Instructions for using the Nabore muffle furnace:
1. The area around the electric furnace should be free of flammable and explosive substances, corrosive gases, and other hazardous gases, and easy to heat outside the furnace.
2. Before use, check if the grounding is good. Grounding wires can be installed to ensure safe use.
3. After receiving the muffle furnace, the furnace should be dried first. When in use, the furnace should also be dried first after long-term shutdown. The time is about 4 hours and the temperature is about 200~600 ° C.
4. When taking or placing items in the furnace, the power should be disconnected first, the furnace door should be gently opened and closed, and the sample should be handled gently to avoid damaging the furnace and machine components.
5. When in use, the furnace temperature shall not exceed the upper limit temperature, and it shall not work for a long time above the rated temperature.
6. Turn off the power after use, let it cool naturally, and then remove the sample.
Precautions for using Nabore muffle furnace:
1. The surface oxide layer can ensure the service life of the heating element. If damaged, it will directly affect the service life of the heating element. However, each shutdown will damage the oxide layer to some extent, so shutdown should be avoided as much as possible after startup.
2. Do not pour liquids and dissolved metals into the furnace. When conducting ashing tests using an electric furnace, please ensure that the sample is fully carbonized before placing it in the furnace, as carbon accumulation can damage the heating element.
3. The insulation material of the thermal expansion furnace may crack after several heating cycles, but it does not affect the quality of the electric furnace.
4. When heating, the sample must be placed in a clean crucible. Be careful not to contaminate the stove. If foreign objects are found, they should be cleaned up in a timely manner.
5. Pay attention to observation during use to avoid accidents caused by failure to detect problems in a timely manner.
