使用化学方法清除积炭是用化学溶剂与积炭发生物理、化学作用,破坏积炭的结构,使积炭逐渐松散、软化。清除积炭的溶剂配方有许多种,目前推荐以下配方:醋酸乙酯4.5%、丙酮1.5%、乙醇22%、苯40.8%、石腊1.2%、氨水30%(但是铜质零件不宜使用此配方)。对于铝合金零件,不可采用含苛性钠的化学溶剂。具体操作方法是:将积炭零件放在化学溶剂中,加热至90℃(使用上述配 The use of chemical methods to remove coke is the use of chemical solvents and coke physical and chemical effects, destruction of coke structure, the carbon gradually loose, softened. There are many solvent formulations for removing carbon deposits. The following formula is currently recommended: ethyl acetate 4.5% acetone 1.5% ethanol 22% benzene 40.8% paraffin 1.2% ammonia 30% ). For aluminum alloy parts, do not use caustic soda containing chemical solvents. The specific method of operation is: the coke parts on the chemical solvent, heated to 90 ℃ (using the above distribution
