In order to reduce the production process fluctuation, influence of resin quality, has a unique DCS temperature control system Huakai resin production line, the stability of the entire process control. The benefits of DCS systems that can accurately and timely adjustment of production parameters, automatic recording of all process and preserved in the central computer.

Dissolved in the PVA process, the temperature must be controlled accurately, to ensure that the PVA can be completely dissolved, and does not produce particles during dissolution, the effect after the condensation reaction, condensation reaction is the production of PVB resin is the most important, needs a stable temperature so as to complete the reaction process, reduce the residual unreacted material. Finally in the air drying system, because the temperature will directly affect the resin moisture, DCS temperature control system can guarantee the resin moisture equilibrium distribution.
