辉绿岩制品是一种耐磨耐腐蚀的新型工业材料。目前这种材料已较为广泛地应用在机械、冶金、燃化等工业部门,并取得了显著的效果。辉绿岩铸石制品的主要成分为 SiO_2、FeO、Fe_2O_3和其它氧化物。硬度约等于肖氏硬度78～115;抗压强度为80公斤/毫米~2;抗弯强度为7.5公斤/毫米~2。由于这种材料硬而脆,腐蚀性强,难于切削加工。市工代会双革协作 Diabase products are a new type of abrasion and corrosion resistant industrial materials. At present, this kind of material has been widely used in the machinery, metallurgy, combustion and other industrial sectors, and achieved remarkable results. The main components of diabase cast stone products are SiO 2, FeO, Fe 2 O 3 and other oxides. Hardness is about equal to the Shore hardness 78 ~ 115; compressive strength of 80 kg / mm ~ 2; flexural strength of 7.5 kg / mm ~ 2. Because of this material hard and brittle, corrosive, difficult to cut. Municipal workers will double-leather collaboration
