Natural Rubber Material Of Inflatable Rubber Balloon / Culvert Formwork
The performance characteristics of Florescence inflatable rubber balloon
1. Design scientific and reasonable used inflatable rubber mandrel, or casting parts, finished product can meet the requirement of design, easy operation, save work, save time, save material.
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.
3.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 |

Operating instruction manual Florescence inflatable rubber balloon
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 φ250mm 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.
