Rubber inflatable balloon is polymer composite materials processing product, it is made of high-strength synthetic fiber fabrics withstand the force skeleton, inside and outside the vulcanized synthetic rubber adhesive protective layer of tape to do, according to the design dimensions of a high temperature curing process made specifications, more pressure rubber inflatable balloon shapes, depending on the size of the bridge, gutter size, tunnel size, inflatable pressure reaches the standard post-tensioned concrete pre-casting project tensioned beams, the initial setting of concrete grade to be after drain rubber inflatable balloon gas, pulled out after the rubber inflatable balloon, scrub clean after storage, until the next re-use, with a high compressive strength, good flexibility, strong tightness, and used repeatedly, is a new lower cost bridge construction, water conservancy, the tunnel project costs, and increase the speed of the amount of pre-engineering concrete products supporting products.

Accessories:
1>3-way valve, 0.1Mpa pressure gauge (connected to rubber balloons)
2>Powdered laundry soap as releasing agent(Water: soap powder = 20:1)
3>Evenly coated releasing agent on surface of balloons (At least 3 times)
In Molding
Penetration of bottom of concrete reinforcement cage by rope, put inflatable mouth outside.
Inflate the gas
1>Open the 3-way value to inflate the gas, detect and control the pressure by pressure gauge during inflating gas.
2>When the pressure up to the usage pressure (Usage pressure coding showed up on balloon surface), turn off intake valve.
3> No overpressure!
Fixed and pouring concrete
1>The rubber balloons float during jolt ramming, it should be fixed in up, down, left, right directions.
2>The method of pouring concrete is basically same as solid members', pay attention to High frequency inserted or vibrating simultaneously from both sides in case of rubber balloons make movement, vibrator head position is best not to touch rubber balloons.
Unload the molding
When the initial setting of concrete, open the bleed valve, and can pull out the rubber balloon, unloading mold time are depends on concrete type.
1>To keep clean, rubber balloons should be cleaned by brush (Nylon brush) using water to remove the concrete dust on surface after unloading mold.
2>Protect rubber balloons from sharp hard things on construction sites.
3> Put the rubber balloons in ventilated and dry environment, protect from oil, acids, alkalis after using
