Abstract
An oxygen permeable membrane comprises a polymer membrane layer, a support layer, and a nonwoven cloth layer; wherein the polymer membrane layer, the support layer, and the nonwoven cloth layer are laminated in sequence; and the polymer membrane layer is made of a polymer material. Because oxygen and nitrogen in the air go through the polymer membrane layer at different speeds, oxygen and nitrogen are separated. The oxygen permeable membrane has the advantages of quick oxygen production speed, small volume, and low cost. At the same time, the oxygen permeable membrane can be applied to oxygen permeable membrane oxygen generator and oxygen enriched air conditioner to increase the oxygen concentration.

Begin to same or similar label eventually represent same or similar element or there is the unit of same or like function
Part.The embodiment described below with reference to accompanying drawing is exemplary, is only used for explaining the present invention, and can not
It is interpreted as limitation of the present invention.
In describing the invention, term " interior ", " outward ", " longitudinally ", " laterally ", " on ", D score, " top ",
Orientation or the position relationship of the instruction such as " end " they are based on orientation shown in the drawings or position relationship, merely to just
In describing the present invention rather than requiring that the present invention must not be understood that with specific azimuth configuration and operation
For limitation of the present invention.
Referring to shown in Fig. 1, the oxygen permeable membrane 1 of an embodiment includes: include the polymeric membrane stacked gradually
Layer 10, supporting layer 11 and nonwoven layer 12.Wherein:
Described macromolecule membranous layer 10 is made up of macromolecular material, can pass through the gas of molecular level.
Described supporting layer 11 is loose structure, and its material and performance play decisive role.In this enforcement
In example, described supporting layer 11 uses the solvent-proof new modified polyacrylonitrile of high-strength high temperature-resistant as support
Layer, has molecular weight height, the characteristic of narrow molecular weight distribution, and performance is better than domestic polysulfones macromolecular material.
Described nonwoven layer 12 is made up of that orient or random fiber, is used for supporting and ventilative.
Preferably, in the present embodiment, described polymeric membrane layer thickness is 1 μm, described supporting layer
Thickness is 40 μm.
Below incorporated by reference to Fig. 2, under the pressure of oxygen permeable membrane 1 both sides, utilize gas with various molecule in air saturating
Crossing the speed difference of macromolecule membranous layer 10 and realize separating at 1 liang of lateral enrichment of oxygen permeable membrane, infiltration rate is fast
Gas is enriched with in per-meate side, and the slow gas of infiltration rate is then enriched with in feed side.
Specific as follows:
Although oxygen and the kinetics radius of nitrogen in air are more or less the same.But when air passes through macromolecule
During film layer 10, utilize oxygen and nitrogen to have different solubility factor, diffusion coefficient and infiltration coefficients, come
Realize nitrogen, oxygen separating, thus at the per-meate side certain density oxygen of generation of described oxygen permeable membrane 1.
Owing to oxygen and nitrogen have different solubility factor S and diffusion coefficient in macromolecule membranous layer 10
D, the infiltration coefficient P of the two is the most different, and the infiltration coefficient of usual oxygen is more than the infiltration coefficient of nitrogen.Infiltration system
Number P is defined as solubility factor S and diffusion coefficient D is long-pending, reflects the capacity of water of air penetrating film,
It is expressed as: P=DS.Employing Barrer is as the unit of air transmission coefficient the most mostly,
