Surface treatment

  • Water and oil repellent treatment: A substantial increase in performance of water and oil repellent

  • Acrylic coating: A substantial increase in Abrasion resistance property
  • Carbon coating: Anti-spark
  • PTFE film: Improve filtration precision: ≤5gsm/Nm3, but lower the filtration efficiency; and a substantial increase in acid-base resistance property
  •  PTFE paint-coating: Improve filtration precision: ≤10gsm/Nm3, does not lower the filtration efficiency; and a substantial increase in acid-base resistance property
  •  PTFE dipping: Improve filtration precision: ≤25gsm/Nm3, does not lower the filtration efficiency; and a small increase in acid-base resistance property
