[0018] First, take 8kg wood chips and put them into an extruder to extrude them into blocks, then put them into a carbonization furnace for 1 hour, and set the temperature at 250°C. Grind into 200-mesh powder; then take 3kg of lard and put it into a container, then add 2L of ethanol solution with a mass fraction of 96% to it, stir and heat, and set the temperature to 40°C. After the lard is completely dissolved, put the above-mentioned Put the powder into a container, then add 1L of potassium hydroxide solution with a mass fraction of 35%, stir for 40min, then cool to 20°C, and filter; then air-dry the above obtained filtrate naturally, put it in a container, Add water to it to submerge the filtrate by 2cm, then add 800g sodium dodecylsulfonate to it, stir evenly, set the temperature at 35°C, then add 600g polyacrylamide to it, and stir for 2h; then wait until the above stirring is completed , stand still for 15 minutes, add 145g of 2-hydroxyethyltrimethylammonium chloride to ...

[0024] First take 10kg of sawdust and put it into an extruder to extrude it into blocks, then put it into a carbonization furnace for 2 hours, and set the temperature at 290°C. After carbonization, take it out and cool it to 35°C, and put it into a pulverizer. Grind into 300-mesh powder; then take 4kg of lard and put it into a container, add 3L of ethanol solution with a mass fraction of 96% to it, stir and heat, and set the temperature to 50°C. After the lard is completely dissolved, put the above-mentioned Put the powder into a container, then add 3L of potassium hydroxide solution with a mass fraction of 35%, stir for 50min, then cool to 25°C, and filter; then air-dry the above-mentioned obtained filtrate naturally, put it in a container, Add water to it to submerge the filtrate by 3cm, then add 900g sodium dodecylsulfonate to it, stir evenly, set the temperature to 40°C, then add 800g polyacrylamide to it, and stir for 3h; then wait until the above stirring is completed , ...
