Features and uses
Industrial X-ray film is a kind of high resolution and high image
resolution film which is widely used in nondestructive flaw
detection. The film has high sensitivity, high contrast, high
definition,
It can be directly or with lead sensitization screen for X or γ ray
exposure. It is suitable for electronic components, synthetic
materials, casting and casting, welding, etc.
NDT testing for shipbuilding, national defense and nuclear
industry, aerospace and aviation industry, etc. Using blue
polyester sheet base, two sides coated with emulsion layer, layer
and
Protective layer. This film has rich layers, high image resolution
and good definition. This film can be processed at room
temperature, also can be processed by high temperature machine.

Safety lighting and washing processing
The safety operating light in the darkroom of this film is a
crimson safety light with a 15W bulb. When the film is used for
unsealing, the lamp distance is generally above 1.2 meters.
Cumulative illumination time
No more than 40 minutes. The exposed sample should be flushed
within 2h. The washing process is shown in the table below.

Matters needing attention
1. The film stored at low temperature should be taken out 2 hours
in advance before use, and placed at room temperature for more than
2 hours to ensure the temperature of the film and the use
environment
The temperature balance is consistent, and then open the film
packaging, in order to avoid the formation of water vapor on the
surface of the film caused by the adhesion between the films and
affect the film picture effect,
To ensure the normal use of film.
2. The film should be unsealed, loaded and rinsed under the safety
lamp. The film should not be exposed for too long under the safety
lamp
Contaminated film, film should be handled with care to avoid
friction. After unsealing, the film should be used up as soon as
possible, and the unused film should be sealed according to the
original package.
