no. 1 approach

[0084] figure 1 The washing and regenerating device 1 of the first embodiment is shown. The cleaning and regenerating device 1 is equipped with a cleaning mechanism 2 that uses an industrial azeotropic cleaning agent 4 to clean articles with industrial dirt attached, and regenerates the waste liquid of the industrial azeotropic cleaning agent 4 used in cleaning the articles in the cleaning mechanism 2. The regenerative mechanism3.

[0085] The cleaning mechanism 2 carries out ultrasonic cleaning, and is equipped with a first liquid tank 21A, a second liquid tank 21B, and a third liquid tank 21C for storing an industrial azeotropic cleaning agent 4, and is arranged on the bottom of each liquid tank 21A, 21B, and 21C. The ultrasonic vibrators 22 that irradiate ultrasonic waves are applied to the insides of the liquid tanks 21A, 21B, and 21C. Any known vibrator, such as a piezoelectric element or an electromagnetic vibrator, can be used as the ultrasonic vibrator 22 . In the f...

Abstract

The objective of the present invention is to provide a glycol-based cleaning agent for industrial use, which has excellent ability of removing various kinds of industrial dirt such as solder pastes, flux residues and various oils adhering to articles, while having no flash point and being recyclable (recyclable by distillation) at atmospheric pressure. The present invention relates to a recyclable azeotropic cleaning agent for industrial use, which is characterized by containing an azeotropic mixture that contains (A) a glycol-based solvent represented by general formula (1) R1-O-[-CH2-CH(X)-O]n-R2 (wherein each of R1 and R2 represents an alkyl group having 1-3 carbon atoms, n represents 2 or 3, and X represents a hydrogen atom or a methyl group) and having a boiling point of 160-230 DEG C at atmospheric pressure, (B) water, and if necessary, (C) a tertiary amine having a boiling point of 160-230 DEG C at atmospheric pressure. This recyclable azeotropic cleaning agent for industrial use is also characterized in that: the azeotropic mixture contains the component (A), the component (B) and the component (C) respectively in an amount of 5-35 wt%, in an amount of 65-95 wt% and in an amount of 0-30 wt%; and the azeotropic mixture has an azeotropic point of 90-100 DEG C at atmospheric pressure.

Description

technical field [0001] The invention relates to a recyclable industrial azeotropic cleaning agent, a method for cleaning articles, a regeneration method for an industrial azeotropic cleaning agent, an industrial azeotropic cleaning agent regenerated by the regeneration method, and a method for cleaning and industrial cleaning of articles. Clean the regeneration unit with the regeneration of the azeotropic cleaning agent. Background technique [0002] Industrial cleaning agents are used to improve the reliability of products by cleaning the surfaces of various items such as electrical equipment, electronic parts, precision equipment, metals, glass, ceramics, and resin molded products. [0003] Among the cleaning agents for industrial use, for example, cleaning agents for flux residues are used to remove flux residues inevitably generated after bonding electronic components to electrodes of printed wiring boards using solder paste, filamentary solder, and the like. [0004] A...
