Problems solved by technology

Traditional standards mainly use the permeability or leakage of the material itself, and are affected by the difference of the material itself and the manufacturing process, so it is impossible to obtain a standard with uniform performance and cannot meet the needs of use.

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0021] It should be noted that when an element is referred to as being “disposed on” or “fixed on” another element, it may be directly on another element or there may be an intervening element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, it may be detachably fixed or non-detachably fixed therebetween. When an element is referred to as being "connected" or "rotatably connected" to another element, it can be directly connected to the other element or intervening elements may also be pres...

Abstract

The invention discloses a reference substance for detecting the permeation and leakage amount of steam and gas and a preparation method of the reference substance. The preparation method comprises thefollowing steps that a substrate whose barrier property or sealing performance satisfies a preset standard is selected; and the substrate is punched according to the preset standard to obtain the reference substance. According to the reference substance and the preparation method thereof, the reference substance with uniform performance can be obtained according to needs, and detection parametersof a detection instrument can be calibrated accurately.

Description

technical field [0001] The invention relates to the technical field of water vapor and gas detection, in particular to a standard substance for detecting the penetration and leakage of water vapor and gas and a preparation method thereof. Background technique [0002] Containers and the materials used to make them have an important function, that is, they need to have barrier or leak-proof performance against water vapor and gas, that is, the permeation rate of water vapor and gas to the container and the materials used to make them must meet the preset conditions. This property has a profound impact on the quality assurance of the contents stored in the container. According to national standards and industry standards, various testing instruments are used in conjunction with relevant testing methods to detect the permeation and leakage of containers and materials used in containers. When using a detection instrument for detection, it is necessary to use a standard to calib...
