Product Description

Product Description

Description of inflatable rubber formwork:

Inflatable rubber formwork 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.
The main shape of the inflatable core mold
Application:

Inflatable formwork has a variety of uses in the construction and engineering fields, mainly including:

1. Bridge Construction: Used for prefabricated or cast-in-place hollow beams and slabs, improving construction efficiency and reducing structural weight.
2. Culverts and Sewage Projects: Utilized in the construction of culverts and sewage pipelines to form the required hollow structures.
3. Hollow Slab Construction: In the technology of cast-in-place hollow slabs, inflatable formwork is used to create voids, enhancing material efficiency.
4. Water Conservancy Projects: In water conservancy projects such as dry docks, slipways, and piers, it is used to form hollows in concrete components.
5. Prefabricated Panel Manufacturing: In the production of prefabricated panels, inflatable formwork is used to create hollow parts, reducing the weight of the panels while increasing strength.

The advantages of inflatable formwork lie in its lightweight, ease of operation, reusability, and its ability to be soft and collapsible when not inflated, making it convenient to fold and roll. These features make it very popular in a wide range of engineering applications.

Packaging & Shipping

Packaging:

1.Plastic Film Wrapping: The airbags are tightly wrapped in plastic film to protect them from water, dust, and abrasion during transit.
2.Palletization: Airbags are usually placed on pallets for ease of loading and stacking. Palletization also helps to protect the airbags from damage.
3.Securing: On the pallet, airbags may be secured with ropes, tapes, or other fastening materials to prevent movement during transportation.
 

Shipping:

1.Sea Freight Containers: Given the large size of pipeline blocking airbags, sea freight is a common method of transportation. Containers provide a secure and protective environment to prevent damage during long-distance shipping.
2.Container Types: Depending on the size and weight of the airbags, standard 20-foot or 40-foot containers may be used, or special-sized containers may be required based on the needs.
3.Securing Inside Containers: Inside the containers, airbags and pallets are properly secured to prevent movement or tipping during transit.
