Polymerizing-kettle Temperature Control Method Based On Unit Model;

The paper summed up the studies of temperature’s control system of polymerizing-kettle, which covered both here and abroad in lately twenty years.

The algorithm characteristics for controlling of polymerizing-kettle temperature are non-linear, strong inertia,time-variant, and with pure delay.

The simulation result,which is obtained by applying the method to control the temperature of latices polyreactor,shows static error is effectively reduced and the robustness of the new approach in controlling temperature shock in the process of p.

And attempts for the first time apply the PSO algorithm in the temperature control of Polyreactor and the beer saccharification.

Primary factor influcing rate of fault shut-down of polymerization reactor is found out through statistics and analysis.

12 kJ/mol, the polymerization rate increases with the increase of reaction temperature; the type of solvent .

The experimental results show that both high polymerization rate and high molecular weight can be achieved at 50℃ with taking high active ammonium persulfate (APS)/triethanolamine (TEA) as initiator system.

Via the experiment,the effect of different kinds of agitator (4blade pitched turbine and Brumagin impeller)and agitator intensity on fluid mixing,polymerization rate,latex particle size and polymerization stability of BuSt2Vp emulsion copolymerization was determined.

The photo-polymerization rate of HBUA was charactered by photo-calorimetry(Photo-DSC).
