Portion is connected with drain line, and liquid injection pipe road is equipped with pressure gauge, by injecting saturation lime in liquid injection pipe road direction elliposoidal utricule
Water stops fluid injection when until fluid pressure reaching 0.16~0.21MPa in elliposoidal utricule；
B, the liquid polyurethane being sufficiently stirred is injected into coating template and is paved with armored concrete upper surface, the poly- ammonia of liquid
Ester reacts end solidification in coating template and forms polyurethane initiation layer, and the extreme higher position of the polyurethane initiation layer is in elliposoidal
0.6~0.8 times of polar radius position of utricule；
C, the liquid polyurethane being sufficiently stirred is injected into coating template again, liquid polyurethane reacts in coating template
Terminate solidification and form urethane sealant layer, and the extreme higher position of the urethane sealant layer is higher than the extreme higher position 3 of elliposoidal utricule
~5mm；
D, drain line at quarterly intervals, is opened, the saturated limewater inside elliposoidal utricule is discharged, is closed after being completely exhausted out
Close drain line；It is then turned on fluid injection pipeline, injects saturated limewater into elliposoidal utricule, until the intracorporal liquid of elliposoidal capsule
Body pressure is that 0.16~0.21MPa closes fluid injection pipeline；It loops back and forth like this, completes the system of anti-reinforced concrete carbonation coating
It is standby.
Further, the elliposoidal utricule is made of chlorosulfonated polyethylene adhesive plaster material, can resist 200 DEG C or more high temperature, and
With corrosion resistance characteristic.
Further, the coefficient of foaming of polyurethane used in the polyurethane initiation layer and urethane sealant layer is 2.5~3.5
Times, and minimum thickness of the polyurethane initiation layer between elliposoidal utricule and armored concrete is 2~3mm.
Compared with prior art, the present invention is using elliposoidal utricule made of chlorosulfonated polyethylene adhesive plaster material, high-quality, corrosion resistant
Erosion, and 200 DEG C or more high temperature can be resisted, it can be when preparing polyurethane initiation layer and urethane sealant layer (due to being in liquid
Polyurethane temperature is higher) ensure the intact of elliposoidal utricule.Saturated limewater is filled in elliposoidal utricule, in carbon dioxide
After penetrating spheroid utricule made of chlorosulfonated polyethylene adhesive plaster material, carbon dioxide gas enters in elliposoidal utricule and saturation lime
Neutralization reaction occurs for water, to prevent the further infiltration of carbon dioxide gas, and periodic replacement saturation lime at quarterly intervals
Water, it is ensured that the absorbability of carbon dioxide gas in elliposoidal utricule.Used polyurethane foam multiple be 2.5~
3.5 times, cohesive force is strong, and flexibility is good, and compression strength is high, impervious good, has the infiltration of very strong barrier carbon dioxide gas
Ability.The saturated limewater that the coating takes full advantage of elliposoidal utricule has obstructed carbon dioxide and has invaded armored concrete
Erosion has protection effect good, can improve the durability and service life of concrete to the greatest extent.
