Nafitec® test sieve

Test sieve with functional inorganic nanoparticle immobilization technology and Nafitec®.

In the unprocessed photo, the black specimen remains on the screen, causing clogging, but not on the Nafitec® sieve screen.
You can see that the sample has been screened firmly.

Since nanoparticles are very small compared to powder, the contact point when powder adheres to the surface of Nafitec® composed of nanoparticles can be made extremely small. This is thought to make it difficult for the powder to adhere, and greatly contributes to the prevention of clogging and the improvement of the screening efficiency.

Nafitec® is coated with a choice of three types, taking into account the properties of the powder you use. Therefore, it is necessary to make arrangements and sample tests in advance. Please note.

Ultrasonic cleaning machine by ultrasonic sweep vibration

When ultrasonic vibration propagates in the liquid, cavitation occurs in the liquid.
When the cavitation bubbles come into contact with the workpiece, the bubbles burst and the energy is removed to remove dirt and deposits, and ultrasonic cleaning is performed.

1. It is not a large ultrasonic cleaning agent, but it can be ultrasonically cleaned by bringing a handy type ultrasonic vibration plate close to the surface of the sieve net in a flowing water environment. There is no need for a large cleaning agent, and it is possible to generate sweep vibration with high cleaning ability locally.

2. The area around the cleaning plate is the most vibrant and the cavitation rate is high, so the powerful cleaning effect necessary to remove clogged dirt on the sieve screen can be obtained.


MINOX air jet sieving particle sizer

Model: MLS200

◆ Principle
Particles smaller than an arbitrary sieve are forcibly sucked by the negative pressure of the vacuum cleaner, and the suction air from the outside serves as the cleaning air for the sieve to prevent clogging and enhance the dispersion effect. By using this air jet effect, particles that were difficult to screen can be quickly screened to a minimum of 20μm.

◆ Features
・ Since a special JIS standard sieve (φ200mm) can be screened to a minimum of 20μm
・ Measurement time is as fast as 1.5-2 minutes
・ There is also a fine powder collecting cyclone as an option.

◆ Specifications
Material: Aluminum / Stainless
Built-in products: Timer, differential pressure gauge
Power supply: 100V 50 / 60㎐ 10Am
Accessories: Acrylic lid, vacuum cleaner (1kw 100V)
