Neoprene bar is mainly composed of chloroprene rubber and various synthetic rubber as main raw materials, with various auxiliaries and fillers. It is plasticized, mixed, extruded, and high temperature vulcanized. It has the properties of aging resistance, oil resistance and abrasion resistance, and is suitable for application in face rockfill dam.
Specification model: commonly used (diameter) 12mm, 15mm, 20mm, diameter, 25mm, diameter, 30mm, diameter, 50mm, 70mm and production according to customer&＃39;s demand
Performance characteristics: dam type conventional sealing structure usually adopts three water stopping, namely in the setting of joint surface plastic sealing filler cover protection, sealing belt is arranged in a joint central copper seal in the bottom seam settings. The engineering practice shows that the central water watertight type bands in the construction is difficult to combine with concrete, often occurs at the same time in Water Leakage; joint displacement under the action of water in the seam with large strain, once destroyed, will reduce the sealing structure of utility. The flow structure is a watertight type defect. In view of the conventional central waterstop is difficult to play a normal role in terms of water, put forward a new type of sealing structure in the 95 period, the type of the middle sealing strip to the surface, the water seal belt is fixed in the seam position by embedded in the toe board and panel in angle and fixed bolt. In order to adapt to the large displacements of joints, the surface deformation ability of waterstop design into big wave shape; at the same time in order to ensure the sealing strip in the joint open bear high water pressure in the case of waterstop seam is arranged below the supporting rod of chloroprene rubber, chloroprene rubber rod should ensure to remain in the seam in the stop running, not be pressed into the joint to play a supporting role. Many years of production and sales of various engineering rubber products, with many years of production and sales experience, management and technical personnel, advanced equipment, for you to create the most solid foundation for quality.
Back stick type rubber waterstop with natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through plasticizing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, U type, Z type, T type, type, type H, E type Q type. The back sticking rubber sealing belt can be classified into buried rubber water stop belt and back sticking rubber sealing belt according to its use.
