长航工农兵船厂在修理“东方红407”号轮时,使用环氧粘结剂修复了腐蚀穿孔的铸铁螺旋桨叶片。该轮在进厂修理时,两只螺旋桨的六爿叶片均有大面积(达200×300毫米)的空泡腐蚀,其中四爿叶片有腐蚀穿孔,最大穿孔面积达60×100毫米,此外,还有多处直径在30～40毫米的小面积穿孔。使用环氧粘结剂修补,仅需3～4个人工,100元左右费用。修复后的螺旋桨,经二年多的航行实践,证明性能良好,由于表面涂有光洁度较高的环氧树脂层,船的航速甚至比原来还快。
Long service workers and peasant shipyard repaired the “Dongfanghong 407” round, the use of epoxy adhesive to repair the corrosion of perforated cast iron propeller blades. The round of repairs into the factory, the two propeller Liuqi leaves have a large area (up to 200 × 300 mm) cavitation erosion, of which four leaves have corrosion perforation, the maximum perforation area of 60 × 100 mm, in addition, There are many small diameter holes in the 30 ~ 40 mm perforation. Use epoxy adhesive repair, only 3 to 4 artificial, about 100 costs. After the repair of the propeller, after more than two years of sailing practice, proved good performance, due to the surface coated with a high finish epoxy layer, the ship’s speed even faster than the original.
