Material: Rubber Dam dam reinforcement and protection tape by canvas canvas bear dam bag tension and ensure the tightness of the rubber layer.
Rubber layer is usually distributed in the outer layer of the dam bag, middle layer and inner layer, to play the effect of the rubber layer.
Outer rubber: as a result of more floating in the river, the use of wear-resistant, resistant to sunlight, heat, ozone and other properties of special rubber.
Middle rubber: direct protection of the canvas rubber layer, the two layer or multilayer canvas from the connection, the rubber and canvas to give better adhesion and resistance.
Inner rubber: in addition to protecting the canvas function, but also has a high water tightness and air tightness.
