| Abstract: | The enlargement rules of polymerization reactor for the synthesis of carboxylated styrene-butadiene rubber latex was studied based on the features of its synthesis process,homogeneous nucleation of emulsion and low-soap polymerization by the experiments on cold model and commercial plant.The improved tetrabladed inclined impeller and tetrabladed inclined impeller were recommended and a relation of power consumption for improved tetrabladed inclined impeller was obtained as Np=2.79(HL/D){(d/D)-1.4(B2/D)0.83-(d-2b1)/D]-1.4(b2-b1)/D]0.83(d-2b1)/d]5}.At non-geometric similarity condition,Pw was in the range of 0.44 to 0.79 kw/t,Nc was more than 8 times/min.The polymerization reactors of 12 m3,15 m3 and 20 m3 were designed based on the above enlargement rules. |
