Abstract
The utility model discloses a wide-width nuclear track membrane. The wide-width nuclear track membrane comprises at least two pieces of nuclear track membrane bodies; edges of the nuclear track membrane bodies are stuck by a glue layer to form the wide-width nuclear track membrane. With the adoption of the wide-width nuclear track membrane, the plurality of pieces of independent nuclear track membranes are compounded together by the glue layer to obtain the width-controllable wide-width nuclear track membrance, so that the wide-width nuclear track membrane is convenient to apply.
Description
Technical field
The utility model relates to microporous barrier field, particularly a kind of wide cut nucleopore membranes.
Background technology
Nucleopore membranes has another name called nuclear track-etching-film, it is a kind of novel microporous filter membrane, it adopts high-energy heavy ion irradiation plastic film material, on the path of ion process, forms radiation injury, chemical etching processing postmenstruation, damage field is enlarged to micron dimension, form micro channel, irradiation beams intensity of flow and exposure time determine pore density, i.e. micropore quantity in every square centimeter, chemical etching conditional decision micro-pore diameter and shape, in nucleopore membranes, pore density can be accurately controlled.
Compare compared with other class film material, the advantage that nucleopore membranes is the most outstanding is aperture homogeneous, and all micropores are in the same size, and hole shape rule is clear opening, and micropore size, density and film material thickness can be selected as required, make, and can accurately control.
Existing nucleopore membranes is only 250mm～500mm because its preparation technology's restriction causes restricted width, the width of common nucleopore membranes, in actual applications very inconvenience.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of width controlled, applies wide cut nucleopore membranes easily.
For solving the problems of the technologies described above, the wide cut nucleopore membranes that the utility model provides comprises at least two nucleopore membranes, and the limit of described nucleopore membranes is by the described wide cut nucleopore membranes of the bonding one-tenth of glue-line.
Preferably, the thickness of described nucleopore membranes is 5 μ m～50 μ m.
Preferably, the aperture of the micropore in described nucleopore membranes is 0.1 μ m～10 μ m, and the density of the micropore in described nucleopore membranes is 1 × 10
5/ cm
2～3.0 × 10
8/ cm
2.
Preferably, described wide cut nucleopore membranes comprises three nucleopore membranes, and wherein the both sides of a slice nucleopore membranes are mutually bonding with one side of other two nucleopore membranes by glue-line.
Preferably, the material of described glue-line is PUR or adhesive sticker or thermal adhesive resin.
Preferably, the thickness of described glue-line is 1 μ m～10 μ m.
Preferably, the width of described glue-line is 2mm～20mm.
Preferably, each described nucleopore membranes is wide.
Preferably, the arranged in step shape that described nucleopore membranes tapers off after bonding.
Wide cut nucleopore membranes of the present utility model by multi-disc independently nucleopore membranes be combined with each other by glue-line, obtained the controlled wide cut nucleopore membranes of width, make the application of nucleopore membranes more convenient.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the utility model wide cut nucleopore membranes;
Fig. 2 is the top view of Fig. 1.
In figure, indicate as follows:
Wide cut nucleopore membranes-1, nucleopore membranes-11, glue-line-12.
Detailed description of the invention
For the above-mentioned purpose, the feature and advantage that make utility model can become apparent more, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
A lot of details are set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that, and therefore the utility model is not subject to the restriction of following public specific embodiment.
The utility model provides a kind of wide cut nucleopore membranes 1, and it comprises at least two nucleopore membranes 11, and the limit of described nucleopore membranes 11 is by the described wide cut nucleopore membranes 1 of the bonding one-tenth of glue-line 12.The nucleopore membranes of suitability for industrialized production is all the goods of rolling, and its length is not limit, and width is limited, according to needed width, selects the nucleopore membranes of suitable number, and multi-disc nucleopore membranes is bonding by glue-line, obtains the controlled wide cut nucleopore membranes of width.
In order to make wide cut nucleopore membranes more durable, the thickness of described nucleopore membranes 11 is preferably 5 μ m～50 μ m, more preferably 10 μ m～30 μ m, and the thickness of each monolithic nucleopore membranes 11 is 10 μ m～30 μ m.
For filtered air better, the aperture of the micropore in described nucleopore membranes 11 is preferably 0.1 μ m～10 μ m, and the density of the micropore in described nucleopore membranes 11 is 1 × 10
5/ cm
2～3.0 × 10
8/ cm
2.
In a preferred embodiment of the present utility model, described wide cut nucleopore membranes 1 comprises that three nucleopore membranes 11(as shown in Figure 1), wherein the both sides of a slice nucleopore membranes 11 are mutually bonding with one side of other two nucleopore membranes 11 by glue-line 12, more preferably, the limit of above-mentioned nucleopore membranes 11 is the limit (in Fig. 2, four-headed arrow is depicted as the width of nucleopore membranes) on width.
In a preferred embodiment of the present utility model, the material of described glue-line 12 is PUR or adhesive sticker or thermal adhesive resin, and wherein thermal adhesive resin is preferably PE or PETG etc.
In a preferred embodiment of the present utility model, the thickness h of described glue-line 12 is 1 μ m～10 μ m.
Because the micropore of nucleopore membranes bonding location is covered by glue-line, cannot realize filtering function, for by each nucleopore membranes strong bond together time, the filter area of the nucleopore membranes that as far as possible avoids waste, the width d of described glue-line 12 is preferably 2mm～20mm.In addition,, in order to facilitate suitability for industrialized production, each described nucleopore membranes preferably can be wide.
In order to make the filter effect of nucleopore membranes more excellent, the arranged in step shape tapering off after described nucleopore membranes 11 is bonding.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and be only subject to the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essence design of the present utility model and scope.
