The cleaning method of the laser cooling box and the detection method of its cleanliness

Abstract

The invention discloses a cleaning method for a laser device cooling box and a detection method for detecting the cleanness of the cleaning method, and aims to provide a cleaning method which is convenient, precise, high in cleanness and capable of rapidly cleaning a cooling box of a complicated structure and a detection method which is simple, convenient, accurate and capable of quantificationally and precisely judging the washing cleanness. The cleaning method disclosed by the invention comprises the following steps: respectively connecting an inlet pipeline and an outlet pipeline of a water pump with a water inlet and a water outlet of a cooling water circulation loop of a cooling system of the laser device cooling box; filling pure glycol washing liquid into the laser device cooling box; subsequently putting the laser device cooling box full of the glycol washing liquid into an ultrasonic washer of which the temperature is regulated to 80 DEG C; starting the ultrasonic washer and the water pump to make sure that the glycol in the laser device cooling box can flow circularly under the effect of the water pump; performing a transmittance test on a standard glycol sample and a glycol liquid sample by using a spectrophotometer; afterwards comparing the transmittance test results of the standard glycol sample and the glycol liquid sample, wherein the cleanness is considered to be good if the sample transmittance is 2% smaller than the standard glycol transmittance.

Description

technical field [0001] The invention relates to a cleaning method of a cooling box with a complex structure and a detection method for its cleanliness, in particular to a cleaning method for a titanium alloy cooling box of a liquid-cooled laser and a detection method for its cleanliness. Background technique [0002] Metal cleaning involves not only the choice of degreaser type, but also the appropriate degreasing process and process equipment that must obtain qualified workpieces at a given rate (workpieces / hour). Simply put, the role of metal degreasing is to remove the dirt accumulated in the previous operation on the metal surface in preparation for the subsequent operation. The equation for degreasing operation can be explained as follows: process equipment + process + degreasing agent = qualified workpieces / hour. Each term in the equation plays a role in operating economically by providing acceptable workpieces at a given speed. The equation also accounts for the fac...
