Description
Technical field
The utility model relates to Application of Nuclear Technology technical field, especially relates to a kind of device of manufacturing the heavy ion irradiation film of multi-angle nuclear track.
Background technology
Heavy ion microporous filter membrane (also claiming " nucleopore membranes " or " nuclear pore membrane ") has the features such as aperture homogeneous, precision is high, biological stability is good, is a kind of filtering material of function admirable.But because its porosity is lower, make its flow velocity be subject to very large restriction.In order to improve flow velocity, the porosity of filter membrane need to be improved as far as possible, but filter film strength can be reduced simultaneously, bring inconvenience to production and the use of filter membrane, even cannot produce and use.
The standard manufacture craft of heavy ion microporous filter membrane is: 1, irradiation, utilizes the heavy ion of heavy ion avcceleration generation or the fission fragment bombardment organic film (calling " basement membrane " in the following text) of nuclear reactor generation; 2, ultraviolet sensitization (optional), irradiates the good film of irradiation with the ultraviolet ray of certain wavelength and power; 3, chemical etching, carries out etching with specific alkali (or acid) solution to irradiated membrane; 4, clean, heavy ion microporous filter membrane etching being completed by deionized water cleans; 5, dry, with hot blast, the filter membrane having cleaned is dried.
In order to improve the porosity (or title " percent opening ") of heavy ion microporous filter membrane, conventionally by improving pore density and the micropore size of filter membrane, realize, after (particulate of filtering certain size) micropore size is determined in application-specific, can only increase by increasing irradiation density (increasing hole density) porosity of filter membrane.The particle or the fission fragment that due to accelerator or reactor, produce are random generations, inevitably there will be the overlapping phenomenon of nuclear track, also just cause filter membrane to occur repeated hole phenomenon.Density is higher, and repeated hole probability is larger, and filter membrane intensity is lower, and repeated hole can cause the rejection rate of filter membrane to decline in a large number, cannot satisfy the demands.
Existing irradiance method is that the point-like particle beams is defocused to basement membrane with wide threadlike particle bundle with multistage lens, then by the running of film guiding mechanism, drives the rotation of basement membrane, thereby reaches the object of the whole film material of whole irradiation.The heavy ion irradiation film that this method makes transversely (perpendicular to film direct of travel) each nuclear track presents low-angle angle, angle <5 °, and in the vertical each nuclear track substantially in parastate.The heavy ion membrane of this kind of method irradiation can produce a large amount of repeated holes through following process.
