    • Disclosed is a method for manufacturing an iron catalyst, the method including: a mixing stage where a mixture solution is manufactured by mixing iron nitrate (Fe(NO3)3) solution and copper nitrate (Cu(NO3)2) solution; a precipitation slurry-forming stage where a precipitation slurry is formed by adding at least one of sodium carbonate (Na2CO3) or sodium hydroxide (Na2CO3) solutions to the mixture solution; a washing stage where the precipitation slurry is filtered and washed with distilled water; a silica adding stage where fumed silica powder and potassium carbonate (K2CO3) solution are added to the precipitation slurry and then agitated; a drying stage where the precipitation slurry is passed through a sieve having a size of 30 μm to 100 μm and dried by a spry drying method to manufacture a powdered iron catalyst; and a heat treatment stage where the iron catalyst is dried at a temperature of 50° to 150° C., and then heat-treated at a temperature of 300° C. to 500° C.
    • 本发明公开了一种铁催化剂的制造方法,其特征在于,包括:将硝酸铁(Fe(NO 3)3)溶液与硝酸铜(Cu(NO 3)2)溶液混合,制成混合溶液的混合阶段; 沉淀浆液形成阶段,其中通过向混合物溶液中加入至少一种碳酸钠(Na 2 CO 3)或氢氧化钠(Na 2 CO 3)溶液形成沉淀浆料; 洗涤阶段,其中沉淀浆液被过滤并用蒸馏水洗涤; 二氧化硅添加阶段,将沉淀二氧化硅粉末和碳酸钾(K 2 CO 3)溶液加入沉淀浆料中,然后搅拌; 将沉淀浆料通过尺寸为30μm至100μm的筛子的干燥阶段,并通过干燥法干燥以制造粉末状铁催化剂; 以及铁催化剂在50℃〜150℃的温度下干燥,然后在300℃〜500℃的温度下进行热处理的热处理阶段。

    • 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.
    • 本文公开了一种无空气,其吸收冲击并且通过辅助轮辐缓冲器保持施加到轮胎上的压力,而不使用空气压力。 无气轮胎包括与地面接触的圆筒形胎面,具有比胎面更小的周边并且设置在胎面内部的车轴固定部,以及连接胎面和车轴固定部分并提供缓冲功能的辅助轮辐缓冲器。 因此,当通过压力或冲击而使轮辐缓冲器变形时,无气轮胎仅被变换到适当的火焰作用,并且当压力或冲击被去除时完全返回到原始形状。
