Nhanganyaya kune marudzi uye zvinhu zve lightweight thermal insulation zvidhinha
Kune marudzi akawanda ezvidhinha zvisingaremi uye zvinhu. Chiedza-huremu-inodzivirira zvidhinha mukuvaka zvinogadzirwa uye zvinogadziriswa nefoam tekinoroji. Mune indasitiri yerefractory, zvidhinha zvisinganzwisisiki zvinonziwo lightweight heat-insulating refractory bricks, izvo zvisingakwanisi chete kuchengetedza simba uye kupisa uye zvinogona kushandiswa pane imwe tembiricha. Zvidhinha zvisingaremi zvakakwirira-alumina zvinozivikanwawo seyepamusoro-alumina thermal insulation zvidhinha. Iyo alumina yemukati inodarika 48%, uye ikareruka refractory inonyanya kuumbwa mullite uye girazi chikamu kana corundum. Hulk density i 0.4 ~ 1.35g/cm3. Iyo porosity i66% ~ 73%, uye iyo yekumanikidza simba i1~8MPa. Thermal shock resistance iri nani.
Zvidhinha zvisingaremi zvakakwirira-alumina zvinowanzoshandisa high-alumina bauxite clinker uye ivhu shoma, mushure mokunge yanyatsogadziriswa, inodururwa uye yakaumbwa muchimiro chedhaka nenzira yekugadzira gasi kana nzira yefuro, uye inopisa pa 1300-1500 ° C. . Dzimwe nguva maindasitiri alumina anogona kushandiswa kutsiva chikamu chebauxite clinker. Inoshandiswa kune lining uye kupisa kwekudzivirira kwemukati kwemasonry kilns, pamwe chete nezvikamu zvisina kusvibiswa uye zvakasvibiswa nezvinhu zvakasimba zvekupisa zvakanyungudutswa. Kana yakanangana nemurazvo, tembiricha yekubata pamusoro haifanire kunge yakakwira kupfuura 1350°C. Zvidhinha zvidhinha zvakareruka zvekupisa zvidhinha zvakakodzera tembiricha ye900℃~1650℃. Iyo ine hunhu hwekupisa tembiricha kuramba, kusimba kwepamusoro, kuderera kwekushisa conductivity, uye kunoshamisa kwekuchengetedza simba.
