Example Embodiment

[0016] Example 1

[0017] Step 1: Integrated preparation of wick 1 and cup body 2. After mixing 28g of diatomaceous earth and 72g of alumina, take 95g of mixed powder, add 5g of MoSi2 powder, ball mill the mixed powder with a ball mill for 12 hours, and add the powder after ball milling Mix 10g of starch, add water to prepare a slurry, with a solid content of 30wt%, pour the slurry into a mold of the corresponding shape, and then place it in an oven at 150°C for 3 hours, and place the dried sample in a covered ceramic crucible In the process, a porous ceramic with mullite whisker structure is obtained after debinding and sintering in a resistance furnace. The specific heating program is to heat up at 1°C / min to 300°C for 1 hour, then continue to heat up at 1°C / min to 600°C for 2 hours to debinding, continue to heat up at 5°C / min to 1300°C for 2 hours, and cool down with the furnace to get the appearance Cylindrical porous mullite ceramic with needle-like structure, with a porosi...

[0021] Step 1: Integrated preparation of wick 1 and cup body 2. After mixing 28g of diatomaceous earth and 72g of alumina, take 97g of mixed powder, then add 3g of MoSi2 powder, and mill the mixed powder with a ball mill for 15 hours. The powder after ball milling Add 15g starch and mix well, add water to prepare a slurry with a solid content of 40wt%. Pour the slurry into a cylindrical mold with a diameter of 2cm and a depth of 5cm, and place it in an oven at 150℃ and bake for 3 hours. In a ceramic crucible with a lid, a porous ceramic with a mullite whisker structure is obtained after debinding and sintering in a resistance furnace. The specific heating program is to heat up at 2°C / min to 300°C for 1 hour, then continue to heat up at 1°C / min to 600°C for 2 hours to debinding, continue to heat up at 5°C / min to 1400°C for 2 hours, and cool down with the furnace. Porous mullite ceramics with a shape structure, with a porosity of 78% and a pore size of 2um.

[0025] Step 1: Integrated preparation of wick 1 and cup body 2. After mixing 28g of diatomaceous earth and 72g of alumina, take 99g of mixed powder, then add 1g of MoSi2 powder, and mill the mixed powder with a ball mill for 18 hours. The powder after ball milling Add 10wt% starch and mix well, add water to prepare a slurry with a solid content of 60wt%. Pour the slurry into a cylindrical mold with a diameter of 2cm and a depth of 5cm. Place it in an oven and bake at 150℃ for 3 hours. Place the dried sample The porous ceramics with mullite whisker structure are obtained after debinding and sintering in a resistance furnace in a covered ceramic crucible. The specific heating program is to heat up at 3°C / min to 300°C for 1 hour, then continue to heat up at 1°C / min to 600°C for 2 hours to debinding, continue to heat up at 5°C / min to 1600°C for 2 hours, and cool down with the furnace to get the appearance Cylindrical porous mullite ceramics with needle-like struct...

Abstract

The invention discloses a novel safe alcohol lamp and a preparation method. The lamp comprises a lamp wick and a cup body made of mullite porous ceramic, wherein a matched insulating layer is disposedon the cup body; the inner wall, in contact with the cup body, of the insulating layer is coated with an isolation layer; and the outer wall of the insulating layer is coated with a teflon film. A hole structure with ultra-large porosity and full through holes of the mullite ceramic mainly used, so that the structure is used as both the lamp wick and the cup body of the alcohol lamp. In this way,the problem that after a common alcohol lamp is knocked over, alcohol can easily get splashed out from a bottle mouth or a broken glass lamp body and thus a safety accident is caused can be solved.

Description

technical field [0001] The invention belongs to the technical field of alcohol lamps, in particular to a novel safety alcohol lamp based on porous mullite ceramics. Background technique [0002] Alcohol lamp is a kind of commonly used heating equipment. The main components are glass lamp body and cotton wick. Among them, the glass lamp body plays the role of storing alcohol, and the cotton wick plays the role of diversion. This kind of alcohol lamp is easy to use, but there are also problems of overturn Alcohol is easy to spill and cause a fire hazard. Such accidents are frequently reported. For example, in 2008, the laboratory of the School of Food Science and Technology of China Agricultural University caught fire due to an alcohol lamp, and the burned area was more than 150 square meters. Another example was reported on the Internet in August 2019 in Zaozhuang, Shandong, where two girls used an alcohol lamp to cause a fire, killing one and injuring the other. Aiming at ...
