Section adopts the thickness structure which is divided into subpowerful district and water district, so that each part has uniform, reasonable force. The outer wall surface of the stretch shrinkage is plane, the construction of the formwork folder system is not easy dislocation; steel plate connected to additional mounting holes and reinforced rigid fixation is not easy displacement. Good adhesion to galvanized steel and concrete makes the waterproof performance better.
Application Field:
Types: NR means natural rubber; CR means chloroprene rubber; NBR means nitrile Butadiene Rubber
Code No: QJ means produced by our company
Type HJGB (NR )means the rubber water stop produced by our company. Its width is 350mm, material is natural rubber and it is applied to the freshwater seepage control project and applicable temperature is -40~60°C.
Type HJGB (CR )means the rubber water stop produced by our company. Its width is 350mm, material is neoprene and it is applied to chemical and other sewage seepage project and applicable temperature is-35 ~ 60 °C.
Type HJGB (NBR )means the rubber water stop produced by our company. Its width is 350mm, material is nitrile rubber and it is applied to sewage seepage control project which contains petroleum oil and so on and applicable temperature is-35 ~ 60 °C.
