Combined with polycarboxylate-type water reducers compounded process demand of TangShan LongYi company. A control system based on the S7-300 PLC is developed, the fuzzy control and PID control algorithm have been used, and the accurate control of the reactor temperature and material adding rate is realized. Configuration software WinCC is adopted in the design of upper unit interface to make the operation and monitor easily. The engineering cost is reduced by the proposed control modules and actuators. The test results show that the final product:the flow of water reducing agent control in about 315 mm stably. The flow properties improved 16.67%.
