Static Control and Web Cleaning
What type and how many particles are on your web?
Leveraging particle removal technology to identify particles by quantity, size and type to enable root cause analysis and potential for avoidance.
P
article Removal Technology, also known as Contact Cleaning, has been adopted by many OEMs and End Users to permanently remove unwanted particles from the surface of a web during critical processing, such as printing, coating and slitting. The result is a cleaner web, leading to reduced scrap and downtime and, ultimately, increased productivity and profi tability. For manufacturers seeking a deeper understanding of particle contamination, analysis can also play a critical role in delivering further improvement. In response a Particle Deposition Monitor (PDM) can empower users to assess particle contamination with high precision. The PDM enables users to identify the size, quantity and type of particles deposited on surfaces, supporting a precise approach to root cause analysis and proactive contamination management.
The PDM, developed by SAC in The Netherlands, and currently undergoing further enhancement in joint co-operation with KSM, operates by collecting particles on specialised glass Witness Plates, which are then analysed to determine particle deposition rates, providing valuable data on the types and quantities of
particles present, helping customers to identify potential sources of contamination between 5-12000 microns. If a process is known to be negatively impacted by particles 50+ microns in size, the KSM RollDrive portable cleaning station can be used to collect particles from the environment and the PDM can be confi gured
to focus on this particle size range, producing a targeted report for enhanced control over contamination sources.
For companies facing production or quality challenges, identifying the exact size and type of particles that contribute to such issues can provide quality management with a starting point for installing a protocol to analyse contamination sources. By knowing where and how to intervene, customers can avoid introducing problematic particles into the process altogether. Additionally, this detailed insight enables customers to engage in constructive dialogue with raw material suppliers to assess incoming quality and strengthen their supplier relationships.
