Erosion Under The Condition Of The Rubber Material Mechanical Performance Test Research

With The Continuous Development Of The Bridge Construction, Rubber Bearing Has Gradually Become An Important Part Of The Highway, Railway And Other Bridges In China. A Wide Variety Of Bridge Span Bridge In Our Country Continue To Emerge, Which Reflects The Advanced Level Of Construction Of Our Country At The Same Time, The Bearing Capacity Of The Bridge Bearing Capacity, Durability, Bearing Displacement And Corner Capacity And Other Performance Requirements Continue To Improve. Rubber Bearing Role Mainly In The Following Aspects: The First Is To The Upper Structure Load Reliably Transfer To The Pier, And End Structure Displacement And Rotation Of The Deformation Caused By The Load Bearing; The Second Is To Adapt Due To Temperature, Humidity And Other Environmental Changes Caused By The Structure Of Swelling Shrinkage Deformation Of; Three Can Be Impedance Wind And Earthquake Waves Caused By Structure Shift And Reduce The Vibration On The Structure Of The Adverse Effects. Rubber Bearing With Rubber Materials Include Natural Rubber, Chloroprene Rubber, Ethylene Propylene Rubber, Poly Isoprene Rubber, Polybutadiene Rubber And So On, According To The Actual Situation Of Our Country, Promulgated By The Ministry Of Communications JT/T4-2004 Standards And Requirements For Rubber Bearing Rubber Material Must Be Natural Rubber And Chloroprene Rubber. Ordinary Rubber Bearing In The Production And Use Of The Process, Due To The Material Quality And Aging, Design And Construction, And Other Reasons, Often Rubber Bearing Aging Cracking, Shear Overrun And Other Diseases, A Serious Threat To People's Safety. Therefore, The Study Of The Two Kinds Of Rubber Materials Is A Prerequisite For The Rubber Bearing.In This Paper, We Mainly Deal With The Natural Rubber, Which Has Been Carried Out By Freezing Thawing, Salt, Heat, Aging, Sulfuric Acid, Nitric Acid And Sulfuric Acid. The Corrosion Of The Rubber Is Soaked In PH=4.5. In Freezing Thawing And Salt Freezing, 20, 40 And 60 Times Of Rapid Freezing And Thawing Were Performed. The Other Corrosion Treatments Were Quick Corrosion, 40, 60 And 20 Days Respectively;The Corrosion Process Of The PH=4.5, Including The Sulfuric Acid, The Corrosion Of The Acid, The Corrosion Of The Sulfuric Acid, The Corrosion Of The Acid, The Corrosion Of The Sulfuric Acid, The Corrosion Of The Acid, The Corrosion Of The Sulfuric Acid, The Corrosion Of The Acid, The Corrosion Of The Acid, The Corrosion Of The Acid, The Corrosion Of The Acid, The Corrosion Of The Rubber, The Corrosion Of The Rubber. In Freezing Thawing And Salt Freezing, 20, 40 And 60 Times Of Rapid Freezing And Thawing Were Respectively. The Other Corrosion Treatments Were Quick Corrosion Of 20, 40 And 60 Days Respectively;In View Of The Properties Of The Natural Rubber And Steel Plate, The Freezing Thawing, Salt Freezing, Heat And Moisture, Heat Aging Treatment. In Freeze-Thaw And Salt Freezing Experiment, Respectively, Of Specimens Of 20, 40, 60 Times Of Rapid Freezing And Thawing; Damp Heat And Thermal Aging Treatment Is 20, 40, 60 Days Of Rapid Corrosion Of The Specimens, Respectively, After Erosion Events Were 90 DEG Glass Adhesion Strength Test;The Bonding Property Of The Rubber And Steel Sheet Was Carried Out, And The Freezing Thawing, Salt Freezing, Heat And Moisture, Heat Aging Treatment Were Carried Out. In Freeze-Thaw And Salt Freezing Experiment, Respectively, Of Specimens Of 20, 40, 60 Times Of Rapid Freezing And Thawing; Damp Heat And Thermal Aging Treatment Is 20, 40, 60 Days Of Rapid Corrosion Of The Specimens, Respectively, After Erosion Events Were 90 DEG Glass Bonding Strength Test.
