How It Works

Nafitec® is NBC Meshtec's proprietary nanoparticle treatment process. NBC Meshtec developed Nafitec® to overcome the limitations of conventional nanocoating treatments. Quality made in Japan.

The Nafitec® process was developed to improve the performance of functional inorganic nanoparticles affixed to a broad range of material products. In particular, it has been found to greatly improve industrial particle classification when applied to sieve screens. The vastly improved deblinding ability of Nafitec®-treated screens increases throughput rates and boosts efficiency.

Polyester

Nafitec® Results

Sieve screens treated with Nafitec® offer enhanced deblinding and superior performance.

Conventional processes fix active nanoparticles within a plastic substrate and then treat a material surface with that substrate. This means that only a small portion of the active particles end up exposed on the surface and have any effect. The Nafitec® treatment process evenly fixes nanoparticles on the surface of the substrate to maximize active surface area.

Nafitec® vs. Untreated

These photos demonstrate the difference between Nafitec® screens and untreated sieve screens after sifting a variety of different powder materials. Sieve blinding is greatly reduced on Nafitec® screens throughout the process, improving efficiency and reducing maintenance time.

The improved sieve performance and reduced production costs provided by Nafitec® screens allow you to set higher production targets using just your existing sieving equipment.

Silver Powder

Vibration Sifter Test

  • Test sifter:φ300mm vibration sifter without de-blinding balls
  • Test Powder:Silver powder (Ag) , D50:3 microns
  • Mesh Type:Stainless steel wire mesh 500 mesh (/inch), mesh opening 25 microns

Toner Powder

Vibration Sifter Test

  • Test sifter:φ300mm vibration sifter without de-blinding balls
  • Test Powder:Non-magnetic toner (commercial grade) , D50:9 microns
  • Mesh Type:Polyester 230 mesh (/inch), mesh opening 65 microns

Silicon Dioxide Powder

Vibration Sifter Test

  • Test sifter:φ300mm vibration sifter without de-blinding balls
  • Test Powder:Silicon dioxide, D50:25 microns
  • Mesh Type:Nylon 230 mesh (/inch), mesh opening 67 microns

Wheat Flour

Vibration Sifter Test

This graph shows sieve throughputs of different-sized wheat flour particles over time. At finer particles sizes, like 236 microns, traditional screens experience severe blinding while the Nafitec® screen continues to perform.

  • Test sifter:250mm x 250mm sifter
  • Test Powder:Wheat flour
  • Mesh Type:Nylon mesh, mesh opening 200 microns

Nafitec® Sieve Screens

NBC Meshtec’s proprietary Nafitec® treatment can be applied to our entire range of sieve screens. Replacing conventional screens with Nafitec®-treated screens on your existing sieves not only improves your performance, it allows you to classify much finer particles than was previously possible.
