土状石墨

作者:admin发布时间:2019-07-08 17:02



土状石墨也叫无定形石墨,变质程度深属优质微晶石墨,绝大部分为石墨碳,颜色刚灰,有金属光泽,质软,莫氏硬度1-2,比重2-2.24,化学性质稳定,不受强酸碱影响,土状石墨有害杂质少,铁,硫,磷,氮,钼,氢含量低。
土状石墨按其产出形态可分为两种:分散状土状石墨矿石和致密块状土状石墨矿石。土状石墨广泛用于铸造涂料,油田钻井,电池炭棒、钢铁、铸造材料、耐火材料、染料、燃料、电极糊、以及用作铅笔、焊条、电池、石墨乳剂、脱硫剂、防腐剂防滑剂、冶炼增碳剂、注锭保护渣、石墨轴承等产品的配料.
 amorphous graphite.,The degree of deterioration belongs to high-quality microcrystalline graphite. Most of them are graphite carbon, color rigid ash, metallic luster, soft, Mohs hardness 1-2, specific gravity 2-2.24. Their chemical properties are stable and not affected by strong acid and alkali. Soil graphite has less harmful impurities, and low contents of iron, sulfur, phosphorus, nitrogen, molybdenum and hydrogen.
Soil graphite can be divided into two types according to its output form: dispersed soil graphite ore and dense massive soil graphite ore. Soil graphite is widely used in foundry coatings, oil field drilling, battery carbon rods, iron and steel, foundry materials, refractories, dyes, fuels, electrode pastes, and as ingredients for pencils, welding rods, batteries, graphite emulsions, desulfurizers, preservatives, antiskid agents, smelting carburetors, ingot flux, graphite bearings and other products.
