德国诺德泰特的电成形公司开发了一种镀镍的纤维增强的塑料轧辊,据称该轧辊具有相当于钢的强度,而其重量仅是钢的十分之一。轻量型轧辊可使工作速度提高,耗能量降低,并减少轴承的负荷。 厚度为0.3mm(0.01英寸)和1.2mm(0.05英寸)之间的镀镍层镀履在塑料基底上,然后进行机加工使精整表面达到光滑程度。这种镀锌层还可用镍-硅碳化物复合材料进一步涂履以增加抗磨损性能。 电成形公司已采用辊径达250mm(9.8
Electroforming GmbH, Nordland, Germany, has developed a nickel-plated, fiber-reinforced plastic roll that is said to have a strength equivalent to that of steel and weigh only one tenth of that of steel. Lightweight rollers increase operating speed, reduce energy consumption and reduce bearing loads. A nickel-plated layer with a thickness of between 0.3 mm (0.01 inch) and 1.2 mm (0.05 inch) is plated on a plastic substrate and then machined to smooth the finished surface. This zinc coating can be further coated with a nickel-silicon carbide composite to increase wear resistance. Electric forming company has adopted a diameter of 250mm (9.8
