Secondly, the same process has different choices of production materials, The quality of produced rubber hollow plate air bags also varies greatly, Natural rubber and synthetic rubber The strength selection of the anti pulling cloth directly affects the quality of the rubber hollow plate airbag products and the service life, that is, the number of cycles.
Usage of rubber hollow plate airbag
1. Injection of rubber airbag
A Evenly apply mold release agent on the surface of rubber airbag.
B. Pull the rubber airbag into the reinforcement cage with concrete at the bottom by a rope, and place the inflation nozzle of the inflatable core mold outside.
2 Inflation of rubber hollow plate airbag
A Open the air inlet of the rubber airbag valve inflation. For inflation Pressure gauge Control and monitor the air pressure.
B When the air pressure reaches the service air pressure, close the air inlet valve.
C The special-shaped inflatable core mold shall be inflated alternately until the service air pressure is reached.
D. Pay attention not to overpressure during use.
3. Fixation and concrete pouring of rubber hollow plate air bag
A The rubber bladder will float when vibrating the concrete, so it must be fixed up, down, left and right. Generally, the stirrup spacing of the core formwork with a diameter of 250 mm is 80 cm. If the diameter increases, the spacing will be reduced accordingly.
B. The concrete pouring method is basically the same as that of core construction. Pay attention to the use of high-frequency insertion or vibrating rod to vibrate from both sides at the same time to prevent the displacement of the rubber bag from left to right. The end of the vibrating rod shall not touch the core mold.
4 Formwork removal of rubber hollow plate airbag
When the concrete is initially set, open the valve to deflate, and then the rubber bag can be pulled out. The time of formwork removal can be determined according to the cement number.
5 Flush the rubber bladder and test the water. Please take it off for storage so that the rubber airbag can be reused.
