Embodiment Construction

[0012] A liquid nitrogen protective glove, comprising a wear-resistant layer, a waterproof layer, and a thermal insulation layer sequentially arranged from the outside to the inside, the waterproof layer adopts a material layer with a breathable function, and the thermal insulation layer adopts thermal insulation polyurethane textile fibers. The setting of the waterproof layer ensures that after the gloves are in contact with liquid nitrogen, the moisture in the air condenses on the surface of the gloves and wets the gloves due to the low temperature.

[0013] In the above technical solution, the wear-resistant layer is made of Cordura fabric. High wear resistance, light, quick-drying, soft, durable, etc., so it can effectively prolong its service life, as the surface layer in direct contact with the human body, it has high comfort, and when water drops on it, it can Dries quickly to avoid waterlogged comfort.

[0014] The wrist of the glove body is provided with Velcro for t...

Abstract

The invention discloses liquid nitrogen protection gloves. The liquid nitrogen protection gloves aim at solving the problem of poor gas permeability of traditional liquid nitrogen protection gloves; each glove comprises an abrasion-resistant layer, a waterproof layer and a heat-insulating layer which are sequentially arranged from outside to inside, the waterproof layer adopts a material layer with a gas permeation function, and the heat-insulating layer adopts heat-insulating polyurethane textile fibers. Through the arrangement of the waterproof layers, it is ensured that after the gloves arein contact with liquid nitrogen, since the temperature is low, moisture in air is condensed on the surfaces of the gloves to wet the gloves.

Description

Background technique [0001] Liquid nitrogen protective gloves are effective in protecting hands and arms from ultra-low temperature liquids, and can be used for work related to ultra-low temperature environments such as liquid nitrogen, liquid oxygen, liquid argon container operations or ultra-low temperature refrigerators, cold storage and dry ice, etc. [0002] Wearing liquid nitrogen protective gloves can directly obtain nitrogen from liquid nitrogen containers such as liquid nitrogen Dewar bottles and liquid nitrogen tanks; it is widely used around the world and is suitable for low temperature gas, low temperature refrigeration, dry ice, cold room, etc.; it is used in biomedicine, Laboratory research, industry, aerospace, frozen food processing and any other places where extreme cold is protected. Liquid nitrogen resistant gloves cannot be immersed in cryogenic liquids, even though industrial quality liquid nitrogen resistant gloves have limited abrasion resistance. [00...
