According to an embodiment, provided is a polycarbonate resin composition containing a polycarbonate resin, wherein a molded product of the polycarbonate resin composition has an integrated value of an amount of chemiluminescence derived from organic peroxide of 4,000 to 12,000 counts per mg of the molded product, and the integrated value of the amount of chemiluminescence is a value obtained by integrating the amount of chemiluminescence at a wavelength of 405 to 650 nm that is measured during 480 seconds in which under a nitrogen atmosphere the temperature is raised from 100°C to 350°C at a rate of 50°C/minute and thereafter is maintained at 350°C for 180 seconds.

A method of packaging a particle-like material includes: creating a state where an inert gas introduction pipe 71 and an inert gas exhaust pipe 73 being inserted into an airtight container 60, and where the airtight container 60 being filled up with a particle-like material 40, and then temporarily closing the opening portion 61; introducing an inert gas through the inert gas introduction pipe 71 into the airtight container 60, and discharging the inert gas introduced into the airtight container 60 out through the inert gas exhaust pipe 73, to thereby replace the inside of the airtight container 60 with the inert gas; and, removing the inert gas introduction pipe 71 and the inert gas exhaust pipe 73 out from the airtight container 60, and then closing the opening portion of the airtight container 60.
摘要:
The manufacturing apparatus (200) of the present invention comprises a die (201) for extruding a resin plate (110) and a first roller (230) and a second roller (240) for molding the resin plate (110). The manufacturing apparatus (200) further comprises: an inner deckel (205) for dividing the resin plate (110) and pre-forming a thick section; and a main molding section provided on the first roller (230) and/or the second roller (240) for molding a non-uniform thickness section from the thick section.
