Why Polyurethane Screen Edge Leakage Occurs: Insights into Causes & Solutions

Why Polyurethane Screen Edge Leakage Occurs: Insights into Causes & Solutions‌

In the realm of industrial screening, polyurethane screen edge leakage poses a significant threat to production efficiency and product quality. This issue not only leads to the rejection of unqualified materials but also necessitates costly re-screening processes, ultimately tarnishing a company's reputation. By delving into the core factors behind this problem, companies can adopt preventive measures to safeguard their screening performance.

‌Primary Causes of Polyurethane Screen Edge Leakage‌

1. ‌Substandard Screen Quality‌

   • Poor material quality or manufacturing flaws can expedite wear and tear, resulting in premature leakage.
   • Inferior screens often exhibit reduced screening accuracy and a heightened risk of edge leakage.

2. ‌Improper Installation Techniques‌

   • Many screening companies underestimate the importance of correct installation methods, relying solely on experience.
   • Common installation mistakes include forcefully removing old screens (causing frame damage and uneven tension), neglecting to clean the screen frame and surface (leading to poor sealing), and improper tensioning (creating weak spots prone to leakage).

3. ‌Lack of Maintenance‌

   • Regular maintenance is vital in preventing edge leakage.
   • Neglecting inspections for wear and tear, re-tensioning loose bolts, and cleaning debris can exacerbate the issue.

‌

Addressing the Challenges: Correct Installation Practices‌

To avoid installation-related issues, follow these steps:

• Carefully remove old screens without damaging the frame.
• Thoroughly clean the frame surface and edges to ensure a tight seal.
• Place the new screen evenly, ensuring full contact with the frame.
• Gradually tighten tension plates and bolts to maintain uniform pressure across the screen.

‌Ensuring Quality: Choosing Reliable Screens‌

The quality of polyurethane screens plays a crucial role in preventing edge leakage. To mitigate risks:

• Purchase screens from reputable manufacturers known for their durability and performance.
• Avoid low-cost alternatives that compromise on material quality and craftsmanship.

‌Maintenance Matters: Key Steps to Prevent Leakage‌

Regular maintenance is indispensable in extending the lifespan of polyurethane screens and preventing edge leakage. Implement these practices:

• Inspect screens regularly for signs of wear and tear.
• Re-tension loose bolts to maintain optimal tension.
• Clean debris from the screen surface to prevent clogging and ensure smooth operation.
