三、石墨粉價格多少錢一噸
石墨粉是一種礦物粉末,主要成分為碳單質,質軟,黑灰色,常溫下化學性質穩定,不溶于水、稀酸、稀堿和有機溶劑,具有耐高溫導電性能,可用作耐火材料、導電材料、潤滑材料、高溫冶金材料、磨光劑和防銹劑等,是一種應用廣泛的化工原料。石墨粉的種類眾多,不同種類的石墨粉用途不同,價格也有所不同,具體價格并不是統一的,要看石墨粉的含碳量、粒度等參數要求,一般市面上的石墨粉在一千多元每噸到幾萬元每噸甚至幾十萬元每噸都有。購買石墨粉時,可以通過看外觀、將石墨粉放入水中、煅燒石墨粉等方法來判斷石墨粉的質量好壞。如果您需要購買石墨粉,可以先來了解一下石墨十大品牌。
四、石墨電極的用途和性能
石(shi)(shi)墨電(dian)(dian)極(ji)是一種耐(nai)高(gao)溫石(shi)(shi)墨質導(dao)(dao)電(dian)(dian)材(cai)料(liao),是在(zai)電(dian)(dian)弧(hu)爐(lu)中以電(dian)(dian)弧(hu)形式釋放電(dian)(dian)能對(dui)爐(lu)料(liao)進(jin)行(xing)(xing)加熱(re)熔化(hua)的(de)導(dao)(dao)體,它主(zhu)要用于電(dian)(dian)弧(hu)煉鋼爐(lu)、礦熱(re)電(dian)(dian)爐(lu)、電(dian)(dian)阻爐(lu)等領域,利(li)用石(shi)(shi)墨電(dian)(dian)極(ji)向(xiang)爐(lu)內導(dao)(dao)入電(dian)(dian)流,利(li)用電(dian)(dian)極(ji)端(duan)部和(he)爐(lu)料(liao)之間引發電(dian)(dian)弧(hu)所產(chan)生的(de)高(gao)溫熱(re)源來進(jin)行(xing)(xing)冶(ye)煉,還可以用來制備異型石(shi)(shi)墨產(chan)品。石(shi)(shi)墨電(dian)(dian)極(ji)具有較強的(de)導(dao)(dao)電(dian)(dian)性(xing)、導(dao)(dao)熱(re)性(xing),較高(gao)的(de)抗(kang)熱(re)振性(xing)能和(he)化(hua)學穩定性(xing)能,良好(hao)的(de)潤滑性(xing)和(he)抗(kang)磨(mo)性(xing),且加工較容易、比重小、加工速度快,因此(ci)應用廣泛(fan)。
