What are the precautions for the muffle vira?

1. When the muffle furnace is used or used again after a long period of inactivity, the furnace must be 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 is better to work at a temperature below 50 ℃ below the high temperature, at which time the furnace wire has a longer life.

2. Iyo muffle furnace uye controller inofanira kushanda munzvimbo iyo hunyoro husingapfuuri 85%, uye hapana guruva rinoita, gasi rinoputika kana gasi rinoparadza. Kana iyo simbi yesimbi ine girisi kana yakafanana inoda kupiswa, huwandu hukuru hwegasi hunoputika huchakanganisa uye hunokanganisa pamusoro peiyo yemagetsi kupisa chinhu, zvichiita kuti iparadzwe uye kupfupisa hupenyu. Naizvozvo, kupisa kunofanirwa kudzivirirwa nenguva uye mudziyo unofanirwa kuvharwa kana kuvhurwa zvakanaka kuti ubvise.

3. The muffle furnace controller should be limited to use within the ambient temperature range of 0-40℃.

4. According to 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 verify the meter due to magnet, demagnetization, wire expansion, and shrapnel Increased error caused by fatigue, balance failure, etc.

5. Usabudisa thermocouple pakarepo pakupisa kwepamusoro kudzivirira jekete kubva pakuputika.

6. Always keep the muffle furnace clean and remove oxides in the furnace in time.
