Tham txog kev daws cov impurities generated nyob rau hauv lub kub yaj nplaum nplaum

Impurities tej zaum generated thaum lub sij hawm tsim khoomkub yaj nplaumdaim kab xev. Cov impurities ntawm kub-melt nplaum daim kab xev cuam tshuam rau kev siv cov nyhuv ntawm kub-melt nplaum daim kab xev. Yog li dab tsi yog vim li cas rau impurity ntawm kub-melt nplaum daim kab xev?

 

impurities tshwm nyob rau hauv cov kua nplaum lag: ib qho yog tias qhov kub thiab txias dhau mus ntev, thiab cov kua nplaum yuav raug carbonized los ua impurities; thiab lwm qhov yog tias cov kua nplaum kub yaj uas tsis tau tev tawm ntawm daim ntawv nplaum (tso ntawv) yog nchuav rau hauv cov kua nplaum. Ua los ntawm carbonization thiab blackening. Hauv thawj kis, peb yuav tsum kho qhov kub ntawm lub sijhawm, thiab qhov kub ntawm cov kua nplaum yuav tsum tsis pub tshaj 200 degrees. Lub vib nas this yuav ua li cas kom tshem tawm cov kua nplaum kub, tev tawm cov ntawv tso tawm thiab ntxuav nws ua ntej muab tso rau hauv lub tank kua nplaum.
