PHOTOIONIZER

+886-2-8772-8910

FEATURES
No air flow
The soft X-ray exposure volume is equal to the ion generation volume.
Ion generation constantly occurs over the entire volume exposed to soft X-rays.
Ions generated near the charged object serve to effectively remove the electrostatic charge, so there is no need for sending generated ions toward the object by an air flow. The PhotoIonizer also removes electrostatic charges from lightweight parts and powder.
 
High ion density
Ions are generated over the entire exposed area.
In the corona discharge method, ions are mainly generated only near the electrodes. In the soft Xray method, however, ions are generated over the entire volume exposed to these soft X-rays, yielding a drastic improvement in the removal of electrostatic charges.
 
No cleaning of electrodes required
The soft X-ray method is greatly superior to the conventional discharge method.
Corona discharge ionizers require frequent cleaning of the discharge electrodes since they become contaminated due to dust adhering to them and so reduce the effect of neutralizing static electricity.
PhotoIonizers, in contrast, require no maintenance at all and ensure the excellent effect of removing static electricity over a long period of time.
 
No ozone generation
The soft X-ray method does not emit UV radiation.
Ozone is generated when the air is exposed to specific types of UV rays (approx. 10 eV). The blue light of a corona discharge contains this type of UV ray. The PhotoIonizer, in contrast, emits soft X-rays into the air to make an ionization. This ion generation method does not generate any ozone.
 
No dust particles and electromagnetic noise generation
The soft X-ray method is greatly superior to the conventional discharge method.
In the corona discharge method, microparticles in the air are attracted to the electrodes and then diffuse back as dust particles.
Corona discharge accompanies the generation of electromagnetic noise.
As long as the discharge method is used, the above problems are inevitable. In contrast, the soft X-ray method used by the PhotoIonizer eliminates these problems.
 
SOLUTIONS
A new era of safe and clean electrostatic removal has now begun.
The PhotoIonizer has solved problems such as "generation of ozone and dust particles" and "overshoot due to poor ion balance" that often occur in the conventional method.
The PhotoIonizer can also remove accumulated static charges even on high-speed moving objectsand powders, which have been impossible up until now, by using the corona discharge method.
Here are some problem solutions delivered by the PhotoIonizer - the advanced electrostatic remover.
 
IC/LCD/PDP process lines
Problem
On the IC, LCD and PDP process lines in a clean room, electrostatic charge may cause serious problem such as dust adhesion, dielectric breakdown and
corrosion from ozone on peripheral equipment.
Solution
The soft X-ray method does not cause diffusion of dust particles and provides a good ion balance that allows efficient removal of electrostatic charges without
overshoot. Since this method generates no ozone, the electrostatic removal process is kept clean and safe.
 

 

Large size glasses

Problem
Electrostatic charges cause problems such as dust adhesion during the manufacturing process in clean room environments. If large size glasses are electrostatically charged, removing the electrostatic charges from them takes a great deal of time.
Solution
In the soft X-ray method, ions are generated over the entire area exposed to X-rays so electrostatic charges can be quickly removed even from large glass surfaces.
High-speed moving objects (films, printed matters, etc.)
Problem
In film manufacturing and offset printing processes which usually move at high speed, electrostatic charges accumulated on the transfer cylinders may result
in non-uniform printing or cause electric shocks to the human body.
Solution
In the soft X-ray method, ions generated near the film surface serve to efficiently remove the electrostatic charges. Even though the film moves at high speed,
the electrostatic charges can be reliably neutralized.
In addition, ions generated by soft X-rays penetrating through the film, also neutralize the electrostatic charges on the reverse side of the film, so that the electrostatic removal effect is greatly improved.
