Problems solved by technology

Due to the thin thickness of the permeable membrane, it is necessary to use tweezers or other tools to clamp it from the plane, which may easily cause the permeable membrane to be damaged or even torn during the clamping process, and the permeable membrane is easy to Wrinkles or even folds occur, which not only causes inconvenience to the test but also greatly reduces the accuracy of the membrane permeability test

Embodiment 1

[0045] Embodiment 1: The first film-forming surface is located at the outer edge of the second film-forming surface

[0046] When the tray 1 is combined with the film forming plate 2 , the first film forming surface 101 is located at the outer edge of the second film forming surface 201 . The tray 1 has a groove 102 for accommodating the film forming plate 2 , and the first film forming surface 101 is located on the upper surface of the tray 1 .

[0047] In some embodiments, the device includes a baffle 3 for forming a chamber together with the first film-forming surface and the second film-forming surface. When the first film-forming surface 101 is located at the outer edge of the second film-forming surface 201, The baffle 3 is located on the first film forming surface 101 . For example figure 1 As shown, the baffle 3 is fixed on the upper surface of the tray 1 . The baffle 3 is in the shape of a ring. When the film-forming plate 2 is accommodated in the tray groove 102, ...

Embodiment 2

[0061] Embodiment 2: The second film-forming surface is located at the outer edge of the first film-forming surface

[0062] The tray 1 has a protrusion 104, the first film-forming surface 101 is located on the upper surface of the protrusion 104, and the film-forming plate 2 has a through hole 203 for being sleeved on the protrusion. One end of the protrusion is connected with the tray, the other end of the protrusion is a free end, and the end surface of the free end of the protrusion is the upper surface of the protrusion.

[0063] In some embodiments, the protrusion 104 is cylindrical, such as Figure 5 shown.

[0064] In some embodiments, the device includes a baffle for forming a cavity together with the first film-forming surface and the second film-forming surface. When the second film-forming surface 201 is located at the outer edge of the first film-forming surface 101, the baffle The plate is located on the second film-forming surface. E.g Image 6 with Figure...

Abstract

The invention provides a permeable membrane preparation device, which facilitates the preparation and transfer of the membrane, and keeps the membrane flat during the transfer process, thereby improving the accuracy of the membrane permeability test. The permeable membrane preparation device includes a tray and a film-forming plate. The tray has a first film-forming surface, and the film-forming plate has a second film-forming surface. When the tray and the film-forming plate are combined, the first film-forming surface and the second film-forming surface The surfaces jointly form the surface for forming the permeable membrane; when the tray is separated from the film-forming plate, the film-forming plate can drive the permeable membrane to separate from the tray. When the tray is combined with the film forming plate, the first film forming surface and the second film forming surface are located in the same horizontal plane.

Description

technical field [0001] The invention relates to the field of membrane permeability testing, in particular to a permeable membrane preparation device. Background technique [0002] The following background art is provided to help the reader understand the present invention and is not to be admitted as prior art. [0003] Membrane permeability testing is used to detect the speed and extent of small molecule substances passing through the membrane. Conducting a membrane permeability test begins with the preparation of the permeable membrane and then mounting the permeable membrane on a diffusion cell. Usually, the polymer to be tested is dissolved in an organic solvent to form an organic solution, and then the organic solution is poured on a flat surface. After the organic solvent is volatilized, a permeable membrane is formed, and then the permeable membrane is cut into the desired shape and transferred. Mounted on diffusion cell. Due to the thin thickness of the permeable ...
