Ceramic Muffle furnace is a kind of furnace with ceramic material as heating element. It usually consists of an integrated ceramic furnace and a ceramic burner. Ceramic furnace can provide excellent thermal stability and high temperature resistance, so that the Muffle furnace can work in a high temperature environment, and can maintain a stable heating effect for a long time, below we take a look at the use of ceramic fiber Muffle furnace "12" precautions

1. Place it on a horizontal cement platform with a flat surface, do not store chemical reagents and flammable and explosive materials around it, and pay attention to good insulation of the equipment.

2. Do not exceed the maximum temperature of the ceramic fiber Muffle furnace when used.

3. Use a special switch to control the power supply. When using the ceramic fiber Muffle furnace, find out whether the power supply voltage, power, configuration power, fuse, switch, etc. match the current, voltage, and rated power, and connect the ground wire.

4. When burning or melting in the furnace, it is necessary to control the heating rate and maximum temperature according to the operating conditions of the sample to prevent the sample from spatter, corrosion or adhesion to the furnace. If burning organic matter, filter paper, etc., must be pre-carbonized.

5. When the ceramic fiber Muffle furnace is used, the power supply should be disconnected after burning, and the furnace door should not be opened immediately to prevent acute cooling. Usually when used, you can first open a gap to speed up the cooling, when the temperature drops to about 200 ° C, open the furnace door and remove the burned object with a long-handled crucible pliers.

6. When the new ceramic fiber Muffle furnace is used, it should be baked at low temperature for several hours to effectively prevent rapid temperature changes and protect the furnace and equipment. Generally, the furnace is equipped with a fire-resistant backing plate, which can effectively prevent occasional splashing and effectively protect the ceramic fiber furnace.

7. It is forbidden to pour any liquid into the furnace, clean the furnace frequently, and remove the residual oxide in the furnace in time.

8. Do not put the sample stained with water and oil into the furnace, and do not use the clip stained with water and oil to collect the sample.

9. Do not suddenly pull out the thermocouple when the ceramic fiber Muffle furnace is at high temperature to prevent the jacket from exploding.

10. Wear special protective gloves and protective gear when loading samples to prevent burns. The sample should be placed neatly in the middle of the furnace, handled gently to avoid the collision between the sample and the furnace, and the furnace door should be opened lightly to prevent damage to the ceramic fiber furnace body.

11. Working environment conditions: temperature 0~50℃, relative humidity <80%, no conductive dust, no inflammable and explosive materials and corrosive gases.

12. Ceramic fiber Muffle furnace, as a high-temperature heating equipment, needs to be taken care of often when used, and the temperature and time are set in strict accordance with the experimental requirements. The heating and cooling of the equipment should be carried out slowly and used within the normal temperature range.
