Guangzhou Petrochemical successfully trial production of new polystyrene product HG5108

Recently, Guangzhou Petrochemical successfully trial-produced the new product HG5108 of the polystyrene unit, and all the 139 tons of trial-produced products reached the standard of high-quality products
.

The new product HG5108 developed this time is optimized and upgraded on the basis of the existing product HG388 according to customer needs
.
HG5108 belongs to the middle melting index product, which is conducive to processing, and has the characteristics of high impact strength and high gloss.
It is mainly used to make high-end household appliances such as air conditioner shells
.

Due to the high viscosity of the HG5108 produced this time, it has a great impact on the stirring of the agitator, the transportation of the polymer pump, and the pressure difference control of the pelletizing die
.
In addition, in order to ensure the impact strength and gloss of the product, the production process needs to adjust the product formula, control parameters, etc.
, which increases the difficulty of operation
.

In order to ensure a successful trial production, before the production transfer, the technical management personnel of the device and the personnel of the R&D center discuss together to optimize the raw material formula and reaction parameters, and prepare the production plan in advance; during the production transfer, the technical personnel of the device will lead the shift to monitor the entire production process and adjust the process in time.
Parameters; the main operator closely monitors the control system, makes tracking and parameter optimization and adjustment according to the production situation, strengthens the control of reaction pressure and temperature, and ensures stable production; Temperature monitoring to ensure normal operation of the equipment
