Embodiment 1
[0030] Example 1 The degradable anoscope is composed of an outer cylinder and an inner core, both of which are prepared from degradable polymer main materials, reinforcing agents and lubricants of the degradable base material, and the injection molding method is as follows:
[0031] The first step, vacuum drying: vacuum-dry the degradable substrate pellets of Formula 1 or Formula 2 at 50°C for 5 hours, and set aside;
[0032] The second step, injection molding: add the dried degradable substrate pellets of formula 1 or formula 2 to an injection molding machine for injection molding.
[0033] The barrel temperature is set as follows: feed inlet 155°C, compression section 165°C, metering section 170°C, nozzle 165°C;
[0034] Mold temperature: 25°C;
[0035] The injection pressure is: the first section is 75pa, the second section is 80Mpa, and the third section is 50Mpa;
[0036] Injection time: 39 seconds;
[0037] The holding time is: 0 seconds;
[0038] The screw speed is:...
