Yuav ua li cas siv lub muffle rauv kom raug

1. When the muffle furnace is used for the first time or used again after a long period of inactivity, it must be oven-dried. The oven time should be four hours at room temperature 200°C. 200°C to 600°C for four hours. When in use, the maximum furnace temperature must 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 best to work below the maximum temperature of 50 ℃, when the furnace wire has a longer life.

2. Lub tshuab hluav taws xob thiab lub tshuab hluav taws xob yuav tsum ua haujlwm nyob rau hauv qhov chaw uas tus txheeb ze cov av noo tsis tshaj 85%, thiab tsis muaj plua plav conductive, roj tawg lossis roj corrosive. Thaum cov khoom siv hlau nrog roj lossis cov zoo li yuav tsum tau ua kom sov, cov pa roj ntau ntau yuav cuam tshuam thiab corrode qhov chaw ntawm cov hluav taws xob cua sov, ua rau nws raug puas tsuaj thiab ua rau lub neej luv. Yog li ntawd, cov cua sov yuav tsum tau tiv thaiv nyob rau hauv lub sij hawm thiab lub thawv yuav tsum tau muab kaw los yog qhib kom zoo kom tshem tawm nws.

3, lub muffle furnace maub los yuav tsum raug txwv rau siv nyob rau hauv qhov kub thiab txias ntawm 0-40 ℃.

4. Raws li cov kev xav tau, tsis tu ncua xyuas seb cov xaim hluav taws xob ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob yog qhov zoo, seb lub pointer ntawm qhov taw qhia tau daig lossis stagnated thaum tsiv, thiab siv lub potentiometer los ntsuas lub ntsuas ntsuas vim yog hlau nplaum hlau. , demagnetization, xaim nthuav dav, thiab shrapnel Ntau qhov yuam kev tshwm sim los ntawm kev qaug zog, sib npaug tsis ua haujlwm, thiab lwm yam.

5. Tsis txhob rub tawm lub thermocouple tam sim ntawd ntawm qhov kub siab kom tiv thaiv lub tsho los ntawm tawg.

6. Yuav tsum ua kom lub cub tawg kom huv si thiab tshem tawm cov oxides hauv qhov cub kom lub sijhawm.
