Method for judging whether cleaned components are dry or not

Abstract

The invention discloses a method for judging whether cleaned components are dry or not. The method includes the steps of firstly, selecting corresponding pH (potential of hydrogen) test paper according to acid-base properties of cleaning agents for cleaning the components; secondly, wiping the surfaces of the components with the selected pH test paper; thirdly, observing colors of the pH test paper so as to judge whether the components are dry or not. The method has the advantages that whether the cleaned components are dry or not can be judged by the aid of the method, self-inspection, checking and monitoring procedures and the like can be facilitated in production procedures, the dryness of the cleaned surfaces of the components can be guaranteed, and corrosion can be completely eradicated; the method is extremely easy to implement and extremely low in cost, the quality of products can be greatly improved, costs due to repair and quality problems and the like can be lowered, and excellent effects can be realized for follow-up working procedures such as rust prevention procedures.

Description

technical field [0001] The invention belongs to the field of parts cleaning, and in particular relates to a method for judging whether parts are dry after cleaning. Background technique [0002] The degree of drying of parts after cleaning has a great influence on the storage time of parts. If the surface of the part is not dry, it is easy to rust. At present, there is no method in the industry to detect whether the parts are dry after cleaning, so it can only be observed with the naked eye, but there are many problems in this method, such as not easy to observe, unable to record, and no quantitative indicators, etc. Therefore, it is difficult to determine whether the parts are dry after cleaning There is a general lack of management, and the corrosion of parts continues to occur continuously, causing unnecessary cost and quality problems; in addition, residual cleaning fluid (such as using water for cleaning, water is also a cleaning fluid) will affect the rust prevention ...

Rust can easily occur if the surface of the part is not dry

At present, there is no method in the industry to detect whether the parts are dry after cleaning, so it can only be observed with the naked eye, but there are many problems in this method, such as not easy to observe, unable to record, and no quantitative indicators, etc. Therefore, it is difficult to determine whether the parts are dry after cleaning There is a general lack of management, and the corrosion of parts continues to occur continuously, causing unnecessary cost and quality problems; in addition, residual cleaning fluid (such as using water for cleaning, water is also a cleaning fluid) will affect the rust prevention of subsequent parts. The process will also have an impact, for example, the anti-rust effect of applying anti-rust oil to the residual cleaning fluid will be greatly reduced
