    • PROBLEM TO BE SOLVED: To produce a biodegradable foam using an alginate and having uniform foam without using a peculiar chemical foaming agent.
      SOLUTION: The method for producing the foam whose foams are fixed comprises adding alginic acid, its salt or their derivatives to a foamable compound or a mixture containing the same as a main component and, if necessary, a coagulating component, foaming the mixture and then heating the foam at a temperature of a fixed temperature or higher. Since the obtained foam keeps foams in a constant size by the work of the foamable compound as a foam stabilizer or uses a thermally denatured protein to fix the foam, the foam having a constant foam diameter and a constant foam shape is obtained.

    • 要解决的问题:使用藻酸盐生产可生物降解的泡沫体,并且在不使用特殊的化学发泡剂的情况下具有均匀的泡沫。 解决方案:泡沫固定的泡沫体的制造方法包括将海藻酸,其盐或其衍生物加入到可发泡化合物或其主要成分的混合物中,如有必要,将凝固组分发泡 混合物,然后在固定温度或更高的温度下加热泡沫。 由于获得的泡沫体通过作为泡沫稳定剂的可发泡化合物的工作将泡沫保持在恒定的尺寸,或者使用热变性蛋白质来固定泡沫,获得具有恒定泡沫直径和恒定泡沫形状的泡沫。 版权所有(C)2006,JPO&NCIPI
