İstifadəsi üçün ehtiyat tədbirləri laboratory muffle furnaces

1. When the high-temperature muffle furnace is used for a long time or is used again after a long period of inactivity, it must be oven-baked. The oven time should be four hours at room temperature 200°C. 200°C to 600°C for four hours. When in use, the furnace temperature should not exceed the rated temperature, so as not to burn the heating element. It is forbidden to pour various liquids and easily soluble metals into the furnace. The muffle furnace works at a temperature below 50°C. At this time, the furnace wire has a longer life.

2. The muffle furnace and controller must work in a place where the relative humidity does not exceed 85%, and there is no conductive dust, explosive gas or corrosive gas. When metal materials with grease or the like need to be heated, a large amount of volatile gas will affect and corrode the surface of the electric heating element, causing it to be destroyed and shorten the life. Therefore, the heating should be prevented in time and the container should be sealed or properly opened to remove it.

3. Mufel sobasının tənzimləyicisi 0-40℃ ətraf mühitin temperaturu diapazonunda istifadə etmək üçün məhdudlaşdırılmalıdır.

4. According to the technical requirements, regularly check whether the wiring of the electric furnace and the controller is in good condition, whether the pointer of the indicator is stuck or stagnated when moving, and use the potentiometer to calibrate the meter due to magnetic steel, demagnetization, wire expansion, and shrapnel Increased error caused by fatigue, balance failure, etc.

5. Gödəkçənin partlamaması üçün termocüt yüksək temperaturda qəfildən çıxarmayın.

6. Ocaq kamerasını təmiz saxlayın və ocaqdakı oksidləri vaxtında çıxarın.
