Problems solved by technology

[0003] The disadvantages of the existing cleaning process are: 1. PVD coating is carried out after cleaning in this process, the quality is unstable, the effect is not good, and the good rate is about 50-80%
2. The replacement frequency of the cleaning agent is fast, the surfactant cannot be recycled, there is sewage discharge, the sewage treatment is difficult and costly
3. Prolonged contact with cleaning agent will be harmful to the body

Embodiment Construction

[0019] The steps of the superfine cleaning process before the composite component PVD coating of the preferred embodiment are:

[0020] 1. Vacuum ultrasonic cleaning. Under the conditions of vacuum degree of -40Kpa and ultrasonic frequency of 40KHz, the workpiece is placed in an environmentally friendly cleaning agent (GCL-6015) and thrown up and down at 20-70Hz, and cleaned for 180-420s. Wetting of oil, wax, glue, etc. , emulsification, cleaning effect. Environmental cleaning agent GCL-6015, the main components are surfactants and additives. Hydrocarbon water cutting agent G-100W, the main component contains CnH 2n+2 Saturated chain hydrocarbon cleaning agent and surfactant.

[0021] 2. Spray + aeration. First place the workpiece in DI water and spray it for 90-240s, and then aerate it for 120-360s under the condition of vacuum degree of -100Kpa.

[0022] 3. Vacuum ultrasonic rinsing. Under the conditions of vacuum degree of -40Kpa and ultrasonic frequency of 40KHz, the...

Abstract

The invention discloses an ultrafine cleaning process before PVD coating of a compound component. The ultrafine cleaning process comprises the steps of vacuum ultrasonic cleaning, vacuum ultrasonic rinsing, vacuum water cutting cleaning, vacuum fluid cutting, vacuum hydrocarbon ultrasonic cleaning, slow-pulling dehydration, steam bath-washing, vacuum drying and plasma cleaning. The ultrafine cleaning process can radically clean a water cutting agent and dirt on the product surface and smudge in cracks, and contributes to guaranteeing the follow-up PVD coating quality.

Description

technical field [0001] The invention belongs to cleaning technology, in particular to a cleaning process. Background technique [0002] At present, the technological process for cleaning the surface wax, glue, oil and cracks of composite components such as ceramic components, glass components, and metal-plastic components is: ultrasonic water-based cleaning→ultrasonic pure water rinsing→ultra-high vacuum treatment→ultrasonic water-based Cleaning→ultrasonic pure water rinsing→ultra-high vacuum treatment→ultrasonic water-based cleaning→ultrasonic pure water rinsing→ultra-high vacuum treatment→ultrasonic water-based cleaning→ultrasonic pure water rinsing→vacuum drying. The cleaning agent required for cleaning is an environmentally friendly water-based cleaning agent, and its main components are surfactants, additives or DI (ionized) water. Through the emulsification, penetration, cleaning and other properties of the surfactant and the acid-base chemical reaction, the purpose o...
