For degreasing and cleaning of parts and small parts that handle a large number of parts in a cleaning basket, mainly 1,1,1-trichloroethane and CFC 113, which are non-aqueous and have excellent properties such as high degreasing power and noncombustibility The halogen-based solvent has been mainly used.

問題点がある。Further, the water-based cleaning agent has the advantage that it is not flammable, but it has a weak degreasing power and is liable to cause stains and corrosion problems on metal parts, and is accompanied by auxiliary equipment such as rinsing, drying and wastewater treatment. There are many problems such as the need for space for that.

転換せざる得ない状況にある。As described above, any of the alternative cleaning agent candidates has various problems, but there is no expectation that a desirable alternative product will be developed in the near future, and it is unavoidable to switch to any of the alternative cleaning agent candidates immediately. There is a situation.

系洗浄剤は、敬遠されがちである。The cleaning process is very important because it affects the quality and life of the final product to be cleaned, and 1,1,1-trichloroethane is often used for cleaning metal parts in small and medium-sized enterprises. Therefore, the water-based cleaning agent, which involves a lot of capital investment including expansion of the cleaning process and wastewater treatment equipment, is often shunned.

On the other hand, a sufficient liquid volume cannot be obtained, frequent liquid replacement is required, and in consideration of work efficiency and economy, distillation recovery is indispensable in order to forcibly remove the oil content mixed in the cleaning liquid.

が分かった。However, the conventional hydrocarbon-based detergents are mainly petroleum fractions or compositions in which various substances are blended, and if these are repeatedly distilled and recovered, the composition changes. It was found that the characteristics of the composition could not be maintained, causing poor cleaning of objects to be cleaned and corrosion problems.

から使用されてきた塩素系及びフロン系溶剤の代替洗浄
剤として極めて有効である。The azeotropic-like detergent composition of the present invention has a sufficient removal ability against any stains such as machine oil attached to processed parts such as equipment and flux attached to printed boards. It has, and can be repeatedly distilled and used,
Since there is no concern about environmental pollution such as ozone layer destruction, it is extremely effective as a substitute cleaning agent for the chlorine-based and CFC-based solvents that have been conventionally used.
