Method No. 405B:去除严重腐蚀、硬碳、油漆和氧化皮
Remove heavy corrosion, hard carbon, paint and scale from steel parts as follows:
按如下方法去除钢零件上的严重腐蚀、硬质碳、油漆和氧化皮：
(1) Mask any surface that might be damaged by abrasive blasting.
遮盖任何可能被喷砂损坏的表面。
(2) Place part in a standard sandblast cabinet.
将零件放入标准喷砂柜中。
WARNING: KEEP SANDBLAST NOZZLE IN MOTION TO PREVENT BLAST FROM DWELLING ON ONE SPOT.
警告：保持喷砂喷嘴运动，以防止喷砂停留在一个点上。
(3) Set equipment air pressure at 15 to 30 psig (103.4 to 206.8 kPa).
将设备气压设置为15至30 psig（103.4至206.8 kPa）。
NOTE: Air pressure can be reduced as required to control action on base metal of part.
注：可根据需要降低气压，以控制对零件基体金属的作用。
(4) Sandblast only the specified surfaces. Refer to applicable manual. Use sand blast media C04-0038.
喷砂仅作用于规定的表面。请参阅适用手册。使用喷砂介质C04-0038。
(5) Remove part from sandblast cabinet.
从喷砂柜中取出零件。
(6) Clean the part. Refer to SECTION II – CLEANING.
清洁部件。请参阅第II节-清洁。
(7) Visually check blasted surfaces finish to be uniform.
目视检查喷砂处理的表面处理是否均匀。
(8) Apply a uniform layer of corrosion-preventive compound C02-0005.
均匀涂抹一层防腐化合物C02-0005。
