Embodiment Construction
[0024] Such as figure 1 , figure 2 with image 3 Shown, polylactic acid bamboo charcoal slice production technique of the present invention, comprises the following steps:
[0025] (1) Add lactide and bamboo charcoal powder into the mixing tank 13 for stirring operation, wherein the weight of bamboo charcoal powder is 0.5% to 15% of the total weight of lactide and bamboo charcoal powder, stirring for 20 ~40min, until the mixture is uniform;
[0026] (2), open the first valve 14 at the bottom of the stirring tank 13, and drop the mixture of lactide and bamboo charcoal micropowder through the first pipeline 15 into the initial polymerization tank 16 through the first metering pump for preliminary polymerization operation. The temperature of the polymerization operation is 100-150 ° C, the time of the preliminary polymerization operation is 1-2 hours, and the pressure is 0.2 MPa. After the preliminary polymerization operation, the mixture of lactide and bamboo charcoal powder...
