Purely based on the elasticity, viscosity or plasticity theory theory can not meet these
materials processing requirements of the deformation process. So based on the nature
of the complex mechanics of the research topic - rheological theory will be referred to

the lion's share of the market, consume about 80% of the volume of rubber resources.
Therefore,
the

is
also
important.

of the people is to determine awareness of changes and developments. Any material

For the rubber industry development, not only the normal process of production
of rubber products. Mechanical technology and the increasing need in-depth study of
