Method for producing resinous particles |
摘要 |
<p>There is provided a method for producing resinous particles, containing: melting a mixture containing a binder resin and at least one additive having a melting point lower than T1/2 of the binder resin so as to prepare a molten material; atomizing resinous particles from the molten material in an atmosphere having a temperature higher than Tg of the binder resin and lower than 3 times of T1/2 of the binder resin; retaining the resinous particles in an atmosphere having a temperature higher than Tg of the binder resin, and lower than 1.5 times of T1/2 of the binder resin for 1 s to 15 s; and cooling and solidifying the resinous particles. There is also provided a method for producing resinous particles containing: melting the mixture so as to prepare a molten material; increasing a specific surface of the molten material in an atmosphere having a temperature higher than Tg of the binder resin, and lower than 3 times of T1/2 of the binder resin, so as to form a precursor; retaining the precursor in an atmosphere having a temperature higher than Tg of the binder resin, and lower than 1.5 times of T1/2 of the binder resin for 1 ms to 10 ms; cooling and solidifying the precursor; and atomizing resinous particles from the precursor.</p> |
