Abstract
The invention discloses a method and a system for manufacturing organopolysiloxane. The system comprises N raw material tanks, N gauging tanks, a first reactor, a second reactor and at least one product tanks which are arranged in order from high to low. The manufacturing method comprises the following steps of: firstly, N raw materials are added into the N raw material tanks respectively. Then, a plurality of processing parameters about the organopolysiloxane are inputted to control the N gauging tanks to measure the dosage of the N raw materials according to the processing parameters, which along with a cyclic siloxane monomer are inputted into the first reactor. The first reactor is controlled to carry on ring-opening and re-distribution polymerization equilibrium reaction to the N raw materials and the cyclic siloxane monomer, so as to generate an intermediate product, and transfer the intermediate product into the second reactor. Finally, the second reactor is controlled to carry on a decomposition transient catalytic reaction to the intermediate product and a devolatilization operation to obtain the organopolysiloxane products.
