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.

Development of light materials with height mechanical properties in the modern industries is one of the most critical issues.
Porous materials are light-weight structural materials with specific strength, heat emission effiency or filtering property.

Some investigations have made significant efforts to explore the introduction of advanced materials such as SMA which combines self-centering and energy dissipation properties (shape memory alloy) [1,2].
However, high expense and instability in phase transformation of SMA materials impede its practical application in recent years, and a broad acceptance of this retrofit in the construction industry has yet to be observed.
Shape memory alloys as new materials for aseismic isolation.
