Rubber, after being ground in a mill, is dissolved in styrene in a proper section and then added with chemicals and peroxide in a mixing section.
Mass reactions occur in the presence of solvent. Therefore, this mixture is sent to the polymerization section, the SUNKAIER usually consists of a series of 2/3 plug type reactors; The heat generated in the reaction is controlled by the hot oil circulating inside the coil. The layout of the entire reaction section is customized to meet specific requirements.
At the end of the reaction train, the polymer solution is sent to a devolatilization section, operated in two stages in series under vacuum conditions.
The monomer and low-boiling compounds are removed from the polymer, which is finally sent to the pelletizing unit.
The heat is provided by a thermal oil system. The vapour mixture, recovered by the devolatilization section, is condensed and then continuously recycled to the mixing section. Non-condensed vapours / inert gases from the vacuum system and liquid organic purge from the condensation section are recovered as fuel in a furnace, where thermal oil for the process is heated.
The finished polymer is pump to the pelletizing section to covert to pellets.
SUNKAIER can achieve turnkey engineering in polymer field and realize the overall contract of the whole production line, will greatly save the cost of transportation, installation and commissioning time. The setting of intensive device reduces the demand for floor space and reduces the cost of manpower and material resources. This design also reduces the frequency of personnel flow and contact, which greatly protects the safety of the construction personnel.
SUNKAIER pays attention to the quality and service.
