积碳是燃油及润滑油燃烧不完全和高温氧化、分解、聚合所形成的一种黑色固体状含氧、氢、碳的化合物。它是在高温高压情况下逐渐形成的,并牢固的附着在零件表面上,质地极为坚硬。为了保证设备能正常运行,充分发挥其效益,必须定期清除机件上的积碳。由于积碳特别坚硬,与金属粘附力又强,用手工清除不仅效率低,而且也难以清除干净,倘若稍有不慎,就会损伤机件。目前较为理想的是用化学方法清除积碳。此法将机件浸泡在化学溶剂中,时间2～3小时,待积碳疏松软化后,大部分积碳便自动脱落,剩余少量残碳用毛刷、抹布擦拭即可清除干净。尔后用清水冲洗,压缩空气吹干或晾干,就可装配使用。除碳剂配方见表。在设备维修中,如果没有加温设备,可用80℃以上的热水按比例配制除碳剂,随后把机件积碳处浸入
Carbon deposits are a black, solid, oxygen-, hydrogen-, and carbon-containing compound formed by the incomplete combustion of fuel and lubricants and oxidation, decomposition and polymerization at high temperatures. It is in the case of high temperature and pressure gradually formed, and firmly attached to the surface of the parts, the texture is extremely hard. In order to ensure the normal operation of equipment, give full play to their effectiveness, we must regularly remove carbon deposits on the parts. As carbon deposition is particularly hard, strong adhesion with the metal, the manual removal is not only inefficient, but also difficult to remove clean, if the slightest mistake, it will damage the machine. It is currently ideal to remove carbon deposits chemically. This method will be mechanical immersion in the chemical solvent, the time 2 to 3 hours, to be carbon loose loose, most of the carbon will automatically fall off, leaving a small amount of residual carbon with a brush, wipe to clean. After rinse with water, compressed air drying or drying, you can assemble use. In addition to carbon formulations shown in the table. In equipment maintenance, if there is no heating equipment, hot water above 80 ℃ can be used in proportion to the preparation of carbon desiccant, then the machine carbon deposition at
