Embodiment 1

[0033] refer to figure 2 , a protective structure for nuclear microporous membrane production process of the present invention includes a thickness of 15 microns for forming the first membrane layer 1 of the first nuclear microporous membrane, which is considered unnecessary on one side of the first membrane layer The position of the micropore is coated with the first protective layer 2, and the other side of the first film layer is compounded with a thickness of 12 microns. The protective film layer 3 is compounded with A thickness of 15 microns is used to form the second membrane layer 4 of the second nuclear microporous membrane, and the second membrane layer 4 is coated with the second membrane layer 4 on the opposite side of the composite surface of the protective membrane layer, where micropores are not needed. Second protective layer 5.

Embodiment 2

[0035] refer to image 3 The difference between this embodiment and the first embodiment is that the first film layer 1 and the second film layer 4 are combined with the protective film layer through an adhesive after the release layer 6 is coated.

Embodiment 3

[0037] One of the nuclear microporous membrane production methods using the protective structure of embodiment two, characterized in that the steps are as follows:

[0038] (1) coating protective layer (imaging): the first film layer 1 and the second film layer 4 are considered to be coated with protective layer 2 (5) at positions where micropores are not needed on one side, and dried.

[0039] (2) Coating release layer 6 and adhesive: coating release layer 6 and adhesive sequentially on the sides of the first film layer 1 and the second film layer 4 that are not coated with protective layers.

[0040] (3) Two-time compounding: the two sides of the protective film layer are respectively bonded to the release layer 6 on the first film layer 1 and the second film layer 4 through an adhesive.

[0041] (4) Irradiation (bombardment): adjust the intensity of the irradiation energy to reach the intensity that can penetrate the first and second film layers respectively, and irradiate ...

Abstract

The invention relates to a safeguard structure used in a nuclepore membrane production process. The safeguard structure used in the nuclepore membrane production process in the invention comprises a first membrane layer for forming a first nuclepore membrane, a first protective layer is coated on positions on the first membrane, where micropore are considered to be unnecessary, and a protective membrane layer is compounded on the other surface of the first membrane layer. The safeguard structure is characterized in that a second membrane layer for forming a second nuclepore membrane is compounded on the other surface of the protective membrane layer, which is opposite to the compound surface of the first membrane layer, and a second protective layer is coated on positions of the other surface of the second membrane layer, which is opposite to the compound surface of the protective membrane layer and is considered to be in no need of micropores. The safeguard structure and the production method, disclosed by the invention, have the advantage of increasing the production efficiency of the nuclepore membranes.

Description

technical field [0001] The invention relates to a protective structure used in the production process of nuclear microporous membranes. Background technique [0002] Nuclear microporous membranes are popular in the market for anti-counterfeiting and filtering purposes, especially for anti-counterfeiting. They cannot be imitated and are easily recognized by consumers. They are also the choice of high-end customers, so the market demand is growing rapidly. The production process of the nuclear microporous membrane is to bombard (irradiate) the polymer material membrane with the fission particles produced by the nuclear reactor or the high-energy particles produced by the tandem heavy ion accelerator, and damage its molecular chain, and the part of the damaged molecular chain will form Different from the acid-base properties of raw materials, the damaged polymer chains after irradiation bombardment will be dissolved (etched) when placed in lye (or acid) to form Tens of million...
