Natural Materials Pneumatic Rubber Balloon Outstanding Resistance To Bulge - China

Used For Pouring Requirements Of The Hollow Components With Inflatable Rubber Balloon The performance characteristics of ARD inflatable rubber balloon 2 - Have good ageing resistance performance and long service life this product use synthetic rubber, natural rubber and strengthen layer vulcanize.

Has very good resistance to bulge, flexibility and elasticity, so can satisfy all sorts of work in the conditions of use.

4 - For building light-duty construction provides favorable conditions to stress hollow concrete component, due to the rubber mandrel, the weight than use stress solid component light 20%, so it can reducing the weight of the upper structure of building, can make the pile foundation short, increase span, make the construction become simple and safety.

5 - Construction technology is simple, safe, health, use it only need a few simple tools, without special process.

Only put the mandrel into negative reinforcement cage, inflate air to achieve work pressure, then pouring the concrete.

When the concrete freezing, put gas out mandrel, in thus complete the product component forming, and it not pollute the environment.

Technical parameters of pipe mandrel: - - - - dia(mm) | pressure (MPa) | 80 | 0.12 | 120 | 0.10 | 150 | 0.08 | 200 | 0.07 | 250 | 0.05 | 400 | 0.04 | 500 | 0.035 | 600 | 0.03 | 700 | 0.027 | 800 | 0.026 | 900 | 0.025 | 2200 | 0.005 | - - - - [Operating Instruction Manual] ARD rubber mandrel Using of rubber inflatable mandrel: 1 - Put the inflatable mandrel into the mold--pull inflatable mandrel into steel reinforcement cage, and make the vertical joints upward 2 - Start inflatable for mandrel (1) Open the valve and inflatable air to setted press, then close valve (2) Working press(See the sheet) 3 - Fixed (1)Because the inflatable mandrel will float upward when vibrated concrete, so you must fix up and down, and plus briquetting to overcome on buoyancy.

(2)For 250mm mandrel, the normal stirrup spacing is 80cm.

If the diameter increased, then the stirrup spacing will be reduced relatively.

4 - Pouring of concrete (1) The process of pouring of concrete is nearly same as solid constructed part (2) Using high frequency plug-in vibrating rods from both sides at the same time vibrators can avoid the mandrel moving around (3) The vibrating rod ends can not contact the mandrel, in case damaging the mandrel and leaking gas.

5 - as the concrete component solidification then can empty gas from the cavity, pulled out the capsule.

6 - Wash the mandrel, test pressure and inspect.

Storage and maintenance of inflatable mandrel A.

After using, you need wash the mandrel cleanly with water; when don't need to use, please storage the mandrel in the place of ventilated and dry, and don't touch with oils, acids, alkalis B.

During the process of using on the spot, please must avoid touch with sharp hard objects.

C.

Every time after pulling inflatable mandrel out the mold, please use brush(had better with nylon brush) and running water to wash, removing the concrete on surface in order to keep the mandrel clean.

D.

If the mandrel leak gas and sealing film off, you can use grinding wheel to burnish at the place needed repair and then brush glue to cover the sealing film; for the damaged place of fiber, you should use tape to cover for repairing.
