Product Description

 

Product Description

Production Name:  formwork maker rubber balloon 

Rubber inflatable balloon is polymer composite materials processing product, it is the use of high-strength synthetic fiber fabrics ithstand 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 size, more pressure rubber inflatable balloon shapes, depending on the size of the bridge, gutter size, tunnel size, inflatablepressure 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 nextre-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.

Production Process

The production process of rubber inflated culvert balloon is divided into two types: cold bonding process and hot pressing vulcanization process.

• The cold bonding process involves first processing the raw materials into sheets (or purchasing finished rubber sheets), then cutting them into corresponding pieces according to the shape of the inflatable core mold, and finally adhering them together with adhesive to form the inflatable core mold.
• The hot-press vulcanization process involves directly vulcanizing natural rubber under heat and pressure, combined with anti-tear fabric, to form the specified shape of the inflatable core mold in a single molding process without any seams.

Usage requirements

 

Requirements for the rubber inflated culvert balloon for hollow core precast beams:

• When installing the rubber inflated culvert balloon, the length specifications of the hollow core precast beams are usually 8 m, 10 m, 13 m, 16 m, 20 m, 25 m, and 30 m; lengths exceeding 30 m are generally not designed as hollow core beams.
• For culvert balloons below 13 m in length, the inner culvert balloon is generally made of rubber; for culvert balloons above 16 m in length, there is more flexibility in the choice of inner culvert balloons, which can be rubber, wood, or steel.
• During the construction process, the rubber inflated culvert balloon is placed inside the rebar cage, inflated with compressed air to form the desired cavity shape, and withstands the pressure during concrete pouring. After use, it can be deflated and removed from the cavity, allowing for multiple reuse.
