Description

Technical Field

[0001] This utility model relates to an auxiliary tool for the preparation of spiral carbon, specifically a cover for preparing spiral carbon by flame method. Background Technology

[0002] The flame method is a common method for preparing spiral carbon. The preparation process generally involves uniformly dripping a solution (such as SnCl4 solution) onto a substrate (such as a nickel sheet), drying it in an oven, then fixing the substrate with a clamp and burning it over an alcohol lamp flame, ensuring a constant distance between the ceramic wick at the top of the lamp and the substrate. After burning for a period of time, the black material covering the bottom surface of the substrate is collected, which is the spiral carbon. However, this preparation process has several problems.

[0003] 1. Combustion produces carbon dioxide, carbon monoxide, and some gases with irritating odors, which pose certain health hazards to operators.

[0004] 2. If you choose to operate in a fume hood, you need to turn on the fan. However, once the fan is turned on, the flame is prone to drifting and it is difficult to ensure the stability of the flame.

[0005] 3. The distance between the base and the top of the alcohol lamp wick cannot be flexibly adjusted. When replacing the base, the distance between the top of the alcohol lamp wick and the base needs to be readjusted, which is time-consuming.

[0006] Based on the above problems, it is necessary to design an auxiliary device for the flame method to prepare spiral carbon that can overcome the above defects. Utility Model Content
