step three, crushing the bamboo charcoal in the step two to prepare nano bamboo charcoal powder;
step four, mixing the bamboo charcoal powder into terylene or viscose raw pulp and stirring to uniformly disperse the bamboo charcoal powder in the raw pulp;
spinning into bamboo fibers, and pressing into a bamboo fiber board;
the extraction process of the mugwort concentrated solution comprises the following steps:
step one: cleaning folium Artemisiae Argyi, drying, and grinding into powder;
step two: adding two zeolite particles into a constant temperature beaker, and adding an extractant;
step three: pouring the solution obtained in the step two into an extraction cylinder filled with mugwort leaf powder; wherein, a filter device is arranged in the extraction cylinder;
step four: preparing a Soxhlet extractor, cleaning, drying, placing a Soxhlet extractor between an extraction cylinder and a beaker, performing reflux extraction, and stopping heating and cooling the extracting solution when the color in the extraction cylinder becomes very light;
wherein the dosage ratio of mugwort leaf, zeolite and extract is: 10g 5g 300ml.
