Inflatable RUBBER Bladder Bag

Inflatable bag is made of high strength and good water resistance nylon canvas

   

rubber bladder of water dam is a kind of hydraulic structure, construction with advanced technology. A rubber dam is made of high Strength and good water resistance nylon canvas and aging durable compound rubber supported by a frame and prefabricated rubber, riveted store water. Discharge the water or air in the dam tube when no need to store water. Advantages of rubber dam are shorter construction period(final construction period 3-6 months). Less engineering budget and it can save 40% than that of civil works. Rubber dam on the concrete base board to form a sealed bag shaped space inflated water or air to has the features of long service life, simplified maintenance and improved vibration resistance.

The rubber dam is suitable for the projects with lower water level and large span sluice, widely used for irrigation, power generation, flood control and urban landscaping.

The Rubber Bladder is made up of 90% EPDM rubber which resists weathering, ozone, ultra violet light, the effects of extreme temperatures and significantly out-performs CR rubbers which are more commonly used.

The outer layer ID made of thespecial Rubber material characterized by wear resistance, sunlight resistance, heat resistance and ozone resistance

The Middle layer is used for protection of canvas and for connection of 2 or more canvas with Rubber layers.

The inner layer is used for protection of canvas and for connection of 2 or more canvas with Rubber layers.
