TL;DR: A gas barrier polymer composition with active hydrogen functionality is provided in this article, where the polymer may be prepared by reacting a solution of organic diacid containing at least one active hydrogen group and diglycidyl ether in the presence of an optional catalyst.
Abstract: A gas barrier polymer composition with active hydrogen functionality is provided. The polymer may be prepared by reacting a solution of organic diacid containing at least one active hydrogen group and diglycidyl ether in the presence of an optional catalyst. The pressure, temperature, and time parameters of the reaction are preferably regulated to prevent degradation and subsequent incorporation of degradation products of organic diacid containing at least one active hydrogen group into the gas barrier polymer composition. A formulation of the gas barrier polymer composition and a carrier may be used to coat plastic materials, containers, and preforms. The gas barrier polymer composition may also be employed in a method of making multilayer packaging materials or container preforms. The multilayer packaging materials or preforms can be used to make containers useful in packaging gas sensitive substances.

TL;DR: In this article, a method for compositely air-conditioning and preserving large cherries is proposed, which comprises the following steps of: (1) selecting fresh and non-rotten large fruits, drying the large fruits in the air at room temperature for 1.5-2 h, immersing the large fruit in ozone water for 1-2 min, and drying the fruit after taking out; and (2) putting the fruit in a polypropylene tray, sealing and packaging the tray through a micro-porous film, and storing the fruit at 0
Abstract: The invention discloses a method for compositely air-conditioning and preserving large cherries. The method comprises the following steps of: (1) selecting fresh and non-rotten large cherries, drying the large cherries in the air at room temperature for 1.5-2 h, immersing the large cherries in ozone water for 1-2 min, and drying the large cherries in the air after taking out; and (2) putting the large cherries in a polypropylene tray, sealing and packaging the polypropylene tray through a micro-porous film, and storing the large cherries at 0-4 DEG C. According to air-conditioning packaging integrated optimal process parameters and an air-conditioning packaging design method, the characteristic parameters of required packaging films are determined, and packaging films with adaptive gas permeability are screened; or the required packaging gas permeability requirements are realized through the micro-porous (punched) film; a high-efficiency and safe ozone sterilization technology is adopted; and the disadvantages, such as low gas mixing precision and replacement precision, low packaging speed, high investment, high energy consumption and the like, in the traditional air-conditioning packaging can be overcome.

TL;DR: In this article, a system consisting of a circuit module, an optical module, and a gas channel module is presented for analyzing complicated component gas in multiple gas chambers, and belongs to the field of gas analysis.
Abstract: The invention discloses a system and a method for analyzing complicated component gas in multiple gas chambers, and belongs to the field of gas analysis. The system comprises a circuit module, an optical module and a gas channel module, wherein the gas channel module comprises a sample gas chamber for packaging gas to be detected which is formed by mixing a plurality of components and a plurality of standard gas chambers for respectively packaging single component gas in each gas chamber according to the composition components of the gas to be detected. Because beam-splitting lasers entering all the gas chambers are originated from the same light source, the drifting of the wavelength has a consistency property, and the influences on a signal to be detected and a reference signal are synchronous; in addition, the structures of the multiple gas chambers are positioned at the same environment temperature, and relative changing degrees of spectral curves of the gas to be detected and reference gas are consistent. To sum up, even if the wavelength of the laser is drifted or an environment temperature is changed, the influences of unstable factors are still evaluated by the reference signal in real time, so that precise inversion on the concentration of the gas to be detected is realized.
