Industrial X-ray Film L7

The film is designed in accordance with advanced standard. A series of new materials and technology be used from emulsion-making to coating. It is an ideal film for industrial non-destructive inspection photographing.

FEATURES AND USAGES

The industrial x-ray film L7 is double coated on bluish polyester base. It is high speed with small grain and high contrast. It has perfect ability to find the defect exactly because of its excellent structure of emulsion-grain and coating-layer. It is widely used in NDT x-ray inspection for parts, components, shaped materials or welding seams made of ferrous, non-ferrous metals and their alloys or other materials with low attenuation coefficient.

SAFE ILLUMINATION

This film can be processed and inspected under dark red safelight filter of Kodak No-2 or other equivalent filters with transmitting range over 630nm. A 15W safe-lamp should keep 1.2 meter away for the film.

PROCESSING

SIZE AND PACKAGE

Note: It can be available in other sizes and quantities of packing on request.

STORAGE

Unexposed film should be kept in original packages and stored in places where should be clean, no dust, free from ammonia, hydro sulfuric gases and penetrating radiation. The film is adversely affected by heart and humidity. The recommendatory storage temperature is bellow 21°C and humidity bellow 65%RH. For unsealed film, the ideal humidity is from 30%-50%RH. The film packages should be placed on edge to avoid pressure marking the film.

The film storied at low temperature should be conditioned at room temperature for more than 4 hours before opening the package for using in order to prevent condensation on film surface and degradation of the film.
