During ECAP, the strain and temperature rise will cause recrystallization in the materials, thereby causing the materials properties to change to some degree.
Once the ultrafine-grained materials underwent grain growth, it changed the refined material convert to ordinary coarse-grained material and lost its excellent properties.

Fiberglass reinforced plastic is considered as a homogeneous solid anisotropic material.
Especially, when the direction of winding angle of fiberglass coincides with main elastic direction of orthotropic materials, the expressions of critical values of axial force has been obtained.

Introduction Stirred reactor is a type of mixing equipment, widely used in chemical, pharmaceutical, metallurgy, paper making, cosmetics, coating materials, food, feed and water treatment and other industries, especially the use of chemical industry [1].
In the PVC polymerization reactor, the main role is to promote the stirring reactor material flow, so that the material is uniformly distributed in the reactor, increasing the mass and heat transfer coefficient.
Materials and catalysts is unevenly distributed, it will affect the quality of PVC, also can cause the polymer sticking to the wall, the polymerization process is not very good.
