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.
| Flush the way | Other countries | Temperature / ℃ | Development time /min | Fixed time /min | Dry / ℃ | transshipment ml/m2 |
| Manual | D-19b | 20±0.5 | 5±1 | 10 | Natural drying | 300 |

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.
