4 results about "Gas barrier" patented technology

The invention relates to the technical field of water electrolysis, and discloses a hydrogen-oxygen generator electrolysis device for alkaline electrolyte, which comprises a main tank body, a negativeelectrode and a positive electrode are arranged in the main tank body, a gas barrier film is arranged between the negative electrode and the positive electrode, and gas outlets positioned on two sides of the gas barrier film are formed in the top of the main tank body. An outer tank box is arranged outside the main tank body, liquid flow openings are formed in the outer walls of the two sides ofthe main tank body, and a liquid inlet pipe and a liquid outlet pipe are fixedly connected to the liquid flow openings respectively. The permanent magnets are arranged on the two sides of the main tank body, upward Lorentz force is applied to charged fluid between the negative electrode and the positive electrode through the magnetic fields of the permanent magnets, and therefore bubbles on the surfaces of the negative electrode and the positive electrode are promoted to fall off and move out of the space between the negative electrode and the positive electrode in an accelerated mode, and thearea where the negative electrode and the positive electrode are covered and inactivated is reduced; the high pressure drop caused by bubbles is reduced, and the purpose of reducing electrolysis energy consumption is achieved.

An improved nylon-free recyclable multilayer package and a method for manufacturing the same is provided that addresses the shortcomings of currently available recyclable materials for flexible packaging and containers. One object of embodiments of the present invention will be to provide a flexible plastic package suitable for curbside recycling, for example, a package that may be in compliance with recyclability as defined by the Association of Plastic Recyclers (APR). One such embodiment comprises a package manufactured from a material that is substantially free of nylon. Another or a second embodiment comprises a package manufactured from a material using a certain optimized ratio of compatibilizers in order to achieve suitable packaging performance and standards for recyclability. The flexible recyclable multilayer packaging material comprises a first laminate film and a second laminate film. The first laminate film further comprises, in order: a first sealable polyethylene layer with low initial seal band defining an exterior layer of the first laminate film; a second sealable polyethylene having a certain pre-determined thickness; a first tie layer; a first gas barrier layer of ethylene vinyl alcohol (EVOH); a second tie layer; a second sealable polyethylene layer; and a third sealable polyethylene layer. The second laminate film further comprises, in order: a first sealable polyethylene layer with low initial seal band defining an exterior layer of the second laminate film; a first sealable polyethylene layer having a certain pre-determined thickness; a first tie layer; a first gas barrier layer of ethylene vinyl alcohol (EVOH); a second tie layer; a second sealable polyethylene layer; a third sealable polyethylene layer; and wherein the flexible material is substantially free of nylon.

The present invention relates to a polyester fiber that can be applied to a fabric for an airbag, and particularly, to a polyester fiber having elongation of 0.5% or more at a stress of 1.0 g/d, elongation of 4.3% or more at a stress of 4.0 g/d, and elongation of 7.5% or more at a stress of 7.0 g/d, and an initial modulus of 40 to 100 g/d, a method of preparing the same, and a fabric for an airbag prepared therefrom. Since the polyester fiber of the present invention remarkably decreases stiffness and secures superior mechanical properties, it is possible to provide superior packing properties, dimensional stability, and gas barrier effect, and to protect occupants safely by minimizing the impact applied to the occupants, when it is used for the fabric for an airbag.
