Halaye da Amfanin Graphite

Bayanin Samfura: Graphite

Foda ta Graphite tana da laushi, launin toka baƙi, mai mai kuma tana iya gurɓata takarda. Taurinta shine 1-2, kuma tana ƙaruwa zuwa 3-5 tare da ƙaruwar ƙazanta a gefen tsaye. Matsakaicin nauyi shine 1.9-2.3. A ƙarƙashin yanayin keɓewar iskar oxygen, wurin narkewarta yana sama da 3000 ℃, wanda shine ɗayan ma'adanai mafi jure zafin jiki. A zafin ɗaki, halayen sinadarai na foda graphite suna da ƙarfi sosai, ba sa narkewa a cikin ruwa, suna rage acid, suna rage alkali da sinadarai na halitta; kayan yana da juriyar zafin jiki mai yawa da kuma juriyar aiki, kuma ana iya amfani da shi azaman kayan da ke jure wa yanayi, masu jure wa lalacewa da kuma masu shafawa.

Saboda tsarinsa na musamman, graphite yana da halaye masu zuwa: 1. Juriyar zafin jiki mai yawa: wurin narkewar graphite shine 3850 ± 50 ℃, kuma wurin tafasa shine 4250 ℃. Wato, ƙimar asarar nauyi da yawan faɗaɗa zafi suna da ƙanƙanta sosai lokacin amfani da sintering mai zafi mai zafi, kuma ƙarfin graphite yana ƙaruwa tare da ƙaruwar zafin jiki. A 2000 ℃, ƙarfin graphite yana ninka. 2. Man shafawa: man shafawa na graphite ya dogara da girman graphite. Girman sikelin shine, ƙaramin ma'aunin gogayya, kuma mafi kyawun aikin man shafawa. 3. Kwanciyar sinadarai: graphite yana da kyakkyawan kwanciyar hankali na sinadarai a zafin ɗaki, yana jure wa tsatsa mai guba ta acid, alkali da kwayoyin halitta. 4. Roba: graphite yana da ƙarfi mai kyau kuma ana iya matse shi cikin siririn zanen gado. 5. Juriyar girgizar zafi: lokacin da aka yi amfani da graphite a zafin ɗaki, yana iya jure canjin zafin jiki mai tsanani ba tare da lalacewa ba. Idan zafin ya tashi ba zato ba tsammani, ƙarar graphite ba za ta canza sosai ba kuma ba za a sami tsagewa ba.

Amfani:

1. A matsayin kayan da ke hana ruwa gudu: graphite da samfuransa suna da halaye na juriya ga zafin jiki mai yawa da ƙarfi mai yawa. Ana amfani da su galibi don kera su.graphite Cruciblea masana'antar ƙarfe, kuma ana amfani da su azaman wakili mai kariya ga ingot na ƙarfe da rufin tanderu na ƙarfe.

2. A matsayin kayan shafawa masu jure lalacewa: ana amfani da graphite a matsayin mai shafawa a masana'antar injina. Man shafawa yawanci bai dace da babban gudu, zafi mai yawa da matsin lamba mai yawa ba.

3. Graphite yana da kyakkyawan daidaiton sinadarai. Ana amfani da shi sosai a masana'antar man fetur, hydrometallurgy, samar da acid-base, zare na roba, yin takarda da sauran fannoni na masana'antu, wanda zai iya adana kayan ƙarfe da yawa.

4. Ana iya amfani da Graphite a matsayin gubar fensir, fenti da kuma wakili mai gogewa. Bayan sarrafawa ta musamman, ana iya yin graphite a matsayin kayan aiki na musamman daban-daban don amfani da sassan masana'antu masu dacewa.
