Description
Technical field
It the utility model is related to a kind of composite membrane, more particularly to a kind of antiacid alkali diaphragm.
Background technology
At present, conventional acrylic diaphragm does not have the performance of antiacid alkali, is easily used to occur in soda acid processing procedure residual
Situations such as glue, infiltration, and once there is breakage in film, will cause larger economic loss.
Improve the function of antiacid alkali, it usually needs again using new safeguard measure, such as increase more one layer of packaging means,
This means will generally put into more materials and manpower, not meet energy-conserving and environment-protective economic principle.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of antiacid alkali diaphragm.
One of the purpose of this utility model adopts the following technical scheme that realization：
A kind of antiacid alkali diaphragm, includes release layer, PET basic units and hydrophobic layer successively from top to bottom, on release layer top surface
Thickness reducing part is provided with to queue, the bottom surface of release layer and PET basic units are bonding, and hydrophobic layer is mesh, and the thickness of hydrophobic layer is 10-
20 μm, the mesh aperture of hydrophobic layer is 2-10 μm.
Further, thickness reducing part is shaped as bar shaped or waveform.
Further, antiacid alkali diaphragm is in web-like, and the bearing of trend of thickness reducing part and winding direction are perpendicular.
Further, the mesh aperture of hydrophobic layer is 4-8 μm.
Further, the mesh form of hydrophobic layer is regular hexagon or regular pentagon.
Further, the mesh form of hydrophobic layer is circular or ellipse.
Compared with prior art, the beneficial effects of the utility model are：
1. antiacid alkali diaphragm provided by the utility model by setting a release layer, can effectively improve PET basic units to by
The adsorption capacity of object is protected, and thickness reducing part is set on release layer, PET basic units can be effectively improved and be attached at protected object
Compactness during face to be protected；
2. the antiacid alkali diaphragm can efficiently reduce soda acid liquid pair by setting the hydrophobic layer with micron order mesh
The surface tension of PET basic units so that the amount of the soda acid liquid of contact PET basic units greatly reduces, and then effectively improve to by
Protect the antiacid alkali protective capability of object.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure, each reference：1st, release layer；11st, thickness reducing part；2nd, basic unit；3rd, hydrophobic layer.
Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further, it is necessary to explanation is,
On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
In detailed description below, described " on ", " under ", " top ", " bottom " etc. have showing for temporald eixis meaning
Meaning word, it is understood that to the temporald eixis of accompanying drawing, and should not be construed the direction signal of product in practice.
As shown in figure 1, a kind of antiacid alkali diaphragm, includes release layer 1, PET basic units 2 and hydrophobic layer 3 successively from top to bottom,
Thickness reducing part 11 is provided with to queue on release layer top surface, the bottom surface of release layer and PET basic units are bonding, and hydrophobic layer is mesh, dredge
The thickness of water layer is 10-20 μm, and the mesh aperture of hydrophobic layer is 2-10 μm.
The antiacid alkali diaphragm, on the one hand it is bonded journey by setting release layer with improve PET basic units and plane to be protected
Degree, on the other hand by setting the hydrophobic layer with micron order mesh to reduce the amount of the soda acid contacted with PET basic units, so as to have
Improve protective capability of the diaphragm to plane to be protected in effect ground.
The bonding mode of the antiacid alkali diaphragm, release layer and PET basic units includes but is not limited to electrostatic bonding, adhesive glues
Close.The adhesive surface of release layer and PET basic units should be it is smooth such as minute surface, with improve release layer and PET basic units it is release after, PET
Basic unit has a preferable electrostatic adsorption force and fitting negative pressure to plane to be protected.Release layer is with PET basic units using gluing
When mode bonds, when tearing release layer, the surface of PET basic units is in static behaviour, can improve PET basic units to plane to be protected
Adsorption capacity.
Hydrophobic layer can be relative to PET basic units independence or after PET substrate surfaces carry out apertured processing
Formed.When hydrophobic layer is independent, hydrophobic layer with PET basic units is compound in one in the form of bonding.
In the utility model, the shape of the thickness reducing part includes but is not limited to bar shaped or waveform.Release layer is preferably toughness
Higher than the material of PET basic units, on the one hand play a supporting role, it is on the other hand convenient PET basic units is attached at protected plane
When, improve compactness of the PET basic units to plane.
In the utility model, the storage form of antiacid alkali diaphragm includes but is not limited to web-like, i.e., antiacid alkali diaphragm is in
Web-like.On this basis, the bearing of trend of thickness reducing part and winding direction are perpendicular.That is the bearing of trend of thickness reducing part and the volume of winding
Direction of principal axis is parallel.I.e. thickness reducing part is advantageous to, in winding, preferably be bonded with spool body.
In the utility model, the mesh aperture of hydrophobic layer is 4-8 μm.Its surface tension of the mesh in the aperture has greatly preferable
Hydrophobic ability.The mesh form of hydrophobic layer is regular hexagon or regular pentagon.That is mesh is can in the horizontal direction regularly
Extend.On the other hand, the mesh form of hydrophobic layer can also be circular or ellipse, and soda acid liquid is dredged with improving hydrophobic layer
Outlet capacity.
Above-mentioned embodiment is only preferred embodiment of the present utility model, it is impossible to is protected with this to limit the utility model
Scope, the change of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model scope claimed.
