Abstract: The present invention relates to a method for continuous removal of carbon dioxide, the method comprising the steps of: a) preparing an aqueous solution containing an amine-based compound and an acidic calcium compound; b) bringing a gas containing carbon dioxide to be treated into contact with the aqueous solution to prepare a calcium carbonate precipitate; and c) recovering the calcium carbonate and then adding a basic calcium compound to the residual aqueous solution, wherein after step c), step b) and step c) are repeatedly performed. The removal of carbon dioxide by the method of the present invention has advantages of requiring low energy and being capable of mineralizing and removing carbon dioxide at a fast rate without a separate time for induction.

Abstract: The present invention relates to an airless tire, and includes first and second bands that face each other with a distance interposed therebetween, a plurality of spokes that connect the first band to the second band and are provided at intervals, and first and second connecting members that connect the adjacent spokes. The spoke includes a first member of which one end is curved from the first band toward the second band, and a second member of which one end is curved from the second band toward the first band. The other ends of the first and second members are connected to each other, and the first and second members are curved in opposite directions.

Abstract: Disclosed herein is a non-pneumatic tire with a reinforcing member. The non-pneumatic tire includes a tread part which comes into contact with the ground, a rim part which is coupled to an axle, an outer annular band part which forms an interface with an inner surface of the tread part, an inner annular band part which forms an interface with the rim part, a spoke part which is disposed between the outer annular band part and the inner annular band part and functions as a support, a connector which connects spokes of the spoke part to each other, and a reinforcing member which has a plate wire structure. The non-pneumatic tire can effectively and sufficiently withstand the weight of a vehicle. Further, the performance of the tire is balanced with respect to the contact area, the displacement extent and the resistance to rolling.

Abstract: A polyurethane foam which is obtained by a reaction between a diol component and a diisocyanate component, with the diol component being a mixture of a polyether-based diol and a polyester-based diol, and a pneumatic tire to which the polyurethane foam is applied are provided. When a soft polyurethane foam is produced using a mixture of a polyether-based diol and a polyester-based diol as the diol component, and by varying the content of the expanding agent during the production process, and when the polyurethane foam is disposed in the cavity of a pneumatic tire, the polyurethane foam thus produced has an effect of reducing the resonance noise generated in the cavity of the tire and improving durability of the tire.

Abstract: A non-pneumatic tire for a vehicle is disclosed. The non-pneumatic tire includes a tread, a rim part, inside and outside annular bands, a spoke member, and a pair of protective films. The tread comes into contact with a road surface. The rim part is connected to the axle of a vehicle. The inside and outside annular bands are disposed between the tread and the rim part, and are coaxially spaced apart from each other. The spoke member includes supports disposed in a predetermined pattern and configured to connect the inside and outside annular bands, and openings defined by the supports. The pair of protective films are disposed at both ends of the tire in the widthwise direction of the tire, and prevents foreign substances from infiltrating into the openings of the spoke member. The protective films are made of the same material as the spoke member and integrated with the spoke member.

Abstract: Disclosed herein is an airless are which absorbs shock and holds pressure applied to the tire through an auxetic spoke buffer without using air pressure. The airless tire includes a cylindrical tread being in contact with the ground, an axle fixing section having a smaller circumference than the tread and disposed inside the tread, and an auxetic spoke buffer connecting the tread and the axle fixing section and providing a buffering function. Accordingly, the airless tire is transformed only to an extent to properly function as a fire when the spoke buffer is transformed by pressure or impact and fully returns to an original shape when pressure or impact is removed.
