Fine-grained X-ray film Tasma PT-K is designed for radiographic inspection of welded and brazed joints, pipes of small diameter, cast products using X-ray, gamma radiation and bremsstrahlung of electron accelerators.
X-ray film Tasma PT-K has a polyethylene terephthalate base dyed in bulk in blue with a thickness of 175±10 microns according to TU 6-41-1576-93 or an imported base that meets the requirements of TU 6-14-1576-93.
Package
As a packaging material, a light-protective and moisture-proof plastic bag is used, which is inert to photographic layers. Each sheet of film is lined with white paper on both sides.
Dimensions
- 30x40 cm, 75 sheets per box;
- 24x30 cm, 100 sheets per box.
Storage
Unexposed X-ray film should be stored in a consumer container on racks in a ventilated room at a temperature of 14°C to 22°C and a relative humidity of 50% to 70%, where gases harmful to the film should not penetrate. It is not allowed to store the film in rooms where radioactive substances and luminous compositions of permanent action are located.
Treatment
X-ray film Tasma PT-K is designed for manual and machine processing.
Opening of the package and chemical-photographic processing of the film should be carried out under non-actinic lighting created by a laboratory lamp with a 15-25 W electric lamp shielded with a protective dark red light filter No. 107 according to TU 6-43-00205133-03-91.
Recommended solutions for manual processing:
developer "X-ray-2" and fixer BKF-2;
in solutions of chemical reagents "TRT-301", "X-ray-2T", TRTk.
Development time 4 - 8 min. / (20.0 ± 0.5) ° С.
Fixing no more than 15 min./(20.0 ± 2.0)°С.
It is allowed to carry out chemical-photographic processing of the film in tanks at an elevated temperature of the developer, development time:
- 4-6 min./(22.0 ± 0.5) °С,
- 4-5 min./(24.0 ± 0.5) °С,
- 3-4 min./(26.0 ± 0.5) °С,
- 2-3 min./(28.0 ± 0.5) °С.
Fixing at a temperature of 21.5°C to 28.5°C.
Recommended solutions for machine processing:
PT-K film can be processed in automatic processors according to their instructions, using domestic processing solution kits.
Distinctive features
- Fine-grained structure allows to reveal the smallest defects.
- High contrast makes it easier to decipher pictures.
