Embodiment 1
[0043] In this example:
[0044]1) Preparation method of cooling granules: In terms of parts by mass, take 20 parts of 80-mesh polyethylene and 80 parts of ethylene / vinyl acetate copolymer. After mixing evenly, use a commercial screw extruder to blend, melt, extrude, granulate and spheronize. Take 20-35 mesh particles to obtain low-adsorption cooling particles, and the particle bulk density is 3.0g / ml; 2) Preparation method of cooling particle sticks: The prepared low-adsorption cooling particles are continuously sent to three serially distributed through the conveyor belt. Cavity components (structural schematic diagram as figure 2 shown), the center of the mold cavity is a circular channel with a circumference of 23.5mm. The first mold cavity is provided with a negative pressure to compress and accumulate the particles in it. After being wrapped with cloth tape, it is sent to the second mold cavity with a heating device. The granules in the mold cavity are heated to 120°C,...
Embodiment 2
[0046] 1) Preparation method of cooling granules: In parts by mass, take 70 parts of 100-mesh ethylene / vinyl acetate copolymer, 10 parts of polyethylene oxide, and 10 parts of polyvinyl alcohol. After mixing evenly, use a commercial screw extruder to blend and melt extrude After granulation and rounding, take 15-25 mesh particles to obtain low-adsorption cooling particles, and the bulk density of the particles is 2.5g / ml; 2) Preparation method of cooling particle rods: The prepared low-adsorption cooling particles are continuously fed into the Three mold cavity components distributed in series, the center of the mold cavity is a circular channel with a circumference of 23.5mm, the first cavity is provided with a negative pressure to compress and accumulate the particles in it, wrapped with cloth tape and sent to the second with a heating device The second cavity, in which the particles are heated to 115°C, the particles are partially softened and initially bonded, and then sent...
Embodiment 3
[0048] 1) Preparation method of cooling granules: In parts by mass, take 65 parts of 150-mesh polylactic acid, 10 parts of polyethylene glycol, 10 parts of polyvinyl alcohol, 10 parts of polyethylene, and 5 parts of paraffin wax, mix them evenly, and extrude them with a commercial screw Extrude, blend, melt, extrude, granulate and spheronize, take 30-60 mesh particles to obtain low-adsorption cooling particles, and the particle bulk density is 2.0g / ml; 2) Preparation method of cooling particle rods: Pass the prepared low-adsorption cooling particles through The conveyor belt is continuously fed into the three mold cavity components distributed in series. The center of the mold cavity is a circular channel with a circumference of 23.5mm. The first mold cavity is equipped with a negative pressure to compress and accumulate the particles in it. The cloth belt is wrapped and sent to The second cavity with a heating device, in which the particles are heated to 105°C, the particles a...
