Embodiment 1
[0044] A 3D printing self-suspension photocatalytic device preparation method is divided into the following steps:
[0045] 1) Mix 8 kg ABS and 2 kg TPU through a high-speed mixer, and then melt and blend them through a twin-screw extruder. 155°C, 165°C in the fifth zone, 185°C in the sixth zone, 195°C in the seventh zone, 180°C in the eighth zone, 170°C in the ninth zone, 165°C at the die head, and a rotation speed of 200 rpm. Extrude and granulate to obtain wire masterbatch;
[0046] 2) Melt and extrude the wire masterbatch obtained in step 1) through a single-screw extruder. The parameters of the single-screw extruder are: 120°C in the first zone, 180°C in the second zone, 195°C in the third zone, and 170°C in the fourth zone. 50 rpm, the extruded wire is cooled by water, and the tractor pulls and controls the wire diameter to make a wire with a wire diameter of 1.75±0.05 mm;
[0047] 3) Design a square sheet with a side length of 5 cm, a height of 0.2 cm, and a wall thick...

[0052] A 3D printing self-suspension photocatalytic device preparation method is divided into the following steps:
[0053] 1) After mixing 8.5 kg ABS and 1.5 kg TPU through a high-speed mixer, melt and blend them through a twin-screw extruder. 170°C, 185°C in the fifth zone, 195°C in the sixth zone, 200°C in the seventh zone, 190°C in the eighth zone, 175°C in the ninth zone, 165°C at the die head, and a rotation speed of 150 rpm. Extrude and granulate to obtain wire masterbatch;
[0054] 2) Melt and extrude the wire masterbatch obtained in step 1) through a single-screw extruder. The parameters of the single-screw extruder are: 120°C in the first zone, 190°C in the second zone, 200°C in the third zone, and 170°C in the fourth zone. 50 rpm, the extruded wire is cooled by water, and the tractor pulls and controls the wire diameter to make a wire with a wire diameter of 1.75±0.05 mm;
[0055] 3) Design a circular sheet with a radius of 2 cm, a height of 0.2 cm, and a wall thic...

[0060] A 3D printing self-suspension photocatalytic device preparation method is divided into the following steps:
[0061] 1) After mixing 7 kg ABS and 3 kg TPU through a high-speed mixer, melt and blend them through a twin-screw extruder. The twin-screw parameters are: 90°C in the first zone, 120°C in the second zone, 145°C in the third zone, and 145°C in the fourth zone 160°C, 170°C in the fifth zone, 180°C in the sixth zone, 185°C in the seventh zone, 175°C in the eighth zone, 165°C in the ninth zone, 160°C at the die head, and a rotation speed of 220 rpm. Extrude and granulate to obtain wire masterbatch;
[0062] 2) Melt and extrude the wire masterbatch obtained in step 1) through a single-screw extruder. The parameters of the single-screw extruder are: 120°C in the first zone, 170°C in the second zone, 185°C in the third zone, and 170°C in the fourth zone. 45 rpm, the extruded wire is cooled by water, and the tractor pulls and controls the wire diameter to make a wire wi...
