Styrene resin underwater granulation technical transformation success

Fushun Petrochemical Chemical Plastics Factory 5000 tons/year styrene-butadiene transparent impact resistance resin industrialization test equipment granulation system adopts the first set of underwater granulation technology to reform, and successfully opened up all processes at the end of last month to achieve a successful drive.

The successful production of a 5,000-ton/year butyl benzene transparent impact resin device proves that the domestic underwater granulation technology and equipment are reliable, especially the successful operation of the gear pump and pelletizer as the core equipment of this device. It indicates that the bottleneck problem of the first domestic underwater pelletizing system has been completely solved, and it also marks a solid step in the industrialization process of Ding-Ben transparent impact resin, one of the key projects of CNPC. The implementation of underwater granulation technology will enable comprehensive improvement of the comprehensive technical indicators of styrene-butadiene resin, including product haze, impact strength and many other technical indicators that will meet or exceed the international level of similar products.

At present, the plant is further optimizing the transformation of the device to solve the problem of load matching extruder, in order to achieve continuous operation within the year.
