▎ 摘　　要

NOVELTY - Composition has 15-20 pts. wt. molybdenum-containing compound, 20-30 pts. wt. graphene composite material, 8-12 pts. wt. biochar active, 4-6 pts. wt. auxiliary agent, 8-12 pts. wt. dispersant, 15-20 pts. wt. polyaspartic acid, 6-10 pts. wt. sodium citrate and 25-30 pts. wt. water. USE - Composition for use in the rust remover (claimed). ADVANTAGE - The residual moisture in a sieving cylinder is effectively dried. The high-temperature is transferred to an elastic telescopic rod, so that it deforms and stretches when heated, and the residual moisture in the sieving cylinder is mixed and reacted with an effervescent disintegrating agent to generate a large amount of carbon dioxide gas, so as to effectively improve the efficiency of a drying device. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparation method of composition, comprising: (i) mixing and stirring molybdenum-containing compound, biochar active, auxiliary agent and water in potential energy reaction kettle at 20-25 degrees C, (ii) heating the mixture obtained in (i) at 50-65 degrees C, and adding dispersant and graphene composite material, and (iii) mixing and stirring the mixture obtained in (ii) for 20-25 minutes, cooling to room temperature, adjusting pH, adding polyaspartic acid and sodium citrate, ultrasonic dispersing for 30-35 minutes, and vacuum extracting and evaporating to the original volume of 40-45%; and (2) a rust remover. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of rust remover.
