%) Other anti-bending Pressure TD-A2 initial set final setting initial 30min 24h 2h 24h 28h 28d 28d no bleeding, no corrosion of steel> 30 <80 290 245> 7.5 - ≥50 ≥80 32GPa 0.08 Fourth, packaging, storage 1, the product of plastic bags packaging specifications for the 50 kg / bag. 2, the product unopened, should be in a dry, cool, ventilated place to store packaging. Under normal conditions of storage and transportation, shelf life of 12 months.
