Title:
MANUFACTURING APPARATUS AND MANUFACTURING METHOD FOR LIQUID CRYSTALLINE POLYESTER RESIN PELLETS
Document Type and Number:
WIPO Patent Application WO/2015/152175
Kind Code:
A1
Abstract:
A manufacturing apparatus for liquid crystalline polyester resin pellets that is provided with: a die head with a discharge port for discharging melted liquid crystalline polyester resin supplied to the die head from a reaction tank via a valve; a cutter for cutting the resin discharged from the die head and solidified; and at least one perforated plate located downstream of the valve and upstream of the discharge port. The pore diameters of multiple spinneret holes provided in the discharge port are 3 mm - 6 mm and the mean pore diameter in the perforated plate is 0.1 - 1.2 times the pore diameter of the spinneret holes. A manufacturing method for liquid crystalline polyester resin pellets for cutting liquid crystalline polyester resin, which has been discharged from the die head of said apparatus via the discharge port so as to form groups of strands and solidified, into pellet form. Provided is a manufacturing method for liquid crystalline polyester resin pellets, the method having excellent discharge stability and being able to improve continuous batch productivity and pellet quality in the step for discharging the melted resin as groups of strands.
