    • The present invention relates to a process for preparing a liquid silicate carbonate antiseptic agent. According to the present invention, the liquid silicate carbonate antiseptic agent is prepared by the process which comprises a step of dissolving 80-120 g of a silicate in 1 l of purified hot water at 70-90° C. until the silicate is completely ionized; a step of homogeneously emulsifying the mixture by adding 8-15 g of a emulsifier; and a step of stabilizing the resulting mixture by adding sodium carbonate (Na2CO3) and potassium carbonate (K2CO3) as carbonates in an amount of 45-80 g, respectively, and stirring the mixture. The liquid silicate carbonate antiseptic agent according to the present invention is characterized by the fact that in preparing the carbonate in a saturation state with sodium carbonate and potassium carbonate, the saturated carbonate is stabilized in aqueous solution by the addition of an effective amount of silicate and emulsifier and the heat treatment, and it has a broad disinfecting and biocidal effects on viruses, gram-positive bacteria and gram-negative bacteria even at a relatively low carbonate concentration and can maintain a sustained biocidal activity.
    • 本发明涉及一种制备液体硅酸酯碳酸盐防腐剂的方法。 根据本发明,通过包括以下步骤制备液体硅酸酯碳酸盐防腐剂,该方法包括将70-120g硅酸盐在70-90℃下溶解在1升纯化的热水中,直到硅酸盐完全离子化 ; 通过加入8-15g乳化剂均匀乳化混合物的步骤; 和通过分别以45-80g的量加入碳酸钠(Na 2 CO 3)和碳酸钾(K 2 CO 3)作为碳酸酯并搅拌该混合物来稳定所得混合物的步骤。 根据本发明的液体硅酸酯碳酸盐防腐剂的特征在于,在用碳酸钠和碳酸钾制备饱和状态的碳酸盐时,通过加入有效量的硅酸盐使饱和碳酸酯稳定在水溶液中, 乳化剂和热处理,并且即使在相对低的碳酸盐浓度下也具有对病毒,革兰氏阳性菌和革兰氏阴性细菌的广泛的消毒和杀生物作用,并且可以保持持久的杀生物活性。

    • A barbell comprises a bar 1 and a weight 2 mounted on the bar by the bar passing through a central hole in the weight. Hand-grip regions 3 of the bar are adapted to be gripped by the user during exercise, the hand-grip regions being positioned one on each side of the weight. The weight is elongate along the length of the bar and roughly square-shaped in cross-section, to allow the bar to pass close to the chest of the user during use. The center of gravity of the weight is displaced from the axis of the bar sufficiently for the weight to rotate relative to the bar during lifting by the user so as to avoid the twisting force of the weight due to its moment of inertia being transferred to the wrists of the user.
