[0025] Take 5~10g Enteromorpha and place it in a Soxhlet extractor. Use 80~100mL of 20% ethyl acetate ethanol solution to extract at 85~90℃ for 6~8h. After removing the lipid extract , And then add 40-50mL of 20% sodium carbonate solution to the Soxhlet extractor to extract polysaccharides at 58-62℃, filter and separate Enteromorpha slag; use the above-mentioned Enteromorpha slag with a mass fraction of 10% Sodium chlorite solution is immersed and oxidized for 2~3h, the filtrate is filtered and removed to obtain the residue. The residue is immersed in 40% potassium hydroxide solution for 5~10min and then washed with absolute ethanol to neutrality to obtain purified seaweed fiber Element; Put 70~80g kyanite ore in a ball milling tank, add agate ball milling beads with a diameter of 6~8mm, and mill for 30~45min to obtain kyanite powder. Combine kyanite powder and aluminum fluoride trihydrate by mass The ratio of 3:1 is mixed and put into the ball milling tank to continue ball mil...
