摘要： An abrasive article comprising abrasive grains, a porous support material and a resin bond including a coupling agent for coating said abrasive grains and said support material, said resin bond being adhered to the grains and support material with the aid of said coupling agent, the coupling agent being compatible with the resin bond, said resin bond yielding little or no volatiles during its curing so as to effect the bonding and being cured under conditions to limit production of volatiles so as to maintain the amount of interchannel porosity to less than 14% of the total volume of the abrasive article, the porosity of the article being essentially determined by said support material, whereby the article has dimensional stability during cure and superior resistance to impregnation with water after being cured. The support material may include hollow bodies, such as microbubbles of glass or alumina or the like, and the support material is used in an amount that is carefully controlled to produce the desired porosity in the abrasive article. A wide range of controlled porosity levels in the respective grinding wheels produced may be accomplished resulting in the production of wheels having superior wet strength and dimensional stability.
摘要翻译： 一种磨料制品，包括磨料颗粒，多孔载体材料和树脂粘合剂，其中包括用于涂覆所述磨料颗粒和所述载体材料的偶联剂，所述树脂粘合剂借助于所述偶联剂粘合到颗粒和载体材料上， 所述树脂粘合剂在其固化期间几乎不产生挥发性物质，以便在限制挥发物生产的条件下进行粘合和固化，以使通道间孔隙率保持在小于14％ 磨料制品的总体积，制品的孔隙度基本上由所述支撑材料确定，由此制品在固化期间具有尺寸稳定性，并且在固化后具有优异的耐浸渍水性。 支撑材料可以包括中空体，例如玻璃或氧化铝等的微泡，并且支撑材料的使用量被小心地控制以在磨料制品中产生所需的孔隙率。 可以实现在所生产的相应磨轮中的宽范围的受控孔隙度水平，导致具有优异的湿强度和尺寸稳定性的车轮的生产。
