Definitions
- the X-ray protective metal sheet cannot be placed directly against the totality of the external faces of the device because of the often complex profile of this one.
- this profile complexity is often imposed by heat dissipation constraints.
- materials for protection against ⁇ and neutron radiation formed from a plastic or rubberized material containing powder of a salt of lead, tungsten, barium, cadmium, bismuth or tin of a saturated fatty acid. These materials are notably described in document FR-A-2 027 514 filed in the name of F. MARYEN.
- the amount of powder in the binder can be up to 50% by volume of the finished X-ray protection material. As with particle size, the higher the amount of powder, the more effective the protection. However, an amount of powder greater than 50% by volume is contrary to good mechanical strength of the material and good homogeneity of the latter. Furthermore, the minimum quantity of powder allowing effective protection against X-rays is 25% by volume of the finished protective material.
- These mixture granules are in particular introduced into a mold containing a box, intended to contain electronic circuits and to be protected against X-rays.
- the thickness of the protective coating depends on the efficiency of the desired X-ray filtering and the energy spectrum of these rays can be adapted in each case. However, a thickness of 1.5 mm may be sufficient in the majority of cases.
- a similar material can be obtained by replacing the DINYL resin with the HYTREL resin from DUPONT de NEMOURS, the latter being a polyether blocker (thermoplastic).
- the resin matrix of the protective material according to the invention is a thermoplastic resin
- the material will be mainly used as a coating material; it may cover a rigid housing or a flat or curved panel made of plastic or metal, an electrical conductor or an optical conductor of plastic or glass.
- the resin used must have a coefficient of expansion compatible with that of the material constituting the surface to be covered.
- a protective material according to the invention this can be produced directly in the form of a housing or a protective panel, rigid or flexible depending on the resin used.
- the invention applies when minimum mass conditions are required.
- the material according to the invention allows filtering efficiency equivalent to that of a sheet of solid material, a gain in mass, size and a reduction in manufacturing costs.
- the material according to the invention can be used advantageously to protect the electronic devices on board an aircraft.
