Army bridge Hebei rubber production of rubber inflatable mandrel, are made of rubber and fiber reinforced layer made of vulcanized products with high tensile strength, elasticity and tightness, back filled with compressed air, to replace the original wood mold, bamboo mold, steel. Can be used repeatedly, it is a lower cost and speed up the construction progress of concrete products supporting products. Rubber inflatable mandrel performance characteristics of rubber inflatable mandrel 2 scientific and rational design, the application of rubber inflatable mandrel, prefabricated or site pouring out of the finished components, rubber inflatable mandrel all can meet the design requirements, and simple operation, saving labor, , the provincial timber. Especially in a small rubber inflatable mandrel cavity were unable to solve the difficulties of the construction of the inner member into the form removal. 3, rubber inflatable mandrel has a good anti-aging properties, long service life. 4, rubber inflatable mandrel with chloroprene rubber, natural rubber and nylon fabric pre-synthesis, made after the curing process after use. Very good resistance expansion strength, and elasticity and flexibility, resistance to high temperature and good out of. Fully meet the construction environment under different conditions. 5, rubber inflatable mandrel in the range of -10 ℃ ~ + 90 ℃, the material does not change. Prestressed hollow concrete structures, the use of rubber inflatable mandrel, its weight is lighter than non-prestressed solid component of 25%, for the construction site construction lighter and therefore provide favorable conditions to reduce the weight of the upper structure of the building, the pile can be shortened, span increases. When using rubber inflatable mandrel coated with a release agent (see the manufacturer's instructions), rubber inflatable mandrel conduct leak tests, (which is very important in case of pouring concrete into the discovery of leaks in appearance, member on damage) will be no exception rubber inflatable mandrel pulled into the steel cage, filling pressure to work pressure, the pouring of concrete, to be the initial setting of concrete (time see instructions), the rubber inflatable mandrel out of deflation, to complete the molding of the finished component, do not pollute the environment. 24 hour free technical advice, please contact us to discuss business, we will be happy to serve you.
