How It Works

Fixation & Recovery Mechanism

IAS-SDC-50 uses a water-dispersed high-molecular-weight polymer system with chelating agent enhancement to immobilize and extract radionuclides from contaminated surfaces.

01

Spray Application

The aqueous emulsion is applied by standard radioactive decontamination spray vehicle at a coverage rate of 0.6–2.5 m²/L. The homogeneous formulation ensures no nozzle clogging. On contact, the liquid immediately penetrates the surface layer and begins fixating airborne radioactive dust particles.

02

Radionuclide Sequestration via Chelation

As the film forms, specific functional groups on the polymer chains — combined with the chelating additive — create physical-chemical bonds with radioactive nuclides including organic radioiodine (131I) and noble gas species. Radionuclides are drawn from the substrate surface into the forming film matrix, preventing re-suspension and lateral migration.

03

Film Cure (≤2 hours at 25°C)

The polymer network cross-links naturally at ambient temperature. Film formation is complete within 2 hours; surface is dry-to-touch within 4 hours. The cured film achieves tensile strength ≥2.0 MPa and tear strength ≥10 kN/m, enabling clean mechanical recovery without film fracture on smooth, hard surfaces.

04

Mechanical Peel Recovery

Within the 8-hour continuous peel window, the film is recovered using a film recovery vehicle. The peel force from the substrate is ≤1 N, ensuring clean separation without substrate damage. Radionuclides remain encapsulated within the recovered film, eliminating secondary contamination. The film maintains mechanical integrity for ≥2 months, allowing deferred recovery if needed.

05

Repeat Application for High-Contamination Zones

In areas with high radionuclide loading, multiple sequential applications achieve a cumulative surface decontamination factor ≥95%. Each cycle removes an additional fraction of residual surface contamination. The coating also provides temporary shielding against α/β radiation penetration during the peel window.

Advantages

Key Performance Advantages

🌿

Non-Toxic · Zero Secondary Contamination

Water-based formulation with no hazardous solvents. Radionuclides are encapsulated within the recovered film — zero dispersal to surrounding environment.

⚗️

Chelating Agent Enhancement

Chelating additives create selective high-affinity bonds with radioactive metallic cations, significantly increasing nuclide uptake efficiency versus non-chelated film systems.

🔧

Mechanized Recovery — No Manual Peeling

Film tensile and tear strength are specifically engineered to resist breaking during roll-up by film recovery vehicles on flat or paved surfaces. Continuous film sheets = no fragment contamination.

📏

Adjustable Coating Depth

Application thickness is operator-controlled. Increase coating depth for α emitters (which require greater film mass for self-shielding); reduce for β/γ-dominated contamination scenarios.

🌡️

Wide Temperature Operability

Application window 5°C–40°C (41°F–104°F). Long-term use from –10°C to +50°C (14°F to 122°F). No performance degradation across the operational range.

🚛

Equipment-Friendly Formulation

Homogeneous emulsion state eliminates spray nozzle clogging. Non-corrosive to metals, rubbers, and polymers used in standard nuclear response vehicles and equipment.
