    • A method for producing organically bonded abrasive article includes combining an abrasive grain component and a phenol-based resin component. The combined components are molded and thermally cured in an atmosphere that comprises humidity, wherein the atmosphere contacts the molded components, thereby producing the organically bonded abrasive grain. The abrasive grain optionally can first be combined with an organosilicon compound, to form organosilicon-treated abrasive grain, and then with the phenol-based resin component. In one example, the phenol-based resin is thermally cured in the presence of steam. Abrasive articles produced by the method of the invention generally have improved properties under wet grinding conditions. In one example, an abrasive article produced by the method of the invention includes ammonia in an amount less than about 50 ppm. In another example, an abrasive grinding wheel produced by the method of the invention has a strength retention greater than about 57 percent.
    • 一种用于制造有机粘合的磨料制品的方法包括组合磨料颗粒组分和酚基树脂组分。 组合的组分在包含湿气的气氛中被模制和热固化,其中气氛与模制部件接触,从而产生有机粘结的磨料颗粒。 磨料颗粒任选地可以首先与有机硅化合物组合,以形成有机硅处理的磨料颗粒,然后与酚基树脂组分组合。 在一个实例中,酚基树脂在蒸汽存在下热固化。 通过本发明的方法生产的磨料通常在湿磨条件下具有改进的性能。 在一个实例中,通过本发明的方法生产的磨料制品包括小于约50ppm的氨。 在另一个实例中,通过本发明的方法制造的研磨砂轮的强度保持率大于约57%。
