Resin Traps and Strainers

Product Character

Widely applied in the semiconductor process for the circulation and purification of strong acid (e.g., sulfuric acid, nitric acid, hydrochloric acid) and strong alkali (e.g., potassium hydroxide, sodium hydroxide) solutions, particularly for protecting ion exchange resin beds, post-ultra-pure water preparation, and the purification of etching and CMP slurries.

  • Product Advantages
  1. Exceptional Strong Acid/Alkali Resistant Materials: The core advantage of this filtration system lies in its strong acid/alkali resistant special material construction. We select high-performance, corrosion-resistant polymers or special alloy filter media and structural components that can consistently withstand the erosion of concentrated acids, concentrated alkalis, and other corrosive chemicals over the long term, ensuring equipment reliability and filtration integrity under extreme operating conditions.
  2. Precise Slots for Ultimate Filtration Accuracy: The filter screen is designed with precise slot sizes, effectively intercepting minute resin particles, impurities, and gels from the solution, ensuring the fluid achieves the ultra-high filtration accuracy required for semiconductor processes. This is crucial for improving wafer yield and reducing defects, providing you with an impeccable chemical purification solution.
  3. Timed Backwash for Excellent Throughput Maintenance: The system innovatively integrates a timed backwash device. Through automated reverse flushing, trapped contaminants on the filter screen can be effectively removed, preventing clogging and thereby maintaining excellent throughput and stable pressure drop. This not only guarantees process continuity but also significantly reduces the frequency of manual cleaning and filter media replacement, leading to substantial operational cost savings.
  4. Protects Critical Equipment, Extends Lifespan: Effective filtration prevents tiny impurities from entering pumps, valves, precision instruments, and downstream reaction tanks or storage tanks. This significantly protects critical equipment from wear and contamination, thereby extending the overall system's lifespan and reducing costly maintenance expenses.
