摘要： A highly durable repair-coating method is provided, which permits the simple, fast, efficient and effective removal of thick rust and fixed rust generated on a steel structure having a large area such as a bridge and an intermediate iron product, under storage, which can ensure high working properties and high safety while reducing the processing cost, and which can likewise ensure high quality repairing and the subsequent improved duration of the repaired and coated articles.The method is for highly durable repair-coating of a coated or coating-free steel structure which comprises the steps of conditioning the ground of the coated or coating-free steel structure such that the rate of exposed surface area of the ground is not less than 60%; and then applying an aqueous solution of sodium carbonate having a concentration of not less than 5 g/L and not more than 500 g/L, as a prior processing solution; and further optionally applying a highly corrosion-resistant zinc powder-containing composition which comprises 100 parts by mass of a binder resin (the solid content by mass); 200 to 800 parts by mass of zinc powder; 1 to 95 parts by mass of a corrosive ion-fixing agent; and 200 to 1,000 parts by mass of a solvent.
摘要翻译： 提供了一种高度耐用的维修涂覆方法，其允许在存储下，在诸如桥梁和中间铁产品的大面积的钢结构上简单，快速，有效和有效地去除产生的厚锈和固定锈，其中 可以确保高的加工性能和高的安全性，同时降低加工成本，并且同样可以确保修复和涂覆制品的高质量修复和随后的改进的持续时间。 该方法是对涂覆或无涂层的钢结构进行高度耐久的修补涂层，其包括以下步骤：调节涂覆或无涂层的钢结构的磨碎层，使得地面的暴露表面积的比率不小于 60％; 然后将浓度不小于5g / L且不超过500g / L的碳酸钠水溶液作为先前的处理溶液; 进一步任选地使用包含100质量份粘合剂树脂（固体成分质量）的高耐腐蚀性锌粉组合物; 200〜800质量份锌粉; 1〜95质量份腐蚀性离子固定剂; 和200〜1000质量份的溶剂。

摘要： An inexpensive rotary grinding tool with reduced noise level of the grinding is provided. The rotary grinding tool comprises a metal disk having a grinding surface on at least a part of its surface and a holder for supporting the metal disk. The grinding surface has hard grains having a Mohs hardness in excess of 9 brazed thereon at a surface density of at least 20 grains/cm2. The holder has at its center a securing means for securing the holder on rotary shaft of a rotary drive unit. The holder and the metal disk are joined together to constitute the rotary grinding tool.
