Abstract: The present invention provides a spray-applied polyurethane insulation material for tunnels in cold regions, its application, and its construction method. The spray-applied polyurethane insulation material for tunnels in cold regions is composed of raw materials with a mass ratio of 0.8-1.2 of material A and material B. By mass parts, material A includes 90-100 parts of polyether polyol, 90-100 parts of polyester polyol, 5-10 parts of chain extender, 1-4 parts of catalyst, 10-20 parts of flame retardant, 0.5-3 parts of water, and 1-3 parts of surfactant. The B component is diphenylmethane diisocyanate. The flame retardant is composed of flame retardant A and flame retardant B in a mass ratio of 10:1-2.5. The spray-applied polyurethane insulation material of the present invention is used to construct tunnel structures in cold regions, providing good flame retardant and insulation effects.

Abstract: A novel sweat absorbing textile electrode comprises a textile electrode body and an electrical coupling member, the textile electrode body comprising a conductive foam and a conductive fabric wrapped around the conductive foam, the electrical coupling member being fixed on the conductive fabric; wherein a through hole is provided on the conductive fabric on the side in contact with the human skin. The textile electrode has a light weight, small size and soft texture. It fits on the skin, has good air permeability, and is capable to absorb sweat, which can prevent short circuit between electrodes caused by sweat and be used for collecting bioelectrical signal when sweat comes out from human body. It may also be applied in bioelectrical signal monitoring in high temperature, high humidity environment, and during daily exercise.
