Underground engineering rubber seal series is a new type of rubber seal component, it absorbs and summed up the experiences of success for a period of time since the engineering design and construction in the field, its development marks the successful in material engineering technology field, engineering leakage prevention technique widely used in forward again stepped into the step.
　　 The series of products has been widely used in a variety of different types of reinforced concrete self waterproof of underground structure engineering, especially for attached building basement, underground shopping malls, underground garage, underground pedestrian passageway, underground water diversion project, caisson, flood prevention wall highway especially applicable. The series of products has under non-uniform relative displacement of large, simple construction, many specifications, wide applicability, waterproof structure reasonable, economic and beautiful, anti-aging, excellent resistance to ductility many characteristics.
　　 Underground engineering rubber waterstop products materials, natural rubber, chloroprene rubber, ternary ethylene propylene rubber, acrylonitrile butadiene rubber (NBR) designed to select should according to the specific engineering deformation joint requirements: tensile strength, ductility, tensile permanent deformation, anti-aging properties, underground water or corrosive medium, soil pests, waterstop short-term or long-term exposure to oil or in contact with the oil calculation of structural displacement burying the depth and a water pressure is related to the specific situation and decide.
一、product introduction
　　 ACF in case of water swelling rubber with the performance of the general rubber products, and meet water self expanding the unique properties of new type waterproof material, the volume expansion rate of 100% to 300% energy to to the role of water sealing, waterproof effect than ordinary rubber is more reliable.
二、Characteristic and graceful
　　 Effect of joints; and the use of ACF in case of water swelling rubber than ordinary rubber has more excellent characteristics and advantages, expand the rubber product range. Its expansion value depends on the types of meeting water contact structure is simple, the installation is convenient, time-saving, safe; part of the encounter water or moisture will produce than the original 2 ~ 3 times the volume expansion ratio and full of all the joints irregular surface, hole and gap, also have a certain contact pressure to prevent water leakage, high rate of expansion, so that the sealing strip to allow arbitrary deformation. It can long-term blocking water and chemical penetration, thermal expansion coefficient is not affected by external water than Any ordinary rubber with plasticity and elasticity, high ageing resistance and corrosion resistance; have enough to withstand the external pressure of the ability of excellent mechanical properties, and long-term to maintain its flexibility and performance, no pollution to environment.
三、quality standard
　　 ACF type water swelling rubber product standard as shown in the following table, water swelling rubber surface should be clean and smooth, no scratches, bubbles and other impurities, the edge is neat.
