Yuav ua li cas tuav lub hearth ntawm lub lab muffle rauv?

1. Thaum cov lab muffle rauv thiab cov maub los yog siv, qhov ntsuas lub zog yuav tsum tsis pub tshaj, thiab qhov kub ntawm lub cub tawg yuav tsum tsis txhob tshaj qhov ntsuas qhov ntsuas kub. Nws yog txwv tsis pub muab cov khoom ntub dej rau hauv lub qhov cub, thiab cov khoom ua haujlwm kub nrog cov dej noo siab heev yuav tsum tau qhuav ua ntej.

2. Cov pas nrig silicon-carbon yuav tsum tau muab tso rau hauv qhov chaw qhuav kom tiv thaiv lub taub hau ntawm txhuas los ntawm kev ntub dej. Thaum siv, yog tias qee cov pas nrig tau pom tias yog blazing dawb thiab qee qhov xim liab tsaus, nws qhia tau hais tias qhov kev tiv thaiv ntawm txhua tus pas nrig sib txawv, thiab nws yuav tsum tau hloov nrog tus pas nrig nrog tus nqi zoo sib xws ua ntej siv nws dua.

3. Lub chaw soj nstuam muffle rauv thiab cov maub los yuav tsum ua haujlwm nyob rau hauv qhov chaw uas cov txheeb ze av noo tsis tshaj 85%, tsis muaj cov plua plav, cov pa tawg, thiab cov roj corrosive uas tuaj yeem ua rau cov hlau rwb thaiv tsev thiab cov khoom siv hluav taws xob puas.

4. Qhov chaw ua haujlwm kub ntawm tus maub los yog txwv rau 0-50 ℃.

5. Lub chaw kuaj muffle rauv yuav tsum tau ua kom huv si. Cov hlau oxides, molten slag thiab impurities nyob rau hauv lub cub tawg yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm. Kev saib xyuas yuav tsum tau ua thaum thauj khoom thiab tshem tawm cov khoom ua haujlwm kom tsis txhob muaj kev puas tsuaj rau silicon carbide rods.

6. Cov pas nrig silicon carbide yog cov khoom siv recrystallized ntawm silicon carbide nyob rau hauv chav kuaj muffle rauv. Alkali, alkali hlau, sulfuric acid thiab boron tebchaw tuaj yeem corrode nws ntawm qhov kub thiab txias, thiab dej vapor muaj zog oxidative nyhuv rau nws: hydrogen thiab Gases uas muaj ntau hydrogen yuav decompose silicon carbide rods ntawm qhov kub thiab txias, yog li ceev faj yuav tsum tau ceev faj. them thaum siv lawv.
