The cleanliness of component' surfaces will affect the reliability and durability of advanced technology products in automobile, airplane and medical industry. Chip, burr, casting sand, welding slag, abrasive and other solid particles will cause the following damages: bearing blockage, valve blockage, nozzle blockage, short circuit, cylinder leakage, pump burning, etc.
So, what is Technical Cleanliness? Why is it necessary to detect these pollutant particles? How is cleanliness (pollutant particles) quantified?
The technical cleanliness means of detecting potential pollutant particles in automotive / components. These particles can cause blockages, scratches, poor contacts, malfunctions, and other issues in fluid and electronic systems during operation. Consequently, this can lead to the entire automotive system not functioning properly, certain functions failing, paralysis, and even safety incidents. Therefore, cleanliness is a highly crucial indicator. It is quantified based on parameters such as the weight of pollutant particles, the geometric dimensions of particles, particle quantity, distribution range, properties, composition, and more.''
