    • PROBLEM TO BE SOLVED: To provide chalk highly safe, not causing chalk mark even in touch with skin directly, capable of suppressing scattering of chalk powder, and inexpensively producible by utilizing an eggshell of wastes. SOLUTION: The chalk is produced by the steps of washing an eggshell E of a hen with water, drying the washed eggshell E in a hot-air dryer, charging the dried eggshell E in a stirring separator, stirring while jetting high pressure water to separate and remove an egg membrane inside the eggshell E, thereafter drying the eggshell E from which the egg membrane has been removed in the hot-air dryer and pulverizing it into powder form with a crusher, classifying the crushed eggshell E with a mesh screen to obtain an eggshell powder with about 20 μm particle diameter or smaller, mixing 90 wt.% of the eggshell powder P with 3 wt.% total of bentonite and kaolinite, and 7 wt.% of carboxymethyl cellulose (CMC) as an adhesive, kneading the mixture and extruding into a rod shape by an extruder, cutting the rod by a prescribed length, and drying to be solidified.

    • 要解决的问题:为了提供粉笔的高度安全性,即使直接与皮肤接触也不会产生粉笔痕迹,能够抑制白垩粉末的散射,并且通过利用废物的蛋壳廉价地生产。 解决方案:白垩是通过以下步骤制造的:用水洗涤母鸡的蛋壳E,在热空气干燥器中干燥洗涤的蛋壳E,将搅拌的隔离蛋壳E装入搅拌器中,同时喷射高压 水分离并除去蛋壳E内的蛋膜,然后干燥在热空气干燥器中从其中除去蛋膜的蛋壳E,并用粉碎机将其粉碎成粉末形式,用筛网对破碎的蛋壳E进行分级 筛分以获得约20μm粒径或更小的蛋壳粉末,将90重量%的蛋壳粉末P与3重量%的膨润土和高岭石总量和7重量%的作为粘合剂的羧甲基纤维素(CMC)混合 ,通过挤出机将混合物捏合成棒状,将棒切割规定长度,并干燥固化。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide humidity-conditioning wallpaper that is produced by using an egg shell that is conventionally discarded, has a humidity conditioning function of adjusting indoor humidity to an adequate degree, has adequate strength, is inexpensive and has superior installability.SOLUTION: The humidity-conditioning wallpaper is formed by fixing particles of the egg shell on a paper substrate having air permeability. The wallpaper obtains superior performance for conditioning indoor humidity from a hygroscopic function of the egg shell, in addition to air permeability that the paper substrate originally has, is lightweight and is easily installed. The wallpaper also obtains a superior odor eliminating effect because the egg shell is a porous material, has high adsorptive capacity and thereby allows the whole wall to which the wallpaper is attached to accelerate deodorizing.
    • 要解决的问题:为了提供通过使用常规丢弃的蛋壳产生的调湿壁纸,具有适当的调节室内湿度的调湿功能,具有足够的强度,便宜并且具有优越性 可安装性。

      解决方案:通过将蛋壳的颗粒固定在具有透气性的纸基材上来形成调湿壁纸。 除了纸基材原有的透气性之外,壁纸还具有从蛋壳的吸湿功能调节室内湿度的优异性能,重量轻且易于安装。 由于蛋壳是多孔材料,所以壁纸也具有优异的除臭效果,具有高的吸附能力,从而允许附着有壁纸的整个壁加速除臭。 版权所有(C)2013,JPO&INPIT
