Study On Mechanical Properties Of Furan Resin Concrete And Structure Calculation Of Electrolytic Cell

Resin concrete is composed of resin and different size particle as binder and aggregate,after fully mixing,molding,curing to obtain a new composite material.Compared with the traditional concrete,it has good corrosion resistance,it is ideal material for product the electrolytic cell which work in a corrosive environment for a long time.At present,the cell made of furan resin concrete and vinyl ester resin concrete has replaced cement concrete electrolytic cell,and has been more and more widely used.Although the furan resin concrete compared with vinyl ester resin concrete has obvious advantage on price,but its mechanical properties is poorer,remains to be further improved.On the other hand,there is no standard to follow for the resin concrete electrolytic cell structure design.In the calculation work of resin concrete electrolytic cell,often only consider the function of structure load and ignore the influence of material properties and the thermal stress which produced by working temperature.At the same time,the resin concrete as a kind of viscous-elastic material,the existing structure design is not taken into consideration.In this paper,for the purpose of to improve the mechanical properties of furan resin concrete and perfect resin concrete electrolytic cell structure design and calculation method,the main work and achievements are as follows:(1)On account of the component characteristics and strengthening mechanism,analysis the factors that affect the strength of resin concrete regard it as a particle reinforced composites.At the same time the gradation design method are discussed.(2)Different formula of mechanics properties experiments are conducted,study the aggregate gradation,furan resin selection,coupling agent on the mechanical properties of furan resin concrete.Developped excellent mechanical properties of furan resin concrete,its compressive strength is 64.13 MPa,bending strength is 12.76 MPa,elasticity modulus is 15.3 GPa,which improved much than before.(3)The three-dimensional thermal-mechanical load finite element simulation model of the resin concrete cell consider the influence of material properties and the temperature load which produced by temperature,under different working condition are established.Calculation found that temperature load affect much on the stress and deformation,even more than the influence of the structure load.By using the power exponent creep model,calculated creep deformation and stress distribution after the cell serving 900 h.Analysis found that the creep deformation big and the maximum displacement of the wall compared to elastic phase rising 2 times but stress level declined.(4)According to calculation determine the size of wall thickness and make the electrolytic cell.Designing the load test scheme by simulating the cell actual working condition,measuring temperature distribution on the surface of the cell and deformation of the wall.The results showed that the cell structure in good condition,surface temperature and the deformation match well with the simulation results.
