PVB resin production

Product introduction

Resin production equipment:

Huakai has the largest PVB resin powder (raw material) production line

Huakai has the country's most advanced set of resin production line, including dissolution, condensation, washing and air drying, full automation system are imported techniques, reduce manual operation mistakes, to ensure the stable quality. The raw material is the most important factor deciding the PVB film quality, so we focus on the production process and testing.

DCS temperature control system

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.

In the control system

The control system is tested for each step in the production of the product quality, to ensure that the product complies with the requirements of the next process. In the control detection is very important to the resin product quality, we pay attention to every detail. For example, in the dissolution of PVA, we can detect the concentration of the solution, to determine the correct component in the feed of PVA. After the condensation we need pH and residue components inspection solution condensation process, to ensure smooth.

Resin quality detection

In the PVB resin into film production line, we will carry out self inspection for each batch of resin, test items include viscosity, volatility, transparency, acid value, each index of mechanical, optical and high consumption of film have a major impact on performance. Resin detection system Huakai system can ensure the stability of PVB film.
