Abstract
The invention discloses an isolation film hole diameter measuring method. According to the method, firstly, a first surface hole diameter is determined, the shape of the surface hole is circular; secondly, the shape of a second surface hole is determined, a structure of the second surface hole is determined by fiber polymerization; lastly, the hole diameter is calculated according to a waterpower diameter and hole diameter relation. Through the method, each hole diameter can be measured, and measurement is more convenient and rapid.
Description
Technical field
The invention belongs to barrier film inside diameter measurement technical field, relate in particular to a kind of barrier film pore size measuring method.
Background technology
Barrier film comprises the open pore of inleakage conventionally, but for good electric conductivity and cycle performance is provided, on the different surface of barrier film, the structure in hole is also different.In order to characterize pore texture, need to obtain the hole diameter of every one deck, still, due to the scrambling of air hole structure, must measure the diameter in each hole at present.
Summary of the invention
In order to address this problem, invent a kind of pore size measuring method, utilize hydraulic diameter method to measure the diameter in hole.
The embodiment of the present invention is achieved in that a kind of barrier film pore size measuring method, it is characterized in that, the method comprises:
Determine first surface aperture, be shaped as circle in this surface holes;
Determine second surface hole shape, this surperficial pore structure is determined by fiber polymerization;
By hydraulic diameter and aperture relational expression calculated hole diameters size.
Further, described barrier film contains two surfaces, and the pore shape of first surface is circular, and the diameter in hole is equivalent to hydraulic diameter hole D
h, expression formula is as follows:
Wherein, D
hfor hydraulic diameter; D is the diameter in hole.
Further, the polymerization that the gap structure of described second surface is connected by fiber forms, and due to aperture scrambling, calculate by following formula hydraulic diameter in this surperficial aperture:
Wherein, A is the area of section that fluid flows through; P is the moistening circumferential length of fluid.
Pore size measuring method provided by the invention, first determine first surface aperture, be shaped as circle in this surface holes, then determine second surface hole shape, this surperficial pore structure is determined by fiber polymerization, finally by hydraulic diameter and aperture relational expression calculated hole diameters size.The method can realize the measurement to each bore dia, convenient, quick.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of the method measured of the pore size that provides of the embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The method that the pore size that Fig. 1 shows the invention process case to be provided is measured, the method comprises:
In S101, determine first surface aperture, be shaped as circle in this surface holes;
In S102, determine second surface hole shape, this surperficial pore structure is by the poly-platform of fiber
institute determines;
In S103, by hydraulic diameter and aperture relational expression calculated hole diameters size.
Barrier film contains two surfaces, and the pore shape of first surface is circular, and therefore, in this case, the diameter in hole is equivalent to hydraulic diameter hole D
h, expression formula is as follows:
Wherein, D
hfor hydraulic diameter; D is the diameter in hole.
The polymeric plate that the gap structure of second surface is connected by fiber forms, due to aperture scrambling, so calculate by following formula hydraulic diameter in this surperficial aperture:
Wherein, A is the area of section that fluid flows through; P is the moistening circumferential length of fluid.
Finally, by hydraulic diameter and aperture relational expression calculated hole diameters size.
The pore size measuring method that the embodiment of the present invention provides, first determine first surface aperture, be shaped as circle in this surface holes, then determine second surface hole shape, this surperficial pore structure is determined by fiber polymerization, finally by hydraulic diameter and aperture relational expression calculated hole diameters size.The method can realize the measurement to each bore dia, convenient, quick.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
