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.
