  • Patent number: 11174599
    Abstract: A textile-reinforced concrete road paving apparatus and a method of repairing concrete road pavement can minimize use of construction equipment by using the textile-reinforced concrete road paving apparatus integrally formed to consecutively cut concrete, dispose a reinforcement material, and construct a repaired cross section so as to reduce a construction period, thereby remarkably reducing construction costs. Further, a textile grid reinforcement material, which is a noncorroding reinforcement material, is applied to form the repaired cross section of the concrete road pavement so as to prevent concrete from being detached due to corrosion. Further, a textile reinforced grid is precisely disposed at a required position, and thus the thicknesses of the primary and secondary concrete pavement are precisely adjusted, and thus construction precision can be increased.

  • Publication number: 20210130928
    Abstract: The present invention provides a method for selective recovery of a valuable metal from a waste denitrification catalyst through alkali fusion, the method comprising the steps of: (a) adding an alkali metal to a waste denitrification catalyst, followed by mixing and alkali fusion, to generate a calcination product; (b) subjecting the calcination product to water-leaching to recover an alkali leachate and a residue; (c) adding a precipitator to the alkali leachate, followed by stirring, to recover calcium metavanadate (Ca(VO3)2) or calcium tungstate (CaWO4) through precipitation; and (d) subjecting the recovered calcium tungstate to acid decomposition to prepare tungstic acid. Therefore, vanadium and tungsten can be recovered at high efficiency by a method in which a precipitator is added to a leachate, which is obtained by adding an excess amount of an alkali metal to a waste denitrification catalyst and carrying out calcination and water-leaching, and then a reaction rate is controlled.

  • Publication number: 20210114414
    Abstract: The present invention relates to a tire cord and a radial pneumatic tire, and is characterized in that when one raw nylon 6,6 or nylon 6 yarn and one aramid yarn are pre-twisted respectively and are then cabled to generate a raw cord, and when the raw cord is untwisted, the aramid yarn is input 5 to 100 mm/m longer than the nylon 6,6 or nylon 6 yarn. The hybrid dip cord according to the present invention has an excellent fatigue resistance of 80% or more, the initial deformation in the tensile test causes low modulus to be generated by nylon and causes high modulus to be expressed from the section where aramid begins to receive the force. As such, deformation is easy during the work of inflating the green tire inside the mold with the bladder, which makes the manufacturing of tires easy.
